At the 2021 Munich Motor Show, the new Multivan was officially unveiled. The new car no longer shares the Transporter platform with the freight version of Kailuwei, but is based on audi ag’s MQB platform, which will have a more suitable driving experience for passenger cars. In terms of power, there will be 1.5T and 2.0T gasoline power, diesel power will be added next year, and the first plug-in hybrid version will be available.

　　The new Maitewei Multivan comes standard with LED headlights, and can be upgraded to interactive IQ.LIGHT matrix LED headlights. The full-beam design brings better intelligent corner lighting effect, while avoiding glare hazard to the driver of the other vehicle; The IQ.LIGHT system also runs through an LED horizontal light bar in the front grille as another element of daytime running lights, which is also one of the iconic designs of the new generation of Volkswagen family.

　　The new Maitewei Multivan continues the classic square box shape, and the double A-pillar design is the biggest difference from previous models, which can effectively reduce the blind spot of vision; Its body size is 4973/1941/1903mm and its wheelbase is 3124 mm. A longer version with a length of 5173mm is also available.

　　Founder’s tail is a typical MPV shape, and the style of horizontal split taillights is somewhat similar to the current Touran L.

　　The interior adopts a brand-new design, and uses a wood decorative board and a piano paint panel to enhance the sense of grade, which distinguishes it from the style of the current tool car. Following the concept of popular digitalization, the new Maitewei Multivan is also equipped with a 10.25-inch LCD instrument and a 10-inch central control panel, and uses an electronic lever design similar to that used on Golf 8.

　　The new Maitewei Multivan has also been upgraded with IQ.DRIVE Travel Assist intelligent driving assistance system, which realizes semi-automatic driving by combining predictive adaptive cruise control and lane assist system, making long-distance travel safer and easier. At the same time, it is also equipped with panoramic image function.

　　In terms of power, the new Maitewei Multivan will be equipped with 1.5T and 2.0T engines, matching the 7-speed dual-clutch gearbox; A diesel engine will be provided in overseas markets next year. In addition, the new Multivan will also provide a plug-in version for the first time, which consists of a 1.4T engine and an 85kW motor, and the transmission system is a 6-speed dual-clutch gearbox.

How to see the gold content of a car company through products? Some people say that it depends on the technical content of the product, and the gold content will naturally not be low if all kinds of intelligent technologies are added.

Such a statement seems to be sophistry.

Have you noticed, from Bosch and Magna to Mobileye and Horizon … There are countless high-tech manufacturers in the world providing intelligent system solutions for vehicles. Many car companies can also support the scientific and technological system of vehicles through procurement schemes.

The gold content of a car company should be in the quality itself. To give a very simple example, the gold content of Volvo brand lies in safety; The gold content of BMW lies in manipulation; The gold content of Lexus lies in the control of details …

In fact, looking at major domestic manufacturers, there are also many brands that can make us shout "something".

Great Wall Motor, for example, takes a similar path to Volvo, and interprets the kindness of this manufacturer with excellent safety.

What does the record-breaking test result mean?

On April 6th, China Insurance Automobile Safety Index (C-IASI) released a new round of vehicle evaluation results. Among them, the tank 300 from Great Wall Motor (parameter picture) can be described as brilliant.

With the achievement of "1A3G", this car has gained the best performance of non-loaded body models in recent years.

In fact, as a hard-core off-road vehicle equipped with a girder structure, it is not difficult to get good results in a 25% offset collision or side collision. After all, it is supported by a girder with a hard bottom.

The difficulty of non-load-bearing body is that the strength of the roof is difficult to optimize.

In terms of structure, the chassis and cage structure of hard-core off-road vehicle belong to two unrelated parts, and the non-load-bearing body has low requirements on the strength of the body structure. This also means that most hard-core off-road vehicles can’t disperse the pressure through the chassis like a load-bearing body when the roof is stressed. The facts also show that the strength of the roof is also the "pain point" of many off-road vehicles.

In the IIHS crash test in the United States, Toyota 4RUNNER, which is also equipped with girders, but has no in-car roll cage, only achieved "poor" results in the evaluation project of body structure due to insufficient roof strength.

However, herdsman JL, which is equipped with a girder and an in-car roll cage, can’t be equipped with an air curtain at the side of the head due to the relationship between the detachable door and the roll cage, although the body structure remains good in the collision, and the overall protection effect is also relatively general.

What about the tank 300?

In the C-IASI test, the roof of this car can bear the peak load pressure of 151,877 N at most, and the score is "G(Good)". At the same time, with a series of restraint and protection equipment such as seat belts and side air curtains, this car has got a very high score in occupant protection, and even broke the test record of China Insurance Research Institute.

It can be seen that the overall safety factor of the tank 300 is indeed not low. This refreshes the industry standard crash test results, and also adds a safe "background color" to the off-road vehicle market.

The test is as fierce as a tiger. What about actual combat?

There are many models that can always get high scores in major crash tests; However, in actual traffic accidents, the protective ability is not so satisfactory.

In fact, speaking of this, we can come up with the statement that "the environment of collision test is equivalent to a laboratory, but the actual road traffic accidents are strange and varied, and there are various tricky angles". But if we think about it carefully: what is the significance and purpose of crash testing? Isn’t it just to test the safety of vehicles and urge car companies to build safer models? Therefore, the collision test can cheat, but the real security strength can’t be mixed with any water.

If you look at the achievements of Great Wall Motor, you may be more confident.

At the end of 2020, a Wei brand VV6 carrying five people flew out of the guardrail of Guang ‘ao Expressway, falling 20 meters freely. The vehicle was unrecognizable, but the driver and passengers in the car were not serious.

On the bilibili, we can also find many videos of the tank 300 tumbling because of the driver’s reckless operation. Similarly, the tank 300 can still keep the main structure intact, allowing the driver to get out of the vehicle safely, whether it is overturned on a slope or playing with sand.

In fact, behind these accident cases, it not only proves the excellent crash test results of tank 300. At the same time, it also reflects the "conscience" of Great Wall Motor.

If we go deep into the protective ability of this car, we can probably summarize it as "reasonable design structure" and "solid material level".

Although the tank 300 based on the tank platform adopts the non-loaded body design, engineers still make a lot of optimization.

For example, in the passenger compartment structure above the chassis, the stable annular force transmission channel design is still adopted. This design concept is similar to many load-bearing body structures. In the event of a collision, the collision force can still be quickly dispersed, so as to avoid a single point being overstressed and invading the passenger compartment space. There is no doubt that this design used in non-loaded body will increase the cost and weight of the car to a certain extent, but it also avoids the inherent problems brought by non-loaded body.

Of course, it is still not enough to rely on reasonable structural design. Above the structure, what is more important is the level of materials used, which also tests whether a car company has enough conscience.

Needless to say, the trapezoidal girder chassis of the tank 300. In the test video released by C-IASI, we can see that when the tank 300 collides with 25% overlapping offset, the vehicle quickly deviates from the direction of collision energy through the design of the guiding structure, thus avoiding the problem of vehicle rolling.

At the same time, thanks to the extensive application of 1500Mpa ultra-high strength steel in the main load-bearing structure, the tank 300 has also withstood the roof pressure more than 7 times its own weight. This level has surpassed the performance of Mercedes-Benz GLE and Tesla Model Y, and is the top level in the current C-IASI test.

Practical-oriented design is a good design.

Why is the heat of tank 300 so high? In fact, in addition to off-road performance and luxurious interior, more importantly, the tank 300 meets the basic needs of many off-road enthusiasts from the perspective of user thinking. And such a basic demand is that it can bring a sense of security, and it is solid and reliable.

Let’s focus on the collision test of tank 300, which not only shows strong passive protection ability. At the same time, in the performance of maintenance economy and crashworthiness, the tank 300 still won the praise of "A"; In the active safety test, the tank 300 also got the evaluation of "G".

First of all, let’s talk about the crashworthiness of vehicles. As an off-road vehicle, the tank 300 will inevitably encounter some small bumps and low-speed collisions in daily use. But thanks to the excellent crashworthiness and maintenance economy, after a small collision, the owner doesn’t even have to take out his mobile phone to call for insurance, just leave or drive to a repair shop for simple maintenance.

On the other hand, Tesla Model Y with the same excellent passive protection performance has a crashworthiness and maintenance economy index of only "P (poor)". This also means that if a Model Y collides with the tank 300 at a low speed, the occupants in both cars may have no problem. However, the Tesla Model Y made of integrated aluminum alloy structure needs to spend tens of thousands of yuan to repair, but the owner of the tank 300 can pat his ass and leave … The advantages of the tank 300 really fit the actual needs of the car.

In addition, the tank 300, like many urban SUVs, is equipped with a perfect active safety system. For example, AEB emergency braking and lane departure assistance, with the appearance of these icing on the cake functions, consumers can effectively avoid collision accidents in the process of daily use and reduce the cost of car use.

Seeing this, you may have doubts in your heart: As an off-road vehicle with thick materials, the self-weight of Tank 300 is not light, and its fuel consumption is high. How to make up for it?

In fact, among off-road vehicles of the same class, the average fuel consumption of tank 300 is about 12L/100km, which is not outrageous compared with BJ40, MU-X and other models. In addition, safety and fuel economy are in front of you, and you can’t have both. What would you choose?

Most consumers have given their own answers.

In fact, seeing that the tank 300′ s slot is only "high fuel consumption", the Great Wall engineer may be very pleased!

After all, a car is made up of thousands of parts, and everyone can complain about "fatal problems" such as unsafe structure and insufficient reliability. But the tank 300 has almost no other slots except a little higher fuel consumption. Isn’t this model a success?

tag

The excellent performance of Tank 300 in this crash test has undoubtedly reassured many car owners who are ready to buy Tank 300 and Tank 500.

More importantly, no matter the excellent results in the crash test or the stable performance in the "road actual combat", the models under the Great Wall will never let people down. The gold content of Great Wall Motor is also shown in terms of safety. Perhaps in the future, Great Wall Motor will become China’s Volvo, even to the point where shine on you is better than Blue.

　　Online games have always been a young model, but recently, Shu Qi broke the convention and joined the fray as a film queen, rarely showing off his cute appearance, and even playing the pro-people card to announce or meet fans.

　　Many post-80s young models have become spokesmen for online games. After Chrissie Chau and Elizabete were announced as spokesmen for the games earlier, Shu Qi, who is the winner of the film, also announced that she would join the battle group at the age of 34, while Miriam Yeung, Xiong Dailin and Jessica C. Will also enter one after another.

Show a rare and lovely shape

　　Earlier, Shu Qi was taken a fancy to by Zhang Baohua, the founder of Go Yeah, and was awarded the tailor-made online game, becoming the first post-film spokesperson. A new round of fierce fighting in online games is just around the corner. To this end, Shu Qi, who was busy filming, secretly took time to take photos for the endorsement game earlier, and went into battle with different styles such as sports, perspective and white collar. In order to meet the needs of the game, Shu Qi rarely showed his unique skills to fans, showing cute looks, such as blowing kisses, twisting his ears and other big photos, which were as cute as the young models born in the 1980s.

Preview will be fans.

　　Regarding the shooting work, Shu Qi said that he had the feeling of returning to childhood: "The expressions and actions are so cute and exaggerated. It seems that when I play mahjong online, I have different exaggerated expressions when I lose and win." For the first time, Shu Qi predicted that he would meet fans: "I will check the leaderboards online every day. If the response is enthusiastic, I want to meet or get together with them." Play the pro-people card.

　　In addition, Shu Qi even revealed that his childhood idol was Jacky Cheung: "I like Xueyou very much. I tried to dream of him for three consecutive nights, and he was still my boyfriend in the dream." As for the goddess in mind, Shu Qi chose Gong Li and Maggie Cheung.

Oil painting panorama

Sun Yat-sen and Deng Xiaoping.

　　International Online Special: According to the British "Daily Telegraph" reported on March 17, a recent oil painting called "Discussing the Divine Comedy with Dante" was widely circulated on the Internet. This oil painting depicts the images of 103 world-famous figures with exquisite brushwork, and many Chinese, including Sun Yat-sen and Chairman Mao, appeared in this painting.

　　Chairman Mao sat in the middle and Li Baizheng sighed.

　　This oil painting is 6 meters long and 2.6 meters high, with 103 world celebrities. The Great Wall of Wan Li in China, the Egyptian pyramids, Stonehenge in Britain and other landmarks appear in the oil painting as the background.

　　Among the 103 celebrities, Chairman Mao, the great leader of China, sat at the round table in the middle of the painting and smoked. Behind him stood Premier Zhou Enlai, who was beloved by Chinese people. Marx and Lenin are having in-depth exchanges; Genghis Khan and Napoleon are neck and neck; Former US President George W. Bush holds a telescope, and bin Laden stands behind him quietly. Tojo hideki knelt before Qin Shihuang, as if in repentance. In addition, Li Bai, a great poet of the ancient Tang Dynasty in China, leaned back in his chair and sighed, with a wine bottle and a modern typewriter in front of him.

　　Joseph Stalin, the leader of the former Soviet Union, and Leonardo da Vinci, a great Italian Renaissance painter, are talking attentively. Former Russian President and current Prime Minister Vladimir Putin sat on the floor next to boxing champion mike tyson; Margaret Thatcher, the former British Prime Minister, was staring at everything with a handbag on her back.

　　In addition to celebrities, Dolly, the cloned sheep, also appears in this painting. In addition, the crystallization of human wisdom, such as Simuwu Dafang Ding, phonograph and atomic bomb, are also displayed in the painting.

　　Netizens from all over the world speculated that the creator was Chinese.

　　Who is the author of this painting? At present, netizens are scrambling to discuss it. Analysts pointed out that the creator of this painting may have been inspired by Italian painter Raphael’s masterpiece Athens School. But in Raphael’s famous paintings, the characters are all ancient philosophers. Although the characters in this painting are all world celebrities, there is no distinction between modern and ancient times.

　　However, sharp-eyed netizens still found some clues. Most of the characters in the painting are depicted in profile, and only a few people such as Chairman Mao painted the whole picture. Therefore, it is speculated that the author of this painting may be from China. In addition, there are three Chinese in the upper right corner of this painting. They are dressed in modern clothes, but many netizens in the world don’t recognize who they are. Until recently, this secret was solved. These three people are Dai Doudou, director of China Artists Association, Li Tiezi, a famous contemporary oil painter, and Zhang Anjun. Standing next to them is the Italian poet Dante.

　　Alastair Shuke, a British artist, believes that this oil painting reflects the trend of contemporary China artists to adapt to western artistic styles and themes. But Dante leads us to see the deep "hell", but this painting leads modern people to appreciate the "celebrity paradise".

　　Chinese among 103 celebrities

PAData Insight：

This year, blockchain security incidents have occurred more than 10,000 times, and the cumulative global losses have exceeded 6 billion US dollars.

Among digital asset crimes, the United States accounts for 28%, which is the largest in the world, Europe accounts for 24% and China accounts for 18%.

This year, there have been more than 28 exchange security incidents, of which more than 7 have been stolen from exchange digital assets.

More than 100 smart contract vulnerabilities have accumulated losses of more than 10 million US dollars, of which EOS DApp attacks have exceeded 60 at most, accounting for 67%.

There were more than 7 wallet security incidents in the whole year, with losses exceeding 100 million RMB.

Digital currency, which has the largest traffic of bitcoin in the dark network this year, has a total transaction value of about $1.035 billion.

This year’s cyber blackmail attacks caused losses of up to $1.5 billion, up 20% year-on-year, and various fraud crimes are still rampant.

Security has always been a hot issue in the industry. According to Chengdu Chain Security Report, in 2019, blockchain security problems caused by blockchain digital assets showed an overall upward trend, and security incidents caused by various reasons also increased significantly. There were various crimes in digital currency, including money laundering, fraud, theft, drug trafficking and mining crimes. Due to the poor security of digital currency trading platform and the complex data structure and algorithm, the work efficiency is low, especially the irregular operation behavior, which hinders the development of digital currency.

In security incidents, the project party runs away and involves the most funds.

The United States became the hardest hit area for digital asset crimes in 2019.

According to Chengdu Lian ‘an statistics, in 2019, the United States accounted for 28% of digital asset crimes, with Europe accounting for 24%, followed by China accounting for 18%. According to statistics, from January 2019 to mid-December 2019, there were more than 10,000 hacking incidents of digital assets around the world, and there were as many as 2,000 criminal cases related to digital assets in China.

In 2019, criminal means emerged in an endless stream, ransomware and money-plate running patterns were newly turned over, criminal gangs came from a wide range, and the number of criminal cases and the total amount involved in criminal activities showed an increasing trend.

In 2019, the types of global digital asset crimes include hacking, money-raising, money laundering, and illegal transactions in secret networks, with a total loss of more than 6 billion US dollars. The amount involved in cyber crimes and secret network transactions is roughly the same, and the amount involved in the project’s road running is more than twice that of the first two, of which the loss caused by system loopholes exceeds 1 billion US dollars.

In terms of hacker attacks, assets are stolen mainly for five reasons, namely, exchange loopholes, smart contract loopholes, wallet loopholes, public chain loopholes and improper use by users.

In 2019, there were more than 28 exchange security incidents.

More than 70% of digital assets were stolen.

In 2019, there were more than 28 exchange security incidents, among which more than 70% became the theft of exchange digital assets. From January, the Cryptopia exchange was hacked twice, and the stolen ETH and ERC20 currency tokens lost more than 16 million US dollars. On November 27th, 340,000 ETH was stolen from South Korea’s Upbit exchange, with an estimated loss of more than 49 million US dollars. The rest included the escape of the exchange, information leakage of the exchange and other asset losses, with a total loss of more than $1.3 billion.

On the morning of May 8, 2019, the official of Qian ‘an issued a notice saying that "large-scale security vulnerabilities" were found in the system. Hackers used composite technologies, including phishing and viruses, and stole 7,000 bitcoins from Qian ‘an Hot Wallet at a block height of 575,012. Causing the exchange to lose $41 million.

On November 27, 2019, the UpBit security system of the Korean exchange was destroyed and 34,200 ethereal coins were stolen. Causing the exchange to lose more than 50 million US dollars.

More than 100 smart contract vulnerabilities have accumulated losses of more than 10 million US dollars.

There are more than 60 EOS DApp attacks, accounting for 67%.

In 2019, the number of DApp continued to increase. According to statistics, as of the beginning of December, the total number of DApp currently running on public chains such as ETH, EOS and Wave Field exceeded 3,000, and there were more than 100 smart contract vulnerabilities this year, most of which were hacked in EOS DApp. Up to now, the total loss of DApp was over 10 million US dollars.

There are over 60 typical attacks on EOS public chain this year, and the concentrated outbreak period is from January to April, accounting for 67% of the attacks in the whole year. The main reason is the continuous popularity of spinach applications on EOS public chain and the weak security of project contract code, which leads hackers to continuously attack the same vulnerability on multiple DApp. The main methods are transaction blocking, rollback transaction attack, fake EOS attack, random number cracking and so on.

There have been nearly 20 typical attacks on the TRON public chain this year, mainly in April, May and July, with small-scale attacks as the main method and rollback transactions as the main method.

There has been no serious DApp attack on the ETH public chain this year. First, the number of spinach quiz contracts on the ETH public chain is small, and the popularity is not enough. Second, the ETH smart contract project is relatively perfect in terms of security.

There were more than seven wallet security incidents in 2019.

June is the high incidence period of wallet security incidents.

Due to the low entry threshold and poor security, in the absence of supervision, wallet security problems have broken out repeatedly, and it is easy to break out with huge sums of money. At present, there are many hidden dangers in wallet security, including the forgery of wallet APP, the failure to detect weak password in transaction password, the failure to reinforce the core code, the failure to detect the running environment of the system, and the existence of screen capture and recording records in operation.

Since at the beginning of June this year, the wallet GateHub broke out that it had been stolen by more than 23 million XRP, and there were more than 7 wallet security incidents in the whole year, with a loss of over 100 million RMB.

On October 11th, the cryptocurrency wallet ZenGoCEO Ouriel Ohayon tweeted that Safuwallet, a web cryptocurrency wallet, had been stolen by hackers by injecting malicious code.

From August to September, the bitcoin wallet Electrum was attacked by hackers twice. According to many statistics, the phishing attack that forged Electrum upgrade tips has stolen at least 1,450 BTCs, worth 11.6 million US dollars.

There have been more than 8 public chain safety incidents.

More than half of them are 51% attacks, and small and medium-sized public chains are even more threatened.

In 2019, there were more than 8 attacks on public chains, more than half of which were 51% attacks, which reduced the frequency of attacks compared with 2018, resulting in less losses.

Among the public chain attacks, on January 5th, ETC was attacked by 51% for many times, and 80,000 ETCs were used for double flowers. On August 9, hackers launched a "dust attack" on Litecoin, and the affected addresses reached 294,582. At present, it is almost impossible for large enough public chains such as BTC and ETH to be attacked by 51%. All non-large public chains and some small public chain currencies should be careful of the threat from 51% attacks.

When dealing with 51% attacks, we should try our best to keep the computing power scattered. Overconcentrated computing power is the direct cause of 51% attacks. On the basis of Satoshi Nakamoto’s consensus, 51% attacks theoretically exist forever. We should set up a sound early warning mechanism for risk control and adopt a good defense mechanism for exchanges. In case of 51% attacks, we can increase the number of block confirmations, suspend the withdrawal of money, freeze suspicious accounts and other measures to avoid losses in time.

In 2019, the overall safety awareness of users increased.

Improper use by individual users causes asset losses.

In 2019, the overall users’ security awareness increased, and some users still suffered asset losses due to improper operation of wallet private keys and access to phishing websites.

In 2019, Bitcoin became the digital currency with the most traffic in the dark network.

The total transaction value in the whole year was about $1.035 billion.

In 2019, the dark net is still an illegal place for cyber crimes, trading by taking advantage of digital currency’s anonymity to avoid supervision. In the whole year, 1.035 billion dollars worth of bitcoin has been used for illegal activities. The largest category of bitcoin traded in the dark net is drugs, and bitcoin is also the most popular digital currency, followed by Litecoin.

There are many kinds of illegal goods sold in the dark net, mainly involving data, information, illegal software, arms, drugs, etc., and criminals choose digital currency as the trading currency, for example:

In 2019, more than $5 billion in money laundering cases were investigated.

Among them, Bitcoin is the preferred money laundering tool.

In the money laundering cases investigated in 2019, more than 5 billion US dollars were conducted through cryptocurrency, among which Bitcoin was the first choice for criminals to launder money. Digital currency has become an important tool for criminals to launder money around the world. At present, there are 100-200 gambling sites companies in the world that can use digital currency to pay for gambling. Criminals open accounts on these websites, then transfer funds into accounts, engage in some small-scale gambling, and some even do not gamble, and then withdraw money to a new address to achieve the purpose of money laundering.

In 2019, cyberblackmail attacks caused at most $1.5 billion in losses.

All kinds of fraud crimes are still rampant.

Cybercrime includes fraud, extortion, and the destruction of related blockchain service providers. Criminals take advantage of the anonymity of Bitcoin, choose Bitcoin as ransom more frequently, and conduct extortion activities through ransomware or some other illegal means.

In 2019, the cyber extortion attacks caused a loss of $500-150 million to the world, which was 20% higher than last year. The criminal activities of extorting and extorting digital currency have been continuous, even increasing. In addition, this year is still a year of rampant fraud crimes, and all kinds of online fraud incidents still account for a large proportion of online criminal activities. Typical cases are as follows:

The project party’s running involves more than 25 billion yuan.

Plustoken wallet running event involves 20 billion yuan.

In 2019, among the many events of capital plates, pyramid schemes, wallets and exchanges, the most notable event was the incident of Plustoken wallet running on June 29th. On that day, many users reported that Plustoken wallet could not be withdrawn, and the project party of Plustoken wallet was suspected of running, and the amount involved may exceed 20 billion yuan. As of the beginning of December, the blockchain project that ran this year involved more than 25 billion yuan.

The difficulty of mining increases and the income decreases.

Malicious illegal mining indirectly causes social losses.

Power consumption is the main cost of mining, and it is also the key to determine the benefits of mining. With the increasing difficulty of mining, the benefits of normal mining have become lower and lower, and many people have played the wrong idea of illegal mining. Illegal means of mining-Mining Trojans get rewards from digital currency system by completing a large number of calculations. Mining Trojans and worms will occupy a lot of CPU and GPU resources of the computer in the process of calculation, which will cause the computer to become abnormally slow, interfere with the normal system operation, and spread at a high speed, causing great impact and loss to government agencies and enterprise services.

More than 5 typical information leakage incidents in the whole year.

User’s personal data has great hidden dangers due to centralized operation mode.

In mid-2019, a total of more than five typical information leakage incidents were reported. Because many exchanges and wallets are still centralized, it is inevitable to store users’ personal data. Once attacked, hackers may obtain a large number of user data, and sell data through dark networks and other means to obtain huge profits.

Summary and suggestions

Digital currency is widely used for handling fake passports, providing pornographic services, transferring illegal assets, buying and selling drugs and underground arms, which will disrupt social order, pose a threat to the stable development of society, and will also affect the development of enterprises operating normally in the industry, which is undoubtedly extremely harmful to the whole digital currency industry, the financial industry and the whole society.

From the system architecture, related enterprises and professional blockchain security research should organize cooperation to find and fix system vulnerabilities in time to avoid serious large-scale fund theft. Managers of enterprise websites and server resources should deploy enterprise-level network security protection systems to prevent enterprise servers from being invaded and installed with mining viruses and from being infringed by blackmail viruses.

For netizens who participate in digital virtual currency trading, they should fully understand the possible risks and use security software on the computer and mobile phone to avoid falling into the phishing trap and avoiding the theft of digital virtual currency wallets.

For ordinary netizens, computer poisoning should be prevented from becoming a controlled "miner", and game plug-ins, cracking software and video website client cracking tools should be used cautiously, which are more likely to be artificially implanted with malicious programs. For virtual currency, we should guard against speculation.

0one　　Pause normalized nucleic acid screening in many places.

On July 3, Shijiazhuang, Baoding, Tangshan, Zhangjiakou, Dingzhou, Chengde and other places in Hebei successively issued notices to adjust the normalized Covid-19 nucleic acid screening work:

　 First, since July 4th, the city’s weekly normalized Covid-19 nucleic acid screening has been suspended. 　 　　

Two, since July 4th, residents to enter public places and take public transport, no longer check the negative certificate of nucleic acid or "nucleic acid has been collected certificate" within 7 days. 　 　 　 　　 　 　 　 　 　 On the same day, sanhe city, Hebei Province issued a message, demanding that commuters should be well managed, and commuters can pass by scanning the "Three Rivers Epidemic Protection Pass" when they return, and no longer require daily nucleic acid testing. Xinji city made it clear that the above adjustments will be implemented from July 5th. The grassroots doctors’ commune noted that the suspension of normalized nucleic acid screening in many cities at the same time was mainly based on the "Several Measures on Comprehensively Implementing the Ninth Edition of the Prevention and Control Plan and Scientifically and Accurately Doing a Good Job in Epidemic Prevention and Control" issued by the Health and Health Commission of Hebei Province on July 2. The document is clear:In areas where there is no epidemic, in principle, weekly preventive nucleic acid screening for all staff is not carried out. 　 　 　 　 　 　 　 　 Besides,For those who enter Hebei in areas without epidemic risk, the negative certificate of nucleic acid detection within 48 hours will no longer be checked, and the landing nucleic acid detection will no longer be implemented.Hebei Province requires that all localities and departments should implement the requirements of the Prevention and Control Plan (Ninth Edition) to the letter, immediately adjust relevant prevention and control measures as required, and resolutely prevent the phenomenon of layer upon layer overweight. If the previously issued epidemic prevention and control policies and measures are inconsistent with the Prevention and Control Plan (Ninth Edition), they shall be implemented in accordance with the Prevention and Control Plan (Ninth Edition) and this notice. 　 　　

02 Implement national nucleic acid screening requirements and issue new policies in many places. 　 　　

After the release of the ninth edition of the prevention and control plan on June 28, the state held a meeting to emphasize that all localities and departments should strictly implement the ninth edition of the prevention and control plan, resolutely control the management, resolutely implement the implementation, resolutely cancel the cancellation, and clean up inconsistent measures within a time limit. At the same time, the the State Council Joint Prevention and Control Mechanism Comprehensive Group will send a working group to supervise the local implementation. In this context, in addition to the above-mentioned Hebei and other places, the requirements for nucleic acid detection have been adjusted in many places across the country in the past week, and the adjustments are mainly divided into five categories: 　 　

　 1. Cancel all the nucleic acid tests. 　 　　

Liaoning: On July 1, the latest notice was issued, saying that each city will determine the frequency of nucleic acid testing for all employees on its own according to the actual judgment. After the outbreak, it is confirmed that there is no social infection, and the whole staff can stop nucleic acid testing. Many places in Anhui: In view of the current low risk in the whole region, the nucleic acid detection work of "conducting a full-time nucleic acid inspection every 7 days" was cancelled. 　 　　

2. The frequency of nucleic acid is adjusted to "check once every 7 days" 　 　　

Jinan City, Shandong Province: Normalized nucleic acid detection frequency was adjusted from "two inspections every seven days" to "one inspection every seven days" in Qingdao, Shandong Province: Normalized nucleic acid detection frequency was adjusted from "one inspection every four days" to "one inspection every seven days" in Ningbo and Hangzhou, Zhejiang Province: from "one inspection every three days" to "one inspection every seven days" in Wuhu, Anhui Province. 　 　　

3. The frequency of nucleic acid is adjusted to "check every 5 days" 　 　　

Wuhan: from "three days for inspection" to "five days for inspection" 　 　　

4. Extend the validity of nucleic acid detection to 72 hours. 　 　

　Pingdingshan, Puyang, Xuchang and other places in Henan Province: Extend the effective time of nucleic acid detection to 72 hours. 　 　　

5. No longer check the negative certificate of nucleic acid. 　 　　

Huizhou, Guangdong: Travellers in airports, railway stations and bus stations are no longer required to hold a negative certificate of 48-hour nucleic acid test. Dezhou, Shandong: People attending theaters no longer require a "48-hour nucleic acid test certificate". On the whole, due to the influence of national prevention and control policies, nucleic acid testing has become the first step of policy adjustment in various places. The validity period has been extended from 48 hours to 72 hours, and then extended to 7 days, even suspended or cancelled, and the national prevention and control has shown a trend of slow liberalization. 　 　　

03 Prevention and control of "willfulness" plus code? The state has requirements. 　 　 　　

Since the normalization of nucleic acid detection, problems such as unauthorized overweight have frequently appeared, which has seriously affected the normal life and travel of the people, and the state has a clear attitude.At the end of April,The meeting in the State Council emphasized that the frequency of nucleic acid detection should be determined by local authorities according to the occurrence and development of epidemic situation and the need of prevention and control, and it should not be "one size fits all". At the end of June, the State Council took the lead in setting up a special class to rectify the problem of "layer upon layer overweight" and opened a public message board on the homepage of official website, National Health Commission. 　 　 　 　 　 　 In order to ensure the simplification of epidemic prevention and control, "one size fits all" and "layers of overweight", the state requires all provinces to announce the channels for complaints and reports from the masses and accept extensive supervision from all walks of life. According to the incomplete statistics of grass-roots doctors’ commune, up to now, the following provinces (cities, districts) have announced the complaint reporting methods about the overweight problem of local epidemic prevention and control. 　 　 　 　 Although the epidemic has not been completely extinguished, compared with Covid-19, the act of wanton overweight and absurd self-protection is even worse.

On April 10th, Google launched a series of practical barrier-free functions to help people with disabilities use Android phones, including text-to-speech functions, on-demand reading, subtitles and other functions. According to XDA, today Google launched a new function in its TalkBack service: a virtual Braille keyboard, which enables visually impaired people to type on their mobile phones without additional hardware (and without listening to Talkback voice prompts).

Google said that they have worked with Braille developers and users to develop this virtual keyboard, which will be familiar to anyone who has entered Braille before.

The keyboard adopts a 6-key layout, and each key represents one of the 6 Braille dots to form any letter or symbol. For example, typing "A" requires pressing point 1, while typing "B" requires pressing points 1 and 2 at the same time. Users can also use the keyboard to delete letters and words, add lines and submit text.

IT House understands that the new Braille keyboard will be integrated into the Talkback service as part of the "Android Accessibility Kit". . This feature is applicable to all applications, supports Braille Level 1 and Level 2, and is currently only available in English. It should be noted that the Talkback gesture is not available when the Braille keyboard is turned on.
