Details of colorful Z590M motherboard (1);

The protagonist of this test is CVN Z590M GAMING FROZEN V20 from Colorful, which is an M-ATX architecture motherboard with Intel Z590 chipset. Different from CVN Z590M GAMING V20, the motherboard with the FROZEN logo adopts the main color of white, which is suitable for building a pure white computer host with various white computer accessories.

Although the positioning of the motherboard is low-end, focusing on the people-friendly price, it is still necessary to improve the material specifications as much as possible in the power supply system to ensure the stable operation of the processor and allow users to simply overclock.

The CPU external auxiliary power supply of the motherboard is a single 8Pin.

The motherboard adopts the power supply design of 5-phase times 10-phase +2-phase. The 5-phase power supply has reached the CPU core power supply design equivalent to 10-phase through the phase doubling chip, and the nuclear display is a separate two-phase. Unfortunately, the above logo is batch, so the specific specifications cannot be found.

The PWM power supply is RT3609BE, which is a dual-channel CPU PMW power supply controller of Ruiyu, and it can support 6-phase (CORE VR)+2-phase (AXG VR) power supply design at most.

The heat dissipation module of the motherboard power supply system is composed of two parts, one of which is connected with the I/O panel through screws, and the other is independent. The total weight of the two aluminum blocks is 240g g..

In terms of memory, the motherboard supports DDR4-4266MHz(OC) memory at maximum, and X.M.P supports DDR4-3733MHz at maximum. The maximum capacity of four memory slots is only 128GB for dual channels, and the maximum capacity of a single memory slot is 32GB.

§Attention today

75 years ago today, Shanghai was liberated.　

※　To commemorate the 75th anniversary of Shanghai’s liberation, yesterday morning, the "Theme Report on Celebrating the 75th Anniversary of Shanghai’s Liberation" was held in the auditorium of Shanghai University, under the guidance of the Propaganda Department of Shanghai Municipal Committee and the Shanghai Double Support Office, and co-sponsored by Shanghai Yongjunyoushu Foundation, Shanghai University and Jiefang Daily.

The report fully reviewed the whole process of the liberation of Shanghai, and many descendants of heroic martyrs who liberated Shanghai took the stage to share touching stories. Representatives of students from Shanghai University, families of military martyrs from Jing ‘an and Baoshan District, and social support units for supporting the army and their families attended the report meeting.

Everyone has said that today’s peaceful and happy life is hard-won. We should respect heroes, forge ahead, inherit the red gene and build a glorious city together.

The Shanghai campaign won a total military and political victory.

To understand the significance of the important historical event of Shanghai liberation 75 years ago, we must first understand what happened in that year.

At the report meeting, Zhang Yun, a professor at the School of Political Science of National Defense University and honorary president of the Shanghai Society for the History of the Communist Party of China, gave a keynote speech entitled "An Important Battle Related to China’s Historical Destiny-Celebrating the 75th Anniversary of the Victory of the Shanghai Campaign", giving a detailed introduction from three aspects: the basic concept of the Shanghai Campaign, the way to win the Shanghai Campaign and the significance of the victory of the Shanghai Campaign.

The Battle of Shanghai lasted for 16 days from May 12 to May 27, 1949. It was the last battle of the Battle of Crossing the River, also known as the last battle of the Battle of Beijing, Shanghai and Hangzhou. It is a large-scale urban battle in the strategic pursuit of the People’s Liberation War, and it is also an important battle related to the historical destiny of China.

"In this battle, the People’s Liberation Army seized a large number of weapons, equipment and military supplies, handed Shanghai into the hands of the people completely, won a total victory in military and political affairs, and created a miracle in the history of war." Zhang Yun believes that the main way for the People’s Liberation Army to win lies in four aspects: brilliant strategic guidance, orderly pre-war preparation, heroic urban attack and unique winning model.

Zhang Yun pointed out that the fate of Shanghai is actually a microcosm of the historical fate of modern China. Since modern times, the rise and fall of the Chinese nation, the safety of honor and disgrace have always been closely related to this city. The liberation of Shanghai is a change of the times and a turning point in history. In addition, the victory of the Shanghai campaign has profound and extensive contemporary significance, of which the most fundamental and crucial one is that those who win the hearts of the people win the world.

"In the new historical period, we must follow the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era,’ Jiangshan is the people and the people are the mountains’ and forge ahead on the journey of the great rejuvenation of the Chinese nation." Zhang Yun said.

The story of martyrs is touching.

The liberation of Shanghai was exchanged for the blood of revolutionary martyrs. During the 16-day battle, PLA soldiers braved the bullets and marched forward bravely, and more than 24,000 officers and men were gloriously injured, and 7,613 officers and men gave their lives. Three descendants of heroic martyrs were invited to the report, and they told touching stories of their ancestors who fought bloody battles and liberated Shanghai.

The 87th Division of 29 army, 10th Corps of the Third Field Army, fired the first shot of Shanghai’s liberation, and then attacked Yuepu Town from the western front. Zhang Qiangsheng son of the general Zhang Xiaoyu, commander of the 87th Division, recalled that May 14th was a crucial day for the battle order to capture Yuepu Town. Zhang Qiangsheng, deputy commander Lin Naiqing and chief of staff Ye Keshou went to the front positions respectively to learn about the situation and plan and organize the second storm. By dawn on the 15th, the 87th Division occupied Yuepu Town, realizing the strategic intention of the Central Committee.

In the fierce battle in Yuepu, Hu Wenjie, head of the 259th Regiment of the 87th Division, was unfortunately shot while commanding the battle and died heroically. He was the highest-ranking commander of our army who died in the battle of Shanghai. Twenty-two days after Hu Wenjie’s death, his youngest son, Hu Jijun, was born.

"Father’s combat is characterized by being forward and sinking. Before the war, he personally approached reconnaissance and reconnaissance of the terrain. He tried to observe and command as close as possible in the battle and adjusted in time according to changes in the enemy’s situation." Hu Jijun said that in the battle on May 14th, Hu Wenjie’s hand-held carbine personally led the troops to continue to attack the enemy positions, and finally opened a breakthrough to drive the enemy out of Yuepu. Later, he organized troops to build fortifications and deploy defenses overnight. "According to comrades’ memories, my father didn’t sleep for more than 70 hours in his life, and he spent it in fighting with the enemy and bullets."

From January to May, 1949, there were 100 local martyrs who died for the liberation of Shanghai, including 68 Communist party member and revolutionary volunteers. Chen Guanning’s parents, Chen Erjin and Wang Manxia, could have enjoyed a good life, but they resolutely joined the Communist Party of China (CPC) and risked their lives to lurk in the Kuomintang for more than ten years.

"Before the start of the Shanghai campaign, parents sent people to Danyang to report the uprising action plan. Unfortunately, the action plan was discovered by Kuomintang agents. On May 9, my parents were arrested, along with me, who was only 11 months old. " With the rescue of the Shanghai Party organization, the Kuomintang authorities were forced to release Chen Guanning. On May 19th, Chen Erjin and Wang Manxia went to the execution ground in Song Park (now Zhabei Park), when Wang Manxia was pregnant. Later, the Central People’s Government ratified Chen Erjin and Wang Manxia as revolutionary martyrs.

　　With the country’s emphasis on the well-being of people’s livelihood, the national subsidy policy in 2024 (referred to as "state subsidy") has once again become the focus of attention of consumers. This policy aims to reduce the economic burden of consumers when buying household appliances, mobile phones and other commodities through financial subsidies. So, how to receive state compensation? On which platform can the national supplement be received? The following is a detailed interpretation.

　　First, the conditions and scope of receiving state subsidies

　　First of all, it is necessary to clarify the scope and conditions of application of state compensation. In 2024, the state subsidy policy is mainly aimed at consumers who buy first-class energy efficiency/water efficiency and second-class energy efficiency/water efficiency products. The subsidy intensity is 20% and 15% respectively, and the maximum subsidy amount does not exceed 2,000 yuan.

　　There are a wide range of commodities participating in subsidies, including but not limited to large household appliances such as household appliances and mobile phones and 3C digital products. At present, the government’s household appliance subsidy policy has covered many areas including Zhejiang, Sichuan, Shandong, Jiangsu, Guizhou, Guangzhou and Shanghai.

　　Related reading: 2024 government home appliance subsidy projector inventory! Zhejiang/Guangdong/Fujian/Sichuan and many other places can get it.

　　Second, the platform and steps for receiving state subsidies

　　The collection platforms of state subsidies are mainly divided into life apps in JD.COM, China Unionpay Quick Pass, Tik Tok and China Construction Bank, as well as people’s livelihood apps belonging to various regions (such as "One Code Connect" in Guizhou). The collection steps of different platforms are slightly different, but the general process is similar. Detailed tutorials mainly focus on JD.COM and Tik Tok:

　　1. JD.COM Platform

　　JD.COM platform is one of the main channels for receiving state subsidies, and the specific steps are as follows:

　　Step one:Search for "State Subsidy 2024" on the homepage of JD.COM APP. If the subsidy has been opened in the region, there will be a quick access entrance. For example, if I want to buy a projector, I will directly search for the subsidy of "projector", and I will also jump to the national subsidy page. We can see that many provinces have participated in the subsidy at present.

　　Step two:Click on the collection entrance to enter the subsidy collection page. Select the province where you are located and check the categories of subsidies you can receive.

　　Step 3:Click "Receive Qualification" to complete the qualification collection; After receiving the voucher, it will be automatically deposited into JD.COM account. When purchasing goods that meet the subsidy conditions, you can enjoy the discount by choosing to pay with subsidy vouchers.

　　2. Tik Tok Platform

　　The specific steps are as follows:

　　Step one:Open Tik Tok APP and search the flagship store of the product you want to buy in the search box. For example, search for "official flagship store of Dangbei" and enter the store page, and you can see that some products are marked with the logo of [20% reduction for state subsidies] in the list of products for sale.

　　Step two:Select the goods that meet your needs from the list of goods and enter the payment page. Take the new "Dangbei F7 Pro" projector as an example, select the goods with the logo of [20% reduction for state subsidies], and after entering the payment page, you will see the prompt of "20% reduction for government subsidies at the maximum" in the "total concessions" section, and you need to complete real-name authentication at this time;

　　Step 3:After the real-name authentication is successful, click Buy Now, and the receiving address can be anywhere in the country (except Hong Kong, Macao and Taiwan), and you can enjoy the subsidy after payment. The original price of 7,999 yuan for the Dangbei F7 Pro projector was reduced by 1,115.85 yuan (15%), plus the 400 yuan coupon for the platform and the 160 yuan coupon for the store, only 6,323.15 yuan was needed!

　　3. China Unionpay Quick Pass Platform

　　The China Unionpay Quick Pass platform also supports the collection of state subsidies, but it should be noted that some areas may need to jump to China Unionpay Quick Pass to qualify first. The specific steps are as follows:

　　Step one:After obtaining the qualification in JD.COM or the designated platform, if you are prompted to jump to China Unionpay Quick Pass, download and register the China Unionpay Quick Pass APP.

　　Step two:In China Unionpay Quick Pass APP, find the "Home Appliances Subsidy" or "State Subsidy" area and enter the collection page.

　　Step 3:Select the region and subsidy category, and click "Eligibility".

　　Step 4:When purchasing goods, you can enjoy preferential subsidies by choosing China Unionpay Quick Pass as the payment method.

　　4. CCB Life APP Platform

　　CCB Life APP is also one of the platforms for receiving state subsidies, but attention should be paid to the list of enterprises and stores participating in the activities. The specific steps are as follows:

　　Step one:Download and register CCB Life APP.

　　Step two:Find the "national subsidy" or "home APPliance subsidy" activity entrance in the app.

　　Step 3:Select the region and subsidy category, and click "Eligibility".

　　Step 4:Go to the designated store to buy goods, use CCB Life APP to pay, and you can enjoy the subsidy discount.

　　Third, matters needing attention

　　1. Real name use:National supplement qualification can only be obtained once in each category, used once, and must be used in real name. Different regions and platforms cannot be collected and used repeatedly.

　　2. Timely use:After receiving the qualification, it should be used in time to avoid expiration. The validity period of subsidy vouchers in different regions may be different, and they need to be collected and used according to the rules of the region.

　　3. Platform selection:Before receiving the qualification, consumers should first check the platform selected by enterprises or stores in the list of participating enterprises and stores published by official website.

　　4. Payment method:Subsidy vouchers in some regions need to be paid on designated platforms, such as China Unionpay Quick Pass. When purchasing, make sure to choose the right payment method to enjoy the subsidy.

　　Four, the new area to receive the process:

　　The national subsidy policy in 2024 provided tangible benefits for consumers. By understanding and following the above collection steps and precautions, you can easily collect and use the national supplementary coupons and enjoy the benefits brought by shopping. At the same time, it is also recommended to pay attention to the latest news and activity rules released by the government to ensure that no preferential opportunities are missed. Take the Danube projector as an example,Nowadays, there is still the last month left in the 24-year subsidy, and the Double Twelfth and New Year Festival are just around the corner.

Omicron is the most serious mutation so far. There are more than 30 mutations in spike protein, 15 of which occur in receptor binding domain (RBD). This COVID-19 mutant poses new challenges to scientific research and epidemic prevention decision-making. A recent study published in Nature, a top academic journal, pointed out that a key question for China is whether the inactivated vaccine that has been inoculated on a large scale also has a severe protective effect on Omicron mutant.　

On January 28th, Nature published a study jointly completed by researchers from the Institute of Biophysics of Chinese Academy of Sciences, the Institute of Medical Experimental Animals of China Academy of Medical Sciences, the Institute of Microbiology and Epidemiology of the Academy of Military Medicine of the Academy of Military Sciences, China Institute of Food and Drug Control (NIFDC), Beijing Kexing Biological Products Co., Ltd., etc. The research team systematically analyzed the titer of neutralizing antibodies in the serum of volunteers vaccinated with CoronaVac and the antibody spectrum of memory B lymphocytes.　

The research was led by researcher Wang Xiangxi from Institute of Biophysics of Chinese Academy of Sciences and Key Laboratory of Infection and Immunity of Chinese Academy of Sciences. Other correspondents included researcher Qin Chengfeng from Institute of Microbiology and Epidemiology of Academy of Military Medicine of Chinese Academy of Military Sciences, Wang Youchun, chief expert of vaccine testing of China Food and Drug Testing Institute, and Qin Chuan, director of Institute of Medical Experimental Animals of China Academy of Medical Sciences.　

It is mentioned in the paper that although the currently approved COVID-19 vaccine continues to be effective against serious diseases and deaths caused by Delta mutants, the third dose of vaccine or even the development of new vaccine is needed due to the decreased immunity and large-scale breakthrough infection caused by virus mutation.

Previously, on December 8, 2021, Pfizer announced that a preliminary laboratory study showed that three doses of Pfizer /Biontech mRNA COVID-19 vaccine BNT162b2 could neutralize the mutant strain in Omicron, Covid-19. Compared with two doses of vaccine, inoculation of three doses of the vaccine increased the titer of neutralizing antibody by 25 times.

The research team believes that these preliminary data about Omicron neutralization sensitivity need further independent verification, and the clinical effects of natural immunity and vaccine-induced immunity in preventing infection and serious diseases also need urgent investigation. As far as China is concerned, inactivated vaccine has been inoculated on a large scale up to now. Does this also have a serious protective effect on Omicron mutant? What is the necessity of three doses of vaccination?

In this study, Wang Xiangxi et al. collected the sera of 60 volunteers who had been inoculated with inactivated vaccine twice (in the procedure of October and January) and 60 volunteers who had been inoculated with inactivated vaccine three times (in the procedure of October, January and July), and evaluated their neutralization titer against the original strain and Omicron mutant by COVID-19 live virus neutralization test. None of these volunteers were infected with Covid-19 before the study, and blood samples collected four weeks after the last vaccination were used in the study.

Evolution and neutralization characteristics of Omicron mutant.

The data showed that the geometric mean median maximum neutralization titer (GMT NT50) of the volunteers inoculated with three doses of inactivated COVID-19 vaccine against wild-type (WT) virus, Delta and Omicron mutant were 253.9, 77.8 and 15.4, respectively. Compared with the wild-type virus, the semi-maximum neutralization titer of Delta and Omicron decreased by 3.3 times and 16.5 times respectively. Three of the 60 volunteers had an NT50 titer of less than 8 for Omicron. In other words, the seroconversion rate of neutralizing antibody against Omicron in volunteers vaccinated with three doses of inactivated COVID-19 vaccine was 95%.

However, they mentioned in their research that what deserves more attention at present is the effectiveness of the two-dose vaccination program for Omicron infection. In the two-dose inoculation group, compared with the wild-type (WT) virus, the NT50 titer of Delta was 6.6, which was 5.1 times lower. Notably, none of the 60 volunteers had a serum sample with an NT50 titer greater than 8 for Omicron.

These results showed that the neutralizing ability of COVID-19 mutant strain was poor after inoculation with two doses of inactivated vaccine, and the neutralizing antibody titer in vivo could be improved by inoculation with the third dose of inactivated vaccine. However, the titer of neutralizing antibody against Omicron mutant was still low. The research team believes that their data is consistent with previous observations, that is, three doses of inactivated vaccine inoculation can enhance the neutralization breadth of SARS-CoV-2 mutant.

Strengthen the characteristics of broad-spectrum neutralizing antibodies in needle volunteers.

It is worth noting that after the existing vaccination, the level of neutralizing antibody in serum is not enough to fully curb breakthrough infection, so why can it effectively provide severe protection?

The research team isolated immunoglobulin (IgG+) memory B cells from peripheral blood mononuclear cells (PBMCs) of four three-dose vaccinators, obtained the sequences of antibody heavy chain and light chain variable regions and expressed 323 strains of antibodies in vitro. They found that 163 antibodies recognized virus RBD, 100 antibodies recognized NTD and 51 antibodies recognized S2. The test results also showed that almost all antibodies that bind to RBD can bind to wild-type strains, among which 127 antibodies have neutralizing activity against wild-type strains of real and pseudoviruses, and they chose these antibodies for further study.

Among these 127 strains of antibodies, more than 93% showed extensive binding activity to most of the mutants of concern and interest. It is worth noting that 85% of these antibodies cross-react with Omicron RBD.

In contrast, about 80% of NTD-binding antibodies lost their cross-reaction with Omicron. In addition, due to the great diversity of NTD, the cross-reaction of NTD antibody to the other four variants of concern is relatively poor.

Their research also found that among the antibodies binding to RBD region, 31 strains can effectively neutralize wild-type pseudoviruses and true viruses and all concerned variants, and the semi-inhibitory concentration IC50 is between 0.002 and 0.800μg/ml. Among them, 30 strains of antibodies can directly block the binding between RBD and ACE2.

Among the 31 strains of broad-spectrum potent antibodies isolated in this study, 13 strains have IC50 less than 0.02ug/ml to Omicron, which is 10-40 times as high as that of VIR-7831 from GSK/Vir and DXP-604 which is still in the clinical trial stage in China.

The structural basis of extensive and effective neutralization of representative antibodies.

The research team also selected four antibodies for further structural biological analysis. Among them, XGV347 (class II antibody) and XGV289 (class IV antibody) have strong neutralizing activity against all concerned mutants, including Omicron.

They also identified the interaction between these antibodies and Omicron spike protein, and identified a mutation G446S of spike protein, which is more resistant to a class of antibodies that bind to the receptor binding domain and is a key escape site.

Structural comparison shows that XGv347 is similar to a neutralizing antibody (A23-58.1) which is effective against several Covid-19 mutants, and is similar to the epitope (antibody binding site) targeted by another neutralizing antibody (S2K146). It is worth noting that S2K146 is effective against other strains of coronavirus B (i.e., subgenus sarbecovirus, a group of virus strains to which Covid-19 belongs).

Further experiments in this study also show that the representative broad-spectrum neutralizing antibody therapy has a high protective effect on the infection of beta mutant and Omicron mutant in mice.

Protective effect of neutralizing antibody therapy on infection of beta mutant and Omicron mutant in mice.

The research team believes that this study proves that the three-dose vaccination program is reasonable under the current pandemic. At the same time, antibodies that identify and identify epitopes in the same region can be classified, and different types of antibodies can form cocktail therapy, which can be used to prevent and treat current epidemic strains and new strains that may appear in the future, or help to develop a general vaccine strategy for branch B of coronavirus B.

　　On September 27th, the technical team jointly formed by China National Computer Virus Emergency Response Center and 360 Company released the second investigation report on the cyber attack of China Northwestern Polytechnical University by the National Security Agency (NSA). The report disclosed in detail a series of cyber attacks and infiltration behaviors, such as the targeted access operation (TAO) under the NSA attacking, controlling the network of Northwestern Polytechnical University, infiltrating the infrastructure of China, inquiring the information of sensitive identity personnel in China and sending it back to the NSA headquarters.

　　For a long time, the United States has frequently hyped the so-called "China Hacking Theory", but it has continued to carry out large-scale, organized and indiscriminate cyber theft, monitoring and attack around the world, weaving a "monitoring network" covering both inside and outside the United States.

　　A "monitoring network" that snares the privacy of American citizens

　　After the "September 11th Incident" in 2001, the U.S. government, eager to take revenge on terrorist organizations, gave NSA unprecedented authority, giving it the power to monitor almost everything, including civil communications and the Internet. Since then, the NSA has secretly carried out a large number of monitoring plans and projects, unscrupulously spying on citizens’ personal privacy, and the "monitoring network" in the United States has begun to accelerate its weaving and penetrate into all aspects of citizens’ lives.

　　In 2013, Edward Snowden, a former outsourcing employee of the Central Intelligence Agency (CIA), exposed the NSA’s "Prism Project" to the media. The incident shocked the world. This is the first time that the monitoring plan of the United States has been exposed to the world on a large scale, including a large number of projects to monitor the communications and networks of American citizens.

"Prism Project" Project Process (Photo/Guardian)

　　According to Snowden’s disclosure, in 2013, the "black budget" of American spy agencies was nearly $53 billion. With the financial support, NSA wantonly violated the privacy rights of American citizens, at least hundreds of times a year.

　　The US government secretly instructed the telecommunications company Verizon to hand over all the daily call data of users to NSA. At the same time, NSA also directly invaded the servers of nine Internet companies, including Facebook, Google, Microsoft and Yahoo, and tracked and collected online communication data of users.

　　Terrible is that "Project Prism" is just the tip of the iceberg, and there are countless monitoring plans and projects such as "Stellar Wind" and "Irritant Horn", which together form an invisible net, including every move of American citizens.

　　　America’s "monitoring network" covers the whole world

　　In addition to sparing no effort to monitor and monitor its own citizens, the United States has also engaged in cyber attacks, eavesdropping and stealing secrets around the world, turning a blind eye to international law and the basic norms of international relations.

　　The NSA code-named "Stateroom" project installed monitoring equipment in nearly 100 embassies and consulates around the world, and also monitored the phone calls of 35 world leaders including the UN Secretary-General, the German Chancellor and the Japanese Prime Minister, which made the then German Chancellor Merkel, who always regarded the United States as an ally, furious.

　　In addition, in 2009, the United States created the "MYSTIC" to collect telephone metadata of Bahamas, Mexico, Kenya, Philippines and other countries under the guise of providing legitimate business services to foreign governments.

　　At the same time, monitoring submarine optical cables, selling "encryption devices" and stealing secrets through cyber attacks are also the usual means of American espionage. For example, the United States monitored submarine optical cables through the Upstream program, and collected 13.25 million Internet communications in the first half of 2011 alone. The CIA also secretly manipulated the Swiss "Clepto AG" encryption equipment company to obtain encrypted communication information in more than 120 countries.

　　Although surveillance projects have been exposed so frequently, the United States has never restrained its global surveillance behavior. In 2020, both the Irish Data Protection Committee and the French National Committee for Information and Freedom publicly accused American Internet companies of leaking user data; In 2021, Danish media also exposed that NSA used Internet facilities in Denmark to monitor senior officials and entrepreneurs in European countries.

　　　A huge arsenal of cyber attacks

　　In August this year, lawyers and journalists around Assange, the founder of Wikileaks, accused the CIA of illegally collecting information on their electronic devices and recording their correspondence with Assange, infringing on privacy. Since Wikileaks exposed the CIA’s related plans on a large scale in 2017, the United States has been targeting various charges against Assange Luo Zhi. Why is the CIA targeting Assange so much? Are you afraid that Wikileaks will expose their crimes again?

　　In 2017, Wikileaks exposed the information of the CIA’s cyber attack arsenal codenamed "Vault 7" (vault 7), and disclosed and interpreted 19 batches of cyber attack weapons, totaling more than 8,700 sensitive documents.

Part of "Vault 7" revealed by Wikileaks

　　According to the data, a large number of CIA cyber weapons can be used to attack almost any platform, from Windows and Linux systems to Android, Apple MacOS and iOS devices, and even Samsung Smart TV, so as to carry out data theft and continuous monitoring and monitoring.

　　"Vault 7" shows the overall capability of CIA cyber attacks and the richness of CIA cyber armory, which makes countries around the world have a clearer understanding of the hacking strength of the United States.

　　This year, China National Computer Virus Emergency Response Center and other information security agencies, through long-term follow-up analysis and evidence collection from several injured units, confirmed that the NSA has been carrying out extremely covert cyber attacks on China for a long time, and successively discovered several major cyber attack weapons in the United States-"Operation telescreen" (Bvp47), QUANTUM attack system and "Hive".

Application Scenario of American Quantum Attack System Project (Figure /EFF)

　　The U.S. Department of Defense’s FY 2022 Budget increased the Department of Defense’s network-related budget to $10.4 billion, including $4.3 billion in cyber warfare to support activities such as network intelligence gathering, defensive cyberspace action (DCEO) and offensive cyberspace action (OCEO).

　　In fact, the United States is abusing its leading edge in Internet and communication technology, eavesdropping and stealing secrets with the help of technological hegemony, trying to weave an impenetrable "monitoring network" around the world, which is a veritable "matrix empire, eavesdropping empire and stealing empire".

　　When Zhejiang civil servants carry out general official activities within the provincial scope, the reception unit will assist in arranging code scanning meals at designated places; Yiling District, Yichang City, Hubei Province, explores the establishment of a "digital canteen" to realize one code for all canteens in the district … Recently, many places have tried out the reform of official meals, ensuring uniform standards and traceability of official meals by scanning codes, solving the problem of illegal eating and drinking from the system, and further establishing a new atmosphere.

　　Since the 18th National Congress of the Communist Party of China, the CPC Central Committee has made great efforts to strictly rectify the problem of illegal eating and drinking, and put an end to "waste on the tip of the tongue" and achieved remarkable results. Strictly and carefully implement the spirit of the eight central regulations, issue and implement the Regulations of the Party and Government Organs on Strictly Saving and Opposing Waste and the Regulations on the Administration of Domestic Official Reception of Party and Government Organs. By setting standards and drawing a "red line", the unhealthy trend of official eating and drinking has been stopped to a great extent, and blatant illegal eating and drinking has been effectively curbed.

　　But at the same time, some invisible variation of illegal eating and drinking began to emerge. For example, eating official letters, eating bosses, charging according to the standard but exceeding the standard reception, and so on. These illegal eating and drinking from bright to dark are more difficult to find and have a worse impact. Official scanning code dining can solve the problem of extravagance and waste and over-standard reception by strictly stipulating the dining place and dining standard, and the digital empowerment can be traced; At the same time, self-scanning and self-reimbursement have reduced a lot of work for party member cadres to apply for bills and submit accounts for verification, and further released the energy of everyone to start a business.

　　On the one hand, it is important to control illegal eating and drinking and improve the system, and the consciousness of party member cadres is also very important. You know, whether it’s subordinates or clients, illegal reception is essentially aimed at the power in the hands of party member cadres. Leading cadres should lead by example, say "no" to illegal eating and drinking, and don’t take any chances for a bite. As a result, they will ruin their future, spoil their style of work and damage the image of the party and the government.

　　Tianjin North Network News:When we were young, we all played a video game "Super Mario". Mario, the protagonist of the game, had to cross many hurdles along the way and finally reached the peak of his life. The more obstacles in the game, the more fun the game participants can have. However, in reality, obstacles on the road will only bring inconvenience and safety risks to passers-by. Especially when obstacles are "attached" to the blind road, it is a disaster for visually impaired people.

　　The blind road is not dispensable, it is the standard of a city civilization, reflecting whether the city is friendly to visually impaired groups. Perhaps this convex road is not used by many people, but it is "just needed" for everyone who needs to use the blind road.

　　This wonderful blind road is very unfriendly.

　　Summer evening, Haihe Square, Tianjin Railway Station. People sat on the shore and watched the night view of Haihe River, welcoming the people who were sent, and it was bustling. This is the place where many foreign guests look at and examine Tianjin at first sight, and it is also the most beautiful memory left in the minds of many parting people.

　　Walking along Haihe East Road to Chifeng Bridge, walking on the sidewalk, the scenery along the line is excellent, but it seems that there is a little less affinity. Where is the affinity? The reporter sat there and studied it carefully — — It’s a blind road. There’s something wrong with the blind road.

　　Walking out of the fence in the Tianjin station area, the blind road suddenly narrowed. Previously, it was more than enough to put your feet on the blind road, while the blind road on Haihe East Road only left the width of one foot. Imagine a visually impaired person walking on a blind road. He needs to keep his feet steady, leave a certain position for the blind stick, and use the blind stick to detect the road ahead, so as to judge his walking direction. And the blind road in front of us, which can only accommodate one foot, is it necessary for the visually impaired to take a "catwalk" on the road?

　　Careful observation shows that the sidewalk on Haihe East Road is higher than the non-motor vehicle lane, and the road width is spacious, so the blind road should be built in the safest position on the sidewalk. However, the blind road on Haihe East Road is located in the nearest place to the non-motor vehicle lane. The road less than 50 cm away is just bicycles and electric cars that come and go in a hurry, which means that the visually impaired will fall down the steps if they are not careful, and the risks of spraining their ankles and being hit by other vehicles will increase sharply.

　　Look at the obstacles on this blind road, which are varied and involve many departments and units. The manhole cover of the power sector straddles the blind road, and the street lamp pole "happens" to stand in the center of the blind road; Walking around the fire hydrant of the fire department; The street sketch of the garden department is very exquisite. One person’s height is more than one person’s face, right in the middle of the tree, and there is a fire hydrant hidden. According to the National Barrier-free Facilities Standard, blind roads should be laid continuously, and obstacles such as trees, telephone poles, guy wires, tree holes and manhole covers should be avoided, and other facilities should not occupy blind roads.

　　If these obstacles can be predicted in advance through the blind stick, then the next "obstacle wall" can really make the visually impaired people unable to find the way forward. Ramps were built from the sidewalk on the Haihe River to the pro-platform, and decorations like piers were set up at the entrance of each ramp. Here, the decorations just blocked the blind road, and there was no guidance on the following road, so the blind road became a "broken road".

　　People can see treading on thin ice along the way, but these obstacles are concentrated within a short 200 meters. This 200-meter blind road is like a game level. Even if a healthy person walks with his eyes open, it is inevitable that there will be no bumps.

　　The reporter chatted with the public about this blind road. Some people say: "This kind of blind road is redundant. If visually impaired people really walk on it, they will be lucky if they don’t get bruised." Some people also said, "Move the blind road inward and transform the steps into gentle slopes, so that fewer obstacles will make it safer." Others said: "This blind road is like dealing with an errand. Is there a blind road? Yes! Anyway, I built … …”

　　The blind road is a "static eye"

　　The transportation of visually impaired people is a livelihood issue that cannot be ignored, which has been written into the Measures for the Construction and Management of Barrier-free Facilities in Tianjin. It stands to reason that all the streets and alleys in the city should be equipped with corresponding facilities to help the blind to travel safely.

　　What does the blind road mean to the visually impaired? A year ago, our reporter went to Tianjin visually impaired school to find out. The teacher of the school told the reporter that children studying in visually impaired schools will set up directional walking classes in the fifth grade. They must first learn to use the sense of feet and the conduction perception of blind brick on campus to judge the direction of the road. Strip bricks mean that you can go straight, and regular polka-dot bricks mean stopping and turning. Different tactile sensations can let the blind know what changes will occur in the spatial environment of the route ahead. Children in visually impaired schools told reporters through personal experience that they need to keep composing pictures in their minds when they walk. When they walk through this road, they must rely on the feeling under their feet and the hearing of their ears to build a three-dimensional picture. The blind stick in their hands is like a detector, and they can always check the road conditions 1 meter away. When there is an obstacle at a certain point in this picture, it is necessary to bypass it, and this point will stay in this three-dimensional picture for a long time. When you walk next time, you will be particularly careful and even dare not pass here again. It is not until several attempts have been made to find that the obstacle has been removed that this obstacle point may disappear from memory.

　　When interviewed in a school for the visually impaired, children always show bruises on their knees and calves when they lift their trousers. Often, this bruise has not subsided, and the next collision will come again. The children told reporters that it was hit on the way home. On campus, teachers take care of them in every way, and all facilities should be guaranteed not to harm blind children; But after stepping out of the campus and entering the society, you will find that some facilities on the road are not friendly to them. This kind of injury stays on their bodies, but it hurts in the hearts of healthy people. More seriously, every collision is a psychological blow to the visually impaired. The greater the blow, the more afraid they will be when they go out — — The obstacles on the road eventually turned into obstacles hidden in their hearts.

　　In addition to the obstacles left over during construction, there are also many obstacles erected artificially. For example, it is not uncommon for cars to park in blind roads. Nowadays, it is common for bike-sharing to occupy blind roads, and the litter left by pets on blind roads also makes it difficult for blind people to travel.

　　In addition, the color of blind floor tiles is different from that of ordinary floor tiles. Its eye-catching color was originally designed to make it easier for people with slight visual impairment to distinguish, and at the same time, it was also designed to make healthy people look in their eyes and avoid at any time, leaving a safe road for blind people. Its function is to remind and warn, not to become an ornament. To put it more directly, the blind road is not for the healthy people to "watch". The straight and barrier-free blind road is the "just need" of the visually impaired. Even if it looks monotonous, it is a great sustenance for the blind people to travel safely.

　　Healthy people should at least put themselves in other’s shoes. If empathy can’t be realized, then simply blindfold yourself, experience it for yourself, and actually take a trip to see if this road can help the visually impaired.

　　Barrier-free public facilities embody civilization.

　　At the beginning of this century, many enterprises and institutions called on cadres and workers to read a book, Details Decide Success or Failure. From then on, the sentence of the title of the book has been deeply implanted in people’s minds, always saying: success is also detailed, and failure is also detailed. But is "details determine success or failure" really implemented in action?

　　Going back to this blind road, watching the high-rise buildings in this city row upon row and the rapid development of urban construction is a kind of momentum and enjoyment. But look at this blind road at the foot, which embodies humanistic care and social justice. Its "details" have been forgotten, at least here the blind road has become a "blind area". Although visually impaired people are a "minority" group in society, their rights and interests can not be ignored, and the relevant government departments should attach great importance to them.

　　And how many blind roads are there in Jincheng like Haihe East Road? Should we take this as a guide, re-examine the barrier-free facilities in this city, and make the repairs and changes. From the perspective of planning, designers should make efforts to make blind roads more scientific and reasonable, reduce detours as much as possible, provide straight walking routes for the blind as much as possible, and combine the overall planning of the city with blind roads efficiently and conveniently, so as to make disabled people, including the blind, happy and convenient to travel in this city.

　　This is the second time that the "Viewpoint" edition of this newspaper has carried out an in-depth report on the blind road problem. Fortunately, after the publication of the report in 2017, some street crossing lights in our city were equipped with voice control devices, so that the blind can safely cross the street with the rhythm of sound. However, the popularity of such voice-activated indicator lights is still not high, and the voice of guidance is not loud enough. This time, we have an in-depth discussion on the blind road, hoping to make the details of the city more perfect. After all, the municipal facilities that show care for the disabled also show the "soft power" of a city.

　　Barrier-free public facilities such as blind roads reflect the civilization level of a city and the moral level of the public. Caring for the blind road is the responsibility of the whole society, which certainly needs to be vigorously publicized to improve the awareness and moral level of caring for the disabled; But the most important thing is management. From the design, construction and maintenance of barrier-free facilities to daily supervision, it is essential to implement it meticulously with the idea of taking the disabled as the center. Ensuring the smoothness of the blind road will make more and more visually impaired people have the courage and confidence to go out of their homes and travel with us in this loving city.
