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.

　　On the 19th, a performance conference was held in Hong Kong. In 2023, the company realized an operating income of 372.6 billion yuan (RMB, the same below), up 5% year-on-year, and the profit attributable to shareholders of the company reached 18.7 billion yuan, up 11.8% year-on-year.

　　Chen Zhongyue, Chairman of the Board of Directors, said that the company firmly fulfilled its two main responsibilities of being a network powerhouse and a digital China, focusing on two main businesses: networking communication and computing the network and being intelligent. With the increasingly perfect coverage of 5G network, the company’s investment focus has shifted from the stable networking communication business to the high-growth network computing and intelligence business. In 2023, the capital expenditure decreased year-on-year, and the network investment has already turned to an inflection point.

　　Give consideration to scale increaseValue enhancement, many businesses have developed well.

　　Chen Zhongyue said that in 2023, the strategic system will continue to deepen, and the current operation and long-term development will be actively coordinated, focusing on the two main businesses of networked communication and network computing and intelligence, so as to achieve effective improvement in quality and reasonable growth in quantity.

　　Performance data shows that,In addition to both business and profit growth, the return on net assets reached 5.4%, achieving the best level in recent years; The annual dividend was 0.3366 yuan per share, up 22.8% year-on-year, significantly higher than the basic earnings per share of 11.8%.

　　The revenue of networked communication business reached 244.6 billion yuan, including mobile networking, broadband networking, TV networking, private line networking, communication business and information business, and the revenue scale reached three quarters of the total revenue of the main business. The scale of networked communication users exceeded 1 billion, and the scale of mobile users reached 333 million, including a net increase of 10.6 million in 2023, and the penetration rate of 5G package users reached 78%, up 12% year-on-year.

　　The revenue from the network intelligence business is RMB 75.2 billion, including Unicom Cloud,, the integration of several disciplines, data services, digital intelligence applications and network security, the revenue scale accounts for about a quarter of the total revenue of the main business, and brings more than half of the new service revenue to the company. Unicom Cloud realized revenue of RMB 51 billion, up 41.6% year-on-year.

　　In accelerating the construction of digital information infrastructure, the coverage level of mobile networks has been continuously improved, with more than 1.21 million 5G IF base stations and 680,000 900M base stations. In response to the "double carbon" policy, in 2023, it will save about 39 billion yuan in operating expenses, reduce carbon emissions by about 11.5 million tons, and save about 340 billion yuan in capital expenditure.

　　Focusing on the main business, innovating and developing the industry is still in a good development period.

　　At the press conference, China Unicom made it clear for the first time that networking communication and computing network intelligence are the two main businesses of the company.

　　Chen Zhongyue said that taking these two items as the main business has fully considered the development reality of the company and the development trend of the industry. They are complementary and mutually conditional. Digital business is an important engine for the development of networked business, and networked business is an important foundation for the development of digital business. Both are basic businesses, and both need innovation and development.

　　Facing the wave of digitalization, intelligence and greening, China Unicom expressed its active embrace.To speed up the construction of new quality productive forces, we should start from three aspects: First, we should lay out strategic priorities, formulate an overall development plan, and systematically lay out intelligent computing services, research and development of large models, high-quality data sets, security and applications. The company has also set up an innovation center to gather high-level talents and strive to build artificial intelligence into an important engine for the company’s high-quality development.

　　The second is the key capacity building, which is mainly reflected in computing services and large models. In terms of providing specialized computing infrastructure services, a "1+N+X" computing capacity system has been laid out, including a single ultra-large-scale computing center, n computing hubs for training and reasoning, and x data-based computing and reasoning nodes.

　　The third is the key exploration of application, focusing on the big model of the industry. At present, phased results have been achieved in the internal scenes of online customer service, as well as industry-oriented government affairs, industry, clothing and other fields.

　　Speaking of capital expenditure, Chen Zhongyue said that in the first five years since entering the 5G construction cycle, the annual capital expenditure has continued to grow, but it has declined in 2023, reflecting that the network investment has turned to an inflection point. It is estimated that the capital expenditure in 2024 will be reduced by 12% on the basis of 73.9 billion yuan last year.

　　For the future development, Chen Zhongyue believes that the communication industry is still in a good development period, and China Unicom will help enterprises to step up through a series of strategies to strengthen enterprises, including strengthening enterprises through science and technology, talents, reform, intelligence and brand.

Wang Chuanfu, chairman and president of BYD, announced at BYD’s intelligent strategy conference on the evening of February 10 that the high-level intelligent driving system "Eye of God" was officially released and divided into three versions. Among them, the three-laser version (DiPilot 600) is mainly used for looking up models, the laser version (DiPilot 300) is mainly used for Tengshi and BYD models, and the three-eye version (DiPilot 100) is mainly used for BYD models.

    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"!

    The optical fiber is fully connected and wired in advance, which is both practical and beautiful.

    A good choice of broadband can not only improve work efficiency, but also enjoy watching dramas, playing games and enjoying the intelligence of the whole house. Jiangsu Telecom FTTR all-optical broadband supports 2000M, which can break through to carry 10 gigabit with the increase of network speed.

    At present, optical fiber layout can be divided into two ways: one is that the optical fiber can be laid into the room in advance when it is not decorated; One is to reuse the invisible optical fiber after renovation, or to pull out the network cable and re-deploy the optical fiber to the room.

    For the new house decoration, Jiangsu Telecom’s all-optical broadband can be used as a part of the decoration hardware, and the optical fiber is laid in advance, which is "perfect stealth" to adapt to various decoration styles.

    "At first, I was worried that’ fiber-to-the-room’ would make the room full of messy internet cables, and the new house was going to be luxurious. I couldn’t accept such a messy aesthetics." When Ms. Liu just renovated her house, she contacted Jiangsu Telecom staff to install all-optical broadband. "I didn’t expect that Jiangsu Telecom’s FTTR all-optical broadband was so intimate, taking into account practicality and aesthetics, and it could look neat and beautiful after installation!"

    Jiangsu Telecom’s all-optical broadband is based on all-fiber distributed architecture, which makes Wi-Fi distributed within a reasonable range, avoids wall attenuation, and makes every room full of Gigabit signals.

    Gigabit full coverage, seamless switching of old house renovation network

    The balcony and bathroom signals are sometimes absent; To make a video call, you have to find a place with a good signal; Children listen to an online class at home, but because the network in the study is slow, the class experience is greatly reduced; WiFi in and out of the room is disconnected, and the delay of automatic network connection is accelerated manually … With the increasing demand of home network, the "old house" will also usher in a "new transformation"!

    In the renovation of the old house, Jiangsu Telecom’s all-optical broadband can realize the whole house optical fiber wiring, and the ultra-Gigabit Wi-Fi can cover every room. It adopts the 1-N mode and plays a set of "bandwidth+network cable+router+networking" combination boxing, and uses all-optical networking intelligent terminals+invisible network cables to lay out the whole house, so that the signals everywhere are full.

    "In addition to the better network speed, the biggest improvement is that the home appliances I bought before can finally be stably controlled! Previously, due to the poor network, smart speakers often did not respond to voice control. Now, air conditioners and heating can be awakened by voice across the room, and the life happiness index will be improved! " Mr. Li’s family, who lives in Jiangsu, is full of praise for the newly installed all-optical bandwidth.

    It is reported that each sub-route of Jiangsu Telecom FTTR all-optical broadband can provide gigabit rate connection, and at the same time, it has three highlights: high bandwidth, high penetration and high speed, and supports up to 256 devices to be networked at the same time, so that the whole family can enjoy the new intelligent experience of the whole house!

    Gigabit full coverage has been achieved, and the broadband maintenance of Jiangsu Telecom is also "intimate, warm and assured"! All-optical broadband intelligently manages the whole family FTTR all-optical network through the intelligent operation and maintenance platform. Even if there is a network problem, it can remotely locate the problem and repair it with one button, which is absolutely an indispensable "maintenance coup" for office workers!

　　The world economy is accelerating the transformation to economic activities with the network information technology industry as the important content, and China is in the historical process of rapid development of informatization.

　　On April 20-21, the National Network Security and Informatization Work Conference was held in Beijing. General Secretary of the Supreme Leader attended the meeting and delivered an important speech. He emphasized that informatization has brought a golden opportunity to the Chinese nation. We must keenly seize the historical opportunity of information development, strengthen positive publicity on the Internet, safeguard network security, promote breakthroughs in core technologies in the information field, give full play to the leading role of information technology in economic and social development, strengthen the integration of defense and civilian technologies in the network information field, actively participate in the process of international governance of cyberspace, promote the construction of a network power through independent innovation, and make new contributions to winning the Chinese dream of building a well-off society in an all-round way, winning the great victory of Socialism with Chinese characteristics in the new era and realizing the great rejuvenation of the Chinese nation.

　　Standing at the height of the historical development of mankind and the overall situation of the Party and the country, the important speech of the Supreme Leader scientifically analyzed the trend of informatization reform and our historical mission, systematically expounded the strategic thinking of strengthening the country by network, and profoundly answered a series of major theoretical and practical questions related to the development of the network information industry. It is a programmatic document guiding the development of network security and informatization in the new era, and has great and far-reaching significance.

　　Since the 18th National Congress of the Communist Party of China, the CPC Central Committee has made a series of major decisions and put forward a series of major measures to promote the historic achievements in the cause of online information. From the speech of the Supreme Leader General Secretary at the Second world internet conference to the important speech of "April 19th", from the Outline of National Informatization Development Strategy, National Cyberspace Security Strategy to the Cyber Security Law, and until the convening of the National Cyber Security and Informatization Work Conference, we have continuously promoted theoretical innovation and practical innovation, not only stepping out of a way to govern the Internet with China characteristics, but also putting forward a series of new ideas, new viewpoints and new judgments, thus forming the strategic thinking of a cyber power.

　　To understand and adhere to the strategic thinking of strengthening the country by network, we should deeply understand that informatization is a golden historical opportunity for the Chinese nation. Throughout the history of world civilization, mankind has experienced agricultural revolution, industrial revolution and information revolution. The information revolution that is being carried out in full swing all over the world is at a time when the Chinese nation is approaching the center of the world stage as never before, approaching the goal of realizing the great rejuvenation of the Chinese nation as never before, and having the ability and confidence to achieve this goal as never before. Whoever seizes the opportunity in the information revolution will firmly grasp the initiative of the times. We must not hesitate or slack off on this historical opportunity, and we must firmly grasp it in our hands.

　　To understand and adhere to the strategic thinking of strengthening the country by network, we should systematically, comprehensively and independently innovate to promote the construction of a strong country by network. General Secretary of the Supreme Leader has put forward a series of measures and key points on how to build a network power, including improving the comprehensive network governance capacity and forming a comprehensive network governance pattern with multi-agent participation and various means; Establish a correct concept of network security and actively develop the network security industry; Accelerate the breakthrough of core technologies in the information field; Take the lead in practicing the new development concept and promote and upgrade the development of new industrialization, urbanization and agricultural modernization as a whole; Promote the formation of a pattern of all-factor, multi-field and high-efficiency deep integration of military and civilian development; Promote the reform of the global Internet governance system; Strengthen the centralized and unified leadership of the Party Central Committee on the work of online information, and ensure that the cause of online information always advances in the right direction. These measures have formed a complete and comprehensive system, highlighted the ability of independent innovation, and provided specific action guidelines for the construction of a network power.

　　"At any time, you can make contributions because of your capital, and profit from it with the ability of all things." The network letter business represents a new productive force and a new development direction, which is closely related to the people’s sense of acquisition, happiness and security. We must conscientiously study and understand, unify our thoughts and actions with the strategic deployment of the Party Central Committee on network information work, grasp all the work in place with the spirit of nailing nails, adhere to the strategic thinking of strengthening the country by network under the strong leadership of the Party Central Committee, strive to promote the construction of a network power, firmly grasp the initiative of the times, and win a glorious future for the Chinese nation.

　　The Prime Minister-the President-the Prime Minister, who accomplished this cycle smartly, seems to have returned to the original starting point. But this time, he is closer to the Russian dream.

"Tough guy" Putin rarely "smiles childishly", although sunglasses block his most vivid expression. Agence France-Presse

　　His annual salary is only $74,000, which is rather shabby compared with Singapore Prime Minister Lee Hsien Loong’s high income of more than $2 million, but he thinks he is not only the richest man in Europe, but also in the world. At the press conference in early 2008, he made a deep confession: "My wealth is that the Russian people asked me to lead this country twice."

　　The way of judo, the way of governing the country

　　He is only 170 cm tall, but he is the most attractive man in Russia. The song "Marry someone like Putin" has been sung all over the streets. In the middle of the year, a tabloid revealed that he had secretly divorced and was about to marry Kabayeva, a gymnastics beauty, which made him furious. On July 28th, he and his caring wife lyudmila ushered in the silver wedding anniversary, and all the rumors were broken.

　　He is one of the busiest politicians in the world and laughs at himself as a "never-ending rowing slave on a sailboat", but he is obsessed with sports and has a special liking for judo. October 7th this year is his 56th birthday. As the honorary president of the International Judo Federation, he attended the release ceremony of the teaching film "Learn Judo from Putin". In the film, he personally demonstrated judo skills, introduced the history of judo, and explained the essence of judo: "This is a noble, tolerant and mutual aid sport, because the basic principles of judo are completely in line with an inclusive society."

　　When the financial tsunami struck, Russia, whose economic engine was oil and gas export, suffered a heavy blow. However, authoritative polls in November showed that 80% of Russians still firmly believed in the development direction of their country, and that Putin was the most wise leader of the country in the past 100 years, whether he was president or prime minister.

　　Low-key handover is as tacit as ever.

　　In May this year, Putin quietly moved out of the Kremlin, "only taking a pen".

　　However, there are only 27 hours for an official to be light-skinned. The Duma passed the nomination of his prime minister by a high vote, and he stepped into the prime minister’s office in the White House on the Moscow River non-stop.

　　The word "Mapp combination" instantly swept Russia.

　　At that time, Yeltsin, who was old, handed over stormy Russia to Putin. Many people said that Putin was definitely just a puppet, but it turned out that they were wrong.

　　Eight years later, Medvedev dragged Putin’s long shadow to the top of state power, and people inevitably wondered: Is Putin willing to obey this schoolmate who is 14 years younger than him? Will Medvedev abandon Putin when he is in power?

　　Now, all doubts have vanished.

　　Putin is the prime minister and the first hero of Medvedev’s election as president. The United Russia Party, which he chairs, occupies 315 of the 450 seats in the Duma. If he is a power lover, he can use the party to control the parliament, amend the constitution and even impeach the president, but he has not done so. His statement hit the floor: "I will not be president before 2012."

　　Every time he appears in public with Medvedev, Putin is very low-key, never steals the limelight, and respects Medvedev’s presidential authority everywhere.

　　Chechen President Kadyrov renamed Victory Street in Grozny Putin Street to celebrate his birthday. He immediately asked the spokesman to respond, saying that although he had no right to influence local decision-making, he did not want similar situations to happen again.

　　And Medvedev, who was chosen by his eye, did not live up to expectations. The cooperation between him and Putin in internal affairs and diplomacy is quite tacit. The Mapp combination has withstood the tests of NATO’s eastward expansion, the deployment of missile defense system by the United States in Europe, and the war in the South Caucasus, and the government has operated diligently and maturely.

　　Medvedev often emphasizes that he and Putin have cooperated well and each has his own duties. Instead of forming a dual regime, he will show high efficiency.

　　The prestige of the general’s transposition is undiminished

　　As prime minister, Putin focuses on the management of the national economy and people’s livelihood. The growth rate of Russian economy this year is expected to be 6.8% ~ 6.9%, which is a rare answer. In the current financial crisis, he resolutely announced that no matter what the situation is, the Russian government will not change its investment plans involving housing, medical care and education, nor will it cut wages and pensions.

　　The generals have been transferred, but Putin’s prestige has not diminished at all, and so has it internationally. At the last meeting in Sochi this year, Bush praised Putin as a "strong leader" and "never afraid to say what he wants to say".

　　Swinging Buick Palace and returning to the White House, the prime minister’s career is not completely unfamiliar to Putin. More than eight years ago, it was from here that he entered the Keke Palace and was transformed from the Prime Minister into the President. However, returning to the old place after eight years is not what it used to be. Eight years ago, Russians thought he was a mystery by being unsmiling and nameless. Now, he has been molded into a god to a great extent. It is believed that he will make a comeback in 2012 and return to Keke Palace. Because everyone still remembers his rhetoric in those days: "Give me 20 years and give you a brand-new Russia."

　　Vanity Fair, a famous American fashion magazine, pushed Putin to the first place among the 100 most influential people in the world in 2008. The reason is simple. He revived the Russian economy, paid off huge foreign debts, rebuilt the army, restored the pride of the Chinese people, and regained Russia’s international influence … (Reporter from the International Herald Tribune, Tong Shifen, from Beijing)

Explain the valve knee.

The one I received was not practical, but a model, but this one is really not a model.

First of all, let’s have a look. For example, the mouth here is one, which means two, and this is two. This is one with six, and this is two. This side should be six sevens, and the back side should be eight at the top. This side must follow the drawing, and I don’t remember it clearly. It has to be played against it.

The torque on this side is 10 Nm in all aspects. The warning is 5 Nm first, and the tightening is 10 Nm after warning is 5 Nm. The two screws on this side correspond to the screws on the exhaust socket pipe, and this side should also be 10 and 12. These two should be two when they were wrong just now. The ignition coil is inside, and the cannon plug is inside. The electromagnetic side is brand new.

Isn’t there a bypass room here after loading, so there is a gift here, so you must push it up after loading with this small bag, otherwise it will be pressure-relieved, and it will be exactly the same as whether it is loaded or not, and the waste gas will still be oily here, so this thing should be inserted in time after loading.

Here is the antifreezing valve, and here is the antifreezing valve of the exhaust pipe. It costs 39 yuan to buy the pipe, the oil inlet and the cover separately. This is a complete set.

In the past five years, the overall situation of the world has changed, the epidemic situation in the century has been violently impacted, and the risk challenges have followed, and the stormy waves are gripping. Under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, historic achievements and changes have taken place in various undertakings of the party and the country. Premier Li Keqiang’s report on government work is a practical chapter on government work that thoroughly implements Socialism with Chinese characteristics Thought of the Supreme Leader in the new era and the spirit of the 20th Party Congress, a summary of the laws and experiences of high-quality development in the past five years, and a policy-oriented declaration on restoring economic growth in the post-epidemic era, which fully embodies the firm stand with a clear-cut stand, profound thinking from practice, and the scientific spirit of seeking truth and being pragmatic. I fully agree with the government work report. The plan and budget reports are also very realistic, and I fully agree with them. Two suggestions are put forward: First, regarding the issue of supporting small and medium-sized enterprises, the financing environment of small and medium-sized enterprises should be further optimized, and the capital occupation of small and medium-sized enterprises by upstream and downstream should be further rectified. Second, on the issue of solidly promoting the strategy of coordinated regional development, we should support greater agglomeration and better development of industries in high latitudes.

It is a good report that holds high the banner, is pragmatic and inspiring. In the past year and five years, China’s economic and social development has made remarkable and extremely difficult achievements, which are fundamentally due to the steering of the Supreme Leader General Secretary and the scientific guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era. We should focus on the primary task of high-quality development, give play to the powerful magic weapon of the United front, make extensive efforts to promote Chinese modernization, support "two establishment" and achieve "two maintenance" with practical actions.
