The research results were published in the international academic journal “Science Advances” on June 11. The discovery is the result of a six-year experiment. In the experiment, the scientists stored freeze-dried mouse sperm on the International Space Station (ISS) and exposed them to radiation.

Healthy offspring from freeze-dried mouse sperm stored on the International Space Station

Researchers once thought that radiation in space would damage the DNA in cells, and may inherit mutations in future generations, making reproduction impossible. Cancer caused by radiation is another worrying issue.

Sayaka Wakayama, a member of the research team and a scholar at Yamanashi University in Japan, said that the lack of freezers on the International Space Station hindered long-term research on living cells. Moreover, even the current NASA space radiation cancer risk model is based on data from Hiroshima and Nagasaki atomic bomb survivors, “not from real space experiments.”

To overcome these limitations, the researchers freeze-dried sperm samples from 12 mice, sealed them in small capsules, and transported them to the International Space Station by rocket without the need for a freezer.

“Unlike the Earth’s surface, there are many different types of radiation in space. For example, heavy ions, protons, and electromagnetic waves from solar flares,” Wakayama explained. “It is very difficult to irradiate and replicate all these types of radiation on the ground at the same time. , So I think DNA damage in biological samples can only be measured in space.”

Scientists regularly test a small number of samples, send some of them back to Earth after 9 months, and leave the other two batches on the International Space Station for 2 years and 9 months and 5 years and 10 months respectively. After testing, the researchers found that freeze-dried sperm stored on the International Space Station for a long time did not cause DNA damage.

Studies have pointed out that when rehydrated sperm cells are injected into fresh ovarian cells and transferred to female mice, “healthy space pups” will be born.

The researchers said that although X-rays and space radiation damage DNA differently, it is roughly predicted that freeze-dried sperm “can be stored on the International Space Station for more than 200 years without causing damage to DNA.”

A total of 168 pups were born from sperm stored in space for 6 years. Compared with control mice born from sperm preserved on Earth, these “space pups” have normal appearance and genetic activity. mode.

Scientists believe that more studies from similar airborne experiments can reveal the effects of radiation and the tolerance of life forms that stay in space for a long time.

The Mars rover is roaming on Mars

These discoveries are crucial for mankind to enter the space age. At present, Mars probes from the United States and China are roaming on Mars, trying to find signs of life. In the future, there are plans for manned missions to Mars.

Illustration. For ants and small animals, the resistance of the air helps them a lot and makes their falling velocity very slow, sometimes their acceleration is negative (due to the wind blowing up). Thus, ants are almost unharmed when falling from the roofs of high-rise buildings. All objects falling through the air have terminal velocities that depend on their size, shape, and mass. The terminal velocity of an ant (6.4 km/h, according to the physics department of the University of Illinois) would be vastly different from the terminal velocity of a human (about 200 km/h). “For rats and any small animal, there’s really no danger. You can drop a rat into a minehole nearly 1,000 meters deep and when it hits the bottom, it’ll be slightly stunned and run away. , provided that the ground is fairly soft.The air resistance acting on a moving object is proportional to its surface.If the length, width and height of an animal are divided by 10, respectively, the mass is its mass is reduced by 1000 times while the surface area is reduced by only 100. Therefore, the air resistance for small animals is usually 10 times higher than the driving force. Force isn’t usually a problem for an insect, it can be free-falling without danger, with the ability to grip.” Michael Kaspari is an ecologist at the University of Oklahoma (USA) who has studied the aerial activities of wingless ants. Research shows that when ants are facing a predator, they will jump right into the air from tall tree branches and use their legs to control the direction of flight to reach the tree trunk. The longer hind legs will help the ants glide through the air, helping them avoid falling into places they consider dangerous. With this ability, it is possible that the ant has found a way to cling somewhere before it falls to the ground, but whether or not the ant does, the ant will not die if it hits the ground. The most ancient creature that still exists to this day It is said that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to the biological kingdom, it is estimated that ants account for 15-20% of the total number of animals living on land. Ants are animals belonging to the order of membranes, the class of insects. Scientist Corrie Moreau and French colleagues published a study showing that ants appeared between 140 and 170 million years ago. That means they are the most ancient creatures that still exist to this day, despite the violent fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survivability is endowed by nature, for they show no sign of changing accordingly. Which means it’s very likely that an ant 170 million years ago and an ant today would be no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are present everywhere on earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the color is usually just red or black. Especially, there are new species mixed with white color. Ants are gregarious species, with a rather distinct social organization. Each ant nest has an average of about 100,000 children in a colony with a single mother (Christian ants can live up to 30 years). Here, there is something like the organization of a swarm life of bees. The vast majority of ants in the colony are worker ants (who only live for 1-2 years) – likened to the hardest workers on earth. The job of worker ants is to take care of the queen, incubate eggs, transfer eggs, raise baby ants, build burrows, find food, guard … Not many people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become a god, but are forever just “cool” feet from birth. until death. Ants are considered to be the strongest species because they can carry food 10 times heavier than themselves. But to transport that heavy amount of food, they must use collective strength in coordination. Together they carry the food they earn very easily, when thousands of them work together. Ants are everywhere, everyone can see them or be bitten by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as a tool to heal wounds. When a member of the tribe is injured, they will catch a few large ants in the swarm of “army ants” so that they bite on both sides of the wound, then remove the ant body, leaving only the ant head on the wound. Since then the wound does not bleed and heals quickly. And interesting things about ants Ants are animals with a fairly hygienic life. Specifically, the handling of dead animals. When one ant dies, the other ants in the colony will together carry the dead ant out of the nest, with the sole purpose of keeping it clean and avoiding infection or disease spread. The workers will take care of the carrying, under the command of an ant that is supposed to be in charge of the burial of the colony. It is also surprising to learn that ants are insects with very advanced organizational systems. Along with the Lord ant, worker ant, and burial commander ant, there are also ‘teacher ants’ Born, in order to have the necessary skills, they undergo a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In case the “student” learns slowly and “fails” in the test, they will be transferred to another job that requires less skill. Not only know how to find termites, but ants also know how to “livestock” to create food reserves. They feed on insects such as aphids and caterpillars to obtain the sweet substance secreted by these insects. When it’s time to harvest the sweetener from the insect swarm, the ants “milk” using their antennae. It is very interesting to know that ants bring with them the insects they nourished when they move to a new area. It’s no different than people taking livestock with them to more verdant places. People have talked about the extraordinary in the world of ants. They have no ears but perceive sound from ground vibrations, through sensitive sensors on the pins. They have the ability to exist to the point of fantasy despite the harshness of weather and climate. Therefore, ants are also one of the first creatures on earth to be sent into space by humans in an experiment to conquer the sky. Ants have poor eyesight, but they often use the earth’s magnetic field to navigate. They are considered the most intelligent insects when in the small head of ants there are more than 250,000 brain cells. As industrious animals, ants are also said to be “excellent athletes”. If an ant were about the same size as a human, they could run at an average speed of 55 km/h without ever getting tired. They are also able to lift an object 50 times its own weight with extraordinary strength.

When the Earth’s temperature rose and the amount of oxygen in the oceans decreased about 252 million years ago, most life on our planet suffered the same tragic fate. It is estimated that this extinction event, also known as the “Great Dying”, killed 70% of species on land and about 96% of species in the oceans. Illustration: Getty However, there are no sharks among them. “They’re the last surviving species,” said Elizabeth Sibert, a paleontologist and identifier of fossils and an oceanographer at Yale University. The next extinction event at the end of the Triassic period or even the meteorite event that wiped out the dinosaurs 66 million years ago could not have caused the shark to become extinct. The shark’s survival or longevity is extraordinary, but the animal was also close to the brink of extinction, a study in the journal Science revealed June 3. The study, led by scientist Sibert, shows that a previously unknown extinction event pushed sharks to the brink of extinction 19 million years ago, leaving just one in ten of the sharks. Sharks in the oceans survive. “Something happened and wiped out 90% of the shark population overnight,” said scientist Sibert. The so-called something is still uncertain but it has caused immense destruction. The meteorite that wiped out the dinosaurs on Earth only caused 30-35% of the shark species to be wiped out while the above event was 2-3 times worse. To find this discovery, oceanographer Sibert and his collaborator Leah Rubin went through a remarkable process. Discover the mystery When a marine species dies, its body will fall to the bottom of the sea and decompose into discrete parts. Small parts, such as their teeth, will gradually accumulate in the sediments under the sea. “The seabed is essentially a grave for all aquatic species,” Sibert said. The sediment samples used in this study were collected from two locations in the Pacific Ocean, one in the north and one in the south, covering a period of 40 million years. However, it was not easy to analyze the small teeth inside each of these specimens. These parts are so small, even smaller than the width of a human hair. Oceanographer Sibert filtered dried sediment samples under a microscope and isolated the tiny bits of shark teeth. After separating them, scientist Rubin will identify and describe the features, as well as classify them. These little bits of teeth can reveal a lot to us. There were about 1,300 small tooth pieces identified in the above study with 85 samples with different shapes. Most of them are from the period before 19 million years and only a few samples belong to the later period. So, the question arises, what happened to the sharks? The tip of the iceberg The small tooth fragments suggest a decline in shark numbers and diversity about 19 million years ago, but the cause behind this event is unknown. “This is really a mystery. Right now we don’t know what happened,” Ms. Sibert said. The key to solving this mystery is to learn about the time when the sharks almost disappeared. This period is called the “Miocene” and is described by the scientist Sibert as the “transition phase” of the Earth. 15 million years before the mysterious shark event occurred, the Earth gradually became an “ice house” as permafrost increased in Antarctica. The oceans at that time were no different from the oceans of today, although we cannot find such species as tuna, swordfish and seabirds. Dolphins and whales had not yet evolved. However, there is not much evidence to find out the cause of the shark eradication. Even the discovery, which took place during a rather unusual time in Earth’s history, is just the tip of the iceberg. “There are many questions that need to be answered,” said researcher Rubin. Did some change in the environment lead to the decline in shark populations? This is difficult to confirm because the oxygen and carbon levels show no anomalies, but scientists can use more data around this time stamp. Did the event happen across the oceans and affect other marine species as well? Ms. Sibert said this is a global event but we still need more data. Also, what about other bodies of water? Can sedimentation in lakes and coastal areas occur other phenomena? How were terrestrial species affected during this time? Are there any chemicals that can tell us about the environment then? Ms. Sibert even thought that an epidemic, such as a virus, could be responsible for the decline in shark populations. Still, for this oceanographer, the extinction event was a remarkable phenomenon. The fact that sharks have existed for more than 400 million years, surviving multiple extinction events leads her to believe that something truly intense happened and that the sharks may be the gateway to understanding major changes. collided with Earth during the early Miocene. “There is a lot of data waiting to be discovered,” said researcher Rubin. The discovery not only shows the unpredictable change of the marine environment, but also shows how difficult it is for species to recover when they are pushed to the brink of extinction. “Biology is trying to tell us something and I think we need to listen,” Sibert said.

To ensure the good completion of this mission and the security of the atomic bomb, the 12 pilots were prepared to sacrifice themselves, once their bomber was shot down, they would end up with pistols or cyanide. before falling into enemy hands. To ensure that even if the mission failed, the secrets of the bomber’s bomb bay would not leak out of his mouth. Six bombers have a clear assignment. Two of them are used to detect the enemy’s situation, the other three need to observe weather conditions. The ultimate bombing target was the 82nd bomber. At 2:40 a.m., they began to slow down the runway and take off. The technical expert began to prepare to throw, open the safety device, install the fuse. At 7 a.m., the meteorological observatory sent back a report that the weather in Hiroshima was very good and the most suitable place to throw. Half an hour later, the 82nd bomber began to make the final preparations. Five minutes later, two enemy bomber scouts left early for safety. At 7:50, the bomber officially entered Japanese airspace. At 8:13, the bomber officially flew into Hiroshima, from the bomber, you can even see the buildings in downtown Hiroshima, as well as many small “ants” walking around. Those are the people who get up early and go out to work. At this point, the people of Hiroshima must have seen these bombers, but according to regular bombing drills conducted by the US military in the past, the people were already familiar with it, not not running away, but looking up. At 8:13, Major Ferrabi was also the bombardier on the mission, he found the Aioi Bridge target within range of the bombing, located in downtown Hiroshima. At 8:15 a.m. 17 seconds, the major opened the door of the bomb compartment, and the “little boy” fell from a height of 10,000m, rushing towards Hiroshima with the sound of demons howling. At the same time, the atomic bomber made a huge turn and flew wildly into a place nearly 90 degrees above the ground. Since it had less than 50 seconds left for it to escape, if it failed to enter the safe zone, Enola Gay would be blown to powder in this huge shock wave. At 8:16 a.m., the detonator detonated, two pieces of uranium 235 immediately merged into one, causing a chain reaction, within 43 seconds, “Death” lowered an altitude of 550 m above Hiroshima. At this time, the people of Hiroshima at the center of the explosion saw a large fireball suddenly rise above the city center, burned to ash by the temperature of more than 6,000 degrees, even to the point of time. Crying and crying can’t help. The bright light blinded thousands of people instantly, and the shockwave following the explosion directly destroyed the entire city. In just a few short seconds, the lives of 70,000 people were taken away by the “god of death”, within a kilometer of the center of the explosion, there was no sign of life, even the buildings were vaporized, dead silence. The fire spread throughout the city, the cries for help echoed throughout the streets, big and small. According to the memories of the survivors of each year, everyone’s facial skin was burned black, hair was no longer there, some people were completely unrecognizable, couldn’t even distinguish which one was the face, which was the head, whose skin was not stripped, hung there, as if cooked. There are also corpses burned to black coals that can be seen everywhere, living people step over corpses, people can’t be people, and demons can’t come out. It is estimated that more than 88,000 Japanese people were killed on the day of the atomic bomb in Hiroshima, the number of Japanese who died from nuclear radiation after the explosion could be even higher. On August 9, just three days after bombing Hiroshima, the Americans repeated the old trick and dropped another atomic bomb on Nagasaki, killing 86,000 people on the spot. After suffering the effects of two atomic bombs, Japan finally submitted a letter of surrender. In this regard, then-US President Truman said: “Only the sound of nuclear explosions can make the Japanese truly listen to submission.”

Sharks – “killers of the sea” – have caused many terrible attacks on people. An Irish man was recently nearly eaten by a shark while kayaking – but luckily the victim survived after being pulled out of the sea. 462 stitches after encountering a shark One survivor of one of the world’s deadliest shark attacks was Rodney Fox, then 23 years old. The tragedy occurred while Fox was participating in the 1963 South Australian Fishing Championships at Aldinga Beach. Fox was attacked by a great white shark. His entire abdomen was completely ripped and torn, all left ribs broken. Rodney Fox’s victim’s stitches are all over his body Rodney’s spleen and lungs were also damaged due to being ripped off by a shark. Rodney almost died from excessive blood loss. However, he survived after requiring 462 stitches. To this day, a shark tooth is still embedded in Fox’s wrist. Notably, Rodney – now 80 years old – has finally become a great white shark expert. He even designed and built the first underwater observation cage to dive with sharks. The woman was attacked by a shark right in front of her husband and children Portrait of victim Shirley Ann Durdin Among the deadliest shark attacks in history, Shirley Ann Durdin must be mentioned. Mother-of-four Shirley, 33, and her family vacationed in Australia’s Peake Bay in 1985 and were attacked by a great white while swimming in shallow water. The great white shark, believed to be up to 6m long, bit Shirley in half right in front of the victim’s husband and children. 4 people killed by sharks in 12 days The great white shark attacked the victims and was then caught by the fishermen. Between July 1 and July 12, 1916, four people were killed and one injured in a shark attack along the coast of New Jersey in the United States. The first attack occurred when 25-year-old tourist Charles Epting Vansant was taking a dip on the bottom of the Atlantic Ocean. The victim’s left thigh was eaten away by the shark and eventually Vansant died from excessive blood loss at the hotel. Other victims were 27-year-old hotel worker Charles Bruder, an 11-year-old local boy named Lester Stillwell, and businessman Stanley Fisher, 24, who died trying to save Lester. Only Joseph Dunn, 14, survived the horrific attack. It is believed that the great white shark in the photo below was later caught by the fisherman who caused the deaths of 4 ill-fated victims. Human bones were found in its intestines. The tragic death of the “child” surfing champion Victim Elio Canestri Elio Canestri – a 13-year-old “child” surfing champion had a tragic accident in 2015. The boy was attacked by a bull shark about 2.4m long while surfing with seven other people off the island of Réunion near Madagascar. The bull shark bit Elio in the stomach and threw him into the water. The area around Réunion Island is one of the most shark-infested in the world, with a total of 27 fatal attacks and 56 shark encounters since 1913. Groom killed by shark on honeymoon Redmond and Gemma Houghton couple In August 2011, newlyweds Ian Redmond and Gemma Houghton went to Seychelles for their honeymoon and decided to snorkel. They were reassured that there were no sharks in the area, but as Ian was swimming in the shallows off Anse Lazio beach, he was attacked by a shark. He was quickly brought to shore, but eventually died from excessive blood loss. Previously, a 36-year-old French tourist was also killed by a shark just two weeks before the tragedy. Hundreds of people were eaten by sharks Battleship USS Indianapolis In July 1945, more than 1,000 American service members fell into the Pacific Ocean when the battleship USS Indianapolis was torpedoed by a Japanese. In just four days, 579 service members lost their lives to sharks before a fighter jet found and rescued survivors from a terrifying shark attack. period.

Van Xuong fish. You probably never thought that an animal could live without a head, heart and bones. In fact, this species existed 500 million years ago and exists until today, in addition, they are also considered “cousins” of the ancestors of many vertebrates today. The family of vertebrates is extremely prosperous today, with more than 60,000 members, all of whom have different looks, habits and temperaments, but this “cousin” only has one child left. the only living species, they are named Amphioxus – Van Xuong fish, this species is also considered a living fossil. Although Van Xuong fish is called a fish and at first glance, it is very similar to a fish, but it is not actually a fish. On our planet today, most of the animals that exist are vertebrates, such as horses, cattle, sheep, chickens, ducks, dogs, cats, tigers, turtles.. Of course, there are us humans as well. What makes this particular “fish” so strange and unlike any other is that they are cephalopods, without a backbone, but still grouped with vertebrates, Chordates live and form the phylum Chordate. Biologists think that Van Xuong fish are animals in the transitional evolutionary stage from invertebrates to vertebrates, today they are considered to be ancestors of fish, but they are completely different. not fish. The skin of Van Xuong fish consists of two main layers: the epidermis (epidermis) on the outside and the dermis (dermis) on the inside. Unlike most vertebrates, their epidermis has only one layer of cells, while the dermis is underdeveloped, mainly composed of glue or elastic connective tissue. There are more than 66,000 animals in the order Phylum Chordata. The most special thing is that vertebrates account for the largest proportion, with more than 66,000 species, the main subphylum is the sea squid, and there are currently about 3,000 known species; and cephalopods, there are only two families of Van Xuong and Asymmetron fish – there are 30 species. In fact, the skeleton of this fish is the rope that runs along the body and back from the tail to the head. In the gill slit region, the skeleton is a network of many horizontal and vertical connecting rods. The fins and tentacles are also supported by the connecting rod. Their central nervous system is a neural tube running along the body, located above the spinal cord but not reaching the end of the spinal cord, wrapped in a protective glue membrane. Although Van Xuong fish looks like a fish, the biggest difference between it and vertebrates is that it does not have a real head, sense organs such as smell, sight and hearing, even a skull or a skull. teeth are also something too fictitious for them. This animal only has a tuft of elastic “legs” on the head that acts as support for the body. The most amazing thing is that it doesn’t even have a heart, instead it relies on the beating of a portion of blood vessels to transport blood. Their musculature is less differentiated and typically segmented. Therefore, the muscles can only guarantee simple bending movements, suitable for the lifestyle buried in the sand. The muscular system consists of many muscle segments (myomera), arranged from the anterior end to the posterior end of the body. The muscle segments are separated by septa of connective tissue (myosepta). The muscle segments on both sides of the body are arranged alternately with comb teeth. As a result, when swimming, the body bends in the horizontal plane. Amphioxus is widely distributed in the shallow waters of the ocean, Qingdao and Xiamen in China are their main habitats. In addition, there are the coasts of Southeast Asia and the coasts of California and Florida, Norway, the Mediterranean and Africa. Due to its rich nutrition and delicious taste, Van Xuong fish is considered a traditional delicacy in Southeast Asia. Van Xuong fish is 3 to 5cm long, very strange shape. The long, flattened body looks almost like a pole. The whole body is pinkish-pink, semi-transparent, the muscle fibers are clearly visible. They have no scales, no fins, no spine, their internal organs are just a rhythmically pulsating complex tube. There are no senses like eyes, nose, ears. There is no decomposition for the gastrointestinal tract. Apart from the mouth and pharynx, the only remaining part of the intestine is the intestine leading to the anus. Van Xuong fish often follow the tide to swim into the estuary where the seabed is shallow, almost defenseless but capable of penetrating the ground. Their lifespan is about 3-4 years, they often bury half of themselves in the sand, while the other half is exposed to receive plankton from the river. Their musculature is less differentiated, so they can only move in the water by simple bending movements. When not moving, they often bury themselves in the sand. The respiration of Van Xuong fish is also similar to other fishes. They vibrate the cilia (the tentacles in the mouth) to bring water from them to the gill slit. The wall of the gill slit has many blood vessels, where gas exchange occurs.

USS San Francisco was one of the first Los Angeles-class nuclear attack submarines of the United States, built in 1972 and commissioned on April 24, 1981. It is also the quietest submarine in the US Navy. The bow part of the ship was crushed after hitting a mountain. Photo: National Interest USS San Francisco has a displacement of 6,900 tons when submerged, 110 meters long and 10 meters wide. The train is equipped with a General Electric PWR S6G nuclear reactor with a capacity of 35,000 horsepower, helping it to move at a maximum speed of 61km / h. According to the National Interest, the accident occurred with the Los Angeles-class submarine USS San Francisco (SSN-711), on January 8, 2005. At the time of the collision, the ship was near Guam conducting training and preparing to sail to Australia. At that time, the ship was diving at a depth of 160m and moving at a great speed, more than 48km / h. The impact was very strong. The sailors present in the dining room were thrown into the air. In a 60-minute interview, Brian Barnes, a submariner, recalled: “I just saw people lying everywhere. Glass was broken, dishes were splattered, sailors groaned from their injuries, screamed.” The bow of the USS San Francisco was severely damaged, 30m of the front hull was flattened and exposed to the sea. Water flooded the submarine. The urgent task at that time was to urgently pump compressed air into the ballast tanks of the submarine to help the ship float to the surface. The USS San Francisco has a total of 127 crew members. The collision left 98 people injured and many of them were unable to continue operating the ship. Sailor Joseph Allen Ashley was wounded in the head and later died. Another sailor broke both arms but still managed to open the submarine’s air valve to fill the ballast tanks. Danny Hager, who monitors the submarine’s depth gauge, had a terrifying experience after the valves were opened. “I told everyone that the ship was at a depth of 160m. And I kept waiting, 5 seconds, 10 seconds passed and so on I don’t know how much longer, the ship was still at a depth of 160m. The atmosphere is very calm because everyone is waiting for me to announce that we are preparing to come up.” The problem was that the ballast tanks at the front were broken in the collision. The air escapes to the outside. 60 seconds passed and the ship remained unchanged in depth. Fortunately, the aft part of the submarine began to point upwards as the ballast tanks at the aft were filled with compressed air. Danny Hager now feels less worried: “It feels really relieved when I announce the ship has risen to a depth of more than 152m”. Finally, the USS San Francisco also surfaced, but the journey home is still quite far. Fortunately, the nuclear reactor was not damaged in the impact. The crew steered the ship back at a speed of 16km/h and so to return to Guam, it took the ship 52 hours. Unexpected causes Despite its immense firepower and nuclear propulsion, the USS San Francisco, like all submarines, relies on charts providing data on the topography of the seabed. After the investigation, the US Navy found that the submarine used old charts that did not mention the submarine mountain range in the area of ​​​​the ship’s operation. Meanwhile, other maps warn about this mountain range. The charts used by the crew of San Francisco were provided by the Defense Mapping Agency in 1989. By 2008, a study by the University of Massachusetts showed that images obtained from the Landsat satellite showed An underground mountain range more than 30m above the seabed in the area. However, the US Navy did not update this information to the chart. During the repair, the bow of the USS San Francisco was removed and replaced with the bow of the submarine USS Honolulu, which was about to be decommissioned. USS San Francisco rejoined the fleet in 2009 and served for another seven years. It was later converted into a training submarine. Ship commander Kevin Mooney was reprimanded for this unfortunate accident. Several sailors received medals for their brave actions when the ship was in distress. Only the sailor who died Ashley is inscribed at the Navy Memorial in Washington DC So how could the ship survive the high-speed crash into the underground mountains? In 1963, after the sinking of the submarine USS Thresher, the US Navy established the SUBSAFE program. The goal of this program is to ensure that the hull will remain pressurized in the event of an accident and that it can float. This program makes keeping nuclear reactors safe and making them recover from accidents a top priority. If the ship can surface and the nuclear reactor continues to operate, the crew will have a good chance of survival. USS San Francisco has ensured those conditions. Thus, the fact that the USS San Francisco can “survive the accident” is the result of the dedication and relentless research efforts of the US submarine force.

The apocalypse has arrived! That’s what happened in the movie Love and Monsters . An asteroid about to hit the Earth, humans launched rockets to destroy it, and succeeded. But as if fate had decided, the end of the world did not come one way, it had to come another way. “Love and Monsters” is set in a post-apocalyptic world. The chemicals used to build rockets exploded onto the ground like rain and changed the cold-blooded animals. They suddenly become giant and eat humans easily. In the past to kill a cockroach, one only needed a shoe, but now a whole tank might be needed and it might still not work. “Don’t be in peace, even in the end of the world!” Amidst the post-apocalyptic setting, the protagonist Joel Dawson is certainly not the typical hero model. Lovely but inexperienced, he has absolutely no survival skills. The crossbow shooting technique was almost hopeless, the direction was poor, and if there was a serious problem, he froze both his mind and his limbs. This is a … crab! Cold-blooded creatures mutated abruptly on the ground, so for safety Joel lived in a cellar with a few other survivors, for seven years. But one Joel-out-is-dead-probably decided to leave that safe place to go find his girlfriend in high school. That hurricane trip forged Joel. Truly things that don’t kill you will make you stronger. In the end, he was a braver, wiser, more capable person who knew when to run away and when to fight. Things that don’t kill Joel will make Joel stronger. Man is not born to be lonely Love and Monsters paints a post-apocalyptic world, but it is just too cute. The film has overcome the typical gloom of films in the same setting. Joel brings humor, joy but at the same time brings pain of loss, loneliness in the now lonely world. The disaster caused Joel, like many others, to lose loved ones and friends, to live in underground bunkers for many years. Even a robot can make the world less lonely. The old world was gone, part of Joel’s life was gone. Joel now has to live in the cellar, when it is time to go outside, only to stumble, fall again, fall forever. 7 days wandering on the ground dozens of times almost lost their lives. But a fool has the merit of being a fool, Joel receives unexpected help when he needs it most. It was a dog that kept the former owner’s dress. A robot with artificial intelligence. “Survivor” Clyde is brave, seasoned and sharp, 8-year-old Minnow. All of them taught Joel the knowledge of the new world, trained him in his skills, talked to ease his loneliness, and most usefully – gifted a grenade to the toughest beast at a time of danger. . Joel was a companion dog. And learned in theory and practice by an old person, a child who is a “survival expert”. Love and Monsters stresses the human need to connect, questioning how far one will go to find it, despite the dangers that may exist on the journey. Because we’re not made to be lonely. You always have a talent to surprise the world Joel is always left behind by the siblings living with him when he goes out in search of food, because Joel can not only endanger himself but also his teammates with negative survival skills. Joel’s talent is to draw, he has been drawing for the past seven years. But what effect does drawing have in the post-apocalyptic world? But there is! Joel shot the crossbow so badly that the “teacher” almost gave up. Joel painted the monsters he met, the strange plants, added captions such as features, features … In the end, that book became a useful survival guide for everyone. They could know which beasts were dangerous, which monsters could be friends, what edible plants, which poisonous fruits … Maybe Joel didn’t become the usual “hero”, but he became a who inspired everyone to live happier in the midst of the apocalypse. But she is the best-seller of the book of apocalyptic survival handbook. Love can change, but it can also return Seven years have passed since the disaster, Joel is 24 years old this year, but he still misses his girlfriend Aimee – who is in another bunker. Joel maintained contact with Aimee over the radio, and then one day decided to go see Aimee even though it was unsafe. If the world is already the end of the world, why should we still live without love? Joel fell in love with an Aimee seven years ago. Before starting the trip, Joel should have asked Aimee, “I’m coming to see you, are you as excited as I am?” Because seven years have passed, everyone is different, including Aimee. But it is hard to blame Joel when he is too naive and romantic. When tragedy strikes, Joel is just a teenager and Aimee is Joel’s sweet (and only) first love. Joel’s apocalyptic social relationship was so poor, there was only one cow and one robot that was no longer active, and everyone else had a couple. Seven years has forged a very different Aimee, Joel must also grow up. Time was different, the world was different, of course Aimee and her love were also different. After overcoming his initial feeling of disappointment, Joel understood that that was what had to happen, and this desperate journey was still worth it in the end. And when Joel matured, that was the time when love returned.

Shark – “killer of the sea” – has caused many terrifying attacks on people. An Irish man was recently almost eaten by a shark while kayaking – but luckily he survived after being dragged out of the sea. 462 stitches after a shark encounter One survivor of one of the world’s most horrifying shark attacks was Rodney Fox, then 23 years old. The tragedy occurred while Fox was participating in the 1963 South Australian Fishing Championship at Aldinga Beach. Fox was attacked by a great white shark. His entire abdomen was ripped open and completely torn, all of his left ribs were broken. Sewage stitches were all over the victim of Rodney Fox Rodney’s spleen and lungs are also not intact due to the sharks ripping off. Rodney almost died from losing too much blood. However, he survived after having to get 462 stitches. To this day, there is still a shark tooth still on Fox’s wrist. Notably, Rodney – now 80 years old – finally became an expert in white shark. He even designed and built the first underwater observation cage to snorkel with sharks. The woman was attacked by a shark in front of her husband and children Portrait of victim Shirley Ann Durdin Among the most terrifying shark attacks in history, Shirley Ann Durdin is the case. Mum of four, Shirley, 33, and her family arrived in Australia’s Peake Bay for a vacation in 1985 and were attacked by a white shark while swimming in shallow water. A giant white shark that is thought to be up to 6m long has bit Shirley in half right in front of the victim’s husband and child. Four people were killed by sharks in 12 days The giant white shark that attacked the victims was then caught by fishermen. Between July 1 and July 12, 1916, four people were killed and one injured by a shark attack along the US coast of New Jersey. The first attack happened when tourist Charles Epting Vansant, 25, was soaking in the bottom of the Atlantic. The victim’s left thigh was eaten by a shark and eventually Vansant died of excessive blood loss at the hotel. The other victims were 27-year-old hotel worker Charles Bruder, an 11-year-old local boy named Lester Stillwell, 24-year-old businessman Stanley Fisher, who died trying to save Lester. Only Joseph Dunn, 14, survived the horrifying attack. It is thought that the giant white shark in the photo below was later captured by fishermen who caused the death of four unfortunate victims. Human bones were found in its intestines. The catastrophic death of surfing champion “kid” Victim Elio Canestri Elio Canestri – a 13-year-old “kid” surfing champion had a catastrophic accident in 2015. The boy was attacked by a shark about 2.4 meters long while surfing with seven other people off the coast of Réunion island near Madagascar. The bull shark bit Elio in the stomach and threw the boy into the water. The area around the island of Réunion is one of the sharks in the world, with a total of 27 fatal attacks and 56 shark encounters since 1913. The groom was killed by a shark during his honeymoon Redmond and Gemma Houghton In August 2011, newlyweds Ian Redmond and Gemma Houghton went to Seychelles for their honeymoon and decided to snorkel. They were reassured that there were no sharks in the area but while Ian was swimming in the shallow water off Anse Lazio beach, he was attacked by a shark. He was quickly brought ashore, but eventually died of excessive blood loss. Earlier, a 36-year-old French tourist was also killed by a shark two weeks before the tragedy struck. Hundreds of people were eaten by sharks Battleship USS Indianapolis In July 1945, more than 1,000 US servicemen fell into the Pacific Ocean when the USS Indianapolis was hit by a Japanese torpedo. In just four days, 579 soldiers lost their lives to being eaten by sharks before a friendly bomber found and spiritually rescued the survivors from the terrifying shark attack. period.

Bright Side brings together 10 rare creatures that are on the brink of extinction. Global mountain gorilla Currently the mountain gorilla has increased to about 1,063. They can only be found in protected forests. This is evidence that conservation efforts can bring a species back on the brink of extinction. However, illegal human hunting remains a major threat to the fauna of Bwindi-Sarambwe. Sao la The saola species was discovered in the Annamite forests of Vietnam. The main threat to saola is hunting activities and environmental climate impacts. That is why many conservation organizations have collaborated to create a safe environment for them in nature. Animal with dunnart bag This tiny creature can only be found on Australia’s Kangaroo Island, with an estimated population of less than 500. The widespread cleaning of the vegetation by humans has put the dunnart in a very dangerous situation. In addition, wildfires in Australia in 2019 and 2020 have burned 95% of the species. That is why a closed sanctuary was created to keep dunnart and other endangered species safe. Iberian lynx This rare species can only be found in the jungles of southwest Spain. From 1985 to 2001, their population decreased by 87%; So far, there are about 400 lynx in the wild. Their natural habitat continues to be destroyed by new highways and cut down trees. Black-footed ferret While people thought they were extinct, tiny creatures have proven to still exist. However, their population is rapidly declining due to disease and the loss of their natural habitat. Their total population is estimated at around 370 in the wild. Massive restoration efforts by many federal agencies and zoos have provided space for the weasels to survive. Gharial crocodile In 2010, only 15 crocodiles were found in the Gandak River in Bihar. That’s why in 2014, a conservation initiative freed 30 crocodiles from captivity and returned them to the river, and their population began to increase. Kakapo For the first time in 70 years, the kakapo population is increasing with about 213 species of birds existing. Only during the 2018-2019 breeding season, 71 young survived, which is a record number for this species. The recovery team tries to make sure the birds stay healthy and protected from infection. Their next goal is to find a good habitat for the birds as disease is their main threat. Canadian harbor seals Found in Quebec, this is the only species of its kind that can only survive in fresh water thanks to fish. To date, only more than 100 live in the area. The cause can be attributed to human hunting. Also, in many cases, seals get trapped in their gears and cannot free themselves. Leopard Amur This leopard has found a way to survive in the jungle in the Russian Far East. They live up to 15 years in the wild and more than 20 years in captivity. They have an amazing ability to run very fast and jump high. However, the loss of habitat and human activity has reduced their number to about 84 individuals. Vaquita dolphin This very rare marine mammal was discovered only in 1958. However, in recent years, vaquitas dolphins have been victims of illegal fishing activities. They are often trapped in fishing nets. That is why their population is only about 10 in the Gulf of Mexico. They can be found in shallow water but will quickly swim away if a boat approaches them.

Priz AS-28 was successfully rescued New chapter in rescue history In the military history of the United States, the rescue of the Sargo-class USS Squalus submarine of the US Navy has become a major event and also a lesson in operational deployment of submarines. The incident took place on the morning of May 23, 1939, the Sargo-class submarine USS Squalus with 59 crew members began their usual test dives off Portsmouth, New Hampshine, without knowing they were about to experience a disaster. USS Squalus was the new and best submarine of the US Navy at the time. The ship was launched in September 1937 and has undergone 18 successful trials. No one thought it would fail on the 19th test, because all the systems on board were still working fine. However, due to a technical error, the technician wrongly announced the coordinates of the submerged vessel up to 8km down. Squalus dives while the main air intake valve remains open, causing tons of seawater to enter the engine bay at the rear of the ship. The sailors on board were shocked to hear the news and rushed to find a way for the ship to float. They built flooded compartments and tried to close the air intake valves but failed, before putting compressed air into the ballast tanks to allow the ship to float. The Squalus is stable with the bow pointing upwards. However, when the sailor tried to prevent seawater from entering through the vent pipe, there was a tremendous increase in pressure. The sea water suddenly flooded the front compartments and the ship began to sink to the ocean floor due to the large amount of seawater. The incident caused 26 sailors at the back of the ship to be immediately killed by water, 33 men in front of the ship survived. The Squalus sank to the bottom with the bow pointing upward at an angle of about 11 degrees, lost power completely, was unable to communicate and was in waters with temperatures just above freezing. The Sculpin was then dispatched to the Squalus’ coordinates on the last contact, but did not detect any signs of disaster such as debris or oil spills. No one aboard the Sculpin knew that they were 8km away from where the submarine was sunk. Meanwhile, the surviving sailors aboard the Squalus try to send out a call for help. Captain Naquin quickly ordered the release of a floating buoy attached to the cable and left a phone inside with the words “submarine sinks here, there is a telephone inside”. The crew constantly fired smoke bullets out, as well as pumped oil through the toilet so that the rescue team could detect smoke and oil spills in the sea. A sailor aboard Sculpin detected a streak of smoke rising into the sky and reported to the captain. The Sclupine arrives, finds the beacon and cell phone and communicates with the Squalus ship. That night, the US Navy deployed several ships anchored around the search area and turned on the headlights on the sea surface, while the crew on the Sclupine submarine tried to get close to the Squalus. The Squalus submarine salvage was rejected because it was too dangerous and risky. The rescuers had only two options: to transfer diving equipment to sailors to float to the surface, or to use a rescue cocoon from above, but this equipment had not been verified. The first option was canceled because when the sailors exited the submarine, it was very susceptible to cold and high pressure under the sea. The next day, the divers used the rescue cocoon. They performed four rescues with the last man on the surface at midnight May 25. This rescue campaign opened up a new chapter in the history of underwater rescue. Difficult to save because of “invisibility” Military submarines are originally designed to travel undetected under the ocean. Except when there is a need to contact headquarters, the ship will not transmit any signal. Meanwhile, the submarine detector is only really effective when finding a ship that is “in the middle of the sea or floating on the surface”. In fact, the submarine’s submarine stealth is a double-edged sword. With each passing hour, the hopes of saving the ship became less and less. Sailors will have to reduce their activity and move to reduce their oxygen consumption while they wait to be rescued. Although they have been trained in emergency self-rescue, their chances of survival depend on the depth of the ship. On August 5, 2005, the Russian submarine Priz AS-28 and its crew of seven were trapped at a depth of 190 meters below sea level after the propeller was caught on an undersea cable. The sailors were trapped in darkness on the cold ship and the oxygen supply dropped. This accident has attracted much attention because it happened just five years after the sinking of the nuclear submarine Kursk (in 2000), killing all 118 sailors. The Russian government immediately requested US and UK assistance; at the same time to plan to rescue the ship. The first was the scheme to detonate the anchor system of the Russian surveillance antenna system installed under the sea (weighing 60 tons), but was rejected because it was not feasible. By the end of August 6, the command decided to hook the cable to the ship, tow the ship up close to the water surface so that the crew could rescue the sailors. But this plan also failed. On the night of August 6, the race against time reached its peak because the oxygen in the train was only able to endure until August 7. The British Super Scorpio 45 unmanned submersible has entered the game. According to commander Jonty Powis, an expert on British submarine rescue and rescue, the campaign went smoothly. The ship has successfully severed the cables that are clutching the Priz submarine. Commander Powis praised the Russian government’s openness to allow rescue parties to intervene in the area that was once one of the most secretive parts of the Soviet Union before. After just 3 days of being stranded under the sea, the ship finally emerged. All 7 crew members are healthy. Although suffering from the cold and the oxygen in the ship was gradually running out, when rescued, sailors were able to open the submarine’s cover and move to the lifeboat without assistance. According to the examination results at the hospital, the health of all 7 people was still normal and did not need any special treatment. This shows that the crew responded very professionally to the extremely strict situation in the ship stranded at a depth of 190 meters under the sea. They wore insulation to keep their bodies warm, maximized energy savings by only intermittent contact with the mainland and tried to stay calm so as not to lose the meager oxygen on board.

There are four reasons to consider whether to close your bedroom door at night. Increase your chances of surviving a fire If there is a fire while you are sleeping, closing the door will give you time to handle it and find a safer way out of the fire. Because if you open the bedroom door, toxic smoke and fire will quickly spread. Even if you are asleep, you may suffocate or pass out before you detect a fire. That’s why experts recommend closing your bedroom at night to increase your chances of surviving a fire. In addition, the door also helps to prevent toxic smoke and heat from outside flames to a certain extent. According to feng shui, the closed door will keep positive energy inside According to feng shui, closing the door will help retain positive energy. Therefore, one of the principles of feng shui is to avoid sleeping in an open room to limit negative energy from entering the room. In addition, closing the bedroom door will bring a sense of safety and peace. From there, the quality of sleep is higher and your health is ensured. In case of intrusion theft Bad guys are more cautious in case your house or bedroom is closed. Therefore, the bedroom door is closed to help you stay safer when an unforeseen situation occurs. You can even call for help or the police if you detect something unusual or strange noises in your home. Prevent noise for deeper sleep The bedroom door not only helps you have a private space, but also prevents noise from outside. If you live in a busy area or next to a highway, closing the door will help you sleep better and better. In particular, you will not suddenly wake up because of car sirens or noise from the rest of the house. Sponsorship news

In the dark, rescuers found a young Chinese man clinging to a wooden door, trembling but alive. It was Fang Lang, one of six Chinese who survived the tragedy and the rescue that later inspired a famous scene in the 1997 Hollywood blockbuster “Titanic”. Titanic was the largest ocean-going ship in the world in the 1910s. It was described as “invincible fish” before sinking in the Atlantic in 1912. Photo: Easyvoyage However, miraculous survival is not the end of their trials. Within 24 hours of arriving at the immigration screening station on Ellis Island, New York, they were deported from the United States for a controversial law banning mainlanders from immigrating in the country. According to the BBC, 6 men disappeared from history to the present day. A documentary film has just been released on the mainland titled “The Six” has clarified their identity and life, 109 years after their fateful trip. The film unfolds the story outside of the legendary Titanic, a story shaped by racism and anti-immigration policies that are gaining special attention following the recent wave of persecution of Asians in the United States. Who are the 6 Chinese survivors? The men were identified as Lee Bing, Fang Lang, Chang Chip, Ah Lam, Chung Foo and Ling Hee. They are believed to be sailors coming to the Caribbean to work. Arthur Jones, British filmmaker and director of The Six, told the BBC that they were known as a group, not as an individual. A ticket listing the names of eight Chinese guests aboard the Titanic. 6 of them survived the shipwreck tragedy. Photo: LP Films The names of the Chinese survivors were on the list of passengers on the Titanic. Articles covering the sinking of the Titanic also briefly mentioned them. However, according to historians and researchers, unlike other survivors who had been praised by the media, this group of Chinese people was vilified for their anti-Chinese views in the West in the early 20th century. For example, in a report published a few days after the sinking, The Brooklyn Daily Eagle called the Chinese survivors “creatures” that rushed into the lifeboats “at the first sign of danger. and hide under the seats. However, research by the documentary production team shows that this claim is false. They built a replica of the Titanic’s lifeboat and found that it was impossible for the Chinese men to hide underneath without being spotted. “I think, we see the same thing today. We are seeing immigrants turned into scapegoats,” commented director Jones. Lifeboat took survivors away from the sinking area of ​​the Titanic in April 2012. Photo: Easyvoyage Other media have even accused the Chinese of dressing up as women in order to be given priority on boarding the lifeboats. But Tim Maltin, the Titanic historian, says there is no evidence that the survivors of the Chinese had either stowed away or disguised themselves as women. Mr. Maltin believes, these are stories made up by the press and public opinion after the event. Rumors may stem from the stigma attached to many male survivors, as the vast majority of the general public believes that women and children should be given priority in the rescue. According to the historian Maltin, Chinese men tried to help other survivors. Fang Lang, who tied himself to a floating door in the sea, later steered the lifeboat that helped bring many people to safety. What happened to them after the crash? Rejected by the US, six Chinese men were sent to Cuba. They quickly made their way to England, where there was a shortage of sailors as many British sailors enlisted in World War I. (From left to right) Three of the Chinese guests who survived the tragedy with the Titanic were Ah Lam, Fang Lang and Ling Hee. Photo: LP Films Chang Chip became more and more ill after the fateful night and eventually died of pneumonia in 1914. He was buried in an unmarked grave in a London cemetery. The remainder worked together in Britain until 1920, when the country experienced a post-war recession and anti-immigrant sentiment surged. Some are married to British women and have children. However, anti-immigrant policies force them to leave the country without notice, leaving their relatives behind. “It’s not their fault. All these families have been divided because of politics, which they really don’t have any control over,” said director Jones. Lee Bing immigrated to Canada, while Fang Lang, after taking a train between Britain and Hong Kong for many years, became a citizen of the United States, the country that once rejected him. Similarity between history and today Tom Fong, son of Fang Lang was born in Milwaukee, Wisconsin, USA almost half a century after the sinking of the Titanic. His family surname has many different spellings in English. For decades, Fong was unaware of his father’s experiences aboard the legendary ship, dubbed “unsinkable”. “My father never mentioned it. At least not to me or my mother,” said Fong. Tom Fong was not told by his father – Fang Lang about what he experienced. Photo: LP Films Mr. Fang died in 1985, at the age of 90. Only 20 years later, his son was revealed by a family member that the father had survived the terrible shipwreck. Fong thinks his father may have kept it a secret because of his hurt and discrimination. “There was a lot of information saying that they were sneaking under the boat and disguised as women … stories like that were widely spread at that time,” Fong stressed. As The Six’s team traces the descendants of survivors, many of them still hesitate to share stories of stigma that family members experienced a century ago. Over the past 100 years, the hostility suffered by the six Chinese survivors has been eerily repeated in the midst of anti-Asian racism arose in today’s pandemic scene. In the US alone, there have been thousands of abuse cases reported in recent months, ranging from spit, verbal harassment to violent assault. Fong decided to share his family’s story in the hope that everyone will learn the truth about the Chinese survivors of the Titanic disaster and reflect on current events. “Because if you don’t know history, it will repeat itself,” he asserted.

Most wild deer have no contact with humans. However, when threatened and during heat season, wild deer will probably attack you. In this case, calm down and slowly step back. If it shows signs of rushing to attack you, put an obstacle between you and the deer and run away or climb the tree. In case you can’t run away or can’t climb the tree, raise your arms and spread your jacket open for a creepier look. When attacked by a deer, protect your head and neck by curling up like the pose shown in the photo above. 2. When meeting a bear The bear does not usually come near noisy areas, but in case you happen to encounter a bear in the forest, absolutely do not scream or run away or climb into a tree, as the bear runs very fast and can break the tree. Easily. Make yourself look bigger by reaching up high, holding your backpack or jacket over your head, and slowly backing away. Once you are out of sight of the bear, you can run away quickly to safety. 3. When meeting a lion Mountain lions often attack prey from behind so never turn your back on it or run away because you definitely cannot run faster. You need to be more fierce than it is. You stand up straight and look him in the eye, hold your coat up high to look more scary. If necessary, throw whatever you have at it. If a mountain lion attacks, do not stand still but fight back. Try to hit its eyes, nose, and mouth and it may leave you alone. 4. When meeting wolves Wolves often live and move in groups. If you see a wolf it means others are probably also around. So, if your wolf sees a fairly large distance from you, slowly walk away in silence until you reach safety. However, if the distance between you and the wolf is very close and it has noticed you, here’s what you should do: – Slowly step back and don’t look away. – If the wolf comes close, scream as loudly as possible at its face and throw whatever is on it at it. Pay attention to your footsteps, for if you stumble, the wolf will pounce on you immediately. – In that case, attack with the most forceful force on its eyes and nose. When it sees you as a dangerous subject, it leaves. 5. When meeting a bison Keep your distance from the bison, as the bison will only attack when someone approaches it. Don’t be fooled by their slow, gentle appearance, bison can run three times faster than a human and have very strong vigor. If you accidentally approach a bison and see signs of wanting to attack you, give up. Find shelter behind trees, rocks, or any other object large enough to hide or climb on trees. Once you see that the bison has moved away, you can now move to safety. 6. When you meet the newspaper Never go near a leopard, especially cheetahs. Cheetahs may not be intimidating, but their mother will attack anything that gets close to her to protect her. If you come across a cheetah, stand still and do not make eye contact. If the leopard is about to attack, shout, wave, clap, or do anything to make you look more dangerous. 7. When meeting the hyena Instinctively, hyenas will chase anyone who runs away. So when you encounter a hyena, calm down and talk to it. If you have food, throw it to the hyena. Hyenas are lazy animals and if there is something to eat, it will most likely leave you alone. If it approaches you, surprise them by taking a few steps toward it and making loud noises, waving, clapping, trying to look as scary as possible. The hyena will think you are about to attack and it will most likely run away. 8. When meeting a wild boar The wild boar is extremely ferocious. So if you spot a wild boar in the distance, don’t stop to take a photo but leave the area immediately. If you are too close to the boar, do not run away, but do the following: – Keep calm and step back slowly. – If it comes towards you, climb the tree. Boars cannot climb so after being bored they will leave. – If it goes crazy and decides to get along with you and you can’t find any place to hide, fight it. A fight with a boar usually lasts only about a minute, you should fight until it leaves. Dieu Linh (According to Bright Side)

All objects falling into the air have terminal velocities depending on their size, shape and mass. The terminal velocity of an ant (6.4 km / h, according to the physics department of the University of Illinois) will be much different from the human terminal velocity (about 200 km / h). “For rats and any small animal, there’s really nothing dangerous. You can drop a mouse into a mine nearly 1,000 meters deep and when it hits the bottom, it gets dizzy and runs away. , provided that the ground is quite soft The air resistance acting on the moving object is proportional to the surface of the object.If the length, width and height of an animal are divided by 10, then the mass. Its amount is reduced by 1000 times while the surface area is reduced by only 100 times, so the air resistance for small animals is usually 10 times higher than the actuation force. Force is usually not an issue for insects, it can fall freely without danger, with the ability to cling. ” Michael Kaspari is an ecologist at the University of Oklahoma (USA), who has studied the aerial activities of wingless ants. Research shows that when ants are confronted with a predator, they jump in the air from tall branches and use their legs to steer their flight to the tree. The longer hind legs will allow the ant to travel through the air, preventing it from falling into places they deem dangerous. With this ability, it is possible that the ant has managed to cling to something before it falls to the ground, and whether it can grip or not, the ant will not die if it lands. The most ancient creatures still exist today It is thought that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to biota, it is estimated that ants make up about 15-20% of the total number of terrestrial animals. Ants are animals belonging to the membrane wing, the layer of insects. Scientist Corrie Moreau and his French colleagues published a study that found ants appeared 140 to 170 million years ago. That means they are the most ancient creatures that still exist today, despite the intense fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survival is bestowed on nature, since they show no signs of consistent change. Which means it is very likely that an ant 170 million years ago and an ant now are no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are found all over the earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the colors are usually just red or black. Especially, there is a species with white color added. Ants live in herds, with a quite separate social organization. Each nest has an average of about 100,000 children in a herd with a single mother (God ants, can live up to 30 years). Here, there is something like the way bees organize the swarms of life. The great majority of baby ants in the herd are worker ants (who only live 1-2 years) – such as the hardest and most hardworking workers on earth. The job of worker ants is to take care of queens, incubate eggs, transfer eggs, raise young ants, build caves, forage, guard … Few people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become God prejudices, but are forever just “cu-li” legs from birth. to death. Ants are considered the most powerful because they can carry food 10 times heavier than them. But to transport that heavy food, they have to use collective strength in coordination. Together, they carry the food they can find easily, when thousands of them work together. Ants are everywhere, anyone can see them or be stung by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as tools for wound healing. When one of the tribe was injured, they would capture a few large ones from the “army ant” group so that they would bite on either side of the wound, then remove the body, leaving only the ants on the wound. From there, the wound did not bleed and healed quickly. And interesting things about ants Ants are animals with a fairly sanitary life. Specifically the handling of the dead. When one is dead, the other ants in the herd together carry the dead ants out of the nest, with the sole purpose of keeping clean, avoiding infection or disease spreading. Worker ants will take care of carrying under the command of an ant that is believed to be responsible for the funeral of the flock. It was also surprising that ants were insects with a very advanced organizational system. Along with God ants, worker ants, and the commanding ants of burial, there are also “teacher” ants. Born, to have the necessary skills, they go through a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In the event that “students” learn slowly and “fail” on a test, they will be transferred to another job that requires less skills. Not only know how to find termites, but also know “breeding” to create a food reserve. They know how to feed insects such as aphids and moths to get the sweetness they produce. When it is time to harvest the sweeteners from the insect swarm, the ants “milk” using their antennae. It is extremely interesting to know that ant colonies carry a swarm of insects that they cultivate when moving to a new area. It is no different than humans taking cattle along to places where the grass is lush. People have talked about extraordinary in the ant world. They do not have ears but senses sounds from ground vibrations through the sensitive sensors on their legs. They have the ability to survive miraculously despite the extreme weather and climate. That is why ants are also one of the first organisms on earth to be sent to space by humans in experiments to conquer the sky. Ants have poor eyesight, in return they often use the earth’s magnetic field to guide their way. They are considered the smartest insects when there are more than 250,000 brain cells in the small head of ants. As a hard-working animal, ants are also said to be “great athletes”. If an ant was about the size of a human, then it could run at an average running speed of 55 km / h without ever getting tired. They can once again lift an object 50 times its weight with incredible strength.

Put the shoes in the freezer Put your shoes in the freezer for 30 minutes. When the shoe is cold, you will find it a lot easier to walk. You could also try putting a water bag inside the shoes and putting them in the freezer. Frozen water will relax your shoes a little more, making you more comfortable. Use double-sided tape Tape the heel to the sole. This tip will keep your shoes fit at all times, but most importantly it will prevent blistering and soreness in your toes. Use high heels Specially designed for the sole, usually made of silicone or fabric, these socks will prevent your feet from slipping forward, reducing pain and blistering. Choose silicone if you’re wearing open-toed heels. The silicone pad is not visible under your feet but protects your feet very well. Moisturizer Apply a little moisturizer to your feet before you put on your heels to help keep your feet from rubbing, hurting, and blistering, especially if the shoes are new and tight. Baby powder If you have talcum powder at home, try sprinkling some on high heels. It will prevent sweat from slipping, reducing the risk of injury. Tape All you have to do is glue your third and fourth toes together with tape to reduce the pressure on the nerve between your toes, alleviating the pain. Don’t take off your heels Even if high heels are causing you extreme pain, taking them off is a bad idea. You should feel relief for a second, but the feet will most likely swell up immediately, bringing them back in even more painful. Wear high heels at home Put on high heels at home for at least a week before wearing them outside, especially if they are new and tight. This way, you will get used to your shoes and they can stretch to better fit your feet. Wax deodorant Before putting on your shoes, apply a little deodorant wax to areas that rub against the shoes such as heels, ankles or toes to avoid cracking or discomfort. Don’t stand still Even if you are in extreme pain, try to walk. Standing still on high heels will make you more painful. You can also sit down and rest for a while, but don’t take your shoes off. Proper foot care If your heels are cracked, your skin is hard and gritty, your high heels will only aggravate these problems and make you much more painful. So taking good care of your feet is a must. Choose the right shoes If you’ve never tried it before, don’t rush to buy heels that are pointed or too tall for you. They look more luxurious, but will make your legs hurt. Choose square heels and lower shoes. Bandage If you’re unsure of how comfortable your new heels are, just keep a few bandages and other blister treatment products in your wallet. They will save you if the shoes start to hurt you.

Is pledge a prelude to selling?

In the battle of Suning’s self-help, Suning Real Estate became the vanguard.

Suning Real Estate pledged its equity multiple times

According to industry and commerce information, on April 12, Suning Real Estate Group Co., Ltd. pledged all the shares of Chuzhou Suning Real Estate Co., Ltd., amounting to 10 million yuan, and the pledgee was Xinyu Hanyu Bijiang Asset Management Co., Ltd.

After the penetration of Yema Finance, it was discovered that Xinyu Hanyu Bijiang Asset Management Co., Ltd. and Country Garden Group have an associated relationship , The former legal representative Zhou Jinxin also serves as the legal representative of Foshan Nanhai Bijia Culture Communication Co., Ltd., which is controlled by the Guoqiang Charity Foundation under Country Garden.

This is not the first time Suning Real Estate has asked Country Garden for help.

On March 23 this year, Suning Real Estate pledged shares of its subsidiary Jiangsu Yinhe Property Management Co., Ltd. (hereinafter referred to as Yinhe Property) to Country Garden Life Service Group Co., Ltd. (hereinafter referred to as Country Garden Service). The pledged equity amount was RMB 30.01 million. Equivalent in capital.

According to market news recently, Country Garden will acquire Yinhe Property at a transaction price of 3 billion yuan, and the pledge of equity is actually a guarantee for the transaction. As of press time, Suning and Country Garden have not commented.

In addition to Country Garden, Industrial Bank, Evergrande and Ali are also pledgers of Suning Real Estate.

In January this year, Suning Real Estate’s shareholder Suning Appliance pledged part of its equity to the Nanjing Branch of Industrial Bank; in January-March, Suning Real Estate also pledged equity to Evergrande Life Insurance several times.

In December last year, the entire equity of Suning Holding Group was pledged to Taobao. At the same time, Zhang Jindong pledged 65,000 shares of Suning Real Estate to Taobao.

Regarding this equity pledge, Suning Tesco told Yema Finance at that time: “ Equity pledge is a normal commercial cooperation and has no material impact on Suning.com’s strategic development and normal operations . In the past 30 years, Suning’s innovation and development cannot be separated from the long-term strong support of strategic partners and relevant departments. Since the beginning of this year, in the face of the epidemic challenge, Suning has fully mobilized the advantages of the forward-looking layout of smart retail and realized the steady development of the enterprise. Suning and Ali have maintained good cooperation for a long time, and the two parties will further deepen cooperation and expand offline business scenarios. ”

Senior industry professionals said to Yema Finance that equity pledge financing generally requires a 50% discount. Equity pledge financing has low loan cost and fast time for enterprises, and has relatively little impact on the stock price of listed companies.

Focusing on the main business, where does Suning Real Estate go?

At the end of last year, Zhang Jindong announced that Suning would focus on its main business in the next ten years, “slashing that should be cut, and that should be transferred.”

Jiangsu Football Club was the first cut taken by Suning. On February 28th, Jiangsu Football Club (formerly known as Jiangsu Suning Football Club) issued an announcement stating that due to the superposition of various uncontrollable elements, the club could not guarantee the continued battle on the field. Operations. Set the embarrassing record of “the Chinese Super League team disbands when they win the championship”.

Jiangsu Football Club is 100% holding of Suning Real Estate.

Suning Real Estate Group Co., Ltd. was established in 2005. As of June 2020, Suning Real Estate has total assets of 88.527 billion yuan, net assets of 14.594 billion yuan, operating income of 1.247 billion yuan, and net profit of 102 million yuan. According to data released by Crane, Suning Real Estate’s full-caliber sales in 2019 and 2020 were 8.93 billion yuan and 17.91 billion yuan, ranking 169th and 134th among real estate companies. ,

Galaxy Property is a wholly-owned subsidiary of Suning Real Estate. It was established in 2000. Zhang Jindong holds 65% of the shares, Suning Appliance holds 25%, and his son Zhang Kangyang holds 10%. Zhang Jindong actually controls 77.5% of Yinhe Property.

As of 2020, Yinhe Property has an area of ​​59.79 million square meters under management and a contract area of ​​79.98 million square meters. Projects under management include commercial properties, technology office properties, high-end residential properties, industrial park properties, public service properties, etc.

Suning Real Estate is the most important asset of Suning Appliance besides Suning Tesco. Under the parent company’s grand strategy of focusing on the main business, Suning Real Estate is regarded as the largest traffic portal for Suning’s smart retail line.

Real estate analyst Yan Yuejin pointed out that with the current acquisition of real estate and retail equity, the scale of commercial real estate development is relatively large. If Suning itself participates in the cooperation, it does not rule out that subsequent real estate business expansion will also be adjusted. In addition, in the current special period, the transfer of equity can enhance cash flow, which is first a positive effect for the company, but in the future, we must also pay attention to whether similar cooperation will affect the business including retail, real estate and other related sectors.

How much more will Suning Real Estate suffer? How will it be positioned within the Suning system in the future? It remains to be seen.

How much is the Galaxy property worth?

The spin-off of property companies to raise funds for listing is a fairly common move by real estate developers in recent years.

As of the end of last year, more than 40 property companies have landed on the capital market, of which about 38 property companies have landed on the Hong Kong stock market, and about 3 have landed on the A-share market.

It should be noted that compared with 2019, investors have become calmer on property stocks, and the market is lowering their valuations. Previously, the first service, Shimao service, KJ Youhuo, etc. broke out at the opening of the market is a wake-up call. But in any case, if the property platform is listed, it will at least be good for the parent company to expand new financing channels.

Suning Appliance chose to pledge or sell the shares of the property management company, rather than seeking to split the IPO, or because of the debt pressure, it needs blood transfusion in the short term.

According to the data from the Enterprise Warning Communication, as of the end of the third quarter of 2020, Suning Appliance’s total liabilities were as high as 299.549 billion yuan, non-current liabilities due within one year were 53.99 billion yuan, short-term borrowings were 49.734 billion yuan, and the ending cash and cash equivalents were only 230.03. 100 million yuan.

In the first half of 2020, Suning Appliance’s revenue was 123.243 billion yuan, down 11% year-on-year; net profit was 784 million yuan, down 69.6% year-on-year, and operating cash outflow was 612 million yuan.

Country Garden Services is a leader in the property management industry. In June 2018, it was spun off from Country Garden Group and successfully listed on the Hong Kong Stock Exchange. As of the end of 2020, it has managed 3277 projects and served 4.24 million owners, with an area under management of 380 million square meters and a contract area of ​​820 million. Square meters, in a leading position in the industry. The annual revenue was 15.7 billion yuan, which is currently the largest revenue in the property sector in the secondary market. In addition, the company also holds tens of billions of cash and equivalents.

Li Changjiang, Executive Director and President of Country Garden Services, once publicly stated that the company may have more than 4,000 projects under management this year, and proposed to achieve a revenue goal of 100 billion in five years.

Country Garden Services, which has a lofty goal and not bad money, started a “buy, buy, buy” model. Last year, it acquired Manguo Kangjie Sanitation Company for 2.45 billion yuan, and Urban Zongheng (elevator advertiser) for 1.52 billion yuan, as well as the smaller Hong Kong Real Estate Industry and Jiakai. Regional property companies in cities and regions.

At the same time that it was reported that the acquisition of Yinhe Property for 3 billion yuan, Country Garden Services also had nearly 4.9 billion yuan to acquire Blu-ray Garbo’s “largest property acquisition case” that has not yet fallen.

If the consideration of 3 billion yuan is true, Country Garden’s offer to Suning has a relatively high premium rate. In contrast, at the beginning of this year Evergrande Property acquired Zhejiang Yatai for 1.5 billion yuan, the latter’s area under management exceeded 80 million square meters; Blu-ray Jiabao, which has an area under management twice that of Yinhe Property, offered only 5 billion yuan—— In the Galaxy property, which covers an area of ​​only 60 million square meters, even if the added value brought by the Suning commercial complex is included, it is worth 3 billion yuan to raise a question mark.

Yinhe Property currently covers more than 200 cities across the country. The projects include commercial complexes (local Suning Plaza), residential and sales offices, industrial parks (towns and logistics centers), office buildings, and public services. There are a large number of projects in Jiangsu Province In other provinces.

Do you think Suning can get out of the debt quagmire? Welcome to write down your opinion in the comment area.

On April 12th, at Huawei’s 18th Global Analyst Conference, Huawei’s rotating chairman Xu Zhijun responded to many hot topics such as “future goals”, “whether to build a car”, and “frequent adjustments to cloud business”.

He pointed out that Huawei’s goal this year is still to survive, “There is hope for survival, and strive to live better.”

Regarding the topic of car building, Xu Zhijun said that after years of discussion, Huawei’s conclusion of not building a car has been discussed. At a meeting in Sanya in 2018, Huawei decided not to build a car. This decision has remained unchanged until now. This year, Huawei’s investment in the research and development of smart auto parts reached US$1 billion.

He said that after discussing with German, Japanese and other car companies, he found that the industry does not need Huawei branded cars, but needs ICT capabilities to help them build future cars. When working with car companies, we hope to create new business models and jointly build some sub-brand cars with car companies to make cars truly face the future.

“We selected three car companies to launch three sub-brand cars, such as BAIC ARC FOX. A series of cars will be launched in the fourth quarter. We have also cooperated with Chongqing Changan and Guangzhou Automobile.”

Regarding the cloud business, Xu Zhijun said that the business model of Huawei Cloud is different and more developed in an independent manner. “When the Cloud and Computing BG was established, it was hoped to integrate servers and storage, but later discovered that the energy of the cloud was consumed in the development process. Now I hope to concentrate on developing the cloud and increase the proportion of software service revenue.”

The following is the full text of the Q&A of the analyst conference:

1. “South China Morning Post”: At present, we have seen many companies deploying in the field of smart cars. Under this circumstance, Huawei does not build cars. Will this strategy stick to it? The payback cycle of the auto industry itself is relatively long. Was this strategy made by Huawei to reduce the pressure of liquidity and the pressure of chip shortages? Can you share more development plans in the field of smart cars and the reasons behind them?

Xu Zhijun: I have been asked this question many times. I have explained the answer to this question in detail in the process of communicating with friends in the auto industry media at the Beijing Auto Show and the Shanghai Auto Show. Of course, I also understand everyone’s aspirations. Everyone thinks that Huawei should build a car. Huawei has the brand and technical capabilities and should build cars. Why not build cars like everyone else? Companies such as Xiaomi are building cars. But I tell everyone that Huawei made this decision after years of discussion. Huawei started to conduct car-related research in 2012, when we established a car networking laboratory under the 2012 laboratory. At that time, there was no concept of smart cars, no concept of autonomous driving, only the concept of electric cars. We first wanted to study the technology needed for electric vehicles.

But as research continues to move forward, the automotive industry is constantly changing, from a simple electric car to an autonomous car. From 2012 to the present, the entire future-oriented car has undergone tremendous changes, and the technology has also undergone tremendous changes, especially after the rise of artificial intelligence technology. It turned out to be a “three-electric” system, and then it was discovered that we were to be a “driver”. In fact, the automatic driving system is to be a driver instead of driving. Later, our research found that all the technologies and capabilities that Huawei possesses are being applied more and more widely in vehicles. We believe that ICT capabilities are becoming more and more valuable for the various technologies and components required for future autonomous driving and electric vehicles.

From 2012 to the present, I have also communicated with the chairman and presidents of all Chinese auto brands, as well as the senior executives of German and Japanese auto companies, and found that the industry needs Huawei more, not the Huawei brand, but Huawei’s ICT Ability to help them build future-oriented cars. Therefore, in 2018, our management team met in Sanya and made a decision: clarify that Huawei will not build cars and help car companies build good cars. This decision has not changed so far.

Of course, as a company in the ICT industry and dealing with the automotive industry, we also hope to create some new business models. Therefore, we will choose some partners for in-depth cooperation, and then we will use the “Huawei inside” approach to support car companies to build their sub-brands, empower some car companies, and truly make future-oriented cars. We have now selected three partners to support them in building their own sub-brands. You may already know that we support the ARCFOX brand created by BAIC New Energy and will soon launch a series of cars for the market. ARCFOX brand series cars will fully combine all of Huawei’s (ICT) capabilities and BAIC’s (complete vehicle) capabilities to give consumers a different experience. We have similar cooperation with Changan and Guangzhou Automobile in Chongqing. We will have options for this kind of cooperation, not too many.

We designed a brand logo called “HI” for the “Huawei inside” model, which stands for Huawei Inside. Seeing the HI logo in the future will prove to be a car built by Huawei and this partner. However, not all vehicles provided by Huawei can be marked with the HI LOGO. Only vehicles using our autonomous driving solution can be marked with the HI LOGO.

2. “China Business News”: Last year, Mr. Xu, you said that the biggest goal is to survive and make a financial report. We see that this year’s financial report has achieved a relatively stable growth. You mentioned just now that the entire external environment this year is still relatively complicated. What are our new challenges or goals this year?

Xu Zhijun: The goal this year is to survive. But this year we hope to have some time to think about the next steps and see if we can live a little bit better. Everyone knows that we are spending time in 2019 and 2020 to deal with the three sanctions imposed by the United States, so there is not much time to think about whether we can really survive in the future and whether we can live better. After so long of inventory and business adjustments, I found that it is still very promising to survive, but we still have to strive to live a little better. So I hope that next year’s annual report conference will be held normally, and the analyst conference will be held normally. Of course, it is the best that it can be held every year. I can meet everyone and you can also see me.

3. IDC: I have two questions I would like to ask. The first is about HUAWEI CLOUD, because we noticed that not long ago, HUAWEI CLOUD made very frequent organizational structure adjustments, and finally changed from BG to Cloud BU with Xiao Xu as the chairman. Finally, Cloud BU is in Huawei’s organizational structure. What exactly is the position of? What changes or adjustments will the corresponding HUAWEI CLOUD strategy have in the future?

The second is about the Kunpeng industry. Not long ago, ARM just released the instruction set of the V9 architecture, and said that V9 is not under the control of the US administrative export license. What is Huawei’s authorization for ARM V9 now? Is it a complete authorization or a perpetual authorization? In addition, in respect of the corresponding Kunpeng industry, how will the future problems of our chip design, production, and foundry be solved? please explain it.

Xu Zhijun: The business model of Huawei Cloud is an online business and a subscription business model. Therefore, Huawei Cloud has always been an independent BU operating end-to-end and relatively closed-loop. When we set up the cloud and computing BG, we hoped to be able to coordinate the operation of servers and storage with Huawei Cloud, but some problems were discovered during the coordinated operation, which instead consumed the energy of our cloud team. So we are now returning the server and storage to let Cloud BU focus on developing cloud services.

We strengthened the positioning of HUAWEI CLOUD BU, which is actually a measure of our company to strengthen software investment. HUAWEI CLOUD invests more in software and has its own industry rules. We hope that it will be more independent and develop more freely to increase the proportion of software and services in Huawei’s total revenue.

Regarding Kunpeng, it itself is an ARM ecosystem, but we have named it in China. No one dares to give us foundry chips now, at least I don’t think it will be solved in the short term. However, we are unswerving to develop Kunpeng’s ecology, and this will not waver. Once Kunpeng’s ecology develops, I believe that other companies will design CPUs. It is just a matter of strength and weakness. This also provides another option for the whole of China.

Regarding ARM V9, whether it is the CEO of ARM or the vice president of marketing, it has been very clear that it is not restricted by the US export control. Unrestricted means that we can carry out normal business cooperation with ARM. , Cooperate as you want.

4. IHS Markit: In recent years, more and more new cars are equipped with interconnection technology. With the improvement of the level of autonomous driving and the addition of various technology companies, more and more rich applications and ecology have been integrated on the car. In the 5G era, cars, as nodes of IoT devices, are interconnected with everything, such as the interconnection of cars and cars, the interconnection of cars and roads, the interconnection of cars and devices, and the interconnection of cars and hybrid clouds. First question, what changes does Huawei think 5G technology and future 5.5G technology will bring to smart cars? Second question, please share the recent progress of Huawei’s smart car product line?

Xu Zhijun: Actually, there are different opinions on how much value 5G has for autonomous vehicles. People who do traffic more hope that the vehicle and the road can be coordinated to realize the automatic driving of the vehicle and give full play to the coordination of the road and the vehicle. In this case, whether 5G or 5.5G, its value is greater. But there is a question. Without 5G or 5.5G, can this car realize autonomous driving? Do you want to achieve autonomous driving?

Another point of view is that in order for a car to realize autonomous driving, it must realize autonomous autonomous driving and cannot rely on others. Just like every normal person of us, all your behaviors are managed independently by you, without relying on others, unlike a blind person who has to rely on a crutch. If a car must rely on 5G or 5.5G in order to achieve autonomous driving, it will be miserable. What if a 5G base station is broken? This puts too high a requirement on the network of mobile operators. The network must cover any place, and it must be ensured that there will be no problems under any circumstances. It must have strong resilience, which is unrealistic.

So from this perspective, whether 5G or 5.5G, it cannot be necessary. Of course, 5G will be better, but it is more of an auxiliary capability. I have always believed that 5G has been politicized and its capabilities have been exaggerated. I once attended a conference and listened to everyone talking about 5G, and the talk was full of enthusiasm, but I couldn’t understand which G they were talking about 5G. Our mobile communication technology has evolved from 1G to 2G, 3G, and 4G every ten years or so. 5G is to evolve one generation and upgrade one generation on 4G technology, which is not much different from the evolution generation of 2G and 3G. Of course, do you say that 5G is better than 4G? That’s not realistic, after all, it was built after the industry has spent ten years and huge investment. Of course, it will be better than 4G. However, it is an exaggeration to say that 5G is the foundation of everything, as everyone said.

Smart car BU is our key investment industry. It has its own sales, delivery and other organizational capabilities. It is our company’s most complete BU except for consumer BG. We have invested more than US$1 billion in the research and development of smart auto parts this year. China now needs 30 million vehicles a year, and there will be more in the future. We believe that even if we only focus on the Chinese market, an average annual income of 10,000 yuan from each vehicle is enough. Of course, Huawei hopes to be a global industry in any industry, not just limited to the Chinese market.

Now every component we make has been introduced to the market and is gradually gaining application. At the Shanghai Auto Show in April, the “Huawei inside” cooperation mode car will provide everyone with an autonomous driving experience in densely-vehicle urban areas. Our team told me: They are the best, able to autopilot without intervention for 1,000 kilometers in the urban area, which is much better than Tesla. You can go to Shanghai to experience it after this meeting.

5.Guardian: Two issues. First, under the sanctions imposed by the United States, Huawei is actually facing a series of supply pressures including chip supply. Now the sanctions will not disappear in the short term, so is Huawei? The future still depends on the reserves prepared before the sanctions? Second, after the Biden administration took office, how did Huawei judge the US sanctions and the future relationship between the US and Huawei?

Xu Zhijun: I think all the customers, partners and people who care about Huawei all over the world are squeezing their sweat for Huawei: How much inventory is there? Our annual report conference has clearly stated that we have no problem meeting the needs of To B customers, but not always.

To cope with this problem, we mainly rely on two points. One is to use these stocks to support us to live as long as possible. For this reason, we focus more on some regional markets and customers. Second, Huawei is a large global purchaser of semiconductor chips and devices. We originally ranked third in the world, second only to Apple and Samsung. We have huge demand. At the same time, China is a huge chip market with nearly 400 billion U.S. dollars in purchases each year. Many Chinese companies are worried that they will be suppressed similarly to Huawei, and they also have similar needs to Huawei. If there is such a big demand, there will always be companies willing to invest, to see if they can find a way that can not only meet the regulatory rules of the United States, but also meet the needs of Huawei and other Chinese companies. We hope that our global partners can do this at a certain time. If our inventory consumption happens to be in line with this, then our problem will be solved. I believe this day will come!

Of course, after the Biden administration came up, we are also paying attention, but we have no illusions about Huawei being removed from the list of entities. We think we will work and live on the list of entities for a long time. We cannot formulate the company’s strategy under assumptions and illusions. Our current overall strategy and specific measures are based on Huawei’s long-term survival and development under the entity list.

6. “Jakarta Global”: Many countries in the Asia-Pacific region have proposed digital transformation plans. From the perspective of Huawei, how do you view the future development of the entire digital transformation in the Asia-Pacific region? What role will Huawei play in this process?

Xu Zhijun: Except for a few countries, the Asia-Pacific region is still relatively backward in terms of digitalization. This new crown epidemic has fully let all government departments, consumers and enterprises see the value of digitalization.

Huawei’s vision is to bring the digital world to everyone, every family, and every organization, and build an intelligent world with all things connected. Therefore, our company’s mission and everything we do is to help the digital transformation of all walks of life.

We have been working in the Asia Pacific for more than 20 years, and Huawei has been working hard to promote the digital transformation of various industries in the Asia Pacific. I believe that this is an opportunity for Huawei. I also believe that through Huawei’s efforts, the digitalization process in the Asia-Pacific region can be accelerated. We can bring advanced technology and digital transformation experience to every country in the Asia-Pacific, as well as every industry, enterprise and government organization in every country.

7.ITR Research: In your introduction, you mentioned 5G and 5.5G. My question is, you just mentioned some visions in 2030, but now many operators and manufacturers are already talking about 6G in 2030. Then I would like to ask what is Huawei’s strategy on 6G?

Xu Zhijun: We believe that 6G should be introduced to the market around 2030. But what 6G is now, we don’t know yet. Our industry hopes that around 2030, like 4G and 5G, there is one thing to contribute to consumers and enterprises, so now we are mainly doing two aspects. First, we work with the industry to work hard to define what 6G is. We may soon release the 6G white paper, hoping to discuss with consumers and all walks of life what 6G will look like in the future. Second, we are doing some basic research and research on cutting-edge technology around the vision and the definition of 6G, hoping to realize the 6G we jointly defined.

Maybe our imagination is limited, or all the industries in the world have limited imagination, and we find that we can’t find 6G application scenarios anyway, then maybe 6G is not needed. If 5G or 5.5G can help realize the scenarios and applications you imagine, then 6G is not needed.

So we may have to wait for the next generation of us, who are smarter than us, or their consumer needs are different, they play differently, and they find that 5G can’t handle their needs. There must be a 6G, which may be the value of 6G. In the past, I discussed with the wireless team, I said that we have achieved 5G from 2G, can this group of people stop doing 6G. But we found that people always come to discuss 6G with us, so we can only organize everyone to study 6G. Therefore, the president of wireless products and I said that we must find a group of young people to do it with us, so that in the 6G era, those of us will retire, because we have no room for imagination and can’t imagine it. At that time, this When a group of people grow up, they can continue to imagine and continue to do it.

So let me summarize our views on 6G: We look forward to 6G, but not necessarily 6G. But we still have to prepare, do research, and invest for the possible arrival of 6G.

8. Nihon Keizai Shimbun: Under the pressure of the United States, how does Huawei maintain cooperative relations with Japanese companies? In 2019, Huawei purchased 1.1 trillion yen in parts and components from Japanese companies. What is the amount in 2020? What about this year? Thank you!

Xu Zhijun: All cooperation between Huawei and Japanese companies is still in a normal state. Our cooperation is mainly in three aspects: First, we provide products and solutions to Japanese operators to help operators serve their customers. Second, we participate in the digital transformation of Japanese companies. Third, we are facing the future together with the Japanese industry to build industries and standards.

Our purchases from Japan in 2019 are about 10 billion U.S. dollars, and in 2020 it will be about 8 billion U.S. dollars, a decrease of 20%. Therefore, Japanese companies are typically treated by unfair trade and non-free trade, because Japanese companies need the approval of the US government to sell a chip or a device to Huawei. This is a typical unfairness and a typical hindrance to free trade. And it’s not just Japanese companies that are affected.

9. DBS Bank: My question is about HiSilicon. Under the pressure of the United States, advanced manufacturing processes cannot help HiSilicon to manufacture chips. I want to know what HiSilicon’s future business model will be?

Xu Zhijun: First of all, any chips developed by HiSilicon now have nowhere to be produced and processed. Secondly, for Huawei, HiSilicon is just a chip design department, not a profitable company, so we have no desire for profit by itself. Now we are raising this team and moving forward as long as we can afford it. Of course, this team can continue to do some research, technology development, and technology accumulation to make some preparations for the future.

“Take long distance water” – survive where there is no water

Every day 11-year-old Nya has to walk barefoot to get some standing water from a shallow lake a half-day walk from her home. Go then go, go and go. Almost all day walking. I have been walking like that for 7 months a year.

But even if she walked this far, the amount of water Nya took back was not much. It was also very hard to get water. Nya had to dig a small hole in the shallow bed of the lake, pick up each handful of soil so that the little remaining water would flow and that hole. I have to wait a long time to scoop a bucket of water into the can. But the water is cool, leaving the water to settle for a long time still does not get rid of the dirt.

The book Taking Long Distance is based on the true story of Salve Dut. Photo: Pham Thuy.

Salva was only 11 years old when she had to flee the war and lost her family. From Sudan, I joined a group of refugees heading east, back to Ethiopia. On the way, they experienced many dangers, from lions to catch people, to groups of robbers along the way.

But there is nothing more terrible than not having water. They crossed the hot desert with little water in hand. A lot of people did not make it out of the desert.
