The sales volume of Yinlong New Energy Bus has fallen off a cliff, and Dong Mingzhu’s dream of building a car has fallen?

Recently, the information of Tianyancha and Qixinbao showed that many directors and supervisors of Yinlong New Energy Co., Ltd. (hereinafter referred to as "Yinlong New Energy") withdrew, including Dong Mingzhu, the chairman of Zhuhai Gree Electric Co., Ltd. At present, the main personnel of Yinlong New Energy are only Lu Chunquan and Lai Xinhua, and the chairman is Lu Chunquan and Lai Xinhua. At the same time, Lai Xinhua also holds the position of general manager.

Previously, the chairman of Yinlong New Energy was Lu Chunquan and the general manager Lai Xinhua; Directors are Dong Mingzhu, Deng Xiaobo, Peng Jihai, Sun Guohua, Wei Guohua and Wei Yincang; The supervisors are Yao Kejie, Hu Zhaowei and Zhang Wei respectively. Although Yinlong New Energy denied the withdrawal of many directors and supervisors, the information of Tianyancha and Kaixinbao changed.

However, Dong Mingzhu is still the second largest shareholder of Yinlong, holding 17.46%. The largest shareholder of the company is Zhuhai Yinlong Investment Holding Group Co., Ltd., holding 25.99% of the shares; Sunshine Life Insurance Co., Ltd. is the third largest shareholder, holding 11.60%.

Investment logic

Dong Mingzhu once looked at BOC Long’s lithium titanate battery and new energy vehicle business, and pushed Gree Electric to acquire Yinlong through private placement financing, but he was frustrated. Since then, Dong Mingzhu invested in Zhuhai Yinlong in his personal capacity, spending about 1 billion yuan and taking 17.46% of the shares in Yinlong, becoming the second largest shareholder of Yinlong. She also brought Wang Jianlin and Liu Qiangdong. She said at that time that the decision to invest in Zhuhai Yinlong was not aimed at profit, but hoped to support the rapid development of the new energy automobile industry.

At present, Yinlong’s main business is mainly new energy commercial vehicles. According to the latest data from China Bus Statistics Information Network, the sales volume of Yinlong New Energy Bus reached 2,708 in 2019, down by 62.8% year-on-year. It is worth noting that Yinlong New Energy relies too much on state subsidies. On April 25, 2019, Yinlong New Energy revealed on its WeChat WeChat official account that the former senior executives of Yinlong New Energy were suspected of defrauding the national financial subsidies for new energy vehicles, amounting to 112 million yuan.

Soon after Dong Mingzhu entered Zhuhai Yinlong, he began to expand rapidly and planned to go public. According to public information, Zhuhai Yinlong has signed nine industrial parks including Shijiazhuang and Luoyang, with a total investment of over 80 billion. The rapid expansion caused Yinlong to have overcapacity immediately. On the one hand, orders fell in a cliff-like manner, and a large number of finished vehicles in the factory were parked idle. On the other hand, it was constantly exposed that it was in arrears with suppliers’ payment. Yinlong was also terminated in 2018. IPO counseling. In addition, Yinlong New Energy has been listed as the executor for many times, and the contradiction between internal shareholders and management is constantly a magic weapon. In particular, the contradiction between Dong Mingzhu and Wei Yincang, the founder of Yinlong, intensified.

"The rapid expansion strategy and management turmoil aggravate the risks of L Yinlong New Energy, especially the changes in management, which will have a great impact on the company’s strategy and development rhythm." An industry person told reporters. Luo Lei, Deputy Secretary-General of china automobile dealers association, also said in an interview with CBN: "Yinlong mainly deals in passenger cars, but it is ok to concentrate on it. With the intervention of Dong Mingzhu, the degree of attention has become higher. However, buses are niche products, and the total supply is limited. Yinlong’s crazy expansion in the past two years has problems, and the development of enterprises should be steady growth to remain healthy. Expansion is based on the integrity of the whole system, which is closely related to scale, parts procurement and supply, production line, logistics and after-sales service. Once a link goes wrong, it will be fatal. "

Dong Mingzhu, who has always dreamed of building a car, has encountered many challenges due to the high threshold of the automobile industry, but she still insists that Yinlong’s battery can just become an indispensable and important role in Gree Electric’s smart home in the future.

Marginalization of lithium titanate battery

The most obvious label of Yinlong is lithium titanate battery technology. Official website of Yinlong New Energy shows that on September 20, 2010, Yinlong New Energy signed an acquisition agreement with American Aoti Nanotechnology Co., Ltd. (hereinafter referred to as "Aoti"), and on July 22, 2011, it strategically controlled Aoti. After that, Yinlong New Energy began to vigorously develop lithium titanate batteries in China with the help of Austrian titanium.

Compared with other battery technology routes, lithium titanate battery has advantages in safety and charging time. However, Wei Yincang also mentioned in public that when Aoti was acquired, the cost of lithium titanate was 12 times that of the current battery. Compared with BYD, the cost is 50%~60% higher, and the gap will be further narrowed with the expansion of production capacity.

In recent two years, the phenomenon that lithium titanate is marginalized is more obvious. According to the latest data of installed power batteries in 2019, the installed power batteries in China reached 62.2GWh, up 9.2% year-on-year. Ternary materials and Ferrous lithium phosphate occupied the main market share, while the installed capacity of lithium titanate battery only reached 0.38GWh, down 23.6% year-on-year.

"In fact, lithium titanate batteries were discovered earlier than ternary lithium batteries and lithium iron phosphate batteries. If possible, everyone has already made a choice." Fang Jianhua, senior consultant of Power Battery Application Branch of China Chemical and Physical Power Industry Association, said in an interview that lithium titanate battery has a fatal weakness: low energy density, which is directly related to the length of cruising range, but the density of lithium titanate battery can’t meet this requirement now. In addition, with the decline of subsidies, lithium titanate batteries are mainly used in new energy buses, and their capacity is relatively limited, which will bring greater challenges.

"Lithium titanate battery is a niche route, which can be used in some specific markets and cannot digest large-scale product production. For example, in a mountain city like Chongqing, it is used in the electric bus market and some power grid energy storage markets. Therefore, it is possible for the application of lithium titanate battery to grow moderately, and it is doomed to be difficult to explode quickly. The rapid expansion of Yinlong does not conform to the development law of lithium titanate battery itself, and the outcome can be imagined. " Mo Ke, founder and president of Real Lithium Research, told the First Financial Reporter that if we find the right market and then take it slowly, I believe that lithium titanate batteries will also have a place.

"Market choice determines the technical route. Especially after the cancellation of subsidies, the market is mainly private cars and short-distance cars, and it is estimated that it will still be dominated by three yuan. " Cao Guoqing, deputy secretary general of China Battery Industry Association, told reporters.

However, Dong Mingzhu, who was frustrated by Yinlong’s new energy, did not give up her enthusiasm for the automobile industry. Now she has chosen a relatively lightweight way to enter the automobile industry. On August 28th, 2019, Gree Electric’s subsidiaries Zhuhai Gree Energy Environment Technology Co., Ltd., Huatai Huineng (Beijing) Energy Technology Co., Ltd. and Yinlong New Energy jointly registered Zhuhai Hengqin Gree Huati Energy Development Co., Ltd. with a registered capital of 30 million yuan, and the main management was held by relevant personnel in Gree Electric. In September 2019, Gree Electric joined forces with five enterprises including Zhuzhou CRRC and Yinlong New Energy to jointly establish Guochuang Energy Internet Innovation Center (Guangdong) Co., Ltd.. Among them, Gree Electric holds 75% of the shares, Zhuzhou CRRC holds 8%, Yinlong New Energy holds 5%, and Dong Mingzhu serves as the chairman.

Nutrients refer to the chemical components in food that can provide energy for human body, repair the body and tissues, and have physiological regulation functions, and maintain human health and provide various substances needed for human growth, development and labor. The nutrients needed by human body are carbohydrates, protein, lipids, vitamins, minerals and trace elements, and water. In recent years, dietary fiber has been found to be the eighth kind of nutrients for human beings.

Carbohydrate is composed of three elements: carbon, hydrogen and oxygen. Because the ratio of hydrogen to oxygen is 2: 1, which is the same as water, it is named as the most abundant organic compound with broad-spectrum chemical structure and biological function in nature, which provides heat energy for human body and is the main source of energy needed by all organisms to maintain life activities. It is divided into two categories: effective carbohydrates that can be absorbed and utilized and ineffective carbohydrates that people can’t digest. The latter is dietary fiber, as described later.

Some carbohydrates also have special physiological activities, which are the main nutrients that provide energy for life activities (anaerobic glycolysis substrates of nerve tissues and red blood cells); Because it is eventually decomposed into sugar in the body, it is called sugar, which can promote the metabolism of other nutrients and have a special "nitrogen-saving" effect; Participate in the human body to form tissues and synthesize glycogen.

Protein molecules contain carbon, hydrogen, oxygen, nitrogen, and possibly sulfur, phosphorus and other elements. Alpha-amino acids are combined in a certain order to form a polypeptide chain, and then one or more polypeptide chains are combined in a specific way to form a polymer compound, which constitutes the scaffold and main substances of human tissues and organs and plays an important role in human life activities. It can be said that there would be no life activities without protein.

Amino acid is its basic constituent unit, which is formed into peptide chains through dehydration and condensation, and then is composed of one or more polypeptide chains and arranged in a certain order. This is protein. The amino acid sequence is encoded by the corresponding gene, encoding 20 basic amino acids. Some amino acid residues can be modified after translation to change the chemical structure, thus activating or regulating protein. A plurality of protein play a specific function by forming a stable protein compound, folding or spiraling to form a certain spatial structure. Synthetic peptides’s organelles are ribosomes on the rough endoplasmic reticulum in cytoplasm, and protein’s differences lie in the types, numbers, arrangement order and spatial structure of its amino acids. Protein constitutes the material basis of human cells, promotes the growth and tissue repair of the body, forms antibodies against diseases, maintains the osmotic pressure of the human body and transmits genetic information. The ingested protein is digested, hydrolyzed into amino acids and absorbed in the body, and then the protein needed by the human body is synthesized. The new protein is constantly metabolized and decomposed, and is always in a dynamic balance. The quality and quantity of protein in food and the proportion of various amino acids are related to the amount of protein synthesis, growth and development, prenatal and postnatal care, health and longevity, and are closely related to the amount of protein in diet. Protein can be divided into complete protein and incomplete protein. protein, which lacks essential amino acids or has little content, is called incomplete protein, such as protein in cereals and gelatin in animal skins and bones.

Fat is the general name of oil, fat and lipid. What is liquid at room temperature is called oil, and what is solid is called fat. Fat is composed of three elements, C, H and O, and is a triglyceride composed of glycerol and fatty acids. The molecule of glycerol is relatively simple. Fatty acids can be divided into three categories: saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids, or long-chain, medium-chain and short-chain fatty acids according to the length of carbon content. Fat is soluble in most organic solvents and insoluble in water. It is a glyceride of one or more fatty acids. The cell membrane composed of lipids separates the organelles from the surrounding environment, mainly provides macro nutrients for energy, and also has the functions of maintaining body temperature and protecting organs. Fatty acids are an important guarantee for the normal operation of the brain, immune system and reproductive system, and contribute to health and longevity. Fat lubricates body tissues and joints, and is also an important component of human body (phospholipid is an important component of biofilm). Cholic acid and steroid hormones have the functions of nutrition, metabolism and regulation. As the surface substance of cells, lipids are closely related to cell recognition, species specificity and tissue immunity. The digestibility of fat is related to its melting point. The more unsaturated fatty acids, the lower the melting point: the digestibility of vegetable oil reaches 100%. The melting point of animal fat is above 40℃, the digestibility is 80% ~ 90%, and the content of linoleic acid and linolenic acid in vegetable oil is relatively high, which provides essential fatty acids. Fat helps the absorption of fat-soluble vitamins a, e, k and d.

Vitamins are a kind of organic compounds necessary for maintaining health, and they are also a kind of regulatory substances. It is not the raw material of body tissue, nor the source of energy. It is an important active substance that plays an important role in substance metabolism and maintains human health. It can’t be synthesized in the body or the amount of synthesis is insufficient. The required amount is small but indispensable, and it must be supplied by food frequently.

Common ground of various vitamins:

① All of them exist in food in the form of provitamin;

② It is not a component of body tissues and cells, and does not produce energy, but mainly participates in the regulation of body metabolism;

③ Most vitamins can’t be synthesized by the body or the synthetic amount can’t meet the needs of the body, so they must be obtained from food frequently;

④ The human body needs a small amount of vitamins, once lacking, it will lead to corresponding vitamin deficiency.

Vitamins are divided into three categories: one is fat-soluble vitamins, which can be stored in the body, including vitamins A, D, E and K; The other is water-soluble vitamins, which need to be provided from food every day, including vitamins C, B1, B2, B6, B12, nicotinic acid (vitamin B3), pantothenic acid (calcium pantothenate), folic acid (vitamin B9), choline, biotin, etc. The third category is provitamin, whose chemical structure is similar to a certain vitamin, which can be converted into vitamin through simple metabolic reaction, such as β -carotene can be converted into vitamin A; 7- dehydrocholesterol can be converted into vitamin D3 and so on.

Vitamins account for a very small proportion in natural foods and are necessary for the human body. There are dozens of vitamins found now, which play an extremely important role in the metabolism, growth, development and health of the body and are important substances for maintaining and regulating the normal metabolism of the body. Many vitamins are coenzymes of enzymes or components of coenzymes. The best vitamins exist in human tissues in the form of "bioactive substances". Vitamins B6 and K can be synthesized by bacteria in animal intestines, and the amount of synthesis can meet the needs. Primates cannot synthesize vitamin C by themselves. Animal liver, eggs, dairy products, carrots, pumpkins, bananas, oranges and some green leafy vegetables are rich in vitamin A; Ingredients such as cod liver oil, eggs, margarine, milk and tuna are rich in vitamin D; Grain embryo, vegetable oil and green leaves are rich in vitamin E; Green leafy vegetables are rich in vitamin K; Sunflower seeds, peanuts, soybeans, pork, cereals and wild edible fungus Tricholoma matsutake are rich in vitamin B1. Meat, cereals, vegetables and nuts are rich in vitamin B2. Pig, beef, mutton, fish, poultry, shellfish and eggs are rich in vitamin B12;. Lemon, orange, apple, jujube, strawberry, pepper, potato and spinach are rich in vitamin C.

Minerals and trace elements are not exactly the same substance. Minerals are also called inorganic salts. Except for carbon, hydrogen and oxygen, the rest of the 60 elements in human body belong to minerals, accounting for more than 0.01 of the total weight of human body.

There are 11 kinds of essential macroelements for human body, such as calcium, aluminum, magnesium, sodium, potassium, iron, sulfur, phosphorus, chlorine, etc. Essential trace elements refer to elements that are necessary to maintain human life, development and reproduction, accounting for less than 0.01% of the total weight of human body and less than 100 mg a day. There are 14 kinds of elements such as iodine, copper, zinc, manganese, cobalt and fluorine, which play an extremely important role in regulating life metabolism.

Calcium-supplementing foods include milk and dairy products, beans and bean products, small fish and shrimp, bones and shells, kelp, seaweed, sesame seeds, sesame paste, etc. Phosphorus supplements are widely found in various animals and plants: lean meat, fish, poultry, eggs, milk and their products are rich in phosphorus, and nuts, kelp, laver, oilseeds and beans are also high in phosphorus. As long as there is enough protein and calcium in food, there will be enough phosphorus. Phosphorus absorption rate in cereal plants is low; Iron-supplementing food consists of animal liver, kidney, blood, red meat, beans, fungus and sesame paste. The high phosphorus protein in egg yolk will interfere with the absorption of iron, and the effect of iron supplementation is not very good. Zinc-supplemented foods are mainly found in shellfish such as oysters, red meat, animal viscera, dried fruits, cereal embryos, wheat bran, peanuts and peanut butter, eggs, bean sprouts, oats, etc. Strengthen iodized salt by eating iodized food seafood; Selenium-supplemented foods such as seafood and animal offal, such as caviar, sea cucumber, pig kidney, oysters and clams, are also high in wheat germ powder, purple peanuts, dried mushrooms, peas and lentils. Tea, marine fish, kelp and laver can be used to supplement fluorine. Generally, the fluorine content of animal foods is higher than that of plant foods, while that of marine animals is higher than that of fresh water and land foods.

Dietary fiber mentioned earlier is a kind of polysaccharide, which can not be digested and absorbed by gastrointestinal tract and can not produce energy carbohydrates.

Among them, soluble dietary fiber includes pectin, alginate, konjac, etc., and the main component is glucomannan, which has the outstanding characteristics of strong water absorption. The gastrointestinal tract is intertwined with other carbohydrates, delaying the absorption of the latter; Insoluble dietary fiber mostly comes from whole grains, beans, vegetables and fruits, which can promote gastrointestinal peristalsis, accelerate the passage of food through the gastrointestinal tract, reduce absorption, and absorb water in the large intestine to soften stools, thus playing a role in preventing and treating constipation.

Dietary fiber has a very important physiological function, and it is also closely related to improving and maintaining human immunity, anti-diarrhea and constipation, reducing intestinal polyps, diabetes, lowering blood cholesterol and triglycerides, controlling weight and colorectal cancer, and treating cholelithiasis and preventing and treating intestinal diverticulosis. Water-soluble dietary fiber swells after absorbing water, and chyme mass is sticky. Water-insoluble dietary fiber mixed with chyme mass can increase its volume, increase satiety and stimulate intestinal peristalsis. Bile acid secreted by the liver absorbs fat and cholesterol. Dietary fiber absorbs bile acids and reduces the absorption of cholesterol in food. Dietary fiber mixed with chyme can reduce the absorption of sugar in food by small intestine and reduce the metabolic burden of pancreas. Water-soluble dietary fiber is fermented by intestinal bacteria to synthesize short-chain fatty acids, breed probiotics and adjust intestinal PH value. Rapid defecation means that the stay time of feces in the intestine is shortened, and the contact between carcinogens and intestinal mucosa is prevented for a long time.

The standard of dietary fiber intake is 30g per day, while the dietary fiber intake of Chinese people is only 40% ~ 45%. The source of daily dietary fiber is based on the principle of food diversification, emphasizing the intake of soluble dietary fiber and taking into account the intake of insoluble dietary fiber. The content of insoluble dietary fiber in dark green vegetables is higher than that in light colored vegetables, such as leeks and celery. Bamboo shoots, wild vegetables. Potato food, nuts, mushrooms, fungus, kelp and other fungus food and apples, pears and peaches are rich in soluble dietary fiber.

The "price war" of the new car-making forces in February continued to heat up.

  Recently, a number of new car-making forces released delivery data in February. Affected by the Spring Festival holiday, the delivery of new car-making forces is generally less than that in January. Except for AITO and Ideal, the sales of other new car-making forces did not exceed 10,000 vehicles.

  With BYD and Tesla, two new energy head car companies, kicking off a new round of price reduction on March 1st, the "price war" in the Year of the Loong auto market continues to heat up, which may further accelerate the market reshuffle. According to the incomplete statistics of the "Securities Daily" reporter, since March, nine car companies have announced price reductions or opened limited-time concessions, with the highest price reduction of 47,000 yuan.

  "From an industrial perspective, the new energy vehicle market is shifting from incremental development to stock competition." Ou Yangming Gao, an academician of China Academy of Engineering, told the Securities Daily reporter that on the one hand, the new energy automobile industry itself is the survival of the fittest, and on the other hand, the game between new energy vehicles and fuel vehicles has reached a decisive stage, and the competition between independent brands and joint venture brands has also reached a white-hot level.

  AITO ranks first in the world of inquiry

  From the delivery data, AITO, Ideal and Ai ‘an are still stable in the first camp. In February, AITO delivered 21,100 new cars, a year-on-year increase of 503.20%, of which 18,479 new M7 cars were delivered, accounting for 87.4%. AITO ranks first among the new forces that have announced the delivery volume, surpassing LI again.

  It is noteworthy that the M9, the third model of AITO, officially launched the nationwide scale delivery on February 26th. According to official data, the M9 has exceeded 50,000 vehicles in 62 days. The increase of new products has become the next sales growth point of AITO.

  LI delivered a total of 20,251 new cars in February, up 21.8% year-on-year, and lost to AITO by a narrow margin. On March 1st, LI held the spring conference of 2024, and its first pure electric model MEGA and 2024 ideal L series models were officially launched. Li Xiang, Chairman and CEO of LI, said: "With the release and delivery of new models, our goal is to return to the level of monthly delivery of 50,000 vehicles in March." This means that the battle for the top spot in the delivery of new forces will continue.

  As the third runner-up in the list, GAC Ai ‘an sold 16,700 vehicles in February, down 44.57% year-on-year. Compared with AITO and Ideal in the first camp, the delivery of Guangzhou Automobile’s Ai ‘an has shown signs of fatigue.

  Except for AITO, Ideal and GAC’s Ai ‘an, the other new car-making forces and the "second generation" of traditional car companies have not maintained the previous trend of breaking 10,000 vehicles or hitting new highs, and the delivery volume in February was all below 10,000 vehicles.

  Specifically, the other car companies that have released the delivery volume in February are Weilai Automobile, Krypton Automobile, Zero Run Automobile, Nezha Automobile, Xpeng Motors Automobile and Lantu Automobile in order of delivery volume, with the delivery volume of 8,132, 7,510, 6,566, 6,085, 4,545 and 3,182 respectively, all of which showed a decline from the previous month, with a year-on-year change of-33 respectively.

  From the perspective of the whole industry, the new energy vehicle market was relatively sluggish in February, and the sales of new energy vehicles of traditional car companies such as BYD and Geely all showed a significant month-on-month decline. The Federation had previously predicted that the sales volume of the automobile market in February or the whole year was the lowest, and the domestic retail sales volume of narrow passenger cars was about 1.15 million, down 43.5% from the previous month, showing a regular seasonal trend; The domestic retail sales of new energy vehicles are expected to be 380,000, down 43% from the previous month, with a penetration rate of about 33%, and the market penetration rate has dropped significantly compared with the end of last year.

  Head car companies set off a "price war"

  It is worth noting that at the beginning of March, BYD and Tesla, two new energy car giants, set off a new round of "price war".

  Following BYD’s continuous launch of "Glory Edition" models in several market segments in February, on March 1, BYD once again shouted the slogan "Electricity is lower than oil" and launched the glory version of BYD Song Pro DM-i, with a starting price of 109,800 yuan. This also means that the A-class SUV model equipped with DM-i technology has officially entered the range of 100,000 yuan.

  Li Yunfei, general manager of Brand and Public Relations Department of BYD Group, said that thanks to BYD’s scale effect and the advantages of the whole industrial chain, the price of plug-in hybrid BYD can be lower than that of fuel vehicles of the same class. At the same time, Li Yunfei also said that this move will completely open a decisive battle with fuel vehicles. He even bluntly said, "Who will buy fuel vehicles next?"

  On the same day, Tesla followed closely and announced three benefits for Model 3 and Model Y models, including 8,000 yuan limited-time car insurance subsidy, 2,000 yuan limited-time car paint preferential price and limited-time car financial low interest.

  According to the reporter’s incomplete statistics, since then, car companies including Geely, SAIC Volkswagen, Feifan Automobile, Chery, etc. have successively announced price cuts and introduced preferential policies for limited-time car purchases. For example, Geely launched the Spring Car Festival in 2024, with a cash discount of up to 47,000 yuan during March; The TUANG family of SAIC Volkswagen started a limited-time discount, and at the same time, the 2.0T model can enjoy a cash voucher of 2,000 yuan or a three-year maintenance package; Feifan Automobile announced that its Feifan F7 model launched a limited-time car purchase policy, with a maximum discount of 30,000 yuan, and the advanced version, advanced Pro version, extended Pro version and performance Pro version were reduced by 25,000 yuan to 30,000 yuan.

  Guan Mingyu, global managing partner of McKinsey and head of McKinsey’s automobile consulting business in China, told the Securities Daily that the development of new energy automobile industry in China and even the whole world is at a crossroads, and the cost reduction brought by technological iteration will promote the popularization of new energy vehicles into the fast lane. "At present, the new energy vehicle market is evolving at an extremely fast speed. Only by catching up with technological changes and grasping consumer trends can car companies occupy more market share." (Reporter Gong Mengze)

Foreign teachers use generative artificial intelligence to assist teaching.

AI "ignites" the classroom

Foreign teachers use generative artificial intelligence to assist teaching.

  Generative artificial intelligence technology is more and more widely used in the field of global education. It can not only provide teachers with a variety of help such as generating personalized teaching plans and acting as classroom teaching assistants, but also provide students with interactive, collaborative, situational, inspiring and immediate learning experiences. With the change and improvement of technology, educators around the world adhere to the concept of technology for goodness and constantly explore the possibilities of applying generative artificial intelligence to classroom teaching. This issue of Global Weekly brings together some cases of foreign teachers applying generative artificial intelligence to improve the quality of classroom teaching, in order to provide new ideas for teachers to apply generative artificial intelligence creatively.

  English: Expanding Thinking and Promoting Deep Writing

  English writing ability includes not only superficial language elements such as vocabulary, grammar and discourse, but also deep literacy requirements such as pragmatic ability, cultural awareness and thinking quality. In the process of English learning, writing has always been a pain point and difficulty for students. Students often face writing obstacles such as insufficient vocabulary, vague grammar rules, lack of writing materials, and chaotic logical structure, which affects their enthusiasm for writing. Scientific writing training is very important.

  Stavros, a professor at Patrice University, introduced ChatGPT into senior high school English writing class, and tutored students’ English writing through ChatGPT. His English writing class is usually divided into three stages. In the first stage, students will write a theme composition in English, such as writing an email to a friend to introduce their favorite sports. At this stage, teachers will use ChatGPT to correct students’ vocabulary and grammar mistakes. In the second stage, students need to compare, analyze and learn the revised contents of ChatGPT, and at the same time, through discussion, reflect on whether the revised suggestions given by ChatGPT are reasonable, and sum up more correct and appropriate expressions. In the third stage, students will once again write a composition with a similar theme in English, and students can use the new expressions they learned in the previous stage in their second writing. By critically reflecting on the writing feedback given by ChatGPT, students acquire correct and appropriate pragmatic expressions in interaction, which promotes the development of cognitive ability and internalizes pragmatic knowledge and skills.

  Students’ fear of difficulties in English writing stems not only from the lack of English vocabulary and expressions, but also from the lack of logic and richness of views, which often leads to the trouble of not knowing what to write and how to write. In order to help students solve the problems of lack of writing materials, single writing point of view and confused writing ideas, Dr. Sidi Yulidar Harunasari of Indonesia introduced ChatGPT into his "Creativity and Media Writing" course. It is usually difficult for students to generate innovative writing ideas. Therefore, Sidi Yulidar Harunasari usually asks students to have a dialogue with ChatGPT in the first stage of the course, and students can choose their own interesting writing entry points in combination with the suggestions given by ChatGPT. Similarly, in the story structure, ChatGPT can also act as a virtual partner for students to help them build a complete narrative structure and a coherent story. On the one hand, students can send the synopsis of the story to ChatGPT for optimization, or seek advice by asking questions (for example, "Do you think the plot conflict setting in my story is reasonable?"). On the other hand, students can create stories with ChatGPT through dialogue. In the teaching process, teachers will supervise students’ use of ChatGPT to ensure that students use it as a tool for inspiration generation, rather than relying on it to directly create content. One form of supervision is to collect historical chat data between students and ChatGPT. By analyzing the chat data, teachers can further grasp the development of students’ pragmatic competence.

  Reading: Enriching Experience and Improving Literary Literacy

  Reading is the foundation of students’ academic success, and educators have been committed to helping students improve their reading ability. With the help of generative artificial intelligence technology, "Reading Coach" platform can provide learners with personalized, fascinating and revolutionary reading experience. Anna Ruiz, a fifth-grade teacher at Baldwin School in the United States, introduced this platform into her reading class and made full use of the different functions of "reading coach" to help students improve their reading ability and stimulate their reading interest. On the "reading coach", students can read textbooks, digital library texts or use artificial intelligence to generate stories. Anna Ruiz will let students use the "reading coach" to read the text independently, and correct the wrong words through the instant feedback tool on pronunciation and fluency provided by the platform. It is found that one of the most effective ways to help narrow the gap in reading ability is personalized learning. In the "AI story" mode of "reading coach", students can choose the protagonist, background and plot of the story, and the system will automatically generate a complete story that matches the reading level chosen by the learners. The sense of participation brought by story creation has greatly stimulated students’ love for reading.

  Reading famous books is also conducive to the improvement of reading ability, but how to make students deeply understand the characters and themes in famous books is often a difficult point for teachers to teach. Mike Kentz, an English teacher in a high school in Georgia, USA, uses the platform of Character.AI to help students understand literary works deeply in his English class. Character.AI platform is similar to ChatGPT, but the difference is that it allows users to chat with historical figures or celebrities, including famous scientists, literary heroes, movie stars, anime characters, etc. At the same time, the platform also supports users to build their own AI characters. After studying literary works, students may have doubts or construct some new ideas because they don’t have a deep understanding of people, events and themes. Mike Kentz found that his students were confused after learning The Catcher in the Rye, so he began to train students to use the Character.AI platform, arranged a classroom assignment to interview the virtual AI robot, the protagonist of the novel, Holden Kauffeld, and reminded students to actively listen to and respond to what the AI robot said. Students must compare the interview answers of AI robots with the actions, words and personality of the protagonist in the book to further deepen their understanding of the role. After the interview, the students will send the chat record with the AI robot to the teacher for class discussion. In the following discussion, each student should share the highlights and shortcomings of his interview and a deeper understanding of the characters. In this way, students jump out"Shallow reading" has realized a profound grasp of the reading content.

  History: creating situations and deeply perceiving history.

  The key to history teaching lies in breaking the gap between history and reality and narrowing the distance between students and history. By creating rich teaching situations, generative artificial intelligence leads students to perceive and discover history in an immersive way, and then helps students understand history and master historical knowledge.

  Benjamin Brin, a professor of history at the University of California, Santa Cruz, introduced ChatGPT as a teaching tool into the university history classroom, and simulated the interactive historical background in the classroom with the help of generative artificial intelligence to help students immerse themselves in learning history. Historical events are far from the present, and students are vague about the background of historical events, so it is difficult to really enter history in class. In order to help students fully understand the background and influence of the medieval plague, Benjamin Brin developed a "medieval plague simulator" based on ChatGPT. The simulator is available in three versions: Damascus, Paris and pistoia, with different protagonists and story lines. In the Damascus version, students play a traveler infected with the plague in Damascus. In the Paris version, students need to play a quack who profited from the plague by selling fake drugs. In pistoia’s version, the student plays an upright city councilman who is looking for a solution to the plague. Students enter the "simulator" through the shared document provided by the professor, and copy the prompts marked in the shared document into ChatGPT to enter the scene. For example, in the Damascus version, the professor set up prompts such as "health status", "doctor’s treatment", "confirm whether the family members are sick", "find a better doctor" and "restore health" and different scenes generated. In class, students first enter the "simulator" with the help of ChatGPT to experience stories and situations.Then the students compared their simulated experience with the real historical records of plagues in these three places, and wrote reflective papers. In this paper, students should further reflect on the authenticity, emphasis and representativeness of the simulated situation. Through this situational experience, students can think and explore historical events from multiple angles to deepen their understanding, and also cultivate critical thinking and creative thinking.

  The richness and interactivity of learning materials are very important for students to deepen their understanding of historical concepts. Professor Jussi of Turku University in Finland provides personalized learning materials for students of different levels through ChatGPT. He first determined the theme of the course and the corresponding historical data, and then used ChatGPT to generate text materials and test questions with three levels of difficulty: high, medium and low. In order to deepen students’ understanding, he used the AI painting software Midjourney to generate matching image data. In class, according to the students’ level, he personalized the learning materials of different difficulty levels and arranged the students’ learning content. Students understand what they have learned through text materials and picture materials, and then answer the test questions. After class, teachers use ChatGPT to check the completion of the test questions. If the students’ correct rate of the test questions meets the requirements, they will be assigned more difficult learning materials in the next stage of learning, otherwise the difficulty will be reduced. By providing students with personalized interactive learning materials, students’ learning participation and mastery of knowledge are significantly improved.

  Morality: Inspire thinking and deepen moral cognition.

  Moral courses usually emphasize guiding students to experience real situations, deepening students’ cognition and understanding of learning content, cultivating students’ deep thinking ability, and enabling students to enhance moral feelings and transform moral behavior in self-speculation and independent construction. Topic-based, situational and heuristic teaching methods are conducive to promoting students’ independent thinking and dialectical thinking, which are more common in moral courses.

  "Moral Dilemma" has become a common method to create situations in moral classroom because of its strong cognitive conflict. A primary school in Yamagata Prefecture, Japan, combines artificial intelligence with "moral dilemma" to stimulate students to think multi-dimensionally in the moral curriculum. Primary school students’ moral rationality needs to be formed and developed. Facing the specific life situation, primary school students’ understanding and comprehension of moral significance are often relatively simple, so teachers need to guide them effectively. Faced with the "moral dilemma", teachers set ChatGPT as one of the participants in class discussion. In the past, classroom discussion and communication were usually carried out among peers with similar cognitive level, but in the face of a new "smart partner", students need to think more deeply in order to promote the dialogue to continue. On the one hand, facing the answers provided by ChatGPT, students need to make new judgments and changes. Some students said, "I want to listen to AI’s judgment before making a decision", while others said, "I’ll think about it myself before asking AI". In the process of classroom discussion, teachers guide students to actively think and reflect on differences, and gradually form the ability to make independent judgments in the face of moral problems. On the other hand, there is no single standard answer to the "moral dilemma". The answers generated by ChatGPT can be used as topics for students to discuss and communicate, and students can further interact with ChatGPT to explore the causes of cognitive differences. By constructing the situation of "moral dilemma", teachers present the judgment of artificial intelligence, encourage students to think independently, reflect carefully and make decisions seriously, and finally enhance moral cognition.This unique learning experience increases the interest, participation and education of moral classroom.

  Generally speaking, generative artificial intelligence represented by ChatGPT has a wide range of application scenarios in the field of education, and teachers are constantly tapping the potential of generative artificial intelligence in classroom teaching, including human-computer collaboration, dynamic teaching framework, personalized learning support and counseling. However, there are still some uncertainties and some predictable and unpredictable risks in generative artificial intelligence. When using it in teaching, teachers should fully consider and avoid risks as much as possible, and pay more attention to cultivating students’ higher-order thinking, especially critical thinking and creative thinking. At the same time, teachers should constantly improve their digital literacy, constantly explore the use of new technologies, promote the integration of advanced technologies and classroom teaching, and make the classroom richer, more interesting and more efficient.

How "awesome" are those strategic scientists in China?

On the evening of September 28th, the headline of "News Network" for nearly 18 minutes released a heavy signal.
A thousand troops are easy to get, but a general is hard to find.
What does a strategic scientist mean to China? How "awesome" are the strategic scientists in China?
They are the best example—
Qian Xuesen is a pioneer and outstanding representative of China’s aerospace science and technology. He has made pioneering contributions in the fields of aerodynamics, aviation engineering, jet propulsion, engineering cybernetics, physical mechanics and other technical sciences. He is the founder and advocate of the theoretical and applied research of modern mechanics and systems engineering in China.
At the beginning of 1956, Qian Xuesen put forward "Opinions on Establishing China’s National Defense Aviation Industry" to the Central Committee of the Communist Party of China and the State Council. In the same year, Qian Xuesen was appointed to set up the first rocket and missile research institution in China.
Qian Xuesen presided over the establishment of jet and rocket technology, participated in the development of short-range missiles, medium-short-range missiles and China’s first man-made earth satellite, directly led the "two-bomb combination" test of carrying atomic bombs with medium-short-range missiles, participated in the "two-bomb combination" test of carrying atomic bombs with short-range missiles in China, participated in the development plan of China’s first interstellar aviation, and developed and established disciplines such as engineering cybernetics and systematics in China …
Under the leadership of Qian Xuesen, the first atomic bomb exploded successfully in China on October 16th, 1964, the first hydrogen bomb exploded successfully in China on June 17th, 1967, and China’s first artificial satellite was launched successfully on April 24th, 1970.
Li Siguang is the pioneer and founder of modern geology in China, and has made great contributions to China’s geology, oil exploration and construction.
Li Siguang has discovered a large number of relics in Taihang Mountain, Jiuhua Mountain, Tianmu Mountain, Lushan Mountain, Huangshan Mountain, Yangtze River Basin and other places, and refuted the wrong conclusion of foreigners that there is no Quaternary glacier in China with scientific facts.
Li Siguang founded geomechanics, studied the phenomenon of crustal movement from the viewpoint of mechanics, explored the laws of geological movement and mineral distribution, and the characteristics of the new Cathaysian tectonic system, and analyzed the geological conditions in China, which proved that there must be oil on the land of China, theoretically overturned the conclusion that China was poor in oil, and affirmed that China had good oil storage conditions. In 1956, he personally presided over the oil survey and exploration. In a short time, he successively discovered Daqing, Shengli, Dagang, North China, Jianghan and other oil fields, which made an indelible contribution to China’s efforts to get rid of the "poor oil" hat.
Huang Danian, a famous geophysicist, has made a series of important scientific and technological achievements in the field of aviation geophysics, filled many domestic technical gaps and made outstanding contributions to the exploration of deep resources and the construction of national defense security in China.
"As long as the country needs it, I will do it! There is nothing to say. "
After returning to China for seven years, Huang Danian led his team to break through various technical difficulties. In the project of aviation mobile platform detection technology and equipment, it took five years to complete the journey that western developed countries have traveled for more than 20 years. In the research and development of sophisticated gravity gradiometer, the speed of research and development in China has been shortened by at least 10 years compared with that in the world in terms of data acquisition ability and accuracy, while the algorithm has reached the international level.
More than four years after Huang Danian’s death, according to the strategic plan designed before his death, the team of Huang Danian has never forgotten his mission and worked hard to complete its unfinished business: around the national strategic plan of deep sea, deep space and deep ground, the team of mobile platform exploration center has carried out key research and development in many directions, such as the development of intelligent heavy-load geophysical special UAV platform, the development of airborne gravity gradiometer and the development of integrated geophysical data software platform for mobile platform, and achieved gratifying phased results.
Yuan Longping is a pioneer in the research and development of hybrid rice in China. He devoted his life to the research, application and popularization of hybrid rice technology, invented the "three-line method" indica hybrid rice, successfully studied the "two-line method" hybrid rice, and created the super hybrid rice technology system, which made outstanding contributions to China’s food security, agricultural scientific development and world food supply, and was known as the "father of hybrid rice".
In 1966, Yuan Longping published the paper "Male Infertility of Rice", which started the research of hybrid rice in China. In 1970, he discovered a wild rice with pollen abortion in Hainan, which opened a breakthrough in hybrid rice research.
In 1986, Yuan Longping formally put forward the strategy of hybrid rice breeding: from three-line method to two-line method, and then to one-line method, that is, the procedure developed from complex to simple but more efficient. After years of hard work, the two-line method was successful, which ensured China’s leading position in the field of hybrid rice research.
In April, 1979, at the International Symposium on Hybrid Rice, Yuan Longping read his paper "Hybrid Rice Breeding in China", and China passed on the successful experience of hybrid rice research to the world for the first time.
Since 1980s, Yuan Longping and his team have trained more than 14,000 technical talents of hybrid rice for nearly 80 developing countries through the international class of hybrid rice technical training. At present, more than 40 countries and regions around the world have achieved large-scale planting of hybrid rice, and constantly created high-yield records in the local area. The annual planting area of global hybrid rice reaches 7 million hectares, which is generally more than 20% higher than that of local rice.
On September 5th, 2021, the second-generation hybrid rice "Chaoyouqian" began on-site yield measurement and acceptance in Mengzi Demonstration Base of Yuan Longping Super Hybrid Rice, located in Caoba Town, mengzi city, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province. The final yield measurement result was 1107.5 kg per mu, and the average yield per mu of 100 mu was over 1100 kg for four consecutive years.
Sun Jiadong is one of the pioneers in China’s artificial satellite technology and deep space exploration technology. As the chief designer of the first phase of lunar exploration project, he has made outstanding contributions to China’s breakthrough in basic satellite technology, satellite return technology, geostationary orbit satellite launch and fixed-point technology, navigation satellite networking technology and deep space exploration technology.
Sun Jiadong is the technical director and chief designer of China’s first missile, the first artificial earth satellite, the first remote sensing exploration satellite and the first recoverable satellite, and the chief engineer of the second generation application satellites such as China communication satellite, meteorological satellite, resource exploration satellite and Beidou navigation satellite.
From studying aircraft design, developing missile weapons and starting a satellite business, Sun Jiadong closely linked his personal ideal with the destiny of the motherland, devoted himself to the space army with the ambition of "I will do it if the country needs it", and always took the space industry as a stage to serve the motherland. He particularly emphasized the need to persist in independent innovation: "When we are poor and white, we have no experts to rely on and no technology to learn from, so we can only rely on ourselves and innovate independently. Today’s young people engaged in aerospace must have the concept of independent innovation and master the right to speak of core technologies. "
Liu Yongtan, the founder of China’s new maritime radar system, has been devoted to the research of the new maritime radar system for nearly 40 years, which has filled the gap in this field in China and made the monitoring area of China sea area from less than 20% to full coverage.
Since 1980s, Liu Yongtan has insisted on independent research and development of new radar system, led the team to break the monopoly of foreign technology, and created a "golden eye" for the radar in the coastal areas of the motherland.
In 1989, the new radar experimental system was completed, and it took Chinese eight years to catch up with the western countries for twenty or thirty years.
In 2011, a new system radar with all-weather, all-weather and long-distance detection capability was successfully developed and put into practical application, which conquered the core technology in the international leading position. China has also become one of the few countries with this technology in the world.
Facing the country’s future offshore strategic needs, Liu Yongtan, an octogenarian, is still active in the front line of scientific research, continuing to lead the team in planning and implementing systematic research on offshore remote detection, and gradually developing independent innovations in distributed and miniaturized forward-looking technologies.
…………
Science knows no borders, but scientists have their motherland. Strategic scientists are not only the precious wealth of national development, but also the individual presentation of the country’s comprehensive strength. They are the "heavy weapon of the country" and are indispensable and irreplaceable.
"Adhere to the long-term vision, consciously discover and cultivate more high-level compound talents with the potential of strategic scientists, and form a growth echelon of strategic scientists."
The journey is long, only struggle.
