Dragon Boat Festival holiday, freeze-frame moment

  Editor’s note:It’s the Dragon Boat Festival again. Dragon Boat Festival is an important traditional festival in our country. In this festival, people either row dragon boats, make zongzi, hang calamus and insert mugwort, or take part in cultural activities and punch cards for tourism, so as to inherit the humanistic strength, cultivate the feelings of home and country and show the confidence of national culture in a traditional or fashionable way. This newspaper has launched the column @ Dragon Boat Festival Moment from now on, focusing on the wonderful moments of celebrating the Dragon Boat Festival holiday in all parts of our province. Please make a note.

  Anji dragon boat race between mountains and rivers

  Zhejiang Online June 23rd (Reporter Li Shichao Sharing Alliance Huzhou Xuchao)On the afternoon of 22nd, the Dragon Boat Race of the 5th National Fitness Festival in Huzhou in 2023 was held in Fu Shi Cun, Xiaofeng Town, Anji County. Eleven dragon boat teams from all over Huzhou competed fiercely, attracting a large number of spectators to watch the race.

  "Knock, knock …" With the sonorous sound of drums, the dragon boat players struggled to paddle in unison. Dragon boats rush out of the starting point like arrows leaving the string, and you chase after me and cut the waves, putting on a good show of "speed and passion" on the water. The exciting competition also ignited the enthusiasm of watching the game on both sides of the strait, and the cheers and cheers came one after another, which was very lively.

  "Every year, I will participate in the Dragon Boat Festival. This year, there is an Asian Games, which feels very different." After the game, Lu Hongquan, a member of Shuijingjing Nanxun Dragon Boat Team, said.

  Shi Cun is endowed with rich landscapes and pleasant scenery. "With the unique natural resources, we have been unable to find a transformation path, and the village collective income has always been very single." Zhang Wenze, secretary of the General Party Branch of Fu Shi Cun and director of the village committee, said that until 2019, the first dragon boat race was held in the village, which made the number of tourists in the village exceed 10,000.

  After that, Fu Shi Cun held a dragon boat race every year, and the village also set up its own dragon boat team, rescue team, training team and cheerleading team, showing a strong atmosphere in which all members participated in the dragon boat race. This year, the village created the theme activity of "Fun Stone Tour Xixi" in the crazy water-splashing season. During the whole summer water-splashing season, special water projects such as kayaking and paddle board were introduced to create a rural water park to attract tourists and promote the village’s collective income.

  Spend a holiday in Jiaojiang Art Museum

  Zhejiang Online June 23 rd(Reporter Chen Jiuren Sharing Alliance Jiaojiang Zhao Yang) On the evening of 22nd, the Jiaojiang Art Museum in Wenchuang Garden, Laoliangfang, Taizhou City was brightly lit, and people came to see the exhibition, listen to songs and go shopping in an endless stream. The first wonderful night activity of the art museum in Jiaojiang District is in full swing.

  In the art gallery, a large art exhibition is on display. On the floor of the exhibition hall on the third floor, two huge 3D realistic paintings attract people to stop and take photos.

  The lobby on the first floor of the art museum is full of children waiting to draw. Luo Pujian, president of Taizhou Cartoonist Association, and other four painters are painting comic portraits for the public.

  A lawn concert is being held at the Little Square outside the art museum. Next to it are experience activities such as printmaking, pottery, flower arrangement and paper cutting.

  "I hope there will be more such literary and artistic activities." Fan Fan, a citizen of Jiaojiang, specially came to see the exhibition with his son. Rich activities, let them have fun.

  According to reports, Taizhou Laoliangfang Wenchuang Park is a gathering place for creative design shops and a popular gathering place for Jiaojiang Night Economy. This year, Jiaojiang District launched the weekend art museum tour, with the art museum as the core, to create a normalized art activity that integrates teaching, interaction and display, and integrates garden and market.

  Yiwu foreigners go into battle to make dumplings.

  Zhejiang Online June 23 rd(Reporter Li Jiao Yan correspondent Fu Bolin) On the morning of the 22nd, the New Era Civilization Practice Institute in beiyuan street, Yiwu was very lively. The Neighborhood Festival "Chinese and foreign families welcome the Asian Games from" righteousness "and" Zongzi "is held here. More than 10 foreign friends from Pakistani, Israeli, Indian and other countries gathered with five groups of China families to appreciate the charm of China’s traditional culture.

  At the event site, Chinese and foreign friends immersed themselves in traditional folk customs such as dumplings, throwing pots and paper-cutting, and felt the beauty of Chinese culture. All of them had a great time. "This is my first time to participate in folk experience activities with China residents." Mimi, a foreign teacher in Yiwu, talked about her feelings about the Dragon Boat Festival, and thought that the traditional culture of China was very attractive, hoping to have a better understanding. As the highlight of this activity, the experience of making zongzi has become the most popular activity. The green leaves, white glutinous rice and long zongzi lines have stumped many foreign friends. Volunteers and China family members teach foreign friends how to make zongzi.

  "I hope that through this activity, more people will understand the traditional culture of China and feel the charm." The relevant person in charge of beiyuan street said. It is reported that beiyuan street has become a civilized person by building a "15-minute civilized practice service circle" with global coverage and ready access. Focusing on the theme of "Our Festival", it has concentrated on developing civilized practice in the new era, and is committed to creating a beautiful, harmonious and livable living environment for residents, spreading civilized ideas and carrying forward the new trend of the times.

Building a solid development floor, Yangzhou pushing hard nuclear policy measures, and comprehensively strengthening grassroots infrastructure construction

  The new Newcastle disease vaccine with gene VII is the first Newcastle disease vaccine with independent intellectual property rights in China, and it is also the first vaccine to effectively prevent and control Newcastle disease in geese, which can simultaneously prevent Newcastle disease in chickens and geese. At the beginning of this year, this achievement won the second prize of the National Technology Invention Award at the 2019 National Science and Technology Awards Conference.

  Leading this work is Liu Xiufan, an academician of China Academy of Engineering and a professor at Yangzhou University. He believes that human health, animal health and ecological environment health are a whole, and we need to practice the concept of "one health".

  Half a century of scientific research, "fighting" with animal diseases

  Liu Xiufan, who is 79 years old this year, still shows amazing scientific research creativity. He graduated from Subei Agricultural College in 1965, majoring in veterinary medicine, and has been "fighting" with animal diseases for more than half a century.

  One winter day in 1965, three cows "Baobei" of a production team in gaoyou county, Jiangsu Province suffered from organophosphorus pesticide poisoning, which made them seriously ill. After the diagnosis, Liu Xiufan, who just graduated and stayed in school, quickly removed the pesticides from the cattle and gave an antidote. A few days later, the poisoned cow recovered. "This is my first home visit after graduation. Simple farmers will not express their gratitude with too many words, but just hold my hand tightly and refuse to let go." Liu Xiufan said.

  In 1980, Liu Xiufan was selected by the Ministry of Education to go to the United States for further study, and successively studied veterinary biotechnology at Michigan State University and the Poultry Research Institute of the US Department of Agriculture. "When I first arrived in the United States, the director of the International Exchange Center, who helped me with the formalities, saw my resume and said that you studied veterinary medicine, so he called me Doctor and called other visiting scholars Mister." It was only this little bit unusual that made Liu Xiufan feel very happy at that time: "In foreign countries, veterinary medicine is a very respected profession, and it is great to study veterinary medicine."

  In addition to taking courses related to veterinary medicine, Liu Xiufan also specializes in the study of monoclonal antibodies against Marek’s disease in chickens. "In the end, I successfully developed a monoclonal antibody against Marek’s disease in chickens, which became the standard reagent for international serotyping." Liu Xiufan said that in less than three years after returning to China, he took the lead in applying monoclonal antibody technology to the research and control of animal diseases. "More than 100 kinds of monoclonal antibodies with different epitopes of seven pathogens such as Marek’s disease virus, Newcastle disease virus, Escherichia coli, Salmonella and avian influenza virus have been developed. The study of monoclonal antibodies not only fills the gap in China, but also reaches the advanced level of similar research in the world. "

  "Newcastle disease, commonly known as chicken plague, is one of the two most serious infectious diseases that endanger the global poultry industry, just like highly pathogenic avian influenza." Liu Xiufan said that the incidence and mortality of Newcastle disease is as high as 100%, and it has been listed as a legally reported animal disease by the World Organization for Animal Health.

  Liu Xiufan said that vaccine immunization is an important method to prevent and control Newcastle disease. The infection rate of Newcastle disease virus in chickens in China is high, and all chickens are vaccinated at high frequency. The most widely used is the gene II LaSota vaccine introduced from abroad. "However, since the 1990s, the epidemic characteristics of Newcastle disease in China have changed greatly, and atypical Newcastle disease is still common in chickens vaccinated with LaSota vaccine at high frequency."

  Grinding a sword in eighteen years to create the first Newcastle disease vaccine in China

  In the late 1990s, Liu Xiufan’s team launched an epidemiological survey to conduct molecular epidemiological research on Newcastle disease virus in China.

  "By analyzing the genotypes of more than 1,500 Newcastle disease virus isolates, we first discovered the genome length characteristics of Newcastle disease virus type VII, which proved that more than 95% of the virulent Newcastle disease viruses prevalent in chickens and geese are genotype VII, which has no host specificity and can be cross-infected." Liu Xiufan said.

  Why does gene ⅶ Newcastle disease virus cause a serious epidemic? Liu Xiufan’s team further revealed the pathogenic mechanism of gene VII Newcastle disease virus. "Gene VII Newcastle disease virus will cause serious damage to the immune organs of chickens and geese, leading to their immunosuppression. The commonly used LaSota vaccine does not match the genotype and antigenicity of gene VII Newcastle disease virus, and its ability to clear the virus is weak, resulting in the frequent occurrence of atypical Newcastle disease in chickens and the outbreak of goose Newcastle disease. " After finding out the culprit, developing a new vaccine as soon as possible has become a top priority for Liu Xiufan.

  Since 2001, from more than 200 epidemic strains of Newcastle disease virus type VII, the team has screened and obtained a strain with high reproductive titer, strong immunogenicity and good cross-protection in chicken embryos as a donor, constructed an infectious clone containing the full-length genome of the strain, and pioneered the reverse genetic technology platform for directly weakening the virulent Newcastle disease virus type VII in the world, breaking through the technical bottleneck that conventional means cannot weaken the virulent Newcastle disease virus type VII.

  In 2006, Liu Xiufan’s team successfully invented gene VII Newcastle disease vaccine strain A-NDV-VII, which is the first gene VII vaccine strain in the world and the first Newcastle disease vaccine strain with independent intellectual property rights in China. Compared with the performance parameters of the international common vaccine strain LaSota, the vaccine strain has weaker virulence and better immunogenicity, the titer of antibody produced after immunization is more than 4 times, and the virus removal ability is more than 10 times. It can be used not only for chickens but also for geese. "When the vaccine strain is created, we have the’ seed’ to develop the vaccine." Liu Xiufan said with a smile.

  Using the invented attenuated strain A-NDV-VII as seed virus, the team developed the first registered inactivated vaccine of Newcastle disease virus type VII in the world, which solved the major problem of Newcastle disease prevention and control in chickens and geese in China. In 2014, the vaccine obtained the national first-class new veterinary drug certificate. Since its introduction, the vaccine has produced and sold a total of 7.51 billion feathers, which has been popularized and applied in 31 provinces, municipalities and autonomous regions across the country, increasing the efficiency of aquaculture enterprises by more than 5 billion yuan and achieving remarkable economic, social and ecological benefits. "We should treat the health of the ecological environment as a whole." Liu Xiufan said.

  Human beings have gained experience in the struggle against previous plagues.

  The history of mankind is also a history of fighting the plague. Liu Xiufan said that in history, smallpox, plague, flu and other plagues have claimed hundreds of millions of lives and caused painful disasters to mankind. In the struggle against previous plagues, mankind has gained valuable experience and defeated the epidemic. In recent years, the emerging Nipah virus, SARS virus, MERS virus and highly pathogenic avian influenza virus have attracted great attention and attention. "We may face new viruses in the future."

  "When dealing with a new virus, we must first take quick emergency measures to control and eliminate the source of infection, cut off the route of virus transmission, protect susceptible groups, and prevent the spread of the virus from expanding." Liu Xiufan said that at the same time, it is necessary to systematically carry out epidemiological research, pathogenic mechanism and immune mechanism research, and carry out joint research to develop new diagnostic methods and effective prevention and control products.

  Liu Xiufan said that the H7N9 subtype avian influenza virus that appeared after 2013 infected people. The virus was the product of multiple subtype avian influenza viruses, and its internal genes were all derived from H9N2 subtype avian influenza virus. "Although the probability of infection with avian influenza virus in the exposed population is very low, we must strengthen the monitoring of avian influenza virus to prevent the virus from mutating and spreading from person to person, triggering a new influenza epidemic. Therefore, the control of avian influenza is not only economically important, but also plays an important role in public health. "

All the system chips are self-developed. What road will Huami take?

Original attention to cutting-edge technology qubits is included in the topic # Huami 1# Chip 4# The technology circle is paying attention to 70.

Yang Jing is from Hefei

Quantum bit report | WeChat official account QbitAI

If it weren’t for being in Hefei, I would have thought it was a release conference of a song by a certain Vida.

At the beginning, the CEO came straight up with a huge wafer.

This big disc is engraved with 4000 chips made by ourselves.

In the next hour, it was even more confusing. Four shots were fired in succession, and the technique was very vertical.

There are chips, operating systems, AI algorithms, and MRI nuclear magnetic resonance equipment.

If I want to say again, this is a press conference of watch factory, I don’t believe it myself.

The conference of "Watch Factory"?

As you may have guessed, it is Huami, a watch factory headquartered in Hefei.

It made its debut in mi band, and then became the fastest-growing wearable manufacturer representative in NYSE with its endless product strength.

Chip has become the traditional artistic ability of Huami. In 2018, Huami bet on RISC-V architecture and launched the first AI chip in the field of smart wearable in the world-Huangshan No.1, which was mass-produced in the following year. Last year, at Huami’s first non-product conference, Huangshan No.2 chip was unveiled.

As the first launch of this conference, Huangshan 2S chip is called 2S, but it is not a simple improvement of the second generation.

It adopts dual-core RISC-V architecture. Among them, the large-core system can perform high-load calculations such as graphics and UI operations, and also integrates FPU to support floating-point operations. The small core, on the other hand, has low power consumption, and can process sensor data for 24 hours to realize continuous monitoring of biological data all day.

Large core and small core, clear division of labor, achieving a balance between computing power and power consumption.

Compared with the previous generation chip, the computing efficiency of Huangshan 2S is improved by 18%, the running power consumption is reduced by 56%, and the sleep power consumption is reduced by 93%.

Three years, three chips, realize the transition from usable to easy to use. The core-making project of Huami has entered the fast lane.

In addition to the chip, there is Zeppos, the native smart watch operating system that debuted.

As another field that is difficult to overcome in the intelligent hardware industry, the reason why Huami has to do it is also because of user demand and market drive.

There are two mainstream operating systems on the market at present. Either it is based on the mobile phone system magic change, but it is too cumbersome and complicated for wearable devices.

Either it is a ready-made embedded real-time operating system, which is more suitable for industrial control equipment and ordinary IoT products. It is directly used in smart watches that pay attention to experience, and some of them are not acclimatized.

Therefore, if Huami wants to do OS, there are two requirements first: lightness and user experience.

In terms of memory, the bottom layer of Zepp OS system is based on FreeRTOS micro-kernel open source code, which takes up very little space, and the system package is only 55MB, which is about 1/28 of Apple watch OS.

In terms of battery life, the running power consumption of Zepp OS is 65% lower than that of the previous Amazfit OS, thus ensuring continuous health data monitoring for 7×24 hours.

For developers, Zepp OS is also equipped with a watch applet framework-Zeus mini-program framework, which is convenient for developers to develop applets with a lower threshold.

In addition, the system also integrates 150 dials, including 15 dynamic dials. According to reports, the graphical development environment will be opened in the future, and individual users can also participate in the dial design.

In addition to the appearance of software and hardware, there is a brand-new AI algorithm-Pump Beats blood pressure monitoring engine. As a function with the highest voice in the whole conference, it can directly solve the current needs.

The smart watch equipped with this engine can measure blood pressure with one button in 30s. At present, Huami has started clinical experiments with the First Hospital of Peking University, and it is expected to be available in the fourth quarter.

According to the Report on Cardiovascular Health and Disease in China in 2020, there are as many as 245 million patients with hypertension in China, of which the adult prevalence rate is 23.2%. In recent years, the number of deaths related to hypertension is as high as 2 million every year.

After more than five years of research by Huami team, this engine has taken an important step in the field of non-invasive and sleeveless blood pressure measurement technology.

At the end of the conference, it also showed the latest medical field exploration promoted by Huami through investment-portable MRI (nuclear magnetic resonance) equipment, which corresponds to medical pain points.

Traditional medical MRI is a huge thing with high cost and high environmental requirements, and it is often hard to find a machine, so patients need to make an appointment a long time in advance.

Portable MRI not only occupies a small area, but also does not need a special shielding room. Compared with traditional high-magnetic MRI, portable MRI can achieve high-quality imaging at low field strength even when the signal-to-noise ratio is 300 times different.

Regardless of Huangshan 2S chip, Zepp OS, PumpBeats blood pressure monitoring engine and portable MRI (nuclear magnetic resonance) equipment, Huami’s various release actions have shown that the core of the enterprise adheres to: global self-research.

How did Huami embark on this road?

As early as 2015, Huami layout chips began to have a fixed number, but now with the maturity of technology, this road has gradually become clear.

Simple eight-word summary: global self-research and pursuit of the ultimate.

Chip is the extreme of hardware, operating system is the extreme of software, and the pursuit of AI system is the extreme of algorithm.

With the appearance of the operating system, Huami has opened up a global self-research from chips, algorithms to operating systems.

In fact, this path of self-research from chips, OS and algorithms is not unfamiliar. For example, Apple and Huawei.

Apple built S5 and S6 chips and Watch OS for Apple Watch.

Huawei has Kirin A1 chip and the newly launched HarmonyOS system.

The advantages of doing so are obvious. Combine software and hardware, and use your own chip to adapt to your own software ecology.

Manufacturers have great autonomy, no invisible constraints, and can customize product functions to form their own product strength.

In recent years, Huami has applied for more than 1,000 patents, of which invention patents account for half.

The ultimate in technology means the growth of R&D investment in Huami.

In the last three years, Huami’s average R&D investment has reached 410 million yuan every year. In 2020, R&D investment will reach 538 million yuan.

This kind of investment is equivalent to 2 times or even 3 times that of some emerging Internet companies and IoT intelligent hardware companies.

With such a big investment and pursuing the ultimate in technology, what does Huami think?

Considerations behind global self-research

First of all, the so-called knowing people and discussing the world is closely related to the development stage of the industry.

The first stage, let’s call it the mode verification period.

Back in 2013, Samsung released its first smart watch, Galaxy Gear, and officially entered the wearable field.

However, due to poor performance, it has been criticized a lot, so there is not much spray.

In the second year, Huawei, Apple and Xiaomi collectively entered the market, which really set off a wave of smart wear in China.

At the beginning of 2014, Huawei released the smart bracelet TalkBand B1 at the Mobile World Congress, which started the first shot.

In September, Apple released the Apple Watch, and then kept the frequency one more time a year.

It was also this year that Huami and Xiaomi joined hands and became an explosion through a cost-effective smart bracelet.

Huami also became famous in World War I and established its status as a river and lake.

Prior to this, the prospect of smart wearable was still in doubt. But when the explosion comes out, there is no doubt about the business prospects.

From 2015 to 2020, the market size of smart wearable devices industry in China increased from 11.48 billion yuan to 63.22 billion yuan, with a compound annual growth rate of 40.7%.

More importantly, smart wearable is widely regarded as the next growth point in the field of consumer electronics after mobile phones.

So the second stage-short and fast replication period-also came.

Now that the smart wearable Qian Jing and its prospects have been verified, and as a new growth point of consumer electronics, it is inevitable that new players will flood in and giants will copy quickly.

Smart wearable copying is actually simple and direct, and the advantages are obvious-you can take the volume quickly, you can make large-scale profits after taking the volume, and you can still make quick money.

However, shortcomings or hidden concerns are naturally obvious.

Low prices are cool for a while, but who is still alive by low prices in the field of mobile phones? The doctrine of taking is very easy to use. Isn’t the risk of getting stuck in the neck and cutting off the confession direct enough? Finally, following the trend of homogenization, you can only live in the shadow of "cottage" forever.

Therefore, for smart wearable manufacturers, or consumer electronics companies, there are opportunities to stand out from the crowd during the pattern verification period and the short and fast replication period.

But if we want to operate sustainably, make it bigger, deeper and longer-term, we must build our own moat.

For example, Amazon and JD.COM in the e-commerce industry also had their previous growth periods, but later decided that their ability to go deeper and further was self-built logistics of "humiliation and burden-bearing".

Self-built logistics undoubtedly requires a large investment, and it will also focus on the whole company and business, which runs counter to the "light assets" advocated by technology Internet companies.

However, it is self-built logistics that has become the guarantee for Amazon and JD.COM to build a long-lasting business and provide better and longer-tail services.

It has become a moat that truly enables enterprises to operate sustainably.

For the current smart wearable industry, for Huami, isn’t the global self-developed chip and system just "self-built logistics"? Isn’t it to build a moat for the long term?

In fact, if we return to the company’s goals, especially the pressure of regular financial reports faced by listed companies, it may not be an easy way to do research on the whole stack.

However, even under such pressure, Huami still chose the self-developed system and chip, and insisted on the difficult and correct road, which shows its ambition and its long-term ambition.

On the other hand, from the perspective of users and consumers, a consumer electronics company that has proved that its actions will continue to provide long-term value is a company that will be trusted.

Nowadays, Huami is naturally a vertical champion in the wearable field, but don’t ignore that the global giants like Apple are racing together on this track.

Competing with a company like Apple can only run like water. It’s not a matter of time, but a matter of time.

Only by going deep into chips and systems can we have the qualification and ability to talk endlessly.

From this perspective, the road of Huami is no longer difficult to see through.

How to evaluate the way of huami?

Look back at Hua Mi’s movements.

From a technical point of view, Huami has done more and more "deep", from chips and systems to consumer brands. Nowadays, in addition to Amazfit, there are Zepp, and there are related OEM businesses upstream.

Forming a closed-loop technology will certainly highlight the product strength of Huami more and more, enhance the brand effect and expand the benefits.

Does that mean that Huami has to take a closed road?

On the surface, it is, but it is not.

On the one hand, based on the current business needs, Huami needs to open its products to the outside world after reaching a certain level.

At the press conference, Huang Wang announced that he would open the chip and operating system to third parties through Yitong Technology.

The products pass the stage of practical verification, providing solid evidence for Huami technology, which is conducive to building brand trust in the industry and more conducive to the healthy development of the whole industry.

On the other hand, from the perspective of the industry, global self-research represents Huami’s determination to deepen the health field.

As mentioned before, with the intensification of industry competition, other competing products are caught in the whirlpool of low-price competition, system takenism, homogenization function, etc., but there is still more potential hidden behind the fog in the field of healthy wear, which has not yet been developed, which requires industry entrants to concentrate on exploring more integration points between technology and human needs.

In this matter, Huami will go her own way.

This can explain why Huami is not only self-researched, but also hopes that some IoT partners such as smart door locks, smart cars and sweeping robots will participate, and finally connect the whole ecology through opening ports. In fact, the Zepp OS operating system of Huami’s conference can support the entire RISC-V ecosystem.

To some extent, smart wearable is just a representation, and the value of Huami lies in pushing the health industry forward.

Numerous industry stories in the past have long shown that if an industry or field wants to develop healthily, it is far from enough to rely only on cross-border systems and marketing methods. What will wearable health equipment look like for you and me in the future?

Need Huami, and even more enterprises to explore the possibilities of the industry to participate.

A trillion wonders city, will it become the biggest unfinished building?

Original Bund Jun Bund TheBund

Saudi Arabia is building a

Super exaggerated linear city

Such a sci-fi picture

I’ve only seen it in movies

It is my pyramid and will go down in history forever.

What makes Saudi Crown Prince Mohammed bin Salman sigh so much is an exaggerated building-perhaps it is more appropriate to call it "the city" directly.

Just last week, Saudi Arabia officially announced an architectural plan called "The Line", which exploded in the global architectural circle.

This straight "line" is located in the northwest of Saudi Arabia, starting from the Red Sea, with a length of 170 kilometers, a width of 200 meters and a height of 500 meters, covering a total area of 34 square kilometers.

To put it simply, two super-long glass skyscrapers are parallel, and an entire city is sandwiched between them.

It will also become an important part of Neom, a new city in northwest Saudi Arabia.

Such a crazy architectural idea, which we only saw in science fiction movies before, is now going to become a reality?

But don’t be too happy, even in Saudi Arabia, which is "rich to the brim", it is not easy to build such a behemoth.

In recent years, Saudi Arabia has competed with Dubai, United Arab Emirates, and wants to seize the name of "the most luxurious in the world" by countless grand and futuristic wonders.

These renderings are really beautiful, but what is the probability of completion?

01

A super-long linear city

The Line project is designed by American firm Morphosis, and the budget will reach an astonishing $1 trillion, which will be completed in 2030.

Such a huge volume, if calculated by a single building, will undoubtedly become the largest building in the world after completion.

Ben Salman said that The Line provides a brand-new concept of urban planning and design.

"The vertical hierarchical distribution of urban functions allows people to travel seamlessly in three-dimensional space, which we call’ zero gravity urbanism’."

Different from the layout of traditional cities radiating from the city center, The Line City, as its name implies, brings all functions together in this straight line.

Two super-long skyscrapers with a height of 500 meters enclose the outline of the city. By then, they will surpass our world financial center (492 meters) and become the 12th tallest building in the world.

The building extends all the way from the red sea to the mountains, 800 meters from the mountains, and then continues to extend to the desert. Because the surface of the building is covered with glass curtain wall, it is also called "Mirror Line", which is full of science fiction.

The 200-meter-wide area between the two buildings is the public area of the city.

These functional facilities are all three-dimensional-vertical farm layered farming, connecting canteens and kitchens, making urban residents’ food baskets self-sufficient; The stadium is located at a height of 305 meters, and residents run, play ball and have fun in the sky.

02

NEOM, the new future city of Saudi Arabia

Another major feature of The Line is environmental protection. It is completely powered by renewable energy. 95% of the land is divided into nature reserves, where sunlight, plants and natural ventilation are balanced.

There are no roads and private cars in this city, and countless sidewalks and bridges connect two buildings.

People can walk to the public station they want to go to in 5 minutes at most, then take the high-speed train to their destination and reach the other side of the city in 20 minutes.

When completed in 2030, The Line will welcome the first batch of 1.5 million residents. In the later stage, we will gradually expand and improve the functions, and increase facilities such as houses, shopping malls, parks and schools, which can accommodate up to 9 million residents.

For Saudi Arabia, this is actually very important, because it is also one of their original intentions to build a new future city NEOM in the northwest, and The Line is an important part of this new future city.

NEOM covers an area of 26,500 square kilometers. In Ben Salman’s vision, it will become a place where everyone in the world can leave their footprints with creativity.

"The world is facing an environmental crisis, and NEOM can provide the most imaginative solutions. We have a team of the brightest talents in engineering and architecture to realize these cutting-edge ideas."

Environmental protection is a signboard with great communication value, but it is not the whole of NEOM. With a huge investment of trillions of dollars, the crown prince is not thinking of doing "charity" for environmental protection.

As early as 2016, Saudi Arabia issued the so-called "Vision 2030", with the goal of diversifying the Saudi economy and getting rid of its dependence on oil.

NEOM, the new future city, is a trump card of Vision 2030.

The Line alone can provide 380,000 new jobs, and it is expected to provide Saudi Arabia with a gross national product of 47.9 billion US dollars by 2030.

03

What is the probability that the spectacle will end badly?

In the "Vision 2030", the big goal is ahead, and now Saudi Arabia is building a lot of buildings, and exaggerated projects are one after another.

Besides NEOM, another most famous project in Saudi Arabia is the Red Sea Project, which will be an important step for Saudi Arabia to become a "global luxury tourist country".

500 kilometers north of Jeddah, Saudi Arabia, a super-large luxury resort will be built, and 22 brand-new islands will be built on the Red Sea.

The participating big-name design firms include Kengo Kuma, Foster+Partners and Killa Design, and they will build a large number of seascape villas and desert tents on these islands.

In addition, they have signed contracts with 12 luxury hotels including Ritz-Carlton Seclusion, Magnificent, Liushan, St. Regis, Raffles and Addison. Magnificent and Ritz-Carlton Seclusion are scheduled to be completed and opened by the end of next year.

Building luxury hotels and wonders everywhere, wrestling with rivals such as the United Arab Emirates, and now the $1 trillion The Line is launched …

Is Saudi Arabia really so rich?

Of course, Ben Salman has his own small abacus, attracting investment all over the world with renderings, and plans to list NEOM in the new future city in 2024 to attract more investors.

But the problem is that the Saudi Crown Prince has a bad reputation in the West.

In particular, in 2018, his approval of the execution of Saudi journalist Kachouqi was exposed, which was widely resisted by the international community, and foreign investors in Saudi Arabia even withdrew their funds.

As a result, many magnificent buildings in the original plan were forced to stop the progress of the project, and even have been unfinished.

One of the most famous examples is the "Jeddah Tower" in Jeddah, which started construction in 2016 and has a design height of 1,008 meters. It is planned to surpass the Burj Dubai as the tallest building in the world.

Unexpectedly, in January 2018, construction workers suffered a collective strike of unpaid wages, reaching a height of 600 meters and stopping.

Originally expected to be completed last year, there is only a semi-finished product until now.

Today’s The Line is actually not optimistic about the outside world after the design scheme is announced, and some people even predict that it will be "a bad end".

On the one hand, the reason for funds is that the construction and implementation are too difficult.

For example, it is necessary to drill through the mountains and dig a huge tunnel with a length of 800 meters and 30 floors to let the skyscrapers pass.

In addition, high-rise buildings will be built on the ground in the desert where there is nothing, and 10 huge mansions will be built …

By 2030, can this imaginative "line" really end successfully?

2024 Cross-border E-commerce Hot Start SHEIN Flexible Manufacturing Helps Sellers’ Product Innovation to Go to Sea

Xinhua Finance Shanghai, February 18 (Reporter Gao Shaohua) On the 18th, the reporter learned from the cross-border e-commerce platform SHEIN that cross-border e-commerce got off to a hot start in 2024, and China sellers seized the New Year business opportunities on the SHEIN platform, and some sellers doubled their sales of explosive products in the first year. The flexible supply of SHEIN accelerated the sellers’ product innovation to go to sea.

In the past year, 1.83 trillion yuan of goods in China were exported to the global market through cross-border e-commerce, an increase of 19.6%, reaching the level of 2.3 times that of five years ago. Entering the new year and spring, the business opportunities of bonus window opened to China sellers in overseas markets continue to be released.

At present, the growth rate of global retail e-commerce is much higher than that of offline retail, and overseas consumers’ shopping has accelerated to online transfer. According to the report of Satista, a global professional research data statistics company, the sales of e-commerce in emerging markets such as India, Brazil, Argentina, Turkey, Mexico, Russia, South Africa and Italy have all increased by more than 10%, and the global retail e-commerce sales will exceed 6 trillion US dollars in 2024.

As online shopping has become fashionable in overseas emerging markets, many people have changed from attending shopping festivals only a few times a year to spending on e-commerce every day or week. According to the latest list released by the authoritative organization PYMNTS, China’s cross-border platform SHEIN has reached the Top1 of the global shopping application ranking list, which is the sixth consecutive month that SHEIN has topped the list. SHEIN’s increasing market coverage and user influence overseas have also brought broad opportunities for domestic cross-border sellers to go to sea in the New Year.

"In January 2024, the company’s overall sales volume was quite good. The sales volume of several styles doubled compared with last year, and several single products rushed to the top of the sales list." Yin Fangfei, the seller of SHEN jewelry, used to supply short-sighted products to online celebrity in China for a long time. Since she settled in SHEN, she has taken the initiative to pay attention to overseas fashion trends and characteristics of explosive products, and referred to the methodology of "flexible production" and "quick response to small orders" that SHEN is good at, and organized the production of her own factory by using the digital background of the seller, which greatly improved the flexibility of the supply chain.

The children’s dress suit designed by Zhang Linlin, a Guangzhou seller, has become an explosion in the European market in late winter and early spring, and many new products have sold hundreds of pieces just after they were put on the shelves. Zhang Linlin is an expert in children’s wear and dresses. She entered the SHEIN platform a year ago. SHEIN faces more than 100 overseas multi-style consumer markets, creating many possibilities for her products to innovate and try. She said: "We can cover different festivals in different countries to do product development and design, not just in the Spring Festival, but almost all the year round after cross-border."

At present, China’s cross-border e-commerce sales network covers more than 220 countries and regions around the world, with more than 2,400 overseas warehouses covering an area of more than 25 million square meters. Third-party service providers such as logistics, payment and express delivery serve hundreds of thousands of customers around the world. All these infrastructures are helpful for China businessmen to go out to sea for gold. At the same time, many local governments have introduced a number of welfare policies to help accelerate the development of cross-border e-commerce industry, and the "one-stop" empowerment system provided by cross-border e-commerce platforms to cross-border e-commerce sellers is also accelerating.

"At first, our estimate of inventory was conservative and we underestimated the rapid sales of SHEIN." A Zhejiang seller who opened a shop on SHEIN said, "Since then, we have improved our inventory control. In order to meet the demand, we specially designed and launched hundreds of new styles for SHEIN." He believes that SHEIN employees have given the factory a lot of guidance on overseas consumption trends, which has brought great help to the company. Only by knowing how to improve the production accuracy and product quality according to the actual needs of the market can sellers continue to win the hearts of consumers.

In some industrial belts where sellers of SHEIN platform gather, SHEIN employees will also provide guidance or support for local sellers in product shooting, and also organize professional training for some local e-commerce photographers.

For consumers, the types of products they buy from the SHEIN platform are also more abundant. Statistics from overseas institutions show that among American fashion online shoppers, nearly 70% are familiar with SHEIN, and nearly one-third of them like this China company established in 2008. Judging from the usage share and social popularity index, SHEIN has won the preference of most American fashion online shopping consumers.

The collapse of Huang Lei’s human setup: from "housework male god" to "siege" of netizens

In the bizarre entertainment circle, the star’s every move often leads to heated discussion. Recently, Huang Lei’s image seems to be facing collapse, and the comment area has fallen. Once upon a time, he was the "Yellow Chef" with warm sunshine, and brought the audience wonderful memories of home cooking in "A Life I yearn for". However, with the rise of "Archaeological Tide", all the past things were rediscovered, and the people in Huang Lei became confusing. He has suddenly become the target of public criticism from a highly appreciated "housework male god", which has aroused deep thinking and discussion among netizens.

When it comes to Huang Lei, people may think of his excellent cooking skills and the warm atmosphere created in the program for the first time. He once served as a "God Chef" in the multi-season "Life of Desire", and these beautiful pictures have long been deeply rooted in the hearts of the audience. However, with the wave of "black history" being dug up, the glorious moment of the past was broken, and the image of Huang Lei began to be doubted.

In particular, the "stewed bean incident" has become the focus of hot discussion among netizens. When Song Dandan visited the mushroom house, the stewed beans prepared for her by Huang Lei caused a joke of food poisoning. Although the program group did not explicitly say that the responsibility lay with him, netizens did not buy it, and they used the social platform "archaeology" to question his cooking level. This incident has made many people begin to reflect: Does this former "housework male god" really have excellent cooking skills? Or just rely on the aura set by people?

In addition to stewed beans, the pot-stewed pork made by Huang Lei in the program also attracted a lot of controversy. Netizens joked that its content really didn’t match the name and doubted the degree of care in the production process. Put a bunch of hawthorn, there is no shadow of meat at all, is it a poorly designed pot-wrapped meat? Many people ridiculed: "Is this pot-wrapped meat originally intended to be made into pot-wrapped hawthorn?" These ridicules seem to have aggravated netizens’ doubts about his cooking.

And Huang Lei’s attitude in the program is also embarrassing. He often makes fun of Shen Teng, and his attitude seems to be complacent, and he doesn’t seem to care about the evaluation of the outside world. This randomness revealed the estrangement between him and the audience to some extent, and even attracted Shen Teng’s aggressive response, which made people question his attitude towards life. Someone bluntly said, did Huang Lei secretly set a trap at the scene and let Shen Teng take the blame for his dishes? This disturbing little detail makes people wonder whether the former "God Chef" is slowly losing its true self.

In addition, He Jiong, who is in obvious contrast with Huang Lei, praised Huang Lei’s cooking blindly in the program, but it seemed hypocritical. Such praise, it seems, not only failed to enhance Huang Lei’s image, but gave people a feeling of being late. The gap between overly optimistic evaluation and real word of mouth makes the audience’s trust in Huang Lei gradually weaken.

Huang Lei’s example can’t help but make people think, the peak of a star is often very short. Over-reliance on people’s design without perfecting one’s inner self may eventually end in collapse. Just like Huang Lei, blindly catering to the expectations of the outside world may not be able to win long-term popularity and love. With the questioning of people’s design, many viewers began to re-examine the reality and illusion of entertainment circle. The expected perfect people’s design is actually an illusion. They also realize that stars are ordinary people, and it is inevitable that they will make mistakes. Everyone should be more tolerant of them.

As this incident shows, Huang Lei’s story is not only his case, but also a mirror of the whole entertainment circle. Perhaps, after experiencing doubts and confusions, the stars can better understand that if they want to gain a firm foothold in this industry, they must have real talents and practical knowledge, rather than relying on a makeshift person.

Finally, the collapse of Huang Lei’s man-made device triggered a wide discussion among netizens, but we also expect him to stand up again after the storm and bring more surprises to the audience. In this highly competitive entertainment circle, it may not be possible to gain a foothold for a long time only by abusing people’s equipment, and the transparency and truth in facing the audience will be truly recognized. In short, stars need to face up to their own shortcomings and actively show their true side, so as to be more stable in the future.

In daily work and life, using technology and AI to help themselves may also be a direction for Huang Lei people to reshape their personal design. Using advanced AI tools, such as Sohu Simple AI, can help improve creative efficiency and free up more time to focus on your true self.

The Biden administration imposed tariffs on imported goods from China, and the American business community repeatedly expressed dissatisfaction.

On the 14th, the United States released the results of the four-year review of China’s imposition of tariff 301, announcing that on the basis of the original tariff 301, it would further impose tariffs on electric vehicles, lithium batteries, photovoltaic cells and other products imported from China.

After the news came out, many business people and business groups in the United States expressed their dissatisfaction.

In a statement to CBN, u.s.-china business council, a group of 270 American companies doing business in China, expressed disappointment with the results of the four-year Section 301 investigation announced by the Office of the US Trade Representative (USTR).

USCBC said: "We are disappointed with this result, because maintaining the previous tariffs (without lowering them) and imposing additional tariffs will eventually make it more difficult for American companies to compete at home and abroad. This will lead to fewer jobs in the United States. In the context of continued inflationary pressures, this will also raise the US consumer price index. "

Earlier, China’s Foreign Ministry spokesperson Wang Wenbin said at a regular press conference on the 15th that according to Moody’s company’s calculation, American consumers bear 92% of the cost of levying tariffs on China, and American families increase their expenses by $1,300 a year.

Liu Bin, a researcher at university of international business and economics School of Government Administration and China World Trade Organization Research Institute, said in an interview with China Business News that (compared with Trump’s tariffs on China), we can see that the industries and products subject to tariff increase are relatively concentrated, and the tariff collection quota has been greatly adjusted. For emerging industries, especially new energy vehicles, the United States has a strong intention to restrict or restrict development.

American consumers pay the bill?

On 14th, KenGriffin, American billionaire and founder of Citadel, said at a forum in Qatar: "Imposing high tariffs on China electric vehicles with low price and high quality, which are beneficial to American consumers, is another manifestation of the discontinuity of Biden’s economic strategy."

The National Retail Federation (NRF) is also "very disappointed" with the Biden administration’s move, and said that "as consumers continue to fight inflation, the last thing the (US) government should do is to impose additional taxes on imported products, which will be paid by American importers and ultimately American consumers".

Recently, Goldman Sachs said in a report that "tariffs in 2018-2019 have significantly increased consumer prices" and that these price increases were "almost entirely borne by American enterprises and families", not China exporters.

Goldman Sachs estimates that every one percentage point increase in the effective tariff rate will directly reduce the gross domestic product (GDP) of the United States by 0.03%, increase consumer prices by 0.1% and keep inflation rising for one year.

Sweet, chief American economist at Oxford Economic Research Institute, said that the political significance of tariffs is usually greater than the economic significance.

Sweet said: "Most economists think that tariffs are a bad idea, because tariffs will hinder a country from benefiting from specialization, disrupt the flow of goods and services, and lead to improper allocation of resources. When implementing tariffs, consumers and producers often have to pay higher prices. "

The new york Federal Reserve also found that tariffs in 2018 cost American families $419 a year due to increased tax burden and loss of market efficiency. The researchers estimate that this figure has doubled as other tariffs take effect in 2019.

Economists wrote in a working paper published by the National Bureau of Economic Research in January 2024 that the net economic impact of import tariffs, retaliatory tariffs and agricultural subsidies on American employment and enterprises is "at best ‘ Rinse ’ Look, and it may be a slight negative impact. "

The above-mentioned researchers said in this working paper that trade friction does seem to bring political benefits and strengthen the support of the Republican Party in the heartland of the United States and the communities most affected by tariffs. "Residents in areas protected by tariffs are unlikely to identify themselves as Democrats, and they are more likely to vote for Trump. Therefore, despite the high economic cost of tariff protection, voters seem to have given a strong response. "

American industry demands competition.

Recently, U.S. Treasury Secretary Yellen frequently appeared in the media to explain the tariff increase policy, but during the interview, she also repeatedly faced questions about whether the tariff increase would drive up prices, including "China’s electric cars are cheaper, so if more people (in the United States) buy them, wouldn’t it help solve the climate change problem".

In this regard, Yellen explained that with the accumulation of experience in producing these products by American companies and the development of newly built battery factories in the central and western regions, the price of automobiles will drop.

However, I am afraid that the industry has different views. CarlosTavares, CEO of Stellantis, a global automobile manufacturer, said that raising tariffs would not protect his company. He believes that "the only choice is to continue fighting", so the only way to compete fairly is to reduce costs and provide electric vehicles at more affordable prices.

In fact, there have been many cases before that prove that imposing high tariffs cannot promote the development of domestic enterprises in the United States.

In 2002, the United States imposed tariffs on imported steel and aluminum products. Subsequent studies showed that although this only caused economic losses of about $30 million, it led to an increase in the price of the steel consumption industry in the United States, and led to a sharp decline in employment opportunities in the entire steel industry, especially those small enterprises that did not have market power to influence prices.

In 2009, the United States imposed tariffs on tires imported from China. The Peterson Institute for International Economics found that this move was thought to have saved about 1,200 jobs in the tire manufacturing industry in the United States, but it cost Americans $1.1 billion in the form of rising prices.

A veteran who has been engaged in the import and export industry in the United States for a long time told the First Financial Reporter that in his view, the United States’ practice of adjusting tariffs this time is more posturing than actual impact.

Taking the solar panel products he is very familiar with as an example, he told reporters that before this adjustment, the solar panels imported by the United States from China had been greatly reduced due to anti-dumping duties: most of the solar panels on the American market were imported from Viet Nam or Thailand, and very few were directly imported from China. In fact, since last year, thousands of containers of related enterprises in China have been detained at the American terminal, and related enterprises may have paid millions of dollars in yard fees at the terminal. The current policy of the United States clearly shows that in order to enter the American market, these companies must set up factories in the United States.

However, in view of some cases that have happened, the prospect of setting up factories in the United States is not optimistic. "If the United States does block the import channels from Vietnam, I can’t imagine where American solar panels will be imported. But it seems unrealistic to rely on solar panels produced locally in the United States. " He added that many media in the United States have also questioned this, and they don’t understand why the import of clean energy products from China should be prevented, especially in the context that the US government has been advocating these clean energy technologies.

Cui Fan, a professor in the Department of International Trade of university of international business and economics Institute of International Economics and Trade, also told China Business News that Biden’s government has begun to contain the overseas investment of China Photovoltaic.

He explained that on April 24, the United States began the photovoltaic double-reverse investigation procedure for Vietnam, Cambodia, Malaysia and Thailand. It is expected that the preliminary ruling will be made this year and the final ruling will be made in the middle of next year. At present, the dumping margin of the four countries listed in the application for investigation ranges from 70.35% to 271.45%, which once blocked the photovoltaic exports of the four countries to the United States.

What needs to be noted is that after the United States announced the imposition of tariffs on China, the EU side, which is conducting countervailing investigations on China’s electric vehicles, is more cautious.

In an interview with China Business News, Liu Bin said that the US tariff increase on China may have a demonstration effect on the EU. However, unlike the United States, the trade links between China and Europe are closer, and the EU is more dependent on the China market.

Liu Bin said that at the same time, China’s new energy vehicles have entered the EU market, which has a "first-Mover advantage". Therefore, it is unlikely that the EU will adjust tariffs on a large scale and in a high amount like the United States. However, the EU may stand in a higher position and adjust taxes in the name of environmental protection.

The 3-year-old girl was found missing for 15 hours and slept alone by the wild grave for one night.

  A 30-cm-wide road behind the house almost became a permanent pain in parents’ hearts.

  At 6 o’clock in the evening the day before yesterday, a little girl less than 3 years old in Lin ‘an, Hangzhou, took this road, turned and went away … … She may have been attracted by the bamboo shoots that just popped up by the roadside. She walked and watched, and went further and further, plowing roads and loess roads. At last she got lost, which was a mountain she had never been to.

  Fortunately, at 9 o’clock yesterday morning after a whole night, she was found by search and rescue personnel, unhurt and in a normal mood. She was even asleep when she was found.

  Grandparents, mom and dad, and grandma who arrived from Yiwu cried like tears.

  Nearly 1000 people participated in the search and rescue of the little girl, and a large number of them went spontaneously after seeing the news on the Internet. How did a three-year-old girl get lost? How did she come over on a cold night in the mountains?

  7 minutes

  3-year-old girl disappeared

  Li Yue (a pseudonym) arrived at her mother’s house in Luojiwu Natural Village, Langjia Village, Lin ‘an, Hangzhou at noon on March 27th with her daughter Duoduo (a pseudonym) who is less than 3 years old. A few days ago, she made an appointment with her mother to make Qingming Guo (a kind of food) — — Making rice dumplings is a way for every family to live in Tomb-Sweeping Day.

  At 6: 00 pm, villager Jiang Zhongxiao went to work at night shift. When he passed by, he saw Duo Duo playing at the door, with rice husk in his hand.

  "The adults are here, and my mother also urges me to eat early so that I can take my children back early." In pheasant dock village, Li Yue told Qianbao that she went to add a bowl of rice and just ate a few mouthfuls, only to find that many were gone. Hurry out and look for it, there are few places that I often go to.

  At 6: 13 in the evening, she called the police.

  Jiang Zhongxiao saw that there was a difference of 7 minutes between a lot of time and the alarm time.

  Where can a 3-year-old child go in these 7 minutes?

  On the evening of March 27, the news of finding a 4-year-old girl lost in Qingshanhu Street in Lin ‘an was screened in the WeChat circle of friends. Qianjiang evening news APP "Zhejiang 24 Hours" also immediately pushed "4-year-old Lin ‘an girl lost for 6 hours, help turn! Contact Lin ‘an Public Security 61106110》&mdash clues & mdash; — Up to now, this news has been read nearly 450 thousand times.

  Many enthusiastic people rushed to pheasant dock village one after another, and the search team has rapidly increased from dozens to two or three hundred.

  "First, look inside and outside the village, empty houses, ditches beside houses, and other places where children may go." The relevant person in charge of the village Committee of pheasant dock village said that almost all the people in the village, men, women and children, participated, and the police of the local Qingshan police station did not sleep all night.

  Some people are worried about whether the child has suffered a more serious accident. Taking advantage of the night, several people searched separately, and some of them focused on ponds and reservoirs around the village.

  Zhou Yong, director of Qingshan Police Station of Lin ‘an District Public Security Bureau, stayed up all night, and his voice was extremely tired. "I received an alarm at 6: 13 pm on March 27. In fact, the worst plan was made at the beginning. " He said that the worst consequences that children may encounter include being trafficked and being violated.

  After receiving the alarm, the first wave of 15 policemen who searched quickly set off, and the video group also began to analyze and investigate the surveillance videos near the jurisdiction that day.

  At 7 o’clock that night, Zhou Yong reported to the District Public Security Bureau, and the community streets were linked at the same time, and the Criminal Investigation Brigade also rushed to the scene. At 8 o’clock in the evening, more than 40 police officers of Qingshan Police Station were all involved in the search (except the personnel on duty). At 10 o’clock in the evening, two emergency rescue teams in Lin ‘an and Fuyang rushed to the incident site with professional equipment. At 12 o’clock in the evening, search and rescue dogs joined the search team.

  According to the villagers, the total number of people on the scene at that time exceeded 300 (there were more than 1,000 participants before and after), and the carpet search was spread out.

  Get lost on the mountain with seven turns and eight bends

  She slept alone by the wild grave all night.

  Good news came early on March 28th! On the basis of a large number of investigations by the public security department, the emergency rescue commando team first discovered a lot.

  "At 8: 50 in the morning, I saw something moving 70 or 80 meters away. Looking closer, the little girl covered her head with clothes and was sleeping on the grass." The first child was Mr. Miao of Fuyang Xincheng Emergency Rescue Commando. He said that the child’s little feet that moved from time to time caught his attention.

  "I woke her up, and she didn’t cry, so she said she wanted to find her mother. It’s so happy, the child is safe and everything seems to be normal. "

  At noon on March 28, Qianbao reporter saw a lot. She pestered her mother for a hug and almost forgot what happened the night before.

  "Sleeping in one place, there are very big stones and very small bamboo, which can talk." She said to Qianbao reporter with her hand, with a naive face. She said she left by herself, and it got dark when she walked, and then she went to sleep.

  With the encouragement of my mother, I took everyone again — — She came out from home, walked a few meters, turned left on a road only 30 centimeters wide, turned right on a dirt road after 300 meters, and turned right again after 50 meters — — It’s hard to walk, there are puddles and mud, keep walking, walking, walking … …

  The 3-year-old Duo Duo has limited language skills and can’t describe the details accurately, but she still took us to a hillside — — It is about 1 km away from the village where Duoduo’s grandmother lives, and it takes nearly 30 minutes for adults to walk.

  "Look, isn’t there a big stone there? Just sleep here." The place with many fingers is a graveyard, and there are two shoes left by her in the haystack. "It’s so cold."

  "Yes, this pair of shoes is a lot." Mother Li Yue’s eyes are red again. Self-reproach, guilt, the night’s suffering and the luck that finally arrived made her unable to imagine her daughter’s night’s experience, and even more made her speechless.

  A lot of safe return made many people who participated in the search and rescue shed tears.

  Fortunately, the most worrying thing didn’t happen.

  As of press time, the police have not found any suspicious people or cars entering the village, nor have they found any evidence that the girl was controlled. She should have lost herself.
