CCTV News:After the United States and China signed on September 28th and October 17th, respectively, the Airworthiness Implementation Procedures of the Civil Aviation Administration of China and the Federal Aviation Administration of the United States came into effect on October 17th. This agreement can simplify the accreditation process for C919, ARJ21 and future domestic aircraft to enter the United States.

　　At present, the first domestic large passenger plane C919 has been transferred from Pudong base to Yanliang, Xi ‘an. This indicates that the inspection flight test of C919 in Shanghai has come to an end, and the next step of research and development flight test and airworthiness evidence collection has begun.

　　As early as 2010, Zhenjiang New District seized the historical opportunity of the launch of the large aircraft project and began to build an aerospace industrial park in Zhenjiang New District. Up to now, Zhenjiang New Area Aerospace Industrial Park has a planned area of 10 square kilometers, including 6 square kilometers in the south area, with 150,000 square meters of professional carriers, mainly developing aerospace new materials and parts industries; The north area is 4 square kilometers, supported by Dalu General Airport, which mainly develops the assembly of large aircraft parts, general aircraft manufacturing assembly and general aviation related services. The overall orientation of the park is to build a design, research and development, production base and navigation comprehensive service base for general aircraft, new aerospace materials, aircraft interiors and parts with leading development advantages.

　　Zhenjiang Road General Airport

　　Industrial agglomeration is formed due to large aircraft projects.

　　In 2009, at that time, the country proposed to gather global wisdom and national strength to develop domestic large aircraft. After winning the bid, China Aerospace Science and Industry Group, with military background, built the Aerospace Seahawk, mainly for supporting large aircraft. At the same time, we also hope to promote integration of defense and civilian technologies and promote the industrialization of new materials.

　　After several years’ unremitting efforts, Aerospace Haiying has been successfully promoted from B-corner, a supplier of C919 for Comac, to an exclusive supplier, and has undertaken four work packages, including rear fuselage section, aileron, front fuselage section and vertical tail composite material, of China Comac C919 large passenger aircraft, accounting for more than 40% of all composite parts.

　　It is no accident that the space eagle settled in Zhenjiang, which originated from Zhenjiang’s strong support and encouragement to the aerospace industry. Aerospace industry is one of the six strategic emerging industries in Zhenjiang. On April 25th, 2013, the National Development and Reform Commission issued the Notice on Printing and Distributing the Planning of the Modernization Demonstration Zone in Southern Jiangsu, which only put forward the requirement for Zhenjiang to build a joint innovation platform for aviation industry in Industry-University-Research relying on Zhenjiang General Aviation Base. In recent years, the aerospace industry has developed rapidly from scratch in Zhenjiang New District, and has become an advantageous and characteristic industry with high visibility and influence in the whole province and even the whole country.

　　More than 30 enterprises in Zhenjiang participated in the research and development of major national projects such as the first domestic large aircraft C919, Yun 20, Jiaolong 600, ARJ21 and AC313, among which 11 enterprises were among the cooperative supporting suppliers of Comac C919, including Zhenjiang New Area Fischer Aviation Parts (Zhenjiang) Co., Ltd., Aerospace Haiying Special Materials Co., Ltd., Jiangsu Meilong Aviation Parts Co., Ltd., Jiangsu Golden Flight Aviation Technology Co., Ltd. and other aviation-related enterprises.

　　At present, C919 has 730 orders from 27 customers. The ARJ21 new regional aircraft has 433 orders from 20 customers. In the future, the C919 aircraft project will bring rare development opportunities to these enterprises, and at the same time, it will attract more and more aerospace enterprises to settle here. Zhenjiang City has made all positive preparations for this.

　　Industrial extension due to large aircraft project

　　In addition to supporting enterprises for large aircraft projects, a number of general aviation manufacturing projects have also gathered in the Aerospace Industrial Park of Zhenjiang New District.

　　Relying on the aerospace industry foundation, Zhenjiang New Area Aerospace Industrial Park has introduced six general-purpose machine projects, including three fixed-wing aircraft manufacturing projects of German EA500, American Greisel and American Big Brown Bear, and three rotorcraft manufacturing projects of American Schiller helicopter, Anxiang Taiyue aerial drone and Feirui F200 unmanned plant protection machine. In addition, many general aviation manufacturing projects are being considered to settle in Zhenjiang New Area Aerospace Industrial Park.

　　At present, the domestic navigation manufacturing industry develops rapidly in the fields of helicopters and small and medium-sized fixed-wing aircraft with relatively low technical threshold, which are involved in the layout of navigation manufacturing industry in aviation industrial parks everywhere, and the production scale and technical level are constantly improving.

　　In the future, in addition to the supporting enterprises of large aircraft projects, Zhenjiang New Area Aerospace Industrial Park will gather more general aviation manufacturing and supporting enterprises, give play to the industrial agglomeration benefits, and promote the R&D and manufacturing development of the general aviation industry. In 2017, the Civil Aviation Administration of China issued the 13th Five-Year Plan for General Aviation Development, which also clarified "cultivating the regional service function of Dalu General Airport in Zhenjiang New District, supporting the construction of a floating airport by making use of the advantages of rivers, lakes and seas, and exploring the new mode of sharing transportation and general airport management" at Dalu General Airport in Zhenjiang New District. This provides Zhenjiang New Area with stronger infrastructure guarantee and huge development space for developing general aviation amphibious aircraft R&D and manufacturing.

　　According to the "Thirteenth Five-Year Plan" of the aerospace industry officially released by Zhenjiang New District, it is planned to build "an aviation town"-Dalu Navigation Town. The town will take the aviation industry as the core and rely on the existing industry, airport, airspace and tourism resources to build two bases of "aviation manufacturing" and "navigation operation", and integrate the two industries of "Dongxiang Humanities" and "air sports" to build the aviation industry. In order to better promote the construction and development of "aviation town" and let more people participate in and share the achievements of the development of aerospace industry, the 2017 Zhenjiang New Area Aviation Carnival, with the theme of "flying over dreams and being suitable for Zhenjiang", was held in Zhenjiang New Area from November 17 to 19, 2017, with the support of Zhenjiang New Area Aerospace Industrial Park Management Office, Jiangsu Dalu Aviation Industry Development Co., Ltd. and China Aircraft Owners and Pilots Association.

　　There is no doubt that China is a manufacturing power in the world. However, today, the manufacturing pattern of countries in the world is changing. Germany proposes Industry 4.0, the United States proposes re-industrialization, and China also proposes "Made in China 2025", vowing to make China a manufacturing power. At present, although in aviation manufacturing, many high-precision, sophisticated equipment are imported from abroad, and there is still a big gap between domestic equipment and them, it is not that China cannot reach this level. This is a question of quality assurance system. As long as all links are properly controlled and strictly implemented according to standards, China’s equipment can also reach high-precision, sophisticated.

　　At present, Zhenjiang Aerospace Industrial Park is gathering and introducing a number of technologies, new materials, new equipment and computer technologies related to aerospace manufacturing, and building it into a design, research and development, production base and navigation comprehensive service base for general aircraft, new aerospace materials, aircraft interiors and parts with leading development advantages.

　　While developing aerospace and navigation R&D and manufacturing, Zhenjiang Aerospace Industrial Park is also actively promoting industrial landing, developing navigation operations and cultivating aviation culture, thus forming a relatively complete industrial chain and consumer market, laying a solid foundation for sustainable development.

Near the end of the year, folding screen mobile phones have become a new competition field for mobile phone manufacturers.　

Recently, Huawei released the latest folding screen mobile phone, which once again stirred the market of folding screen mobile phones. Also in the same month, OPPO’s first folding screen mobile phone has also come out.

At the same time, glory, realme and vivo are also developing folding screen mobile phones. In addition, the news that Xiaomi MIX Fold2 is about to be released is also constantly coming out.　

At present, domestic folding screen mobile phones are blooming everywhere. In foreign countries, Samsung, as the head enterprise of folding screen mobile phones, has released three generations of folding screen mobile phones since 2019. According to analysts’ prediction, Apple is also expected to release the first folding screen mobile phone in 2023.

If the prediction comes true, it means that the mainstream players in the mobile phone market will enter the new battlefield of folding screen mobile phones.　

An obvious change is that from the perspective of the third-generation folding screen mobile phone, its price is controlled within 10 thousand yuan, and it is entering the era of parity acceptable to consumers. This also means that the folding screen mobile phone is undergoing technological upgrading and market testing.　

Undoubtedly, with the improvement of technology and the downward price, the penetration rate of folding screen mobile phones will increase. But the real problem is that the folding screen mobile phone is still a niche market, and its sales volume is less than 1% of the whole smart phone market. When will the folding machine really become popular?

In the smart phone market where the market is saturated and the growth is weak, manufacturers are trying to tell a new story. This time, the new story is to buy a folding screen mobile phone at a lower price.　

Different from the previous price of 10,000 yuan, after two years of market development, the price of folding machines has gradually entered the parity stage.　

Whether it is Huawei’s latest folding screen mobile phone, Samsung’s latest folding machine, or the first folding machine released by OPPO, its price has been lowered to around 7,000 to 8,000 yuan, which seems to be more close to the people than before.　

Last week, Huawei released the new flagship folding screen mobile phone P50 Pocket. From the appearance point of view, this folding screen mobile phone adopts the design of vertical folding, and the compact and exquisite appearance also breaks the disadvantages of heavy and horizontal folding in the past.

On the most important axis of folding screen, Huawei P50 Pocket adopts the design of water drop hinge, which has a smaller bending radius than the previous generation.Simply put, with the help of the drop-shaped screen space at the bend, the screen folding can be close to the seamless folding shape.At the same time, the unfolding thickness of the fuselage as thin as 7.2mm can realize a flatter unfolding of the inner screen.　

Unfortunately, the screen cover of Huawei P50 Pocket does not use ultra-thin electronic touch glass (UTG), but continues to use traditional transparent polyimide (CPI). Specifically, UTG is a flexible glass with better performance, while CPI is a plastic material.　

At the same time, as for the core processor, due to the shortage of chips, Huawei P50 Pocket is equipped with Snapdragon 888 chip and adopts 4G network.In this regard, Huawei said that with the support of HarmonyOS Smart Communications, the network experience was not greatly affected.　

Huawei tried to make up for the lack of hardware such as glass and chips with images and batteries. Following the exploration of Huawei P-series images, Huawei P50 Pocket adopts a super wide angle of 120 degrees, and at the same time, fluorescence photography and other modes have also increased the effect of post-shooting. In terms of battery, Huawei P50 Pocket is also equipped with 4000 mAh battery, which supports 40W Huawei super fast charge.　

On the whole, as one of the important players in the folding screen mobile phone market, Huawei is already the head player of domestic folding screen mobile phones.As early as 2019, Huawei launched Mate X, a horizontally folding screen mobile phone, and the launch of the vertically folding P50 Pocket also means that Huawei has completed a double folding layout in the folding screen mobile phone market. Huawei has also become the only brand in the industry to launch three folding forms of mobile phones: outward folding, inward folding and vertical folding.　

Earlier, OPPO released the first folding screen mobile phone OPPO Find N, and at the beginning of this year, Xiaomi also launched the first folding screen mobile phone MIX Fold, and the concept map of MIX Fold2 is also coming out.　

Not only do domestic mobile phone manufacturers keep moving in the folding screen mobile phone market, but Samsung, as the "leader" of folding screen mobile phones, has always regarded it as a heavy bet.In September this year, Samsung officially released the Samsung Galaxy Z Fold3 5G in China, which is Samsung’s third-generation folding screen mobile phone.In addition, Samsung also released a product that folds up and down — — Samsung Galaxy Z Flip 5G.

In the past, the folding screen mobile phone has always been a symbol of high-end. At the beginning, the price of Samsung Galaxy Fold reached 15,999 yuan, and the price of Huawei Mate X reached 16,999 yuan. Even the lowest-priced Xiaomi MIX Fold had a starting price of 9,999 yuan.　

When Xiaomi MIX Fold was launched less than a year ago, its price on the e-commerce platform has dropped by more than 3,000 yuan due to poor sales.　

The trend of head players can better explain the development trend of folding screen mobile phones.　

At present, Samsung undoubtedly occupies an absolute dominant position in the folding screen mobile phone market. According to data from research institute DSCC, Samsung’s market share in the global folding market is as high as 87% in 2020. The price of Galaxy Z Filp 3 with vertical folding scheme reached 7599 yuan, only 60% of that of the previous generation. For this reason, this series has also become the highest-selling folding screen mobile phone in the world.　

For price-sensitive users, the most intuitive change brought about by price reduction is the increase in sales. Samsung’s first-generation folding screen mobile phone Galaxy Fold sold only 500,000 units worldwide. In contrast, the third-generation folding screen mobile phone exceeded 1 million units in one month.　

Compared with the mobile phone manufacturers that have already entered the market, the whole folding screen mobile phone market has been full of smoke.　

Up to now, Samsung has released eight folding screen phones.In terms of mobile phone shipments, in the third quarter of this year, the DSCC report showed that Samsung accounted for 93% of the shipments.In addition to strong mobile phone shipments, Samsung also has the ability to produce screens. According to a recent report by BusinessKorea, a Korean financial media, Samsung plans to increase the output of foldable screens from 17 million to 25 million a year, an increase of more than 40%.　

In China, Huawei, the first to enter the market, is the mobile phone manufacturer with the largest market share. The advent of Huawei P50 Pocket represents that Huawei has started to "walk on two legs" like Samsung, and has two models of horizontal folding and vertical folding.　

Xiaomi’s exploration of folding machine is not very smooth, and its heat dissipation, screen look and feel, creases and other problems have been repeatedly vomited by users, and the price has been falling after listing. OPPO will bet on the cost performance, and launch OPPO Find N with a price of only 7699 yuan, trying to open the market at a low price.　

Generally speaking, whether it is Samsung, which has been deeply involved in the folding screen mobile phone market for a long time, Huawei, which was the first to enter the market, and OPPO, a new player who just entered the market, parity strategy seems to have become the consensus of the industry.

From ten thousand yuan machines to parity machines, the road to price reduction of folding screen mobile phones is not overnight.　

Undoubtedly, in the era of folding screen mobile phone 1.0, the price of folding screen mobile phone has been high, which is a huge consumption threshold. Not many people can afford and are willing to spend a mobile phone with a price of 10,000 yuan. Sales are bound to be limited.　

And if you want to pursue sales and expand the audience, price reduction is the fastest way. However, before the price reduction, mobile phone manufacturers should first consider the production cost, otherwise they may "lose money and earn money".

Among the components of the folding machine, the hinge used to connect the fuselage and provide folding ability can be said to be the core of the folding screen equipment, which determines the strength of the whole fuselage. A hinge is composed of hundreds of tiny parts. Whether the hinge quality passes the standard directly affects the visual effect of the screen crease.　

At present, domestic mobile phone manufacturers, Huawei and OPPO all adopt the method of hinge self-research. Interestingly, at the recent press conference, whose patent is the water drop hinge also caused a confrontation between Huawei and OPPO.　

On the one hand, the research and development cost of hinge technology is high, on the other hand, there is no cost sharing in mass production of mobile phones, which undoubtedly requires a lot of money for the research and development of hinges. At the press conference of OPPO, Liu Zuohu, senior vice president of OPPO, revealed that the cost of this small hinge on Find N mobile phone reached $100, which was 1/10th of the final selling price, while the hinge quotation of other mobile phone manufacturers was generally 200 yuan.　

In addition to the mobile phone manufacturers themselves, upstream suppliers such as Huawei hinge supplier Yian Technology and OPPO hinge supplier Amphenol are also worthy of attention.　

Recently, some investors have asked questions to Yian Technology, a domestic hinge supplier, on the investor interaction platform. The question pointed out that besides supplying Huawei, which customers are Yian Technology? Yi ‘an Technology responded to this, and the company’s liquid metal hinges have been cooperated by five customers.

It is not difficult to see that with the price reduction of folding screen mobile phones and the increase of sales volume, the cost reduction of upstream suppliers is also an inevitable trend.　

In addition to the hinge, the flexible screen is also the key to the competition of folding screen mobile phones.Compared with the straight mobile phone, it is more expensive to adapt to the components in the bending scene. At present, there are two kinds of folding screen mobile phone covers on the market, CPI (colorless polyimide) and UTG (ultra-thin flexible glass). The former can be understood as a plastic material, while the latter is a flexible glass with better performance than AMOLED.　

In the whole folding screen mobile phone market, flexible glass, such as UTG, which has difficult research and development technology and high cost, has been monopolized by giant Samsung, which is also the reason for the high price of folding screen mobile phones.　

Just this year, Samsung opened the supply of external UTG ultra-thin glass, which is also the key to Samsung’s capital to reduce the price of folding machines. The OPPO Find N screen used UTG glass supplied by Samsung.

Obviously, this is a sure-fire business. At present, the folding screen mobile phone is a new trend in the mobile phone market. For Samsung, which is firmly in the top position of folding screen mobile phone sales, cooperation with domestic mobile phone manufacturers can not only increase its own sales, but also share the production cost by increasing sales, and also find new growth curves and broaden income channels.　

At the same time, domestic electronic suppliers are also speeding up the production of UTG glass. Side Semiconductor, Kaisheng Technology, Hui Jing Display and other manufacturers have announced the research and development progress or plans of UTG glass projects this year.　

In the glass cover, the mobile phone display screen is also a difficult problem that needs the homework of mobile phone manufacturers. According to online Insight, the flexible OLED screen of Huawei P50 Pocket was provided by domestic manufacturer Visionox. Data show that in the third quarter of this year, global smartphone OLED panel shipments were about 170 million pieces. Among them, Visionox shipped about 6.3 million pieces, ranking fourth in the world, second only to Samsung Display, JD.COM and LG Display.　

Admittedly, although China companies such as BOE, Vinozin and Rouyu have made great breakthroughs in screen technology in recent years, they still have a long way to go compared with Samsung.　

It is foreseeable that as Samsung opens the supply of UTG glass and the production capacity of domestic suppliers increases, the production cost of folding screen mobile phone screens will further decrease.

Generally speaking, the reduction of production costs of core barriers such as hinges, glass covers and screens directly lowers the market price of mobile phones with folding screens. In the future, with the popularization and mass production of folding screen technology, the price of folding screen mobile phones will be lower.

All along, there have been endless arguments about "folding machines are chicken ribs" and "losing money to make money" in the market.　

Yuan Bo, a senior communication engineer, once told Time Finance that the folding screen is not just needed, but meets the marginalized demand, but it is a symbol of the technical strength of mobile phone manufacturers, and even represents the manufacturers to enter the high-end threshold.　

However, with the gradual maturity of technology, the new folding machines of mobile phone manufacturers are intensively launched, and the superimposed prices are pushed down one after another, and the penetration rate of folding screen mobile phones is expected to accelerate.　

Market research firm Strategy Analytics predicts that in 2025, the shipment of folding screen mobile phones will reach 100 million units.Counterpoint Research, another research institution, also predicts that by the end of 2022, the global shipment of folding machines will reach 18.3 million units.You know, last year, the global shipment of folding screen mobile phones was only 2.8 million. If the agency’s prediction is accurate, the shipment of folding screen mobile phones will increase exponentially in the next two years.　

It is worth noting that Samsung, the head player, has been brave enough to "blood" on the folding screen mobile phone. A few days ago, according to Korean media reports, Samsung will stop the Note series and will take out more cost space to embrace the folding screen mobile phone. In addition to capacity expansion, Samsung also increased the marketing expenses of the folding machine to twice that of the Note series. Samsung also said that the chip supply gives priority to the folding machine, which shows its emphasis on folding mobile phones.　

Although many players bet and the market is promising, it is not easy for folding screen mobile phones to be popularized.　

The problem facing all players is that the price of the folding machine is almost the same as that of flagship machine, but there are still many restrictions on the configuration, which does not meet the standards of flagship machine.　

For example, there are few built-in telephoto lenses, the internal and external screens have not yet been high-brushed, and they can’t meet the high-frequency fast-punching, which have all become constraints for the development of folding machines. At the same time, it is still difficult to achieve unity in the adaptation of screens and applications. At present, the application adapting to folding screens has only increased from 75% to 90%. "The software workload is six times that of ordinary flagship models," Liu Zuohu, senior vice president of OPPO, mentioned at a media communication meeting.　

In addition, the current users of folding machines are still concentrated in the business crowd, and it is even more difficult for new players like OV and Xiaomi to get a slice of the business crowd.　

In this regard, Samsung and Huawei have taken the lead in targeting female users. This time, Huawei’s P50 Pocket has added the function of detecting sun protection. According to Huawei’s official introduction, Huawei Mirror provides an intelligent sun protection reminder function, and uses a hyperspectral imaging system to provide users with sunburn detection services. Earlier, the compact and portable design of Samsung Flip series was also suitable for female users.　

However, the time for folding screen mobile phones to enter the market is still short, and it will take time to test whether they can be bought by female users.　

In addition, when the technical difficulties of hard power such as hinges and screens are still being broken, the high maintenance cost has become a factor affecting the popularity of folding screen mobile phones. According to Huawei’s official website, Huawei’s P50 Pocket costs as much as 4,379 yuan only for screen maintenance, even exceeding some domestic high-end flagship machine. Other repairable components include the motherboard, upper battery cover (including external screen) and rear-view lens, and the prices are 3399 yuan, 579 yuan and 999 yuan respectively.

Obviously, immature technology and imperfect user experience have become a mountain in front of folding screen mobile phone manufacturers.　

Don’t forget that in the field of folding machines, Apple, a heavyweight player in the smartphone market, has not yet finished. If Apple joins, it will become a "killer" player and further expand the overall market of folding machines.Guo Ming Ti, an analyst with Tianfeng International who has been paying close attention to Apple for a long time, believes that the first Apple folding screen mobile phone will be available in 2023, and Apple is ready to increase the shipment of its first folding screen iPhone to 20 million units.　　

However, if Apple also introduces folding screen phones, the competition in the whole market will be more intense, and the pattern may also change.　

There is no new story about smart phones, which is a commonplace topic. It is reasonable that the imagination space brought by folding screen mobile phones attracts mobile phone manufacturers to compete.However, the real problem is that the folding screen mobile phone has been born for three years, but its shipment volume is far less than that of other smart phones, and it is still relatively deserted in the China market. Whether the price reduction tide can make the folding machine catch fire in the China market will soon be answered.　　

　　Cctv newsOn May 17th, with the statements of the three basic operators, Beijing began to enter the era of "100 Mbps broadband". However, some users are still using the old copper broadband, with a slow speed of 4 megabytes and 5 megabytes. However, some users who have installed 20 megabits, 50 megabits or even 100 megabits of fiber-optic broadband at home often have delays in playing online games, and sometimes even ordinary web pages are difficult to open. What stuck the "last mile" in fttp? What caused the "short weight" of broadband speed increase? Come to see the reporter’s investigation.

　　Once "insulated" optical fiber in high-grade residential areas

　　Mr. Pan in Beijing lives in a relatively high-end residential area in the North Fourth Ring Road. The apartment building has its own independent system, and electricity, tap water, gas and communication are all self-contained and provided by the property management. Therefore, the annual fee of broadband used by Mr. Pan is more expensive than that of basic operators, but the broadband rate is only 5 trillion.

　　"I want to open the website and watch a video news." Mr. Pan, who hopes to have a faster network speed, went to the business halls of China Unicom, China Telecom and China Mobile to apply for registration, but was told that the residential area was not covered with optical fiber because the apartment was not allowed to enter.

　　A similar situation is not uncommon in other communities. In some communities, there is only one broadband service provider to choose from, and even the advertisements of other broadband companies are hard to see. However, the only broadband service provider is often slow and expensive. Mr. Pan wondered that the optical fiber had been laid at the bottom of the residential building, but it was stuck because of this "last mile". Who will protect the rights of the residents?

　　100 Mbps broadband WeChat voice chat will be dropped.

　　"When we register our children online, we are particularly anxious. A fairly simple webpage can’t be opened." Mr. Hong, a citizen, uses the 50-megabit-rate fiber-optic broadband annual service handled by Great Wall Broadband at home. However, after using it for one year, Mr. Hong felt that this 50-megabyte bandwidth was more like an "embroidered pillow".

　　Mr. Jiang has just moved to a new home this year. Last month, he installed 20 megabits of "Dr. Peng" broadband, and the annual subscription fee was 1180 yuan. He said that he originally wanted to install the broadband of a big telecom operator, but the reply he got was that the community was not covered yet, so he could not go to fttp. "The network speed is very unstable. Now our community has only occupied about 40% of users, and playing an online game will get stuck. What if everyone moves in? " Mr. Jiang is deeply anxious about this.

　　Mr. Wang, who lives in Yizhuang, said that the 100-megabit fiber-optic broadband in his own community would suddenly fail to open ordinary web pages, or be inexplicably disconnected while playing games, and there have also been cases where voice chat on WeChat suddenly broke. Mr. Wang showed several times the value of online speed measurement. In the case of using the telecom speed measurement web page, the fastest time, the tested bandwidth was only 26 megabits, which was only a quarter of the 100 megabits rate.

　　remove a doubt

　　Obstruct operators from entering the market for the benefit of property.

　　According to Beijing’s informatization development plan, the free transformation of "light entering copper retreating" has been started in the whole city since 2011. Up to now, most of Beijing’s urban residential areas and rural areas have realized optical fiber to the building or fttp. However, there are still a few residential areas that can’t go home for "optical reform" for various reasons.

　　According to an operator, some residents are unwilling to carry out optical fiber transformation in the residential areas that cannot be "light-reformed" at present, but more because property companies or property rights units obstruct operators from entering the market. "Of course, the reason for obstruction is for the benefit." According to a person familiar with the matter, in addition to admission fees, some property companies are not satisfied with collecting money at one time, and put forward new requirements such as broadband revenue sharing and collecting maintenance fees every year.

　　In this regard, in 2016, the three departments of Beijing jointly issued the Notice on Promoting the Implementation of residential broadband Access for Property Management. It stipulates that real estate development enterprises or property service enterprises shall not sign monopoly or exclusive broadband operation agreements with others. On the premise that the infrastructure such as the equipment room has multiple accesses, the realty service enterprise shall try its best to meet the needs of the owners, at least ensure that more than three broadband operators have equal access, and disclose the relevant information of broadband access to the owners in a prominent position in the community.

　　Too many users will lead to insufficient bandwidth.

　　"The bandwidth mentioned by telecom operators is all theoretical values." A telecom expert said that in actual use, the download speed is lower than the theoretical value. Generally speaking, fluctuations in the range of 75% to 90% of the theoretical value can be regarded as normal. There are two main reasons why home users often feel that the network speed is not up to standard: the hardware facilities are not matched, or there are too many sharing users.

　　Experts explained that in order to make full use of broadband resources, increase broadband revenue and reduce costs, operators will calculate an online ratio and choose how many users to configure on this basis. "In order to seize more business, small operators often attract customers at very low prices, and then configure more users regardless of the online ratio, resulting in insufficient broadband."

　　Lack of authoritative third-party speed measuring mechanism

　　How do you know how much "moisture" is mixed in the rate of home broadband? Just like Mr. Wang, a citizen, in practice, many users will choose to use speed measuring software to measure speed. However, the third-party speed measuring software on the network, not only the speed measured by each speed measuring software is different, but also the same software often measures different speeds.

　　 The Ministry of Industry and Information Technology has said that the local communication administrations will cooperate with third parties to measure the speed of "fixed broadband access rate" and release it to the public. But up to now, there is no authoritative third-party broadband speed measuring agency in China.

　　On March 18th, Wang Jiequn, Party Secretary and Director of Beijing Radio and Television Bureau, led a team to () Group Co., Ltd. for investigation. On behalf of the company, Xie Guangcai, director and executive vice president of the company, made a report and exchange on the company’s situation, contents and technological development in the field of network audiovisual.

　　Director Wang Jiequn and his party visited the Chinese online exhibition hall, listened to the reports of Chinese online on micro-short drama business, short drama going to sea, IP derivative, AIGC big model, etc., and learned about the problems and demands of the enterprise in detail, and had full exchanges with responsible comrades of relevant departments of the company.

　　Director Wang Jiequn summed up and put forward hope for the development of the enterprise. First, explore the transformation of excellent IP movies and TV plays. Many scripts of excellent TV dramas and miniseries come from online literature. Chinese online should give full play to its advantages, sort out and explore excellent IP, and also contribute to the development of the industry. Second, pay attention to creating fine content, and pay more attention to the depth of works, the spread of stories and the value of culture. The third is to give full play to the empowerment of science and technology to provide strong support for the fine and high-quality development of micro-short plays. Fourth, the Radio and Television Bureau should provide good services and actively assist in solving the difficulties of enterprises within the scope of policies. On behalf of the company, Xie Guangcai thanked the Municipal Bureau of Radio, Film and Television for its guidance and concern, and said that he would continue to play the leading role of digital content enterprises and promote the healthy development of the industry.

　　Wang Zhi, deputy director of the party group of Radio and Television Bureau, Zhang Nan, director of the office, Xia Fei, director of the network audio-visual management office, and Xia Chao, deputy director of the network audio-visual management office, accompanied the investigation. Yang Ruizhi, Vice President and Chief Operating Officer of Chinese Online, Li Kai, Senior Vice President, and Wu Jiang, Chief Technology Officer attended and reported the exchange.

() According to the data center, () on March 18th, it was bought by financing of 7,489,600 yuan, accounting for 8.36% of the purchase amount on that day, and the current financing balance was 71,679,700 yuan, accounting for 6.75% of the circulating market value, exceeding the historical 50% split level.

Note 1: If the financing balance increases for a long time, it means that the investor’s mentality is biased towards the buyer, and the market is a strong market with strong popularity, otherwise it is a weak market.

Note 2: Buying amount = actively buying extra large single amount+actively buying large single amount+actively buying small single amount.

At present, mobile phone manufacturers including Samsung, Glory, Xiaomi, OV and Meizu have successively entered the field of AI mobile phones, and a new round of demand for mobile phone hardware is being set off, especially for related chips.

On March 18th, Qualcomm, an American chip manufacturer, held a new Snapdragon flagship product launch conference in Beijing, announcing the launch of the third generation Snapdragon 8s mobile platform. National business daily reporter noticed on the spot that in terms of basic performance architecture, Snapdragon 8sGen3 is still equipped with Qualcomm KryoCPU, which inherits the same CPU architecture as Snapdragon 8Gen3, including a super core with a main frequency of 3.0GHz, four performance cores with a main frequency of 2.8GHz and three efficiency cores with a main frequency of 2.0GHz.

However, from the positioning point of view, Snapdragon’s 8sGen3 is slightly lower than Snapdragon’s 8Gen3 released in October last year, which means that in addition to high-end flagship products, some mid-range mobile phones will also have AI functions this year.

Ma Xiaomin, Senior Director of Product Market of Qualcomm Technology Company, introduced that in terms of generative AI, Snapdragon 8sGen3 supports the multi-modal generative AI model running on the end side, and the model parameters are up to 10 billion. The person in chMetarge of Qualcomm also said that the chip supports a wide range of AI models, including Baichuan-7B, Google GeminiNano, Llama2, and ChatGLM of Zhipu AI. In terms of images, Snapdragon 8sGen3 supports real-time semantic segmentation of photos and videos, and it is more accurate to identify and segment objects and scenes.

Referring to the parameters of the end-side model, Guo Tianxiang, a senior analyst of IDC China, said to the reporter of national business daily through online analysis: "At present, the 10 billion end-side model (for consumers) will not be improved and upgraded in a subversive way. Next, more applications will need to use the model of cloud measuring 100 billion or even more parameters. However, the improvement of model parameters will become part of the competition of AI mobile phones in the future, but more importantly, it is necessary to actually improve the consumer’s experience from the usage scenario. "

Traditionally, every time Qualcomm releases its flagship chip, it will be favored by major Android phone manufacturers. At the press conference, mobile phone manufacturers including Glory, iQOO, realme Realme, Redmi and Xiaomi indicated that they would adopt Snapdragon 8sGen3, and commercial terminals are expected to be available in the next few months.

In recent years, it has become the biggest goal of Qualcomm to promote the production AI to reach all kinds of terminals, including a wide range of consumer electronic products. In January of this year, Qualcomm CEO An Meng shared how AI will profoundly affect the way people interact with terminals. "The revolutionary significance of generative AI is that the information on the terminal can help AI become a ubiquitous personal assistant, promote the integration of mobile phones and the cloud, and bring new ways of interaction to smart phones. There are also many amazing AI use cases in major mobile phone brands. Will be deployed in mobile phones in 2024; Let the car become a new computing space and support users to really talk to the car. "

According to him, the Snapdragon platform has now supported more than 40 different models, and the generative AI application will become a reality in the new terminal products launched this year.

In addition to Qualcomm, another mobile phone chip manufacturer, MediaTek, has also launched a mobile phone SOC chip with AI computing power-Tianji 9300, which provides the underlying performance and technical support for end-to-end generative AI. For example, the SDXLTurbo engine of Wenshengtu can generate images in real time according to the text input by users; The video generation capability of Diffusion can generate continuous videos according to the text or pictures input by users, and supports various animation styles.

On the terminal side, major mobile phone manufacturers have announced artificial intelligence plans, introduced customized versions of operating systems, and developed self-generated AI models to seize the wave of AI mobile phones. IDC predicts that in 2024, the global shipment of a new generation of AI mobile phones will reach 170 million units, accounting for about 15% of the total smartphone shipments. Among them, in the China market, with the rapid iteration of new chips and user usage scenarios, the share of the new generation of AI mobile phones will rise rapidly after 2024, reaching 150 million in 2027, with a market share of over 50%.

In the view of Guolian Securities, with the release of a number of new AI mobile phone models and the improvement of user experience brought by AI, smartphone sales are expected to return to the rising cycle.

　　▲ The suspect Yao Mosai identified the scene.

　　In the night, several men came to the cemetery with shovels and crowbars. Some people shoveled, others let out the wind, and others went down to light candles … … Recently, this scene really happened in Dangui Village, Fengyu Town, ziyang, Sichuan.

　　On November 27th, the Red Star journalist learned from the Yanjiang Branch of Ziyang Public Security Bureau that Zeng, a native of Ziyang involved in the case, had read the tomb-robbing novel before and met three Anhui men through a QQ group called "Notes on Tomb-robbing in the North School". After knowing each other, they met and stepped on the spot in Dangui Village, and finally jointly pried open an ancient tomb. In the early morning of November 23, after digging out a porcelain pillow, they were stopped by villagers and police on the spot.

　　At present, four people have been criminally detained by the police and the case is under further investigation. According to the preliminary appraisal by Yanjiang Cultural Management Institute, the stolen ancient tomb was built in the late Qing Dynasty. The specific age and whether the stolen porcelain pillow is a cultural relic are waiting for further appraisal by the cultural relics department at a higher level.

　　▲ The police investigated on the spot.

　　Found:

　　The ancestral grave was "loosened"

　　The villagers suspected that someone was going to rob the tomb.

　　Fengyu Town is located in Yanjiang District, ziyang, bordering Zizhong County, Neijiang City. In Dangui Village, Fengyu Town, the family of villager Han has been multiplied for at least several generations. On the morning of November 22, at the age of 71, he suddenly received a phone call saying that one of his family’s ancestral graves seemed to have been "loosened" recently.

　　This ancestral grave of the Han family is located in a bamboo forest, and the linear distance from the nearest house is less than 20 meters. To this end, he rushed to the scene and found that the soil on the tomb had been dug in many places, but the stone on the tomb door had not been opened. "This place is a main road, and no one has seen anyone come during the day." Han suspected that someone was eyeing his ancestral grave, wanted to rob the tomb, and judged that those people would come again.

　　Due to the age, the ancestral grave door of the Han family has been buried by mud, leaving only a stone engraved with inscriptions exposed. "People who are not around here may not think it is a tomb." Han also said that he had learned from his grandfather that someone in his family ancestors was a juren in the Qing Dynasty and was buried in this tomb after his death.

　　▲ The suspect Zeng identified the scene.

　　Grave robbery:

　　Learning novels, lighting candles in the tomb

　　Four people ganged up to rob the tomb and were arrested one after another.

　　In order not to alarm the grass, on the evening of November 22, Han and the local president and others hid in the citrus forest behind the cemetery in advance to "wait for the rabbit."

　　At 10 o’clock that night, Han heard someone walking around the cemetery, but did not see the lights. "We are far apart, and we are not sure how many people there are." Han and others stayed until the early morning of the next day, during which someone’s phone rang. Fearing that the grave robbers would escape early after hearing this, they immediately called the police station to tell them about it.

　　"I caught three people at that time." Chen Lin, a policeman from Fengyu Police Station of Yanjiang Branch of Ziyang Public Security Bureau, said that after they arrived at the scene, they arrested three men, one of whom was found by the police while hiding in the ditch. Afterwards, Zeng, who was familiar with the terrain and fled, realized that he could not escape after all and surrendered himself on November 23.

　　▲ The suspect lit a candle in the northwest of the tomb according to the routine in the tomb robbery novel.

　　Zeng is a native of Yanjiang, and the other three arrested Yao Mosai, Cong and Yao Mouwei are from Anhui. According to the police, that night, after opening the tomb, the four men studied the bridge in the novel, lit a candle in the tomb, and then stole a porcelain pillow from the tomb. However, the police who arrived soon caught it. In the escape, Yao Mosai broke the porcelain pillow.

　　At present, according to the preliminary appraisal by the Cultural Management Institute of Yanjiang District, ziyang, the stolen ancient tomb was built in the late Qing Dynasty. However, the specific age and whether the porcelain pillow is a cultural relic are waiting for further identification by the cultural relics department at a higher level.

　　▲ Porcelain pillow stolen by the suspect from the tomb and broken when fleeing.

　　Account:

　　After reading tomb-robbing novels, join a group to get to know each other.

　　Several people took risks to repay the loan

　　Why did three Anhui men get in touch with Zeng of Ziyang Yanjiang?

　　According to Zeng’s account, he had joined a QQ group named "Notes on Tomb Robbery in the North School" because he had read the novel of tomb robbery, and posted photos of suspected ancient tombs seen near his home in the group. Soon after, Yao Mosai took the initiative to add Zeng as a friend and said that he was "very interested" and wanted to come to him, promising to let him "take the big head" if he dug up something.

　　▲ The suspects get to know each other in the group of "tomb-robbing novels" and discuss how to commit crimes and divide the spoils.

　　After investigation by the police, on November 19th, Yao Mosai invited Yao Mouwei to drive from Anhui to Fengyu Town. After they met and stepped on the spot, they bought shovels, crowbars, flashlights, candles and other tools in the town, and started to work on the evening of November 20th. The four people have a clear division of labor. Zeng is responsible for watching the wind, Yao Mosai is responsible for positioning, and Cong and Yao Mouwei are responsible for mining. However, due to the lack of preparation tools, the four men dug for two consecutive nights and did not pry open the stone on the tomb door. On the evening of November 22, the four men who started for the third time finally pried open the tomb door to carry out the theft, and were arrested one after another.

　　When talking about why he took risks, Yao Mosai told the police that several of them were short of money. He also borrowed about 8,000 yuan a month, and it took several thousand yuan to repay the loan from a certain person and Yao Mouwei every month.

　　At present, four people have been criminally detained by the police and the case is under further investigation.

　　CCTV News:Pretending to be an acquaintance to borrow money, pretending to be a public security bureau, a procuratorate or a court officer to investigate a case, and hiding a Trojan link &hellip in short messages and QR codes; … These tricks must have made everyone immune, but do you know? Some telecommunications services that you have never heard of have also begun to become new traps set by scammers!

The mobile phone was locked and more than 50,000 yuan was stolen.

　　When he woke up, Mr. He in Shenzhen found that his mobile phone was locked. At the same time, a shopping platform account was stolen by strangers. Criminals used white bars to spend and apply for loans, and robbed more than 50,000 yuan overnight.

　　Later, Mr. He discovered that his mobile phone had been taken over by a strange number. The short message from the operator shows that this is a business to add a secondary number, and Mr. He’s mobile phone number was added as a secondary number by criminals. When the secondary phone is turned off, all short messages will be received by the primary phone, and criminals will receive Mr. He’s short message verification code during this period, and then commit crimes.

"Subnumber" ≠ "kinship number"

　　Without an ID card, a bank card or even a real name, the money is gone. What the hell is a minor number?

　　Many people think of "family number" at first, but "deputy number" and "family number" are not the same thing.

　　Family number usually refers to the phone bill package opened by different owners and different numbers in order to make calls between them cheaper, and the secondary number is the "one card with many numbers" service provided by operators. On the basis of not changing mobile phones and SIM cards, users can add up to three real mobile phones as secondary numbers. The main and auxiliary numbers can stand by at the same time, and you can freely choose any number to dial, answer the phone and send and receive short messages as needed.

Don’t reply to text messages too casually.

　　Then, how did Mr. He’s mobile phone number become the "secondary number" of criminals?

　　Reduction of criminal modus operandi

　　Step 1: Buy materials.Criminals buy leaked names, bank card numbers, ID numbers and reserved mobile phone numbers online, commonly known as "four big pieces".

　　Step 2: Fishing.Criminals apply to the users who have mastered the bank card information, initiate the business application of binding the sub-number, and find the target of the crime by casting a net widely. Once you reply by mistake, you are hooked.

　　Step 3: Forced shutdown.Because the main number can only take over the SMS when the secondary number is turned off, criminals usually use two means at this time. One is to use SMS bombing to force the target to turn off the mobile phone, and the other is to use the mobile phone cloud service to remotely operate the mobile phone.

　　Step 4: White Wolf with Empty Gloves.Using the SMS verification code received by the main number, criminals ransacked the online shopping account bound to the mobile phone number.

　　Patterns are stacked, and it is impossible to prevent them! For this kind of fraud, after receiving all kinds of SMS notifications, you must read the content of the SMS clearly and do not reply at will.

"SMS custody" business is also not very secure.

　　After the SMS storage service is opened, you can save your mobile phone messages on the server of the operator. Now, many mobile phone manufacturers’ cloud services are doing the same thing. However, this is a hidden danger function.

　　Case review

　　One morning, Miss Ding saw two short messages from banks and mobile phone operators on her mobile phone, which were sent at 3:43 am and 4:12 am respectively. As soon as the account is checked, the balance of more than 100,000 yuan will be zero overnight! Not only that, Miss Ding also suffered a credit card theft and was "applied" for a bank universal loan of 70,000 yuan.

　　How on earth did all this happen?

　　Reduction of criminal modus operandi

　　Step 1: Hit the database to get all kinds of account information.The so-called "library collision" means using software to try a high probability digital sequence. Using this simple and rude method, the user’s network identity, online banking account number, mobile phone business hall and other accounts can be seen at a glance. Insiders said: "The speed of library collision is very fast, at least thousands per minute. If some good equipment is used, the efficiency is higher and the success rate is above 50%."

　　Step 2: Open SMS storage and SMS interception services to obtain verification code.This is the most critical step. After the opening of this service, the dynamic verification code to ensure the safety of landing has successfully become the bag of criminals.

　　Step 3: Open the physical SIM card.At this point, criminals can pretend to be victims and apply for 4G card replacement service in the online business hall. For the convenience of the people, some operators can express the card directly to the designated address.

　　By intercepting short messages and copying SIM cards, fraudsters can "do whatever they want".

　　As we all know, many important services rely on mobile phone authentication. If you back up the SMS to the server synchronously, it will increase the exposure opportunity. Once the service password of the online business hall is stolen, or the login permission of the cloud service is stolen, it is equivalent to "swimming naked".

The loopholes in the unpopular business are targeted by scammers.

　　The "Research Report on the Trend of Online Fraud in 2016" released by the anti-fraud reporting platform "Hunting Network Platform" proposes that since 2016, online fraud has mainly shown several obvious characteristics:

　　Mobile phone cards have become new theft targets;

　　Jump to the phishing website by using short URL and weiyun sharing link;

　　Well-known recruitment websites and voice platforms for open recruitment;

　　A phishing website that is difficult to distinguish between true and false;

　　The implementation of precision fraud;

　　Fraud professionalism is getting higher and higher;

　　Using loopholes in new business and unpopular business to commit fraud;

　　Use cloud disk and synchronization software to steal information.

　　Among them, the loopholes in mobile phone cards and unpopular business are mentioned.

　　Security experts suggest that we should develop good online habits, don’t click unfamiliar links, don’t fill in our personal information in the website interface with unknown security, and regularly modify the password of social accounts to avoid information such as mobile phone contact information being leaked; Improve safety awareness, develop good habits of using mobile phones, and avoid being infected by mobile phone viruses.

　　BEIJING, Beijing, July 28 (Wu Tao) On the 27th, the three major operators announced that they would completely cancel the domestic long-distance roaming charges for mobile phones from September 1. This means that domestic roaming charges for mobile phones that have been implemented in China for more than 20 years will become history. Who will benefit after cancellation? What impact will it have on operators’ operations? Zhongxin. com interviewed relevant experts for this purpose.

　　Long-distance roaming charges for domestic mobile phones will be cancelled after more than 2 years.

　　On July 27th, Yang Jie, Chairman of China Telecom, announced at the 9th "Tianyi Intelligent Ecology Expo" that from September 1st, China Telecom will completely cancel the domestic long-distance roaming charges for mobile phones, which is one month ahead of the plan at the beginning of the year, and it is expected to benefit 80 million users.

　　Subsequently, China Unicom and China Mobile announced that they would completely cancel the domestic long-distance roaming charges for mobile phones from September 1st, which was implemented one month earlier than originally planned on October 1st. On March 6 this year, three basic telecommunications companies said that they would officially cancel the long-distance roaming charges for domestic mobile phones from October 1.

　　The reporter checked the information and found that roaming charges can be traced back to the 1990 s and have already been generated during the mobile phone period. In 1990s, China set up a "roaming fee" similar to tariff for mobile phones used across regions.

　　This year, the three major operators have already begun to cancel the long-distance roaming charges of domestic mobile phones in advance. On July 25, Zhang Feng, spokesperson and chief engineer of the Ministry of Industry and Information Technology, said that regarding the cancellation of domestic long-distance roaming charges for mobile phones, the Ministry of Industry and Information Technology continued to push the three basic telecommunications companies to speed up their work in accordance with the principle of ensuring that the work is in place and striving for early implementation. "The three companies are making every effort to promote system transformation and other related work, and strive to achieve their goals ahead of schedule."

　　The reporter noted that the official plan to cancel the domestic roaming fee for mobile phones began in 2015. On July 6, 2015, the relevant person in charge of the Ministry of Industry and Information Technology said at the press conference on "speeding up and reducing fees" that "the Ministry of Industry and Information Technology is currently studying and exploring the possibility of canceling roaming charges."

　　What is the impact on ordinary consumers?

　　According to the data of the Ministry of Industry and Information Technology, by the end of June 2017, the total number of mobile phone users in China reached 1.36 billion. Who will be affected by the cancellation of domestic long-distance roaming charges by the three major operators? Will the user’s phone bill drop?

　　Xiang Ligang, an expert in communication industry, said in an interview with Zhongxin. com that the users who really benefit from it are mainly some old users, and the impact on ordinary consumers is actually very small.

　　"There are two main reasons: First, many new packages sold by the three major operators are ‘ Long-term market integration ’ (Long-distance, local calls and roaming are the same price), and these packages do not care about long-distance roaming; Second, for a period of time, a large number of users are converted into 4G users at high speed, that is, from old users to new package users. " Xiang Ligang said.

　　There are data to support this view. According to the latest data from the Ministry of Industry and Information Technology, in the first half of this year, 2G and 3G users continued to switch to 4G users, and 4G users maintained steady growth, with a cumulative net increase of 118 million, reaching 888 million, accounting for 65.1% of mobile phone users.

　　Ma Jihua, an analyst in the telecommunications industry, analyzed in an interview with Zhongxin.com, "There is one kind of users who will benefit, that is, users who use local packages may spend less in the future, but they will not get much light, because the reason why they use local packages is because the demand for long-distance roaming is not great."

　　What is the impact on the three major operators?

　　What impact will this policy have on the three major operators after its implementation? Will its income decline? According to Xiang Ligang’s analysis, the impact is very small. Long-distance roaming charges are originally a management tool of the three major operators. Now, the voice business income of the three major operators is shrinking, and the proportion of total revenue is also decreasing. Therefore, the cancellation of long-distance roaming charges has little impact on the income of the three major operators.

　　Ma Jihua holds the same view. He believes that although the policy will have a little impact on the income of the three major operators, it is not too big. "The three major operators can fully withstand it, and the voice services of the three major operators have also continued to decline. In the future, the income will mainly depend on traffic."

　　According to the data of the Ministry of Industry and Information Technology, from January to April this year, the voice business income of the three major operators accounted for 19.6% of the telecom business income. By the middle of the year, that is, from January to June, the proportion dropped to 19.4%, down 7.1 percentage points from the same period of the previous year.

　　Contrary to this, the traffic revenue of the three major operators is growing rapidly. In the first half of the year, the revenue of mobile data and mobile Internet services of the three major operators reached 274.6 billion yuan, up 29.6% year-on-year, accounting for 42.6% of the revenue of telecom services, driving the revenue of telecom services to increase by 10.3 percentage points.

　　Mother-in-law’s tattooing is a long-standing and educational story among the people. According to a gentleman on the phone, it is acceptable for Yue Fei’s descendants to remarry his ex-wife Liu, and they can’t accept it without her mother-in-law’s tattoo. In fact, purely emotionally, why am I willing to deny this story that still inspires China people’s patriotism? But unfortunately, there is no account of this matter in the Chronicle of the King of Hubei written by Yue Fei and Sun Yue Ke. The following is the only note in Volume 9 of the Nazi Compilation of the Kingdom of Hubei:

　　The first minister was filial by nature, and he was troubled by the northern territory. His mother ordered him to join the army to serve the country, and he could not bear it. After repeated interest, I had to stay with my wife and foster mother and cross the river from Emperor Gaozong alone. Hebei is trapped, lost and stolen, and the voice is completely separated. I have been asking for a visit day and night, but I haven’t got it for several years. Russia has a visitor from my mother, saying, "And my mother sent a message: Speak for me, encourage the holy son of heaven, and don’t think of my sister." I secretly sent people to meet him, but I was blocked by the hustle and bustle. Eight out of ten people went back and forth, and then returned. My first minister was grateful and wept, and thanked me for being unfilial.

　　It can be seen that although my mother-in-law is an ordinary peasant woman, she is deeply aware of the righteousness, and it is enough to be revered only in terms of this record. The original record of Yue Fei backstab’s four words "Dedicated to Serving the Country" can be found in The History of Song Dynasty, Volume 380, Biography of He Zhu, but during the interrogation of Yue Fei:

　　Flying naked and showing the back, the back has the four words of "serving the country faithfully" of the old Nie, which goes deep into the skin.

　　This shows that the tattoo on Yue Fei’s back is years old. Of course, the two most original records quoted above cannot provide proof of mother-in-law’s tattooing. Reasonably, my mother-in-law, as an ordinary peasant woman, was generally afraid of not being able to read, and tattooing at that time was a special skill. In the eighth chapter of The Water Margin, it is said that Lin Chong was "stabbed far away from the military state" and "called a writer and stabbed his cheek". The twelfth time that Yang Zhi was sentenced, he also "called a literary craftsman and stabbed two lines of gold seals, overlapping with the left-behind department of Beijing Daming Mansion to serve as an army", indicating that not everyone in the Song Dynasty had the skill of tattooing people casually.

　　Even in terms of ancient romance novels or operas, Yue Fei’s Breaking the East Window, which was compiled in Volume 11 of Quanyuan Opera, was analyzed by the editor, and there were traces of modification by the Ming Dynasty. His 18th poem describes that Yue Fei was interrogated on Wednesday and replied: "If Yue Fei had this matter, would he be willing to stab people in the skin with the words’ serving the country faithfully’ since childhood?" It is difficult to judge whether this passage is the original words and phrases of Yuan opera or the reviser of Ming opera, but it also shows that Yuan opera may still follow historical records. Since then, it may have been written by Yao Maoliang when Chenghua was in the Ming Dynasty. (The sixteenth legendary story of "Loyalty" describes the same plot. Yue Fei replied: "Your honor is on the top, and Yue Fei has been engraved on his body with the words’ serving the country faithfully’ since he was a child. Please examine it carefully."

　　There is still no story of mother-in-law tattooing in the Romance of the Great Song Dynasty published by Ming Jiajing. Volume 1 of the novel only says that Yue Fei was in Jingkang, and when he saw Hu Ma, Song Bing cowered, and all the heroes in the countryside came, he went into the mountains to be the enemy. Fei said,’ A gentleman is not famous in the history books, but a thief who steals from the dog and lives in the world, is it ok?’ It is the four words of’ loyalty to the country’ that are tattooed on the back to show the meaning of not being evil. " Volume 7 of the novel says, "Yue Fei takes a confession, then splits his clothes and turns his back. Compared with Wednesday, there are four big black words, which are deeply rooted in people’s skin."

　　At the end of the Ming Dynasty, Feng Menglong wrote the legend of Jingzhong Banner, and his second fold, Yue Hou Nie Bei, compiled the story of Yue Fei asking Zhang Xian to stab him in the back. The excerpt is as follows. Sheng (Yue Fei) said, "Zhang Xian, you brought a knife and impressed on my back the words’ serve the country faithfully’." At last (Zhang Xian) said, "I’m afraid of your master’s pain." "I was furious," he said, "Alas, I am not afraid of Yue Fei’s death, so I am afraid of pain!" At the end, he said, "In that case, the villain is bold!" At the end, he said, "It’s finished." The student said, "Let me forget it." "At the end, I should be introduced by Nie, and the outside (pale head) and the students should be dressed." At the end, I said, "Sir is determined to serve the country, so why bother to endure this pain?" The student said, "Zhang Xian, all courtiers now flatter the Lord and forget the monarch behind his back. I’ll engrave these four words on my back today to wake up those who forget the Lord and betray the monarch and ask him to look back." It seems that the author deeply felt that "civil officials love money, military officials cherish death" in the late Ming Dynasty, and made this remark.
