The writer of this article is @ A Dai of Xiaowan family.

　　The ugly idolize dog is here.

　　Remember the "Do Min Joon" from the stars seven years ago?

　　He’s back with his ABS!

　　Therefore, the new drama was reported as "too large", Xiaowan:? ? ?

　　Speaking of it, as a rare "three-good student" with good acting skills and high popularity, the degree to which Kim Soo Hyun cherishes feathers is staggering.

　　After "You from the Stars" spread all over Asia, the only works he starred in in six years wereA play "The Producer"andA movie "Real".

　　After retiring from the army in July 2019, he was also cautious in the choice of comeback works, and finally took over this "Although it is mental illness, it doesn’t matter" from the beginning of the title of the play.

　　The new drama started on June 20th. After finishing six episodes, Xiaowan couldn’t help but sigh: This brother is so good at choosing scripts!

　　It doesn’t matter though it’s mental illness.

　　The play is produced by Netflix and TvN, and directed by Shin-woo Park who has worked with Cho Jung Seok (Jealousy Avatar) and Park Bo Gum (Boyfriend).

　　But unlike such sweet romantic dramas as Jealousy Avatar and Boyfriend, It doesn’t matter though it’s mental illness.Dark fairy tale love drama.

　　The leading actor, Wen Gangtai (Kim Soo Hyun), is a psychiatric nurse practitioner who has been dealing with various mental patients for ten years.

　　And this is not his biggest burden: Wen Gang’s parents died when he was too young, and he lived alone with his autistic brother.Taking care of his brother is his "reason to live".

　　Gentle and restrained, coupled with rough life experience, the "angel-like" Wengangtai always gains the pity and care of the people around him, and his life can be regarded as bitter but warm.

　　The heroine, Gao Wenying (Seo Yea Ji), is completely the opposite of Mrs. Wen Gang: she is a popular fairy tale writer, rich and popular, and everywhere she goes, she is full of stars.

　　But because of suffering fromAntisocial personality disorderCoupled with the shadow left by his father’s violence and his mother’s suicide when he was a child, Gao Wenying developed a defiant, arrogant and reckless style.A "witch" who pursues extreme egoism to the end.

　　Angels and witches meet unexpectedly, so it’s meant to be, right?

　　No, it doesn’t matter if it’s mental illness.Two disabled people heal each other.The story.

　　Pay attention to personality defect groupsThe setting of+the highly anticipated Cass, this drama was not unexpectedly one of the ratings in the same period on the opening day.

　　On the day of the premiere, the female host’s exquisite makeup and high-cold gas field were eye-catching, and the male host also brushed a wave of heat through the abdominal muscles.

　　However, with the deepening of the plot, the characters of Wen Gang Tai and Gao Wenying and the long story formed by this character have become a greater motivation for the audience to follow the drama.

　　Gao Wenying’s "abnormality" can be seen at a glance.Anti-social personality disorder makes her unable to communicate with people normally, arrogant and rude, and her language is vulgar.

　　At the beginning of the series, she directly explained her experience with a Gothic animation: she was imprisoned as a monster since she was a child, with no friends and no freedom.

　　And her fairy tales are alsoDark fairy tale style with cruel words and bloody illustrationsAlthough it is very popular, it is often on the verge of "no sale".

　　After getting to know Mrs. Wen Gang, a nurse, Mrs. Wen Gang will often comfort her emotions and help her calm down in a professional way when she is rude and violent.

　　Because of the relationship between the patient and nurse practitioner, the audience will initially think that the "mental illness" in the title refers to the heroine Gao Wenying.

　　But as a "patient", Gao Wenying has her own way of relieving:Every work of hers tells her own story.

　　Speaking of the dark past and accepting it, Gao Wenying has taken the first step of "healing".

　　In addition to the autistic brother who is receiving treatment and the anti-social personality woman who is self-resolving, Kim Soo Hyun playsWengangtai is the "patient" who hides the deepest.

　　Because my brother is autistic, Mrs. Wen Gang was asked to take care of and protect her brother from an early age.

　　Mother will even look Wen Gangtai directly in the eyes and tell him:I wanted someone to take care of my brother, so I gave birth to you.

　　Wen Gang, who was born because he was useful, was taught to live for his brother since he was a child, and only his brother’s mother let him.Accustomed to suppressing one’s emotions and desires..

　　For more than ten years, I have been circling around my brother, which has made him a typical paying and even flattering personality.

　　After his mother died unexpectedly, Mrs. Wen Gangtai was left with her brother, who could not perceive emotions. He tried to teach him to judge others’ emotions through expressions: what is happiness, what is anger, what is disappointment …

　　Because my brother learned to read and read, over time, Mrs. Wengang would habitually smile as long as she faced her brother. He said, "It’s not hard to smile at people anyway.”。

　　Having lived with my brother for a long time, and having a professional nurse practitioner qualification certificate, such Wen Gang seems to be very good at dealing with people with mental/mental state deficiency.

　　But in fact, from childhood, he failed to learn to talk to himself and how to express himself correctly.

　　Wen Gangtai is also a "patient". He doesn’t know how to love himself.

　　As his friend Jae-soo said: You laugh like a clown.

　　One sentence tells the real life and psychological state of Wengang.

　　On the surface, one of them is an angel and the other is a witch.

　　In the previous episodes, the painting styles of Wen Gang Tai and Gao Wenying in the play are also two extremes:

　　The man lives in poverty and his brother is ill, but the company of his brother and friends fills his side with a dull and warm atmosphere;

　　The scene in which the heroine appeared alone turned into a horror suspense film in seconds, with arrogance during the day and nightmares at night, which was completely miserable.

　　But just like BGM’s lyrics, "You breathe in my body and pour out your thoughts; I lost everything and breathed in your shadow. "

　　The spiritual world of Wen Gang Tai and Gao Wenying is actually two sides of the same coin set in "Although it is mental illness, it doesn’t matter".

　　They represent the two extremes of human inner feelings, and they are all eager for the other side of themselves, so they will attract each other and get closer and closer.

　　So this drama is actually aboutAngels and witches attract each other, heal each other, and finally become human beings.The process.

　　This process is actually quite cruel.It is extremely difficult to admit that you are missing and need to be cured.That’s why society is afraid to avoid "mental hospitals" and "mental patients".

　　Therefore, the whole drama "It doesn’t matter although it’s mental illness" is trying toCreate a "divorced from reality" atmosphere.

　　The world in the eyes of autistic brothers is a world that will interact with themselves like cartoons.The model in the window will wave, the clouds on the mural will glow, and everything in the world will change rapidly with his mood;

　　The lights in the mental hospital are always flickering, and the patients’ various auditory hallucinations are shaped into a horror film atmosphere;

　　Gao Wenying’s castle is like a fairy tale with dark style. The witch and princess live in the world at the end of the forest …

　　This aspect is presenting what we often say.Psychopaths’ own world",give the audience a direct impact.

　　On the other hand, these seemingly incompatible environments are actually revealing the final direction of the play:

　　All this is true. There are always people who live like this.

　　As for how to peel off the layers of fog and disguise to see the truth, "Although it’s mental illness, it doesn’t matter" also gives the answer:

　　There are a lot of close-ups of faces and even partial close-ups of eyes in this play.

　　Do you still remember Mrs. Wen Gangtai’s training for autistic brothers? Expression can judge people’s mood.

　　Even if the expression can be disguised, the true inner emotions will be revealed through the eyes.

On the morning of February 3rd, under the guidance of Sichuan Provincial Department of Commerce and sponsored by Meishan Municipal Bureau of Commerce and Dongpo District Government of Meishan City, "Weimei Sichuan Xiangpiao Dongpo" 2023 Meishan Food Activity and Meizhou Famous Chef Award Ceremony were held in Impression Water Street of Dongpo, Meishan, which also marked the official launch of 2023 Meishan Food Activity.

The event lasted from February 3rd to February 5th (Lantern Festival on the 15th day of the first month). During the event, hundreds of food merchants were attracted to participate. The products included Tianfu famous dishes, Dongpo famous dishes, non-legacy foods, special snacks, innovative products, rich American foods and high quality and low price.

In the past, the hebang cuisine in Sichuan cuisine refers to the food taste along the Minjiang River. How to connect the cities along the Minjiang River into a modern food corridor? On the same day, the food industry associations in Chengdu, Meishan, Deyang, Ziyang and Leshan signed a strategic cooperation agreement to jointly build a "Minjiang Food Corridor in Metropolitan Area", which will rely on the opportunity of the urbanization development of Chengde Meizi to strengthen cooperation and exchange and innovative research and development of dishes, jointly inherit Sichuan cuisine culture and develop Tianfu cuisine. The event also publicized the local standards of Dongpo cuisine in Sichuan Province (Meishan City).

In recent years, Meishan City has adhered to the "Meishan Excellent Talents Project" as the overall plan, gradually implemented the Meizhou local talents cultivation plan, carried out the cultivation and selection of Meizhou famous craftsmen and Meizhou famous chefs, and awarded the second batch of Meizhou famous chefs. (Bai Yang reporter Zhang Meng)

After a lapse of one year, on May 15th, the US government once again used state power to block Huawei. Compared with the impact of last year’s "516 entity list", this attack is more accurate and thorough.

To put it simply, if any semiconductor company in the world wants to produce chips for Huawei, it needs to obtain permission from the United States first.

Why can the US government be so lenient? Because every semiconductor company in the world is using the software and technology of American companies more or less. This is the so-called "long arm jurisdiction".

Are semiconductor enterprises in China bound by this? Theoretically, this is the case, because some underlying technologies in China’s semiconductor industry chain can only adopt American technologies.

The United States’ comprehensive restriction and upgrading of Huawei’s chip industry covers the upstream software of chip design, the upstream equipment of chip manufacturing and the 7nm chip manufacturing mainly produced by TSMC. The US Department of Commerce has carried out a fixed-point precision strike on all links of Huawei’s chip industry chain.

The first thing is the upstream EDA software of chip design. Although Huawei can design chips, the high-end software EDA tools for IC design are still basically monopolized by three American companies: Cadence, Synopsys and Mentor. In the China market, these three EDA software companies occupy 95% market share.

As far as Huawei is concerned, since May 16 last year, the cooperation between the three major EDA manufacturers in the United States and Huawei has been terminated. This means that Huawei has not obtained new tools and new upgrade services since then, but it can continue to use EDA tools that Huawei has purchased and authorized. In other words, at present, Huawei Hisilicon can also use the old version of EDA for IC design.

However, in the long run, the localization of EDA software is imperative. Some analysts believe that the technical restrictions in the United States are bringing opportunities to the development of domestic EDA software in China.

Having said that, we must also be soberly aware of the technical gap between China and the United States in EDA software and the difficulty of domestic substitution. But at the same time, we should give up the illusion of "compromise and surrender" and seek the possibility of technological breakthrough.

Why is EDA software important?

If chip manufacturing is compared to building a building, IC design is the design drawing of the building, and EDA software is the design tool of this drawing, but the complexity of EDA software is n orders of magnitude higher than that of architectural design software.

EDA, the abbreviation of Electronics Design Automation, is a computer-aided design software system developed on the basis of electronic CAD technology, which integrates the latest achievements of applied electronic technology, computer technology, information processing and intelligent technology to automatically design electronic products.

Using EDA tools, electronic designers can design electronic systems from concepts, algorithms, protocols, etc., and can automatically process the whole process of electronic products from circuit design, performance analysis to designing IC layout or PCB layout on the computer. EDA technology can be widely used in many fields such as electronics, communication, aerospace, machinery and so on.

With the development of integrated circuit technology, EDA software is more and more synonymous with "chip design software tools" by the industry.

That is to say, EDA software is an important tool for chip design. However, due to the complex technology, fine division of labor and multi-technology synthesis of chip design, EDA software does not refer to only one or several softwares, but involves nearly a hundred different technologies and covers a variety of "point tools" software tool clusters.

EDA software can greatly improve the efficiency of chip design, and also has applications in chip manufacturing, packaging and testing. EDA, semiconductor materials and equipment together constitute the three foundations of integrated circuits.

Today, there are at least hundreds of millions to billions of transistors on a chip, and continuous simulation and verification are needed in the design process, which are inseparable from EDA software. Without EDA tools, no matter how high the level of chip designers is, there is no place for them.

From the basic role of EDA in chip design and manufacturing, its importance is self-evident; From the complexity of EDA software, its technical realization is very difficult.

Specifically, the front-end design of the chip includes chip specification formulation and detailed design, HDL coding, simulation verification, logic synthesis, static timing analysis (SAT) and formal verification. The back-end design includes DFT, FloorPlan, clock tree synthesis (CTS), Place & Route, parasitic parameter extraction, physical verification of layout and so on … …

Judging from the tools used in these design processes, it is almost monopolized by three American companies, Cadence, Synopsys and Mentor, which may disappoint many people who call for the localization of EDA software as soon as possible.

So, what challenges does the domestic substitution of EDA in China face?

What are the difficulties faced by EDA localization substitution?

We must first understand the characteristics of EDA industry. EDA is an extremely important key link in the integrated circuit industry chain, but it is also a highly centralized industrial link with relatively small output value.

In 2018, compared with the chip industry of nearly 500 billion US dollars, the market size of the whole EDA is only 9.715 billion US dollars. Among them, 70% of the market share is occupied by EDA giants Synopsys, Cadence and Mentor Graphics under Siemens. The global EDA industry has formed an oligopoly pattern of the three giants. In the China market, the three giants account for more than 95% of the EDA market share, with a higher concentration.

This has not only greatly squeezed the development space of China’s EDA industry, but also seriously affected the pace of domestic research and development of EDA software in China. In the 1990s, when the United States lifted the ban on EDA in China, the advanced EDA software from the United States quickly came to China, attacking the city all the way, which disrupted the pace of independent research and development of EDA in China, and "market for technology" became the path dependence for the next decade.

Compared with American high-end and mature EDA industrial chain, what are the difficulties in the development of EDA industry in China?

The first is the technical threshold. EDA tool is a "multi-tool" software cluster. At present, Chinese enterprises have achieved breakthroughs in some tools, but at present, more technology needs to be accumulated in the complete and available full-process tool chain, which cannot be completed in a short time.

Secondly, the technology integration is high. EDA is the result of long-term cooperation among chip design companies, fabs and EDA software vendors, which requires a lot of talent investment, mathematical optimization and experience accumulation, and cannot be achieved overnight. At present, many EDA enterprises not only provide EDA software, but also provide IP design, which can not only reduce costs, but also improve IP quality by developing some customized EDA functions, and become the main popular mode at present. Our country’s integrated design ability in advanced process is obviously behind the foreign 2-3 generations.

Once again, it is the talent threshold. In terms of EDA software R&D talents, there are not many universities in China that set up EDA majors, and the Internet and financial industries attract a large number of software development talents, which leads to a serious shortage of EDA software R&D talents.

Finally, China also needs to strengthen the intellectual property protection of EDA technology.

At present, EDA has become the key bottleneck for China’s semiconductor industry to achieve autonomous control. In the field of EDA software, China has owned enterprises such as Huada Jiutian, Guangliwei, Xinhe Technology, Lanhaiwei, Jiutongwei, Bodawei, Jilun Electronics, Kejingda, Chuanglian Zhiruan, etc. It is necessary to achieve a comprehensive breakthrough from "point" to "surface" in overcoming the above problems.

How to break the situation of EDA software localization replacement?

Let’s look at the current situation first. Before the 516 entity list incident last year, Huawei obtained the permanent authorization of EDA tools at that time. Because these EDA software can lead the actual chip manufacturing process for two or three years, the EDA ban will not have much impact on Huawei’s chip design in the short term.

However, if Huawei can’t get the updated and upgraded EDA tools because of the continuous technology export ban, it will greatly restrict Huawei’s iterative development in higher-end chip technology.

Not long ago, Huawei tried to design chips jointly with stmicroelectronics (STM.N). One of its purposes was to obtain EDA design technology to find technology records beyond the US technology ban. However, with the intensification of this round of sanctions, this cooperation may also be terminated.

At present, Huawei can only transfer 14nm chip manufacturing orders to domestic SMIC. In the manufacturing of 5nm and 7nm chips, SMIC still lags behind TSMC’s technology and process. One of the big reasons is that domestic manufacturers who provide chip design software for SMIC cannot achieve a breakthrough in the design of high-end chips.

In the long run, it is imperative to replace EDA software in China. The new round of technical restrictions in the United States has strengthened the determination and speed of China’s semiconductor industry’s autonomy. And a series of factors are also quietly promoting the development and break of EDA software industry in China.

First of all, the leading EDA enterprises in China are receiving a number of grants and strategic investments from the state and investment institutions.

On the evening of May 15th, SMIC announced that the second phase of the State Integrated Circuit Fund and the second phase of the Shanghai Integrated Circuit Fund had injected US$ 1.5 billion and US$ 750 million into SMIC South respectively. This will greatly expand the production capacity of 14 nm wafers.

Similarly, the country is also increasing the resource inclination of EDA industry and promoting the independent development of EDA software. Among them, Guowei Shenzhen’s special sub-project "Development and Application of EDA System in Chip Design Whole Process" ("the project") has been approved by the national major science and technology special project, and will receive a total of about 400 million yuan from the project. As the largest EDA company in China, Huada Jiutian has also received several rounds of investment of several hundred million yuan from various investment institutions in China in recent years.

In terms of policy support, in the face of the situation that domestic EDA software is not used, domestic EDA software is given a certain purchasing inclination. For example, the "Several Measures on Accelerating the Development of Integrated Circuit Industry" issued by Shenzhen recently introduced the first domestic policy to explicitly support EDA R&D, including funding incentives for EDA R&D and subsidies for purchasing domestic EDA software.

Secondly, at the market level, the new development of domestic IC industry also brings some opportunities for the development of domestic EDA software.

At present, new technologies such as 12nm and 7nm are widely used in domestic chips, which urgently requires domestic EDA software to develop products comparable to international manufacturers. Only in the design based on the most advanced technology, it is possible to find the defects of the process and potential product opportunities. Of course, this poses a certain challenge to domestic IC design enterprises, but in the case that the United States can "get stuck" at any time, we must pay some trial and error costs to promote the progress of domestic EDA software.

The rise of new applications such as AI chips and IoT chips has brought new challenges to the existing EDA industry and chip design process, and also brought many new technical research directions to small and medium-sized EDA companies, which has become a new opportunity for them to break through the barriers of EDA giants.

Thirdly, AI technology, as a new variable, is bringing a breakthrough to domestic IC design.

Recently, Google is using AI algorithm to learn the layout of chips, so that products beyond manual design can be designed in a shorter time. Similarly, AI technology is being widely used in EDA companies. For example, Empyrean Mcfly, which was launched by Huada Nine Days ago, uses AI algorithm to accelerate IP verification, and uses AI to learn previous IP cases to verify the new IP, and the verification accuracy reaches about 99%.

In addition, if we want to look at the "broken core" incident in the United States from a longer-term perspective, we must realize that perfect property rights protection of technological innovation and mature talent training mechanism are the fundamental ways for China to achieve core technology in its own hands.

Finally, we should realize calmly that the domestic substitution of EDA software and other related core technologies in chip manufacturing is definitely not a natural thing. Think about the prosperity and decline of Japanese semiconductors, which is our lesson.

In the short term, the prohibition of existing foreign EDA software will not have a fatal impact on Huawei, but Huawei is facing a more dangerous situation because of the upgrade of the entire semiconductor technology in the United States. Actively playing games and seeking "spare tires" have become two preparations to be carried out at the same time.

In the long run, the country and the industry can no longer have the illusion of "compromise" and "seeking to let go" of the United States. All sectors of the industry must show patience and determination to invest in the development and research of basic science and core technologies.

On this more difficult road, China’s chip industry and related science and technology industries should be prepared for long-term suffering. This is especially true for EDA software industry.

　　At 6: 52 on May 14th this year, the C919 passenger plane numbered B-001J took off from the fourth runway of Shanghai Pudong Airport and landed safely at 9: 54, marking the successful completion of the first flight test of the first C919 passenger plane that China Commercial Aircraft Corporation will deliver to its first customer.

　　Xinhua News Agency reporter Ding Ting photo

　　General Secretary of the Supreme Leader said that making the China big plane soar in the blue sky bears the national will, national dream and people’s expectation.

　　On September 29th, the Civil Aviation Administration of China awarded the C919 type certificate to Commercial Aircraft Corporation of China (hereinafter referred to as "Comac China"). From the establishment of the project in 2007 to the first flight in 2017, and then to the completion of evidence collection, it took 15 years, and the domestic large aircraft was finally allowed to engage in commercial operations and was about to soar above the blue sky.

　　What are the advantages of domestic large aircraft? Why build your own large civil aircraft? Our reporter interviewed Comac China and relevant experts in civil aviation.

　　Have a competitive advantage in many aspects

　　— — It is not only equipped with advanced systems and materials, but also provides passengers with a more comfortable ride environment.

　　On September 29th, the type certificate certification ceremony of C919 aircraft was held in Beijing Capital International Airport, which was an important milestone in the cause of China’s large aircraft, and marked that the large passenger aircraft with independent intellectual property rights developed by China in accordance with internationally accepted airworthiness standards passed the airworthiness certification. Since then, China has a single-aisle trunk airliner that can be put into operation.

　　"C919 completed the evidence collection, indicating that its safety and reliability meet the requirements of airworthiness regulations." Li Xiaojin, director of civil aviation university of china Institute of Aviation Economics, told this reporter that the C919 successfully made its first flight in May 2017. During the flight test period of more than five years, six trial aircraft have completed a series of flight test missions in Yanliang, Shaanxi, Nanchang, Shandong, Pudong, and Dunhuang, Gansu, and comprehensively verified the power and electrical systems, verifying the safety and reliability of the aircraft in various extreme situations such as stall, natural icing, high temperature and extreme cold. At 6: 52 on May 14th this year, the seventh aircraft of C919 jumbo took off from Shanghai Pudong Airport and landed safely at 9: 54, marking the successful completion of the first flight test of the first C919 jumbo aircraft that China Commercial Aircraft Corporation is about to deliver to its first customer.

　　Whether a civil airliner can be put into commercial operation is not decided by the manufacturer, nor by the operator, that is, the airline, but by airworthiness certification. The type certificate won this time is the ticket for large aircraft to enter the aviation market.

　　After getting the admission ticket, it depends on the advantages of domestic large aircraft if they want to gain a foothold in the aviation market.

　　C919 is equipped with advanced systems and advanced materials. According to Comac of China, the C919 wing design adopts supercritical airfoil design independently developed, which can reduce drag by 5%. The use of advanced materials such as Al-Li alloy and composite materials makes the structure lighter, which greatly improves the safety, economy and environmental protection of the aircraft. At the same time, it is equipped with advanced airborne systems and engines with superior performance.

　　For passengers, the wide fuselage of the C919 will provide more seating space. At the same time, it adopts high-efficiency air filtration system to provide passengers with high-quality fresh air, and the cabin lighting adopts humanized scene lighting design to create a warm and considerate comfortable environment.

　　The C919 is aimed at Airbus A320 and Boeing 737 series models, and adopts single-channel narrow-body layout, with 158 to 192 seats and a range of 4,075 to 5,555 kilometers. At the same time, the C919 is safe and reliable, backed by the vast China market, and has unlimited potential.

　　At present, C919 has accumulated more than 800 orders from 28 customers. "Before type certificate was acquired, there were more than 800 orders, which was quite impressive. The safety, economy, comfort and other aspects of the C919 are relatively suitable for market demand, and are suitable for domestic long-distance routes and neighboring Southeast Asian international routes. " Li Xiaojin commented like this.

　　An important milestone in China’s commercial aircraft manufacturing industry

　　— — It is a large jet civil aircraft developed by China and with independent intellectual property rights.

　　Why build a large domestic civil aircraft? Aviation manufacturing industry is known as the "flower of industry", with long industrial chain and high added value, involving hundreds of professional categories, which has high requirements for industrial capacity. Among them, the R&D and manufacturing capacity of large passenger aircraft is an important symbol of a country’s aviation manufacturing level and is also regarded as the embodiment of a country’s overall strength.

　　In the past ten years, the C919 research team insisted on independent innovation and open cooperation, successively conquered a number of key technologies, formed a number of core capabilities, tempered a number of talent teams, promoted a number of industrial development, and formed a capability platform to support the independent development of China large aircraft.

　　The person in charge of Comac China said that through the development of C919 large passenger aircraft, China has completed the whole process of design, manufacture, test, flight test and airworthiness certification for the first time, and has the ability to develop large passenger aircraft according to internationally accepted airworthiness standards.

　　C919 adopts the mode of "main manufacturer+supplier". As the main manufacturer of domestic large aircraft, Comac China is responsible for the design and development, system integration, final assembly, airworthiness certification, customer service and marketing of C919. Comac China conducts supplier selection and management for airframe structure and airborne system equipment nationwide. The structure of C919 is designed by Comac of China, and manufactured by many domestic enterprises, with completely independent intellectual property rights. The engine is provided by CFM, a US-France joint venture company, and the avionics system is provided by Angji Avionics, a Sino-US joint venture company.

　　The development of domestic large aircraft is also an important aspect to meet the dual needs of the national economy and development strategy. Li Xiaojin said: "The civil aviation industry is a national basic and strategic industry. Buying a large number of foreign aircraft makes our air transportation industry subject to people. At the same time, the price of Airbus A320 and Boeing 737 series aircraft is about $110 million to $120 million. If you buy hundreds of aircraft every year, it will cost tens of billions of dollars, which is relatively high. With the commercial operation of C919, it will accelerate the integration of upstream and downstream industries, amplify the industrial correlation effect of civil aviation and aviation manufacturing, and further improve the overall economic development quality. "

　　The aviation market in China is large.

　　— — In the next 20 years, China’s demand for passenger airliners is estimated to be 9,084, worth about 1.39 trillion US dollars.

　　At present, Airbus and Boeing account for the bulk of the global civil aviation aircraft market with more than 100 passengers. After C919 is put into commercial operation, what impact will China large aircraft bring to civil aviation?

　　— — Create new economic growth points.

　　China’s civil aviation transportation industry is in a period of rapid growth, and the domestic market demand is great. The development of domestic large aircraft will better meet the needs of China’s economic development and people’s travel, and create new economic growth points.

　　China Commercial Aircraft Corporation Market Forecast Annual Report (2021— 2040) predicts that in the next 20 years, more than 41,429 new aircraft will be delivered worldwide, with a value of about 6.1 trillion US dollars (based on the 2020 catalogue price). China aviation market will receive 9,084 new aircraft, with a value of about 1.39 trillion US dollars (based on the catalogue price in 2020). Among the newly accepted aircraft in China aviation market, the number of narrow-body passenger aircraft will reach 6,295. As the mainstream aircraft in the civil aviation transportation market, narrow-body passenger aircraft account for about 80% of China’s civil aviation fleet and 70% of the global fleet.

　　— — Promote the upgrading and development of the industrial chain.

　　C919 is the take-off work of China’s large civil aircraft industry, and the aviation manufacturing industry chain driven by C919 has great potential. It is expected that it will drive group breakthroughs in new materials, modern manufacturing, advanced power, electronic information, automatic control, computers and other fields, and will also enable aviation high-end raw materials, subsystems and parts manufacturers to achieve performance growth. At present, more than 20 provinces, more than 1,000 enterprises and institutions and nearly 300,000 people have participated in the research and development.

　　Taking materials as an example, the application of new materials is an important aspect of the development and progress of aviation technology. The manufacturing of large civil aircraft involves composite materials, titanium alloys, high-strength steel, etc. The development of C919, and a variety of new materials are applied to civil aircraft on a large scale for the first time, which not only leads to a breakthrough in material technology, but also brings great demand to the material industry.

　　The successful development of C919 will provide more choices for airlines and customers, more opportunities for suppliers and partners, and further stimulate the healthy competition and innovation vitality of the global commercial aircraft industry.

　　The airworthiness certification is only the first step for C919 to be put into operation, and the subsequent industrialization will take a long time. Li Xiaojin said: "According to public data, there are about 50,000 transport aircraft in operation around the world, of which Boeing and Airbus each account for about 45%. In the future, C919 should also strive for the european aviation safety agency airworthiness certificate and the US Federal Aviation Administration airworthiness certificate in order to put it into commercial operation in more countries. " He said that there is still a gap between China and the world-class level in aero-engine manufacturing and avionics system design. Compared with automobile and other industries, the aviation manufacturing industry has the characteristics of high technology added value and low labor intensity, and there are certain technical barriers. The technology in many sub-sectors of the industrial chain still needs to achieve a breakthrough from 0 to 1.

　　Slow and steady, with unlimited potential, China Big Aircraft will write more wonderful stories.

　　Agricultural brand is an important symbol of agricultural and rural modernization, and cultivating and developing agricultural brand is an important starting point for comprehensively promoting rural revitalization and accelerating the construction of an agricultural power. In 2022, the Ministry of Agriculture and Rural Affairs issued the "Excellent Agricultural Brand Cultivation Plan (2022-2025)", which defined the objectives, tasks and measures for strengthening agricultural brands. In 2023, the No.1 Document of the Central Committee proposed to support poverty-stricken areas to build regional public brands. In this issue, invited experts will discuss issues related to brand strengthening agriculture.

　　Actively cultivate agricultural brands

　　What is the current development of agricultural brands in China?

　　Hu Glacier (Director and Researcher, Agricultural Products Trade and Policy Research Office, Institute of Rural Development, China Academy of Social Sciences): Agricultural brand building is an important measure to promote the high-quality development of agriculture. Cultivating and developing agricultural brands is conducive to improving the modernization level of the whole agricultural industry chain, guiding the gathering of high-quality resources, and promoting the optimization and upgrading of industrial structure, which is an important way to increase farmers’ income and enhance agricultural competitiveness.

　　In recent years, the state has issued a series of policies and measures around building agricultural brands. In 2022, the No.1 Document of the Central Committee proposed to carry out the actions of improving agricultural varieties, improving quality, building brands and improving standardized production. In 2023, the No.1 Document of the Central Committee proposed to support poverty-stricken areas to build regional public brands. In April this year, the General Office of the Ministry of Agriculture and Rural Affairs issued the "Implementation Plan for Supporting Poverty-stricken Areas to Build Regional Public Brands (2023-2025)", emphasizing the efforts to build regional public brands in poverty-stricken areas and promoting the effective connection between consolidating and expanding poverty-stricken achievements and rural revitalization.

　　All localities actively cultivate agricultural brands in light of their own reality. For example, Heilongjiang Province, as a major agricultural province, has made great efforts to build a provincial-level high-quality agricultural brand with "excellent black soil", build a "1141" agricultural brand system and build a life-cycle agricultural brand management mechanism. In order to strengthen the construction of agricultural brands and establish and improve the mechanism of cultivation, development and protection of agricultural brands, Hainan Province has promoted the establishment of an agricultural brand catalogue system.

　　Agricultural brands have achieved practical results in promoting the quality and efficiency of agricultural industries. According to estimates, compared with 2012, in 2022, the output of public brand agricultural products in China agricultural brand catalogue area increased by nearly 55%, and the sales increased by nearly 80%, driving the income of local farmers to increase by 65%. From the current development of agricultural brands in China, it has the following characteristics.

　　First, regional public brands, corporate brands and product brands have developed rapidly. According to the data of the Ministry of Agriculture and Rural Affairs, in recent years, agricultural and rural departments at all levels have further promoted brand strengthening agriculture and cultivated a number of influential agricultural brands. By the end of 2021, about 3,000 regional public brands, 5,100 enterprise brands and 6,500 product brands have been cultivated by provincial agricultural and rural departments. According to relevant reports, Wuchang Rice, as a regional public brand, has a brand value of 71.31 billion yuan in 2023.

　　Second, the cultivation of agricultural brand products and brand assistance have achieved results. The "Excellent Agricultural Brand Cultivation Plan (2022-2025)" proposes that by 2025, we will focus on grain and oil, fruits and vegetables, tea, animal husbandry, aquatic products and other categories, build a number of regional public brands of agricultural products with excellent quality, distinctive features, strong driving force, high reputation and consumer loyalty, and cultivate and promote a number of enterprise brands and high-quality features with excellent products, good reputation, obvious industrial driving effect and core competitiveness. In 2022, 75 brands including Wuchang Rice, Enshi Potato, Luochuan Apple, Wenchang Chicken and jinxiang garlic were included in the agricultural brand quality cultivation plan, and 69 brands were included this year. In terms of agricultural brand assistance in poverty-stricken areas, by the end of 2022, the Ministry of Agriculture and Rural Affairs had taken the lead in helping 20 key counties, and the average premium of branded agricultural products in poverty-stricken areas exceeded 20%.

　　Third, the variety, quality and brand of agricultural products are integrated with each other. In the process of agricultural and rural economic development, the rapid growth of corporate brands has brought about market segmentation, which often reflects the quality differences in the early days. In recent years, with the continuous emergence of new crop varieties, the protection of intellectual property rights has gradually increased, and more and more new varieties are deeply bound to brands. For example, in 2022, many new corn varieties such as "Denghai 2035", "Denghai 2052" and "Denghai 2056" independently developed by Denghai Seed Industry passed the examination and approval, and "Denghai" became the brand prefix of crop varieties.

　　Fourth, the ability of brand marketing and promotion has been improved, and the speed of brand renewal has been greatly accelerated. With the help of the Internet, agricultural brands promote consumer reach and sales through digital marketing. With the help of well-known exhibitions and other platforms at home and abroad, the promotion efforts have been intensified, and various channels such as video and live broadcast have been used to enhance the communication power. High-quality agricultural products have been sought after more and more, and new agricultural brands have begun to emerge, including many emerging, innovative and differentiated agricultural brands. For example, Xuwen pineapple, fire crystal persimmon and other high-quality agricultural products quickly became popular. Cultivating agricultural brands needs to consider long-term value, which also requires building a comprehensive brand development strategy.

　　Fifth, the brand participation of consumers continues to increase. In the traditional sense, consumers’ contribution and participation to the brand depends on factors such as culture and habits. However, with the development of mobile Internet, more and more consumers’ feedback has been absorbed into the cultivation and development of agricultural brands. The relationship between agricultural brand cultivation and consumer feedback is getting closer and closer. Some consumers directly send the design drawings of product packaging and brand to manufacturers through short videos, and some consumers participate in brand promotion through media.

　　We should also see that at present, there are still many problems in China’s agricultural brands, such as excessive but not refined, large but not strong, and brand influence needs to be improved, which is also the focus of brand promotion in the future. With the improvement of the level of economic and social development, more and more excellent agricultural brands will come to the fore, constantly meeting the people’s growing needs for a better life.

　　Help improve agricultural quality and increase farmers’ income

　　What is the role of agricultural brands in promoting agricultural quality and efficiency and increasing farmers’ income?

　　Liu Naiyong (researcher, National Agricultural Market Research Center, China Agricultural University): In recent years, China’s agricultural brands have mushroomed, which not only allows consumers to enjoy more high-quality agricultural products, but also plays a significant role in promoting the high-quality development of agricultural industries and increasing farmers’ income.

　　First of all, agricultural brand building has promoted the development of agricultural industry standardization. Agricultural products have natural non-standardized characteristics, and coupled with a series of processes such as cleaning, sorting, packaging, warehousing and logistics, it is difficult for agricultural products to maintain stable quality and consumption experience. Cultivating and developing agricultural brands has enabled many new agricultural operators to embark on the road of standardized production, and through modern industry and digital technology, the whole process of agricultural products from field to table has been standardized. In the process of brand building, agricultural business entities promote the whole agricultural industry to form a more mature division of labor system, optimize the efficiency of industrial factor input allocation, and greatly improve the total factor productivity of agricultural industry. For example, wuchang city, Heilongjiang Province, following the development idea of "building a brand, bringing vitality to an industry and enriching farmers", built a regional public brand of Wuchang rice, comprehensively promoted the standardized production of Wuchang rice, standardized all the processes and procedures such as seed, planting, storage, processing, environment and traceability management, established and improved the whole process standard system from field to table, and promoted the high-quality development of Wuchang rice, with an output value of about 16 billion yuan in 2021. Zhashui County, Shaanxi Province actively builds a regional public brand of auricularia auricula, cultivates a number of auricularia auricula strains unique to Zhashui, promulgates local standards in Shaanxi Province, establishes a technical service system for enterprise demonstration planting and the whole process of auricularia auricula industry, implements the standard awareness rate and reaches 100%, and promotes the transformation of auricularia auricula from relying on traditional experience to modern standardized production, achieving annual cultivation of about 100 million bags of auricularia auricula and production of about 5,000 tons of dried auricula, effectively driving farmers to increase their income.

　　Secondly, agricultural brands communicate both ends of supply and demand, which promotes the adjustment and upgrading of agricultural industrial structure. By creating agricultural brands, the differentiated characteristics of agricultural products such as physical geography, production process, technology and product quality are passed on to consumers, and agricultural brands become a "bridge" for communication between producers and consumers. At the same time, in the process of cultivating and developing agricultural brands, changes in the consumer market are constantly fed back to agricultural business entities, promoting the transformation and upgrading of industrial structure. For example, Qingcaitou was originally a traditional planting variety in Fuling District, Chongqing, and pickled mustard tuber with it was a snack for people on both sides of the Yangtze River. With the fast pace of people’s life, the consumption demand of simple fast food, business trip and accompanying dishes is expanding rapidly. Grasping the opportunity of changing consumer demand, Fuling District has made great efforts to build a regional public brand of Fuling mustard tuber. While adhering to the traditional production techniques, it has continued to develop and promote excellent varieties with high yield and disease resistance and suitable for harvesting machines, keeping up with market development and demand, innovating product research and development, and building a brand matrix. Today, Fuling mustard tuber has become a pillar industry with an annual output value of more than 13 billion yuan. Traditional production techniques have been listed in the national intangible cultural heritage list. The products are sold all over the country and exported to Japan, Australia, the United States and other countries and regions.

　　Thirdly, the creation of agricultural brands has promoted the upgrading of industries with traditional characteristics and advantages, and helped rural revitalization and farmers’ income increase. At present, China’s consumer demand has changed from focusing on quantity growth to pursuing quality life, and the development of agricultural industry has also paid more attention to improving quality and efficiency. Developing agricultural brands can effectively promote the upgrading of industries with traditional characteristics and advantages, and help revitalize rural industries and enrich the people and strengthen agriculture. For example, xuwen county is the largest pineapple producing area in China, accounting for more than one third of the country’s pineapple planting area. With the increasing variety of fruits, xuwen county has built Xuwen pineapple regional public brand, promoted excellent varieties of pineapple, issued regional public brand logos, established pineapple buyers’ alliance, vigorously organized the docking of production and marketing, and promoted Xuwen pineapple sales growth. The industrial output value climbed from 980 million yuan in 2018 to about 2.5 billion yuan in 2022, which led to about 50,000 farmers. There are many industries with traditional advantages like Xuwen pineapple in China, and brand building is a powerful means and an effective path to promote its upgrading, help rural industries revitalize and realize enriching the people and strengthening agriculture.

　　"internet plus" promotes brand building

　　What are the practices of cultivating and developing agricultural brands in China in e-commerce marketing and digital empowerment?

　　Qi Yunlan (Research Fellow, Institute of Market Economy, the State Council Development Research Center): In recent years, all localities have attached great importance to the cultivation and development of agricultural brands, and used various marketing methods such as the Internet, e-commerce and new media to publicize agricultural brands, expand marketing channels of agricultural products, empower agricultural fields with digital technology, and enhance the level of agricultural modernization and promote the construction of agricultural brands through digitalization, networking and intelligence.

　　The first is to introduce an e-commerce platform to help build a high-quality agricultural brand. From a national perspective, many villages and towns based on the advantages of local resources, by introducing e-commerce platforms such as Tmall and JD.COM, cultivate e-commerce talents, open up channels for production and marketing, and improve the scale and standardization level of production and sales of advantageous agriculture, so that one village (or several villages) can own a brand product or brand industry with great market potential, obvious regional characteristics and high added value. Moreover, the scale of some village-level dominant brand agricultural products has gradually expanded to towns and even counties, forming dominant industrial clusters with brand influence, and the brand development effect and spillover effect are remarkable. Taking changge city as an example, e-commerce has become an important starting point to promote the innovation and development of brand agriculture. Twenty well-known e-commerce platforms, such as Alibaba International Station, Tmall, AliExpress and JD.COM, were introduced locally, and more than 20,000 online stores were opened. In 2022, e-commerce transactions reached 16.7 billion yuan.

　　The second is to strengthen the introduction and cultivation of e-commerce talents, widely use new media marketing methods such as live broadcast and short video, publicize and promote agricultural brands, and expand agricultural product marketing channels. From the practice of various places, great efforts have been made to strengthen the training and introduction of e-commerce talents and enrich product connotations and scenarios. Many local governments, together with industry associations, have organized training to explain the contents of "prospering agriculture through several businesses", live broadcasting with goods, brand building, etc., and trained a group of "new farmers" who have mastered the operation ability of new media to strengthen the promotion of agricultural brands. At the same time, build online celebrity products and expand the market influence of agricultural brands. In some places, in the construction of agricultural brands, through the cooperation of the government, enterprises, farmers and associations, the quality of agricultural products is improved and the brand connotation is enriched from the aspects of building a green production system and a quality and safety traceability system. With new e-commerce formats such as content e-commerce, interest e-commerce and social e-commerce as the carrier, we will build brand image through multiple platforms and channels, enrich marketing scenarios and promote the sales of agricultural products. According to data from the Ministry of Commerce, in the first half of 2023, the online retail sales of rural physical goods nationwide was 1.02 trillion yuan, up 11.3% year-on-year.

　　Third, relying on big data of agricultural products trading and using digital technology as a means to optimize the whole agricultural industry chain and accelerate the development of agricultural branding. In recent years, rural e-commerce is extremely active, and a large number of online real-time transaction data are gathered in the process of agricultural products e-commerce transactions. Agricultural product producers and operators in various places use the user data of e-commerce platform to understand consumer demand in multiple dimensions, and apply big data acquisition and analysis technology to dynamically match the supply chain management of agricultural products and fill the shortcomings of sales channels. At the same time, improve the traceability system of agricultural products, standardize and optimize the whole industrial chain and supply chain of agricultural products from production, packaging, transportation, storage to sales and after-sales, and increase the added value and brand premium of agricultural products. For example, in promoting "developing agriculture through several businesses", Shanghai connects the supply and demand sides through platforms such as Life, Pinduoduo, and Meituan to promote the sales of agricultural products, especially brand-name agricultural products, and better meet the living needs of urban residents. According to a survey, 42.6% of Shanghai residents are willing to pay a premium of 10% to 30% to choose branded agricultural products, and the online repurchase rate is 84.1%.

　　Fourth, give full play to the guiding role of the government. Relevant departments, in combination with the characteristics of regional agricultural resources, make clear the overall goal and development direction of regional agricultural products branding, and plan the integrated development of regional public brands and industrial clusters. In practice, all localities attach great importance to the construction of special agricultural products production and processing bases, logistics industrial parks, basic information networks and other facilities, providing a strong guarantee for large-scale production, sales and logistics. In particular, by uniting rural e-commerce enterprises, we will jointly build a warehouse-distribution logistics integration base and share warehouse-distribution manpower, material resources and site resources, thus significantly reducing the distribution cost of express delivery enterprises and the storage cost of rural e-commerce enterprises.

　　To sum up, under the background of "internet plus", China’s agricultural brand cultivation methods have been continuously innovated, and the level of standardization, digitalization and traceability has been significantly improved. E-commerce, live broadcast, short video and other new media marketing channels have been widely used in the field of agricultural product marketing, and an agricultural brand development model based on standardized production and quality certification has been initially formed, with digital empowerment, production and marketing docking and brand building as the means.

　　Focus on local products and create a golden business card for regional development

　　How can all localities give full play to their unique resource advantages, do a good job in "local products" and promote the development of agricultural brands?

　　Hu Xiaoyun (Director, China Agricultural Brand Research Center, China Rural Development Research Institute, Zhejiang University): Our country is rich in special agricultural products, which are unique in regional ecology, variety quality, technological characteristics, cultural connotation and product flavor. As an excellent local product, geographical indication agricultural products have become an important carrier to build agricultural brands.

　　Since the beginning of this century, all localities have given full play to their unique resource advantages, done a good job in "local products" articles, from theoretical research to policy support, and started with the creation of regional public brands of agricultural products, so as to brand distinctive agricultural products, enhance the resource value of local products, and achieve a win-win situation for all parties.

　　First, theoretical research helps the development of agricultural branding. The most distinctive resources in China’s agriculture are geographical indication agricultural products based on the ecological and cultural connotations of specific regions. The number of theoretical research results on the creation and management of special geographical indications and regional public brands is increasing. For example, the number of papers on China Knowledge Network with agricultural brands and regional public brands of agricultural products as keywords is increasing, and the theoretical support system for agricultural brand building is constantly being built. The theoretical research of relevant teams in colleges and universities has promoted the development of agricultural brands in China, especially the branding process of high-quality local products, and also promoted the introduction of relevant support policies.

　　The second is to strengthen the protection and management of agricultural products with geographical indications. Based on an international perspective, relevant departments actively promote the protection of origin, the registration of geographical indications trademarks and the registration of geographical indications of agricultural products, promote the development of agricultural products with geographical indications, and learn from the international experience of agricultural products brand development to promote the system design of agricultural brand development. More and more attention has been paid to the development of agricultural brands in various places, and a series of agricultural brand building with local characteristics has been carried out. In 2019, new special signs for geographical indications were released. The Notice of the General Office of the Ministry of Agriculture and Rural Affairs on Doing a Good Job in the Implementation of the Protection Project of Geographical Indications Agricultural Products in 2022 proposes to tap traditional farming culture and cultivate regional brands with geographical indication agricultural products as the core.

　　Third, steadily promote the branding of agricultural products with geographical indications. All localities have promoted geographical indication agricultural products to create a regional public brand of agricultural products with a single category (industry), and become the leading brand and platform brand of local agriculture, which has enhanced the brand value of local products. For example, Yanchi County in Ningxia strives to build a regional public brand around Tan Sheep, and professional institutions design brand strategies and spread brands for it. Yanchitan sheep (meat) has been selected as a national geographical indication protection product, China Agricultural Brand Catalogue 2019 regional public brand of agricultural products, etc. In 2022, the total industrial chain output value of Tan sheep in Yanchi County reached 6.45 billion yuan, and the income from Tan sheep breeding accounted for more than 50% of the per capita disposable income of local farmers. At present, the regional public brands of agricultural products based on geographical indications have more and more market influence, and have formed a brand cluster effect.

　　The fourth is to explore the creation of regional public brands of multi-category agricultural products. Based on the actual situation of mountainous areas in China, such as many agricultural categories, small scale, scattered planting blocks, unique varieties and techniques, relatively poor regional economy and weak regional influence, all localities explore and promote the construction of agricultural brands, create regional public brands of multi-category agricultural products, and force product standardization through branding to improve product quality. Relying on the unique mountain ecological environment, Lishui City, Zhejiang Province has built a regional public brand "Lishui Shangeng" (registered as a collective trademark) of multi-category agricultural products, gathered regional agricultural resources, let "mountain products" go out of the "mountain gate" and enhance the brand value of ecological fine agricultural products. It has formed many industries such as fungi, tea, fruits, vegetables and medicines, and the annual sales of "Lishui Shangeng" agricultural products exceeded 10 billion yuan. Chongqing’s "Ba Wei Yu Zhen", Gansu’s "Gan Wei", Inner Mongolia’s "Tian Fu Hetao", Shandong’s "Jining Li Yi" and Zhejiang’s "Sanqu Wei" and other multi-category regional public brands of agricultural products also rely on the historical and cultural characteristics of various places to strengthen the cultural, narrative, unique and intangible value premium functions of the brands, highlighting the cultural value of local high-quality local specialties.

　　At present, relying on rural regional ecology and high-quality local products to build agricultural brands, local characteristics and cultural values are highlighted, making local local products a golden business card for regional development and effectively promoting local economic development.

    Renovation of new houses, renovation of old houses, and 1000 homes will have 1000 kinds of network needs. From multi-screen to 4K, 8K video entertainment experience, to telecommuting, online learning interaction, to whole house intelligence, etc., the intelligentization of family life has also ushered in an "acceleration period".

    As the most "trendy" optical fiber broadband access mode, China Telecom Jiangsu Company’s all-optical broadband has broken the bottleneck of "broadband has an upper limit" in traditional home networking, completely broke through the network bottleneck of the last ten meters indoors, and truly achieved "fiber to the room", making the network unimpeded and enjoying "freedom of network speed"!

Mass production of the new "Poplar-M" intercontinental missile, restarting the aircraft carrier, resuming the global strategic patrol interrupted by strategic bombers for 15 years, proposing to deploy nuclear weapons in Belarus, and testing the most powerful conventional bomb … In recent months, the Russian army has frequently "shown its sword" and showed its "military muscle" to the world, making the west, which is bent on compressing Russia’s strategic space, nervous.
Lack of funds once trapped hands and feet.
In the 1980s, former Soviet strategic bombers frequently carried out long-range patrol flights. At that time, Tu -95, Tu -22 and Tu -16 strategic bombers were mainly used to carry out global strategic patrol missions, and their patrol areas covered vast areas such as the Pacific Ocean, the Arctic Ocean, the Atlantic Ocean, the Indian Ocean and the Mediterranean Sea. After the disintegration of the Soviet Union, due to the economic depression and the reduction of military expenditure, the Russian army stopped its global strategic patrol activities in 1992.
Since the disintegration of the Soviet Union, the allocation for Russian military spending has been reduced year after year, and by 1999, the actual military expenditure was only $4.7 billion. Russian military personnel refer to this budget as the "death budget".
The funding problem has become the biggest bottleneck restricting Russian military reform and development. Due to the shortage of military expenditure, the Russian military’s equipment cost has been reduced again and again, and it can only repair the existing equipment and purchase a small amount of weapons, and the equipment situation has gone from bad to worse.
According to the statistics of the Russian Ministry of Defense at the end of 1999, the intact rate of aircraft and ships is only 50%, and the intact rate of helicopters and tanks is only 30%. Sergeyev, then Minister of National Defense, said frankly: "At least 30% of Russian weapons cannot be used on the battlefield."
Insufficient military spending has seriously affected the Russian military’s combat readiness and training activities. Due to the lack of fuel, planes lie prone at the airport, tanks are locked in the warehouse, and the training time of air force pilots is much lower than it should be, resulting in frequent flight accidents due to improper operation.
　　Russian troops rallied.
"Russian pilots have been on the ground for too long. It’s time for them to soar." President Putin said.
After Putin took office, he repeatedly said that he would increase military spending, so that the scale of the military budget should not be less than 3.5% of the gross national product. The improvement of Russian economy and the substantial increase of energy income have provided conditions for President Putin to fulfill his promise. In recent years, the Russian military budget has started to grow by leaps and bounds: from 411.5 billion rubles (US$ 1 is about 25.5 rubles) in 2004 to 820 billion rubles in 2007, the Russian military expenditure has increased by more than 20% every year.
The increasing military spending has made the Russian army frown slightly. With money, new weapons can be equipped. In 2006, Russia’s anti-ordering funds reached 236.7 billion rubles, an increase of 53.5 billion rubles compared with 2005. The Russian army greatly increased the procurement of advanced weapons and equipment such as high-precision weapons, efficient reconnaissance and radio electronic warfare complexes, and automated command systems. The "Baiyang -M" intercontinental ballistic missiles were deployed one after another, the first boat of the "God of the North Wind" class strategic nuclear submarine was launched, the new strategic missile "which can break through any anti-missile system" was successfully tested, and the S-400 air defense missile equipment unit, the strategic nuclear force of the Russian army and the combat readiness level of the air and space defense system were greatly improved.
The treatment of Russian soldiers is also improving. Since January 1, 2006, the salaries of Russian soldiers have increased by 15%. President Putin has also formulated the "15+15" plan for this purpose, stipulating that an additional 3 billion rubles will be allocated within two years to guarantee military housing.
With money, the equipment is no longer idle. The Russian army has increased the scale and quantity of military training, carried out long-range raids by strategic bombers, patrolled the ocean by naval formations, conducted missile tests by strategic missile units, and held joint military exercises with the armies of other countries from time to time.
Various reconnaissance activities of the Russian army resumed one after another. Zhikharev, deputy commander of Russian long-range aviation, said not long ago that Russian long-range aviation plans to conduct strategic patrol flights twice a week, covering the northeast Atlantic, Norwegian waters, the North Sea, the Sea of Japan and the area near the Arctic Circle. In fact, Russian bombers had carried out various reconnaissance flights many times before President Putin announced the resumption of strategic bomber patrols. According to reports, on August 8, two Tu -95MC bombers of the Russian Air Force went to Guam for strategic patrol and conducted reconnaissance and surveillance on US military bases and exercises.
Show "chest muscles" and "fists" to the west
Not long ago, a photo released by the media was quite eye-catching. In the photo, President Putin is fishing by the Yenisei River. The president didn’t wear a shirt, and the August sun shone on his strong chest muscles. An article on the website of The Times of England said, "Putin is showing his strength with bare arms." Indeed, President Putin showed not only hexapod muscles, but also clenched fists.
Take the global patrol of strategic bombers as an example. The Tu -160 and Tu -95 strategic bombers that perform tasks are all equipment of the last century. Although they are a little old, they are still quite easy to use. Tu -160 is an important means to destroy enemy deep targets. It can launch short-range attack missiles at subsonic low altitude, and can also carry out missile strikes and nuclear strikes at high altitude and supersonic speed. Tu -95 is equipped with advanced airborne electronic equipment, navigation system and new cruise missiles. At the same time, it is equipped with multifunctional navigation attack radar, optical aiming system, electronic jamming equipment and aerial refueling equipment, which has long-range strategic attack capability.
The west was also quite nervous about whether these bombers were cruising with live ammunition, and it was not until Russian military personnel officially said that the plane would fly with practice bombs that they breathed a sigh of relief.
On September 11th, the news that the Russian military successfully tested and exploded the most powerful conventional bomb in the world surprised the West again. It is reported that this super bomb, known as the "father of the bomb", contains 7.8 tons of new high explosive. Although the total amount of explosive is slightly less than that of the "mother of the bomb" of the US military, it is four times more powerful than its opponent because of the advanced formula, and the explosion radius reaches an astonishing 330 meters. From the TV screen, a huge crater appeared on the ground after the explosion of the "Father of Bombs", and the building near the test site was completely destroyed.
The Russian army frequently shows its "chest muscles" and "fists", which means more tit-for-tat with the West in addition to the recovery of military strength brought about by the enhanced economic strength. Taking Russia’s resumption of the global patrol of strategic bombers as an example, Colonel Alexander Drobyshevski, spokesman of the Russian Air Force, once said that Russia unilaterally stopped the long-range strategic patrol mission of strategic bombers to remote areas in 1992. However, other countries continue to carry out similar flights, which poses a certain threat to Russian national security.
For Russia, there are still many places where security is threatened. For example, despite Russia’s strong opposition and Russia’s initiative to propose alternatives, the United States insists on deploying anti-missile defense systems in the Czech Republic and Poland. Although the United States has repeatedly claimed that the deployment of anti-missile systems in Eastern Europe is aimed at countries such as Iran, its real intention should be known to everyone on earth. Since the United States can run to the door to deploy anti-missile systems, Russian strategic bombers can certainly fly out of the country to launch.
Although the west has a low-key response to the frequent "swords" of the Russian army, it has always been on high alert in secret. On September 6th, when the Russian-Tu -95 strategic bomber flew to the Atlantic Ocean to carry out strategic patrol mission, Britain dispatched four Tornado F-3 fighters and Norway dispatched two F-16 fighters to intercept it. In the future, Russian strategic bombers will cruise regularly, and it is not known whether there will be a misfire between the two sides.
When analyzing the reasons for the recent series of big moves by the Russian army, the British "Economist" magazine believes that the external reasons are secondary, and the main reason is that Putin and the Kremlin want to restore their inherent culture and rebuild Russia’s glory.
National strength is the foundation of military strength, and military strength is the display of national strength. From this perspective, the British "Economist" view is not unreasonable. (Author: Xiao Lan Editor: Zhao Ligen/Internship Editor: Gao Lili)

　　　　CCTV News (Reporter Chu Dekun reports from Shenyang): In the development history of China machinery industry, there are two enterprise names such as Lei Guaner: Shenyang Heavy Industry Group Corporation and Shenyang Mining Group Corporation. As the "mother machine" of China’s heavy machinery industry, it was once a symbolic enterprise of China’s machinery industry towards industrialization and a business card of Shenyang. In history, Shenyang, an old industrial base, has been famous for its many glories created by Shenzhong and Shenkuang.　

　　　　On the morning of December 16th, looking back on the five-year revitalization? The interview group of the network media in the northeast came to Tiexi District, Shenyang, and visited and interviewed northern heavy industries Group Co., Ltd., which was revitalized after the reorganization of Shenzhong and Shenkuang.

　　　　If it is said that entering the top 500 machinery companies in China and the top 500 machinery companies in the world is the embodiment of the comprehensive strength of enterprises, then having the manufacturing capacity of shield machines shows that northern heavy industries Group Company has already possessed the core elements of a world-class enterprise, and changed its past products. Big black and rough "image, realize gorgeous turn to become a" high-precision "product manufacturer of major equipment.

　　　　Shield machine is known as the most advanced large underground boring machine in the world, and it is a representative of national industrial level. When it comes to northern heavy industries, we can’t help but pay great attention to its core product shield machine. The independent research and development of shield machine is the highlight of major innovation of northern heavy industries Group. With the goal of building the world’s largest shield machine manufacturing base, northern heavy industries Group Company has made a series of optimization and integration on the existing resources of shield machines, forming a strong technological innovation capability.

　　　　The workers in the factory told the reporter such an example. On December 8th, the old factory of northern heavy industries Group reloaded the workshop, and the workers were actively assembling two hard rock roadheader machines with a diameter of 5.94m and two EPB shield machines with a diameter of 6.28m for Wuhan Metro. Adapting to the old factory is the reloading workshop of the new factory in northern heavy industries, which is located in Shenxi Industrial Corridor. Workers are debugging three shield machines for Shenzhen Metro and Shenyang Metro, ready for acceptance. It is very rare for an enterprise to assemble seven shield machines at the same time in China and even in the world.

　　　　At present, the financial crisis that originated in the United States will inevitably have a certain impact on northern heavy industries Group, which provides equipment for major projects such as mining, metallurgy, electric power and mining. According to preliminary statistics, the suspension of construction contracts has reached 1.9 billion. However, the decision-makers in northern heavy industries clearly realized and seized the business opportunities contained in the crisis. They took precautions and put forward that they should make full use of their own advantages in the crisis, create new business opportunities, open up new markets and turn the crisis into an opportunity for development.

　　　　At present, northern heavy industries Group not only designs and produces all three types of shield machines in the world, but also produces the largest diameter shield machine in the world. At present, the company has received a total of 37 orders for shield machines, with a total contract amount exceeding 3 billion yuan. Shield machine not only greatly enhances the corporate image of northern heavy industries, but also becomes the most important tool for enterprises to cope with the world financial crisis.
