• Matching: knitted vest + T-shirt + trousers

Speaking of the single item choice for stacking, in fact, the knitted vest is a very good choice. It can be said that it is also a “universal” existence. Whether it is combined with a T-shirt or a shirt, it will look very natural. but Knitted vest and T-shirt The combination of these can not only create a sense of fashion and elegance, but also increase the appearance rate of T-shirts. Moreover, when combined, it will not be so inconsistent. Not heavy. Pair the lower body with a pair of trousers, and tuck the hem of the top into the bottom, which can also give the clothes more layering, which is good-looking and fashionable.

• Design and color: blue + white + printing

Among all the colors, if it can show the tranquil and gentle CP color, then the first thing the editor thinks of is White and blue. Not only can create a sense of fashion and temperament, but also give more wear A sense of refinement, In addition, the blue and white colors also have the effect of cooling down. Visually, they are not very bloated, but they can also create a light effect, and they are very high-end. Yes, that’s right, blue and white are very advanced colors, with a strong minimalism , Even if the effect of printing is added, it will not affect the wearing Beauty , But more accent.

Tips on stacking

• Simple and refreshing colors

Generally speaking, two layers or more are used for layered wear. If you want to wear it exquisitely and beautifully, then the color is really important. However, when it comes to colors that are layered and worn, Same color system, near color system, basic color The best match, so both Not fancy , Still appears very natural. But if you want to wear it brightly, it is recommended that you match it with the basic color. Otherwise, the large-area contrast color will not only make the clothing cheap, but also be less refined. Therefore, everyone should pay more attention to the color.

• The collocation should have a texture and not be bloated

In addition, in the overall collocation, if it is not rumored to be too bloated, in fact, it is OK to put two layers together, just like Vest + T-shirt , The dress is not only western style, but also very visual, and the dress is also good-looking. In fact, it’s very simple in popular terms. Won’t look bloated So, looking at the outfits all day long, the 41-year-old Qin Lan is really elegant and beautiful. Although she looks a little girly, she has a really good temperament.

Different layering styles to wear and match display

• Knitted vest + shirt

Knitted vests can be matched not only with T-shirts, but also with shirts, and are more than matching with T-shirts. Intellectual and capable The effect of the dress is also full of intellectual and accent. At the same time, the contrasting knit vest, matched with a solid color shirt, looks very elegant visually, and it is not fancy to wear. The lower body is matched with plaid trousers, the overall match Ultra-reduced age Oh.

• Leather + Cardigan Jacket

In stacking, leather clothing is also a single item that can often be seen. It is combined with suit coats and other outerwear. Charm Still fashionable. Moreover, the contrasting color coat and the leather coat are not only restrained from the hostility, but also more visually. Textured , And matched together, it also weakens the old-fashioned feel of leather clothing, and it looks cool and fashionable.

The feudal power system established by the Qin dynasty laid the basic foundation for the political structure of later Chinese feudal dynasties. In addition, the policies and systems that divided the country into districts, districts and hukou at that time also had a great impact on the development of the next generations. When posterity looks back on Qin Shi Huang’s journey to unify China from a modern perspective, they must also recognize that this glorious path has timeless inspirational power. The Qin people were originally just horse breeders for the Zhou royal family, then rose to the status of vassals in the Zhou Dynasty (795 BC-771 BC). So why is it that Qin Shi Huang – the king of an ordinary vassal state – was able to unify the six countries and become one of the greatest emperors in Chinese history? Historians say that the secret lies in the weapons of the Qin army: The Qin army possessed powerful weapons, far superior to other vassal countries. Prior to the unification of the six states, the kingdom of Qin was a prosperous vassal state through the reform of the “Transformation of Shangyang” (implemented twice in 356 BC and 350 BC). This reform greatly increased the productivity of Qin society and promoted the development of weapons to a certain extent. Experts said that in the excavation sites of the terracotta army, bronze weapons account for a very large proportion. While the forging and metallurgical technology of the other vassal countries were still quite backward, the state of Qin – a country that valued weapons – had made great progress in this field. Earn copper The bronze swords unearthed next to the terracotta warriors are the clearest evidence of the advancement in forging and metallurgy techniques of the Qin Dynasty. After research, it was found that these bronze weapons were superior to the other six vassal states, the main reason being that the Qin state at that time had mastered the method of making alloys. Their craftsmen also tried to apply the proper proportions of alloys to the military field. Some experts believe that the ratio of copper to tin in the weapons of the Qin army at that time was very reasonable and scientific, especially the tin content was much higher than before, helping bronze weapons. of the Qin army was much harder and sharper. It can be seen that these swords not only have anti-rust treatment, but their length is also about 20 cm longer than swords in other countries. Qin Crossbow The second most notable weapon is the Qin crossbow. The Qin crossbow was developed by the Qin state on the basis of the bow and arrow, but its damage is far beyond the ordinary bow and arrow. Conventional bows and arrows have a limited range, low accuracy, and can only shoot one shot, so soldiers are easy to fall into the attack range of the draft. To improve this problem, the Qin crossbow was born. Through a series of design reforms, the Qin crossbow’s hit rate has been greatly improved. Furthermore, crossbow design parts and components are also standardized and uniform across the country. As a result, when a weapon is damaged, it can be quickly replaced or repaired to immediately return to combat. In addition, the Qin crossbow also has a user-friendly design, minimizing the possibility of soldiers injuring themselves. Three-sided arrow Another notable weapon is the three-pointed arrow that the Qin army used. Thanks to the excellent craftsmanship of the Qin Kingdom craftsmen, this arrow has extremely strong penetrating power. It possesses a unique three-sided design that reduces drag to a minimum after firing. This is also a weapon that other vassal countries do not have. Precisely because of possessing weapons much more sophisticated than those used by the armies of other vassal states, New historians argue that the Qin Dynasty possessed “divine objects” that should not have existed at the time. In addition, the principle of standardizing the manufacture of weapons throughout the territory of Qin also helped soldiers improve their combat capabilities. It can be seen that at that time, the Qin Dynasty was ahead of other vassal countries in both economic and technical aspects. It is not surprising that the Qin Kingdom became the ultimate victorious state and unified China.

The US has a rather slow 5G rollout. Photo: NetEase Since the advent of 5G technology, US carriers have been slow to deploy 5G networks. The main reasons are limited spectrum resources available for 5G, cumbersome deployment of 5G devices, and lack of killer applications for 5G services. The media often uses words like “fast” to describe 5G speeds, but the speed of 5G wireless network rollout in the US has nothing to do with the word. Over the past three years, the prospect of 5G wireless networks has been the focus of major media reports. But for most Americans, the real 5G that can achieve the desired effect is yet to emerge. Although all the major wireless carriers in the country claim that their 5G services have covered the entire US, industry analysts argue that this so-called 5G service is not much different from the US. 4G. According to market research firm Evercore ISI, most Americans may not enjoy 5G service that is significantly faster than current wireless communication networks. “Overall, it is expected that between late 2021 and late 2023, truly better 5G services will cover two-thirds of the US population,” said James Ratcliffe, an analyst at Evercore ISI. The first batch of mobile phones that support 5G networks was launched in mid-2019, according to Ratcliffe, in the most optimistic scenario, wireless network operators will be able to provide “real” 5G services to 2/3 of the US population in the next 30 months. Meanwhile, the first mobile phone to support 4G network was released in 2010, and the US 4G network was basically rolled out 18 months later. Analysts, academics and former industry executives say a combination of factors has resulted in a relatively slow rollout of 5G networks in the US. Some of these problems are related to network infrastructure: high-speed network transmission frequency bands and signal coverage are limited. Moreover, the new network equipment that needs to be on the shelves to deploy 5G networks is relatively cumbersome. In addition, many new devices are not made in the US, so the time to purchase the device will be longer. Industry observers also point out that the current 5G network still lacks breakthrough applications, and cannot stimulate user demand and promote the spread of services such as mobile video in 4G networks. John Roese, chief technology officer of Dell Technologies and a former executive at companies like Huawei and Nortel, said that although wireless operators have recently invested billions of dollars in 5G networks, when Because their revenue in 5G-related businesses is not stable, they may not be able to accelerate the construction of new networks. According to Mr. Roese, wireless network operators have had disappointing returns when investing in 4G networks. He said that the main beneficiaries of 4G networks are technology companies that provide applications and other services through the network. “So wireless operators are very cautious about this.” Limited frequency range Photo: Sina To meet the large traffic that 5G networks have to transport, carriers need to open “highways” for data. The spectrum is similar to the real estate that the government grants to carriers through auctions to build highways. The more land they have, the more lanes they can open for faster 5G and easier access. Currently, 5G networks mainly transmit data through low-band, mid-band and high-band. High-band (mmWave) aka millimeter wave has the highest data transfer rate and largest bandwidth, but the smallest coverage. Low band has wider coverage but slowest transmission speed. Finally, the mid-band is considered to be the balance between coverage and transmission speed. Companies like Verizon, AT&T, and T-Mobile all claim that their 5G networks now cover more than 200 million Americans, enough to meet US demand. However, most of these networks rely on low-band radio waves to complete coverage, and network transmission speeds are limited. Wireless network operators are currently focused on capturing mid-bands and have invested a lot of money in recent tenders for these resources. But the main problem facing these companies is that most of the mid-band bands have been occupied by US government agencies and other agencies, mainly for military communications and meteorological services. . Until now, wireless network operators could only use a fraction of the mid-band resources. US government agencies are also aware of the lack of mid-band resources. Earlier this year, the US auctioned a total of $81 billion in mid-band licenses, and plans to hold another auction this fall. When operators were preparing to roll out 5G nearly 10 years ago, they generally believed that 5G networks would primarily use high-frequency radio waves, said Stefan Pongratz, analyst at Dell’Oro Group. . This portion of the spectrum resource is essentially unused. But Pangraz says that rolling out a 5G network using millimeter waves requires building more base stations, which will certainly take time to increase deployment density of base stations. He said that until recent years, the US turned its attention to mid-band radio waves as a way to roll out 5G networks faster. Where is the profit point? Photo: Justin Hall Comics Brian Kelley, an associate professor of electrical engineering at the University of Texas at San Antonio, said the lack of disruptive applications is another major factor hindering the rollout of 5G networks. Mr. Kelly, who was an engineer at Motorola, said: “It can be said that this is the biggest factor that can stimulate the speed of 5G deployment.” According to analyst Craig Moffett, the 3 main advantages of 5G networks are faster data transmission (100 times faster than 4G), support for a large number of simultaneous connections, but also significantly improved response speed between devices. device is connected. “There isn’t a single revenue model that can combine these three advantages. It’s not even clear if consumers are willing to pay more for faster video downloads,” Moffett said. Moffitt said that because 5G networks can seamlessly connect sensors and other IoT devices, companies will likely be the first adopters of 5G services. He said that 5G networks “can be considered the next generation of Wi-Fi wireless networks, which are faster, more secure and can connect more devices”. But Moffett said the question is: “Will wireless operators build their own 5G networks for enterprises, or will the enterprises themselves deploy them?” This is important, he says, because if businesses choose to deploy their own 5G networks, wireless operators may lose the associated revenue and not be able to invest more money in building infrastructure. 5G layer. Device problem Currently, in the world, there are 5 companies that have successfully produced network equipment for 5G, none of which is in the US. Photo: Sina 5G networks are very different from 4G, in part because 5G networks need to transmit data at a higher frequency band. This means that upgrading 5G networks requires different technologies and devices. Evercore analyst Ratcliffe says installing new equipment can require finding a suitable location, obtaining the right permits, and even digging up roads and laying fiber optic cables to transfer data at high speeds between base stations. Gazzola, chief executive officer of Atlanta-based infrastructure company Bennett & Pless, said it is expected that by 2022, the construction work needed to bring wireless communication networks to 5G standards will increase. . However, the epidemic and technical obstacles have delayed progress. Equipment availability is also a common issue faced by wireless network operators. Dell’s Rose said that when 4G was first introduced around 2010, there were about a dozen technology vendors offering wireless networking equipment, including Canada’s Nortel and America’s Motorola. Today, there are only five major players in the global network equipment market: Nokia, Ericsson, Samsung, ZTE and Huawei. “Two in China. One in Finland, one in Sweden and one in Korea.” These suppliers are all located outside the US. Worse still, 5G network equipment requires computer chips while the chip industry has been struggling recently to cope with supply shortages.

Qin Shi Huang is always looking for the way to immortality for his life, but unfortunately still can’t find a way. So he decided to build a magnificent palace underground and that is also the tomb after his death. One of the mysteries surrounding the tomb of Qin Shi Huang discovered by scientists is the extremely large amount of mercury inside. Many conjectures say that the amount of mercury in the underground palace can be up to several tons, even hundreds of tons, which is why grave thieves cannot enter. Many questions arise, what is the real function of this mercury? Is it for anti-theft as inferred? According to research on the history before the time of Qin Shi Huang, scientists did not find mercury to have much effect, and only detected a small amount of mercury in the type of mummification. The original hypothesis was that mercury could act as an anti-corrosion agent. But when discovered in the underground palace, a relatively closed insulation layer is formed due to the function of mercury. Many other opinions say that Qin Shi Huang used mercury to prevent theft. However, when returning to the history of the time when Qin Shi Huang unified China, people’s understanding of the uses and harms of mercury was not known. It wasn’t until the Han Dynasty that people began to know that mercury contained toxic substances. The river of mercury inside the tomb. The final conclusion was reached, the reason why Qin Shi Huang used a large amount of mercury in his tomb to prevent his body from rotting due to its anti-corrosion function. With the large amount of mercury in the tomb, his coffin was left in the riverbed for a long time while still remaining remarkably intact. Maybe Qin Shi Huang still holds the hope that one day in the future, he will wake up. This is even more important than theft prevention. How deep is the tomb? The most recent survey of archaeologists has shown that the underground tomb of Qin Shi Huang is 260m long from east to west and 160m wide from north to south. The total area is 41,600 m2. This is the largest mausoleum in the Qin and Han dynasties, its size is equivalent to 5 international football fields. Later archaeologists used a drill and proved that this tomb was designed vertically. Sima Thien once said, the length of this tomb is longer than 3 rivers combined. According to the book “Rites of the Han Dynasty”, the end of this tomb is immeasurable. That proves that the tomb has reached the deepest possible depth with the level of science and technology at that time. But how deep the tomb really is, no one has the exact answer. The Mystery of the Terracotta Warrior According to unofficial records, Xiang Yu – the king of the Zhou state, who overthrew the Qin empire, ended up perishing at the hands of the “Terquered Army”. He was eliminated by five cavalrymen on the banks of the Wujiang River. They were Qin soldiers from the Guanzhong region and were used as prototypes for Qin Shi Huang’s Terracotta Cavalry. Does the tomb have “9 floors of hell”? Looking down from above, you can clearly see, the pyramid is square, so the Americans call it “dwarf pyramid”. Paradoxically, the inverted pyramidal shape of the mound seems to coincide with the saying “9 floors of hell” and this is completely unique in the world. Qin Shi Huang is a freak, this mystery can only seem to be revealed by archaeological discoveries. How many entrances does the Tomb of Qin Shi Huang have? According to “History of Sima Qian”, a great history book written by Sima Qian: When the emperor died, he was taken to the tomb. After that, the main door was closed and the outer gate was also completely closed. All the craftsmen were buried with the emperor. “This proves that the tomb has three gates: the outer gate, the central gate and a secret gate. It is believed that the middle gate was locked automatically to prevent any intrusion from the inside or outside. And the three doors are placed in a straight line.”

Bun rieu – an indispensable dish for Hanoians. (Photo: Internet) In the heart of the old town, people still hear about a vermicelli shop located at the beginning of a small alley with a very strange name: “hate vermicelli”. In fact, the shop still has a very carefully stamped signboard over the decades “Yen – special bun ziu burden – welcome”. But because the shop is located next to a small relic, there is a stele “Ingrained hatred”, so people who are used to eating here call it “bun ziu hate” as a way to distinguish it from other noodle shops. What makes this special name is because this shop is located next to the monument of the stele “Engraved with hatred”. (Photo: Internet) Called a shop, but in fact, this is just a small vermicelli with a pot of broth, a few utensils and ingredients for making vermicelli. When guests arrive, they arrange plastic chairs to sit, using higher plastic chairs to make a table to place a bowl of vermicelli. Photo: Internet Bun rieu here still only includes familiar ingredients such as crab, fish cakes, beans… Each bowl of vermicelli noodles costs only 20,000 VND. Besides, this “hate” vermicelli restaurant also sells snail vermicelli, beef vermicelli (with beef) for 30,000 VND, and if anyone wants to eat a full bowl, it will cost 40,000 VND. Photo: Internet Photo: Internet Photo: Internet The bowl of vermicelli noodles is always full, eating one bowl is full. Even the owner is very enthusiastic and welcoming to customers. Students who come here to eat also get a discount, typically a full bowl is reduced to 10,000 VND, only 30,000 VND/bowl. “Vun ziu hates” every bowl is full, both crabs and vermicelli. Add some raw vegetables and chili peppers and it’s delicious. Customers usually don’t come in droves for a while, but from one turn to another, from early morning until noon, there are almost always people coming. Every day, the shop is usually open from 7 a.m. until early afternoon to clear the goods. If it’s late, clean up late, leave early. Photo: Internet One morning, wake up a little earlier than usual and stop by to make a bowl of “bun ziu hate”, you will see that Hanoi has many interesting things!

Galbi – grilled ribs. Galbi is the common name of grilled ribs in Korean cuisine. Galbi is usually beef or pork ribs soaked with soy sauce and then grilled. Bulgogi – grilled beef. Bulgogi is marinated with soy sauce and sugar, which makes the dish fragrant and softer. Beef bone soup, also known as seolleongtang, is made from hardened beef and bones. Samgyetang – Chicken ginseng. Every year in the history of Korea there are 3 hottest days called Chobok, Jungbok, Malbok. During these hot days, ginseng chicken dish is wanted by many people because it has the effect of dissipating the heat. Sindubu-jjigae is a spicy stewed tofu dish. Soft tofu is made with soaked soybeans, also known as “beef in the vegetable garden”. Naengmyeon – cold noodles. This noodle dish is used in a large bowl, has a strong smell, and has a sweet and refreshing taste like dissolving the heat of summer. However, this is not the reason why this noodle dish is rejected in the cold season. Japchae – Burmese mixed with Korea. The main ingredients are made from vermicelli and seasonally arranged vegetables (usually sliced ​​carrots, onions, spinach, mushrooms) and meat (usually beef). Korean people use sesame oil (sesame oil) to fry. The main spices of this dish are soy sauce and chili. Gimbap – Seaweed roll rice. In terms of shape, Gimbap is like Japanese Sushi, but is processed larger and inside there are many different types of foods creating unique colors. Bibimbap – Mixed rice. Normally a bowl of bibimbap rice must have at least 7 colors: white rice, egg yellow, green vegetables, brown meat … Common vegetables are chopped cucumbers, carrots, vegetables. bina, the price has been outrageous. Kimchi is a dish that should not be missed because this is a dish that Koreans respect and indispensable in daily meals. Not only is the country’s traditional dish, kimchi is also a favorite dish for many tourists.

Russian long-range radar system. “It is known that the lower the frequency range, the greater the penetrability of the waves, so our radar shooting can be done not only through clouds, fog but also under foliage and camouflage vehicles. . Accordingly, if a forest can be optically photographed under ideal conditions, our radar will be able to penetrate the foliage and be able to see any objects in the scanning area. ” Said Ilya Kuzmin, engineer of the Institute of Micro Devices and Control Systems called LN Presnukhina of NRU MIET. With the help of radar, it is possible to generate images not only of the visible surface but also to give its extensive interpretation, determining, for example, the state of soil and vegetation. By attaching the platform to an aircraft or drone, it is possible to capture volcanic eruptions, earthquakes or collapsing buildings. The new radar-controlled aircraft will provide images from which not only can the scale of the disaster be assessed, but also the detailed examination of objects. This development could also serve as the basis for satellite radars and applications in both scientific and military research. In the future, the satellite could carry out radar surveys on large areas of the country and around the world. The new radar can also be useful in agriculture for tracking crop growth, soil conditions and even fruit ripeness. During ice exploration in the Arctic and Antarctic conditions, the radar will determine the thickness of the ice and suggest routes that the icebreaker can take. In addition, the new radar system can help monitor the pipeline and oil pipeline. Radar is not, of course, an instant image projection camera; These are the reflected signals that are digitally recorded on a hard disk and processed by software, explains Ilya Kuzmin. At the same time with the revelation of new radar technology, Russia has also put into service the first unmanned radar system to monitor all flight activities in an area of ​​300,000 km2. General Andrei Koban, Commander of the Radio Technical Force of the Russian Aerospace Forces, said that each system is equipped with 20 radar modules. Each module can scout an area with a radius of 450km. “Integrated radar system with 20 modules, automatically control the aircraft’s operation over an area of ​​300,000 km2”, said General Koban. In addition to airspace control, the Nablyudatel radar is responsible for navigation, providing flight routes for aircraft that pass through the area in which it operates. General Koban also affirmed that this is the first radar system in history that can operate fully automatically without anyone participating in the control. Currently, Russia has deployed at least two Nablyudatel complexes to areas with the highest and most complex air traffic traffic.

Chinese Vice Foreign Minister Qin Cuong. (Photo: Xinhua) Chinese Deputy Foreign Minister Qin Cuong is said to be preparing luggage to go to Washington to replace Cui Thien Khai, a veteran diplomat who is about to finish his job after more than 8 years in the position. The information that Mr. Tan Cuong moved to the US appeared earlier this year when Mr. Thoi, 68 years old, was about to retire. The reports say that Cui is being asked to work a few more months for Beijing to consider how to deal with the new US administration of President Joe Biden and to choose Cui’s successor. Only 55 years old this year, Mr. Tan Cuong is the youngest of the four deputy foreign ministers to assist Chinese Foreign Minister Wang Yi. Moving up from the position of Head of the Reception Department, Mr. Qin was in charge of the schedule of Chinese President Xi Jinping during all state visits and was responsible for organizing talks, receptions, and events. Other receptionist activities. Mr. Qin is repeatedly seen accompanying Xi on tours, including visits to the US in 2015 and 2017. Articles say that Mr. Tan’s meticulousness in managing and arranging visitors Inviting to help ensure few incidents occur outside of a diplomatic scenario when Xi visits countries. Mr. Qin was also a spokesperson for the Ministry of Foreign Affairs of China, praised by Chinese netizens for his tough and straightforward speech. With that style, Mr. Qin is often indecisive in speech that harshly criticizes the US and the West. The official’s tough statements come before the emergence of “warrior diplomacy”. In a 2014 press event, after then-US President Barack Obama ended his visit to Asian allies and reportedly turned down Beijing’s invitation, Mr. Qin was known for his statement that China Quoc will remain there and hold his stance whether the US president visits or not. “We would welcome (Mr. Obama) to visit China, but being friendly to the US in exchange for a visit is the last thing Beijing will do and the US should give up all delusions,” said Mr. Tan, during the second relationship. The country is not as tense as it was during the Trump era. In the current role of deputy foreign minister, Mr. Tan is in charge of both EU affairs and relations with each member of the bloc. He worked in the Chinese Embassy in London from 2010-2011. Mr. Qin is considered the “rising star” of Chinese diplomacy, especially trusted by Mr. Xi for his achievements on the diplomatic front. A cultural attaché at the Chinese embassy in Mexico City and formerly with the Americas Department of the Chinese Foreign Ministry said that Mr. Qin was one of the few candidates selected to fill the ambassadorial positions. in the US, UK and United Nations. The attaché said that it was not known whether Mr. Tan’s lack of experience with the US would be a plus or a minus point. “The delay in Beijing’s delay in bringing Mr. Qin to Washington could be a sign that no official decision has been made yet, given the fact that Mr. Qin rarely engages in Chinese-US interactions.” in addition to arranging Xi’s two state visits to Washington, “the diplomat said, who did not want to be identified. “The current ambassador and former ambassadors of China to the US are both senior and experienced officials, possibly the Director of the North American Department or a veteran of Sino-US relations, but he Qin is not like that and his appointment as an ambassador to the US will disrupt tradition, “the diplomat said. If Mr. Qin is to truly become Beijing’s most important relations manager, this would be a change in Xi’s overall thinking about relations with the United States and how the leader is, the diplomat said. convey the message. Appointing Mr. Tan to Washington should also not be understood as downgrading relations with the United States, because Mr. Tan still holds the rank of deputy minister, the diplomat said. Beijing’s appointment of Zheng Zeguang, who worked in the US for many years, as head of the embassy in London, is seen as a sign that China is looking to turn diplomats around. Minh Bao , the Chinese-language newspaper, speculates that the appointment of Mr. Zheng and possibly Mr. Qin suggests that knowledge and experience may no longer be the most important factor, but the focus is now on those who have witnessed. demonstrated the ability to implement policies and directives from Beijing. Drew Thompson, a former Pentagon official and now professor of public policy at the National University of Singapore, told reporters that Cui, the outgoing ambassador, has acted as a diplomatic buffer amid US tensions – Trung surged in the past few years. “It is difficult to find anyone who underestimates Mr. Cui in Washington DC,” Mr. Thompson said. He wondered whether Mr. Qin, a man who often had a tough tone and had a close relationship with Xi, was judged like this in Washington, during a period when the relationship continued to deteriorate.

Qin Shihuang was the first emperor of China with a history of five thousand years, unifying six vassal countries, unifying currencies, unifying documents, contributing to building the world famous Great Wall of China, and Of course, the large and large population of Qin Thuy Hoang tombs. The tomb of China’s first emperor is at the northern foot of Mount Lishan, 5 kilometers east of Lintong district, Shaanxi province, northern China. Built between 246 BC and 208 BC, spanning 39 years, this is one of the largest, most exotic and richest emperor tombs in the world – home to a multitude of treasures and mysteries, among which there are reasons for the existence of 8,000 human statues of terracotta army. Located in Shaanxi Province, China, Qin was discovered by accident in 1974. Since then, many magical legends have been aroused around this colossal colony of mausoleums. According to historical records, many different palaces were built in the Qin Mausoleum, displaying many strange treasures. A large number of burial pits and tombs of different shapes and meanings are also distributed around the Qin Mausoleum. With undeveloped technology, we can only see “the tip of the iceberg” in the Qin Shihuang mausoleum complex: There are 8000 warriors and terracotta war horses. However, that much knowledge is interesting and surprising enough for historians and archeologists. Over the past two thousand years, many grave thieves have tried to infiltrate the Qin mausoleum, but none of them succeeded. The reason is that the tomb of Tan Thuy Hoang was designed with many sophisticated underground traps during the construction process. These are the traps in the Qin Shihuang mausoleum that researchers discovered so far: First trap: Mercury During the survey, archaeologists also discovered that the concentration of mercury in the ground around the Qin Shihuang Mausoleum was actually very high. In addition to the presence of an antiseptic, these mercury are also highly toxic. The second trap: The crossbow trap Many Chinese historians have written about this sophisticated and dangerous trap in the Qin Shihuang Tomb. In the book “History” of the historian Sima Qian there is a specific record of this type of trap. He wrote: “The statue of the crossbow, possessing a fake armament of musk chi”. That means, for any intruder that destroys Qin King’s sleep, will suffer the most frightening consequences when the crossbows are stretched, ready to destroy the stranger with hundreds of sharp arrows. Image of a Qin crossbow. The famous Qin crossbow not only shoots farther than the bow and arrow, more damage, but also has a higher hit rate. This weapon is made of mulberries, the arms of the Qin crossbow are usually 60-75 cm long, 4-5 cm wide. Since the entire body of the crossbow is composed of dense leather straps, this not only enhances the structural strength of the bow’s stem, but also has excellent toughness and elasticity. Of course, whether the crossbow can function after two thousand years is not yet known. Third trap: Sand trap The tomb of Qin Shihuang is also equipped with sand traps. Once quicksand is dug by grave thieves, it can turn into a grave of their own. The quicksand traps system has been sophisticatedly “posted on the battlefield” as follows: When entering the Qin Mausoleum, tomb thieves will see “a trap”. Tomb theft will think that is the path leading to the treasure and try hard to dig. However, instead of the entrance to treasure, it was the burial ground of greedy people. Because the amount of sand in the trap will fall, burying strangers. The fourth trap: The fire trap Scenes like this will appear a lot in recent tomb theft novels, biogas and flammable substances appear in the aisle of the tomb, the tomb thief will be burned down the moment it opens. The same thing also appeared in the tomb of Tan Thuy Hoang. This shows that Qin Wang attaches great importance to his fall asleep. Fifth trap: Curse Although it is hard to believe, after the completion of the Qin mausoleum, it is said that if a person daring to touch the tomb of the Qin Shi Huang Mausoleum, harass the Qin King’s sleep, that person will be killed by thousands of terracotta warriors and war horses Frantic revenge mausoleum. Army image of nearly 10,000 human statues in the tomb of Tan Thuy Hoang. Is this the meaning of existence of thousands of terracotta warriors and war horses placed in giant tombs? After 3 large-scale archaeological discoveries, this army of nearly 10,000 soldiers was discovered in the tomb of the Qin King. All have the size and shape of ordinary people, especially, with completely different faces, no one resembles anyone. And historians always wondered, what does the meaning of the ten thousand soldiers in Qin Mausoleum mean? Does the curse that exists in Qin-mausoleum partly tell the meaning of this army? Even so, the curse is not easy to believe, but can scare the grave thieves. This method of using the curse is considered the most frightening and most haunting.

The historically famous Emperor Qin Shihuang was an emperor who unified six vassal states. Accordingly, China became a powerful empire with a large territory. After unifying the country, Qin Shihuang implemented a number of measures to make China more powerful and richer. Among these, Tan Thuy Hoang has achieved great achievements in the construction of the road system for convenient transportation and development of trade. Specifically, King Qin ordered the construction of many large roads spreading throughout the territory of China and taking the capital capital Ham Duong as the center. Accordingly, many major routes radiate from Ham Duong in different directions to remote areas of the country. These roads were built under the reign of Tan Thuy Hoang and are large in size so that many vehicles can pass through at the same time. Some studies by experts show that Tan Thuy Hoang built about 6,800 km of roads in about 10 years. Thanks to these big roads, the movement of people as well as sending letters from different regions to the capital city is more convenient, shortening the time compared to before. Along with that, the road system helps to develop trade, the activities of buying and selling goods, agricultural products … take place more efficiently. As a result, the economy has made great development. After the death of Qin Shihuang, the road system was used in many centuries to significantly change the lives of the Chinese people in feudal times.

Source of Korea Times commented that LG currently does not have too much experience in the field of cars or electric vehicles. The selection of the Apple Car electric vehicle project is for the Korean giant to demonstrate its transformation efforts.

The deep relationship between Apple and LG is said to be an important factor in bringing these two corporations to a cooperation agreement in the automotive sector. Apple is currently a partner of many LG subsidiaries such as LG Display, LG Chem, LG Energy Solution and LG Innotek.

In addition, LG has played a role in supplying engines, battery packs and components for electric vehicles of General Motors and Tesla. Magna has many years of experience in providing technology solutions for many car manufacturers.

Representatives from LG currently declined to comment on the information Korea Times.

Since the beginning of 2021, Apple is said to have been looking for partners to research and manufacture self-propelled electric cars. Initially, Hyundai and Kia were the first two names to sit at the negotiating table with Apple and were unsuccessful. Then, it was reported that Apple had contacted six Japanese carmakers, but the results were not better.

Since the company’s energy management system (Energy Management) came into operation in 2014, information on equipment operation and energy consumption has been reviewed and evaluated comprehensively. In fact, the plant’s lines are invested in many stages, asynchronous, so it is necessary to research to have appropriate solutions, especially related to synchronous lines and energy consumption, positive pressure. to use new techniques and technologies to use energy economically and effectively, improve the life of equipment and reduce costs.

In addition to internal issues such as promulgating regulations and instructions related to operating and using equipment to save energy, raising the user’s awareness into a cultural feature, the Company has implementing many renovation projects. Typically the major improvements are as follows:

Water supply system improvementPreviously, using only one upstream station and mixing pumps with different characteristics, causing energy loss, often having problems in the pump system and not meeting production needs well.

The renovation project is divided into 2 independent stations and connected in series: the upstream station reduces the pressure and increases the flow to supply part of the transmission line and the booster pump station is used for the required equipment. higher pressure. Each of these pumping stations includes a number of pumps with the same output and ensures the characteristics of parallel-connected pumps are equivalent and each station has 01 inverter pump as the main driver to automatically control the remaining pumps according to the applied pressure.

Always maintain the desired pressure in each area and optimize power consumption when demand changes to reduce power consumption in this area. The equipment’s age has also been markedly improved.

Install the inverter that controls the fan motor speed: To replace the flue air pressure control system with the previous inlet throttle.

When the power consumption is in proportion to the rate of 3 with the change of speed: N1 / N2 = (n1 / n2) 3 should show that in addition to the ability to respond to the fast system, the power consumption is very saving. After replacement, it was verified that power consumption decreased by more than 20% compared to before.

Replaced Russian 20/8 Piston Air Compressor: By Ingersoll-Rand R160 inverter controlled air compressor from USA to help adjust pressure as desired and save energy consumption.

Installation of low voltage compensation system: In addition to 6KV compensation, automatic compensation cabinets are installed for low voltage distribution stations; directly install compensation cabinets for AC motors> 22 KW, right near where the engine works; help to improve quality Electrical Power for the gear and reduce losses, reduce current through the switch for direct compensation motors.

Install the LEDs: For use areas with different requirements 150 lux, 200 lux, 300 lux, 500 lux, and have separate switches that are clearly communicated and specifically assigned.

Replace the oven ceiling with new materials: Previously made of heat-resistant concrete, there was a large heat loss with the temperature measured above 100 degrees C, the Company replaced with a new material with ceramic fiber, the temperature dropped to around 70 degrees Celsius and ensured ensure better life during work

Installation of aeration systems for filter towers: Helps to dispel the debris that clumps up that previous backwash is ineffective. Helping the filter towers always in effective working conditions, reducing pump power consumption due to reduced filter pressure and increasing the time to change filter material after 3 years instead of yearly as before, reducing production costs.

Renovation of replacement materials for cooling towers: The previous material is PVC with a short working time that must be replaced every 3 years and has a lot of dirt, reducing the heat exchange process is replaced by a Composite material (FRP) with better heat resistance. , no fouling and Splash Bar design to create turbulent and splashing flow for better exchange and cooling (the previous temperature through the Tower only decreased from 5-7 degrees, raised to 10-12 degrees C), reduce the power consumption for the cooling fan and the service life of the material is more than 10 years.

With a series of technical solutions above, energy audit results in 2018 show that energy management activities in Vietnam – Singapore Steel have achieved quite good indicators, power consumption and FO oil have both decreased. Specifically for electricity, from 2015 to 2020, auxiliary power will decrease from 21.70 Kwh / ton to 20.48 Kwh / ton of product; Electricity for production decreased from 97.97 KWh / ton product to below 86.79 KWh / ton of product. FO oil for billet baking in 2015 to 2020 will decrease from 32.50 liters / ton of products to 31.29 liters / ton of product.

Sharing experiences in energy saving activities at the Conference of the Ministry of Industry and Trade

Energy management activities, research and application of science, technology and new technology in the production process help reduce consumption and optimize expenditure. From there, it will contribute to improving productivity, product quality, reducing costs and increasing product competitiveness in the market.

Moreover, this also shows the sense of responsibility, increases creativity and professionalism in the work of the technical team of the Company. Using energy economically and efficiently is a very unique culture of NatSteelVina and this activity has been shared at a number of specialized conferences of the Ministry of Industry and Trade.

The company will continue to uphold its existing results and traditions to grow and prosper.
