　　Recently, the 18th issue of Qiushi magazine published the important article "Unswervingly Upholding and Strengthening the Party’s Overall Leadership" by the Supreme Leader General Secretary. The article points out that the Party is the core of leadership in all our undertakings. As the ancients said, "Six rivers share the same wind and Kyushu share the same experience", in contemporary China, this cannot be done without the leadership of the Party. History and reality show us that the party’s organizational line serves the party’s political line, and upholding and perfecting the party’s leadership is the fundamental purpose, value orientation and important principle of organizational construction. To do a good job in the Party’s organizational work in the new era, we must implement the Party’s leadership in all aspects of organizational work, arm our minds, consolidate our branches, organize party member, unite talents, mobilize the masses, and boost our work style, so as to provide a strong organizational guarantee for promoting the cause of Socialism with Chinese characteristics in the new era.

　　Firmly grasp the "primary task" of political construction.Our party has always attached great importance to political party building. From "all work belongs to the branch" to "the branch is built on the company"; From "upholding the party’s political leadership over state-owned enterprises" to "implementing the principal responsibility system under the leadership of party committees in colleges and universities", party organizations at all levels have always put the anchoring of political direction, strengthening political construction and giving full play to political functions on the top, in order to achieve the party’s political program, objectives and mission. The history of the party’s history in the past century has eloquently proved that from the little red boat to the mighty ship, from the road to the revival, when the party’s political line and organizational line are well adhered to, when the party’s organization will flourish and the party’s cause will advance smoothly. Party organizations at all levels and cadres in party member should consciously check the standard and correct the deviation in time, always be consistent with the Party Central Committee’s thinking, goals and actions, ensure the smooth implementation of government decrees and prohibitions, earnestly enhance the "four consciousnesses", strengthen the "four self-confidences" and achieve the "two maintenance". It is necessary to be serious about the political life within the party, take party constitution’s party rules and normative documents as the general basis, and adhere to democratic centralism and "three meetings and one lesson"System, democratic life meeting system, organizational life meeting system, heart-to-heart talk system, democratic appraisal of party member system, request for instructions and reporting system, etc., and constantly enhance the political leadership of party organizations.

　　Always do a good job in the "casting soul project" of theoretical armed forces.If you want to do something, you must first do it. Attaching importance to ideological and political education is a fine tradition and political advantage of our party. For Party organizations at all levels and cadres in party member, every step forward in theoretical innovation will be followed by theoretical armed forces. The Sixth National Congress of the Communist Party of China held in June 1928 made it clear that the most important task of the Party branch was to "encourage and publicize communism" and "make workers and peasants stand on the side of the Party". Since the 18th National Congress of the Communist Party of China, our party has successively carried out the mass line education practice activities, the special education of "three strictness and three realities", the study and education of "two studies and one doing", the theme education of "Do not forget your initiative mind, bearing in mind the mission" and the study and education of party history, all of which started with the word "learning" and took a deep understanding of the supreme leader’s Socialism with Chinese characteristics Thought in the new era as the main line of education. Practice has proved that to strengthen organizational construction, it is necessary not only to "shape and strengthen the body", but also to "tamp the foundation and cast the soul", and vigorously promote the ideological party building and strengthen the party with theory. Party organizations at all levels and cadres in party member should vigorously promote the trend of "lifelong learning", adhere to the principle of "thought leading, learning first", learn from the original, systematically and comprehensively, think deeply, integrate knowledge with practice, and promote the combination of concentrated learning and regular learning.Deeply understand the scientific nature of Marxism in contemporary China and the 21st century, the people’s standpoint, the openness of the system and the practicality of the character, and make up the "spiritual calcium" that is determined to move forward in the new journey of building a socialist modern country in an all-round way.

　　Constantly consolidate the "four beams and eight pillars" of the institutional system.If the moment is not right, it cannot be square; If the rules are not correct, they cannot be round. The party’s system construction is a powerful guarantee for the party’s organizational construction. It has been revised for 17 times since the Second National Congress of the Communist Party of China formulated the first party constitution. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee has vigorously promoted the construction of institutional system, and promulgated Regulations on the Work of the Communist Party of China (CPC) Branch, Regulations on the Work of the Communist Party of China (CPC) Group, Regulations on the Election of Grassroots Organizations in the Communist Party of China (CPC), Regulations on the Work of the Communist Party of China (CPC), etc., which have formed the "1+4" basic framework of party constitution, organizational regulations, leadership regulations, self-construction regulations and supervision and guarantee regulations, and the "four beams and eight pillars" of the party’s institutional system have been improved day by day. In view of the fundamental, long-term and stable organizational system of the Party, party organizations at all levels and cadres in party member should, on the one hand, strengthen systematic thinking, sum up grass-roots initiatives in time, improve the scientific, standardized and rigorous institutional innovation, and promote the formation of a well-organized and powerful organizational system with a perfect institutional system to ensure that the party’s leadership is "like an arm, like an armband"; On the other hand, it is necessary to strengthen the bottom line thinking, clarify the red line of the bottom line, strictly abide by the party’s political rules and disciplines, put an end to "seven haves", achieve "five never allow" and "five musts", not only make good use of the "four forms" of supervision and discipline, but also resolutely implement "three distinctions".Fully mobilize the subjective initiative of the officer to start a business.

　　Make full use of the "winning magic weapon" of the mass line.The party’s mass line is not only our party’s fundamental political line, but also our party’s fundamental organizational line. Over the past hundred years, our party has been able to overcome all difficulties and obstacles, break through all blockades, and overcome all risk challenges because it has always insisted on writing "people first" into its purpose, printing it on its banner, blending into its veins, and falling into action. The word "people" has always been the starting point, main line and destination of the party’s idea of governing the country. After eight years of fighting against poverty, the party organizations of 22 provinces (autonomous regions and municipalities) signed a "military order" with the central authorities, and selected more than 3 million first secretaries and village cadres from organs at or above the county level and state-owned enterprises and institutions, and fought side by side with nearly 2 million township cadres and millions of village cadres. Bright red party flag fluttered high in the main battlefield of fighting against poverty. Party organizations at all levels and party member cadres should follow the mass line in the new era, persist in coming from the masses to the masses, pay close attention to the people’s urgent difficulties and worries with the excellent style of being ordered by the DPRK, drinking ice at night, doing nothing at night, and do it resolutely, immediately if it can be done, and difficultly, so as to serve the people well with the attitude of rushing ahead, the mentality of catching up with exams and the state of catching up with others, and polish the "party flag Red" even more.Sharp heart.

　　Xinhua News Agency, Jinan, August 7th, New Media Specialist (Reporter Wang Yang, Zhang Yujie) Recently, dog abuse and killing incidents have been exposed in Weihai, Dongguan, Lianyungang and other places one after another. The related videos and pictures are cruel and savage, and both online and offline have aroused public dissatisfaction and heated discussion. Some netizens think that it is inappropriate to kill animals and be sentenced to damage property or undermine public security. Some netizens said that it is worrying that some people have no scruples about treating small animals.

　　Frequent incidents of dog cruelty have aroused public anger, and what kind of punishment should be faced with such animal cruelty has aroused social discussion. The reporter interviewed relevant experts, lawyers and animal protection agencies on issues of concern to netizens.

　　According to media reports, a citizen of Weihai, Shandong Province recently towed a pet dog with an off-road vehicle on the highway, causing some people to contain it. Related videos were circulated on the Internet.

　　Coincidentally. According to netizens, a man living in Dongguan adopted more than 50 stray dogs and killed them for fun. According to a recent posting by a netizen in Lianyungang, a local woman was bitten by a big dog in a residential area when she came home with her boyfriend. Later, the woman’s boyfriend met the biting big dog again in the residential area and injured the dog. After that, the dog owner reported to the police that the dog had been killed.

　　Lawyer Yang Shaogang, director of Shanghai Shaogang Law Firm, said that many recent incidents of dog abuse have aroused the indignation of the masses, but such cases are not individual cases, and some animal cruelty is more serious and cruel. For example: burning cats with fire, stepping on cats with high heels, beating dogs with sticks, and entertaining some mentally distorted people with various strange methods of cruelty to animals, but no cases of punishment have been seen. Because the law does not stipulate the punishment for cruelty to animals.

　　Lawyer Yang Shaogang said that the incident in Shandong is slightly different from the general dog abuse. Because the owner of the car paraded through the street in front of the public, the people saw the animals being abused alive and died tragically, which caused compassion, so the onlookers and human flesh search were completely understandable. I think the public security organs can completely detain them for more than five days and less than ten days in accordance with Article 23 of the Law on Public Security Administration Punishment, and impose a fine of less than 500 yuan.

　　The staff of China Small Animal Protection Association told the reporter that at present, China only has the Wildlife Protection Law of People’s Republic of China (PRC), but there is no relevant legislation for the protection of pets and domestic animals, which is not conducive to the protection of non-wild animals.

　　The staff said that the recent incidents of cruelty to animals have had a very bad impact, which touched the bottom line of the people. However, without the protection of relevant laws, these abusers would only suffer moral condemnation at most, which is not enough to deter these abusers. They may also abuse animals again, hoping to introduce a comprehensive animal protection law as soon as possible.

　　According to legal experts, there is no law against "cruelty to animals" in China except People’s Republic of China (PRC) Wildlife Protection Law, Regulations on the Management of Laboratory Animals, Regulations on the Management of Medical Laboratory Animals, Regulations on the Protection of Aquatic Wildlife and Regulations on the Protection of Terrestrial Animals. Article 29 of the Regulations on the Administration of Medical Laboratory Animals states: "The staff engaged in laboratory animals must take good care of them and shall not tease or abuse them." Article 31 stipulates: "According to the seriousness of the case, warning, improvement within a time limit or administrative sanctions shall be given respectively." This is for experimental animals, and there are no prohibitive regulations for general animals.

　　Lawyers such as Yang Shaogang told reporters that since 2005, there have been many incidents of animal cruelty in China, and some people have called for legislation to protect animals. However, there are two different opinions, and the opposition to legislation has prevailed. Therefore, there has been no legislation on animal protection in China for a long time, but the legislation on wild animals has not only been enacted by the National People’s Congress, but also by many places. Its legislative purpose is not to consider animals as human friends, but as human resources, in order to prevent the loss or plunder of resources.

　　According to incomplete statistics, more than 100 countries and regions have enacted the Law on the Prohibition of Cruelty to Animals, and the maximum penalty for cruelty to animals is imprisonment for less than five years. Britain, the United States, Japan, Italy, Germany, Canada and other countries have formulated the Animal Protection Law, the Animal Welfare Law and the Standards for Medical Laboratory Animals, which have made strict regulations on the protection of animals. Even if pets are lost, their owners will be punished, which shows that they attach importance to animal protection.

　　Experts believe that the publication and publicity of animal cruelty, calling for everyone’s attention and condemnation, is itself the progress of animal protection awareness.

　　Cao Han ‘ai, an expert in animal law at Griffith University in Australia, told the reporter, "Five or six years ago, I assisted legal scholars in drafting the Animal Protection Law of People’s Republic of China (PRC) (expert’s suggestion draft). At that time, the law against animal cruelty was too advanced in China and was not suitable for the national conditions at that time. But in recent years alone, China has made great progress, which is the progress of China society. "

　　She introduced that at present, more and more animal activists and ordinary people in China, especially young people, have contributed their money to help all kinds of animals voluntarily, to condemn and stop abuses, to report illegal trafficking and hunting of wildlife under state protection, and so on. "All these show that people’s awareness of animal protection far exceeds the current legal provisions."

　　People’s Daily Online, Beijing, August 4 (reporter Li Yan) action giant "Dangerous City" will be released nationwide on August 12, powerful actor Liu Qingyun as the head of the defense team Yang Kenan, after many years of shooting drama Liu Qingyun spent three months practicing the whip, a word does not "whip" himself, the arm will draw out the whip marks, Liu Qingyun also considered himself the most "dangerous" character on the set, but also many times to apologize: "whip is difficult to master, accidentally will hit other people, I’m really sorry". Action director Hong Jinbao was full of praise for him, whip into 180 degrees of action in just three days. Today, the film exposed the poster of Liu Qingyun’s character in the "Murderous City" series. Liu Qingyun wields the whip with ease, and at the same time highlights the loyalty and responsibility of the characters, which can be called the "central idea" of the film. In addition, Liu Qingyun and Gu Tianle, who were nicknamed "Qingtian" CP by netizens, staged a wonderful showdown against each other.

　　The harder you practice the whip, the more you get addicted, and you get praise for being handy. "You can hit wherever you want"

　　In the poster of Liu Qingyun’s character exposed this time, under the red and black ink brushstrokes, Liu Qingyun held a two-meter long whip and was full of blood and righteousness. The weapon setting of the long whip was also tailor-made for Liu Qingyun by the action director Hong Jinbao, "Because to create a dashing image, whether it is close combat or open distance, the long whip weapon is very suitable for Liu Qingyun’s role." This time in "Dangerous City", not only did Liu Qingyun challenge the play after many years, but he also told the director Chen Musheng earlier, "I haven’t filmed a play for a long time, can you rest assured to find me?", but when he learned that Hong Jinbao was the action director, he put down his doubts. This was also the first collaboration between Liu Qingyun and Hong Jinbao. With the guidance of the action director Hong Jinbao, Liu Qingyun waved a long whip extremely wonderfully, "Brother Hong is really experienced. He will tell me some small skills, and he can easily master the essentials."

　　However, Liu Qingyun has also been injured many times during the filming of the fight, and if he is not careful, the whip in his hand will draw himself, "In fact, it is just injured while shooting, because it is really difficult to hit the whip to 180 degrees, and after each shooting, I have a strip of whip marks on my hands." For this reason, Liu Qingyun also practiced while shooting, and in just three days, he mastered the skill of shaking the whip to 180 degrees, which was praised by director Chen Musheng. "Liu Qingyun practiced very well. It can be said that he is very handy with the whip, and he can hit wherever he points." Action director Hong Jinbao also said that Liu Qingyun’s practice made the shooting more effective with half the effort. When it comes to the experience of filming the play, Liu Qingyun seems to be still unsatisfied, "I really enjoyed the experience of filming the play, and I felt like a child who came to the playground. Everything I felt was very fresh, and the more I played, the more addicted I became."

　　"Qingtian" CP staged the ultimate showdown against each other, and Liu Qingyun interpreted the toughness and chivalry

　　It is well known that Liu Qingyun and Gu Tianle are old partners for many years, and the tacit understanding between the play and the play is full. In the personal trailer exposed this time, Liu Qingyun and Gu Tianle have staged duel scenes many times, and they will go to war if they don’t agree with each other. In "Dangerous City", Liu Qingyun plays Yang Kenan, the head of the Pucheng Defense Team, who is responsible for guarding the safety of the entire Pucheng people during the extraordinary period of warlords’ war. In the film, Gu Tianle plays Young Marshal, a warlord who is willful, bullying, and happy to kill. After Gu Tianle’s forces invade Pucheng, they start a duel between justice and evil. For the character in the film, Liu Qingyun praised "he is really tough," and the director Chen Musheng said that he is a true hero. "Liu Qingyun’s role this time is the central idea of the whole film. He is the most persistent one. When everyone gave up, he still insisted on facing the power, and even sacrificed himself to face the most sinister bad guys."

　　The movie "Dangerous City" starring Liu Qingyun, Gu Tianle, Peng Yuyan, Yuan Quan, Jiang Shuying, Wu Jing special performance, Liao Qizhi, Shi Yanneng, Wu Tingye, Hong Tianzhao, Jiang Haowen co-starring, the film will be released on August 12.

　　On January 11th, China Automobile Industry Association announced that in 2023, China’s automobile production and sales both exceeded 30 million vehicles for the first time, setting a record high, among which China’s automobile exports reached 4.91 million vehicles, which is expected to become the first automobile exporter in the world.

　　The position of the world’s first automobile exporter, the United States, Germany and Japan.Have been sitting.. This is the change chart of automobile export volume of three countries in recent years.

　　Among them,China new energy automobileIt is an important driving force for China’s automobile export. However, some voices think that this achievement is the ceiling of new energy vehicles in China.

　　In fact, in recent days, such a "cold water" voice is not uncommon.

　　To answer this question, we need to look at how China’s new energy vehicles opened up the export situation.

　　Looking back at this rising curve, we can find that the turning point occurred inIn 2021In that year, China exported new energy vehicles.Year-on-year growth of 3 times.

　　At that time, many foreign media mentioned a background when analyzing this data — —Global manufacturing supply chain is difficult to operate.. Compared with 2019, the global automobile production in 2021 is overall.Down 13%.

　　When others can’t produce, China can, and when others can produce, China is relatively cheap. In the eyes of many people, this is the "password" for China’s new energy vehicles to successfully go to sea.

　　This is also the reason why some people think that China’s new energy vehicles hit the ceiling — — Since China’s supply chain is already very complete, what it can provide.There are limits to the cost advantage.As global manufacturers of new energy vehicles are reducing costs, once the cost advantage of China is no longer obvious, it seems that China new energy vehicles can only fall into.Vicious competition of "price war"Medium.

　　Is this really the case?

　　When analyzing the export data of new energy vehicles in China, we also found such changes:

　　In 2019, the average export price of new energy vehicles in China was5000 USD/vehicleIt rose to 2022.22,000 USD/vehicle.

　　In other words, in recent years, China’s new energy vehicles have really come true."quantity and price rise together".

　　The price is high, and there are sales. Overseas markets accept the pricing of new energy vehicles in China, which fully shows that the more fundamental reason for China’s new energy vehicles to open up in the global market lies in.Product force.

　　Where does this product strength advantage come from?

　　Master Tan saw such a set of data:

　　Research shows that from 2018 to 2022, the average cruising range of pure electric vehicles in the world.Jump from 230 km to 337 km.

　　Endurance has always been a big problem that restricts the development of new energy vehicles. There is a word in the automobile industry called"mileage anxiety"That is, consumers are worried that the battery life of new energy vehicles cannot meet their own needs.

　　So, what is the average cruising range of new energy vehicles in China in 2022? According to the relevant data of the Chinese Academy of Sciences, this figureClose to 600 kilometers.

　　Not only that, according to the industry’s evaluation, the cruising range of 1,000 kilometers is the real turning point for the use experience of new energy vehicles to equalize fuel vehicles. Now, the cruising range of 1,000 kilometers has become the "standard" for many new energy vehicle enterprises in China.

　　It will not be easy.

　　One factor that affects battery life is battery capacity. It seems that as long as the battery capacity is continuously increased, there will be a breakthrough in battery life, but in fact, this is not the case. Battery capacity, safety and durability are like a seesaw. If one of them is pursued excessively, the others will decline.

　　How does the seemingly contradictory problem, China, give a solution?

　　Tan Lord noticed such a data:

　　Among the top ten companies in the world with installed power batteries,China enterprises occupy 6 seats..

　　Cui Dongshu, secretary-general of the Association, who has been in the automobile industry for more than 30 years, told Tan Zhu that there are many breakthroughs in the industry in improving the performance of batteries, and there are still many nodes in the key technology chain such as anode and cathode materials, electrolytes, separators and membrane electrodes.Performance improvementSpace.

　　For example, in order to further extend the batteryEnergy density and safety,There are many solid, sodium ion, high nickel and aluminum air in the industry.New technical route.

　　In fact, the competitiveness of new energy vehicles in China comes from the fact that the whole industry has entered.differentiationcompeteIn the orbit, everyone’s pursuit of battery life is essentially to study power batteries with larger capacity, smaller volume and higher energy density from different aspects, as well as electronic control technology with better energy consumption, and then to break through the bottleneck of power battery technology.

　　Such a breakthrough is not only reflected in the cruising range.

　　China’s new energy vehicles are a new growth point of China’s automobile export. While the scale is increasing, it is necessary to constantly rely on innovative development models to eliminate the risks brought by the continuous improvement of production capacity.

　　China’s new energy automobile industry has chosen a different path.

　　Generally speaking, a fuel truck has about30,000Parts, these parts, together with supporting chips and software, constitute a function of the car body. The parts and chips of each function are relatively independent, which leads to the more functions of a fuel truck, the more subsystems are needed. Because the systems are not connected, this leads to the system of the fuel truck."bloated".

　　Click to view the panorama of automobile industry chain.

　　This feature also limits the improvement of the function of fuel vehicles.

　　But the parts of new energy vehicles can be less than half of those of fuel vehicles. This means that compared with fuel vehicles, new energy vehicles have higherPower supply capacityWith higherElectrification degreeIt is naturally available.The foundation of intelligence.

　　More importantly, the era of the development of new energy vehicles is alsoThe era of vigorous development of mobile internet and information technology. There is a saying in China’s new energy automobile industry — — Intelligent new energy vehicle is to install four wheels on the mobile phone.

　　This sentence shows that in China, Internet thinking and the automobile industry are merging, and this superposition is also rewriting the logic of automobile production:

　　Many electronic control units of traditional fuel vehicles are integrated into a few power, body, autopilot and cockpit in new energy vehicles.Several systemsAmong them, and after these systems, there is a unified perception and management of vehicle status.Central computing center.

　　Under such circumstances, the software and hardware of new energy vehicles have achieved close cooperation. For example, the hottest autopilot function at the moment is to rely on sensors and chips carried by vehicles first.Hardware collects information, let againsoftwareAnalyze the surrounding road conditions, and finally hand over the instructions issued by the software to.Vehicle power system executionThe whole process does not require the driver to participate too much.

　　More importantly, while the vehicle itself is a system, the massive data generated by other car owners during driving can also be passed.Big data, cloud computingAnd other technologies, throughRemote download and upgradeThe way to interact and upgrade with specific vehicles.

　　It is no exaggeration to say that in the new energy era, cars have changed from those that originally needed human manual manipulation.Pure mechanical products, evolved toIntelligent products controlled by algorithms and data.

　　Such a change is not available in every country. Among them, the transformation of European car companies is more difficult. An analysis of the automobile industry mentioned that:

　　Why China and the United States have gone further than other countries in the intelligentization of new energy vehicles, a large part of the reason is that China and the United States have taken the lead in the wave of mobile Internet. If car companies in Europe and Japan understand the intelligence of cars as electrification, then China and the United States understand the intelligence of cars as"Automobileization of Smartphones".

　　It is precisely because of the relationship with information technology industries such as the Internet.superiorityCarried outSuperimposed integration,The intelligentization of new energy vehicles in China has created new scenes and demands for consumers. If we say that in the era of fuel engine, the possibility of automobile is aggregated in parts, then the automobile in the intelligent era, data and computing power can be extended and created, which will be unimaginable space.

　　Click on the export amount of new energy vehicles in China on the following picture, and you can find that behind the accelerating growth, a very important part of the reason is the continuous creation of intelligence.New performance, inspired consumers.demand, thus driving the production capacityConstantly expanding.

Click on the spot above to see more information.

　　At present, European car companies are increasingly turning to China enterprises.buyPure electric modular platform and pure electric production line are used toexploitationYour own new energy vehicle. Standing on the platform built by the development of new energy vehicles in China, European car companies, which have advantages in the traditional car-making field, can complete the turn faster.

　　This also shows a trend:

　　Intelligence is being paid more and more attention by automobile manufacturers. With the transformation of global economy to digital and low carbon, the market faced by new energy automobile industry is still a deep blue ocean. And China,Has taken the lead.

　　In fact, whether it is intelligent or a breakthrough in cruising range, it is a microcosm of the development of new energy vehicles in China. What it represents isSystematic thinking— — existNew energy automobile industry chainAt every node, China has a number of pioneering technological explorations and breakthroughs to expand the depth of industry development.

　　The three-dimensional development trend constructed by these technological breakthroughs constitutes the extensibility of the industrial chain and supply chain, and this extensibility is also the depth of absorbing and integrating production capacity, and it also brings more room for handling some problems.

　　From this point of view, compared with the number of automobile exports in China, the unique development model we have explored in this process can not be ignored.

The Mid-Autumn Festival and National Day are "two festivals in one", and the Asian Games boom is superimposed. The tourism popularity of the "Eleventh" holiday has been rising all the way, and it is expected to usher in the most prosperous "Golden Week" in five years. Go to Ningbo to eat seafood, go to Ningxia to eat beach mutton, and go to Suzhou to eat hairy crabs … Around the Mid-Autumn Festival, the must-eat food in various places is hot and new, and the holiday "Taste Bud Tour" is continuing to become popular. Recently, the reporter learned from relevant platforms that as of September 20th, the number of food reservations in national dining halls increased by 112% compared with 2019.

The "Eleventh" holiday is approaching, and the catering service consumer market is busy again. Faced with the obvious recovery of consumption, many restaurants posted "recruitment notices" half a month ago, and planned ahead for "Golden September and Silver 10" through the online platform for the new autumn package and the live pre-sale.

In order to grasp the consumption peak of this super-long Golden Week and do a good job in the second half of the year, Chengdu Houtang Hot Pot began to recruit workers two weeks in advance. Compared with September, stores should recruit about 40% more part-time jobs during the National Day. 31 stores in Quanwuhan, Feifei Shrimp Farm have also started recruitment plans. Each store in popular tourism and business districts needs to recruit about 20 part-time jobs, which is twice as many as last year. At the end of August, Haidilao, a national chain, began to recruit people to reserve for the National Day. A manager of Haidilao said that he didn’t recruit any more employees during the May Day, but he made preparations in advance for the Eleventh Day and added six part-time employees during the holiday. "It is expected that the passenger flow in the Eleventh Day will be larger than that in the May Day, and there will be more family gatherings."

Zhu Jie, director of the operation of Jipin Xiaoxian, a must-eat restaurant in Shanghai, said that since the beginning of the month, customers have successively booked Mid-Autumn Festival packages through online platforms. At present, the booking rate of Mid-Autumn Festival has exceeded 80%. Feifei Shrimp Restaurant, a must-eat restaurant located on the pedestrian street of Jianghan Road in Wuhan, is expected to queue for three or four hours during the National Day, and the restaurant is making efforts to recruit more part-time employees.

Behind the new and early recruitment, it reflects that catering businesses have expectations for boosting consumption. In the first eight months of this year, the national catering revenue increased by 19.4% year-on-year, and catering has become a powerful representative of the booming service retail. In order to further enhance consumer confidence.

The reporter learned from the US Mission and public comments that the number of online reservations for restaurants nationwide increased by 112% compared with the same period in 2019. Compared with the same period of last year, the order volume of Mid-Autumn Festival "Reunion" theme group purchase package increased by over 90%, and the "Reunion Meals" in Shanghai, Beijing, Hangzhou, Nanjing and Tianjin were the most popular.

It is worth mentioning that many catering businesses have also made great efforts in menu and online operation this year. At present, it is the golden autumn season, and fruits, vegetables and catches have a bumper harvest. Fat Portunus crab in Zhoushan, Zhejiang, hairy crab in Yangcheng Lake, osmanthus fragrans in Manjuelong, Hangzhou … More and more seasonal ingredients are on the table all over the country.

The data shows that in the last week, the number of restaurants bought by Shangxin "Hairy Crab" and "Portunus Crab" increased by 140% compared with the same period of last year, and related orders increased by 260%; The number of food and beverage outlets that launched "Osmanthus fragrans" group purchase new products increased by 112%, and Osmanthus fragrans fermented milk tea, Osmanthus fragrans latte and Osmanthus Jelly were all hot-selling items.

On the eve of Mid-Autumn Festival and National Day, more than 20,000 catering merchants across the country moved moon cakes and hairy crabs to online through the US Mission. Many of them also launched live broadcast and group purchase and distribution capabilities, allowing users to enjoy special group purchases at the store and choose to deliver them home.

On September 25th, Yangcheng Yayuan, a farmhouse restaurant near Yangcheng Lake in Jiangsu Province, was busy packing hairy crabs and sending them to the whole country. Guo Yangkai, the post-90s boss, has his own docking farm. In the past, he sold hairy crabs by regular customers around him. This year, relying on the advantages of the Internet, he brought goods into the live broadcast room. "On the one hand, online channels attract customers from all over the country, and business can increase. On the other hand, we also want to accumulate passenger flow and word of mouth for restaurants." Guo Yangkai said.

Since the beginning of this year, concepts such as "shopping while eating" have caught fire. In this "double festival", it will become a new trend to enjoy food while walking around the streets because of "food".

The data shows that, near the Mid-Autumn National Day holiday, over 70% of the top ten hot search words related to "food" involved shopping malls and business districts, and the search volume of keywords related to "pedestrian street" and "food" increased by nearly 80% year-on-year. Chongqing Guanyin Bridge, Chongqing Jie Fangbei, nanjing xinjiekou, Wuhan Optics Valley/Luxiang, Shanghai Wujiaochang, Chengdu Chunxi Road, Shenzhen Convention and Exhibition Center, Shenzhen Longhua, Chengdu Huayang and Wuhan Jianghan Road all rank among the top ten in the country in terms of search volume and order volume, and are expected to become the hottest top ten business districts in the Mid-Autumn National Day.

Recently, more and more customers are dragging suitcases to punch in at many restaurants on Jianghan Road Pedestrian Street in Wuhan. "This year, people’s willingness to travel is very strong. Jianghan Road is very suitable for young people to play. It is expected that the passenger flow in the business circle will increase greatly during the National Day, and the queuing time of the business circle stores will be about three or four hours." Zhang Yang, the person in charge of Feifei Shrimp Village, said that the store’s business hours will be postponed for two hours, and group purchase packages for 3-4 people and two people will be added to improve the traffic conversion in the business circle and the service efficiency of the store.

It is worth mentioning that since the beginning of this year, all localities have used consumer gathering areas such as characteristic blocks and commercial complexes as the main carriers, and made full use of scientific and technological means to continuously enrich holiday consumption formats. From September 15th to 17th, wanda plaza in Guangzhou, Shenzhen and other places also went into the online live broadcast room to create a special online and offline food consumption promotion session, so as to create momentum in advance for the National Day holiday. During the Mid-Autumn National Day, the "Lohas Block" built by many governments will land in popular business districts such as Dongguan 33 Town, Chengdu Yulin West Road, Wuxi Nanchang Street, Dalian Gaoxinjin Street, Qingdao Taidong Pedestrian Street and Hefei Gui Street, and plan theme activities around the scenes of "eating, living, traveling and buying entertainment", constantly opening up new space for upgrading and expanding consumption.

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.

　 　 　 　Since Huang Renxun, the head of NVIDIA, put forward that "computing power is the new horsepower", computing power will replace mechanized parameters such as horsepower and torque and become an important standard to measure the strength of automobile products. This argument has been gradually accepted by the industry.

　 　 　 　Once upon a time, the Qualcomm 8155 cockpit platform was called the "car-level chip ceiling" as soon as it came out, and it also became a yardstick to measure the technological level of a smart car.

　 　 　 　After entering the node of "the first year of competition in the era of smart cars 3.0" in 2023, the configuration of involution will go to a higher level. On the occasion of the mass production of 8155, the Qualcomm 8295 chip was very popular. It was launched on the automobile robot Extreme Leap 01 and will be delivered within this year. At the same time, other automobile companies such as Zero Run and Zhiji have followed suit.

　 　 　 　How advanced 5nm technology and 8 times of 8155 terrorist computing power will empower smart cars is very likely to subvert our current imagination of smart cars.

　 　 　 　Some people in the industry have speculated that the Extreme Leap 01 equipped with Qualcomm 8295, 35.6-inch large screen, full off-line voice and advanced intelligent driving will be another "dark horse" of 300,000 level. If Extreme Vietnam 01 can reach less than 300,000, it will make the competition in the already involuted automobile market more intense.

　 　 　 　From horsepower to computing power,chipHow to become the core competitiveness of automobile?

　 　 　 　In China’s new energy market, consumers’ preference for intelligence far exceeds expectations. According to the survey data of Jundi J.D.Power, a third-party market research organization, the intelligent ability of automobiles has become the highest-ranked factor in China consumers’ purchase decision.

　 　 　 　This has also profoundly affected the actions of car companies, such as the ideal of being an intelligent follower, and began to increase intelligence in a big way this year after the basic business was stable. In fact, more car companies have shown profound "intelligence anxiety", and upgrading chips quickly is one of them.

　 　 　 　Behind this change is the change of automobile competition logic. In the era of real smart cars, the competition of intelligent ability of cars is no longer just the cool big screen, but also the "computing power" behind the big screen and the functions realized based on super computing power.

　 　 　 　Qualcomm’s performance in the field of smart cockpit is showing its dominance as in the field of smart phone chips. After the exploration of the first-generation Snapdragon 602A platform and the second-generation Xiaolong 820A platform, the performance broke out on the third-generation cockpit platform Snapdragon 8155A, and it firmly occupied the core position of the smart car cockpit chip.

　 　 　 　It is no exaggeration to say that in today’s smart car market, without the support of 8155, the cockpit system will greatly reduce the attraction to potential car owners. And the scene of car companies "saying what they say is 8155" is very similar to the old story of competing for the first launch opportunity of Qualcomm chips in the era of smart phones.

　 　 　 　As mentioned above, the 8295 chip whose computing power has increased nearly 8 times that of 8155 will be delivered on the automobile robot Extreme Leap 01 soon.

　 　 　 　Obviously, if a smart car can be equipped with a new generation of high-end chips for the first time, it means that the smart car itself is technologically advanced. Secondly, for manufacturers, the first launch will "grab" more time advantages, so that competitors can carry out intelligent function research and innovation in advance, leaving more intelligent expansion space for models, so that smart cars can take the lead when they go public.

　 　 　 　So, how will 8295 chips empower smart cars? Can the industry’s advanced super computing power really solve the "smart anxiety" of all car companies?

　 　 　 　The same chip can make a big difference. Why is it so important to adjust the computing power of smart cars?

　 　 　 　In the era of smart cars, computing power, algorithms and data are three key factors that constitute the intelligent ability of cars. If the mechanical structure of the car is the "skeleton" of the car, then the data can be called "blood", the algorithm is "brain" and the computing power is "muscle". Several elements cooperate with each other to form an excellent smart car.

　 　 　 　That is to say, the intelligent ability of a car is closely related to data, algorithms and the quality of the whole vehicle, especially the algorithm ability, in addition to the bigger and stronger "computing power".

　 　 　 　If the core data of the smart car is missing, the algorithm is backward, or other intelligent hardware has shortcomings, even if it has "violent computing power" as high as 1000 TOPS, it can’t be called a real smart car, but only a monster with "muscular and simple mind". (TOPS is the computing unit of the computer, and 1TOPS means that the processor can perform one trillion calculations per second)

　 　 　 　In a word, you can’t build a real smart car just by computing power. In other words, high computing power chip is a good thing, but it is just like reference materials. If you don’t buy more, the better your academic performance will be. If the car companies themselves do not have the corresponding intelligent support such as software capabilities, even if they use the same chip, they can only produce a lot of wasted "invalid computing power."

　 　 　 　In recent years, traditional OEMs have continuously increased their investment in intelligence and paid a lot of "tuition fees" to compete with new forces. However, due to their deep-rooted traditional attributes and weak software capabilities, the effect of intelligent transformation has improved, but it also seems to be "stumbling."

　 　 　 　For example, although the model of an independent manufacturer is equipped with the top-level 8155 chip, there are still some problems, such as stuck operation, lack of application, slow opening time and low resolution. The actual intelligent experience of the cockpit is not satisfactory, let alone leading.

　 　 　 　"Pinjia" even reported that most car companies are actually "wasting" Qualcomm 8155 chips, and even the most basic fluency has not been done, not to mention giving full play to the potential of 8155, and it may be redundant to use the previous generation 820A. In this case, most car company officials are actually playing "billboards" when they announce that they are carrying the 8155.

　 　 　 　Despite this, it does not mean that the viewpoint of excessively pursuing the computing power of on-board chips needs to be criticized. After all, if a smart car has no "muscle" of computing power, it is not intelligent at all.

　 　 　 　So, how to make the developed "muscles" burst into their due strength? Of course, it depends on a clever "brain."

　 　 　 　Take Qualcomm 8295 chip as an example. In fact, the anthropomorphic metaphor of smart cars mentioned above is exactly the same as the concept of developing automobile robots.

　 　 　 　In the product concept of automobile robots, highly intelligent automobile robots are divided into three parts: brain, nerve and trunk. Among them, the ability related to intelligent driving and intelligent cockpit is "brain", and the intelligent architecture JET is its "neural network", and the structure and power of the whole vehicle always become "trunk".

　 　 　 　JET intelligent architecture is the underlying foundation to create the shape and ability of automobile robots. It can achieve "global integration", which is equivalent to opening up the second pulse of Ren Du and making maximum use of the super-high computing power of 8295. In addition, the basis of the algorithm determines the intelligence of the "brain". Extreme Yue 01 Intelligent Cabin and Intelligent Driving have the algorithmic empowerment of Baidu AI and Apollo. Baidu AI has accumulated more than 10 years of research and development, and Apollo itself is also an L4-level autopilot algorithm.

　 　 　 　Then the effects, such as super smooth interactive experience, super delicate and high-definition visual experience, off-line voice as low as 500ms recognition speed, even when the intelligent driving system fails, Qualcomm 8295 can take over, fully ensuring safety.

　 　 　 　Without exception, traditional car companies are striving for intelligent transformation, and new forces are also spending a lot of money on intelligent research and development. In all fairness, almost no car company has accumulated AI technology for 10 years, and the lack of powerful AI algorithm is one of the reasons why many car companies can’t give full play to the chip computing power.

　 　 　 　By comparing the application of 8155 and 8295, we find the underlying logic of the next generation of smart cars using chip computing power. At its root, products should be user-oriented. If you just blindly strengthen the high-computing power chip, but don’t have the AI ability to play the value of computing power, you can only invisibly increase the cost of car purchase for users.

　 　 　 　For car companies that use 8295 chips later, it is necessary to cultivate AI’s "internal strength", make good use of this "compulsory course" and maximize the potential of high-computing chips and standard them, so as to realize the real universal benefits of science and technology.

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.

　　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)
