The masters attending the premiere of "Dong Chengxi on 2011" stood up and applauded to pay tribute to this meritorious director.


18 years ago, "East into West" can be described as a classic.

  Movie network news(Photo/Qian Jiayi/Yang Yaru) Although 18 years have passed, no one who has seen it will forget Tony Leung Chiu Wai’s sausage mouth, Joey Wong and Leslie Cheung’s flirting swords, the big boots on Zhong Zhentao’s head, the phrase "banana, you are a guava" and the funny performances of big names such as Jacky Cheung, Brigitte Lin, Maggie Cheung and Carina Lau. This popular film was shot in Liu Zhenwei in 27 days. Recently, Liu Zhenwei was at the premiere of the film, revealing the reason for the lack of shooting time, all because of Wong Kar-wai’s harm.


Classic stills of "East into West"


Now we can only appreciate the elegance of a generation of superstar Leslie Cheung through movies.

  "East into West is a movie I hate most, because I had to finish it in 27 days without a script, which was really painful." Liu Zhenwei looked a little sad. Referring to the reasons for being forced to be helpless, Liu Zhenwei revealed that it was all because of the snail speed of Wong Kar-wai’s filming. "I wanted to shoot &lsquo at the earliest; Ashes of time ’ The story when I was young, and then I called Wong Kar-wai. He said that it was very good. After we found the investment, Wong Kar-wai was responsible for shooting the first episode, and I will shoot the second episode. "

  Liu Zhenwei sighed, "As a result, a month passed, and I went to Wong Kar-wai’s crew to watch it again. He was still filming the scene on the day when he turned on the phone 30 days ago. I was so anxious that I was sweating. Later, the date of film delivery was approaching, and Wong Kar-wai said to let me shoot a top film quickly, so that he could finish the filming, so I only spent 27 days filming" East into West "and didn’t expect the film to sell well.


Tony Leung Chiu Wai’s classic sausage mouth


At that time, the cast of "East into West" was extremely luxurious, and it also became a swan song throughout the ages.


Zhong Zhentao’s classic stills in "Dong Cheng Xi Jiu" were released at the premiere of "Dong Cheng Xi Jiu 2011".

  As for the new version, Liu Zhenwei said, "Although I hate it the most, a reporter told me a few years ago that she would watch this movie regardless of her emotions, which moved me very much, so I told her that I would shoot a new one for them, so there was 2011."

  Liu Zhenwei said, "2011 is not just funny like the last one. This one adds a lot of warmth, and these warmth things come from Leslie Cheung. Leslie Cheung and I are very good friends, and I hope my brother can see 2011, which is also a memorial to him. " Liu Zhenwei said emotionally, "I hope everyone can feel the spirit of Liu Zhenwei: always love the people and things around us."

  It is reported that "2011 East into West" will be released nationwide on November 24th, which brings together Zhong Zhentao, Karen Mok, Eason Chan, Crystal, Deng Lixin, Kimi, Sitar tan and other stars.

How Nano-soldiers Fight Cancer —— Do you know?

Cancer, as one of the most common diseases with high mobility and high mortality in the world, the clinical treatments for its tumors generally include surgery, chemotherapy and radiotherapy. Due to the shortcomings of chemical drugs and various toxic and side effects, people have been committed to developing more effective drug delivery systems for cancer treatment, with the aim of reducing side effects and ensuring its efficacy.

With the progress and maturity of nanotechnology, its advantages are gradually reflected.

Introduction of nano-drugs

Diagram of sustained release process of nano-drugs

Nano-drug and its delivery system

Nano-medicine refers to nanoparticles or nano-carriers, which is a new product produced by the combination of nano-technology and medicine.

Nano-drug delivery system refers to the integration of small drug molecules into nano-materials by means of encapsulation or adsorption.

Advantages of nano-drugs

First, improve the solubility and absorption of drugs.

Nano-sized drugs are different from most chemotherapy drugs. Nano-sized drugs have larger specific surface area, better solubility, faster dissolution, improved absorption properties and better therapeutic effect.

At the same time, due to better solubility, the dosage of patients can also be appropriately reduced.

Second, prolong the drug’s circulation time in vivo, and enrich it to the focus.

Through some modification and treatment on the surface of nano-drugs, the circulation time of drugs in human body can be prolonged, which is beneficial for drugs to reach the lesion site, and special modification may make drugs more concentrated in the tumor site, resulting in better selectivity and targeting properties.

Nano-drugs can enter the tumor tissue through the porous blood vessels of the tumor, and achieve a high degree of penetration and retention in the tumor. Therefore, nano-preparation has excellent properties of high drug loading rate, passive targeting and controlled drug release.

Clinical application of nano-preparation.

Paclitaxel albumin nanoparticles

Paclitaxel is a commonly used anticancer drug in clinic. Here is a brief introduction to the nano-preparation of paclitaxel:

Paclitaxel, a commonly used anticancer drug

Albumin nanoparticles

Albumin nanoparticles are nano-particles based on albumin.

Albumin is an endogenous natural product with the advantages of safety, non-toxicity, non-immunogenicity, biodegradability and good biocompatibility. Moreover, the nanoparticle carrier system has unique targeting, sustained and controlled release characteristics and drug protection.

By high-pressure homogenization, paclitaxel and human serum protein preparation were made into nanometer freeze-dried powder, which can improve the solubility, avoid a large number of paclitaxel nanoparticles aggregation, and help the drug to be absorbed into tumor cells and give full play to its role.

Pharmacological action of paclitaxel

Paclitaxel is an anti-microtubule drug, which can stabilize microtubules by promoting the polymerization of tubulin dimer and inhibiting its depolymerization, thus inhibiting the normal dynamic reorganization of microtubule network during interphase and mitosis.

In addition, paclitaxel can lead to abnormal arrangement of microtubule "bundles", affect the division of tumor cells and promote tumor cell apoptosis during the whole cell cycle and cell mitosis.

indication

The application of albumin nanoparticles in the in vivo delivery of paclitaxel and cancer treatment has become a hot topic in recent years.

Albumin paclitaxel nanoparticles are mainly suitable for the treatment of metastatic breast cancer that failed in combination chemotherapy or breast cancer that recurred within 6 months after adjuvant chemotherapy.

Unless there are clinical contraindications, an anthracycline anticancer drug should be included in previous chemotherapy.

matters need attention

In the process of using paclitaxel albumin nanoparticles, it should be noted that paclitaxel for injection (albumin binding type) also has adverse drug reactions and must be used under the guidance of a doctor with chemotherapy experience.

Only with perfect diagnosis and treatment facilities can the complications and adverse reactions caused by drugs in treatment be effectively controlled.

Highly contagious! Emergency reminder in many places!

  recent days

  Many disease control departments have issued reminders:

  Winter is the most common season for chickenpox.

  The disease is highly contagious.

  The key to prevention is vaccination against varicella.

  This is also the most economical and effective measure.

  Chickenpox is known as "face to face biography"

  Kindergartens and primary schools are prone to collective outbreaks.

  Chickenpox is an acute respiratory infectious disease characterized by a rash caused by the initial infection of varicella-zoster virus.

  The disease is highly contagious, and people are generally susceptible to chickenpox. About 90% of susceptible people get sick after contacting patients, commonly known as "face-to-face transmission", which is easy to cause outbreaks, especially in infants and school-age children.

  Chickenpox has an acute onset, with symptoms such as fever, headache, fatigue, nausea and vomiting in the prodromal stage. After 1-2 days, a rash appears, with more on the trunk, less on the limbs, head and face, and less on the palms, soles and oral mucosa, which can be differentiated from hand, foot and mouth disease. Can be secondary to bacterial infection, pneumonia, encephalitis, hepatitis and other complications.

  Chickenpox is a self-limited disease with a natural course of 7-10 days. After the disease, it can gain lasting immunity. Isolation treatment should be carried out after the illness, until the chickenpox and herpes are all dry and scabbed, or not less than one week after the illness.

  Life-long immunity can be obtained after illness, sometimes the virus remains in the ganglion in a static state, and herpes zoster occurs after years of infection recurrence.

  Vaccinate against chickenpox

  Is the most effective means of prevention.

  1. Vaccination can effectively prevent varicella caused by varicella-zoster virus infection. The main target of vaccination is susceptible to varicella at the age of 12 months and above. Generally, vaccination for about 2 weeks can play a protective role.

  2 to carry out monitoring, strengthen the morning and afternoon inspection, kindergartens and schools found suspicious children should immediately take measures such as isolation, medical treatment, disinfection of supplies. Clear isolation period should be until all patients with varicella and herpes are dry and scabbed.

  3. Teachers and staff should maintain good personal hygiene, and classrooms and dormitories should be well ventilated.

  4. Clean and disinfect toys, personal hygiene products (cups, towels, etc.) and tableware; Disinfect activity rooms, bedrooms, classrooms, door handles, stair handrails, desktops, bathrooms, etc.

  5. Publicity and education; Use radio, blackboard newspaper, gallery and other forms to publicize the knowledge of prevention and treatment of respiratory diseases and improve students’ awareness of self-protection.

  Jiangsu can be vaccinated with varicella vaccine for free.

  Chickenpox is an infectious disease caused by varicella-zoster virus, which can occur all year round and is highly contagious. In recent years, routine monitoring of infectious diseases shows that public health emergencies related to chickenpox account for more than 80% of all public health emergencies related to infectious diseases, and all of them occur in kindergartens and schools, seriously affecting children’s health and normal teaching and living order. At the same time, the chickenpox epidemic in kindergartens and schools is easy to spread to communities and families, resulting in a wider spread.

  In order to effectively reduce the incidence of chickenpox, reduce the occurrence of public health emergencies caused by chickenpox, and prevent the cluster epidemic of chickenpox, with the consent of the provincial government, since January 1 this year, Jiangsu Province has included live attenuated chickenpox vaccine in children’s immunization program, and school-age children can be vaccinated with 2 doses of live attenuated chickenpox vaccine for free.

  Routine immunization procedures are as follows:

  The first dose was inoculated at the age of 12 to 18 months, and the second dose was inoculated at the age of 4. The interval between two doses of indirect inoculation is not less than 3 months.

  All school-age children born after January 1, 2017, who are included in the management of Jiangsu Children’s Vaccination Information System and have lived for more than 2 months can be vaccinated free of charge.

  Parents can bring their children to the vaccination clinic of the local community health service center for an appointment.

Handling of Proposal No.20220291 of the Fifth Session of the 12th CPPCC National Committee of the Autonomous Region

Suggestions: Suggestions on vigorously improving the local matching rate of automobile parts and enhancing the overall competitiveness of automobile industry chain.

Automobile industry is an important industry in Guangxi and a pillar industry in Liuzhou. Liuzhou is one of the important automobile industry gathering places in China, with four automobile enterprises including SAIC-GM-Wuling, Dongfeng Liuqi, faw liberation Liuzhou Branch and Guangxi Automobile Group. In 2021, the estimated output value will exceed 175 billion yuan, and the automobile production and sales will reach 1.88 million and 1.89 million respectively, among which the output of new energy vehicles will exceed 480,000, up 157.6% year-on-year.

At present, the automobile industry is facing an unprecedented change in a hundred years, and the automobile industry chain in the whole region is facing great challenges:

1. The layout of the "Three Electricity" industrial chain of new energy vehicles in Guangxi is not perfect, and the supporting system and R&D capability of the whole industrial chain of vehicles have not been upgraded. There are shortcomings in supporting local intelligence, networking, domestic chip components and intelligent driving control systems. For example, in 2021, leading enterprises in Guangxi’s new energy automobile industry, such as SAIC-GM-Wuling and Dongfeng Liuqi, are facing the problem of strong market demand but shortage of core components (control chips, power batteries, engines, etc.), and the satisfaction rate of SAIC-GM-Wuling core chips is only 30%.

Second, the core industrial chain is underdeveloped, and the localization, research and development and manufacturing capabilities of core components such as high-performance engines for passenger cars, automatic transmissions, and new energy vehicles "Three Electricity" need to be improved. The intelligent manufacturing level of local supply chain is not high, and the production operation efficiency can not meet the future competition. Take SGGM-Wuling as an example, the automation rate of its supporting suppliers in Liuzhou is about 30%, which is half that of supporting suppliers in Chongqing; The completion rate of digital factory transformation is less than 10%.

4. In recent years, Liuzhou City has successfully explored the "Liuzhou Model" for the promotion and application of new energy vehicles through the linkage between government and enterprises. In 2021, the autonomous region also introduced relevant policies for the promotion of new energy, but the promotion and application of new energy passenger cars and commercial vehicles in other cities still need to be further strengthened.

5. The competition in the new energy automobile industry will be more intense. The number of new energy automobile main engine plants has reached more than 76, and the traditional automobile giants have launched brand-new new energy vehicles. At the same time, the electric replacement models and hydrogen battery models of commercial vehicles of major automobile enterprises have also appeared. It is estimated that the output of new energy vehicles will reach 5 million in 2022.

The new energy automobile industry has become the key field of the future competition of the world automobile industry. Promoting the transformation and upgrading of the automobile industry in Guangxi is particularly important for the development of Guangxi during the "Tenth Five-Year Plan" period. It is urgent to introduce more key projects, create more competitive parts products, maintain the stable operation of the industrial chain, improve the local matching rate of automobile parts and enhance the overall competitiveness of the automobile industry chain.

To this end, it is suggested that:

First, make the industry leader bigger and stronger, and improve the driving ability and efficiency. Give full play to Liuzhou’s role as a pioneer of high-quality industrial development in the whole region, and relevant departments of the autonomous region will increase policy support and land use security to promote the strong chain, supplementary chain and extension of Liuzhou’s new energy automobile industry chain. We will increase the layout of the independent controllable capacity of the automobile industry chain led by SAIC-GM-Wuling and Dongfeng Liuqi, support the accelerated development of new energy vehicle projects, and constantly improve new energy platforms, large and medium-sized logistics vehicles, HEV energy-saving vehicles, commercial vehicles, trams and hydrogen energy commercial vehicles, enhance local basic process design, research and development capabilities and manufacturing capabilities, and consolidate the foundation of the automobile and equipment manufacturing industry chain. In five to eight years, the local matching rate will gradually increase by more than 15%, the output value of new energy automobile industry will increase by 50 billion yuan, the output value of high-tech and high value-added supply chain will increase by more than 20 billion yuan, and the total automobile production and sales will increase by 5% every year, and the market share in the country will reach more than 10%, and the total output value will increase by more than 100 billion yuan.

Second, relying on the leader to promote the gathering of industrial chain elements of the new four modernizations. In combination with the 14th Five-Year Plan of Guangxi Automobile, the relevant departments of the autonomous region, aiming at the weak points of the "new four modernizations" industrial cluster, have issued targeted policies and measures for attracting investment, carried out precise investment and special investment, attracted leading enterprises in the new energy automobile industry to settle in Liuzhou, strived to introduce a number of "three power" and intelligent networked supply chains, planned chip packaging, testing and application localization projects synchronously, and gradually built a new four modernizations with complete elements.

Third, improve the level and support the digital and intelligent upgrading of the industrial chain. Strengthen the cooperation of the government, scientific research institutions, enterprises and other parties, build leading enterprises, promote the intelligent upgrading of the industrial chain, focus on cultivating core enterprises such as SEEK Technology, focus on the upgrading of intelligent workshops and smart factories, accelerate the construction of industrial Internet, deepen the cost reduction and quality improvement of the automobile industrial chain, and enhance the competitiveness of the existing local parts market; Vigorously build a public service platform for intelligent manufacturing, support enterprises to carry out technological innovation, mechanism system innovation and business model innovation, and stimulate enterprise innovation and creativity.

Fourth, strengthen the promotion of new energy vehicles and cultivate the development environment of new energy vehicles in Guangxi. Pilot application of "Liuzhou Model for Promotion and Application of New Energy Vehicles" in various cities in the whole region, and promote and apply new energy commercial vehicles, urban logistics vehicles, special vehicles and other vehicles in ports, factories and mines and long-distance trunk transportation in conjunction with Guangxi Automobile Group, Dongfeng Liuqi and Heavy Duty Truck Transportation; Promote the application of new energy sanitation vehicles in urban and rural areas; Introduce financial leasing companies and other models, start commercialization pilots, and promote the application of new energy logistics vehicles in the fields of postal services, express delivery, and e-commerce terminal logistics; Give full play to the advantages of intelligent new energy vehicles and actively promote the transformation and upgrading of new energy commercial vehicles and special vehicles to participate in the intelligent transformation of ports, factories and mines.

Five, the implementation of the policy, increase the introduction and cultivation of high-end talents such as the "new four modernizations". Support, guide and encourage OEMs to strengthen the construction of innovative teams, implement the talent strategy of "going out" and "bringing in" in parallel, and continuously consolidate the stability and development of talent teams. On the one hand, we will build talent enclaves and R&D enclaves, break geographical restrictions, and gather industry elites to contribute to industrial chain construction. On the other hand, we will further optimize the talent introduction and education policy, improve the talent development environment, improve the talent care and protection policy, and strive to build a high-end innovative talent team with key core technologies, lead the industrial development, and promote the transformation and upgrading of the industrial chain, and strive to maintain the stability of high-end and special talents in enterprises.

Focusing on the leading enterprises in the automobile industry, we will increase the layout of independent and controllable capabilities in the automobile industry chain. The autonomous region issued the Work Plan for Promoting the Transformation, Upgrading and Development of the Automobile Industry, the Notice on Improving the Local Matching Rate of Automobile Parts, the Notice on Printing and Distributing the Work Plan for Making SAIC-GM-Wuling Leading Enterprises Form the Whole Industry Chain of Liuzhou Automobile, and the Notice on Printing and Distributing the Work Plan for Making Dongfeng-Liuzhou Leading Enterprises Form the Whole Industry Chain of Liuzhou Automobile. Liuzhou has issued such policy documents as Implementation Plan for Transformation and Upgrading of Liuzhou Automobile Industry, Several Measures for Promoting the Development of Mould Industry in Liuzhou City and Several Measures for Promoting the Development of Casting and Forging Industry in Liuzhou City, which strongly support the construction of strengthening, supplementing and extending the chain of Liuzhou automobile industry chain.

In recent years, Liuzhou’s automobile industry has overcome the adverse effects of rising raw materials, repeated epidemics, chip shortage and power shortage, and gradually realized the transformation from traditional fuel vehicles to new energy vehicles. The production and sales volume have rebounded year by year, and the automobile production and operation of the OEM have achieved good results. In 2021, SAIC-GM-Wuling produced 1.672 million vehicles, up 8% year-on-year, of which 458,000 new energy vehicles were sold, up 157.5% year-on-year. Dongfeng Liuqi produced 200,000 vehicles in 2021, up 11.2% year-on-year, including 125,000 passenger vehicles, up 35.6% year-on-year. At present, there are E100/E200/E300 new energy automobile products produced in Liuzhou.

/E300Plus/ Hongguang MINI EV, S50EV, G100 logistics vehicles, Dongfeng Liuqi new energy power exchange vehicle, Dongfeng Liuqi hydrogen fuel commercial vehicle and other new energy vehicle products, and the products are gradually serialized.

Liuzhou plans to build a well-known domestic R&D and production base for the whole industrial chain of new energy vehicles in about five years, and build a well-known domestic new energy automobile city in Guangxi, with a production and sales scale of over 2 million vehicles and an output value of over 170 billion yuan. The production technology of complete vehicles and main parts enterprises has reached the domestic leading level. In the next step, several key projects will be implemented in the new energy automobile industry: First, the "two million" new energy automobile platform project of SAIC-GM-Wuling. Invest 30 billion yuan to build two platforms of millions of new energy vehicles, pure electric vehicles and hybrid vehicles, accelerate the localized production of the industrial chain of new energy vehicles, and realize the new output value of more than 100 billion yuan. Second, Dongfeng Liuqi new energy transformation project. Invest 4.3 billion yuan, strive to sell more than 10,000 new energy vehicles such as hydrogen fuel heavy trucks, and realize the new output value of new energy heavy trucks of more than 12 billion yuan. The third is the transformation project of new energy vehicles of Guangxi Automobile Group. Invest 3 billion yuan to develop the new energy logistics vehicle market, form three major product series of passenger cars, trucks (modified vehicles) and off-road vehicles, and at the same time promote the OEM plan of new energy passenger cars, achieving an additional output value of more than 10 billion yuan. Fourth, the new energy automobile industry chain extension and chain repair project. Invested 12 billion yuan, introduced Qingshan Ruipu power battery, United Automotive Electronic New Energy Vehicle Controller, Wuhan Yuanfeng ABS Controller and other projects, with an added output value of more than 50 billion yuan.

(B) on "relying on leading enterprises to promote the new four industrial chain elements gathering" proposal.

Liuzhou insists on promoting the electrification, intelligence and networking development of the automobile industry as an important direction to promote the transformation and upgrading of the automobile industry. Relying on the continuous improvement of the new energy automobile product market of SAIC-GM-Wuling and Dongfeng Liuqi, Liuzhou has carried out accurate investment promotion and accelerated the layout of supporting industrial chains. Liuzhou Guoxuan Hi-Tech New Energy Battery 5 GWh Project, Huating Power Battery Pack Production Line and Liuzhou Shuanglin New Energy Motor Project were completed and put into operation, SAIC-GM-Wuling built the first automobile controller production line, Sykes hybrid engine was developed, Penghui new energy storage project and Sykes Ruipu new energy battery project started construction, and the United Electronics Phase III new energy electric control drive project and Nexter new energy parts project were signed. Taking the construction of the car networking pilot area as an opportunity, we will increase investment attraction and introduce 8 industrial projects related to intelligent networking. The industrial chain construction of new energy vehicles has achieved good results, and various major core components have been put into production one after another. At present, local production of major components such as new energy power batteries, drive motors, bridges and controllers has been realized.

In the next step, in accordance with the relevant requirements of investment promotion of key industrial chains in the autonomous region and Liuzhou, we will continue to further promote the project of supplementing and strengthening the chain, especially for the upstream of new energy vehicles and intelligent network connection, and gradually build a new four-oriented industrial chain with complete elements.

(C) Suggestions on "upgrading the level and supporting the digital and intelligent upgrading of the industrial chain"

Liuzhou steadily promotes the construction of key industry platforms, with automobiles and construction machinery as the main line, and government and enterprises work together to support leading enterprises in the industry to build industry-level industrial Internet platforms and promote the digital transformation of upstream and downstream enterprises in the industrial chain. SAIC-GM-Wuling digital supply chain collaborative intelligent industrial Internet platform has been included in the pilot demonstration project of the Ministry of Industry and Information Technology for three consecutive years, and has been popularized and applied in more than 700 parts enterprises. More than 900 enterprises have carried out procurement collaboration on Guangxi machinery industry Internet platform built by Liugong. The Cheheyun Industrial Internet Platform built by Guangxi Automobile Group has been applied by more than 700 suppliers.

(D) Suggestions on "Strengthening the promotion of new energy vehicles and cultivating the development environment of new energy vehicles in Guangxi"

Liuzhou actively supports the local automobile main engine factory to carry out the promotion and application of new energy vehicles, and has formed the "Liuzhou model" for the promotion and application of new energy vehicles. In 2019, Liuzhou City and 13 other cities in Guangxi jointly launched the "Guangxi New Energy Vehicle Promotion and Exchange Series" to jointly explore and practice the "Guangxi Model" for the promotion and application of new energy vehicles, cultivate and expand the new energy vehicle market in Guangxi, and achieved remarkable results. By the end of March 2022, the total output of various new energy vehicles was 935,000 and the total sales volume was 916,500; The number of new energy vehicles is 122,700, accounting for 12.31%; Built 1016 charging pile sites and 11378 charging piles (2032 fast charging piles and 9346 slow charging piles); 530 public charging socket stations, 7041 public sockets and 17357 personal sockets have been built.

In the next step, Liuzhou will continue to accelerate the development of the new energy automobile industry, encourage SAIC-GM-Wuling and Dongfeng Liuqi to speed up the development and listing of new energy products, realize the increase in sales of new vehicles as soon as possible, and at the same time seize the favorable opportunity of the national new energy vehicles going to the countryside, accelerate the construction of charging infrastructure in counties and townships under the jurisdiction of Liuzhou, create a favorable environment for the promotion of new energy vehicles in counties and townships, and promote the extension of the promotion and application of new energy vehicles to counties and townships. At the same time, actively strive for the support of the autonomous region, increase the promotion and application of the "Liuzhou model" in the whole region, and create a good environment for the promotion and application of new energy vehicles produced in Liuzhou.

(V) Suggestions on "implementing policies and increasing the introduction and cultivation of high-end talents such as the" new four modernizations "

Liuzhou has issued some policy documents, such as "Several Measures for Accelerating the Gathering of Talents in the New Era in Liuzhou" and "Detailed Rules for the Classification of Talents and the Implementation of Incentive Subsidies in Liuzhou (Trial)", to increase the introduction of talents. From October 1, 2018, the city will achieve the goal of total talents exceeding 1 million in five years, including 100 high-end talents, 3,000 senior management talents, 3,000 doctors and masters, and high-skilled talents. According to different levels of talents, preferential treatment is given from salary, living allowance, housing purchase (rental) allowance, children’s enrollment and other aspects.

In 2022, Guangxi New Energy Automobile Laboratory settled in Liuzhou. Through joint innovation of politics and Industry-University-Research, it focused on five major sectors, namely, technical research, product development, intelligent manufacturing, industrial chain and ecological construction, and built the highest level and level of scientific and technological R&D innovation platform in Guangxi, creating a whole-chain R&D innovation base, a new highland for industrial talents training and a source of industrial ecological model in the whole region, and accelerating the "double-chain" integration of industrial chain in innovation chain. At the same time, in the process of layout of science and technology projects, guide local car companies to carry out joint research with universities, research institutes, key laboratories and other units, set up talent cultivation indicators, strengthen the construction of talent teams, and enhance the R&D and innovation capabilities of enterprises. In the introduction of high-level talents, we should pay more attention to the accurate introduction of talents, pay attention to the introduction of high-end innovative and entrepreneurial talents, achieve a benign interaction between talents and industries, and achieve a win-win situation for the development of talents and industries and enterprises. At present, four high-level talent projects in the automobile industry have been introduced to Liuzhou, including two B-type talent projects, one D-type talent project and one E-type talent project.

Goodbye to the Ape: Seven million years ago, at the "fork in the road", he went to the human side.

On July 18, 2018, Dakar, Senegal, the Museum of Black Civilization. Xinhua News Agency reporter Yan Yanshe   

Seven million years ago, in the active primate community in Africa, a figure stood up and took a small step for the individual at the "fork in the road" when the apes were about to leave, but it became a big step for mankind.

Today, this "fork in the road" is located in a remote desert in Chad. The skull left by that figure has been fossilized by the years and inadvertently exposed in front of people in the sand.

"This is the earliest known ancient human," Michel Bruehne, the leader of the fossil discovery team and a professor at the Institut fran? aise, said in an interview with Xinhua News Agency recently. "His name is Toumai, which means" hope of life "in the local language.

What is Man: The Controversy Faced by Tumai

Tumai’s skull fossil was discovered by Bruehne’s team in 2001. The original is now in the National Research and Development Center of Chad, and the replicas are exhibited in the National Museum of Chad and the Senegalese Museum of Black Civilization. Aimei Contusan, the chief researcher of the Museum of Black Civilization, said: "Tumai is considered to exist between the primate chimpanzee genus and the human genus." This expression reflects the controversy that Tumai once faced.

The facial image reconstructed from Tumai’s skull can directly explain the controversy. The hair and facial features on the reconstructed head look a bit like orangutans. Experts believe that Tumai is a male, and his fossils show the mixed characteristics of apes and humans: the skull shape is similar to that of apes, the brain volume is close to that of chimpanzees, and the orbital spacing is similar to that of gorillas.

Only three months after Bruehne’s team published a paper on Tumai in the British journal Nature in July 2002, milford Wolpov of the Paleoanthropology Laboratory of the University of Michigan and others published a questioning article in Nature in October, arguing that Tumai was still an ape rather than a human being.

However, there is also a lot of evidence to support that Tumai is a human being. Bruehne published a response article in Nature in 2005. He told reporters: "Some people say that this is a gorilla, and the canine teeth will be hollow and very large, but this is the canine teeth of human beings. The position of the foramen magnum on the skull is also different from that of gorillas and chimpanzees, but it is in line with the characteristics of human legs walking upright. "

"What is a person?" Wu Xiujie, a researcher at the Institute of vertebrate paleontology and Paleoanthropology, Chinese Academy of Sciences, pointed out in an interview with Xinhua News Agency that the focus of relevant disputes is actually the definition of human beings.

"Before the 1960s, paleoanthropologists generally used whether they could make tools as the boundary between humans and apes. However, it was later discovered that making tools is not a unique ability of human beings, and animals such as chimpanzees can also make tools. Therefore, paleoanthropologists gradually adopted a new standard: habitual walking with two legs upright. "

Wu Xiujie said that the position of the foramen magnum of Tumai’s skull is as downward as ours, indicating that the skull is vertically located on the spine, indicating that it has habitually walked upright with two legs. "This is decisive evidence." She said that the current academic classification of Tumai is the Sahelian Chad species. Although it does not belong to the genus of modern people, it belongs to the human family, which is the same as other ancient humans.

On April 8, 2009, several primary school students watched the reduced image of human ancestor fossil "Lucy" at the National Museum in Addis Ababa, Ethiopia. Xinhua News Agency reporter Deng Jianshe 

"The Ape": The Fork of 7 million years ago

Since Tumai is a human being, its "age" is particularly meaningful. Bruehne’s team published a paper in the Journal of the National Academy of Sciences in 2008, saying that the dating result of Tumai skull is between 6.8 million and 7.2 million years, which is often said to be 7 million years for convenience. He said: "So far, no human beings older than this have been found."

This means that the time of human origin has been pushed forward by Tumai.

For many years, Lucy, a famous ancient human fossil, has been called "the old grandmother of mankind". This female skeleton fossil, discovered in Ethiopia in 1974, is highly valued for its completeness and antiquity. Fossils include skulls, ribs, arm bones, etc., and are the most complete fossils of their kind. Its "age" is about 3.5 million years, and it has been firmly in the top spot in the world for a long time after being discovered.

But older fossils have appeared one after another. An ancient human fossil found in Kenya in 2000 was named Millennials because of its discovery time. It was about 6 million years ago and won the throne of "the highest generation". Only one year later, Tumai was discovered in Chad, which pushed forward the time of human origin by 1 million years.

The significance of Tumai is not only in time, but also in space. Before Tumai, because important early human fossils such as Lucy were found in eastern Africa, Yves Copon, a famous French paleoanthropologist, put forward the theory of "East Story", which believed that human beings originated in the east of the Grand Canyon in East Africa. Tumai appeared in the desert of Chad in central Africa and moved about 2500 kilometers west of the Grand Canyon, breaking the theory of "East Story".

"Tumai’s discovery shows the progress of scientific research," Contusan said. "With the further development of science and technology, we may find more ancient humans."

On August 8, 2019, Michel Brunet, a professor at the French Academy, was interviewed in his office in Paris. Xinhua News Agency reporter Gao Jingshe

The blind touch the elephant: the evolutionary tree of ancestors has not yet been explored

Tumai, who stood 7 million years ago, is the earliest ancestor we can see now. Is he our ancestor?

Ordinary people may naturally have such an idea. In Chad, most people know Tumai and are proud of it. Abubakar Saleh, a citizen of Chad, said: "Tumai is the ancestor of mankind, and we are the descendants of Tumai. This is a great honor."

But in the opinion of experts, the evolutionary tree of human ancestors is far from clear. Wu Xiujie said: "Because of the scarcity of fossils, our research on the evolutionary tree of ancient humans is still blind."

Now, a mainstream view in paleoanthropology is the "African origin" of early humans, because all the ancient human fossils found 2 million years ago are in Africa. "Human beings have spent a long time in Africa," Bruehne said. From a very long time scale, "we are all Africans, and outside Africa, we are all immigrants".

However, there is still controversy in academic circles about how modern people originated in more recent places. For example, for the ancestors of Chinese, there is an international view that although there were Yuanmou people 1.7 million years ago and Peking Man 770,000 years ago, these ancient humans may not have survived the Ice Age, and another group of ancient humans came out of Africa about 60,000 years ago.

Recently, however, many new fossil evidences have been found in the paleoanthropologists in China, such as Xu Changren, Dao County Man, Huanglong Cave Man, Chongzuo Homo sapiens Cave Man, etc. about 100,000 years ago. These new fossil evidences challenge the view that there are no modern people in China earlier than 60,000 years.

Wu Xiujie said: "The evolution of ancient human branches is not an isolated and linear process, but a complex bush-like process. There may be a mixture between branches, some branches may later perish, and new branches may arise somewhere. The trunk and panorama of the human evolutionary tree have not been explored yet. "

It is not clear whether Tumai is the ancestor of today’s modern people, even the Chadians. Wu Xiujie said: "But if we look at it from a particularly long time scale, we can say that Tumai and all of us modern people are relatives."

Expand the scope of subsistence allowances, increase the price subsidies for people in need, and effectively grasp the bottom line of people’s livelihood.

A few days ago, the the State Council executive meeting deployed measures to increase the basic living security of the people in need, so as to secure the bottom line of people’s livelihood.

At the regular briefing on the State Council policy held by the State Council Office on August 26th, Yang Yinkai, deputy secretary general of the National Development and Reform Commission, introduced that from September this year to March next year, the linkage mechanism of price subsidies will be adjusted in stages, and the policy of "expanding the scope of protection and lowering the starting conditions" will be implemented, so as to increase the price subsidies for the needy people and effectively grasp the bottom line of people’s livelihood. It is estimated that the policy will cover 67 million people after the expansion.

One-time living allowance will be issued to people with difficulties such as the minimum living allowance, which will be fully completed by the end of August.

Since the beginning of this year, the bottom-up safeguard measures have been continuously improved, and the assistance to the people in need has also increased. By the end of June this year, 40.62 million people had received assistance from urban and rural residents, including 7 million urban residents and 33.62 million rural residents. The national urban minimum living standard is 734 yuan per person per month and the rural minimum living standard is 554 yuan per person per month; In the first half of this year, the accumulated expenditure on subsistence allowances was 92.62 billion yuan.

In order to implement the requirements of "expanding the minimum living allowance and increasing efficiency", the civil affairs department has continuously improved the minimum living allowance system. Liu Xitang, director of the Social Assistance Department of the Ministry of Civil Affairs, said that seriously ill and severely disabled people in marginal families have been included in the subsistence allowance alone, forming a combination of household insurance and personal insurance, and the system has more capacity; Encourage all localities to decentralize the examination and confirmation authority of subsistence allowances from the past counties to streets and towns to improve the efficiency of examination and verification; In addition, for low-income families whose per capita income exceeds the local minimum living standard after employment, a gradual retirement period of six months to one year will be given.

The temporary assistance system is mainly aimed at solving the sudden, urgent and temporary basic living difficulties encountered by urban and rural people. Since the beginning of this year, affected by epidemic and disaster, the number of people in need has increased. A few days ago, the the State Council executive meeting requested that the one-time living allowance issued to the needy people such as the minimum living allowance should be paid in place as soon as possible.

Residents, including migrant workers, who are unable to return to work due to the epidemic, have no income for three consecutive months, and are not included in unemployment insurance, can apply for a one-time temporary relief fund at their place of residence or domicile. Liu Xitang said that the work is progressing smoothly. Seventeen provinces in the country have all paid out, and all localities have issued an additional subsidy of 8.08 billion yuan for 40.18 million low-income recipients and extremely poor people, accounting for 90% of the total number of people in need. "It is expected that the work will be fully completed by the end of August, and the total amount of funds distributed is expected to be close to 10 billion yuan."

This year, the central government allocated 154.68 billion yuan to help the needy, an increase of 7.06 billion yuan over last year, and the local budget also increased investment accordingly. In the first half of the year, the national financial expenditure totaled more than 120 billion yuan, up 7% year-on-year.

Liu Xitang said, "Social assistance funds such as subsistence allowances are the focus of people’s livelihood security, and they are also the focus of financial support. It is no problem to implement special fund management and timely and fully distribute social assistance funds such as subsistence allowances."

The linkage mechanism of price compensation expands the scope of protection and reduces the starting conditions, which is expected to benefit about 9 million more people.

From January to July this year, China’s consumer price index (CPI) rose by 1.8% year-on-year, and rose by 2.7% year-on-year in July. Yang Yinkai said that due to factors such as imported inflationary pressure and seasonal increase in pork prices, the domestic price level may be slightly higher than that of the previous months in the latter months of this year to the first quarter of next year, which is lower than that of cardinal utility in the same period last year.

In order to alleviate the impact of rising prices on the basic livelihood of people in need, the linkage mechanism of price subsidies will be adjusted in stages from September this year to March next year.

After the adjustment, the scope of protection has been expanded. The current linkage mechanism of price compensation covers seven groups, including urban and rural minimum living allowances, destitute people, people receiving unemployment insurance benefits, special care recipients enjoying regular state pension subsidies, orphans, children who are actually left unattended and children infected with HIV, totaling about 58 million people.

On the basis of the above-mentioned seven groups, this time, two groups, namely, people receiving unemployment benefits and marginal population with minimum living allowance, will be added into the scope of protection of the linkage mechanism of price compensation. After expanding the scope of protection, it is expected to benefit about 9 million more people and cover about 67 million people in need. Conditional places can further expand the scope of protection.

Wan Jinsong, director of the Price Department of the National Development and Reform Commission, introduced that the people receiving unemployment benefits and the marginal population with low living allowances will be included in the scope of protection in stages, mainly considering that the people receiving unemployment benefits are unemployed, their income sources are unstable, and their lives are facing certain difficulties; Although the income of the marginal population is slightly higher than the minimum living standard, the living standard is generally low.

After adjustment, the starting conditions are reduced. The monthly year-on-year increase of CPI in the starting conditions of the price subsidy linkage mechanism was reduced from 3.5% to 3.0% in stages, while other starting conditions such as issuing price subsidies when the food price in CPI rose to 6% year-on-year, were kept unchanged, and the price subsidy linkage mechanism was started when any conditions were met.

"Reducing the start-up conditions is mainly due to the impact of epidemic situation and disasters. The income growth of people in need faces more difficulties, and the feeling of rising prices may be more obvious." Wan Jinsong said that after lowering the starting conditions, it is expected that the number of months and the starting area of the price subsidy linkage mechanism will increase significantly, which means that more people in need can receive price subsidies.

All localities will grant temporary price subsidies of about 20 billion yuan to people in need.

According to statistics, since 2020, local governments have distributed temporary price subsidies of about 31.5 billion yuan, benefiting 530 million people in need.

After adjusting the linkage mechanism of price subsidies in stages, it is estimated that from September this year to March next year, all localities will provide temporary price subsidies of about 20 billion yuan to the needy, of which about 7 billion yuan will be increased due to expanding the scope of protection and lowering the starting conditions.

Where does the additional funds come from? According to reports, the additional funds for those who receive unemployment insurance benefits and unemployment subsidies are paid from the unemployment insurance fund; The central government will provide subsidies to other needy people in different regions, including 30% in the eastern region, 60% in the central region and 80% in the western region.

"Temporary price subsidies are issued by the local authorities first and settled by the central government." Wan Jinsong said, in the current situation that governments at all levels are living a "tight life", the state still decided to adjust the linkage mechanism of price subsidies in stages and increase the price subsidies for the needy people, which fully demonstrated that the CPC Central Committee and the State Council always cared about and cared about the needy people, and always placed the protection of their basic livelihood in a prominent position.

Yang Yinkai said that the National Development and Reform Commission will work with relevant departments to strengthen work guidance, ensure that all the work of price subsidies is carried out in an orderly manner, and ensure that policy deployment can be fully implemented. (Reporter Lu Yanan)

Chinese disease control: At present, the epidemic intensity is relatively strong, and the slow-growing population can be vaccinated again after evaluation.

  CCTV News:On the afternoon of December 13th, the State Council Joint Defense and Control Mechanism held a press conference. A reporter asked, some elderly people wanted to be vaccinated before, but they were assessed as inconsistent due to basic diseases and other reasons. Does this mean that they have not been vaccinated against COVID-19?

  Wang Huaqing, chief expert of immunization program of China CDC, responded that if there is a serious allergic reaction after vaccination, this kind of vaccine can’t be vaccinated again in the future, and most other situations belong to a slow vaccination scenario. In the early stage, because of the basic diseases, we assessed that it was impossible to vaccinate, and most of this situation belonged to delayed inoculation.

  He said that if this elderly person has a basic disease, he is in the early stage of attack, he is in a stable stage after a period of treatment, or he can’t be vaccinated because of special treatment. When the special treatment is over, these people can consider vaccination, especially in the current situation where the epidemic intensity is relatively large and there are many sources of infection, these people can be vaccinated again after re-evaluation and permission. The elderly should be well protected before they are vaccinated, and this kind of protection is also needed in the later period. If he enters the stable period of the disease and after the special treatment, it is recommended to vaccinate as soon as possible if he meets the conditions.

Children’s precocious puberty affects their physical and mental health. What does the doctor say?

  Evening News (Reporter Yan Li) For children who have not yet entered adolescence, precocious puberty is not a good thing, so many parents are concerned about it. Huang Le, chief physician of endocrinology department of Tianjin Children’s Hospital, suggested that the appearance of precocious puberty will not only hinder children’s growth and development, but also affect their physical and mental health.

  A sign of precocious puberty

  The precocious puberty signals of boys and girls are very different. Generally speaking, girls develop puberty before the age of 8 or boys before the age of 9, which can be preliminarily judged as precocious puberty. If a girl has breast enlargement, pubic hair growth, armpit hair growth, vaginal discharge increase before the age of 8 or menstruation before the age of 10, parents should pay attention to any of these changes, which is the signal of precocious puberty of girls. Before the age of 9, if boys have testicles and penises growing up, scrotal skin folds increase and the color deepens, penile erection increases, and even some boys produce semen, these are all signs of precocious puberty in boys.

  In addition, children’s precocious puberty has several characteristics, such as sudden increase in height, obvious development in a short time, and may have symptoms such as headache, vomiting and blurred vision. If children who have not entered adolescence have the above phenomenon, parents should also pay attention to it in time.

  The harm of precocious puberty

  The most obvious harm of precocious puberty is that it may affect the height of children. Adolescence is the fastest stage of children’s growth and development. If children have precocious puberty before puberty, it may affect their height development. Clinical cases show that some children with precocious puberty will greatly slow down their growth rate and their height will be shorter than that of normal children.

  Secondly, precocious puberty will affect children’s mental health, and children with precocious puberty may have some physical differences with children of the same age, which will have an impact on children’s psychology.

  Furthermore, precocious puberty may affect the development of children’s reproductive system. With the continuous improvement of people’s living standards and the improvement of dietary nutrition, children’s sexual development is now relatively advanced, so parents need to pay more attention to this aspect. In addition, the causes of children’s precocious puberty are complicated and influenced by many factors such as heredity, diet and environment, so it is more necessary to seek medical treatment as soon as possible, otherwise it is likely to affect the child’s future development.

  Prevention of precocious puberty

  In order to avoid precocious puberty, parents can adjust their children from the aspects of diet, exercise and sleep.

  Parents should pay attention to balance their children’s diet, and don’t have to deliberately emphasize fineness. It’s best to eat coarse grains and flour and rice in a balanced way. The doctor suggested that children should eat less snacks and eat some fruits in addition to the normal three meals a day, but they should not delay the dinner. Parents should drive their children to exercise moderately. Doctors suggest that when the weather is fine, parents should take their children outdoors for at least one hour at a time. Parents should urge their children to get enough sleep every day and try to sleep around 21 o’clock. Children generally need 10 to 12 hours of sleep every day, and at least 9 to 10 hours of quality sleep should be guaranteed.

  In addition, doctors remind parents that if children are found to have precocious puberty, they should go to regular hospitals in time, be tested by scientific diagnostic methods such as hormone level, B-ultrasound and CT, and be treated according to the doctor’s advice.

BYD: The Best Mid-year Report in History Encountered the Reduction of Stock God.

Only after handing over the best mid-year report in history, BYD (002594.SZ) immediately encountered the test of investor confidence by Buffett’s reduction.

Since 2022, BYD’s various businesses have generally been "opened". In terms of new energy vehicles, sales exceeded 100,000 vehicles for five consecutive months, and surpassed Tesla to top the global sales in the first half of 2022. At the same time, the installed capacity of power batteries has steadily increased. In May, it surpassed LG in the installed capacity ranking of global power battery enterprises and became the second in the world.

Under the blessing of two ace businesses and high market valuation, BYD ushered in an unexpected but unexpected Davis double click — — On June 10th, BYD’s total market value successfully exceeded one trillion, becoming the first domestic automobile brand with a market value exceeding one trillion.

But there were Ning Wang and Tesla before, followed by Wei Xiaoli. Can the trillion "Diwang" take the lead in the increasingly white-hot global new energy vehicle war and bring more imagination beyond the valuation of nearly 300 times?

Berkshire’s answer now seems to be no: for the first time in 14 years, it reduced its holdings by more than 6 million shares. There are still 219 million shares in hand, will the market outlook continue to cash out? This makes the market quite a bit floating.

Go back to the basic disk. BYD has been building its own winning weapon for many years — — The industrial chain layout and vertically integrated business structure have made it frequently criticized, and now it is highly respected and has become "the only company that has completely withstood the blockade, chip shortage and rising raw material prices".

After the profit turning point, whether BYD’s whole industrial chain layout can escort and promote its sustained high growth, and how unique industrial ecological landscape will be generated, this paper will deconstruct and analyze its two main businesses, new energy vehicles and power batteries, and find out.

The full text is long, mainly from the following aspects:

New energy vehicle business

1.1 Upstream chip: self-core-made, and it has become the power semiconductor faucet of domestic vehicle specifications.

1.2 Mid-stream auto parts: Can the "Foday System" be both internal and external?

1.3 intelligent mid-stream vehicles: self-research capability needs to be improved.

1.4 Downstream production base: The layout quantity is relatively advanced.

Second, the power battery business

2.1 upstream lithium ore and raw materials: self-production and equity participation.

2.2 Battery technology and key equipment are independently developed.

2.3 layout power battery recycling, trying to solve the demand for raw materials.

2.4 The production capacity continued to expand, adding multiple production bases.

I. New energy vehicle business

Cars are undoubtedly BYD’s most profitable business segment.

In the first half of 2022, BYD sold 646,400 vehicles, up 162.03% year-on-year, of which 638,200 were new energy passenger vehicles, up 324.84% year-on-year, and the domestic market share reached 24.7%, up over 7.5 percentage points from 2021.

In terms of revenue, in the first half of 2022, the proportion of automobiles, related products and other products in total revenue increased from 52.20% in the first half of 2021 to 72.55% in the first half of 2022, achieving revenue of 109.267 billion yuan, a year-on-year increase of 130.31%.

In terms of profit, BYD ended the situation of increasing income without increasing profit. In the first half of the year, it realized a net profit of 3.029 billion yuan, a year-on-year increase of 721.72%.

"BYD has a high configuration and a low price, so it sells well. After its market share is stable, it will gradually raise prices and its profitability will improve." A new energy fund manager said that the complete industrial chain layout has also promoted BYD’s profitability.

Wang Chuanfu once said that foreign suppliers despises new independent brands and can only rely on themselves at first. It is both a challenge and an opportunity. It is from the initial forced "self-production and self-supply" that BYD has stepped forward to the present.

1.1 Upstream chip: self-core-made, and it has become the power semiconductor faucet of domestic vehicle specifications.

In 2002, BYD set up the integrated circuit design department, which started almost simultaneously with its plan to build cars and batteries. In 2004, IT officially entered the field of microelectronics and optoelectronics in the IT industry, and BYD Microelectronics was established, which was later BYD Semiconductor. Recently, BYD Semiconductor has submitted a prospectus to Shenzhen Stock Exchange, intending to be listed on GEM.

BYD has been developing its own chips for 20 years, and now it has become the largest power semiconductor IDM enterprise in China. According to BYD Semiconductor’s prospectus, the company’s main business is divided into five sectors: power semiconductor, intelligent control IC, intelligent sensor, photoelectric semiconductor, manufacturing and service, and the revenue in 2021 accounts for 43.22%, 13.46%, 19.25%, 18.69% and 5.38% respectively.

Among them, the power semiconductor business with the largest proportion of revenue mainly adopts IDM business model, and has formed a complete industrial chain including chip design, wafer manufacturing, module packaging and testing, and system-level application testing. The products mainly include IGBT chips, FRD chips, IGBT modules, IGBT single tubes, IPM modules, SiC modules, etc., which are applied to new energy vehicles and other fields.

BYD Semiconductor has set up an IGBT R&D team since 2005. IGBT can convert direct current into alternating current, which is an indispensable device for new energy vehicles. At present, the company’s vehicle-class IGBT module has matched BYD’s new energy vehicles, and the total shipment volume ranks first in China, breaking the monopoly of overseas manufacturers.

At the same time, BYD Semiconductor is also the first power semiconductor enterprise in the world and the only one in China to realize the large-scale loading of SiC three-phase full-bridge modules in motor drive controllers of new energy vehicles. It has broken through technical problems such as high-temperature packaging materials, long-life interconnection design, high heat dissipation design and vehicle regulation level verification, and realized the large-scale application of SiC modules in high-end models of new energy vehicles.

Intelligent control IC products include MCU chip, power IC and BMSAFE chip. At present, Fabless business model is mainly adopted.

In the field of vehicle regulation MCU, BYD Semiconductor is also the first echelon in China. The company’s car-level 8-bit MCU chip has been mass-produced since 2018, and is mainly used in automotive electronic control scenes such as car lights and car buttons; The 32-bit MCU chip of vehicle regulation level is designed according to the requirements of ISO26262 safety level standard, and it integrates various communication modules, which can be applied to automotive electronic control scenes such as electric windows, electric seats, wipers, lights and instruments.

Wang Chuanfu once said that the electrification of automobiles has brought about great changes that have never happened in a hundred years, and the industrial supply chain system is bound to be reconstructed. "In the field of semiconductors, the demand for semiconductors in electric vehicles is 5-10 times higher than that in traditional vehicles. Electric cars are in the first half, smart cars are in the second half, and smart cars have greater demand for semiconductors. "

However, there are only a handful of car companies that make their own chips. After all, the research and development cycle is long and the investment is large, which is not cost-effective, especially the IDM model with heavy asset investment.

In the tide of core shortage that swept the world in the past two years, automobile chips were in the most shortage, especially the power semiconductor of automobile gauge and MCU in vehicle. The advantages of BYD’s self-made chips were fully reflected.

Can BYD Semiconductor supply in bulk to other car manufacturers in the future? At present, in addition to supplying BYD Group, its vehicle-grade power semiconductor products have entered the supply systems of manufacturers such as Xiaokang Automobile, Yutong Automobile, Foton Motor, Ruiling, Beijing Times, Invigorate, Blue Ocean Huateng and Huichuan Technology, but in 2021, the revenue from BYD Group still accounted for more than 60%.

1.2 Mid-stream auto parts: Can the "Foday System" be both internal and external?

"BYD’s overall supply chain was relatively weak during the epidemic. Some core components were done by its own business department, and the control of the supply chain was relatively in place." A new energy analyst of a brokerage recently said in an interview with CBN.

In March 2022, BYD launched an independent Foday brand and officially announced the establishment of Foday Company. The company has operational autonomy and the core components of new energy are sold to the outside world.

According to Wang Chuanfu, as a sub-brand of BYD, Foday Department is a complete auto parts supporting system, which is an inevitable choice for BYD after years of vertical integration. After the split, it will be priced according to the market-oriented mechanism to form a profit center.

On the one hand, Foday Company guarantees the safety of BYD’s industrial chain, on the other hand, it can broaden the company’s growth space through external supply, which is expected to open a second growth curve in the field of auto parts.

Up to now, BYD has five auto parts companies: Foday Mould, Foday Power, Foday Battery, Foday Technology and Foday Vision, and through these five companies, it has realized self-supply in the fields of power battery, electric drive system, electric vehicle platform, thermal management system, lighting system and battery management system.

In terms of batteries, since 2020, Foday Battery has established a number of "Foday Department" battery companies.

From Bengbu Fudi Battery Co., Ltd. in 2020 to Wuwei, Yancheng, Jinan, Shaoxing, Chuzhou, Fuzhou Fudi Battery Co., Ltd. and Chongqing Fudi Battery Research Institute Co., Ltd. in 2021, and then to Xiangyang, Taizhou, Nanning, and Guangxi Fudi Battery Co., Ltd. in 2022, the total number is more than ten.

In February 2022, the power battery project of FAW Fudi New Energy Technology Co., Ltd., which was jointly registered by China FAW Group and BYD, officially started. With a total investment of 13.5 billion yuan, the project can meet the configuration requirements of 600,000 electric vehicles every year after it is completed and put into operation, and realize an annual output value of more than 20 billion yuan.

In terms of electric drive, in March 2022, Skyworth Motor released the Skyworth HT-i model. Some insiders said that the Skyworth HT-i model adopted the HT-i system developed by Foday Power and Skyworth, and the HT-i system was tailored for Skyworth Motor.

As early as 2019, BYD released the "BYD New Energy Vehicle Parts Selection Manual", which externally supplied core components such as powertrain, motor, electronic control and power supply.

1.3 intelligent mid-stream vehicles: self-research capability needs to be improved.

BYD, which started from the traditional manufacturing industry, did not have the conditions to impact the high-end in the era of fuel vehicles. With the advent of the intelligent era, BYD’s self-research and foreign cooperation were driven by both, and it got the tickets for the second half in advance.

Yang Dongsheng, vice president of BYD and president of Product Planning and Automotive New Technology Research Institute, once said that the core of automotive intelligence lies in the intelligent cockpit. After three years of development, BYD’s DiLink system applied to the intelligent cockpit has launched version 4.0 in 2021.

Previously, in the second half of 2020, BYD Intelligent Networking Center also released DiPilot, an advanced intelligent driving assistance system for automobiles, for the first time, which includes DiDAS intelligent assistance technology and DiTrainer coaching mode.

At present, BYD’s main subsidiary, Foday Technology, is engaged in research related to intelligent cockpit, ADAS and vehicle networking. The specific products include multimedia systems, blind spot monitoring systems, automatic parking, panoramic images and intelligent forward-looking. At the same time, Foday Seiko has relevant layout in smart car, and its specific products are lighting combination headlights and rear lights, rearview mirrors, indoor and outdoor photo lamps, etc. In addition, the Automotive Smart Ecology Research Institute is engaged in the research and development of open smart car platforms, smart customer relationships and smart car applications.

However, compared with electrification, BYD’s intelligent self-research ability needs to be improved.

"It is difficult for BYD to make breakthroughs in intelligent driving and software systems. Now it is basically the world of Huawei and several foreign players." The above fund manager said. There are even more extreme voices saying that BYD’s shortcomings in the direction of intelligence are as obvious as its advantages in electrification.

Among them, hardware configuration and OTA (over-the-air download technology) are the main gaps between BYD and the new car-making forces.

The Qualcomm Snapdragon SM6350 chip used in BYD DiLink 4.0 platform is a mid-to high-end processor, while the mainstream cockpit chips of Tucki P5, Weilai ET7 and ET5 all use Qualcomm Snapdragon SA8155P chip. SA8155P chip is the top-level chip in Qualcomm, and it is in the first echelon in the automotive chip industry. At the same time, BYD has also faced problems such as upgrade trouble and poor user experience in OTA.

Judging from the layout of BYD’s R&D, it seems that the company really prefers electrification. In 2021, BYD’s R&D investment reached 10.63 billion yuan, a year-on-year increase of 24.20%. The projects involved mainly included blade battery technology, energy storage products (BMS-active) and DM-i super hybrid.

How will BYD handle itself in terms of intelligence?

At the same time of self-research, BYD chose to strengthen cooperation with the outside world in an effort to make up for the shortcomings of the industrial chain.

In 2018, BYD and Baidu Apollo signed cooperation agreements related to new energy vehicles, driverless technology and vehicle asset sharing operations.

In 2019, BYD signed a strategic cooperation agreement with Huawei, and BYD Han was equipped with Huawei HiCar;; In March 2021, the company strategically invested in Horizon, an automotive smart chip enterprise; In November 2021, Momenta, a company related to autopilot software, established a joint venture company "Dipai Zhixing" for high-level autopilot layout; In December 2021, it reached a strategic cooperation agreement with sagitar Juchuang (mainly engaged in intelligent lidar system), and officially led sagitar Juchuang in February 2022. In February 2022, Baidu was selected as the supplier of intelligent driving system; In March of the same year, it reached a cooperation with NVIDIA, and it is planned to install NVIDIA DRIVEHyperion platform on some vehicles in the first half of 2023 to realize a higher level of intelligent driving function.

1.4 Downstream production base: the layout quantity is relatively advanced.

In April 2022, when the epidemic was serious, BYD’s pure electric and plug-in hybrid products were ranked first in the sales of passenger car brands.

The reason why BYD’s sales volume can ride the dust, in addition to the materials needed for self-supply, the widely distributed production base also contributed.

Compared with enterprises such as Weilai, Ideality and Tesla, which have only one production base in China, BYD has built four automobile production bases in Shenzhen, Xi ‘an, Changsha and Changzhou. In June 2022, the first complete vehicle Qin PLUSDM-i of BYD Hefei Base Phase I was successfully rolled off the assembly line, and five other factories, including Fuzhou, were under construction. This means that once there is an emergency, BYD can minimize the risk of downtime.

According to the data of China Investment Network, as of May 2022, BYD’s annual production capacity has reached 1.3 million vehicles, and it is expected to reach 3.4 million vehicles in 2022. With the steady implementation of mass production plans of some factories, the vehicle production capacity will reach 4.05 million vehicles in 2023, and the scale effect will be further revealed.

It is reported that at present, BYD’s four bases in Jinan, Hefei, Zhengzhou and Shenshan all adopt the mode of "parts+whole vehicle", which can predict in advance to reduce the accumulation of parts and spare parts and reduce the stocking cost as much as possible.

Second, the power battery business

The struggle between Ferrous lithium phosphate and Sanyuan never stopped. Wang Chuanfu, who has worked with batteries for decades, insists that BYD can only find a way out in China and the world if it is Ferrous lithium phosphate. Despite the twists and turns, BYD finally won back the main battlefield of lithium iron phosphate battery with its high-performance blade battery.

According to the data of China Automotive Power Battery Industry Innovation Alliance, with the accelerated loading of blade batteries, the installed capacity of BYD power batteries increased from 16.2% in 2021 to 22.25% in the first seven months of 2022.

However, the financial report shows that in 2021, BYD’s secondary charging and photovoltaic business (including power battery business) achieved revenue of 16.471 billion yuan, a year-on-year increase of 36.72%; The gross profit margin was 11.94%, down 8.22 percentage points year-on-year.

To say who is holding back the profitability of power batteries, the high probability is the lithium mine whose price is "constantly rising". BYD’s power battery business has undoubtedly faced the challenge of high raw material prices since 2021. In fact, in order to stabilize the supply chain and control the battery cost, BYD has been trying to enter the upstream lithium mine field in recent years, and at the same time, it has intensified its efforts to lay out the middle-stream lithium battery equipment, downstream power battery recycling and other businesses.

2.1 upstream lithium ore and raw materials: self-production and equity participation.

In March, 2022, Wang Chuanfu said at the committee of 100 Forum on Electric Vehicles in China that the soaring price of battery raw materials was a challenge that the industry needed to overcome. He suggested that the layout and production capacity of lithium carbonate resources should be comprehensively sorted out, the domestic mining volume and foreign imports should be increased, and the price expectation should be stabilized.

BYD mainly arranges lithium resources by investing in lithium resource enterprises, establishing joint ventures with lithium resource enterprises, and directly purchasing lithium mine mining rights.

As early as 2010, BYD invested about 200 million yuan to acquire an 18% stake in Zabuye High-tech Lithium Industry Co., Ltd. in Shigatse, Tibet. According to the data, Zabuye High-tech Lithium Industry is a holding subsidiary of Tibet Mining and has the exclusive mining right of Zabuye Salt Lake for 20 years. The salt lake is the third largest lithium mine salt lake in the world and the largest in Asia, with proven lithium reserves of 1.841 million tons.

Since 2022, the company’s lithium resource layout has been more intensive. In January, BYD won the bid of $61 million for the Chilean lithium mine, but unfortunately the project was stopped by the local court; In March, it is planned to invest 3 billion yuan in Shengxin Lithium Energy. In April 2022, the company signed an agreement with Yinhe Lithium Industry to purchase 60,000 tons of lithium concentrate every year. At the same time, the planned new 60,000-ton lithium salt project in Indonesia is expected to be put into production in 2023. At the end of March, BYD Auto Industry, a subsidiary, invested 6 million yuan and held 30% of the shares, and set up a mining company with Sichuan Luqiao, aiming at developing Sichuan lithium mine resources; In May, it was reported that BYD had found six lithium mines in Africa, all of which had reached the acquisition intention. The output of lithium carbonate in these six lithium mines is reported to reach 1 million tons, which can cover the company’s raw material demand in the next decade.

As for cathode materials, BYD, as an enterprise specializing in lithium iron phosphate batteries, can imagine the demand for Ferrous lithium phosphate. Therefore, on the basis of self-research and self-production, the company also guarantees the supply through the mode of foreign equity participation.

In 2019, the Ecological Environment Bureau of Haidong City, Qinghai Province issued a public notice of environmental impact assessment, and accepted the construction project of Ferrous lithium phosphate with an annual output of 20,000 tons of Qinghai BYD Industrial Co., Ltd., with a total investment of 710 million yuan.

In July 2022, Anda Technology announced that BYD spent 30 million yuan to subscribe for the company’s directional issuance of shares, with a shareholding ratio of 2.11%. In addition, BYD also took a stake in Hunan Yuneng, another leading anode manufacturer in Ferrous lithium phosphate, with a shareholding ratio of 5.27%.

In addition to lithium ore and cathode materials, the company’s annual report revealed that a series of related businesses such as battery aluminum foil, aluminum-plastic film, separator and electrolyte additives were also laid out in the field of power batteries, and the upstream and downstream industries were continuously strengthened.

In 2021, North China Aluminum Company established a battery aluminum foil company, which attracted many battery companies to become shareholders, of which BYD held 2.97%.

Zijiang New Materials is one of the leading enterprises in the domestic aluminum-plastic film industry. In the second half of 2021, strategic investors such as BYD were introduced through capital increase and share expansion, and BYD directly held 3.87% of the shares. At the same time, BYD was the largest customer of Zijiang New Materials.

BYD’s diaphragm layout started as early as 2009, when the company and Foshan Plastic Group Co., Ltd. jointly expanded the lithium-ion battery diaphragm project with a total investment of about 105 million yuan. By August, 2016, BYD’s power battery separator has been partially produced.

In terms of electrolyte additives, in February 2021, BYD took a stake in Huasheng Lithium Battery, which had just been IPO, and held 1.98% of the shares.

2.2 Battery technology and key equipment are independently developed.

Insisting on being long and thin is the development direction of BYD’s battery technology.

The company’s main product, the blade battery, adopts the Ferrous lithium phosphate scheme of long battery cells, flattens the battery cells, and uses the module-free technology to form a battery pack, so that the utilization rate of the internal space is increased to about 60%, and the cost can be reduced by about 25%.

According to TF Securities, in November 2021, Foday battery ranked second in the domestic market share of power battery cells. Foday battery joint venture FAW Foday New Energy Technology Co., Ltd. is mainly engaged in the manufacturing of core components such as new energy batteries, modules and related supporting industries. After the factory is fully put into production, the annual production capacity of power battery can reach 45GWh, which will provide long-life blade batteries for more than 1 million vehicles.

Because the shape of the blade battery is different from that of the traditional power battery, the ready-made standard equipment can’t be used directly. BYD takes advantage of being a "tech man" and the equipment for key processes is developed by itself.

For example, the lamination process adopts the equipment and cutting scheme independently developed by BYD. The pole piece with a length of nearly 1 meter can achieve the accuracy and speed of tolerance control within ±0.3mm and single lamination efficiency of 0.3s/pcs, which is the first in the world. At the same time, self-developed equipment and systems are also used in the assembly and liquid injection.

2.3 layout power battery recycling, trying to solve the demand for raw materials.

In September 2015, BYD and GEM jointly established a recycling system of "material recycling-battery recycling-new energy vehicle manufacturing-power battery recycling". In January 2018, BYD signed a strategic partnership agreement with Tower Company for recycling new energy power batteries. At present, BYD has set up more than 40 power battery recycling service outlets in more than 10 provinces and cities.

In addition to solving the urgent demand for raw materials and reducing the cost of raw materials, another significance of the power battery recycling business is that it may open up a new growth curve for BYD.

Judging from the performance of battery recycling leaders GEM and Tianqi, in 2021, GEM’s power battery recycling business achieved revenue of 151 million yuan, a year-on-year increase of 61.63%; Jiangxi Tianqi Jintaige Cobalt Co., Ltd., the core subsidiary of Tianqi’s lithium battery recycling business, achieved an operating income of 988 million yuan in 2021, a year-on-year increase of 52%; The net profit of returning to the mother was 224 million yuan, a year-on-year increase of 622.58%.

According to the data, the business scope of Taizhou Fudi Battery Co., Ltd., a subsidiary of Fudi Power, includes battery manufacturing and sales, recycling and cascade utilization of waste power batteries in new energy vehicles, and research and development of new materials and technologies. At present, the company is indirectly wholly-owned by BYD Co., Ltd.

2.4 The production capacity continued to expand, adding multiple production bases.

"In 2021, the bottleneck of battery capacity had a certain impact on the mass production of the whole vehicle. With the production capacity of the battery base in 2022, the automobile production capacity will also increase. In April, the proportion of BYD’s loading on the battery side has reached 32.18%, and the gap with Contemporary Amperex Technology Co., Limited is gradually narrowing." The above analyst said.

Since 2021, BYD has successively expanded eight battery production bases in Jinan, Shandong, Wuwei, Anhui, Yancheng, Jiangsu, Wuhan, Hubei, Shaoxing, Zhejiang, Ningbo, Chuzhou, Anhui and Fuzhou, Jiangxi, with a total new production capacity of 205GWh. In 2022, bases in Xiangyang, Hubei and Changchun, Jilin were successively opened, and two base projects in Taizhou, Zhejiang and Nanning, Guangxi were signed.

In terms of production capacity, BYD plans to have a production capacity of 135GWh in 2021 and an available production capacity of 80GWh;; In 2022, the planned production capacity is 285GWh, and the available production capacity exceeds 200GWh;; By 2023, the planned production capacity will exceed 500GWh, and the available production capacity will exceed 350GWh.

The expansion of production capacity has also accelerated the process of BYD’s battery supply.

In 2018, BYD Power Battery only had two commercial vehicle customers, Taikai Automobile and Xugong Machinery. In 2019, the external supply of passenger cars was opened, and Changan Automobile, FAW and Changan Ford became new customers.

After BYD launched the blade battery in March 2020, it attracted more car companies to discuss cooperation.

In 2021, the external supply ratio of BYD power battery is about 10%. From the perspective of specific customers, FAW is the first third-party passenger car enterprise to adopt blade batteries, and BYD power batteries account for 25% of its total installed capacity; Dongfeng, Changan and BAIC use ternary batteries, and BYD’s supply accounts for 6%, 4% and 0.1% respectively.

Cinda Securities believes that with the increase of the acceptance of Ferrous lithium phosphate route, the external supply business is expected to usher in a substantial breakthrough, and the power battery business may become another important growth pole of the comparable automobile business.

Third, the conclusion

From about 60 yuan/share in June 2020 to a high of 358.86 yuan/share in June 2022, BYD’s share price has nearly tripled in just two years, which is supported by performance and the result of high valuation given by the market.

It can’t be denied that BYD seems to have opened up the second vein of Ren Du in the past two years, and the vertical integration layout that has been painstakingly managed for many years has soared to generate, resulting in great synergy, forming a virtuous circle of the whole industrial chain of new energy vehicles and constantly gaining positive feedback.

But after the market value once broke through one trillion, where is BYD’s next stop?

There were many optimists. Head brokers use the segment valuation method and think that the company’s reasonable value is 1.4 trillion yuan; There is also a view that new energy vehicles will be not only a means of transportation in the future, but also the next generation of intelligent terminals. If the new energy vehicle industry will produce a company with a market value of 2 to 3 times that of Apple’s stock, the market value of BYD may be trillions of dollars against Tesla.

Real money traders are obviously more rational. The latest market value of BYD’s A-shares has dropped to around 850 billion yuan, and the news that the stock god has reduced its holdings may further return it.

Charles Munger once said, "Wang Chuanfu knows what he can do and what he can’t do, while Musk thinks he can do anything. I prefer to choose those who have self-knowledge. " This is a high evaluation, but obviously, this does not affect Berkshire’s reduction of cash BYD, at the time he thinks it is appropriate.

Beijing CDC: Don’t abuse antibiotics when intestinal infectious diseases occur in summer.

  Xinhua News Agency, Beijing, August 20th (Reporter Xia Ke) Summer is the season of high incidence of intestinal infectious diseases, with high temperature and humidity, which is conducive to the reproduction of germs, and food is easily contaminated. People like to eat cold food to relieve summer heat, and the chances of infection are further increased. Beijing CDC reminds that attention should be paid to drinking water hygiene and food safety. High temperature can kill pathogenic microorganisms, and drinking water should be boiled before drinking. In addition, don’t use antibiotics as soon as diarrhea occurs. Abuse of antibiotics may lead to imbalance of normal intestinal flora, which is not conducive to recovery.

  According to reports, the main manifestations of intestinal infectious diseases are diarrhea, nausea, vomiting, abdominal pain, loss of appetite, etc. Serious cases can lead to dehydration, and very few cases are even life-threatening.

  Experts from Beijing CDC said that to prevent intestinal infectious diseases, first of all, food should be separated from raw food and cooked food to avoid cross-contamination. Leftover food should be stored in the refrigerator in time, and the storage time should not be too long. Before eating again, it needs to be heated until it is completely hot, because the low temperature of the refrigerator can only delay the growth of bacteria, but it cannot be sterilized. In addition, it is necessary to eat as little as possible foods that are easy to carry pathogenic bacteria, such as snails, shells, crabs and other aquatic products, especially seafood stalls on mobile roadsides, and products that are eaten raw or half-eaten. For families with pets, we must do a good job in pet hygiene, and at the same time, we must warn our children not to feed their pets while eating.

  Experts suggest that if diarrhea occurs, fasting and water restriction are not recommended, and light and digestible liquid or semi-liquid food should be eaten, and the symptoms will gradually transition to a normal diet after improvement. If diarrhea is not serious, the symptoms can be improved within 2 -3 days by adjusting diet, rest and symptomatic treatment. People with severe diarrhea, especially those with dehydration symptoms, should go to the hospital intestinal clinic for medical treatment in time. In order to prevent dehydration, you should drink more sugar and salt water, and it is best to buy "oral rehydration salt" at the pharmacy; Patients who have suffered from dehydration or severe vomiting and can’t drink water should go to the hospital in time and take intravenous rehydration and other treatment measures according to the doctor’s advice.

  Experts suggest that it is wrong for many patients to use antibiotics as soon as they have diarrhea. Because most diarrhea does not need antibiotic treatment, abuse of antibiotics may lead to imbalance of normal intestinal flora, which is not conducive to the recovery of diarrhea. If you are not sure whether antibiotics should be used, patients should go to the intestinal clinic.
