Suddenly, Haier Zhijia has been renamed for two years.

What has Haier Zhijia done in the past two years? What have you gained? On June 21st, Haier Zhi used “a letter from the family” to initiate a cross-time look at each other.

In my opinion, this is not only a confession letter, but also a farewell letter.

What Haier Zhijia confessed is the future. Haier Zhijia wrote the idealized life picture of “smart home, new residence” between the lines; farewell is the past. Haier Zhijia, which has entered the new track of the scene ecological brand, has already cooperated with the “home appliance brand”. The label waved goodbye.

Confess the future: let users live what they want

“Once, I was just an object in your home, and now I am integrating into your family life; once, as long as I have good quality, you will be satisfied, and now, your life wisdom is my attitude.”

A family letter, with a few hundred words, tells the changes in the lifestyle of a generation. In the eyes of the outside world, the home appliance industry has long been a red sea. With the upgrading of demand and the iteration of technology, where will the industry go in the future? “IoT Smart Home Ecology” may be the answer.

In Haier Zhijia’s understanding, “allowing users to live what they want” is the most sincere confession about the future.

In the new era, users no longer need a home appliance, but a complete and convenient smart scene. In an interview with the media, Li Huagang, president of Haier Smart Home, said: “We study the best kitchen appliances and the best refrigerators in the world, but today users want more than just this, but a perfect home.”

This is also the innate mission of the scene brand Triwing Bird. From the actual experience, based on the industry-leading rich smart network devices, Triwing Bird can provide the most comprehensive whole-house full-scenario solution, and the most professional smart home whole-house renovation/bureau refurbishment service.

For example, the Triwing Smart Kitchen includes smart food scene solutions for the whole process of eating, buying, storing, preparing, washing and changing. In the past, the refrigerator was nothing more than a container for food storage, and the refrigerator in the Triwing Smart Kitchen can tailor a complete set of healthy meal services such as customized diet plans and provide healthy traceable ingredients for users, with a new identity as a “family food butler” Integrate into the user’s real life scene.

At the same time, Haier Smart Home works with all walks of life to serve user needs in an open and cooperative manner, ensuring that smart scenarios can be freely customized and continuously iterated. For example, there are not only washing machines and dryers on the balcony, but also fitness equipment, balcony cabinets, green plants, etc. according to your wishes, to become an exclusive “third space”. As the letter said, “Once, your balcony had nothing to do with me. Today, 13 scenes have turned the small balcony into a big world.” So are consumers living the life they want? In April, Ms. Shao, who lives in Qingdao, renewed her 22-year-old kitchen through Triwing Bird, which not only optimized the space utilization rate, but also made daily family meals more scientific and convenient. In June of this year, she lived in the South District of Qingdao. Grandpa Wang, the empty-nest elderly man, has replaced it with a smart bathroom that integrates functions such as smart voice operation, home appliance interconnection, spacious storage space, and age-appropriate safety devices through the three-winged bird. The data will not lie. From January to May this year, the sales of Triwing Bird Beijing Experience Center 001 exceeded 70 million, of which the sales of home appliances were 25.33 million, and the income of home scene + ecology was nearly 25 million. The sales of scene ecology is about to Keep up with appliance hardware. Farewell: Say goodbye to home appliance brand labels “A letter from a family letter cannot be consistent with trust; a letter from a family letter can never finish my transformation into a long one.” Times are changing, and Haier Zhijia also bid farewell to the label of “home appliance brand” in the traditional impression, and turned to a new track of scene ecological brand. So what does this shift mean for consumers, the industry, and themselves? For users, the idealized lifestyle of “smart home, new residence” is within reach. Based on the advantages of industry-leading smart web devices, Haier Smart Home uses the “Smart Home Brain” to realize independent thinking and active services in various scenarios. Smart home brain is the core technology engine of smart home. It uses technologies such as the Internet of Things, artificial intelligence, big data, and cloud computing for intelligent perception, intelligent connection, intelligent interaction, and intelligent decision-making. It continues to evolve, allowing users to feel ubiquitous and natural. The new smart home experience of communication, initiative, caring, safety, reliability, and continuous evolution is equivalent to having a smart housekeeper at home, thus realizing a smart home with a “brain”. For the industry, Haier Zhijia is using innovative models to promote the transformation and upgrading of the industry. Data shows that Haier Smart Home has fully led the formulation and revision of international standards for smart homes in international standards organizations such as IEC, ISO, IEEE, and OCF. In addition, Haier Smart Home has built the largest smart home scene ecology in the industry, accelerating the cross-border integration of the industry and creating a win-win situation. For itself, Haier Zhijia completed the subversion and continued its original intention. From the beginning to the end, Haier Zhijia’s core development logic centered on “user needs” has not changed. Faced with new demands and new trends in the new era, Haier Zhijia, which took the lead in transforming scene ecological brands, once again took the lead in the industry. Nowadays, when it comes to smart homes and scene ecology, the first response of the consumer market will be “Haier Smart Home”. The full implementation of smart homes has also driven the confidence of the capital market to rise. to sum up A “letter from home” may be difficult to describe the changes in the industry and the expectations of Haier Zhijia, but this letter once again allows the market to see Haier Zhijia’s determination to bid farewell to the past. Of course, this farewell is not the end, but the beginning of a new journey. *The pictures in this article are from the Internet

Typical 4-level U-shaped house 4-level U-shaped houses usually have the main door in the middle of the front of the house and indent while the right and left sides of the house protrude like two sides of the letter U. This design is most suitable for rural houses and houses. There is a large area of ​​land, so families with small and flat areas will not be suitable for this model. 4-level U-shaped houses with Thai roofs are popular in both the city and the countryside Normally, U-shaped houses are built in the form of 4-level houses, 1-storey houses, 2-storey houses with many different styles. The three sides of the U-shaped level 4 house are adjacent to each other and share the same front yard; This type of house architecture creates airy, easy air circulation, making the house cooler. At the same time, the U-shaped house design creates balance and squareness, so homeowners will easily divide the functional room areas; At the same time, everyone in the house can easily observe from room to room. A 4-level u-shaped house not only ensures aesthetics but also helps many households save costs thanks to a scientific way of dividing functions while still ensuring the living space of the whole family. In addition, if you want to save costs, instead of building a 4-level house with a Thai roof, homeowners can choose to build a 4-level house with corrugated iron and tile roofs; These two types of roofs give the house a traditional beauty and if skillfully combined with many details, homeowners will easily create impressive architecture level 4 houses without too much expense. . Level 4 letter L Besides U-shaped houses, level 4 houses also have L-shaped houses; These are houses built in rectangular shape, in which, the horizontal area will be shorter than the length of the house. Many people choose this design model because it both saves space and creates a space to help catch the sun and wind into the house. In addition, the gap created by the L-shaped design can also be arranged into a garden area or a parking space. Popular L-level houses Compared to the tube house design, the L-shaped house will have a much higher use efficiency. Therefore, today L-shaped houses are a favorite architectural design and built in many places, from rural areas to cities. This model overcomes most of the disadvantages when building a house on a small and narrow land area. Because it has many advantages such as turning the design of a 1-facade house into a 2-facade house, creating an airy and comfortable space for people living inside. Allows creating a garden corner that can be used as a parking space, entertainment and entertainment area for homeowners. All function rooms can open windows and balconies to receive sunlight and natural air. Design and construction time is much faster than multi-storey house designs.

On June 10th, the 22nd anniversary of iFlytek, Chairman Liu Qingfeng issued a letter to employees. He mentioned in the letter that iFLYTEK at the beginning of the year put forward the 14th Five-Year Plan of “one billion users, 100 billion revenue, and trillion ecology”, among which systemic innovation and strategic bases are the most important growth path for the next five years. , Are also the two core engines that support the rapid growth of performance.

He believes that at the current time, achieving goals requires adherence to the scientific spirit, which is to see the essence through the phenomenon, seek truth and be pragmatic, analyze and demonstrate, and be innovative and rational. First of all, we must use the spirit of science to return to the essence of value creation. “In education, whether our system can satisfy the essence of value creation depends on whether we can truly teach students in accordance with their aptitude and reduce the burden on teachers and students in the main campus. In terms of medical care, whether our system can satisfy value creation depends on whether our system can satisfy the value creation. Can it succeed in major emergencies?” Liu Qingfeng said.

Secondly, if you look at the problem dialectically with the spirit of science, there will be no short-term anxiety. Liu Qingfeng believes that continuous breakthroughs in single-point technology have become a habit of Xunfei, but the threshold of single-point technology will always be gradually overtaken by latecomers. Sticking to a single technology will inevitably flow into mediocrity and enter the red sea of ​​technology and application. “We must not only open up a position in one new technological field, continue to explore in the unmanned area of ​​technology, but also form a unique core competitiveness through systematic innovation, so as to achieve overall innovation on the strategic base and form our own Industry brand.”

Finally, he mentioned that to use the spirit of science to get out of the comfort zone, the stage is as big as the mind. “Getting out of the comfort zone is risk prevention, and it is also a development need and the desire to build the world with artificial intelligence.” Liu Qingfeng said that the status of the iFLYTEK artificial intelligence national team is constantly being strengthened, giving iFLYTEK the ability to systematically innovate and create the future. conditions of.

He also talked about the topic of “lying flat” that has caused heated discussion recently. He said that within iFLYTEK, it is necessary to use this as a vigilance to prevent young people with the ability and dreams from being flattened here, losing their internal development motivation and vigorous vitality. We must create an organizational environment that allows young people to continuously release their inner abilities, ensure that “heroes are useful”, and propose that the company resolutely opposes involution.

The following is the full text of Liu Qingfeng’s employee letter:

Today is the 22nd birthday of IFLYTEK. Thank you for your company!

The national college entrance examination has come to an end. The Guangdong college entrance examination, which has been affected by the epidemic, has been tested and no one is missing. This is the result of the joint efforts of all parties in the society, including our examination business center in Guangzhou, South China. They provided more than 50 million services for various examinations across the country last year alone; our intelligent medical assistant phone robots also rushed to help urgently in this epidemic, and quickly completed the screening for more than one million people in Shenzhen, Guangzhou, Qingyuan, etc. Check and win important fighters in the race against the virus.

The epidemic is a touchstone of human nature, a manifestation of system advantages and management capabilities, and a martial arts field for testing whether artificial intelligence is truly practical.

At the beginning of this year, we put forward the fourteenth five-year goal of “one billion users, one hundred billion revenue, and one trillion ecology”. Among them, systematic innovation and strategic bases are the most important growth paths for us in the next five years, and are also the most important support for our high-speed growth. The two core engines. Looking back at the past six months:

Good news of the education business “Teaching Students in Accordance with One’s Aptitude” project has been reported frequently. It has landed in Zhengzhou and Wuhan, and the business has grown by more than 70%. The learning machine has been well received by parents and students, and the business has grown by about 200%. In July, we will release new products; Steady growth, the completion rate of B-end software exceeded 90% year-on-year, C-end software exceeded 52% year-on-year, and C-end hardware 618 start-up sales increased by 108% year-on-year; the “Smart Medical Assistant” project of medical business moved from Anhui to the whole country, with service coverage There are more than 38,000 grassroots doctors with more than 100 million residents; the construction of “Digital JAC” in smart cities will open up our provincial base model; the digital transformation of enterprises will also open a new situation, and our “Xunfei Tuling Platform” has been given priority by the Ministry of Industry and Information Technology and Anhui Province Support and take the lead in building a digital transformation platform for SMEs.

At such a time node, how do we continue to use “systematic innovation” and “base business” to achieve our 14th Five-Year Plan?

That is to use the spirit of science to drive towards our sea of ​​stars.

What is the “scientific spirit”?

It is the rational spirit of looking at the essence through the phenomenon, seeking truth and being pragmatic, analyzing and demonstrating, and pioneering and innovative.

In today’s rapidly changing era, we particularly emphasize the need to use the spirit of science to penetrate the surface and see the essence, reduce unnecessary anxiety, and maintain long-term strategic determination.

Specifically, it includes:

Use scientific spirit to return to the essence of value creation;

With the spirit of science, you will not be short-term anxious if you look at the problem dialectically;

With the spirit of science, step out of the comfort zone, the stage will be as big as you have in mind.

1. Return to the essence of value creation with scientific spirit

At the beginning of our business 22 years ago, we put forward the core concept of “achieve employees’ ideals and create social value”. The social value we create is the core value of high added value that is sunny and healthy, representing the country’s future participation in global competition.

In education, whether our system can satisfy the essence of value creation depends on whether we can truly teach students in accordance with their aptitude in the main campus to reduce the burden on teachers and students.

On May 21, 2021, the 19th meeting of the Central Committee for Comprehensively Deepening Reform pointed out that “one of the most prominent problems of compulsory education is that primary and secondary school students’ burden is too heavy, and the short-sighted and utilitarian problems have not been fundamentally resolved. Especially for off-campus training institutions. Disorderly development.” After that, those education and training institutions that relied on capital power to expand disorderly, over-marketed the anxiety of parents, and relied on duck-filling training to invade their children’s childhood, were repeatedly punished and laid off frequently; and iFLYTEK was in the process. On the contrary, China’s share price hit a new high.

Because our “Teaching students in accordance with their aptitude” is to strengthen the value of the main position of school education, assist teachers and students to return to school, do a good job in teaching within a limited time, free up children’s time, and let children change from duck-filling training to autonomous learning with the help of intelligent learning machines . It can be found that more and more children have improved their academic performance and reduced their learning time through our “teaching in accordance with their aptitude”: Taking a single knowledge point as an example, the amount of exercises for children has been reduced by 32%, and the learning time has been reduced by 48%. Let children have time to play, explore and cultivate their curiosity and thirst for knowledge.

Education is the foundation of a country. If education is not good, children are not good, and the future of the country cannot be good. The country’s long-term investment strategy of fiscal education expenditures accounting for 4% of GDP remains unchanged. As long as we meet the essence of value creation, the stars and seas of artificial intelligence empowering education will come naturally. .

In medical care, whether our system can satisfy value creation depends on whether it can survive major emergencies.

During the rebound of the epidemic in Hefei, the Hefei Municipal Party Committee and Government held a special meeting to clarify the need to speed up the deployment of our epidemic prevention and control system; in this Guangzhou epidemic rebound, our intelligent epidemic prevention and control multi-point trigger system was activated as soon as possible. Nansha District As soon as we announced the strengthening of management and control, we immediately surveyed the 5464 “key populations for investigation” in Nansha. It took only one hour to call, and immediately screened 853 people who had been to the medium- and high-risk areas of the epidemic in the past 15 days, and 110 people did not. He has done nucleic acid and generated statistical reports through these dimensions to help the government make accurate decisions.

2. Using the scientific spirit to dialectically look at the problem will not be short-term anxiety

Some external voices say that the threshold of voice technology is constantly lowering, and some of our friends are a little anxious. In fact, from speech synthesis to speech recognition, from machine translation to natural language understanding, single-point technology continues to break through. This has become our habit at iFLYTEK; however, the single-point technology threshold will always be gradually overtaken by latecomers. Sticking to a single technology will inevitably flow into mediocrity and enter the red sea of ​​technology and application .

We will not only open up positions in one new technological field after another, and continue to explore in the technological no man’s land, It is also necessary to form a unique core competitiveness through systematic innovation , In order to achieve overall innovation on the strategic base, and form our own industry brand.

Many parents are now anxious about their children’s performance even in elementary school or even pre-school education. In addition to grades, education must be able to cultivate children’s learning interest and curiosity, develop good learning habits and physical fitness. Through our “teach students in accordance with their aptitude”, we can make children have a firmer grasp of knowledge points, and free up time to exercise creative thinking to achieve the five education simultaneously; we can also help parents understand which subjects are most in line with their children’s talents. These are all It is a core contribution beyond the acceptance rate, helping the country’s selection system and achievement orientation to diversify. As long as we persist in using rational thinking to help parents reduce their burdens, we can become a stream of value creation in the era of general anxiety education.

3. Get out of the comfort zone with the spirit of science, and the stage will be as big as you have in mind

Most people are used to staying in the comfort zone. However, the development of Xunfei is the process of stepping out of the “comfort zone” and exploring unknown boundaries:

Technically, it is from synthesis to recognition, to semantic understanding; from Chinese to English, to multilingual; from speech to image; from perception to cognition; from being able to listen and speak to being able to understand and think. With the breakthrough, we can undertake the construction of the only State Key Laboratory of Cognitive Intelligence, become one of the first four open artificial intelligence platforms in the country, and become the “national team” in the field of artificial intelligence.

In business, if you are satisfied from language learning to intelligent evaluation, there will be no current “teach students in accordance with their aptitude” so that every child can enjoy a high-quality and balanced education; if they are satisfied from electronic medical records to intelligent medical assistants, there will be no current intelligent epidemic The prevention and control system provides artificial intelligence power for orderly epidemic prevention and control; if you are only satisfied with occupying more than 60% of the market share in the car voice kit market, you will not have the courage to force yourself to reach in-depth cooperation with many car companies. And self-breakthrough to enter the field of autonomous driving.

We want to move on to a bigger stage, just to do things that can only be gained by jumping up and forcing ourselves to continue to make breakthroughs. Getting out of the comfort zone is not only risk prevention, but also development needs and the desire to build the world with artificial intelligence.

The status of our artificial intelligence national team is constantly being strengthened, giving us the ability to systematically innovate and create conditions for the future.

In 2017, the “New Generation of Artificial Intelligence Development Plan” mentioned that speech recognition is the world leader, and the country’s first batch of intelligent speech artificial intelligence open innovation platforms settled in Xunfei. Four years later, on May 28th, General Secretary Xi Jinping once again proposed at the academician conference of the two academies, “China’s speech recognition is at the forefront of the world.” This makes us very proud. We have done it in the country’s mission; The secretary pointed out that we have entered the era of intelligent interconnection of all things with the ternary integration of “human, machine and things”. In 2019, we proposed that “intelligent voice interaction will become the most important entrance for human-computer interaction in the era of interconnection of all things”. HKUST Xunfei took the lead in establishing a new standard system in the field of intelligent voice and accelerated the construction of the national technology standard innovation base; on May 27, under the witness of eight leaders from Shanghai, Jiangsu Province, Zhejiang Province and Anhui Province, HKUST Xunfei took the lead The chairman of the Yangtze River Delta Artificial Intelligence Industry Chain Alliance was formally established; at a special meeting organized by the Anhui Provincial Government on June 3, Governor Wang Qingxian made it clear: We must give full play to the leading advantages of intelligent voice technology represented by iFLYTEK, and accelerate the development A complete artificial intelligence industry system featuring intelligent voice.

The best way to foresee the future is to create the future.

If we want to achieve the development goals of the 14th Five-Year Plan and our cause is to benefit more mankind, we must let talents from all over the world join our ranks and give them a bigger stage. Recently, the topic of “lying flat” has aroused heated discussion. Many people laugh at themselves and say that I don’t want to work hard, but on the other hand, the number and popularity of online knowledge videos continue to increase, indicating that young people now have a strong self-drive and spirit of striving and enterprising, and they are a generation with dreams and personality.

In fact, many young people are very good, but some may not have a platform for growth and display, so that the ceiling of the workplace will soon come. Inside iFLYTEK, we must also take this as a vigilance to prevent young people with the ability and dreams from being flattened, losing their internal development momentum and vigorous vitality here. We need to create an organizational environment that allows young people to continuously release their inner abilities and ensure that “heroes are useful.”

Within the enterprise, we firmly oppose involution, Anything that can’t really create value for customers is an involution that is not worth the effort: Those that require a uniform format on insignificant matters are internal scrolling; those that spend time and energy on handling internal interpersonal relationships are internal scrolling; those that consume the lives of employees for multiple rounds of reporting. Our eyes should look outward, and the external tension that forms the organization is the fundamental way to solve the involution.

We hope that cadres at all levels of iFLYTEK can truly understand young people and look at problems from the perspective of young people. We need to first solve the young people’s survival pressure and growth pressure. From the perspective of “why not eat meat”, it is unobjective and unfair to put higher demands on young people who first need to solve the problem of food and clothing.

Struggle is the background color of youth, but it requires “civilian and martial arts, one relaxation.” We will continue to release the vitality of the organization, so that young people have greater motivation for growth, and every step of the happy struggle will have tangible rewards.

Today, population aging and declining birth rate are the general trend. Building a happy China must rely on artificial intelligence; the demographic dividend is gradually disappearing, more and more jobs will not be undertaken by young people, and building an industrial power must rely on artificial intelligence.

Artificial intelligence is taking on the important task of reshaping the competitive landscape of the global industrial chain. Standing at the new starting point of the 14th Five-Year Plan, facing the big future of artificial intelligence, we are in a golden window period and stand on an unprecedented stage.

No one can stay old, but the struggler is always young.

May we have hills in our breasts and mountains in our eyes.

Together, create the future!

Recently, however, a coalition of 44 US attorneys general signed a letter to Facebook CEO Mark Zuckerberg, listing reasons and citing research suggesting Facebook should not continue with the plan. develop the Instagram app for kids. One of the reasons listed in the letter is: Facebook has had many controversies in the past related to protecting children’s privacy; other research also shows that social media can harm children both physically and mentally; children do not have a complete understanding of privacy and can easily become targets of anonymous criminals; especially the large percentage of young Instagram users surveyed have experienced cyberbullying on this app. It seems that with the development of Instagram for Kids, Facebook not only failed to meet the need, but even created another need, as the platform mainly appeals to children with or without Instagram accounts. In short, an Instagram platform for young children will be harmful for a multitude of reasons. The attorney general urged Facebook to drop its plans to launch this new platform. In a statement released by Attorney General Maura Healey, the head of the coalition, she cited Zuckerberg’s rejection of the idea that social media is harmful to children. The statement points out that there is much evidence and research that contradicts Zuckerberg’s denial. Currently, children under the age of 13 are not allowed to own an Instagram account unless the description of the profile clearly states that the account is being managed by a parent or guardian. Back in March, Instagram released a blog post showing their efforts to protect minors under the age of 18 on the platform. The AG Alliance believes that this is not enough, especially for those under 13 years old. According to Gsmarena

However, have you ever wondered where this huge treasure of knowledge, from drawings, historical books or records of artistic quintessence, is kept? The answer is papyrus. Traces of majestic history, primitive knowledge from one of the first human civilizations recorded on papyrus, passed from generation to generation. Therefore, the papyrus has become a symbol of culture, spirituality and history of ancient Egyptian society, as well as the precious heritage of modern Egypt. Paper roll of papyrus. (Source: UK McClung Museum) Ancient, versatile The papyrus papyrus is one of the oldest known plant species known to mankind and Egypt is considered the origin of this plant. The papyrus grows in the swamps on both sides of the Nile River, relying on the sediments of the Nile to nurture and grow. The oldest recorded record of the appearance of the papyrus tree is that of the Greek historian Herodotus, in 450 BC: “The papyrus grew from the swamps, the body was fine. cut and processed into different products, the lower rhizome is eaten or sold ”. The ancient Egyptians discovered the value of papyrus in everyday life. Not only was the main material in papyrus paper production, papyrus also had many other uses in the daily life of ancient Egyptians. The lower stems and roots can be eaten raw or grilled. One can chew on the papyrus stalk, swallow the water and then spit the pulp like gum. Papyrus is also braided as a rope, fishing net, even a boat or decorative details on a boat. In households, papyrus can be used as firewood for cooking, knitting into everyday items such as bags, corks, bed sheets, carpets, curtains, slippers … In the medical field, dry papyrus ash is used to treat skin diseases (caustic, calluses …) or prevent cold sores from developing. The Papyrus habitat is wetlands along the banks of the Nile. (Source: African Plants – A Photo Guide) Witness of history In ancient Egyptian cosmology, the world was created when the first god stood on a mound emerging from the infinite darkness, indistinguishable between darkness and water. Every year, this mound will emerge from the water with the papyrus. Therefore, the papyrus is the symbol of fertility, rebirth, the germ of creation. In that sacred sense, the ancient Egyptians used papyrus as amulets, funerals, mummies or paintings in temples. Amulets made from the papyrus tree are worn around the neck, sewn on a mummy’s scarf, or placed under the mummy’s head to help the deceased feel as warm as they were alive despite having stepped foot into the afterlife. The paintings on the walls of many tombs show that papyrus was used in ceremonies or funerals. The attendees at the ceremony often carry papyrus stalks as an offering to the gods. There is an opinion that when thinking of Egypt, people immediately think of papyrus. The ancient Egyptians invented papyrus paper for so long, so long that it is impossible to determine the exact time. Much of the history of Egypt and the ancient world came to the modern world through information written on papyrus. The use of papyrus paper from the I Dynasty, 3100 BC is recorded on frescoes in the shape of a scroll, and is also considered an image of a book. So how was papyrus produced by the ancient Egyptians? First, they pulled the papyrus stalk out of the swamp, tied it in bundles and brought it to the processing plant. Then, the stalk is cut into thin slices, soaked in water for several days to soften. Finally, the slices are layered, squeezed out of water and strengthened adhesion. The papyrus is dried, which can be glued to increase length depending on the intended use.

During the 1903-1920 excavation at the village of Deir al Medina (the residence of those working for tombs in the Valley of the Kings), in the city of Thebes (now Luxor) by the Italian Egyptologist. Leading Ernesto Schiaparelli, historians found 16 meters of papyrus, known as the “Book of the Dead” on the tomb of the main craftsman Kha and his wife Merit (built around 1386-1349 BC ). This is an ancient Egyptian religious document, another name is “The Book of Light” or “The Letter”, a collection of spells and spells recorded to help the soul of the dead to the next world. the other through “Underworld Gate”. The book was written by many priests over a period of 1,000 years. Originally, this book was inscribed in hieroglyphs in pyramid mausoleums and served only to the Pharaohs. However, by the New Kingdom period (1550-1352 BC), this book was copied on papyrus by priests and used for princes, officials, and the upper class. The letter will be read during the mummification process and left in the tomb of the dead. Kha and his wife Merit in front of Death Osiris sitting under a papyrus tree in the Underworld. (Source: UK McClung Museum). Wait for the day “reborn” Today, under the influence of topography, environment and the development of modern settlements on the banks of the Nile, the papyrus tree is almost extinct in Egypt, and as a result, papyrus paper making has gradually faded. one. A small village in Egypt, one of the last to retain the papyrus tradition, is called Al Qaramous (Al Sharqia province). Artist Atef Mohamed Shehata is one of the few artisans in the village who also harvests papyrus and produces papyrus paper. Papyrus seeds are planted and it will take about a year to reach harvestable maturity. After harvest, the tree will regrow in about 1-2 months. Once upon a time, the whole village was covered with papyrus tree, but up to now, the area of ​​this tree is only about 4 hectares. At the end of the finishing process, the papyrus will be sold to other artists in the village, one of which is painter Saied Tarakhan. Finally, paintings on Papyrus paper will be sold at souvenir shops. However, the Covid-19 epidemic broke out, causing a significant decrease in the number of tourists, directly affecting the livelihoods of the villagers, who mostly depend on the harvest and sale of papyrus paintings. Tarakhan artist had to leave all of the studio’s painting staff and partially shut down the workshop. However, with the craftsmen Shehata and Tarakhan, papyrus has become a sacred part of life. They will continue to preserve the tradition of papyrus and papyrus painting for many generations to come, with the same hope that this tradition will continue to be restored, more brilliant and true to the meaning of the “rebirth” of the papyrus species. .

At 9 a.m. on April 23, Times Finance called the Office of the Secretary of the Board of Hope Co., Ltd. The other party stated that the reply has been submitted to the Shenzhen Stock Exchange, and the specific content is not convenient for disclosure at present. However, as of press time, the content of Houpu’s response has not yet appeared on the Shenzhen Stock Exchange website.

On April 21, the Shenzhen Stock Exchange issued a letter of concern and an annual report inquiry letter to Hopu within one day. The serial follow-up questioning by the Shenzhen Stock Exchange revealed its eagerness, requiring Houpu shares to respond to the letter of concern before April 22.

The Shenzhen Stock Exchange’s attention to Houpu shares stems from the 15 billion yuan project agreement disclosed by Houpu shares on April 20.

On the evening of April 20, Houpu shares announced that the company and Chengdu Xindu District Government signed the “Hopu International Hydrogen Energy Industry Cluster Project Investment Agreement” (hereinafter referred to as the “Agreement”), and plans to invest 15 billion yuan in construction Hopu International Hydrogen Energy Industry Cluster Project.

It seems to be a major positive news for the company, but when it is placed on Houpu shares, it makes people suspicious. Its annual report shows that in 2020, its operating income will be only 478 million yuan and a loss of 168 million yuan.

Where did the poor performance of Houpu shares to complete the 15 billion yuan project?

In the letter of concern sent by the Shenzhen Stock Exchange to Houpu, it not only questioned the feasibility of the 15 billion project, but also asked whether it involved real estate development and operation. In the annual report inquiry letter issued on the same day, the Shenzhen Stock Exchange further inquired about Hopu’s operating conditions and asked for an answer within a week.

Affected by this, Houpe shares closed down 5.59% on April 22; it fell below 3% at the opening on April 23, but then quickly rose. As of the morning’s close, Houpe shares rose 5.74%.

Where does 15 billion come from?

The financial situation of Houpu shares in recent years is not optimistic. The two letters issued by the Shenzhen Stock Exchange on April 20 focused on one question: Where does the 15 billion come from?

According to the financial report, Houpu’s revenue in 2019 is 543 million yuan, which is nearly cut in 2015 compared with the revenue at the beginning of listing, and the net profit in 2019 is only 20,827,600. In 2020, the performance of Houpu shares further declined. The total annual operating income was 478 million yuan, a year-on-year decrease of 11.87%, and the net profit attributable to the parent was 168 million yuan, a year-on-year decrease of 905.35%.

According to the “Agreement”, the first phase of the Hydrogen Energy Equipment Industrial Park project uses about 300 acres of land. The Xindu District Government will only use about 300 acres of land for the first phase of the project’s fixed assets (excluding land) investment amount to 4 million yuan per acre or more. Land supply for the second phase of the project will be initiated; similarly, the first phase of the Hopu International Hydrogen Energy CBD project covers an area of ​​about 118 mu, and the investment in fixed assets (excluding land) reaches 7.5 million yuan/mu or more before the second phase of land supply will be initiated.

Based on this data, Times Finance estimates that the first phase of the hydrogen energy equipment industrial park project needs to invest at least 2.085 billion yuan.

However, as of the end of 2020, Houpu’s total assets were 1.912 billion yuan, and the balance of monetary funds was only 136 million yuan; during the same period, its current liabilities were 750 million yuan, including 116 million short-term loans.

The Xindu District Government stated in the “Agreement” that it supports and encourages district-owned platform companies to participate in the clean energy industry fund initiated by Houpu. The first phase of the industrial fund scale is 500 million yuan, of which the district-owned platform company invests 200 million yuan. Two batches of investment; in addition, the district government also encourages and supports district state-owned enterprises to participate in equity investment in the project under this agreement, and the total investment amount does not exceed 200 million yuan.

In addition, the “Agreement” requires Hopu Co., Ltd. to register relevant project companies with independent legal personality in Xindu District, and at least one project company has a registered capital of 500 million yuan. On April 16, Yanxin Holding Group Co., Ltd. (referred to as “Yanxin Holdings” in the text) and Houpu’s subsidiary-Beijing Houpu Hydrogen Technology Co., Ltd. registered in Xindu District to establish Chengdu Houpu Hydrogen Technology Co., Ltd. , Registered capital of 500 million yuan, of which Beijing Hopu Hydrogen Energy subscribed 400 million yuan, and Yanxin Holdings subscribed 100 million yuan.

Even without considering the liabilities, according to Times Finance’s estimates, plus the 170 million yuan that Houpu shares planned to raise from Wang Jiwen in February 2021, and the 100 million yuan that Yanxin Group invested in the establishment of Chengdu Houpu Hydrogen Energy, Houpu has made every effort to spend about 1.106 billion yuan in international hydrogen energy industry cluster projects, and there is still a big gap between the 2.085 billion yuan required for the first phase.

Hope shares may choose to seek external financing. Times Finance found that in the signing of the 15 billion project issued on the official website of Hopu Co., Ltd. on April 21, the world industrial gas giant-French Air Liquide (Air Liquide) Chairman of the Board of Directors in Greater China, Lu Yuebing, also attended the signing ceremony. . In 2019, Air Liquide Group and Houpu Co., Ltd. jointly established Air Liquide Houpe Hydrogen Energy Equipment Co., Ltd. (hereinafter referred to as “Air Liquide Houpe”).

On April 22, Times Finance called Jin Jing, the media liaison of Air Liquide Group, who stated that the cooperation between Air Liquide Group and Houpe is limited to the previously established joint venture company-Liquid Air Houpe. Recently, Houpe shares and Xindu District Government The project has nothing to do with Air Liquide.

Times Finance also contacted Chengdu Xindu District Investment Promotion Bureau and Xindu District Modern Transportation Industry Functional Zone Management Committee on the same day, trying to inquire about the details of Hopu International’s hydrogen energy industry cluster project. The staff of the other party said that they would record the problem and give feedback to the relevant person in charge, but as of the time of publication, no response has been received.

At the 2020 online performance briefing meeting of Houpe shares held on the same day, Times Finance asked Huang Yaohui, general manager of Houpu shares, on issues such as “whether it will introduce other investors to join the projects in Xindu District”. The other party said that the specific situation will await the company’s response to the “Letter of Concern”.

Cement boss enters hydrogen energy

At the end of 2020, Houpu shares only changed the actual controller. Another identity of Wang Jiwen, the current actual controller of Houpu shares, is the chairman of Yanxin Holdings.

According to its official website, Yanxin Holdings is a diversified group company integrating building materials, environmental protection, metallurgy, finance, investment, logistics, real estate, and equipment manufacturing, with total assets of more than 4 billion yuan. Its building materials sector can produce 4 million tons of cement and 2.25 million tons of clinker each year. Its leading products include “Diamond” and “Jun” cement.

Cement boss Wang Jiwen entered Houpu shares back three years ago.

In November 2018, in order to alleviate the pledge of shares held, Jiang Tao, then chairman, general manager and actual controller of Houpu Co., Ltd., planned to raise funds from Beijing Xingkai Investment Co., Ltd. (hereinafter referred to as “Beijing Xingkai”). According to Tianyan Check, Wang Jiwen and Yanxin Holdings own 99.02% of Beijing Xingkai.

At the beginning of 2019, the senior management of Hopu Co., Ltd. carried out intensive mobilization. First, in January 2019, Jiang Tao resigned as general manager and was replaced by Huang Yaohui, the former vice president of Yanxin Holdings; then in March 2019, Wang Jiwen succeeded Jiang Tao and was elected chairman of Houpu Co., Ltd.; on April 1, 2019, Houpu The shares completed the change of legal representative and changed from Jiang Tao to Wang Jiwen.

However, it was not until the end of 2020 that Wang Jiwen truly became the “master” of Houpu. On November 17, 2020, Houpu shares announced that Jiang Tao would transfer 20% of his shares to Wang Jiwen and Beijing Xingkai. After the completion of the transaction, Wang Jiwen and Beijing Xingkai controlled by Wang hold 25.51% of Hopu’s shares and are the actual controllers of the company.

Soon after Wang Jiwen took office as chairman, he changed the company name from “Chengdu Huaqi Houpu Electromechanical Equipment Co., Ltd.” to “Houpu Clean Energy Co., Ltd.”.

A relevant person of Houpu said in public that the new boss Wang Jiwen is optimistic about the development of hydrogen energy.

The name change may have demonstrated Wang Jiwen’s confidence in hydrogen energy and other clean energy businesses, but it failed to help Houpu shares to reverse the decline in performance.

Transition to hydrogen energy for 7 years, revenue accounted for less than 1%

In recent years, the hydrogen energy industry has become hotter and hotter.

Kaiyuan Securities believes that in the context of “carbon peak” and “carbon neutrality”, hydrogen is expected to play an important role in promoting energy transition and improving the flexibility of the energy system. The governments of Sichuan, Beijing, Jiaxing, Zhejiang and many other places have also launched their own “14th Five-Year Plan” for the hydrogen energy industry.

On April 21, the China Hydrogen Energy Alliance revealed at the “14th Five-Year” Hydrogen Energy Industry Development Forum that as of the end of 2020, China has built 128 hydrogen refueling stations and the cumulative number of hydrogen fuel cell vehicles has reached more than 7,000.

The “China Hydrogen Energy and Fuel Cell Industry White Paper 2020” released on the same day shows that China’s current hydrogen production capacity is about 41 million tons per year, and the output is about 33.42 million tons, making it the world’s number one hydrogen producer; by 2060, under the carbon neutral scenario, it can be The scale of hydrogen production from renewable energy is expected to reach 100 million tons.

Wanlian Securities analyst Jiang Wei told Times Finance on April 22 that in the future, with the reduction of fuel cell costs, the layout of hydrogen refueling stations, and the promotion of photovoltaic hydrogen production, hydrogen energy is expected to become the preferred alternative energy source in the non-electric field. Can be used on a large scale.

In order to catch up with this round of hydrogen energy boom, Houpu has been preparing for 7 years.

The prospectus submitted by Houpu in 2014 did not mention that the company has any hydrogen energy projects. However, in its 2015 annual report, there was a message that “the hydrogen charging device has achieved phased results, and the research and development prototype has been tested on site”. Every year since then, Houpe has announced its progress in the field of hydrogen production and hydrogenation.

But so far, hydrogen energy has not yet become Hopu’s main business. In its announcement on April 8th, Houpu shares mentioned that in 2020, the company’s main operating income will still be the natural gas refueling equipment and parts business, and the company’s hydrogen energy business recognized operating income in 2020 is less than total revenue. 1%.

Perhaps in order to break through this 1%, Houpu shares will spend a lot of money to invest in the hydrogen energy industrial park. But with 1.106 billion funds to leverage 15 billion projects? difficult.

Illustration: Dinh Huong Hue told Lich: “When I have a little capital, I will open a company, I will not work as hired labor, so I will see you every day.” Love is like that, people who always need to meet people every day like waking up every morning to see the sun throw brilliant golden rays of sunlight on the ground. But Hue’s work often takes long trips. When she arrived at home without Lich, Hue stuck multicolored sheets of paper on the door of his house. These words are like replacing Hue rabbits with Lich: “God, I have to go to work again today. So I can’t have lunch with you this Saturday. Kiss you”. “You’re spoiled. The other day I told you to go wherever you go, bring a raincoat to keep in the trunk of the car, but you don’t obey. Rain, when you are sick, whoever goes out to go to the market with me. I bought you a raincoat, I kept it in a place where … only the two of us know “. “In a place where only the two of us know” was an empty slot of the house’s two walls, covered with an old, green moss-colored concrete block. “Brother, I miss you so much today.” Sometimes the words on the paper are just that. But is it not necessary to write long enough to spread all your thoughts with your loved one? Sometimes just one word implies a heart leaning toward one heart. Or sometimes, on the other piece of paper just a mere word: “Angry”. The word angry is sometimes very pitiful because he has to endure the monsoons blowing on the street, when Lich has not read, the paper on the door has to turn up and down like hangover be removed, put into the anniversary box. *** Love each other for a month and 12 days, then they get married. All love after walking through the streets of the city, visiting all the sidewalk eateries, even sitting tired in cafes large and small – often end with two people together. about living in the same roof. Calendar laughed with Hue: “Let’s save some money together”. Hue laughed: “That means someone cleaning the house, cleaning the house, rubbing the cigarette butts you smoke, washing the clothes for you to wear, putting the curtains for you to sleep … right?” Calendar shakes his head: “I don’t mean that. I mean when I invite you to breakfast, I have you by my side. No need to call to ask if I have free time? ” Hue pouted: “Get married to have someone go to breakfast and coffee, but do you love me?”. Without answering his wife’s words, Lich just whispered: “Probably no one has stuck the red and green papers in front of my door from now on” … Then Hue opened a real company. Many things learned from the old company, when being assigned to the position of assistant director, helped Hue to have many business partners. Hue is an experienced person in communication, capturing the thoughts of guests. On the day of the company’s opening ceremony Hue, flowers congratulate a lot. In the afternoon of his wife, Lich also sent his wife a huge flower basket with 100 roses. Calendar said: “I should only send 99 roses as in some piece of music. But now you and I are husband and wife, so you have to even count ”. Hue put on her lips with a gloss of lip gloss, sprinkled some pretty glitter, kissed her husband’s cheek: “Thank you. Thank you, General Manager ”. The calendar looked in the mirror, saw that his wife’s lipstick was on her cheeks, and was also happy: “Come on, make me the general manager so that tomorrow I will make you surrender, right?” Hue laughed loudly: “That’s right”. *** The multicolored sheets of paper with a corner of a flower no longer appeared on the door, now hastily written words on the letter pad left at the table in the living room. Hue’s work increasingly attracted Hue away from her role as a wife. In the past, when two people fell in love, Lich once said: “I really crave family meals. Just sitting with you to eat, even if you just eat water spinach dipped in fish sauce, I will feel delicious ”. Hue laughed very happily: “What can I do to let me eat water spinach dipped in fish sauce? I will let you eat stir-fried morning glory with garlic and chili sauce “. The days when two people meet each other are rare, meals together are rarer. Every time I go home in the afternoon, Lich often sees the words Hue written. “Bro, I have stocked meat, I also keep raw vegetables in the fridge. You can just eat rice by yourself. Today I have to receive guests. Have a good meal.” “Today is Grandpa’s death, isn’t it. I kept the money in the envelope. You brought it over to your house, saying I’m sorry for so much work.” “I have to go on an unexpected business trip for a few days. Don’t be sad, honey “. Sometimes, if he wanted to say something to his wife, Lich also had to write quickly on a piece of paper: “Are you not afraid that you forgot me, your wife? You stay at home alone, eating alone like a man. he is single, boring “. “What, I call you for an hour. You keep writing on the desk like in the old days?”. “Next week, my agency organized to go to Da Lat. Try to arrange it. It has been a long time since we went out together.” Then very when angry, he wrote in large letters: “I LOOK SO MUCH. I LIKES YOU”. Hue answered her husband with the words: “I also miss you very much. Lately I’m a little busy, I sympathize with you”. Just like that, the handwritten papers of Hue and Lich have become thicker than ever without Hue’s knowledge. Until one afternoon, after a week of market research. Hue came home. Hue plans to spend a week with Lich, the couple will have an outing such as Ha Long Bay. Hue figured how happy Lich would be. He would embrace Hue and shout: “Yes, it has been a long time since I went out”. But the door to the house is closed even after work is over. Hue was surprised and did not understand that Lich was going to hang out at the inn with friends? Because Calendar almost does not have that habit. Suddenly Hue was startled when she entered the house. On the wall of the living room are pictures of Hue written for Lich. There are many colored sheets of paper from the time the two fell in love and also sheets of paper when the two were married. The calendar writes a large line of letters with a black brush: “I’m so sad. I’m going to drink.” The sheets were removed by Hue and put back in the box. Hue quickly dressed, drove the car into the dark. Hue went to find Calendar. Hue did not want everything to become too late, if she let Lich not return with her today. In the house with husband and wife. Short story by Phan Thi Tan

Mr. Le Tien Chau – Secretary of the Hau Giang Provincial Party Committee. Photo: CK On April 23, in the letter to the cadres, party members, civil servants, officials and workers in Hau Giang province on the 46th anniversary of the Liberation of the South (April 30, 1975 – April 30). / 2021) and celebrating the 135th anniversary of the International Labor Day May 1, Mr. Le Tien Chau – Secretary of the Hau Giang Provincial Party Committee said: In the context of the province still faces many difficulties and challenges: the situation climate change, landslides, droughts, saltwater intrusion, diseases have many complicated developments; socio-economic infrastructure, limited investment resources; Human resources are still weak, lack of high-quality labor.

Using computational tools, researchers can virtually open a complicated folded letter from 1697. These are complex techniques to help recipients detect if a message has been tampered with. To date, scientists say letters over 300 years old can be read without opening. Read letters using algorithm During research at the Vatican Secret Archives, conservator Janaa Dambrogio at the MIT Library (Massachusetts Institute of Technology in America) unearthed Renaissance letters with strange cuts and angles. . She found these were signs that they were initially locked with a sliding paper slot and sealed with wax. Such letters cannot be opened without tearing the letter – which helps the recipient to see if the letter has been read or not. After studying 250,000 ancient letters, Dambrogio and her colleagues invented the first system for classifying key-lettering techniques. This is a type of periodic table based on how to crease pages. “Mail lock is 10 thousand years old technology and since people try to secure their mail, gradually they have come to know the key features of mail lock” – Ms. Dambrogio said. Until now, scientists have only read these letters by cutting them out and often corrupting the letters. Although such work naturally focuses on the content of the letter, it is also important to research the letter lock. Dambrogio and her colleagues have devised a way to both read the locked letter’s text without opening it, while at the same time reconstructing the intricate folds and gaps used to fix it. “This is an interesting and pretty big contribution over the decades to the search for artifacts that have barely been opened yet,” said computer scientist Brent Seales at the University of Kentucky. He is not involved in this study. The scientists investigated the Brienne Collection – a postmaster’s chest containing more than 3,000 unsent letters, of which 577 were never opened. Letters sent from all over Europe to the Dutch city of The Hague between 1680 and 1706, the era when Salem witch trials unfold, Newton revealed his law of motion and gravity. King Louis XIV moved the court to Versailles. First, the researchers analyzed four envelopes by scanning high-resolution X-rays to create 3D models of the letter. They then use a new algorithm to identify and separate different layers of folded letters and recognize the written text. In the end, the algorithm virtually unfolds the letters, not only making the handwriting visible, but also records the crease patterns so that the researchers can re-create the step-by-step letter locking process. Scientists use technology to read locked letters dating back centuries. Open up many research directions Scientists have found a way to read the letter without breaking its seal or opening it in any way. Using highly sensitive X-ray scanners and computer algorithms, researchers can read these sealed letters. The new strategy above helps scientists read the text in unopened messages for the first time. For example, an unopened letter is from a man named Jacques Sennacques, dated 31/7/1679 to his cousin Pierre Le Pers – a French businessman in The Hague. Perhaps this letter was intended to obtain a certified copy of the death certificate of a relative, Dainel Le Pers, regarding the inheritance issue. The scientists detailed their findings in the recent Nature Communications journal. This new technique will also work for other collections of unsent mail around the world. For example, “there are so many old origami art pieces that the way they were created has never been recorded,” said study co-author Erik Demaine, a computer scientist at MIT – “The idea of ​​scanning them so they can replicate the way they are folded is really interesting.” The historian Howard Hotson at the University of St Anne in Oxford, UK was not involved in the study, however he stressed that future research on locked letters could shed light on cultural patterns and patterns. global technology exchange “because sophisticated mail locking techniques have been transferred from one country, sector or continent to the respective places over the long period in which it is used”. Scientists are making their technology and open source available for others to use and possibly improve. “We see this as the starting point for many future research directions,” said co-author of the study, algorithm engineer Amanda Ghasaei at Adobe Research in San Francisco.

Early autumn. There the fog became clear in the hills. Forty years then the dew goes on falling and remains transparent. Mist was light in her hair, her slightly curly, cloudy hair is now close to the color of the mist. Mist blended in a magical, pure white smoke soared up. Shakily, she lifted her thick, neatly tied booklet, which had been stained with gold in the past. She has carefully kept them and the letters he has written to her for forty years! The soft, italic letters she had written to him with the ink colors of that day far away. They were shivering and beautiful like a woman far away from her husband in passionate love. She has kept them as her treasures since his death. The letters with her have seen so many autumn seasons pass even without him – a talented and destined husband soon passed away at the age of four-five. The fall is special with blue hair. The fall is special with white hair. The autumn leaves yellow leaves … Forty autumn had passed, etched on her face many traces of ups and downs, suffering, loneliness, and fear. That vitality, that soul, and that happiness still shone in her eyes. Countless tears of happiness and bitterness each earned. Forty seasons passed, she never forgot the man of her life. No one can replace him. Even now, his face, his voice, his smile, his figure and his soul filled her mind. Yes, in that place the mist had become transparent. She saw the white mist drifting softly, a fantastical, far away color. The remote mountainous area is covered with mountains and hills and thousands of white clouds gradually appear in the sacred smoke … There he and she met in the days of resistance and hardship. A simple and crowded wedding of a nurse in her hometown ripe red during the famous lychee seasons with a young teacher from Nam Dinh study land volunteered to start a career in the highlands. They – a pair of talented boys and girls. There she had four gentle, fragile daughters like four angels. There, she became a doctor in the highlands with a lot of work and dreams of saving people far away from the border! That place is high mountain. Mountainous region with simple people like mountains, sincere like hills and free soul like cool streams flowing, flowing forever … Flowing away. Flowing away. The Red River is rolling dark red alluvium that has dared sweat, tears and blood for generations. She thought dreamily about that beautiful and poor country, where people are always open, honest and open, they are so romantic like clouds, their souls are as green as a mountain, clear like a spring … The letters are being transformed into flames. The flames are doing their part. Fire broke out and the spirit rang with the sound of leaves. Strong aroma of smoke and alcohol. (Before burning the letters, she splashed on them a few drops of fragrant wine, the famous mountain corn wine he liked in the past …) She sent him the whole autumn through each green leaf dome and the whispering song of the wind. She sent him the blue sky and the richness of the trees floating with white clouds. Yes, only you know, you only understand. Only he felt deeply and saw through her sadness as clear as the dewdrops of her morning dew. Only he knows how beautiful she is. How charming and lonely, how small? Because of that, she understood very well why she became stronger, stronger, weaker and more lonely than many other women. Wherever she went, she could see his footprints with him. In whatever joy with her children and grandchildren, she realized that his smile sparkled, They were imprinted on the autumn paths of her life. The letters have flown to the sky and you will get it all. She smiled contentedly and found herself no longer alone. I feel more beautiful, gentler, and softer as many women in this world. Standing still in front of his grave, gazing at the silent motion picture on the tombstone, she gazed up at the windy sky overflowing white clouds. In the widow’s heart, there was a whisper: “Please send back love in the golden autumn seasons” … And here, right now the transparent autumn droplets are falling sparklingly!

In 2008, the movie Changeling by Clint Eastwood recalls one of the most bizarre and tragic stories of the 1920s. Single mother Christine Collins says her 9-year-old son, Walter Collins, went missing in March 1928 at home. exclusively in Los Angeles City – USA.

Five months later, the police brought “Walter” back to Mrs. Christine but it was not Walter but another boy. Although the woman knew this was not her son, the Los Angeles City police dispelled Christine’s concerns, even accused her of failing to fulfill the mother’s responsibility and forced her to go to a mental hospital.

Walter Collins is never actually found. Some time later, authorities believed the boy was one of the victims of the convicted child murderer Gordon Stewart Northcott. Meanwhile, Northcott’s mother confessed to the murder of Walter.

So far, the boy’s body has not been found and no one knows what happened. It is also unclear why the police wanted to cover up the boy’s disappearance that they brought another child to Christine and tried to convince the woman and the public that it was Walter. .

11. Female students go to another planet?

Paula Jean Welden, 18 years old, is a second year student at Bennington College (USA). On December 1, 1946, Welden informed his roommate, Elizabeth Parker, that she had taken a hike but was unable to return.

Authorities immediately launched a search on the 435-kilometer Long Trail that cuts through Vermont to the Canadian border, where some local witnesses reported seeing the girl.

However, they did not find any clues. Police then received information from a Massachusetts waitress who had served an excited girl, matching Paula’s identity.

Upon learning of this information, Paula’s father disappeared for 36 hours, supposedly to “follow the trail of his daughter”, but it was the strange move that made him the No. 1 suspect in the Paula disappearance.

Next, stories about Paula’s home life began to spread, almost as unusual as her parents told the police. Apparently, Paula had not returned home on Thanksgiving the week before, seeming to feel anxious about her dissonance with her father. Paula’s father, on the other hand, theorized that his daughter was “distraught by liking a guy so he must be a suspect”.

A decade later, a local man in the town of Bennington, Vermont, twice told his friends that he knew where Paula’s body was buried. However, he couldn’t bring the police in ?! With no evidence of crime, no body and no forensic clue, the incident has become increasingly mysterious, including those related to the paranormal hypothesis.

In 1900, the three lighthouses guarding the Flannan Islands, off the west coast of Scotland, suddenly disappeared in confusion. The lighthouse is overseen by a group of four including Thomas Marshall, James Ducat, Donald MacArthur and one person alternating from the shore.

On December 26, 1900, the fourth person took turns to the lighthouse but could not see the other 3 people. This person saw an overturned chair near the kitchen table. No body was found. It is believed that 3 people drowned, kidnapped by foreign agents, a ghost ship or giant sea monster. Until now, the secret is still buried.

13. The dog’s death bridge

The Overtoun Bridge, near Dumbarton – Scotland, seems to have the force of calling for dogs to plunge into death. Since the early 1960s, about 50 dogs have perished under this bridge and hundreds more have jumped down but survived. Below the Overtoun Bridge at an altitude of 15 m are jagged rocks.

The Scottish Association against Cruelty of Animals sent people to investigate, but to no avail. Scientifically, it can be said that dogs have the ability to “form suicidal intentions”. However, something was enticing them to jump off the bridge, often from the same spot and always on sunny days.

Many theories have come up, including the haunted bridge (which is popular after a local man threw his young son down the bridge and killed him in 1994), a weasel mark the area with a scent that attracts dogs or an unusual sound at the bridge that only dogs can hear.

14. “Monsters” are gray

The Big Gray Man is a mysterious creature believed to haunt the second highest peak in Scotland, Ben Macdui. In the native Scottish language, this creature is called Am Fear Liath Mòr.

Like the Yeti (snowman) of the Himalayas and the Big Foot (big-legged monster) in the Pacific Northwest, the Big Gray Man is confirmed to have been seen by several witnesses.

The appearance of this creature is not like a bear. Those who have seen the Big Gray Man describe it as tall (over 3 meters) and human-like with short hair, wide shoulders, and long arms. Nearly all of Big Gray Man’s appearances have been accompanied by the sound of gravel beneath its footsteps.

Scientists have yet to come up with an explanation for the Big Gray Man sightings and accompanying sound. Meanwhile, psychologists argue that those who are supposed to see and hear the Big Gray Man are in a state of physical and mental distress due to exhaustion or feeling alone.

15. The occult colony of Roanoke

In 1587, John White led a group of people from England to colonize on Roanoke Island, located in a chain of islands today known as the Outer Banks, North Carolina – USA.

White then leaves to find more supplies. But when he returned three years later, he found the colony abandoned, in which all houses and structures were carefully dismantled.

Before leaving Roanoke Island, White instructed the group from England that if they were captured by force, they had to carve a cross into a nearby tree but there was no cross. The only clue is from “Croatoan”, the name of an indigenous tribe allied with Britain. White understood this to mean that the group had moved to Croatoan Island (now known as the Hatteras).

Investigations conclude that the group was “slaughtered by the Powhatan tribe” but there is no archaeological evidence for this. Conducting a recent review of official sources, it was discovered that an earlier group of people might have been slaughtered rather than White’s.

Some hypotheses suggest that they and the Croatoans or local tribes have merged, but so far no evidence of DNA has been found to help identify their descendants. Scientists are still unable to explain this ocean mystery.

16. Circleville letter writer

In 1976, residents of Circleville City, Ohio – USA, received anonymous letters. They were postmarked from the city of Columbus in the same state, filled with harsh words.

The text of the letter reminds one of the alleged relationship between the school bus driver Mary Gillespie and the superintendent. A letter was sent to Mr. Ron, Mary’s husband, threatening his life if he does not end his love for his wife.

By 1977, Mr. Ron was killed in a suspicious car crash, including shooting. However, the local police chief said that Mr. Ron’s death was just an accident. After that, Circleville City residents began receiving letters accusing the sheriff of covering up the incident.

Letters continued throughout the 1970s and early 1980s, even after Ron’s sister’s husband, Paul Freshour, was found guilty of “writing letters and trying to kill Mary with a single gun. pistol”.

However, even when Mr. Freshour went to jail, letters still appeared. Mr. Freshour even received a letter from among them. In 1994, Mr. Freshour was released and died in 2012. The true identity of “Circleville Writer” remains in darkness. Some believe it is Mr. Freshour. Others suspect it is Mary, who used the letters to support her perfect murder of her husband.

17. The Tunguska Facts

On the morning of June 30, 1908, nearly 2,000 square kilometers of forest in Siberia – Russia was cut down by “an explosion”. There are no witnesses or evidence associated with this event. It was named “the Tunguska event”. Scientists classify it as a “collision event”, meaning that the collision can be recorded between two astronomical objects, such as an asteroid and the earth.

However, no craters were found in the “collision”. So scientists can only guess what happened, maybe an asteroid exploded on Earth, causing the aforementioned devastation in Siberia.

18. Flight MH370

On March 8, 2014, while flying from Malaysia to China, a Boeing 777 carrying 239 passengers and a crew member of the Malaysian Airlines airline suddenly disappeared.

One of the largest multinational search operations in aviation history found just 20 of the plane’s debris. Malaysia’s Prime Minister declined to comment beyond saying the plane had disappeared over the Indian Ocean.

Theories included, hijacked, captured by the US, crew committed suicide (there is information that the pilot is having a marriage problem), fire on a plane, plunging into the sea, natural Jelly attacks and even gets captured by aliens. But until now, this is still the biggest mystery in the history of modern world aviation.
