How to break the industry difficulties when the signal of centralized collection of Chinese patent medicines comes out?

On August 9, 2021, the National Medical Insurance Bureau issued the Reply of the National Medical Insurance Bureau to Recommendation No.4126 of the Fourth Session of the 13th National People’s Congress, stating that "on the basis of improving the quality evaluation standards of Chinese patent medicines and formula granules, we will adhere to quality priority, take clinical demand as the guide, and start with high-priced and large-quantity varieties to scientifically and steadily promote the centralized procurement reform of Chinese patent medicines and formula granules".

The introduction of this reply means that the procurement of Chinese patent medicines and even granules has been put on the agenda. However, as the first batch of people in China who participated in centralized drug bidding and purchasing and engaged in big data research of traditional Chinese medicine for a long time, the author is not optimistic about the procurement of traditional Chinese medicine in the short term.

Say so, we might as well stroke the train of thought:

01

What is the quantity purchase of traditional Chinese medicine?

"Drug procurement with quantity" refers to defining the procurement quantity when bidding or negotiation is carried out in the process of centralized drug procurement, so that enterprises can quote according to the specific quantity. This procurement method is also the goal that China has been striving to achieve for many years. In fact, this method is also an upgraded version of the centralized bidding and purchasing of drugs in medical institutions nationwide since 2000, which is no stranger to the vast number of pharmaceutical and medical device manufacturers at home and abroad. However, it is really a new thing for domestic Chinese medicine production enterprises, especially Chinese medicine decoction pieces enterprises.

Let’s start with the following basic definitions of popular science:

First, which Chinese medicines can be included in the quantity procurement? The "traditional Chinese medicine" that can be included in the quantity procurement mainly includes Chinese patent medicines and Chinese herbal pieces (including new-type pieces and formula granules) used in clinical practice in medical institutions.

Second, what is quantity procurement? Procurement with quantity is relative to centralized procurement, which can be understood as large-scale "group purchase" or "group purchase", that is, many hospitals form a "procurement consortium" to conduct similar "group purchase". At present, in areas where quantity procurement is implemented, the purchased products need to account for 60%-70% of the total usage, which is equivalent to a big "group purchase". Purchase with quantity, specify the purchase quantity, and the manufacturer will quote and negotiate, and the lowest price will win the bid. Enterprises can reduce the price of purchased drugs and increase the market share of products through market-oriented bidding with quantity, which is beneficial to both supply and demand sides and drug users.

Third, which institutions can carry out centralized procurement and quantity procurement? At present, it is mainly enforced in non-profit medical institutions under the supervision of medical insurance and medical and health authorities (note that it is not non-profit or non-profit). Social organizations such as retail pharmacies can also spontaneously organize "purchasing consortia" to carry out "group buying", which is referred to as "GPO purchasing" for short, but it is often not mandatory by policy.

Fourth, what does "4+7" procurement with quantity mean? It refers to the first batch of 11 pilot cities promoted by the state, including 4 municipalities directly under the central government and 7 provincial capital cities: Beijing, Tianjin, Shanghai, Chongqing, Shenyang, Dalian, Xiamen, Guangzhou, Shenzhen, Chengdu and Xi ‘an, which basically covers half of the domestic clinical drug circulation. These cities will take out more than 50% of the purchasing share every year, which has a great relationship with the market share of production enterprises and is a matter of life and death.

Therefore, once the country promotes the "4+7" or even nationwide procurement of traditional Chinese medicine, it will surely become a key event for Chinese medicine enterprises, which is expected to cause a major reshuffle of the Chinese medicine industry, and the industry must pay attention to it.

02

Why is it difficult to implement the procurement of traditional Chinese medicine for a long time?

Before answering this question, we must clarify two points:First, the centralized bidding and purchasing of proprietary Chinese medicines has been carried out around 2001, and the effect of reducing fees is very obvious, but it has not yet been included in the "4+7" procurement; Second, the centralized bidding and purchasing of Chinese herbal pieces. As early as 2001, the documents No.308 and No.309 jointly issued by five ministries and commissions in the State Council all proposed to "actively explore the centralized bidding and purchasing of Chinese herbal pieces".

However, it was not until 2018 that attempts were made in Shanghai, Gansu and other places, and the effect was not obvious; In July 2020, 12 provinces, including Shandong and Inner Mongolia, directly established a platform for the joint collection and purchase of Chinese herbal medicines, and prepared to carry out large-scale procurement activities of Chinese herbal medicines. However, the thunder and the rain are too small, and there is no more.

Why can’t centralized bidding or quantity procurement of traditional Chinese medicine products be promoted?

The apparent reason is that the overall purchase volume of Chinese medicine products without proprietary Chinese medicines is small, and the overall purchase volume of pieces of Chinese medicine in medical institutions nationwide is less than 56 billion yuan, which is only a fraction of the total purchase volume of chemicals and medical devices, and it lacks attention. But the deep-seated reason is that there are two bottlenecks, and there is no breakthrough for a long time:

The first is the standard issue.

Traditional Chinese medicine (TCM) is a practical weapon of TCM, and its personalized demand is very obvious. A large number of raw medicinal materials and even decoction pieces are agricultural and sideline products, which are non-standard products. You may say that the Pharmacopoeia has the standard of decoction pieces, but that is only the minimum quality threshold, and it can’t cover the complicated and changeable commodity circulation specifications of Chinese herbal medicines at all.

For example, 280 and 380 pieces of Lycium barbarum, Ningxia goods and Qinghai goods, new goods and old goods, although they all meet the pharmacopoeia standards, can they be regarded as the same commodity? Without a unified standard, how to divide the quality levels? If we simply use the Pharmacopoeia standard to evaluate products, it will undoubtedly lower the quality level of Chinese patent medicines and granules as a whole and destroy a large number of well-known brands of Chinese medicine.

Shanghai, Zhejiang and other places are going to separate the products using raw materials from GAP base or traceability base, but everyone in the industry knows that the construction of GAP base in China is difficult to land, and the construction of traceability base is just in its infancy. The concept is bigger than the essence. Can it be used as a criterion at this stage?

At the same time, even if you establish a commodity circulation standard, will this standard be recognized by both the supply and demand sides? How to run through the whole process of Chinese herbal medicine raw materials, Chinese herbal pieces, granules, production enterprises, products and demand side is a very difficult and grand project, which can not be straightened out by a single link.

The second is the price issue.　

The price problem is divided into three levels:

The first is how to define the cost of different quality Chinese herbal medicines. Origin, growth cycle, harvest time, content, appearance and processing technology will all affect its pricing. This problem is actually closely linked to the circulation standard and is an extension of the standard problem.

Secondly, the price fluctuation during the period of centralized mining. The nature of agricultural and sideline products of most Chinese herbal medicines leads to the reality that they still have to "eat by the sky". In the past five years, the price amplitude of Chinese herbal medicines in China has reached more than 18.5%. In August 2020, the same kind of forsythia was 55 yuan (kg price, the same below), and it will rise to 115 yuan in 2021; The raw land has skyrocketed from 11 yuan to 35 yuan. How do you let the successful bidder complete the distribution at the original price?

Allowing the price increase violates the rules of the game of winning the bid at a low price under the same quality, and how to accept the price increase basis? If the price increase is not allowed, the winning bidder will be miserable and it is very likely to lose money to perform the contract; If the roasted seeds and nuts add fuel to the fire and monopolize the raw materials of the winning products to raise the price, the enterprise will even lose the pants, and finally the severe consequences of "winning the bid is death" will not be ruled out.

More crucially, the higher the bid, the higher the price. At present, the principle of "bidding and bidding, the lowest price for supply" is generally adopted in raw material procurement of production enterprises, and all kinds of arrears and deduction of suppliers’ payment for goods have also existed for a long time, so as to minimize the cost of raw materials. If we really realize the so-called "genuine quality and conscientious processing" through centralized purchasing activities, and make the raw material sources and costs of those brand enterprises known to the world, we will inevitably face the embarrassing situation of "more recruitment and higher fees" due to the improvement of quality. Originally, centralized purchasing wanted to reduce prices and control fees, but as a result, the price of centralized purchasing rose sharply. Can the medical insurance department accept it? This is really a paradox.

To sum up, when designing the centralized collection activities of traditional Chinese medicine, the operators often fail to consider the complexity of traditional Chinese medicine products, especially in terms of standards and prices, and lack of fundamental countermeasures and convincing evaluation system, so there are many obstacles in the actual promotion, and most attempts eventually end in vain.

03

How to break the traditional Chinese medicine collection?

It is precisely because of the complexity of the centralized collection of traditional Chinese medicine that the procurement of traditional Chinese medicine in medical institutions has been in a blind spot or even a "gray zone" for a long time.

The so-called "high-end decoction pieces" and "selling granules with gold" such as Niuhuang, Cordyceps sinensis, Saussurea involucrata, etc. have long been an open secret in the industry, seriously damaging the principle of "openness, fairness and transparency" in drug circulation. Therefore, the centralized collection of traditional Chinese medicine must be implemented as soon as possible. But in the face of many practical difficulties, how to break the game?

The author believes that the key to the breakthrough of centralized collection of traditional Chinese medicine lies in rationalizing the industrial chain by using the big data platform of traditional Chinese medicine industry, and realizing the bottom logic of traditional Chinese medicine products from raw material production, processing, circulation to sales, thus achieving a closed loop.

In this closed-loop front-end, it is an order agriculture based on the concept of blockchain, which is directly linked to the annual orders of demanding enterprises. When the commodity codes are sold out, external capital cannot intervene at all to ensure the stability of supply prices; In the circulation link, it is the two-dimensional code traceability of the whole process; In the sales link, we encourage order agriculture and full traceability with high quality and good price, so that the traceability input of enterprises is worth the money; Finally, basic functions such as standardized warehousing and logistics and third-party testing should be completed.

In this closed-loop system, the construction of big data platform for Chinese medicine industry is very important and is the core grasper. All information such as origin information, product information, price fluctuation, employee data, supply and demand data, quality standards, etc. will be included in this big data platform, and the bottom layer will realize the whole process with unified coding.

Only after the above preparations are completed, can the centralized collection of traditional Chinese medicine have the basis for implementation, and can the original intention of the medical insurance department to raise quality control fees be realized.

I believe that the centralized collection of traditional Chinese medicine will surely make a breakthrough on this basis.

The product strategy of Baidu Zhijia business group can be divided into three major areas: car, road and line: "car" is to provide smart car solutions for B-end car companies; "Road" is an intelligent solution for urban traffic; "Travel" is a travel service for C-end consumers.

On March 14th-16th, 2023, at the 4th Software-Defined Automobile Forum and AUTOSAR China Day in 2023, Wu Changlong, a senior engineer of Baidu Apollo Intelligent Technology Co., Ltd., said that Baidu’s technology accumulation in L4 field and the scale advantage of L2+ products promoted each other, and now it has realized the comprehensive layout of taxi-passenger car-urban transportation. On the technical level, the modular MCU and strong mainline software architecture can meet the needs of parallel development of different models and multiple projects on the same platform; With the support of agile development method and CICD, the output quality can be guaranteed while meeting the rapidly changing internal and external needs.

　

Wu Changlong | Senior Engineer of Baidu Apollo Intelligent Technology Co., Ltd.

The following is a summary of the speech:

Development and challenge of Baidu Apollo intelligent driving domain controller

In the past ten years, Baidu has accumulated rich technology and experience in the field of artificial intelligence, and now it applies these leading AI technologies to the automotive field. The product strategy of Baidu’s intelligent driving business group is laid out in three areas, which are car, road and line.

"Car" refers to the intelligence of cars. ASD, Baidu’s smart car division, is a tier1 role that provides full-stack smart car solutions for B-end car customers, including smart driving and smart cabin. At present, it has provided smart car solutions for 31 car companies, 134 models and more than 7 million cars. Baidu’s car is one of Baidu Apollo’s partners, and will be equipped with the full-stack intelligent solution of Baidu smart car, which will be listed this year.

"Road" refers to smart city traffic. At present, Baidu’s smart city transportation has provided solutions for 63 cities across the country, providing efficiency for urban transportation.

"Travel" refers to providing travel services for C-end consumers, which is known as radish running. Last year, Baidu released the sixth generation RT6, which has the ability to drive automatically on complex urban roads, and its cost reached 250,000 yuan. The mass production of RT6 will greatly accelerate the scale and commercialization of unmanned vehicles.

The above businesses complement each other. Baidu has accumulated rich technology and experience in L4 field, which can provide hot start for L2+ products. L2+ products feed back L4 products with the advantages of scale, and solve the long tail problem of L4 products’ final commercial landing.

Baidu’s smart car products include intelligent driving and intelligent cabin, including small-scale in-vehicle system and software and hardware integrated solution ARC. The intelligent driving domain controller is divided into two heterogeneous control chips, MCU and SOC. MCU deployed AUTOSAR protocol station, and developed CDD and application algorithm on this basis. The bottom layer of SOC is a system, and the top layer is the hardware poke layer and the middleware Apollo OS； developed by Baidu. Further up is the various atomic ability services of the algorithm; Further up are the various application logics of the algorithm.

Next, we will share the challenges we face in the development of intelligent driving domain controller MCU software based on AUTOSAR.

First of all, in recent years, there are many projects of Baidu’s intelligent driving domain controller, and it has already faced the situation that the same hardware platform supports multiple projects and multiple models for parallel development. A project needs to maintain independent software branches, and software changes, software optimization or repairs made in one project branch are always manually migrated to other project branches to ensure the consistency of product experience. And the coupling between software modules is very strong, and the change of one software module will often lead to the change of other modules, which will affect the whole body; In addition, it is necessary to migrate to multiple software branches at the same time, and the workload of maintenance increases exponentially with the increase of software complexity and projects.

In the stage of frequent changes in the demand of intelligent driving track, the time period is very short; However, there will be no reduction in the quality requirements for output. This challenges our software architecture. We urgently need a software architecture that can support multi-project parallel development and rapid iteration.

How to solve this problem? We found inspiration on AUTOSAR. The core idea of AUTOSAR is the decoupling of hardware and software. The bottom layer realizes the software functions that are strongly related to hardware, and abstracts them into standard interfaces for the upper layer. The upper ECU and the application layer are almost insensitive to the difference of the lower hardware, which makes the AUTOSAR architecture software migrate on multiple hardware platforms.

Secondly, the core idea of AUTOSAR is the modularization of software and standardization of interfaces. AUTOSAR is divided into hundreds of software modules, and the function definition of software modules is very clear, and the data between software is exchanged with the defined standardized interfaces. When the software of one module is changed, the influence on other software modules and even the whole controller software is controllable.

Platform of MCU software for intelligent driving domain controller

Our MCU platform software architecture refers to the idea of AUTOSAR. Firstly, a set of loosely coupled software architecture is needed. The so-called loose coupling means software modularization, and the function definition of each software module must be clear. The exchange interface between modules is standardized and managed in a unified file according to the architectural method of AUTOSAR.

The second is the strong mainline software architecture. Referring to the software architecture idea of AUTOSAR, we divide our MCU software into different softwares according to the actual business requirements. A hardware platform has only one software, and a project has a separate software. The interface between is predefined and cannot be easily changed. To ensure that a set of software can be combined with different software of multiple projects.

The actual operation method of this software architecture is:

First of all, the BSW project of AUTOSAR is strongly related to specific projects and models, such as the number of communication buses, the configuration of communication matrix, the configuration of diagnostic protocol stations, the configuration of network management, etc. These configurations are different for each model. Therefore, the BSW engineering code of AUTOSAR is divided into BASE software and CDD software (including IOO abstraction of various hardware and data intervention of sensors, etc.). These modules are only related to the hardware platform and have no direct relationship with the project. The application layer software isolates the differences of signal interfaces of various vehicles through the signal abstraction module, which makes most application layer software project-independent.

In addition, there are some special software modules, such as time synchronization module. All items of the time synchronization scheme in our domain are consistent; However, the cross-domain and vehicle-domain schemes have different projects. For this kind of module, we split the software of a module into two parts for maintenance, provided that the interfaces between the software must be well defined, so that multiple projects can share one software, and different BASE software can work normally together.

Under this software architecture, the methods of software management are different. A hardware platform has only one software warehouse, and each project has a separate BASE software warehouse. Only when the software is merged can the final MCU software output be obtained. Its advantage lies in that the mainline optimization is directly effective for each project. The challenge is how to ensure that the changes on the main line are not wrong for each project, which requires agile development and CICD to ensure.

Agile development of MCU software for intelligent driving domain controller

The software version delivery of the whole intelligent driving domain controller basically follows the traditional automobile micro-model development, from the initial demand input to software design, software development, software testing and overall acceptance, and a version lasts about 2-3 months. In the big cycle, we iteratively split the MCU software version into weekly agile development cycles.

The cycle of agile iteration in weeks can also be refined to the development iteration in days. Baidu has its own set of code management tools. When we push the code, it triggers the continuous integration compilation pipeline to get the compiled results and outputs. At the same time, the system will automatically trigger to pull the latest code from the library every night and push it to the CICD test server. The test server will simulate the upper computer to deploy the software to the domain controller of the test bench, which has a full set of sensor environment and simulated vehicle environment besides the physical domain controller. After the deployment, according to the pre-set test flow, the MCU software is matched with the SOC terminal to conduct a set of systematic tests.

After the test, the server finally collects the test results, and generates an email report and pushes it to the corresponding person. When you go to work the next day, you will know whether there is any problem with the previous day’s cooperation code. In addition to the bench test, we have a lot of driving tests every day, and the data generated in the test and the problems will be uploaded to the data center, and special managers will distribute the problems and data to the corresponding module leaders. After analyzing the data, the R&D personnel locate the problems, and then arrange the repair plan of the problems into the agile iterative process according to the priority, so as to carry out iterative development of the software, quickly deploy the new output to the R&D vehicle, and then carry out closed-loop verification.

At present, automakers pay more and more attention to software self-research, especially in the field of automatic driving. Some automakers choose Baidu as a supplier of software and hardware for intelligent driving systems; At the same time, I hope to participate in the development of some intelligent driving functions.

We also have some successful experiences in the project. First, OEM will generate the document of our intelligent driving domain controller, and then build an algorithm model to generate SWC articles in AR file format. And the final C code will be generated, and the ECU document will be given to Baidu. After we import the AUTOSAR development configuration tool, we can generate the technical engineering of MCU AUTOSAR and develop the software of MCU. Then compile it into a black-box project and give it to the OEM. The OEM will add the black-box project to the code generated by them for integration and compilation. After the compilation is passed, it will do its own module test. After the test is passed, it will give their model code compilation process to Baidu in the form of a black box. Then we will do the final integration, compilation and MCU software output, complete the integration test of the entire MCU domain controller, and deliver the test to the automobile factory, and then do the vehicle-level test.

Wu Changlong’s keynote speech "Software Platformization and Agile Development of Intelligent Drive Controller Based on AUTOSAR" delivered at the 4th Software-Defined Automobile Forum and AUTOSAR China Day in March 14 -16, 2023. )

Special feature of 1905 film network As the youngest "three-gold-winning actress", her film career has always attracted much attention.

In 2023, Zhou Dongyu starred in three works, and for the first time, she played a senior and capable self-media editor, Chen Miao, in her 2023 big screen finale, Hot Search. Her screen image has gradually changed from a girl to a Mesozoic woman, but in the process of her role transformation, the debate of polarized comments has never stopped.

For Zhou Dongyu, Hot Search is a challenge.

In the face of the role transformation debate, she has publicly stated that she did not deliberately transform, and in front of the age of 32, transformation is a natural thing. But in the face of Chen Miao, a capable female role in the workplace, she also regards it as a challenge.

In this challenge of trying to jump out of the comfort zone, Zhou Dongyu first broke through the limitation of her girlish appearance in external conditions, and created the image of women in the workplace through the makeup of wavy curly hair, big red lips and windbreaker; Secondly, she also deliberately lowered her voice to strengthen the maturity and credibility of Chen Miao’s role.

In the aspect of character temperament, Zhou Dongyu actually added an irreplaceable sense of fragmentation to Chen Miao. During the film’s release, there was a hot search for "Zhou Dongyu Chen Miao Shuang Wen’s mistress", and some netizens commented that "Chen Miao’s liveliness is not based on a perfect person’s design, but it is precisely because she is an imperfect rescuer that she is particularly real". As a girl who grew up in an unhappy background in family of origin, Chen Miao’s image is full of arc light.

When Zhou Dongyu plays the role of Chen Miao, the moments when her acting skills can most impress the audience are often those when she reveals fragility, weakness and a sense of fragmentation in the life stage of a mature woman. She is using her best acting skills — — Play the girl’s way, to perform the weak girlhood moments that occasionally flash on mature women. It seems that in breaking the inherent mature label of the workplace, Zhou Dongyu has injected his own personality label.

But many viewers also commented after watching the movie that Zhou Dongyu seemed to be reciting his lines all the time. Indeed, the character Chen Miao is actually running hot news in a large amount of information ocean, facing the constant test of traffic. When Zhou Dongyu, as the editor-in-chief, is reading data and repeating media terms such as "magic bullet theory" and "silent spiral", it is really easy for the audience to play by calmly and mechanically chanting.

Zhou Dongyu himself once said in an interview that one of the biggest difficulties in challenging the role of Chen Miao is to change her girlish voice to adapt to Chen Miao’s mature and professional language expression.

Who is calling for the transformation of Zhou Dongyu?

In the challenge of Zhou Dongyu’s transformation, apart from the audience’s hope to talk to more mature Zhou Dongyu, directors also hope to shoot more Zhou Dongyu.

The director of Hot Search chose Zhou Dongyu to play Chen Miao, just because of the complexity of Zhou Dongyu’s temperament, expecting to portray a new media editor who is both girly and capable enough through the lens.

From this point of view, it is not so much that the market is expecting, but rather that the market is eagerly calling for actresses like Zhou Dongyu to step out of the space of girlish roles and go into the broader spectrum of female roles.

Zhou Dongyu is now a "three-gold actress", and she is irreplaceable as an actress of the same age in terms of awards, the appearance of the film face and even the expressive force of acting.

The audience will mention the transformation, definitely because her previous role has given everyone an excellent "type" cognition, but these three films, represented by Burning Winter, Killing Parrots and Hot Search this year, actually represent a "female stage" that Zhou Dongyu wants to try. She may be a little more mature than a girl, but she is not completely an impeccable and indestructible career in the audience’s cognition.

Zhou Dongyu showed the audience the sense of vulnerability of professional women in Chen Miao’s body in Hot Search. Let the audience see the wandering and confusion of middle-aged women in Nana in Burning Winter; In Killing a Parrot, the audience can also see a woman who has been hurt by her feelings, and her emotional complex texture, and at the last moment, she can also be the one who takes up arms and fights back. In fact, it also adds some rich levels and dimensions to the female roles in film and television works in the market.

For directors or producers, choosing Zhou Dongyu is a icing on the cake. Even if she doesn’t succeed in the transformation, her performance in the film can pass, but if she can create a successful transformation role, the texture of the whole market and the whole film will show a better return on investment.

Therefore, this may also be a wind direction where the industry just chose Zhou Dongyu and expected her to present the transformation characteristics in her own works.

How to take the road of actor transformation?

Zhou Dongyu’s current state and performance can actually provide reference for the market and other actors of the same type.

First of all, the market, the creators must provide more female roles with a richer and broader spectrum for these actors to choose from; Secondly, put it on the actors themselves, and the audience and the market may also hope that they can expand themselves in a wider range and contribute more classic screen images.

Looking back at some examples of successful actresses, for example, when she was about 30 years old, she worked as a film producer, which created a new trend of "chick movies" in mainland China; It was also in his early 30 s that he gained his masterpiece.

So even though there may be some bumps and stumbling in the process of trying, maybe actresses need to make more attempts to adapt upward, so when she chooses a role, her role may grow rapidly with herself.

We also expect Zhou Dongyu, who is standing at the corner intersection and waiting for the traffic lights, to play more beautiful music scores of Mesozoic women on the screen in the future and find the most suitable scale for herself.

　　Beijing, May 29 (Reporter Jing Wong) At 12: 31 on May 28, after a flight of 1 hour and 59 minutes, the flight MU9191 of China Eastern Airlines, which was carried by C919 passenger plane, landed smoothly at Beijing Capital International Airport, passing through the "Watergate" symbolizing the highest etiquette of civil aviation, marking the successful completion of its first commercial flight, officially entering the civil aviation market and opening a new stage of market-oriented operation and industrialization development.

　　This first commercial flight is a milestone from "product" to "commodity" for C919. Guo Qing, an associate professor at the Aviation College of Northwestern Polytechnical University, said in an interview with a reporter from Yangguang. com that the realization of the first commercial flight of C919 boosted the confidence in the development of China’s civil aviation industry, and China’s aviation-related supporting industries will usher in new opportunities.

　　China has officially entered the market competition of world large aircraft production.

　　Large aircraft is known as "the jewel in the industrial crown", which is a concentrated expression of a country’s scientific and technological ability, industrial level and comprehensive strength. "The operation of domestic large aircraft means that China has officially entered the market competition of world large aircraft production, which has made China’s aviation industry move to a higher level." Guo Qing’s analysis also means that in the high-end manufacturing products, China manufacturing can also compete with the world’s large enterprises and stand out from the crowd, which means that the influence of China manufacturing is increasing, which will help to enhance China’s international status.

　　According to "2022 Shanghai Science and Technology Progress Report" issued by Shanghai Science and Technology Commission, by the end of 2022, C919 had accumulated 32 customers and 1035 orders. On April 27th, 2023, HNA Aviation Group and China Commercial Aircraft Corporation signed a purchase agreement for 100 aircraft, including 60 C919 aircraft. Qi Qi, an expert from China Civil Aviation High-quality Development Research Center, told the reporter of Yangguang. com that airlines and leasing companies are extremely optimistic and confident about the commercial market prospects of C919 aircraft, and they are scrambling to sign purchase agreements and strive to get the delivered aircraft and put it into commercial operation earlier.

　　According to Commercial Aeroengine Market Forecast 2021-2040 released by Comac of China, from 2021 to 2040, it is estimated that 41,429 new aircraft will be delivered worldwide, with a value of about 6.1 trillion US dollars. Among them, China aviation market is expected to receive 9,084 passenger planes of 50-seat class or above, accounting for 21.92% of the world, with a value of about 1.4 trillion US dollars, accounting for 22.95% of the world.

　　Qi Qi said that with the commercialization of C919, the trillion-dollar large aircraft industry chain is gaining momentum. "The continuous increase in C919 orders is actually a test of China Commercial Aircraft’s delivery ability, and more specifically, China Commercial Aircraft’s ability to integrate and coordinate the core elements of the C919 industry chain." According to Qi Qi’s analysis, the benefit degree of large aircraft industry chain will be ultimately determined by the annual production capacity and delivery schedule of Comac China. On the basis of ensuring the safe operation and high reliability of aviation, it will be the focus of the next stage to steadily promote and upgrade the localization rate of large aircraft parts, especially core systems and components.

　　Qi Qi believes that the improvement of the localization degree of C919 will fundamentally improve the delivery capacity, stable delivery level and autonomous controllability of Comac China.

　　Orders in related industries such as aircraft supporting manufacturing may surge.

　　After the successful development of C919 large passenger aircraft, customers pay much attention to it. According to reports, according to the international practice of the aviation industry, a model is mature and commercialized on a large scale, and it needs to be continuously optimized and upgraded for many years after entering the commercial operation stage. The reporter learned that in the future, China Eastern Airlines will cooperate with many parties to operate the C919 with high quality and precision, and help make the C919 a successful model recognized by the global industry. "Starting from May 29th, the C919 model will be put into normal operation on the route from Shanghai Hongqiao to Chengdu Tianfu, and with the introduction of this model, the C919 will be put on more routes." Feng Dehua, member of the party group and deputy general manager of China Eastern Airlines, said.

　　Great Wall Securities Research Report believes that, as a representative of high-end manufacturing industry, large aircraft projects have the characteristics of long industrial chain, high correlation and great radiation-driven effect. The development and research of large aircraft projects can effectively promote industrial technology upgrading, promote the process of China’s civil aviation industrialization, and comprehensively promote the development of China’s aviation industrialization.

　　Next, Guo Qing believes that the orders of industries such as metalworking, composite materials, electronic components and chips manufactured by aircraft will surge with the increase of orders of large aircraft. In addition, the education industry will also usher in a "new direction". Aerospace innovation education for young people, aviation majors in colleges and universities, and majors related to industrial chain will all usher in the peak of application, and more young people will devote themselves to China’s large aircraft industrial chain.

On July 18th, the iconic title of "News Network" made a new appearance and the full HD news production and broadcasting was upgraded, which attracted the attention of the industry and society. On the 19th, the 17.6-second video of the first broadcast of "The Challenge of Climbing to the Top is Impossible (Season 5)" also went viral online. Nowadays, the media competition is becoming increasingly fierce. The CCTV integrated channel of the Central Radio and Television General Station is transforming from a traditional TV channel into an all-media communication platform with strong influence.

The viewing data is "bright"

In the first half of this year, the average ratings of integrated channels increased by 8% compared with the same period last year.

　　Scientists discover ferromagnetic quantum critical point evidence for the first time
　　The team of Yuan Huiqiu, a professor at Zhejiang University, discovered the ferromagnetic quantum critical point in pure heavy fermion compounds for the first time, and observed the strange metal behavior. The related results were published online in Nature on March 5. This is the first time that scientists have found conclusive experimental evidence of the existence of quantum critical point in a pure ferromagnetic material system, and observed strange metal behavior similar to that of high-temperature superconductors: when the temperature approaches absolute zero, the low-temperature resistance changes linearly with temperature, and the specific heat coefficient diverges logarithmically with temperature. This discovery breaks the traditional idea that ferromagnetic quantum critical point does not exist, and extends the strange metal behavior to ferromagnetic quantum critical materials, which opens up a new direction for the study of quantum phase transition.
　　Scientists discover accurate diagnosis and treatment of schizophrenia for the first time
　　Biological marker
　　Jiang Tianzai and Liu Bing team of Brain Network Group Research Center of Institute of Automation, China Academy of Sciences, together with researchers from many teams at home and abroad, broke through the bottleneck that the diagnosis and treatment of mental illness only depends on the empirical judgment of symptoms, and successfully established an accurate diagnosis and treatment model of schizophrenia by using multi-group information and artificial intelligence methods. For the first time, the research team found that the abnormal function of the striatum circuit in the brain is a biological marker for the accurate diagnosis and treatment of schizophrenia. Using this biological marker, not only can we quantitatively evaluate the pathological damage of striatum in individual patients, but also can accurately diagnose schizophrenia and predict the individualized curative effect. The imaging marker has been independently verified in patients with mental illness in multiple imaging centers and various populations. The research results were published in Nature-Medicine on March 23rd.

　　Eight "magnifying glasses" relay to simulate the full-scale dark halo clear image of the universe.
　　An international research team led by the National Astronomical Observatory of the Chinese Academy of Sciences adopted a brand-new multiple amplification simulation technology, and obtained a clear image of the internal structure of the full-scale dark halo in the universe for the first time under the current standard cosmological model. The research results were published online in Nature on September 2nd. Dark halo is dark matter halo. It took the researchers five years, with the help of supercomputers, to obtain clear images of dark halos from earth-like mass to giant galaxy clusters, spanning 20 orders of magnitude. It is reported that in a typical area of the universe, this super-magnification simulation needs to be magnified by eight "magnifying glasses", and its magnification is equivalent to finding a flea on a picture of the surface of the moon. The super magnifying glass of computer simulation allows researchers to study the formation, evolution and internal structure of dark halos at different scales in detail. It is found that dark halos with different masses have very similar internal structures, that is, the center is dense and gradually sparse outward. These new findings will help scientists verify the hypothesis about the nature of dark matter-dark matter may not be "completely dark".
　　China’s first superconducting cyclotron was successfully developed.

Original title: Just after the auspicious day of Wen Chang Xi Jun, I have prepared some gift boxes to help me study smartly and attentively, and recommend the Plus version.

In southern Fujian and Taiwan Province, Wen Chang has always been highly regarded, and everyone knows that he is the master in charge of the examination and writing of subjects, and he is a scholar who pays special attention to the title of subjects. The above pictures were taken by me earlier when I visited Wen Kui and Wenchang in Longshan Temple, Taipei, and they were also for the guests who married Wenchang.

Every year, the third day of the second month of the lunar calendar is the spring festival in Wenchang’s ceremony, and it is also one of the particularly good days to read books twice a year.One is on the third day of February, and the other is on the first day of August, which are auspicious days for you in Wenchang.）。

As in previous years, after the Spring Festival in Wenchang, San, in early February of the lunar calendar, some [Wenchang Kui] were also prepared for limited release to fans or their families who need to study more/learn their luck well in the coming year to protect your efforts.

People often ask, who can ask for education?

All kinds of students, company employees, and corporate employees can choose, and try their best to improve their intelligence and study smoothly. In addition to general academic evaluation, industry professional evaluation and workplace rating evaluation can all help (including small university, foreign language, and industry employees’ evaluation)

In the past, old customers always urged me to try my luck. Since it was launched, I have received quite a lot of positive feedback from to be no.1. I will briefly talk about three cases that benefited from Wenchang Daiwei and Wenchang Luojun:

In case A, an old man came to my guest for his own feelings, and he was preoccupied with his nephew’s future. My nephew lingered in the last third of the class before his graduation. At that time, he chose an auspicious time after 1: 00 a.m. to arrange Wenchang for her, but she gritted her teeth and did it anyway. Later, my nephew successfully got a copy.

Editor in charge:

　　International Online News: At present, most schools and grades continue to organize online education and teaching, except for a few senior three and junior three students who report back to school one after another. Many students have become accustomed to the daily life of "online classes".

　　According to Tencent’s latest financial report, since the outbreak of New Crown Pneumonia, QQ home-school group has provided group classroom live broadcast, online tutoring courses and homework management tools for more than 120 million users, helping to carry out online and offline education. In order to provide students with a more focused and efficient learning environment and help minors grow up healthily, QQ has launched a learning mode in the new version, and QQ games have also been officially connected to Tencent Health System in the near future.

　　openQQLearning mode, giving priority to showing learning applications.

　　Users can download the latest version of QQ for iOS (the Android version will be launched soon), and then start the learning mode through Settings-Universal. Learning mode retains the core functions of QQ foundation, and most entertainment and advertising content will be blocked. In the message interface, except "Friends News", "QQ Wallet" and "QQ Security Team", the content push of WeChat official account, subscription number and shopping number is blocked. In the point-of-view and dynamic interface, only learning counseling, simulation questions, homework explanations and other related content and the relevant entrance of learning applications are provided.

　　In addition, in the learning mode, QQ’s home-school group and classmates will show the quick entrance of educational applications, and add functions such as watching online classes and practicing together to provide more learning applications for students.

　　QQ interface

　　In the screen-centered online class world, students’ attention is easily distracted by other Internet information. After starting the learning mode, the overall content of QQ is more focused, which helps students to reduce information interference and improve learning efficiency to the greatest extent.

　　QQSmall games are connected to Tencent Health System to upgrade the protection ability of minors.

　　Recently, QQ games have been officially connected to Tencent Health System, which will help parents to plan the game time of minors and help them grow up healthily through the unified real-name authentication function and the ability of minor users to play and pay. This capability will be realized by the platform, and it is gradually covering all small game users.

　　Users who are certified as minors will not be able to use small game services from 22: 00 to 8: 00 the next day; The legal holidays shall not exceed 3 hours per day, and the other days shall not exceed 1.5 hours per day. At the same time, minor users will also be restricted in the use of paid services, and different age groups will be restricted by different levels of consumption. At the same time, parents can also pay attention to WeChat official account, the "growth guardian platform" in QQ, to control the total duration and consumption of various games played by children, and to guide children to develop healthy playing habits.

　　Resolutely crack down on fraud and ensure the safety of minors online.

　　Combined with the hot spots of online classes, criminals are constantly renovating scam routines, such as sneaking into study groups, changing their nicknames and avatars into the same style as teachers, and defrauding parents and underage students of their money in the name of paying information fees and training fees. For this kind of illegal behavior, QQ security team has continuously upgraded its security strategy and crackdown measures in combination with many years of "black ash production" confrontation experience, "black ash production" big data and AI capabilities, and actively assisted relevant competent authorities to jointly crack down on crimes that endanger network security.

　　According to the statistics of the first quarter of 2020, the QQ security team has blocked the counterfeiters from deceiving their parents about tuition and miscellaneous fees, lurking in more than 6,000 related home-school groups, and protected the property safety of more than 300,000 students and parents. At the same time, the bingo anti-fraud prevention and control system based on Tencent’s years of experience in "black production" confrontation, massive big data and machine algorithms has identified 60,000 fraud warning messages and output them to the police, including 7,000 training fee fraud warning messages. The police have effectively intercepted and dissuaded the victims. In addition, the QQ security team also cooperated with Tenpay Risk Control to intercept fraudulent risk transactions amounting to more than 2.5 billion yuan, including nearly 100 million yuan of training fee fraud.

　　In the face of the internet world with complicated information, helping to protect the healthy growth of minors has always been the direction of QQ. In the scene of online classes, QQ continues to combat prevention through function optimization and related criminal acts, hoping to provide students with a more efficient and safe learning environment and help them better cope with the learning pressures and challenges in a special period.

West Ham United VS Arsenal

After West Ham lost to Everton at home last season, the league suffered two consecutive defeats. The team’s recent performance is really not safe, and it is still difficult to resist when facing the league’s strong teams. At present, it ranks 9 th in the league. West Ham United’s offensive output is acceptable, but the stability of the team’s defense is still insufficient. After Arsenal’s victory over Sheffield United, the league remained unbeaten, and the team is currently ranked second in the league. Arsenal’s offensive output is very strong, and the stability of the defense line is also worthy of praise. Recently, it has been able to score zero opponents in many games.

West Ham United’s overall strength is relatively limited, the team’s recent stability is not high, and the main battle performance is not safe. The Arsenal League has guaranteed unbeaten record so far, and the team’s historical achievements have crushed opponents, so the psychological advantage is very obvious. This time, the team is a guest to challenge their opponents, and I believe that they still have the ability to win from the away game.

Everton VS Burnley

Everton beat West Ham United in the last league. The team’s recent achievements are relatively erratic, showing a plum blossom pile, but its winning ability has indeed improved, and it is currently ranked 15th in the league. Everton’s offensive and defensive ends have also improved to some extent recently. Burnley lost to Bournemouth in the last league, and the league suffered another three-game losing streak. So far, the team has only won one victory, ranking only 19th in the league. Burnley’s offensive output is relatively weak, and the defensive end can be said to be full of loopholes.

Everton’s recent performance is indeed unstable, and the team has no strength against the strong teams, but its winning ability has indeed improved in the face of the weak teams in the league recently. The performance of Burnley, the opponent, continued to be sluggish, and recently suffered a three-game losing streak. This time, Everton is sitting at home to meet the challenge of the weak team, and I believe that I still have the ability to successfully win the opponent at home.

Bournemouth VS Liverpool

Bournemouth defeated Burnley at home in the last league, and finally won the first victory in the league. However, the opponent is really a weak team, and the gold content is really not high. At present, it still ranks 17th in the league. Bournemouth’s front line output is insufficient, and the loopholes at the defense end are not small. Liverpool beat Nottingham Forest at home last season, and the league won two consecutive victories and three unbeaten games. The overall performance of the team has once again strengthened, and it is currently ranked fourth in the league. Liverpool’s offensive output is stable and the defense strength is constantly strengthening.

Bournemouth’s overall strength is very limited, the ability to fight hard is also insufficient, and there is no advantage at home. After all, Liverpool, the rival team, has recently returned to the right track after losing the game unexpectedly, and the stability of both offensive and defensive ends is constantly improving. In addition, Liverpool’s historical achievements have crushed their opponents, and even if they are a guest, they are not afraid.

Manchester United VS Newcastle United

Manchester United lost to the opponent in the last Manchester derby, and was hit by the strong team after winning two consecutive victories. However, the team has won several victories in the near future, and its overall performance has improved. At present, it ranks eighth in the league. Manchester United’s offensive and defensive stability needs to be strengthened. Newcastle United drew away with Wolves in the last league, and the league remained unbeaten in six rounds, but the winning ability was still insufficient, and it is currently ranked sixth in the league. Newcastle United’s offensive output is strong, but the defensive end often has problems.

Manchester United’s domestic and foreign troubles are serious, and the recent achievements and performance of the team are indeed not stable enough. However, as for Chi Hah, he still needs to strive for victory in every game to stabilize the morale of the army. Newcastle United’s overall performance has been stable recently, but its winning ability has indeed declined. In addition, the team’s winning ability in guest games is indeed insufficient. This time, the Red Devils welcomed their opponents at home, and I believe there is still a chance to successfully win their opponents.

Chelsea VS Blackburn

Chelsea lost to brentford at home last season, and the unbeaten game in three rounds of the league ended. Losing the game is really unacceptable, and it is only ranked 11th in the league at present. Chelsea’s offensive output suffered another zero, and the defensive end of the last two league games also lost 2 goals per game. Blackburn lost to Swansea at home in the last league, and its three-game winning streak ended. It is rare for the team to win a winning streak in the near future, and the last game was also ended by opponents. At present, it ranks 12 th in the British Championship. Blackburn’s offensive output is also not stable enough, but fortunately the defense strength has improved recently.

Chelsea’s defeat on the road to the Northern Expedition was indeed a blow to morale, but this time the team ushered in a lower-level league opponent, which was also a rare opportunity for the team to snatch victory and revive morale. Opponent Blackburn rarely won a winning streak recently, but the stability is still insufficient. The last game was terminated by the opponent, and the efficiency of the team’s offensive end really needs to be strengthened. This time, Chelsea played at home to meet the challenge of Championship team Blackburn Rovers. I believe it is not too difficult to win the opponent.

Dortmund VS Hoffenheim

The recent performances of both sides are relatively stable, but Dortmund’s achievements in the past battles have crushed opponents, and their psychological advantages are very obvious. This time, I took a strong home game against my opponent, and I believe I still have the ability to continue my outstanding achievements.

Frejborg VS paderborn

Although Frejborg’s performance is erratic, he has a strong ability to score points in the main battle. Paderborn, the opponent, is a team in the middle reaches of German B, and its overall strength is relatively limited. I’m afraid it’s very difficult to be a guest and challenge Frejborg.

Hertha Berlin VS Mainz

Hertha Berlin’s current situation is erratic, but it is good to win more and lose less, and at the same time, the main battle ability is not weak. Although the opponent Mainz is a high-level league team, the team’s performance so far has not been satisfactory. This time the two sides met, Hertha Berlin still had a chance to defend the unbeaten home.

Udinese VS Cagliari

Udinese’s winning ability is limited, but his recent performance is fairly safe. Although the opponent Cagliari won the first victory in the league in the last campaign, the overall stability is still insufficient, and at the same time, the ability to fight is not good. This time, Udinese is at home, and I believe he still has a certain advantage.
