International mucopolysaccharide storage care day: love, let’s "stick" together

  When Xiao Hao was three years old, his mother found that his bones became more and more "hard": he couldn’t squat, his arms were difficult to bend, and he was accompanied by hepatosplenomegaly and heart reflux. Sadly, he was never diagnosed … …

  After six years, Xiao Hao was finally diagnosed — — Suffering from mucopolysaccharide storage type ⅱ, thus, a family knows that there is such a rare disease in the world.

  May 15th every year is the International Care Day for Mucopolysaccharide Storage. When children have symptoms such as rough face, stunted growth, thick joints, big head, "chicken breast", hepatosplenomegaly, abnormal heart and even mental retardation, they must be careful of Mucopolysaccharide Storage. Mucopolysaccharide, also known as glycosaminoglycan, is a macromolecular substance widely existing in human cells. Mucopolysaccharide is a big family. Your skin is white and tender, your joints are flexible, and your eyes are bright, which is closely related to the members of the "Mucopolysaccharide" family.

  Although the mucopolysaccharide family is miraculous, there must be a premise that our cells can digest them normally, and the cells have specially prepared a "digestion workshop" — — Lysosome.

  Lysosomes specialize in degrading foreign or endogenous biological macromolecules, such as lipids, glycogen and mucopolysaccharides, etc., and they can take this big job because of more than 60 enzymes contained in them.

  More than 60 kinds of enzymes have their own functions, without any one of them, a specific biological macromolecule may not be degraded normally, thus being stored in lysosomes.

  Lysosomes began to swell, eventually making cells bloated and abnormal, and indigestible macromolecules deposited in various organs of the body, and people’s symptoms became more and more obvious.

  The reason of enzyme deficiency is often gene mutation. Mucopolysaccharide storage disease (MPS) is a congenital genetic and metabolic disease, which leads to the deposition of this kind of mucopolysaccharides because of the lack of enzymes that decompose the corresponding mucopolysaccharides.

  According to the different enzymes, mucopolysaccharide storage disease can be divided into seven types and multiple subtypes.

  Although there are many types, MPS patients have some basic characteristics: multiple organs in the whole body are affected, the development is delayed, and the condition is gradually aggravated; Short stature, rough face, big forehead protrusion, skeletal deformity, thick joints, claw-shaped hands, corneal opacity, otitis media, narrow respiratory tract, hepatosplenomegaly, heart disease, and serious cases will affect intellectual development.

  There are differences between different types. For example, the majority of patients with type II are men, patients with type III show obvious mental retrogression, and patients with type IV concentrate on skeletal deformity. Similarly, the disease has brought a heavy burden to every patient’s family.

  Most of the patients with mucopolysaccharide storage disease are children, and they are affectionately called "sticky babies" in China, because the symptoms of MPS are complex and rare, and there may be many undiagnosed MPS patients who are struggling to seek medical treatment in confusion.

  At first, there was no specific treatment for MPS, and only symptomatic treatment could relieve the pain. In recent years, enzyme replacement therapy has become an effective treatment for some MPS. Simply put, it is "what enzyme is lacking".

  In recent years, with the country’s increasing attention to rare disease groups, the research and development or introduction of drugs for rare diseases is accelerating. At present, MPSⅣA has become the first MPS therapeutic drug approved for marketing in China. Type I and type II drugs are also expected to be listed in China soon. Type III drugs are still under development; However, as far as the drugs on the market are concerned, they are expensive. Without medical insurance, ordinary families will face an unbearable situation.

  If we can use specific drugs from an early age, Sticky Baby can enjoy a high-quality life like us. Even if they can’t take medicine, there are still many MPS patients who insist on going to school or work actively, playing their own part.

  May 15th every year is the International Care Day for Mucopolysaccharidosis. The MPS family in trouble needs everyone’s attention and support. Let’s join these lovely "sticky babies" and hope that the day when medicine can be used will come soon!

Don’t talk about heroes by seniority! The way of talent evaluation "measuring to the end with a ruler" has become history.

  CCTV News:On the 26th, the Guiding Opinions on Promoting the Reform of Talent Evaluation Mechanism by Classification issued by the General Offices of the General Office of the Central Committee of the CPC and the State Council was published. With "classification" as the key word, the Opinions subdivide the evaluation criteria for talents in different industries, different fields and different job natures, and the evaluation methods of talents such as focusing on papers, emphasizing qualifications and "measuring to the end with a ruler" will change.

  "Opinions" implements classified evaluation, based on professional attributes and job requirements, and establishes and improves scientific and reasonable talent evaluation standards covering moral character, knowledge, ability, performance and contribution.

  Yu Jiadong, Director of Ministry of Human Resources and Social Security Professional and Technical Personnel Management Department: "In the past, there was a one-size-fits-all phenomenon in talent evaluation. For example, as we always said, we emphasized education, ability, seniority, performance, thesis, contribution, quantity and quality. There are still some problems in the way of evaluation. For the first-line talents at the grassroots level, the positive incentives are not enough and the inclination is not enough. "

  Yu Xing ‘an, Dean of China Institute of Personnel Science: "For example, in the field of scientific research, if one is engaged in basic scientific research and the other is engaged in technology development, then his evaluation criteria, evaluation methods and measurement indicators should not be the same."

  At the same time, the "Opinions" put forward to pay attention to evaluating talents by ability, performance and contribution. Overcome the tendency of focusing only on academic qualifications, qualifications and papers, rationally set and use evaluation indicators such as papers, solve the problem of "one size fits all" evaluation criteria, and carry out differentiated evaluation of different talents. In addition, the evaluation of scientific spirit, professional ethics and professional ethics will also become an important standard for talent evaluation.

  Who will judge? Peer review and social review

  In view of the problems existing in the current talent evaluation, such as single subject, weak evaluation professionalism and convergence of evaluation methods, who will evaluate talents after the reform? What is the evaluation cycle?

  The "Opinions" first clarified the industry evaluation mechanism based on peer evaluation, and at the same time played the role of multiple subjects such as market and society. According to the characteristics of different talents, different evaluation methods are adopted. Break the restrictions on household registration, region, ownership, identity and personnel relations, and smooth the channels for talent declaration and evaluation in non-public economic organizations, social organizations and emerging occupations. We will improve the methods for reporting and participating in the evaluation of the introduction of overseas high-level talents and foreign talents.

  Yu Jiadong, Director of Ministry of Human Resources and Social Security Professional and Technical Personnel Management Department: "Peer-to-peer evaluation, expert evaluation, can integrate social and market-oriented means, rather than a single administrative means."

  At the same time, the "Opinions" also clearly set the evaluation and assessment cycle scientifically, explore the implementation of the employment evaluation system, and appropriately extend the evaluation and assessment cycle for basic research talents and young talents.

  How to comment? What are you doing? What are you judging?

  Science, teaching, literature and health, everyone works in different fields of economic development. The Opinions issued this time are relevant to everyone and realize "what to do and what to evaluate".

  Yu Jiadong, Director of Ministry of Human Resources and Social Security Professional and Technical Personnel Management Department: "It mainly mentions six major fields, namely, scientific and technological talents, philosophy and social sciences, cultural and artistic talents, educational talents, medical and health talents, and technical and technical talents. The sixth one is enterprise talents, young talents and grassroots front-line talents."

  For scientific and technological talents, the Opinions emphasize the implementation of representative achievement evaluation and pay attention to the combination of individual evaluation and team evaluation. For talents in philosophy, social sciences and culture and art, Opinions are classified and evaluated according to different disciplines and types such as humanities, social sciences, culture and art..

  For educational talents, the Opinions regards teaching and educating people as the core content of evaluation, and scientifically sets the evaluation content according to the characteristics of teachers’ responsibilities in different types of universities and different positions. Highlight the evaluation of education and teaching performance, and strengthen the assessment of teaching quality and classroom teaching discipline.

  For medical and health personnel, the Opinions strengthen the evaluation of clinical practice ability of medical and health personnel, improve the evaluation index system covering medical ethics, clinical practice, scientific research and teaching, public health services and other factors, and reasonably determine the evaluation focus of talents in different medical and health institutions and different professional positions.

  For technical and skilled talents, the Opinions establish and improve the evaluation criteria for engineering and technical talents in different professional fields, and strive to solve the problem that the evaluation criteria are too academic. For skilled talents, we will speed up the construction of multi-level professional standards and improve the multi-evaluation methods such as vocational qualification evaluation, vocational skill level determination and special vocational ability assessment.

  In view of enterprises, grassroots frontline and young talents, the Opinions increase incentives and expand career development space.

  Yu Xing ‘an, Dean of China Institute of Personnel Science: "For a comrade who works at the grassroots level, how can you ask him to have so many papers, and he has such a high degree and such a deep qualification? Therefore, I am afraid that we should relax some standards in the evaluation of comrades working at the grassroots level, so as to really attract our vast number of talents, the vast number of science, education, culture and health workers, and go to the front line to do services and make contributions. "

  How to manage? Unit leadership will have supporting policies.

  How to implement the reform? The Opinions clearly respect the leading role of employers, and a number of reform supporting programs will be launched in the future. The Opinions clarify that the leading role of employers will be respected in talent evaluation, the talent evaluation authority will be reasonably defined and decentralized, and qualified universities, research institutes and other enterprises and institutions will be promoted to independently carry out evaluation work, promote the organic connection between talent evaluation and training, use and motivation, and maximize the evaluation efficiency. In addition, the "Opinions" clearly need to improve the market-oriented socialized management service system, actively cultivate and develop social organizations and professional institutions for talent evaluation, and undertake the government’s talent evaluation functions in an orderly manner.

  Yu Xing ‘an, Dean of China Institute of Personnel Science: "To untie talents, we should delegate power to the employer, so that the employer can truly have the autonomy of employing people, and can make independent arrangements in terms of post setting, recruitment of personnel, and salary distribution, including performance evaluation."

  In the next step, the Ministry of Human Resources and Social Security will work with relevant parties to study and formulate the division of tasks in the Opinions, and formulate supporting policies for the reform of talent evaluation mechanisms in the fields of science and technology, philosophy and social sciences, culture and art, education, medical care and technical skills.

  Yu Jiadong, Director of Ministry of Human Resources and Social Security Professional and Technical Personnel Management Department: "It should be combined with the implementation of the reform opinions of the professional title system and the reform opinions of the vocational qualification system. The evaluation should be unified with the training and development of talents in front and the use of incentives for talents in the back. "

Beijing Film Festival opens, the top three directors in the domestic box office list are on the same stage for the first time.

For the first time, the top three directors in the domestic box office list are on the same stage.

  BEIJING, Beijing, April 15 (Reporter Zhang Xi) On the evening of the 15th, the opening ceremony of the 8th Beijing International Film Festival was held in Beijing. For the first time, the top three directors in the box office list of domestic films were on the same stage. Among them, Jason Wu, director of Wolf Warriors 2, said that China filmmakers are working hard to be craftsmen, and China audiences are increasingly supporting domestic films. He said frankly, "As long as the audience likes it, it is worthwhile to suffer again."

  This year, the Beijing International Film Festival continues the seven main activities of the Tiantan Award, the opening ceremony, Beijing screening, Beijing planning theme forum, film market, film carnival, closing ceremony and award ceremony.

Wong Kar-wai speaks. Image source: Video screenshot

  As the chairman of the International Jury of the Tiantan Award, Wong Kar-wai, a well-known director, said that although judging a movie can be very subjective, different people have their own tastes, but good movies must have one thing in common regardless of the theme and length, that is, the concentration and persistence of the creators.

  Wong Kar-wai mentioned on the stage that when he was drinking soybean milk in a shop recently, he saw the words "I am willing to grind for you all my life" written at the bottom of the bowl, and he was deeply touched. In his view, although grinding beans and making movies are two different things, spirit and temperament are closely related. "I remember the famous director Mr. Yasujirō Ozu once commented on his creative process. He said that he just opened a tofu shop and only sold tofu. So I believe that only through this purity can an excellent work be achieved, so I value this purity. "

  At the opening ceremony, for the first time, the three directors who won the first place and the third place in China box office were on the same stage. As the third-place director of Detective Chinatown 2, Chen Sicheng said with emotion that at first, a cinema manager pointed out that the film’s 123-minute length was too long, and suggested that it would be more beneficial to arrange the film if it was cut to 90 minutes. "But I hope to put ‘ Tang Tan ’ As a brand, the audience’s word of mouth is far more important than the box office, so I persisted. "

  Lin Chaoxian, the director, said that no matter whether it’s "operation mekong" or the box office hit Operation Red Sea, such war movies are very tiring to shoot, but he likes them very much. "I like this kind of movies that make people excited and have positive energy.".

  Jason Wu, the director who won the box office title with the film Wolf Warriors 2 last year, is also impressed on the stage today. "I was still very uneasy when I recommended Wolf Warriors 2 at the Beijing Film Festival last year. The film took three years from preparation to shooting, and finally presented 4,077 shots, which won 159 million people’s views. This shows that China filmmakers are trying to be craftsmen, while China audiences are increasingly supporting domestic films. As long as the audience likes it, they will suffer again.

  Later, the three directors also looked forward to China’s films in ten years. Lin Chaoxian thought that there would be more and more realistic films, Chen Sicheng hoped that more foreign audiences would see China’s films, and Wu Jing bluntly said, "We need to study hard and exercise hard in this decade, and Do not forget your initiative mind will serve China’s films for another ten years."

  It is worth mentioning that the shortlist of the Tiantan Award of this year’s Beijing International Film Festival was also announced at the opening ceremony. After five rounds of screening, 15 films from 19 countries and regions were shortlisted, including two China films such as Eighteen Cave Village in Operation Red Sea, and 13 overseas films such as Dark Wind, End of Journey in Britain and Scorching Summer in Iran.

Sun Honglei interprets the mix and match style "green trousers" and Bao Beier distorts fashion.


creator in chief


"Green Pants" Bao Beier


Bao Beier and the "green pants shape" on the poster at the back set each other off.

   The Chinese comedy movie "The Battle of Shama Town" finally broke through the fog to reveal its deity and made its grand premiere on June 23rd. Director Li Weiran, together with Sun Honglei, Lin Chi-ling, Huang Hai Bo and Bao Beier, made their debut at Sina Entertainment to promote the film release.

  The Battle of Shama Town broke the traditional Chinese comedy style, and the word "original" took the lead. The film’s leading actor is even more subversive, including Sun Honglei and Lin Chi-ling, who have made great breakthroughs in both modeling and deductive techniques. Bao Beier, a young actor who has gradually emerged in the film and television circle, has become the focus of media discussion with his "green trousers" style.

Green Pants Mix and Match Fashion Show Bao Beier Leads Fashion Style

  No matter from which actor, the shape of "Battle of Shama Town" is a major feature of the film. Li Weiran, the director, revealed that these clothes didn’t have much features when they first arrived at the crew, but the popular "mix and match style" of the "Final Battle" crew brought full inspiration to everyone. So under everyone’s careful mix and match, Lin Chi-ling’s "Rose of Chopper", Sun Honglei’s "Sharp Village Head" and Bao Beier’s "Green Pants" were released. In addition, Bao Beier added a lot of originality to his green trousers, such as the "urinal opening" at the back and the "thigh gap" looming, all of which became the highlights of the whole play, which was impressive. So that when Li Liqun first came to the crew, he saw the image of Bao Beier and said, "Xiao Bao, I want to go crazy when I see your green pants." Sun Honglei said with a smile: "Some friends from the French and German fashion circles are very interested in Bao Beier’s green wool pants, saying that it is very promising to lead the fashion trend in the next few years."

For the first time, I joined hands with nervous people in Bao Beier, Sun Honglei.

  Bao Beier, who became popular in the entertainment industry with his superb acting skills, was once praised by many audiences as "Little David". Bao Beier said with a smile: "I wanted to take the idol route, but the food of the crew was too good, which was self-defeating and distorted." Compared with the unkempt image of "touching the dog" on the poster of "Battle of Shama Town", Bao Beier lost a lot of weight. When talking about the reason, Bao Beier laughed. "I was a normal person. For the first time, I cooperated with big names like Brother Hong Lei and Sister Zhiling. I was so nervous that I couldn’t sleep well, so I was swollen." The master revealed that Bao Beier’s "Touching the Dog" was not a fool at first, but under Bao Beier’s repeated experiments, discussions with the director, second creation and "everyone’s help and pressure", what was presented to the audience was "Touching the Dog", which was different from the original script. Although this image was quite distorted, it became a classic of the film and added a lot of color to the film.

  In addition, Bao Beier admitted that the biggest treasure he "dug up" when filming "The Battle of Shama Town" was his cooperation with other actors, and he "benefited a lot from them". Li Weiran, the director, also said that it was like working together to achieve a dream. "The sense of fulfillment is indescribable.".

Movie network point of view: The funny modeling of "Green Pants" Bao Beier will be the highlight of the film, but the stars such as Sun Honglei and Lin Chi-ling are the focus of the film’s box office.

Deng Chenghao: How is the dark blue SL03 made?

The emergence of the Deep Blue SL03 surprised everyone. In early April, the two review editors of the First Electric Editorial Department accidentally found the car on the streets of Chongqing. After taking a look, they took a set of spy photos and sent them out, which triggered a warm response from the whole network. At that time, there was a feeling that after years of silence, Changan New Energy finally made a big move.

From July 10th to 11th, we test-drove the pure electric version and the extended-range version of the Deep Blue SL03 in Chongqing. We were deeply impressed by the excellent handling, solid chassis, precise steering, quite mature exterior interior, and balanced smart cabin smart driving configuration. What was especially amazing was that during the test drive of the extended-range version, the two people switched on, just to hear when the range extender would start, and both failed – not only did they not hear the sound at all, but they did not feel the vibration at all – so much so that we ended up wondering if the range extender was installed and went to check the exhaust pipe for heat waves.

This is definitely one of the most surprising and explosive products so far in 2022, and it is no less exciting than the Wuling Hongguang MINI EV and Ideal ONE in 2020.

Unbelievable. How did the group of people in this mountain city who have been taciturn for a long time create such a car? Was it luck by mistake, or did you think it through and make it from the beginning?

The conversation at noon on July 11 began in such a state of mind. In the time of a meal, the answer is self-evident. At that time, the specific time for listing and releasing the configuration and price has not yet been determined, only until the end of the month. In order to live up to the trust of Deng Chenghao and his team, we waited patiently, waiting for a suitable time to tell readers the stories that happened behind Deep Blue SL03.

In fact, we want to tell the reader is: Changan out of a good product manager. And this should be considered lucky Chongqing.

Deng Chenghao:In 17 years, Changan Automobile talked about a "Shangri-La Plan". Many people in the industry felt that Changan was painting big cakes and did not really do it. In 17 to 20 years, we sold very few electric vehicles. In 2021, we sold 100,000 units. In fact, everyone was very skeptical.

Pang Yicheng:In fact, you are serious about it, but you just didn’t say it?

Deng Chenghao:In fact, before the release of the "Shangri-La Plan", I was working on this platform in May 2017. I was in charge of the planning of the entire technical direction. The first time I planned this platform was called EPA1. In my technical planning, I believed that it was impossible to change the future tram with oil trucks, which was not competitive.

Pang Yicheng:You were the chief engineer at the time, right?

Deng Chenghao:No, I am the technical director and I am responsible for technical planning.

I said that in order to arrange the engine well, the front suspension of the oil car is very long. The front suspension of the oil car you see is very long, in fact, the wheelbase is not that big. But in the era of trams, batteries are the highest cost, accounting for about 50%. It is impossible to not use the most expensive things to make the best layout, and to achieve the best competitiveness in this market.

In 2017, the group agreed to set up a research project, and there were three new platforms in my technical plan, which were the three new pure electric special platforms mentioned in the Shangri-La plan. I worked hard in 17 years, and in 18 years, I really started to invest in this platform. It was estimated that I would have to invest a lot of money, and everyone was still torn.

Pang Yicheng:Torn what?

Deng Chenghao:How much was the investment in torn? At that time, we calculated that the investment in the platform alone must be 2 billion yuan, and the production line is not mentioned, only the R & D investment and the supplier’s investment. Previously, Changan was one platform for one car, but now it needs to build a new platform, and it is still a tram. Can you find some people to do it together instead of doing it yourself? Wait.

Although we have torn the R & D model, the technical route has never been torn.In this process, we did something that is very correct now, and it is also something that affects the product’s genes. This is to determine the platform genes for post-drive. We are very tough on this point.

Pang Yicheng:Tell me about this first, why?

Deng Chenghao:Of course, I do performance, I do technology, and I know what the meaning of rear drive is. I think rear drive in the era of the gasoline car is extremely expensive. You see the BMW 3, for rear drive, rear seat space is sacrificed. Some four-seaters are actually forced to choose four-seaters brought by rear drive.

In the era of the oil car, the engine was too large to be placed in the back. It had to be placed in the front compartment to dissipate heat. To make the rear drive, it must have a transmission system that had waste space and waste oil. In the era of the tram, the motor was too small to put anywhere, and it was very easy to put the rear axle. In the era of the oil car, consumers wanted the rear drive, but they couldn’t afford the rear drive. Because of the high cost, its input-output ratio was very uneconomical, so consumers just bought the front drive.

In the tram era, there is basically no increase in investment. The rear drive system of a tram is only 1,000 yuan more expensive than the front drive system of a tram, and the rear drive suspension system is more expensive.Can 1,000 yuan bring a rear drive? Why not do it?

Pang Yicheng:You were determined to be a back driver at that time. In addition to advanced technology, was it particularly attractive to you to control this matter?

Deng Chenghao:Handling, customer experience, and its cost-effectiveness. So we decided on the EPA1 platform at that time. The first drive must be rear drive. You can have four-wheel drive, but there is absolutely no single front drive.

Based on the design of the rear drive, the first power project outside the platform started internally was the development of a new electric drive system on the rear axle. The technical route we prepared was a highly integrated all-in-one electric drive system on the rear axle, which was debated many times within the company.

Pang Yicheng:I’m afraid you can’t figure it out, right?

Deng Chenghao:I firmly made it. Technically, we have repeated PK within the electric drive team. If the electric drive needs to be put behind the drive, it means that the external space is very small, but if it needs to be integrated, it means that the volume needs to be increased. This is a dilemma. I mentioned the extreme boundary requirements to the team. I said that if we want to make 6 seats in the future, the last row should not be as uncomfortable as sitting in a sedan chair, and the trunk space should not be affected.

Pang Yicheng:You’re just asking them to make this thing smaller and shorter?

Deng Chenghao:The most difficult indicator is to be short and flatten the all-in-one. To this end, in 2017 we launched the all-in-one electric drive project, which is very successful today, unprecedented, and the team is very, very awesome.

Pang Yicheng:Who is the technical leader of this project?

Deng Chenghao:One of the deputy general managers of power development, surnamed Du, used to be a hybrid with me. At that time, we set (target power) at 160 kilowatts, and finally made 194 kilowatts.

Pang Yicheng:Amazing.

Deng Chenghao: The first one on the platform is set to the rear drive, the second one is set to multi-in-one, and the third is the chassis, which is the foundation.I said that the rear drive was done, and the adjustment of the chassis was still in the traditional adjustment method, but that didn’t work. I was choosing what direction at that time.

The first gene: sports, otherwise the rear drive is meaningless, so the genes of the chassis must be the genes of sports.

The second gene: the Changan brand is determined, and we are targeting family cars. Comfort is very important. What we want is that I feel comfortable when I go out alone, but my parents, wife and children are still very comfortable, taking into account sports and comfort.

After about 19 years, the Model 3 had already begun to rise and was set as the benchmark.

Pang Yicheng:No wonder, it does look like it, and the size is similar.

Deng Chenghao:The choice of genes is clear to balance sportiness and comfort. The car you drive today is very good in the balance of sportiness and comfort. The sportiness is on par with the Model 3 as a whole, but the overall adjustment of the Model 3 is hard, and the comfort of the Dark Blue 03 is also very good. This car emphasizes comfort. It filters shock absorption throughout the adjustment, and the softness of the chassis is done well, including the seats. In fact, comfort is composed of the combined effect of the chassis and seats.

Deep Blue 03 has been in development for three years now, and the platform has been in development for five years. When Deep Blue 03 reached the second half of 1919, we were analyzing the market. At that time, the market was a dumbbell structure with two large ends and a small middle. And our Deep Blue is targeting the medium-sized car and compact + market. If it is just a pure electric vehicle, I feel that it is difficult to create a hit, so I made a suggestion to the company.

Pang Yicheng:Add a range extender?

Deng Chenghao:We now have the rear drive gene, all-round rear drive, the front cabin is empty, you can use it to put a suitcase, and it can be expanded to four-wheel drive. I said is it possible to put a range extender in to extend the mileage? At that time, our research found that electric vehicles have 6 major pain points, short range, slow charging, battery safety, low value retention and a series of problems. The pain point is all the battery, and the cool point is all the electric drive. Just like a football game, the battery and electric drive play at the same time. The electric drive plays well, but the battery plays badly, and it always holds back. To make up for the shortcomings of the battery, you can use the range extender to make up for it. But this technology has a lot of concerns.

Pang Yicheng:Do you think this is a backward technology?

Deng Chenghao:In August 19, Yang Dayong came to work as a new energy supervisor, and Mr. Yang was very supportive of doing this (upper range extension). Deep Blue 03 established two versions of pure electricity and range extension, and hydrogen fuel was only available at the end of 19 years.

Many people say that range extension is a backward technology. In fact, consumers now have a deep understanding of range extension. In 19 years, it was not ideal, and we were just crabs. I said that if you are worried about being backward, I will replace the fuel tank with a hydrogen cylinder, I will replace the engine with a stack, and I will get a hydrogen fuel, okay? The last three power sources are doing very well, so this is where pure electric, range extension and hydrogen fuel come from (laughs).

Pang Yicheng:Was there any cost consideration at that time?

Deng Chenghao:In the early days, the cost difference between pure electricity and range extension was not significant.When we calculated in 19 or 20 years, the difference between 500 kilometers of pure electricity and range extension was only 3,000 yuan, but there was an extra tax on the end of the range extension enterprise, which was about 1.5-3%, basically two or three thousand yuan. So the cost difference is not big.

Later, the cost difference between pure electricity and range extension was widened due to the increase in battery costs. Now the difference is about 8,000 or 9,000 yuan, and there will be a slight gap.

For example, the power performance of the extended range was a little weaker than that of pure electricity. Zero hundred acceleration could not reach 5.9 seconds of the current pure electric version, but it could also reach more than seven seconds.

Pang Yicheng:That’s better than a gas car.

Deng Chenghao:Yes, compared to the oil truck, it is still a seckill.In fact, our early PK targets were Accord and Civic.We also studied a few other products at that time.

Electrification in China has actually pulled the brand up, or consumers’ recognition of domestic products is also getting higher and higher. The electrification wave is the most suitable for brand growth, so now a number of independent brands have launched new brands based on electrification, which are much higher than the original.

In the era of gasoline trucks, you can’t get a joint venture brand with your own brand. But in the era of trams, we went earlier than foreigners, with better technology, and we have a leading opportunity. Deep Blue 03 aims at the joint venture market, to hit your price, and it is deeply intertwined with it. What are your advantages over it?

The first major advantage is the impact of electrification. Most of the joint ventures are still selling oil trucks, which is not in line with the historical trend.

Second, the digital experience is completely spike, leapfrog. You go to drive a Japanese car, you look at its intelligent properties.

Third, the decision-making efficiency is higher. Our grasp of technology and the efficiency of enterprise decision-making are unparalleled by joint venture brands.

At that time, I and the team agreed on three words.The first word is called accounting, and hydrogen fuel is called forward-looking occupation in the technology circle,We want to demonstrate that we are the best at home.

The second is to grab, and it will definitely grab the market of more than 200,000 digital electric vehicles. To put it bluntly, it is the market for products like Model 3 and Seal. I have the same experience as you, but I am more price competitive than you.

The third is to transfer to a joint venture fuel vehicle. To increase the range is to harvest the first-line joint venture market. The first-line joint venture is now selling for 145,000 yuan, plus a purchase tax of 167,000 yuan. I say we have a great opportunity to reduce the dimension.

Pang Yicheng:And if you go by the smallest particle, it’s a Civic, right?

Deng Chenghao:Yes, the bullseye we were aiming for was the Civic.

Pang Yicheng:It seems that this is not accidental. During the test drive yesterday, I felt that this car was designed for Model 3 and Civic, and there was a big question mark at that time: Did the author think so?

Deng Chenghao:Haha, that’s exactly what I think. This product is still very troublesome to this day. There are more than 2,000 of us here, and we have been working on dark blue series products for the past three years. I often drive to the mountains at 11 or 12 o’clock in the evening. Because I do technology, I like to be quiet and go around the mountain in the middle of the night. At this time, I can calm down and feel the state of the car best.

Pang Yicheng:I have two small questions. First, why is your range extender naturally aspirated and not turbocharged?

Deng Chenghao:Japan does hybrid power, why choose natural suction? My point of view, single-motor hybrid power, Germany likes to use T to match, for example, Volkswagen, add a large motor to every 1.5T engine.

No matter whether it is Honda series-parallel or Toyota power shunt, these technical routes tend to use hybrid dedicated cycle engines, such as Atkinson, rather than turbocharging, because the combination of two motors + one engine and three powers, the instantaneous power mainly depends on the motor and battery, and does not require the blessing of turbocharging. It is best to use natural suction, which is smooth and can improve the overall efficiency.

Pang Yicheng:You mean better fuel economy?

Deng Chenghao:This is the first reason why we choose to do 1.5 liters of naturally aspirated, using deep Atkinson cycles and ultra-high compression ratios, that is, the compression rate of deep compression is very high.

The second big reason is that I had a dream when I was doing range extensions, wanting users to drive with only one feeling, and that was pure electric.

Pang Yicheng:Got it, you don’t want users to feel that kind of pause or shock.

Deng Chenghao:Yes, it is pure electric when it is driven, and it looks pure electric. At that time, I asked for the shape of the range extension to be exactly the same as pure electric. The front cabin of the dark blue 03 needs to be equipped with an engine. If you want to do turbocharging, the temperature near the turbine is very high, and its heat dissipation requirements will be very large, so it cannot achieve the shape of pure electric.

Pang Yicheng:Is the air intake grille the same as pure electricity?

Deng Chenghao:The same, the world’s first range extension and pure electric modeling have the same front face shape, no one.I want to make users feel that there are great benefits: I bought an electric car, which is purely electric and feels futuristic, but there is no mileage anxiety, the driving experience is excellent, and I can’t feel the range extender working. The sound is very pure.

Pang Yicheng:Is it not a cost consideration?

Deng Chenghao:No, it’s for experience. Recently, many colleagues have bought a closed test car and are driving it themselves. It feels completely different from a fuel car. Not only is the driving smoothness not like a fuel car, but the sound is not like a fuel car, and the vibration of the vehicle is not like a fuel car.

Pang Yicheng:Your power loss and fuel consumption are also four o’clock?

Deng Chenghao:If it is WLTC, it is 5.0L, and CLTC is about 4.5.

My car is 300 kilograms heavier than Qin. Qin is about 1.5 tons, and I have 1.8 tons. Overall, it is relatively solid, and the fuel consumption is relatively satisfactory.

Pang Yicheng:Second small question, why don’t you use both fork arms for your front overhang?

Deng Chenghao:It’s a bit of a challenge if I use two forks, because I have a very short front overhang.

Pang Yicheng:The two fork arms will take up some internal space, and your range extender may not fit?

Deng Chenghao:Yes, we ended up with the McPherson suspension. The McPherson is also an independent suspension. We did a very careful adjustment and the effect is very good. It took a lot of effort. The driving performance of this car is obvious to all. I am very, very confident that there is no one in the whole market!

Pang Yicheng:Can the pure electric version be used with double fork arms?

Deng Chenghao:It can be used, but it is not good to platform it.

Pang Yicheng:How to set the production and sales target for this product?

Deng Chenghao:For the target of Deep Blue 03, I have prepared 35 ladders, that is, 35 cars an hour, 700 cars in 20 hours a day, and 26 days in a month, 26 × 700, which is the production capacity I have prepared.

Pang Yicheng:That’s 18,000 units per month. Is the capacity ready now?

Deng Chenghao:I’m ready. The supply chain and batteries are fine, and there is a small problem with the chip, but the problem of the chip is mainly affected by the guarantee of the chip industry. I am familiar with the chip. We have been preparing for more than a year for the guarantee of the chip of Deep Blue 03, and the problem should be manageable.

Pang Yicheng:If nothing else, the monthly production capacity will reach 18,000 units by Q4, or has it been reached now?

Deng Chenghao: My goal is to exceed 10,000 units in September, 15,000 units in November, and 178,000 units in December.

Pang Yicheng:That’s pretty much what we anticipated.

Deng Chenghao:My goal is to achieve at least 1781 monthly volumes of this product. There are still two things that consumers have not yet seen through.

The first is configuration. Consumers don’t know what configuration we have.

The second is the price of the configuration. We have released a pre-sale price range, not talking about the configuration, and the pre-sale price is not the listing price. Listing price and listing configuration, this topic is very important.

Pang Yicheng:Listing price, we guess, is it possible to reach more than 160,000 start?

Deng Chenghao:It’s not decided yet.

Pang Yicheng:Channel You are going to be a direct-operated store, right?

Deng Chenghao:Direct sales, using the model of investor investment, mainly borrowing the original dealer resources of our group, opened 100 stores on July 15th.

Pang Yicheng:The storefront is their investment, but they don’t need to eat the inventory?

Deng Chenghao:No, the inventory is in my hands. There are 100 on July 15th and more than 500 across the country on August 15th.

Pang Yicheng:How many cities can be paved?

Deng Chenghao:The key cities of the first, second and third tiers are all covered. The focus is on 95 cities with a high share of new energy. Because we have extended the range, a lot of cities outside 95 cities have also been invested, totaling more than 200 cities.

Pang Yicheng:Are these bosses willing to invest in it?

Deng Chenghao:Very willing to transfer the best position and the best sales ability.

Pang Yicheng:Renovate his original store?

Deng Chenghao:Changed.

Zhang Hao:I have a question, is there some platform reservation for smart driving? We see two places on the fender, which seem to be reserved for the camera?

Deng Chenghao:The first batch is IACC, and we will release more and higher-level intelligent driving services after December 31st. It can be selected when it goes on sale, but it cannot be delivered now because its hardware cannot be pre-embedded. There will be two new functions at that time. On the basis of the current IACC, add intelligent lane change assistance on high-speed roads, road selection and on-ramp assistance.

The first increase is to increase the ability to judge left and right on the basis of only forward and backward judgments.

The second addition is parking, which allows for smart parking across floors.

Pang Yicheng:Parking across floors using Huawei’s system?

Deng Chenghao:It’s our own. Our research found that in fact, consumers really use city-assisted driving scenes less. High-frequency scenes are on highways, and there is parking. Cross-floor memory parking is more practical for consumers. It can remember, just like your own home. If he walks once or twice, he will remember the parking space. This function will not be available until the end of the year.

Zhang Hao:The reserved position on the fender, is there a camera when it is delivered?

Deng Chenghao:No, we will let users choose (optional package) in this listing, but the delivery time is relatively late.

Pang Yicheng:After the configuration and price are officially released, how many orders are you going to accept?

Deng Chenghao: My goal is to receive at least 50,000 units in the first month.

Pang Yicheng:According to your current booking situation, how about the user portrait?

Deng Chenghao:This time, 95% of them were between the ages of 20 and 35, and they were mainly highly educated. But it may be related to our communication, but it has not spread yet. The tens of thousands of users who book now are basically the first and second lines, which means that the circle has not expanded yet, and it will take some time.

Pang Yicheng:So the median age is about 27, 28?

Deng Chenghao:Almost, about 30 years old, 20 to 25 years old, there are still more than ten percent, and now the newly graduated college students have good spending power.

Pang Yicheng:Extended range and pure electric, which version will be more popular?

Deng Chenghao:At first, I wanted to increase the range by 60%, 40% pure electricity,The production capacity prepared now is about half to half.

Pang Yicheng:I don’t think it is possible to match half to half, and the range increase will definitely be more. The first car of a young person must have two characteristics, the first is Sa, and the second is not to have mileage anxiety.We believe it should be 8:2, the absolute advantage of range extension.

Deng Chenghao:China’s past policies have resulted in a lack of supply in the PHEV market, and so far the supply has been completely insufficient.

Now, the largest group of 20 million consumers in the gasoline truck market is coming, and they still have potential range and charging anxiety to this day. As the initial consumer enthusiasm passes, by the time the calm consumer enters the market later, his thinking will change and shift.

Pang Yicheng:In the 15 to 200,000 range, this is the most competitive product we have seen so far. In the past, neither pure electricity nor range extension has been successful in this market. In the past, it was a blank, and major changes may occur this year.

I checked yesterday that the volume of the Civic has dropped. The highest in 2020 was 26,000 a month. The market fluctuates a lot this year, sometimes 8,000 a month, and sometimes more than 10,000 a month. We judge that after your product is released, if there are no mistakes in marketing, the actual volume should have a chance to break 10,000. The Civic market has a good chance of being taken away by you. Maybe you can also get a little from Accord and Camry.

Deng Chenghao:After looking at the competitive relationship data, including Han, P7, and C01, in fact, they all grabbed Accord, then Camry, and CRV.

Pang Yicheng:Among all B-class cars, the current strongest is the Camry, which is very stable. It grew by 26% year-on-year from January to June this year, and the only single product rose. When is your second SUV ready to come out?

Deng Chenghao:First half of next year.

Pang Yicheng:Then the second half of the year is that big car?

Deng Chenghao:The year is 2024.

Pang Yicheng:Is the SUV on the same platform as this one, or is it a dual route?

Deng Chenghao:Right. The dual route is an accurate option, and even the extended range on the track is very cool, which is something that the oil car dare not imagine.

Pang Yicheng:If you put a double fork arm on the electric high-end board, will it make the chassis more resilient?

Deng Chenghao:We are also working on sustaining this platform to try to explore its limits. At the same time, I have always wanted to develop a track mode, where the ESP is turned on, not turned off, and then adjust its limits.

At the end of last year, the track mode was developed in the challenge arrangement, but it was too late in the winter at the end of last year. With the ESP in effect, the vehicle as a whole is relying on safety. Finally, you find that turning off the ESP is purely relying on the chassis. Its attitude control is very good, and it is easy to throw, which means that the hardware safety boundary of this car is very stable.

Because most people are afraid to turn off the ESP, when the ESP is turned on, it is our continued pursuit to let consumers experience the best aspects of driving control.

Zhang Hao:But this point is actually very difficult for ordinary users to get, yesterday we tried the feeling, this car is very similar to the venue modified car, if you drive very intensely, you can feel the ability of the chassis is quite OK.

Deng Chenghao:There is a group of people in the Model 3 consumer crowd who buy and play, and that group of people gives your brand a strong driving force.

Pang Yicheng:We were also talking about this issue yesterday, saying whether it is possible for Changan to keep a fleet. Before this product, Changan did not have such prominent driving control products, right?

Deng Chenghao:Our company leader took this product and opened it, saying that this product is completely different from an oil truck.

Pang Yicheng:Regarding the future of pure electricity and range extension, please ask for your opinion.

Deng Chenghao:Our second rear-drive car is an SUV, which is also a pure electric range extension dual power.

If you want to do it smaller in the future, focus on pure electricity to create a small steel cannon that young people like. If you do it bigger, you will mainly increase the range.My point is that the bigger it is, the more it should be extended.

Nowadays, some people engage in large SUVs of 600 or 700 kilometers that require a 120-degree battery pack. I think there is something wrong with this logic. In the short term, the so-called next-generation technology will not be available until 2030.

Pang Yicheng:Do you think there will be no fundamental change in battery pack density before 2025?

Deng Chenghao:There will be some improvement, but it is difficult to make a fundamental leap. Even before 2030, I don’t think solid-state batteries will be fully commercialized.

In addition, some people feel that the battery would have been at a high level under the current process, and I think the cost will also return to the downward channel.

Because the upstream expansion of production capacity is much faster than we thought, demand is rising, and supply is also rising. It turned out that supply could not keep up with demand, so the upstream raised prices desperately. But when supply catches up with demand, the cost of battery packs will gradually decrease.

When I took over as CEO of Deep Blue last September, the battery was six or seven cents, and now it is one or two. This crazy situation will soon pass.
