Butterfly Change of Puhe Reservoir in Baoding, Hebei Province: A whole game of chess with clear water in one reservoir.

    In September, the "green gauze tent" filled the vast central Hebei plain, and the waterfall river in Xushui District of Baoding City, Hebei Province shuttled through it like a blue belt, flowing silently at the foot of Taihang Mountain, and meandering eastward into the algae pond on the westernmost side of Baiyangdian Lake.

    Overlooking the waterfall river, the water plants are swaying and the fish are shuttling. The breeze started at first, and the small waves jumped, which inadvertently alarmed a group of egrets foraging in the shallows. They flew up and then fell.

    Overlooking the mountains, the trees are lush and green, and the lakes and mountains are staggered and picturesque.

   Puhe Reservoir "Rebirth" with Water to Continue Homesickness

    Puhe Reservoir, located in Puhe Township, Xushui District, is the main stream reservoir of Puhe River, which was founded in 1958. Among the Eight Scenes of Xu Shui recorded in xushui county Xinzhi, there are three waterfalls, namely "Qingxi printing the moon", "watching fish on the bank" and "Changhong sunset". In 1980s, the reservoir area collapsed one after another, and the reservoir water decreased sharply every year. By 2008, the Puhe Reservoir had been exhausted. The beauty of water and grass is no longer there.

    Because of its remote location, harsh environment and backward infrastructure, the economy of the villages around Puhe Reservoir was once backward. "Young and middle-aged people go out to work, and most of the rest in the village are old people and women, with traditional agricultural cultivation as the main source of income." Mi Shiliang, secretary of the Party Committee of Puhe Township, said that the "presence" of Puhe Township in Xushui District at that time was very low.

Puhe Reservoir

    The ecological change of Puhe Reservoir began in 2018.

    Baoding, located in the hinterland of Beijing, Tianjin and xiong’an new area, is an important ecological barrier for Beijing, Tianjin and. In order to serve the construction of the new district, Baoding has launched an ecological defense war for Baiyangdian in an all-round way since 2018, and comprehensively implemented various comprehensive measures such as sewage treatment upgrading, rain and sewage diversion transformation, river ecological dredging, constructed wetland construction, abandoned mine restoration and treatment, and ecological water replenishment to promote the comprehensive management of the upper reaches of Baiyangdian. This has also revived the waterfall reservoir area that has been abandoned for more than 20 years.

    "The waterfall reservoir is connected to the main canal of the middle route of the South-to-North Water Transfer Project and connected to the waterfall river channel. Since 2018, the reservoir has been diverting clean water from the South-to-North Water Transfer Project to replenish water for Baiyangdian." Li Liu, director of the office of Xushui District Water Conservancy Bureau, said that in 2020, the waterfall river was identified as the normalized recharge channel of Baiyangdian Lake, and since April 2018, the cumulative ecological recharge to Baiyangdian Lake has reached 450 million cubic meters.

    "On the day of water release, the reservoir was surrounded by people." Xi Xiaoxian, a villager in Jiecun Village, Puhe Township, still remembers the scene of water coming from the reservoir area. In her view, the water attracted not only filled the waterfall river, but also continued the homesickness of the villagers.

   Pollution control and greening, rare birds "in the same box"

    In order to "prevent a drop of sewage from flowing into Baiyangdian Lake", the Xu Shui Municipal Party Committee and District Government has been steadfast in tackling tough battles such as pollution control, ecological restoration and greening corridors.

    "The stable effluent of sewage treatment plants can meet the third-class water standard, which can be used for farmland irrigation and livestock drinking." According to Liu Jianjun, general manager of Xu Shui Sewage Treatment Plant, the effluent standards of all sewage treatment plants in Xushui District have reached the discharge standard of Daqing River core area, and the daily sewage treatment capacity is 30,000 cubic meters.

    Li Liu said that from 2017, the district will comprehensively establish a three-level river patrol management system at district, township and village levels, actively carry out the special action of "cleaning up the four chaos" in rivers, improve the full-time management team of reservoirs, carry out joint law enforcement of water conservancy, public security, environmental protection and neighboring township governments, and promptly investigate and deal with acts that endanger the safety of reservoirs and destroy the ecological environment.

    In addition, in recent five years, Xushui District has completed 80,900 mu of afforestation, focusing on the construction of high-speed high-speed rail corridor and 500-meter forest belt around xiong’an new area, and built a green ecological barrier in the upper reaches of Baiyangdian Lake. The ecology of the waterfall river is gradually improving.

    Wild birds are an ecological barometer. In recent years, more and more wild animals around the waterfall river have come from generation to generation.

    "In 2019, the waterfall reservoir attracted swans. In 2020, crested pheasants, kestrels, mallard ducks and spoonbills began to gather here; In 2021, a large number of geese migrated; In 2022, the national first-class protected animal Great Bustard appeared … "Shi Jianfang is a bird photographer. From the autumn of 2018 to the summer of 2022, more than 80 species of birds were photographed in the waterfall river, including more than 10 species of national first-class and second-class protected animals. He witnessed the increasing number of birds in the camera.

   The mountains and rivers are treated together, and the barren hills are "covered with green and golden"

    Landscape ecology is an organic whole, and there is a folk saying: "Planting trees on the mountain is equivalent to building a reservoir."

    Shilongshan is located in the northwest of Xushui District, separated from the Puhe Reservoir by a dike. Due to the disorderly mining in the early years, the mountain was broken and the vegetation coverage rate was less than 10%. Since 2011, Xushui District has started the ecological restoration of Shilongshan through government-enterprise linkage.

    "We have invested more than 3 billion yuan, and it took more than 10 years to raise this riddled mine from the original 10% greening rate to the current 80%." According to Shi Jianguo, the person in charge of ecological restoration in Shilongshan, the project specially hired a team of experts from Chongqing to issue a mountain restoration plan, which greatly reduced the risk of geological disasters such as landslides, mudslides and dangerous rock collapses by cutting slopes and reducing loads, lattice slope protection and anti-slide piles, and fully combined with the trend of mountain topography, selected suitable vegetation types and reshaped the ecological environment.

    After 10 years of mountain management, the "scar" faded, and the barren hills were covered with green, quietly painting an ecological picture of green mountains surrounded by water and green waters.

    Nowadays, Shilongshan has not only become the ecological barrier of the waterfall river, but also become a leisure and holiday resort with the 8,000-mu waterfall river reservoir, including agricultural formats such as land grain painting and vegetable art garden, recreational formats such as caravan camps, unpowered parks and homestays, as well as labor and practical education bases for primary and secondary school students.

   Ecological resources become rich capital, and the integration of agriculture and tourism unlocks rural revitalization.

    The waterfall river ecosystem has gradually formed, and the local government has begun to introduce social capital and high-quality projects to explore green growth points and promote the integration of agriculture and tourism.

    On the south bank of the reservoir area, Baoding Haojing Tourism Development Co., Ltd. relies on the good ecology of Shilong Mountain and waterfall river to vigorously develop agricultural industrial clusters and develop green ecological products with local characteristics, such as Moushan dry valley, Busan millet and waterfall river sunflower oil crops. At the same time, the company actively cooperates with Hebei Agricultural University, a number of leading agricultural enterprises, livestock breeding enterprises, agricultural planting bases and family farms in various forms to promote the integrated development of agriculture and tourism.

    Industrial linkage development, stretching and improving related industrial chains, creating more business opportunities for local people and enhancing the economic value of the whole region.

    Mi Shiliang said that driven by leading enterprises, the employment problem of a large number of villagers around has been solved. With the increase of tourists, the villagers’ willingness to develop homestays and farmhouses has gradually increased. What makes Mi Shiliang more gratified is that he has recently received frequent consultation calls from investors. From the "small transparency" of "nobody cares", the waterfall river township has now become the "fragrant cake" in the eyes of everyone.

   The flourishing of landscape green culture leads to new kinetic energy for development.

    "The waterfall river with a long history is not only the old course of the Yellow River, but also known as Yishui in ancient times and belongs to Nanyishui. There are many cultural allusions and sites here. " According to Mi Shiliang, there are Yangshao Cultural Site, Busan Site of Huangdi Hefu, Chiyou Solitary Tomb of Hongtu Mountain and Yannan Great Wall Site around the Waterfall River.

    With the rejuvenation of the waterfall river, the waterfall river culture has once again entered the public eye. In December, 2021, Yannan Great Wall Site was selected into the list of "One Hundred Important Archaeological Discoveries in Hebei in a Hundred Years", which attracted a large number of cultural relics workers, historical and cultural enthusiasts and tourists to "punch in".

    The ecological restoration of the waterfall river has activated the historical context. On the other hand, the prosperity of culture has also injected new development momentum into the waterfall river. On September 8th, the Waterfall River Ecological Leisure Resort made a stunning appearance at the 5th Cultural and Tourism Industry Development Conference in Baoding, opening a new historical chapter.

    One son falls and is full of vitality. The ecological restoration of the waterfall river has revitalized the local agriculture and culture, created a "waterfall river ecological leisure resort" with rich landscape and rhyme, and promoted the integration and development of the "agricultural tourism" industry. The green mountains and green hills are changing to "Jinshan Yinshan".

Bali shopping guide

  The most worthwhile things to buy in Bali are local handicrafts, such as wood carving, stone carving and batik. If your wallet allows, you can also buy some works by local artists.

  In Kuta, Denpasar, Nu Shadoa and other places, the price will be more expensive because of the large number of tourists. There are many villages in Bali that specialize in producing certain handicrafts, such as Mas and Sulu. Buying them in workshops is not only cheap, but also can witness the whole process of making these exquisite instruments. Ubud in Bali is the best place, and many handicrafts sold by shops in Kuta and other places are wholesale from here.

  Special note:

  1. You should bring enough cash to buy things in Bali. Most small shops with cheap prices do not accept credit cards, while the prices in large handicraft shops and duty-free shops are much more expensive.

  2. Be careful that there are some artists near the tourist attractions who ask tourists for high prices and sell fake antiques.

The latest progress has been made in the death case of the first "Tesla autopilot" car accident in China.

  CCTV News:Recently, the first fatal case of "Tesla Autopilot" car accident in China, the case of Tesla owner Gao Jubin, the father of the vehicle driver Gao Yanning who died in the accident, sued Tesla China Company, which made the latest progress after more than a year of difficult trial. Tesla finally confirmed that the vehicle was in an "automatic driving" state when the car accident occurred. This is only a small progress in this case, and the process of litigation still has a long way to go. So, what kind of traffic accident is this?

  On January 20, 2016, a serious rear-end collision occurred in Handan section of Beijing-Hong Kong-Macao Expressway in Hebei Province. While driving in the first lane on the left, a white Tesla car ran into a road sweeper that was working ahead.

  There were no brake marks before the collision.

  In the process of handling the accident, the high-speed traffic police did not find any brake marks on Tesla cars before the collision. Combined with the on-site investigation and video data of driving recorder, after careful investigation, the high-speed traffic police department issued a letter of responsibility for this traffic accident.

  Jia Weichuan, Director of Cixian Brigade Office of Hebei High-speed Traffic Police Handan Detachment: "The driver of the white Tuosule (Tesla) car did not take braking and avoidance measures when encountering the vehicle in front, which should be the main cause of the accident."

  After being sent to two hospitals for emergency treatment, Gao Ya Ning, who was driving a Tesla sedan at that time, eventually died of his injuries and lost his 23-year-old life.

  Gao jubin: "I always feel that the child died a little unjustly, and I have to find out the reason."

  Analyze the driving video and infer it as "automatic driving"

  Gao Jubin thought of the "automatic driving" function that his son had mentioned many times. After many experts were invited to study the video of the driving recorder, everyone unanimously speculated that it was precisely because Gaoyaning started the "automatic driving" function during driving and handed over the driving to the vehicle, and the "automatic driving" system failed to identify the vehicle in front, which eventually led to tragedy. Therefore, in July 2016, Gao Jubin sued Tesla’s sales company in China to the Chaoyang District People’s Court. Claim compensation for the loss of 10 thousand yuan.

  Gao Jubin’s attorney, Wang Beibei.: "In fact, the amount of this compensation is not the purpose pursued by this case. We hope that through this case, it will have some social value and let the public know this ‘ Autopilot ’ The technology is flawed. Because of this immature technology, once you cause a vicious accident, it is a broken family like Mr. Gao. "

  Both the defendant and the original witness to take out the data memory card.

  On October 18, 2017, Gao Jubin finally waited for the day to test this Tesla car. After the accident insurance claims ended, Gao Jubin bought back the wreckage of this car from the insurance company and kept it in the garage. Now, the data stored in the car has become the most important basis for finding the truth of the accident for my son.

  The plaintiff’s attorney, Guo Qing.When the garage door rose slowly, I stood at a distance of about two meters from the car. I saw that the car was exposed bit by bit, and it had crashed into powder, like a ferocious monster, and my heart was shocked.

  Under the auspices of the judge and witnessed by both the original defendant and the defendant, the staff of Beijing CIMC Vehicle Judicial Appraisal Center inspected the vehicle. After more than a day, the appraisal agency completed the inspection of the vehicle and took out the memory card with the data of the vehicle driving state from the vehicle.

  Get the data of memory card and send it to America.

  After taking out this memory card, at the suggestion of the plaintiff’s attorney, both the original defendant and the defendant found a professional institution recognized by both parties and made a mirror copy of the contents of the memory card. The original defendant and the court each keep one copy. At this time, it is already January 2018, and it has been two years since the traffic accident occurred. After that, the data will be transmitted to the United States.

  On February 26, 2018, the first Monday after the Spring Festival, several people came to the Tesla delivery center again and sent the data in the memory card back to the United States. The process of uploading is very simple. The judges put seals on the computers used for uploading and the doors and windows of the office where the computers are located to prevent people from entering. There are also surveillance cameras on the roof of the corridor.

  Gao jubin’s wife Gao juhong: "At night, we still don’t feel at ease. The two of us are downstairs. Several of us took turns staring at it all night. Now I am afraid that even if there is a little hope, I want to have an explanation for my child, for fear that there are some loopholes and I am sorry for my child."

  Interpretation of stored data was "automatic driving" at that time.

  At two o’clock the next afternoon, the judge of Chaoyang court, the staff of the Judicial Appraisal Center of China National Aircraft Corporation and the original defendant came to this office again to check the return results. In response to the returned data results, Tesla engineers cooperated with the interpretation on the spot.

  Gao jubin: "In the later period, at 2: 07 after repeated questioning, until the crash, what was the explanation of this letter? Finally, after repeated questioning, they told me that this was automatic driving, which finally proved that their son used automatic driving. There is also a data reading behind, and my son’s feet are still stepping on the brakes. I think it should be in the collision. When it is about to collide, it is estimated that the child found it, as if he wanted to brake with his feet. "

  Gao Jubin told reporters that in April 2017, he had proposed to the court to adjust the amount of the claim from the original 10,000 yuan to 5 million yuan in response to Tesla’s prevarication and procrastination attitude in the previous litigation. At present, Gao Jubin’s lawsuit is still going on, and Tesla’s "automatic assisted driving" system is constantly updating and iterating.

  Expert: There are five levels of autonomous driving technology.

  According to Professor Yang Diange, director of the Department of Automotive Engineering in Tsinghua University, at present, the auto-driving technology of automobiles is mainly divided into five levels.

  Yang Diange, Director of Automotive Engineering Department of Tsinghua University.: "The first-level and second-level autopilot can be regarded as a low-level autopilot, which is commonly known as the driver assistance system. At the third level, it is actually a man-machine co-driving, and at the fourth level, it is called conditional high-level autopilot. At the fifth level, it is completely unmanned."

  According to Director Yang Diange, Tesla’s system should be at the level between the second and third levels.

  Yang Diange, Director of Automotive Engineering Department of Tsinghua University.: "It should not be regarded as a very advanced automatic driving system. So from a technical point of view, it may be more appropriate to call it a driver assistance system. "

  Car companies should have social responsibility to ensure safe use.

  Director Yang Diange said that this requires automobile manufacturers to have a high sense of social responsibility.

  Yang Diange, Director of Automotive Engineering Department of Tsinghua University."Automobile products are completely different from mobile phone products and computer products. It involves human life safety, and the requirements for its reliability are very high. Therefore, it is also very important to make great efforts, spend a lot of investment and do long-term tests in technology to ensure its safety, and at the same time let the people better understand, understand and use these technologies."

Is it possible for people to spit out shit when they vomit? The doctor said: Yes.

Original: medical rivers and lakes of DrX, medical rivers and lakes of DrX

The full text is 1879 words, and it takes 5 minutes to read.

◆ ◆ ◆ ◆ ◆

If you are eating or preparing to eat, the following content may not be very friendly to you.

Shit, as an important part of maintaining human physiological operation and life activities, is self-evident. Whether you like it or not, we must face this fact from the moment we are born.

Shit can be said to be one of the most important life activities in a person’s life. It will make you feel comfortable all over, forget all your troubles, and let you sit on the toilet and pour a thousand miles, and live a rainy life with the red dust of the toilet from now on.

Just today, Dr.X saw such a question on the Zhihu:

"When people vomit, is it possible to spit out shit? 」

In an instant, "a life of shit" began to emerge in my mind. With the sensitivity of a medical worker, Dr.X must popularize "Will shit be vomited?" 」

Yes!

Why? There are many reasons, the most important of which is intestinal obstruction.

The following content comes from the personal experience of an oncology intern:

An old man with low intestinal obstruction came to the department. He didn’t defecate for about ten days and had severe abdominal distension.

After coming to the department, the first thing to do is to insert a gastric tube for drainage. When the patient opened his mouth, a pungent and strong smell of feces came to his face.

The patient vomited just after the drainage tube was fixed and it didn’t work.

In an instant, the patient’s clothes and sheets were covered with thick liquid fecal vomit. Followed by the second and third waves of shocks … the families of patients standing on the side are stupid.

Imagine that all kinds of digestive juices and foods have been fermented in the human body for more than ten days. What kind of "wonderful" taste is this?

Is it possible to spit out shit?

I’m afraid this smell is worse than shit and more disgusting than shit.

Of course, no one wants this to happen to himself, but since the disease of intestinal obstruction has been developed, no matter how disgusting it is, it has to suffer.

In addition to nausea and pain, we can’t ignore the danger of long-term inability to defecate.

There is a disease called congenital colon, because the congenital colon development is abnormal, which leads to some large intestine or the whole large intestine in a state of spasm, and it is difficult to pass stool.

The young man in the picture below suffers from Hirschsprung’s disease. When he was 16 years old, he could only defecate once a month, so that his stomach became bigger and bigger.

Finally, at the age of 29, the man was found dead in the toilet while he was trying to defecate. After dissecting his body, it was found that his colon was many times larger than that of ordinary people, and the thickest part had reached a diameter of 76cm, while the stool inside was a full 18 kg.

The picture below is a specimen made of his colon, which is now on display in a museum in the United States.

Hirschsprung’s disease (HD) is a deformity characterized by the lack of nerve cells in the intestinal wall. Generally, the ganglion-free segment of the colon is located at the distal end of the colon, and the intestine of the ganglion-free segment lacks propulsive peristalsis. At this time, the intestine is in a spastic state, which will cause colon obstruction.

Generally, children with HD will have related symptoms within 24-48 hours after birth. If the baby has abdominal distension, delayed meconium discharge or even vomiting after birth, it is necessary to check whether it is Hirschsprung’s disease in time. In addition, 50%-90% of children will have abdominal distension, bile vomiting, intractable constipation, etc., and 10% of children will have fever, abdominal distension, diarrhea, and recurrent attacks, and even fatal risks.

Therefore, Hirschsprung’s disease cannot be ignored.

Congenital colon of the man above is relatively rare, and intestinal obstruction is more common. In medical terms, intestinal obstruction means that part or all of the intestinal contents cannot flow normally or pass through the intestine smoothly.

Generally, nearly 90% of intestinal obstruction will occur in the small intestine, especially in the narrowest ileum, and colon obstruction is more likely to occur in the sigmoid colon.

The condition of intestinal obstruction is very changeable. Don’t think it’s just simple constipation or indigestion. In many cases, carelessness may be life-threatening. According to the data of the World Health Organization, the mortality rate of small intestinal obstruction in the United States is 10%, and the mortality rate of colon obstruction is even higher than 30%.

If diagnosis and treatment are not carried out within 24 hours, the mortality rate will continue to increase.

Why do you still suffer from intestinal obstruction when you clearly pay attention to healthy diet and often exercise?

Before that, you need to recognize the cause of intestinal obstruction.

In fact, there are many reasons that can cause intestinal obstruction. Generally, the causes of intestinal obstruction may be inflammation, tumor, adhesion, volvulus, intussusception, food mass blockage and even intestinal stenosis caused by external pressure. Of course, serious infection can also cause intestinal obstruction. It is worth noting that more than 80% of mechanical intestinal obstruction in large intestine is caused by tumor, which is most likely to occur in sigmoid colon.

Because the tumor grows slowly and the intestinal cavity of the large intestine is relatively wide, it is usually blocked by fecal blocks in the obstructed area and induces or aggravates the condition of intestinal obstruction. In general, the manifestations of small intestinal obstruction are often the first symptoms of small intestinal tumors, and the lumen of the small intestine may be a little narrow, but there are many substances in the small intestine and they are generally fluids, so the obstruction will not appear in the early stage of tumor occurrence. This means that when the obstruction occurs in the small intestine, the small intestine tumor may have been there for some time.

It should be noted that malignant intestinal obstruction (MBO) is generally the most common complication of patients with advanced tumors, usually intestinal obstruction caused by primary or metastatic malignant tumors, which accounts for 5%-43%. The primary tumors of general intestinal obstruction are ovarian cancer (5.5%-51%), colorectal cancer (10%-28%) and gastric cancer (30%-40%)

Seeing this, do you dare to ignore your defecation problem? In particular, the problem of intestinal obstruction in middle-aged and elderly people needs special attention. Dr.X has contacted many patients with intestinal obstruction, and most of them think that they just have poor defecation, but in the end they have detected various tumors, most of which are intestinal cancer.

We won’t elaborate so much on the causes of intestinal obstruction, after all, it is hard for ordinary people to understand. Let’s focus on the manifestations of intestinal obstruction, and readers in front of the screen can also judge whether they have signs of intestinal obstruction according to their own situation.

abdominalgia

Abdominal pain here is generally paroxysmal severe colic, which generally has the following characteristics:

Wave-like pain from light to heavy and then relieved;

When you have an attack, you can feel a sharp drop in gas, and it will suddenly stop when you reach a certain part of the body. At this time, abdominal pain is generally the most intense;

When abdominal pain occurs, you can feel that the intestinal type is moving.

Stop defecation

This is the most typical feature of intestinal obstruction. However, when suffering from high intestinal obstruction, there will be a small amount of defecation and gas discharge in the early stage, which will cause many patients to be paralyzed. Strangulated intestinal obstruction can discharge bloody mucus-like stool.

vomit

Vomiting usually comes with intestinal obstruction at the same time, which is generally reflective in the early stage. At this time, the vomit is food and gastric juice, and the vomit in the above case is still relatively rare. When intestinal obstruction enters the quiescent stage, vomiting will be more frequent at this time, and the vomit at this time is gastric juice, duodenal juice and bile.

After the rest period, vomit is an object with the smell of feces, which is commonly known as "shit".

abdominal distention

This situation usually occurs after the obstruction has occurred for a period of time. The degree of abdominal distension here is largely related to the obstruction site, and abdominal distension is not obvious when suffering from high intestinal obstruction. But when suffering from low obstruction, the whole abdomen will swell.

It is worth noting that strangulated intestinal obstruction is likely to bring serious consequences, so once you have the following symptoms, don’t hesitate to seek medical attention!

Sudden abdominal pain with persistent severe pain

Vomiting occurs early, violently and frequently.

As the body temperature rises, the pulse rate increases.

Abdominal distension is asymmetrical, and there is obvious local bulge in the abdomen.

Vomit or excrement contains bloody liquid.

Dr.X said

Intestinal health is not only related to the digestive system, but also affects the intestinal flora and the cognitive development of the brain. If you feel stupid, it may be the intestinal cause ~

Finally, if you find yourself with chronic constipation, diarrhea, or even intestinal obstruction, please seek medical advice as soon as possible to avoid irreparable consequences.

In the first three quarters, the installed capacity of renewable energy increased by 90.36 million kilowatts.

  Science and Technology Daily, Beijing, November 14th (Reporter Liu Yuanyuan) On the 14th, the National Energy Administration held an online news conference for the fourth quarter to introduce the energy situation in the first three quarters of 2022 and the grid-connected operation of renewable energy.

  "In the first three quarters of 2022, China’s renewable energy installed capacity was 90.36 million kilowatts, accounting for 78.8% of the country’s new power generation installed capacity." Wang Dapeng, deputy director of the New Energy and Renewable Energy Department of the National Energy Administration, said that the installed capacity of renewable energy has steadily expanded. Among them, hydropower increased by 15.9 million kilowatts, wind power increased by 19.24 million kilowatts, photovoltaic power generation increased by 52.6 million kilowatts, and biomass power generation increased by 2.62 million kilowatts, accounting for 13.9%, 16.8%, 45.8% and 2.3% of the newly installed capacity in China respectively.

  By the end of September 2022, the installed capacity of renewable energy power generation in China reached 1.146 billion kilowatts. Among them, hydropower installed capacity is 406 million kilowatts (including pumped storage capacity of 43 million kilowatts), wind power installed capacity is 348 million kilowatts, photovoltaic power generation installed capacity is 358 million kilowatts, and biomass power generation installed capacity is 40.6 million kilowatts. The power generation of renewable energy has also increased steadily: in the first three quarters of 2022, the national renewable energy power generation reached 1.94 trillion kWh.

  "Renewable energy continues to maintain a high level of utilization." Wang Dapeng said that in the first three quarters of 2022, the water energy utilization rate of major river basins in China was about 98.6%, an increase of 1.1 percentage points over the same period of last year; The average utilization rate of wind power in China is 96.5%, which is 0.5 percentage points lower than the same period of last year. The average utilization rate of photovoltaic power generation in China was 98.2%, an increase of 0.2 percentage points over the same period of last year.

  Dong Wancheng, deputy director of the Development Planning Department of the National Energy Administration, said that the first batch of large-scale wind power photovoltaic bases have all started, and the second batch of projects are starting one after another. At present, the third batch of project review is being promoted. In the first eight months of this year, the investment in key projects in the national energy field was 1,229.5 billion yuan, up 16.7% year-on-year, 0.8 percentage points higher than the growth rate in the first half of this year.

  "Anchoring peak carbon dioxide emissions’s carbon neutrality, ‘ Fourteenth Five-Year Plan ’ During this period, we will thoroughly implement ‘ Four revolutions and one cooperation ’ The new strategy of energy security promotes the high-quality leap development of renewable energy. " Wang Dapeng said that in terms of production, the development mode will be optimized and renewable energy will be developed on a large scale; In terms of technology, we will adhere to the drive of innovation and develop renewable energy with high quality. Intensify the research on renewable energy technology innovation, fill in the shortcomings of technology and equipment, accelerate the cultivation of new models and formats, improve the modernization level of industrial chain, enhance the flexibility and toughness of supply chain, and continuously consolidate and enhance the international competitiveness of China’s renewable energy industry.

Guide to the design of humanoid robots

This article comes from WeChat WeChat official account:Cody products go to sea (id: chenfeng element), Author: Chen Feng, original title: "Humanoid Robot Design Guide: How to find a way out for consumers?" 》, the title picture comes from: TESLA

Musk’s product design once again swept our field of vision, this time it was a humanoid robot.

Tesla Optimus Prime Product Design Path

On September 30th, Optimus Prime, which aims to "reshape the future of the labor force", was released, adding more variables to the product design of humanoid robots.

On August 11th, before Tesla, Xiaomi released his own humanoid robot CyberOne, code-named "Tieda". A well-known domestic artificial intelligence solution provider, Ubisoft, also released a new generation of Walker X in October last year.

The isometric drawings of Optimus Prime and other large-scale product designs.

However, if the DEMO released this time is shown to the Japanese fifty years ago, I’m afraid the product designers will be disappointed. As early as 1972, Waseda University in Japan had made the first full-size humanoid robot WABOT, which could communicate in Japanese, navigate indoors and grab objects.

Wabot is highly similar to the DEMO of Optimus Prime.

Fifty years later, humanoid robots seem to be stuck in the castle in the air of cutting-edge technology, and it is difficult to get out of the laboratory and land. Aside from Tesla’s brand aura, where does the future design of humanoid robots lead?

Chronicle of Honda ASIMO product design

From psychology to art, from product application to steering gear cost, humanoid robot may be the most challenging product design in human history.

Challenge uncanny valley.

In the classic book Crossing the Gap, Geoffrey Moore thinks: "The most dangerous and crucial point in the process of high-tech products coming out is the transition from the early market dominated by a few visionaries to the mainstream market occupied by a large number of customers dominated by pragmatists."

Tesla CyberTruck’s sense of the future is inseparable from industrial design.

Compared with Tesla’s previous CyberTruck and Model electric cars, humanoid robots rely more on industrial design. Only in this way can we achieve a thrilling leap from laboratory prototype to commercialization.

The theory of horror valley belongs to the industrial design of humanoid robots. If humanoid robots try to approach real people from various characteristics, users’ expectations for design will be unattainable.

"uncanny valley" Psychological Theory in Robot Design

Once designers pay too much attention to appearance and emotional expression, such as trying to recreate human muscles and skin, they will easily fall into uncanny valley, and become a failed commodity like the "corpses" of countless laboratory DEMO lying at the bottom of the valley.

The list of "scary robots" on IEEE

Zhang Haochong, director of Naiyang Creative Design, said: No matter from the design trend or the current product technology, the more effective design ideas are not to challenge the "uncanny valley", to resist the impulse of design, and to design robots as "digital products" and "home appliances" to avoid the corresponding seats for real people.

This means that on the left side of uncanny valley, there is still a vast design space to prove the consumption value.

How many obstacles are there to overcome in designing the dream humanoid robot commodity?

Overcoming Moravik Paradox

In fact, the design of humanoid robots has never been seen by the AI industry.

In 2012, teacher Kai-fu Lee once commented that the idea that humanoid robots will enter thousands of households immediately is simply nonsense.

Peter teale, the founder of Paypal, came to the same conclusion: "It’s just a simple action to let the robot take out the dirty clothes from the basket and put them into the washing machine". In the opinion of the engineers he communicated with, "it can’t be seen in his lifetime."

The criticism of AI predecessors is not groundless. Its foundation is actually one: Moravik paradox.

Humanoid robots are smart, but their movement ability can never keep up with the algorithm.-Because the existing motors and sensors are not accurate enough, the limbs are extremely underdeveloped. It can copy the story of AlphaGo countless times, easily defeating humans in data calculation and quiz, but it can’t twist a door handle and pick up a water cup accurately-not as good as a three-year-old child.

All children’s sports skills: picking up pencils, running and jumping, and tightening bottle caps-all are the most difficult problems for humanoid robots so far. A cold joke in the AI industry is that manual jobs such as gardeners, receptionists and chefs don’t have to worry about being replaced within 30 years.

The limitation of Moravik’s paradox is what all robot designers need to face up to.

The daunting design cost.

The industrial design of humanoid robot needs abundant funds to irrigate it.

The joints of Tesla Optimus Prime contain a large number of motors.

To create a perfect robot design, ABS plastic shell and color matching are only small heads among small heads, and a large number of joints and servo steering gears are needed to support the design.

Exploded view of millet CyberOne hip motor structure

Relevant practitioners have revealed that the cost of servo steering gear system accounts for 40% to 50% of sports robots. The multi-stage steering gear needed to realize human action design and the high price of accessories force humanoid robots to bid farewell to high quality and low price at the consumer end.

The common servo steering gear on Taobao is expensive.

Tesla shouted out a customer unit price of $20,000 at the press conference, but this is still not an acceptable price for the consumer market.Even in the field of children, considering the lower customer unit price of toy robots, the high cost of motors will not change because of their size, which greatly reduces the cost space.

Small steering gear for children’s toys is also expensive.

For Tesla and any robot, the whole body needs countless steering gears to drive, and the cost fluctuation of any motor is a factor that cannot be ignored when designing products.

Home furnishing field

If you want to design humanoid robots for the home field, the first thing to consider is the material and color matching.

White material is a common color for household appliances in industrial design. It has also become the home color matching standard for humanoid robots.

However, the curse of Moravic’s paradox is the strongest in the field of home.

Although the humanoid home robot has always been a design that attracts people’s attention, it has always been far from the designer’s expectations: since its inception, humanoid robots have been subjected to various "less human-like" home robots.

From 2021 to 2022, Aqara Green Rice and Eurobo completed financing with a total amount of 1 billion yuan respectively. It has become the two largest financing for smart homes in recent years. Humanoid robot and smart home are both capital-intensive industries, but the former is a research and development need, and the profit is far away; The installed capacity of the latter products is well documented.

Aqara’s various professional home robot matrices

In Japan, where ASIMO home robot was born, there is a unique SwitchBot company.

Its product design style is to use a small motor to quickly control the common buttons and door handles at home. To achieve the same function, humanoid robot needs the identification, positioning and linkage of dozens of servo motors.

The humanoid robot needs dozens of steering gears to twist the door handle.

A large number of micro-powered robots directly skipped the defense line of Moravik paradox. When humanoid robots are still studying how to form a mechanical arm with a variety of steering gears, press the switch and unlock the door lock with high precision, the IoT robot chose to reduce the dimension.

The best-selling button robot in Hong Kong, Macao and Taiwan and Japan.

This is a moment that has appeared many times in the history of industrial design: in the 19th century, Germans once carved guns with the same high quality as works of art, which is still a model of design collection; The British designed a cheap, simple gun which is suitable for rapid and large-scale industrial manufacturing. When low-cost small steering gear can quickly realize the home scene of dozens of heavy steering gear linkage, the balance of war will inevitably tilt to the other side of the humanoid vase.

The search volume of Google Trend, a home robot, is significantly higher than that of humanoid robots after 2011.

What few people know is that before Tesla and Xiaomi’s robots, the once-popular Honda ASIMO home robot officially retired in March 2022.

On March 31st, 2022, Honda ASIMO robot officially retired.

The performance of humanoid robots on the home stage has ended before it started.

Although this expression is somewhat cruel, it is hard not to think that the design behind Tesla’s "Optimus Prime" and Xiaomi’s CyberOne today is just a replica of the defeated soldiers in the home battlefield.

An educational scene that is beyond one’s power

Outside the smart home stage, humanoid robots could have found another way to capture children’s desks as "educational robots".

The design opportunity began in 2017, when the State Council issued the artificial intelligence education policy.

This policy has greatly stimulated the demand for robot education. In front of major companies, it is a grand blue ocean market. In 2018, Ubisoft hired Takahashi Zhilong, who had designed RoBohon robot, as the chief product officer to take charge of product design.

China and Japanese robot industry designers met on the education track.

Everything about the humanoid educational robot looks beautiful.

Take the "Wukong" released in 2019 as an example. The size of the mini makes it not be regarded as a real person, avoiding the pit of the horror valley effect; As the most acceptable interactive carrier for children, humanoid can play the role of children’s learning companion and promote students’ social skills of communicating with others, understanding emotions and expressing. You can also get through all kinds of educational IP and become a traffic portal.

However, there have been professional teachers’ voices opposing humanoid design.

The reason is the familiar Moravik paradox: the educational subjects of humanoid robots are mainly mathematics, physics and engineering project learning, and the reasonable and efficient educational product modeling is actually not bound by humanoid.

The best-selling robots in Amazon, USA, are usually wheeled or tracked.

A robot product designer before making a child’s heart gave an example of an excavator: assuming that the mechanical arm and the principle of the mechanical arm should be taught in the primary school curriculum, the product form should reflect the semantics of mining. In modern classroom teaching, when introducing the popular science of robots, children’s reaction after getting humanoid robots is bound to exceed expectations: "Can it help me move things?" "Can these two robots race?"

Motionblock modular robot is a typical idea of split design according to projects.

Among them, the ability to walk and exercise is far beyond the ceiling that humanoid robots can meet from the beginning.

Teacher Cheng, who has used Alpha and Wukong robots to write courses, said: "Humanoid robots are very cost-effective and can’t support a few classes." Ye Yonghao, chairman of Yuzhi Kechuang, revealed: "Humanoid robots usually have requirements for venues and teachers, and institutions will not use human figures. Primary and secondary schools rarely introduce it. Even if there is, it is also the display purpose led by the Education Bureau. "

Modular educational robot occupying the market

The consensus reached by the education sector not only that teaching should not be restricted by human design, but also includes the need for emotional expression.

In April 2001, in Los Angeles, a studio named Cozmo Robot was established. Its products will be praised by many robot teachers, designers and even small bosses of Dongguan toy factory, and will occupy a very heavy weight in the design history of robots and educational toys.

Vector is not a humanoid design, but the introduction of LED panel brings emotional design to the extreme.

What makes Cozmo famous is the extremely rich emotional design. "This is what robots should look like. Please stop making humanoid robots like nightmares!" Become a representative of the consumer market.

High praise product reviews under the evaluation of Unbox Therapy

Cozmo’s design idea reduces the market’s dependence on human form and turns to richer expression design to meet the better output of children’s content. Drive the head expression of humanoid robot to develop in a rich and delicate direction.

The subsequent development has nothing to do with human form:After 2020, with the outbreak of online education and the decrease of the cost of superimposed screen components, the design trend is to further enlarge the expression panel and cut off the expensive humanoid joints.The industrial design at this stage is essentially a tablet computer dragging its body and speakers.

Image source: finishing by the author

Zhang Haochong, who has participated in Corbit, mTiny and Codey Rocky, pointed out the reasons:No matter the cost of steering gear, the feasibility of technology or the actual cost, its content can not bear the main responsibility of humanoid robot as education.

From school to family, from desks to dining tables, a large number of modular and kit toys and teaching AIDS have occupied the fields that Takahashi Zhilong and humanoid robots once dreamed of. However, due to the lack of support from professional B-end users, the proportion of humanoid modeling in the educational product line will inevitably decline.

Commercial performances and reception scenes

Tesla "Optimus Prime" pays attention to different physical labor scenes, and the commercial exhibition and reception in Chinese mainland is the undisputed home of humanoid robots.

The annual Spring Festival Gala is a battleground for all kinds of traffic operations for China Internet companies; For humanoid robots, it is a window to show product design.

In 2016, 540 Alpha humanoid robots landed in the Spring Festival Evening of the Year of the Monkey, and completed the product appearance in the song of Sun Nan’s "Rushing to the Peak"; Three years later, six Walker robots landed at the Shenzhen Branch of the Spring Festival Evening again. Subsequently, Ubisoft received a $100 million investment from CDH and CITIC Jinshi, and the overall valuation of the company reached $1 billion.

This is a pre-advertised product show. On the one hand, as a new product, it takes an educational process for design to go to the consumer market, and Spring Festival Evening Harmony is the best market promoter of product design. On the other hand, humanoid robots with excellent appearance and tonality in line with business scenes help to drain variety shows and offline shopping malls and tell a more technological brand story.

However, far from the performance of financing aura:In the field of domestic leasing, the product design with good sales performance is actually a wheeled flat-panel robot dominated by domestic Da Yun robots.

SoftBank Pepper, similar to Da Yun, receives robots.

In contrast, Ubisoft’s best-selling commercial reception robot is not a humanoid, but a Cruzr robot that also provides information consultation with a large tablet computer.

The choice of enterprises is clear-cut: avoiding the humanoid design with higher cost and more instability at this stage, and realizing offline service efficiency through AI voice and content. As for whether the product design is bipedal and conforms to the humanoid ideal of designers and engineers, it is not for enterprises to consider.

In any case, the B-end products support the valuation confidence of the industry. In April 2019, the representative of domestic humanoid robot, You Bixuan, started filing counseling at Shenzhen Securities Regulatory Bureau and started the journey of IPO listing.

At this moment, it is less than 10 months before the full-scale outbreak of the COVID-19 epidemic.

Epidemic prevention medical care, failed answer sheet

When the epidemic spread around the world, the design route of humanoid robots was also subverted.

Faced with such a large-scale epidemic and the emerging demand for massive service robots, designers suddenly found that wheeled robot talents are the solution to deal with the epidemic quickly.

The medical robot of Cizhi Wei ‘an has no obvious humanoid bipedal design.

As a result, there is no doubt that all kinds of unmanned vehicles have played a far more important role than humanoid robots. After 2020, humanoid robots are absent from both epidemic prevention service robots and rehabilitation service robots released in 2022.

European and American designers from the other side of the ocean, without China and Japan’s attachment to the biped scheme, adopted the wheeled design scheme "pragmatically". At this point, the stage of epidemic prevention and medical service has been decoupled from the design of humanoid robot.

The epidemic in COVID-19 seems to have nothing to do with humanoid robots, but it seriously overdraws the design funds-humanoid robots that are difficult to make profits in the short term and break through the technical bottleneck are even more backward in product application.

Entertainment and IP

The ebb tide of humanoid design does not seem to affect the surrounding IP and film and television products.

Why can today’s humanoid design still occupy a place? Essentially, humanoid robots are still enjoying the afterglow of all kinds of capital, media and IP. It has always been the global animation and film industry that has a profound impact on the product design of manufacturing industry, not the other way around.

When Takahashi Chihiro, the designer of the current article, was still studying at Ritsumeikan University in Kyoto, the Gospel Warrior of the New Century was already popular in East Asia, and at this moment, it has been 30 years since the humanoid robot Astro Boy was first serialized.

IP has a great influence on public cognition and product design.

When the design of humanoid robots lacks depth and fails to meet the public’s expectations of various classic IP, no matter how much design efforts, it will become a market failure. When one consumer story after another is finished, the humanoid robot persists except for the IP stage, and the audience on other stages has already gone empty.

The only purpose of design seems to be to stimulate investment.

Brand window telling vision

As the ceiling of humanoid design technology, Boston Power is probably a bumpy demonstration of stimulating investment.

Long ago, Boston Dynamics stated that it was, is and will be a money-burning company for a long time.

Although it has solved the problem of humanoid motion performance well enough, it has changed hands three times in seven years, and it has successively moved to Google, Softbank and Hyundai, which accurately illustrates the embarrassing situation that humanoid design lacks profit: enterprises are more inclined to use it as an imaginative tool to mobilize investment value, and once its revenue fails to meet expectations, it will be cut decisively.

This is similar to the underlying logic of Xiaomi’s project to build cars and robot products. Regardless of the impact of releasing humanoid robot products on business, it is definitely timely in stock price and future vision.

Xiaomi CyberOne Design Conference Site

This means that Xiaomi’s brand imagination has a new short-term anchor object.

Today’s Tesla has also learned how to pull this stock price. Musk clearly knows what the brand story about Tesla’s next decade looks like.

Today’s industrial design can’t solve the dilemma that humanoid robots are not popular, and Tesla is not optimistic. Various cost and scenario application problems will also be an urgent problem for Tesla designers.

Facing the Unknown Screenshot of Optimus Prime Tesla Conference

The Design Bonus of Sunset Western Hills

In the history of industrial design all over the world, no design team has completely run through the difficult design road of humanoid robots. How to design a humanoid robot? Musk, peter teale and Kai-Fu Lee have no answers, there is no answer in the history of industrial design, there is no answer in bionic design, there is no answer in motor parameters, and there is no answer in data algorithm.

In any case, humanoid robots will always inspire industrial designers deeply: try not to let backward product forms and concepts guide product appearance and creativity.

Jian li, senior product manager of Hetai, believes that the future prospect mainly lies in the service scene function of the companion.Humanoid has never been an efficient productive form, so when designing products, don’t be bound by the evolution process of carbon-based life, so that the efficiency of robots can not be limited to humanoid.

Nina, director of Naiyang’s creative design and operation, said: After the iPhone came out, all the industrial designs of the old era, such as the touch screen slider, disappeared. The category of "smart phone" has also been settled after years of competition. If Tesla’s "Optimus Prime" can become an iPhone-like classic design and have a profound impact on the industry, even if it is wheeled or modularized and detachable, it is very different from the "humanoid" imagined by consumers. As long as the market opens, everyone will slowly accept the new design.

Before the design proposition of human modeling, not only Tesla designers, but also product designers all over the world may be thinking: can humanoid robots get rid of the unnecessary conceptual constraints and break the original appearance ideas?

The answer to this design proposition will probably affect Tesla and other humanoid robots in the next decade or even twenty years.

Boxster’s past lives. It brought Porsche back to life.

  [History of car home Cars] Today, Porsche is one of the most profitable car manufacturers in the world. However, in the 1990s, it suffered a serious crisis and almost went bankrupt. How did Porsche get out of the predicament step by step and realize its legendary revival? Among them, (|), the two-seater roadster to be discussed in this paper, plays a decisive role.

Home of the car

  In the early 1990s, although Porsche owned three models, 928, 911(964) and 968, the sales situation was not satisfactory, which caused the company to fall into a terrible business crisis. In order to save the enterprise, Porsche has carried out drastic reforms. On the one hand, Toyota production mode is introduced to save costs and improve production efficiency.

  On the other hand, adjust the product range, stop production of the expensive 928 and 968 equipped with front-mounted 4-cylinder engine, and instead develop a sports car with more attractive price that can capture the hearts of young consumers. In addition, in order to raise more funds, Porsche and Audi jointly built a high-performance station wagon RS2 and designed a sedan C88 for the China market.

  In 1991, Porsche, which was in deep crisis of survival, tried various solutions, including a two-seat convertible concept car with a mid-engine layout-Boxster. The design of the car was inspired by the concept car Panamericana built by Ferrari Porsche on his 80th birthday. The short rear suspension and short body, the front suspension extending forward and protruding from the front axle and the exhaust tailpipe arranged in the center of the rear of the car continue the classic design of Porsche.

  Boxer is a combination of the words "horizontally opposed engine" and "roadster". This name contains the initial setting of horizontally opposed engine, which is also a prominent technical feature shared by the 356 models launched in 1948 and the 911 models from 1963 to the present. The concept of mid-engine is derived from the predecessors 550 Spyder, 914/6 and 718 racing cars.

Home of the car

  Boxster concept car is equipped with Porsche’s first mass-produced water-cooled horizontally opposed six-cylinder engine, with an initial displacement of 2.5 liters and a maximum power of 204 HP. Because of the water cooling system, four valves and variable intake timing, its design meets more stringent emission standards. The car’s innovations also include a balanced weight distribution, a quick-opening movable roof, a braking system derived from racing, and the best drag coefficient (Cd=0.31) in its class.

  The research and development work is in full swing. According to Grant Larson, the designer in charge of Boxster concept car, "We originally planned to show our concept car at the Geneva Motor Show in the spring of 1993. But we decided to choose Detroit in January because we didn’t want to waste any time. More importantly, our focus on sports cars was on the American market, when Porsche did not perform well in the American market. Mazda Miata and BMW Z1 have already appeared in the market. "

  The Boxster concept car unveiled at Detroit Auto Show was very popular. "Boxster received overwhelming praise from the public and experts, which obviously had an impact on development," Grant Larson continued. "Shortly after the exhibition in Detroit, we were asked to stop the design and development of Boxster immediately, and instead, we were asked to produce it as a concept car!" Time has proved that this is a wise decision.

  In October 1996, Porsche Boxster was officially released, which filled the gap of entry-level models below 911. It is worth mentioning that Boxster is not only manufactured in Zuwenhausen factory in Stuttgart, but also subcontracted to Valmet company in Finland, which is the first time that Porsche models have been produced outside Germany since the early Austrian factory.

Ali announced a coaching change: Zhang Yong will step down and they will take over.

  The Paper reporter Yang Yang

  The rumors of Alibaba Group coaching change have landed.

  On June 20th, Zhang Yong, Chairman and CEO of Alibaba Holding Group, announced through a full letter that the brand-new business cluster of Ali 1+6+N has basically taken shape, the boards of directors of various business groups have started to operate, and the listing and financing plans of multiple businesses have also been carried out. The holding group will mainly assume the role of innovation incubation base camp.

  At the same time, Zhang Yong announced that the complete spin-off of Alibaba Cloud Intelligent Group has started, and it is in the most critical period of upward development, so we must devote ourselves wholeheartedly. At the same time, in order to adapt to the future development norms and requirements, it is not appropriate for him to serve as chairman and CEO of the two companies at the same time. With the approval of the Board of Directors of Alibaba Holding Group, Zhang Yong will step down as Chairman and CEO of the Board of Directors of Alibaba Holding Group on September 10th this year. After that, Zhang Yong will be the full-time chairman and CEO of Alibaba Cloud Intelligent Group, focusing on the development of Alibaba Cloud, continuously enhancing Alibaba Cloud’s industrial competitiveness and global competitiveness, and allowing Alibaba Cloud to provide better, safe and convenient basic services for the digital intelligence upgrade of various industries, especially small and medium-sized enterprises.

  At the same time, with the approval of the board of directors of Alibaba Holding Group, Cai Chongxin, executive vice chairman of the group, will be the chairman of the board of directors of Alibaba Holding Group; Wu Yongming became the CEO of Alibaba Holding Group and continued to serve as the chairman of Taotian Group.

Ali announced a coaching change: Zhang Yong will step down and they will take over.

  On June 20th, Zhang Yong officially started the handover with Cai Chongxin and Wu Yongming.

  This year is the sixteenth year that Zhang Yong has worked in Ali. Zhang Yong joined Ali as the CFO of Taobao in 2007, became the CEO of Alibaba Group in May 2015, and became the Chairman of the Board of Directors of Alibaba Group in September 2019. Since December last year, he also served as the president of Alibaba Cloud Intelligent, and was directly in charge of nailing.

  Jack Ma, founder of Alibaba Group, spoke highly of Zhang Yong. In 2019, when Ma Yun stepped down as the chairman of Ali’s board of directors, he published an open letter, in which he wrote, "(Zhang Yong) has demonstrated outstanding business talent and firm and calm leadership since he became the CEO of Alibaba Group, and achieved healthy and sustained growth in Alibaba’s performance for 13 consecutive quarters."

  "Alibaba’s relay torch was handed over to him and the team he led. I think this is the most correct decision I should make now. My cooperation and cooperation experience with Zhang Yong in recent years has made me full of confidence in him and the new generation of Alibaba leadership team he led! "

  For the new successor, Zhang Yong also expressed his support in an open letter. He wrote, "Cai Chongxin (Joe C.
Tsai) will succeed me as Chairman of the Board of Directors of Alibaba Group, Eddie Yongming.
Wu) will succeed me as CEO of Alibaba Group. Both of them are founders and partners of Alibaba. They have made important contributions to the historical development of Alibaba Group and have rich experience. I believe that under their leadership, the company can move towards a more brilliant future. "

  Cai Chongxin is Ma Yun’s most trusted entrepreneur and is currently the executive vice chairman of Ali Group. From the establishment of the company in 1999 to 2013, he served as CFO of the group, and in 2014 he led the company to go public in new york, and then he was responsible for strategic investment.

  Wu Yongming has served as the chief technology officer of many important businesses such as B2B, Taobao and Alipay, and led the construction of the underlying technical architecture of related businesses. Led the creation of the group’s core business, Ali Mama Platform, and the innovation hatched the mobile phone Taobao, which promoted the wireless of the group.

  More than two months ago, Alibaba announced the establishment of a "1+6+N" organizational structure, that is, under Alibaba Group, six business groups and a number of business companies were established, including Alibaba Cloud Intelligent, Taobao Tmall Business, Local Life, International Digital Business, Rookie and Big Entertainment.

  According to the "listing timetable" of Alibaba Group’s sub-board, Alibaba Cloud will be split up and listed independently in the next 12 months, and Cainiao and Box Horse will be listed within one and a half years, and the international digital business group will start external financing.

  It is worth noting that some media reported that in late May, Ma Yun called the business leaders of Taotian Group and held a small-scale communication meeting. Dai Shan, CEO of Taotian Group, Hai Wang (flower name: Qigong), Liu Peng (flower name: Aowen) and Liu Yiman (flower name: Yiman), the head of Taobao live broadcast, Cheng Daofang (flower name: Daofang) were present.

  Ma Yun said at the meeting that the methodology that Ali used to rely on for success may no longer be applicable and should be quickly changed. He pointed out three directions for Taotian Group: returning to Taobao, returning to users and returning to the Internet. In addition, Ma Yun believes that Taotian should be further flattened in organization.

  Zhang Yong, Chairman and CEO of Alibaba Group, sent a full letter on June 20.

  Dear Ali people,

  Since I became the CEO of Alibaba Group in May 2015, I have always written several letters to you every year. Maybe everyone is used to it. When you see the letter I sent to all employees, you will know that there are important changes in the company. I wrote to you again today, which brought you an important change about myself.

  Since the "1+6+N" organizational reform was announced in March this year, all the work is progressing smoothly and orderly. When the financial report was released last quarter, we announced the composition of the boards of directors of various business groups, and at present, all the boards of directors have started to operate. We also announced a number of plans for various business groups and business units, including the complete spin-off and listing of Cloud Intelligence Group from Ali Group, the listing of Cainiao Group and Box Horse, and the independent financing of overseas digital business groups. The whole Alibaba is heading for the future with a new attitude.

  As we all know, the development of core technologies such as cloud computing, big data and artificial intelligence will bring great changes to society, which is of great strategic significance. At present, the complete spin-off of Cloud Intelligence Group has started, and it is at the most critical moment, which requires me to devote myself to it. At the same time, considering the requirements of standardized corporate governance during the spin-off, I personally should no longer be the chairman and CEO of both groups. Therefore, the board of directors of Alibaba Group discussed and accepted my request: from September 10, 2023, I will no longer serve as the chairman and CEO of Alibaba Group, but concentrate on doing the work of chairman and CEO of Alibaba Cloud Intelligent Group full-time. At the same time, the board of directors of Alibaba Group decided that Cai Chongxin (Joe
C. Tsai) will succeed me as the chairman of the board of directors of Alibaba Group, Eddie Yongming.
Wu) will succeed me as CEO of Alibaba Group. Both of them are founders and partners of Alibaba. They have made important contributions to the historical development of Alibaba Group and have rich experience. I believe that under their leadership, the company can move towards a more brilliant future.

  This change is not only for the company, but also for me personally, which is the beginning of another new stage and a new journey. How time flies! This year is my sixteenth year in Ali. I have been traveling together for 16 years, especially since I took over as CEO of the Group in 2015 and Chairman of the Board of Directors of the Group in 2019. It is precisely because of your trust, support, encouragement and tolerance that I have devoted myself to this position that I never imagined. I am sincerely grateful and grateful to you. In the past 16 years, because of the opportunity of social progress and market development, I have the honor to witness the historical stage of Alibaba’s rapid development with you, and participated in many creations that have benefited ordinary people’s lives from scratch, from small to large, from the digital process of enterprises to the beautiful society; Together with all of you, we have withstood the challenges of COVID-19 epidemic in recent three years and various tests brought by external environmental changes. No matter in good times or bad times, we not only grew up together, experienced together and spent together, but also gained a lot of friendship and friendship more valuable than our career.

  In the past 24 years, we have had many such moments of self-change. Now, we all stand at a new starting point together and start a new stage of future development through self-transformation. I believe that everyone will support the work of Joe and Wu Yongming and other senior students in the new group. Everyone can find their own stage and their own career, and finally contribute to society, achieve the company and achieve themselves. I will also stand on a brand-new stage with the students of Cloud Intelligence, and explore the new technologies of cloud computing, big data and artificial intelligence to serve the huge prospect of digitalization and intelligence in thousands of industries. I am full of longing and expectation for this.

  Castle peak will not change, green water will flow forever, create a new river and lake, meet again, and be happy!
