Invited to attend the 8th China International Cosmetics Technology Forum, Zhanyan’s bio-recombinant functional protein raw materials attracted strong attention.

From January 24th to 25th, 2024, the 8th China International Cosmetics Technology Forum of InnoCosme 2024 was successfully held in Shanghai. Hou Zengmiao, director of R&D of Zhanyan Bio, was invited to attend and gave a sharing titled "Exploration and Breakthrough of Zhanyan Recombinant Functional Protein Raw Materials", introducing the basic situation of Zhanyan Bio in the field of synthetic biology and its innovative progress in basic research.

InnoCosme 2024 The 8th China International Cosmetics Technology Forum was hosted by Shanghai Business Map and Personal Care Frontier. The theme of the forum was "Biotechnology leads product innovation, insight into the market and opens a new consumption era", which brought together the frontier trends of the industry and invited experts and scholars to discuss and share the development progress of new raw materials and technological innovation breakthroughs.

Based on synthetic biology and consolidating the hard power of scientific research

In the fierce industry competition, the position of scientific research strength is increasingly prominent, and it has become an important factor in enterprise competition. Zhanyan Bio is based on synthetic biology, based on consumer insight and new consumption trends, tackling genetic engineering technology, exploring solutions to skin problems and protecting skin health.

Hou Zengmiao, director of research and development of Zhanyan biological raw materials, introduced at the forum that Zhanyan biological has rich experience in gene design, strain construction, fermentation and purification in the application of recombinant protein expression system of Pichia pastoris and Escherichia coli, and has established a production platform for recombinant functional protein strain construction (Pichia pastoris and Escherichia coli), small-scale production research, pilot-scale amplification research and large-scale fermentation and purification.

In addition, relying on two major genetic engineering research and development platforms, Denoheisi and InPuBoJi, Zhanyan Bio has deployed a large number of terminal applications in the fields of bioactive molecular synthesis biology technology, immobilized enzyme catalysis technology, high-density fermentation purification technology, key technology of recombinant protein anti-inflammatory and healing-promoting, biomedical material construction technology and patented raw material formulation technology, covering the whole industrial chain of bioactive raw materials, biomedical materials, medical terminal products and dermatological grade skin care products.

At present, Zhanyan Bio owns 113 patents, including 43 invention patents, 52 new utility patents and 18 appearance patents. Thanks to the related genetic engineering technology, Zhanyan Bio has realized the research, development and mass production of bioactive materials such as recombinant mussel mucin, recombinant humanized collagen, recombinant fibronectin, recombinant elastin and recombinant superoxide dismutase, and has been applied to many series of products.

Patented preparation technology adds recombinant mussel mucin to realize mass production

Mytilus mucin is very rare. Mytilus mucin acts on the damaged epidermis through film formation, thus playing the role of isolation and protection and achieving good repair effect. However, the traditional natural mussel mucin has low efficiency and the source of raw materials is at risk of being polluted. Easy to use but scarce, its name of "Ocean Gold" was born.

Hou Zengmiao, director of research and development of Zhanyan biological raw materials, said that Zhanyan biological research and development team used synthetic biology technology to break away from convention, established a controllable modification process of mussel mucin dopa in vitro with self-developed and self-produced high-activity tyrosinase, broke through the bottleneck of large-scale mass production of mussel mucin, and innovated endotoxin removal methods to control endotoxin in mass production process with minimum loss. Through various innovative technologies, the recombinant mussel mucin was successfully prepared, in which the purity was more than 95%, the dopa content was as high as 5.81%, far exceeding the requirements of the industry standard of 0.3%, and the endotoxin content was less than <0.5 EU/mg.

Based on its own biotechnological advantages and the functional application of recombinant mussel mucin, Zhanyan Bio has continuously studied recombinant mussel mucin and promoted its clinical application. Up to now, more than 20 papers have been published. The "recombinant mussel mucin for dressing" drafted by Denoheis, the research and development platform of Zhanyan Bio-genetic engineering, was officially implemented in 2023, and five patents related to recombinant mussel mucin have been authorized. Zhanyan Bio has become a pioneer in the research and development and production of recombinant mussel mucin.

A breakthrough was made in hydroxylation-recombinant humanized collagen III and recombinant elastin.

Compared with collagen extracted from animal sources, humanized collagen is derived from human collagen gene, which has better affinity and biocompatibility, higher purity and stability, and at the same time, it puts an end to virus pollution and allergic risk that may accompany animal source extraction. Zhanyan recombinant humanized collagen was prepared by advanced synthetic biology technology, and its core sequence peptide was 100% homologous to human collagen sequence, and it was rich in integrin binding sites such as KGD and RGD. After fermentation by Pichia pastoris, the purity of the final product was ≥95%, and the endotoxin content was < <0.05 EU/mg, which could meet the quality requirements of implantable medical raw materials. Up to now, Zhanyan Bio has achieved the mass production of recombinant humanized collagen III, I and IV, and the research and development of recombinant humanized collagen XVII has been completed, and the patents related to the preparation of recombinant humanized collagen have been granted.

Hydroxyproline is the basic feature of natural collagen, but there is no recombinant collagen containing hydroxyproline in the domestic market at present. After two years of technical research, Zhanyan Bio has broken the technical barrier that non-mammalian expression systems (e.coli and yeast) cannot be hydroxylated without P4H. Through the transformation of Pichia pastoris chassis cells and fermentation technology, the proline hydroxylation of recombinant humanized collagen is realized. At present, the hydroxyproline content in laboratory level can reach 12.279%, which is close to the level of natural human collagen hydroxyproline of 13%. The breakthrough of this technology has promoted the research level of domestic recombinant collagen to achieve a qualitative improvement, and also injected more powerful impetus into the development of domestic skin care products.

At the same time, Zhanyan Bio has also made a breakthrough in the research of recombinant elastin. The R&D team selected the functional core peptide of natural human elastin, took Pichia pastoris as the host bacteria, and obtained the mass-produced recombinant elastin through ultrafiltration, chromatography, endotoxin removal and other processes. The purity of recombinant elastin produced by this technology was ≥95%, endotoxin was < 0.05EU/mg, and HCP and HCD all met the requirements of medical materials standards. Recombinant elastin has remarkable activity of promoting cell proliferation and migration, especially in the anti-photoaging cell model, showing excellent anti-photoaging activity. Recombinant elastin can significantly reduce the activity of metalloproteinase MMP-1 and increase the expression of type I collagen and type III collagen, among which the expression of physiological elastin can be increased by 300%.

Based on biotechnology, Zhanyan Bio has continuously increased its investment in research and development, and made major breakthroughs in many fields such as functional protein raw materials. In the future, Zhanyan Bio will continue to give full play to its scientific research advantages, empower product development and protect the skin health of Chinese people.

The overall leadership of the Party is the "root" and "foundation" of strengthening organizational construction.

Party building forum (plus 100logo)

  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.

The power of ESP is not so simple, it also derives these functions.

[Pacific Auto Network Technology Channel] Automobile safety systems are mainly divided into active safety systems and passive safety systems. When it comes to the former, I believe that most consumers will think of ESP body electronic stability system for the first time, because it is one of the most important safety functions, which can effectively prevent vehicles from losing control and greatly reduce the accident rate. Nowadays, the popularity of ESP body electronic stability system in domestic private cars has reached a high level, and even many models within 80,000 yuan are equipped.
The principle and importance of ESP body electronic stability system has long been a commonplace topic, but its practical application scope has been underestimated by many ordinary consumers. In fact, the power of ESP body electronic stability system is not so simple, because many functions, such as HAC uphill auxiliary control, HDC steep slope descent control, AUTOHOLD automatic parking, AEB active braking system, RSC anti-rolling stability system, etc., are derived from it, and without it, these functions cannot be realized.
HAC uphill auxiliary control
As we all know, it is a technical test for a vehicle to start on a steep slope or a gentle slope with smooth road surface (especially manual gear). The driver’s right foot needs to be switched from the brake pedal to the accelerator pedal. If the action is not fast and accurate enough, the vehicle may slide down the slope. The birth of Hill-start Assist ControL (HAC) is to solve this problem.
In fact, uphill auxiliary control can be called an extended function of ESP, because it is controlled by ESP system. When the vehicle starts on the ramp, even if the driver does not step on the brake or pull the hand brake, EPS will apply braking force to the four wheels at the same time and keep it for 2-3 seconds. This time is enough for the driver to step on the accelerator calmly and improve the driving force without worrying about slipping back. With the increase of accelerator pedal stroke, the braking force of uphill auxiliary will gradually fade, so the vehicle can easily start on the ramp.
The auxiliary control of uphill does not need high cost, but its function is not small, so the popularization rate is already very high. Nowadays, most models equipped with ESP have uphill auxiliary control, and it does not need the driver to set it manually, and it will work by itself when necessary.
HDC steep slope descent control
The Hill Descent Control (HDC) is opposite to the uphill auxiliary purpose. In the steep downhill section, it can automatically control the vehicle at a lower speed to ensure a safe downhill. In the process, the driver only needs to focus on observing the road conditions and controlling the direction, without pedal operation.
In principle, steep slope descent is more complicated than uphill assist, because it is the joint action of engine braking and ESP. This function generally needs to be turned on manually before entering the steep slope. When the vehicle enters the steep slope, the gearbox will remain in the first gear, and the speed will be reduced by engine braking. If the ramp is too steep and the engine braking is not enough to control the vehicle speed, then ESP will intervene and reduce the vehicle speed to a safe range through high-frequency automatic "point brake", which is more delicate than the manual foot brake, so it has higher reliability. It is particularly important to note that if you step on the clutch, brake or accelerator pedal in the process of using steep slope descent, it will immediately fail.
Compared with uphill auxiliary control, the average cost of steep slope descent control is higher, because it is often used in off-road conditions, and the specifications will be different for different off-road vehicles. Steep slope descent control is basically used in SUV models, and now even many domestic SUVs below 80 thousand yuan are equipped.
AUTOHOLD automatic parking
In the city’s congested roads, vehicles often stop and go, and drivers often need to step on the brakes or use the handbrake frequently. After a long time, they will feel very tired, and sometimes carelessness will cause unnecessary accidents. So, is there any way to simplify this process of frequent starting and braking?
Based on the above requirements, automotive engineers have developed AUTOHOLD automatic parking. When the driver steps on the brake, this function will automatically maintain the appropriate braking state, without the driver continuing to step on the brake or pull the hand brake; When the vehicle needs to continue driving, it will automatically sense the throttle action, thus releasing the brake.
The premise of automatic parking is also ESP, because automatic parking is also controlled by ESP components. Its basic principle is to measure the levelness of the car body and the torque of the wheels through a series of sensors, and then the ECU makes a judgment on the slipping trend of the vehicle and issues an execution command. Finally, ESP performs the automatic braking operation, which is similar to the electronic slip-limiting function between wheels of some timely four-wheel drive systems.
It should be noted that the operation methods of different brands of vehicles to perform this function are not uniform. Some of them are automatically performed after stopping completely for about 1 second, while others have to step on the brakes again after stopping.
AEB active braking system
Automatic emergency braking (AEB) is one of the most popular driving assistance functions at present. It can automatically brake the vehicle in an emergency, avoid some collision accidents, and make driving safety more secure.
Compared with the previous functions, the principle of active braking is more complicated and the technology content is much higher. After all, it is a safety function triggered in an emergency. Active braking consists of three parts: perception, decision-making and execution. As the sensing parts, radar and camera are responsible for detecting whether there is a risk of collision with cars or pedestrians in front. ECU electronic control unit analyzes whether it is necessary to send a reminder or take braking measures; Finally, if emergency braking is needed, the actuator will take the initiative to operate. At present, the actuator of active braking is usually ESP, and a few of them are brake-by-wire systems or independent high-voltage accumulator controllers.
In recent years, the active braking function is accelerating its popularization, and many brands have equipped it to models of about 100,000 yuan, taking it as a publicity point. However, it is particularly important to emphasize that with the current technical conditions, active braking can’t guarantee that drivers won’t rear-end vehicles or hit pedestrians in front, so even with it, they can’t relax their attention when driving.
RSC anti-roll stability control
Rollover RollStabilityControl (RSC) is an active safety function for many people, because it is basically applied to off-road SUVs to prevent vehicles from rolling over.
Anti-roll stability control can calculate the roll degree of the vehicle by the signal sent by the wheel sensor when the vehicle is turning on the off-road road surface, and carry out additional control on the middle and outer wheels in the curve. When the vehicle has a serious roll at any time, the anti-roll stability system will quickly adjust the braking force distribution of the wheels on both sides through ESP, and at the same time reduce the torque output of the engine, so as to restore the balance of the vehicle in the shortest time, reduce the risk of body shaking and rolling, and ensure the safety of the vehicle occupants.
summary
After the above analysis, I believe everyone has a deeper understanding of ESP body electronic stability system, which can not only prevent out of control, but also play an auxiliary role in many daily car scenes. In addition to the five functions introduced in this article, it has other functions, and even more and more in the future. You can wait and see. (Photo/Text/Photo: Pacific Auto Network Zhu Shiyong)

Frequent incidents of dog abuse experts and netizens call for speeding up animal protection legislation.

  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."

"Dangerous City" Hung Jinbao guides Liu Qingyun to play the long whip, and he has a lot to do with Gu Tianle

"Dangerous City" Hung Jinbao guides Liu Qingyun to play the long whip, and he has a lot to do with Gu Tianle

  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.

They all say that China’s automobile exports rank first in the world. Don’t ignore this key change.

  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 &mdash; &mdash;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 &mdash; &mdash; 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 &mdash; &mdash; 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&mdash; &mdash; 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.

This golden week has sparked a "taste bud tour" and it has become a new trend to eat while shopping. More than 70% of the hot search words involve shopping malls.

Text/Yangcheng Evening News All-Media Reporter Shen Wei 

Figure/provided by respondents

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.

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.
