The following is a summary of the speech:

Development and challenge of Baidu Apollo intelligent driving domain controller

In the past ten years, Baidu has accumulated rich technology and experience in the field of artificial intelligence, and now it applies these leading AI technologies to the automotive field. The product strategy of Baidu’s intelligent driving business group is laid out in three areas, which are car, road and line.

"Car" refers to the intelligence of cars. ASD, Baidu’s smart car division, is a tier1 role that provides full-stack smart car solutions for B-end car customers, including smart driving and smart cabin. At present, it has provided smart car solutions for 31 car companies, 134 models and more than 7 million cars. Baidu’s car is one of Baidu Apollo’s partners, and will be equipped with the full-stack intelligent solution of Baidu smart car, which will be listed this year.

"Road" refers to smart city traffic. At present, Baidu’s smart city transportation has provided solutions for 63 cities across the country, providing efficiency for urban transportation.

"Travel" refers to providing travel services for C-end consumers, which is known as radish running. Last year, Baidu released the sixth generation RT6, which has the ability to drive automatically on complex urban roads, and its cost reached 250,000 yuan. The mass production of RT6 will greatly accelerate the scale and commercialization of unmanned vehicles.

The above businesses complement each other. Baidu has accumulated rich technology and experience in L4 field, which can provide hot start for L2+ products. L2+ products feed back L4 products with the advantages of scale, and solve the long tail problem of L4 products’ final commercial landing.

Baidu’s smart car products include intelligent driving and intelligent cabin, including small-scale in-vehicle system and software and hardware integrated solution ARC. The intelligent driving domain controller is divided into two heterogeneous control chips, MCU and SOC. MCU deployed AUTOSAR protocol station, and developed CDD and application algorithm on this basis. The bottom layer of SOC is a system, and the top layer is the hardware poke layer and the middleware Apollo OS； developed by Baidu. Further up is the various atomic ability services of the algorithm; Further up are the various application logics of the algorithm.

Next, we will share the challenges we face in the development of intelligent driving domain controller MCU software based on AUTOSAR.

First of all, in recent years, there are many projects of Baidu’s intelligent driving domain controller, and it has already faced the situation that the same hardware platform supports multiple projects and multiple models for parallel development. A project needs to maintain independent software branches, and software changes, software optimization or repairs made in one project branch are always manually migrated to other project branches to ensure the consistency of product experience. And the coupling between software modules is very strong, and the change of one software module will often lead to the change of other modules, which will affect the whole body; In addition, it is necessary to migrate to multiple software branches at the same time, and the workload of maintenance increases exponentially with the increase of software complexity and projects.

In the stage of frequent changes in the demand of intelligent driving track, the time period is very short; However, there will be no reduction in the quality requirements for output. This challenges our software architecture. We urgently need a software architecture that can support multi-project parallel development and rapid iteration.

How to solve this problem? We found inspiration on AUTOSAR. The core idea of AUTOSAR is the decoupling of hardware and software. The bottom layer realizes the software functions that are strongly related to hardware, and abstracts them into standard interfaces for the upper layer. The upper ECU and the application layer are almost insensitive to the difference of the lower hardware, which makes the AUTOSAR architecture software migrate on multiple hardware platforms.

Secondly, the core idea of AUTOSAR is the modularization of software and standardization of interfaces. AUTOSAR is divided into hundreds of software modules, and the function definition of software modules is very clear, and the data between software is exchanged with the defined standardized interfaces. When the software of one module is changed, the influence on other software modules and even the whole controller software is controllable.

Platform of MCU software for intelligent driving domain controller

Our MCU platform software architecture refers to the idea of AUTOSAR. Firstly, a set of loosely coupled software architecture is needed. The so-called loose coupling means software modularization, and the function definition of each software module must be clear. The exchange interface between modules is standardized and managed in a unified file according to the architectural method of AUTOSAR.

The second is the strong mainline software architecture. Referring to the software architecture idea of AUTOSAR, we divide our MCU software into different softwares according to the actual business requirements. A hardware platform has only one software, and a project has a separate software. The interface between is predefined and cannot be easily changed. To ensure that a set of software can be combined with different software of multiple projects.

The actual operation method of this software architecture is:

First of all, the BSW project of AUTOSAR is strongly related to specific projects and models, such as the number of communication buses, the configuration of communication matrix, the configuration of diagnostic protocol stations, the configuration of network management, etc. These configurations are different for each model. Therefore, the BSW engineering code of AUTOSAR is divided into BASE software and CDD software (including IOO abstraction of various hardware and data intervention of sensors, etc.). These modules are only related to the hardware platform and have no direct relationship with the project. The application layer software isolates the differences of signal interfaces of various vehicles through the signal abstraction module, which makes most application layer software project-independent.

In addition, there are some special software modules, such as time synchronization module. All items of the time synchronization scheme in our domain are consistent; However, the cross-domain and vehicle-domain schemes have different projects. For this kind of module, we split the software of a module into two parts for maintenance, provided that the interfaces between the software must be well defined, so that multiple projects can share one software, and different BASE software can work normally together.

Under this software architecture, the methods of software management are different. A hardware platform has only one software warehouse, and each project has a separate BASE software warehouse. Only when the software is merged can the final MCU software output be obtained. Its advantage lies in that the mainline optimization is directly effective for each project. The challenge is how to ensure that the changes on the main line are not wrong for each project, which requires agile development and CICD to ensure.

Agile development of MCU software for intelligent driving domain controller

The software version delivery of the whole intelligent driving domain controller basically follows the traditional automobile micro-model development, from the initial demand input to software design, software development, software testing and overall acceptance, and a version lasts about 2-3 months. In the big cycle, we iteratively split the MCU software version into weekly agile development cycles.

The cycle of agile iteration in weeks can also be refined to the development iteration in days. Baidu has its own set of code management tools. When we push the code, it triggers the continuous integration compilation pipeline to get the compiled results and outputs. At the same time, the system will automatically trigger to pull the latest code from the library every night and push it to the CICD test server. The test server will simulate the upper computer to deploy the software to the domain controller of the test bench, which has a full set of sensor environment and simulated vehicle environment besides the physical domain controller. After the deployment, according to the pre-set test flow, the MCU software is matched with the SOC terminal to conduct a set of systematic tests.

After the test, the server finally collects the test results, and generates an email report and pushes it to the corresponding person. When you go to work the next day, you will know whether there is any problem with the previous day’s cooperation code. In addition to the bench test, we have a lot of driving tests every day, and the data generated in the test and the problems will be uploaded to the data center, and special managers will distribute the problems and data to the corresponding module leaders. After analyzing the data, the R&D personnel locate the problems, and then arrange the repair plan of the problems into the agile iterative process according to the priority, so as to carry out iterative development of the software, quickly deploy the new output to the R&D vehicle, and then carry out closed-loop verification.

At present, automakers pay more and more attention to software self-research, especially in the field of automatic driving. Some automakers choose Baidu as a supplier of software and hardware for intelligent driving systems; At the same time, I hope to participate in the development of some intelligent driving functions.

We also have some successful experiences in the project. First, OEM will generate the document of our intelligent driving domain controller, and then build an algorithm model to generate SWC articles in AR file format. And the final C code will be generated, and the ECU document will be given to Baidu. After we import the AUTOSAR development configuration tool, we can generate the technical engineering of MCU AUTOSAR and develop the software of MCU. Then compile it into a black-box project and give it to the OEM. The OEM will add the black-box project to the code generated by them for integration and compilation. After the compilation is passed, it will do its own module test. After the test is passed, it will give their model code compilation process to Baidu in the form of a black box. Then we will do the final integration, compilation and MCU software output, complete the integration test of the entire MCU domain controller, and deliver the test to the automobile factory, and then do the vehicle-level test.

Wu Changlong’s keynote speech "Software Platformization and Agile Development of Intelligent Drive Controller Based on AUTOSAR" delivered at the 4th Software-Defined Automobile Forum and AUTOSAR China Day in March 14 -16, 2023. )

　　As a new favorite of the family, computers have entered the homes of ordinary people. However, due to the lack of basic knowledge of home computers by ordinary users, some seemingly casual actions may directly lead to instant "paralysis" of computers and even damage human health.

　　Misunderstanding 1 Clean the screen with anhydrous alcohol

　　When the monitor is used for a long time, it is inevitable that there will be dust and stains. Many users think that alcohol, especially high purity (above 95%) is the best cleaner. On the contrary, there is a special protective coating on the screen of the current flat panel display to prevent static electricity and dazzle light. If alcohol is used for cleaning, it is easy to destroy the coating, but the display effect of the display is greatly reduced. In fact, the screen of the monitor, including its shell, cannot be cleaned with solvents such as alcohol, gasoline and washing powder. There is a special cleaner for monitors in the supermarket. Don’t use ordinary thick towels when cleaning the screen, you can wipe it with glasses cloth with better texture.

　　Myth 2: The chassis is exposed to heat.

　　When the computer is running, especially in summer, its heat dissipation is very large. Some computer enthusiasts directly open the chassis in order to strengthen heat dissipation and facilitate hardware disassembly. Although this method solves the problem of heat dissipation, the "gut opening" of the chassis exposes the hardware, which is easy to accumulate dust, and dust will become the "killer" of the computer over time. In addition, this practice is also harmful to human health. As we all know, CPU, motherboard and power lamp hardware are all high electromagnetic radiation sources, and the chassis can shield most electromagnetic radiation. If you let your body directly "receive" high electromagnetic radiation just to dissipate heat, it will not pay off.

　　Myth 3: Cover the dust cover after shutdown.

　　When a new computer enters the home, many people will protect it, especially paying attention to dust prevention measures. Dust cover is of course one of the necessary items, but it is not advisable to cover it immediately after shutdown. Although the mainframe has stopped running after shutdown, there is still a lot of heat in the chassis and the back cover of the monitor, and the temperature of various electronic components is very high, which needs to be cooled gradually. If you cover it with a dust cover immediately, it will easily hinder the heat dissipation of the hardware and even seriously affect its service life. It is best to turn off the machine for 1-2 hours and wait until the heat in the chassis is basically dissipated before using the dust cover.

　　Misunderstanding 4 Hot-swappable peripherals with electricity

　　When performing various hardware operations, some users often plug and unplug the mouse, keyboard and various serial and parallel port devices of PS/2 interface in standby mode. These operations seem normal, and actually have a certain "lethality" to the computer host, which may cause the system or hardware to work abnormally, and may even cause damage to the hardware interface or motherboard. In fact, except for USB, IEEE1394 interface and serial hard disk, all kinds of peripherals of ordinary desktops are not hot-swappable with electricity, so it is suggested that you must operate correctly when the power is turned off to avoid unnecessary losses.

Mobile phone battery is not durable? 14 tips to extend battery life

　　If the user wants to extend the effective service life of the battery, besides the quality of the charger, the correct charging method is also essential, because the poor quality charger or the wrong charging method will affect the service life and cycle life of the battery. Here are the skills that the author has compiled to extend the service life of the rechargeable battery of the mobile phone:

14 tips

　　1. Please use the charger of the original factory or a reputable brand, and use the special charger for lithium batteries, and follow the instructions, otherwise the battery will be damaged or even dangerous.

　　2. If the newly bought mobile phone battery is lithium ion, the first 3~5 times of charging is generally called the adjustment period, and it should be charged for more than 14 hours to ensure the full activation of lithium ion. Lithium-ion battery has no memory effect, but it has strong inertia. It should be fully activated to ensure the best performance in future use.

　　3. Before the battery leaves the factory, the manufacturers have activated it and pre-charged it, so all the batteries have surplus electricity. Some friends say that the battery is charged according to the adjustment period, and the standby time is still seriously insufficient. Assuming that the battery is indeed a genuine battery, in this case, the adjustment period should be extended and then fully charged and discharged for 3~5 times.

　　4. Before charging, the lithium battery does not need special discharge, and improper discharge will damage the battery. Try to charge slowly when charging, and reduce the fast charging mode; Time should not exceed 24 hours. After three to five complete charge and discharge cycles, the chemicals in the battery will be fully "activated" to achieve the best use effect.

　　Some automatic intelligent fast chargers only indicate that they are 90% full when the signal light changes. The charger will automatically change to charge the battery at a slow speed. It is best to use the battery after it is fully charged, otherwise it will shorten the use time.

　　6. Many users often leave their mobile phones on when charging. In fact, this will easily hurt the life of their mobile phones, because during the charging process, the circuit board of the mobile phones will heat up. At this time, if there is an external phone, it may produce instantaneous backflow current, which will damage the internal parts of the mobile phones.

　　7. The life of the battery depends on the number of repeated charge and discharge, so we should try to avoid charging the battery when there is surplus electricity, which will shorten the life of the battery. When the phone is turned off for more than 7 days, the battery of the phone should be fully discharged before use.

　　8. Mobile phone batteries all have self-discharge. When not in use, the Ni-MH battery will discharge about 1% of the remaining capacity every day, and the lithium battery will discharge 0.2%~0.3% every day. When charging the battery, try to use a special socket, and don’t share the socket with household appliances such as TV sets.

　　9. Although the mobile phone is within the network coverage area, it can no longer accept and make calls when the mobile phone is turned off and charged. At this time, you can use the mobile phone’s no-call transfer function to transfer the mobile phone to the fixed phone around you to prevent the loss of incoming calls. This method is also applicable when the mobile phone is not in the network coverage area or the signal is weak and temporarily unable to connect.

　　10. Don’t expose the battery to high temperature or cold, like in dog days, don’t put the mobile phone in the car and expose it to the scorching sun; Or take it to an air-conditioned room and put it in a place where cold air blows directly. When charging, it is normal for the battery to be a little hot, but it cannot be subjected to the "suffering" of high temperature. In order to avoid this, it is best to charge at room temperature and don’t cover anything on the phone.

　　11. nickel cadmium (N iCd) battery must be fully charged before charging and fully charged after recharging.

　　12. If the mobile phone battery is left unused for too long, it is best to apply to the mobile phone maintenance department for a live treatment of the battery, or you can use a DC constant voltage device yourself to adjust the voltage to 5~6V and the current to 500~600mA to connect the battery in reverse. Note: release it at the touch, and repeat it for up to three times. After this treatment, use the original charger for "adjustment period" charging.

　　13. When charging, the longer the better. If the battery without protection circuit is fully charged, it should be stopped, otherwise the performance of the battery will be affected by heat or overheating.

　　14. Lithium-ion battery must use special charger, otherwise it may not reach saturation state, which will affect its performance. After charging, avoid placing it on the charger for more than 12 hours, and separate the battery from the mobile phone when it is not used for a long time.

　　The above 14-point mobile phone charging method has been proved by practice to effectively extend the life of mobile phone batteries, and friends who need it can try it, saving money and resources.

　　Shantou, China, April 15 (Chen Qiren, Yao Xiaoli) Guangdong Shantou police reported on the 15th that Shantou police recently successfully smashed a telecommunication network fraud gang that frequently committed crimes, arrested 10 suspects, seized 93 mobile phones and 83 bank cards involved, involving 11 provinces and cities such as Guangdong, Fujian and Shandong, and initially identified 133 cases involved.

　　According to Shantou police, in recent years, with the rapid development of mobile Internet, criminals have used communication tools to commit online fraud from time to time, which has made many people deceived and lost their money.

　　Shantou police investigation found that a telecommunication network fraud gang hidden in Shantou surfaced. The gang bought a large number of bank cards, mobile phone cards, "Lacarra" credit card machines and other crime tools from the Internet, rented a number of houses in Shantou city as dens, published false information about "online car purchase" through public network platforms, and made false web links. The cases involved 11 provinces and cities such as Zhejiang, Henan and Hebei, and the amount involved was huge.

　　After careful investigation, the police grasped seven criminal dens of the gang in Shantou. On April 8, Shantou police concentrated more than 140 elite police officers to form seven arrest teams, and arrested seven dens of the fraud gang at the same time, successfully arresting 10 members of the criminal gang, including Wang Moufu, and smashed this mega-telecommunication network fraud criminal gang in one fell swoop.

　　Zhan Yihua, deputy director of Shantou Public Security Bureau, said that telecommunication network fraud is concealed, and many online fraud platforms set their backstage outside the country, which makes it difficult to handle cases and investigations. At the same time, criminal gangs transfer funds through third-party payment, which also brings troubles to police investigation and evidence collection.

　　"Telecommunication network fraud is often aimed at ordinary people. When a phone call comes, the citizens will be cheated of a lot of savings." Zhan Yuhua said.

　　The police reminded the public not to trust the commodity information on the Internet that is obviously lower than the market price; Online shopping should be carried out on a qualified and guaranteed online shopping platform; Don’t pay in advance without knowing the real situation of online shopping sales; If you find a crime of fraud, you should report it in time.

　　Guangdong and Guizhou cooperated to forge a new road, and Rongjiang merged into Greater Bay Area. At 2: 35pm, accompanied by the cries of tens of thousands of spectators, Rongjiang Villagers Team and Hong Kong Stars Team jointly staged the first football match and kicked out the first kick. This is a friendly and harmonious match between Rongjiang County to build Guizhou into the main position of Guangdong-Hong Kong-Macao Greater Bay Area’s "bridgehead" and integrate with Greater Bay Area.

　　According to the arrangement of the event, the second game was played by Guizhou University Ecological Tea Team against Guangxi University Sugarcane Juice Team. It is understood that Guizhou University has helped Rongjiang County for more than ten years, helping Rongjiang win the battle against poverty, and now it is an important helping force for rural revitalization in Rongjiang County. Historically, due to the spread of war, Guangxi University moved to Rongjiang in 1944 and brought football to Rongjiang, which is the root of Rongjiang football development. This game is a friendship game between Guizhou and Guangxi universities.

　　The third game is the match between Qiandongnan Soup Team and Guicheng Bamboo Shoot Team in Foshan City. Foshan City helps Qiandongnan Prefecture, Guangdong and Guizhou are concentric, and mountains and seas are connected. This competition is a dream-building competition for cooperation between the east and the west. At about 8: 30 p.m., Rongjiang Fenfen Team and Nanchang Fenfen Team, both old revolutionary base areas and food capitals, made their debut, contributing to the fourth game of the day, which was not only the inheritance of red blood, but also the collision of food culture.

　　It is understood that the competition time of Guizhou Rongjiang Food Football Friendly Tournament (the first season) is from August 13 to October 28, 2023, with a total of 19 games. Considering the influence of the game, the history of Rongjiang football, the cooperation between the east and the west, the theme of the game and other factors, the organizers invited four games in the first week, aiming at producing a wonderful opening game and proofing the subsequent friendly matches.

　　On August 13th, spectators dressed in national costumes were watching the game. Xinhua News Agency reporter Liu Xushe

　　The full name of Guizhou "Village Super" is Guizhou Rongjiang (Sanbao Dong Village) and American Country Football Super League, which is a village-level football competition mainly organized and hosted by Rongjiang villagers. Since the opening match started on May 13th, the related content has been viewed more than 30 billion times on the whole platform, making it a "phenomenal" sports event. Before the food football friendly match, Rongjiang received a total of 798 teams, and 297 teams were confirmed to be able to participate, including 83 teams in Guizhou Province and 214 teams outside the province.

　　Xu Bo, the county magistrate of Rongjiang County, said in an interview earlier that the purpose of holding the friendly match of gourmet football is to make the brand of "Village Super" bigger and stronger, and gather wisdom to make "Village Super" a sustainable event, so that the bonus of "Village Super" can be shared in many places.

　　Beijing, May 31st, the client of Zhongxin. com, starting from tomorrow, the time will enter June. At the same time as the hot summer, there are a number of favorable policies, such as high-temperature allowance and new rules for online car rental, which will bring real "coolness" to your summer in terms of income and travel.

　　High temperature allowance began to be distributed.

　　Every summer, the distribution of high temperature allowance is concerned by the public. In most parts of China, with the arrival of June, the money will be credited to the workers’ accounts one after another.

　　According to the Management Measures for Heatstroke Prevention and Cooling Measures revised in 2012, if the employer arranges the workers to engage in outdoor open-air operations in hot weather above 35℃ and cannot take effective measures to reduce the workplace temperature below 33℃, it shall pay the workers a high-temperature allowance.

　　Judging from the distribution time of high temperature allowance, there are also differences in different places due to differences in climatic conditions. For example, the distribution period in Beijing, Shanxi and other regions is from June to August; Jiangsu, Shanghai, Gansu and other places are from June to September; Guangdong, Guangxi and other places are from June to October.

　　In addition, Jiangsu, Tianjin and other provinces also raised the high temperature allowance this year.

　　The network car is included in the taxi service assessment system.

　　The safety and convenience of taxi travel are also concerned by the public. The "Measures for the Assessment of Taxi Service Quality and Credit" will be implemented on June 1, and the online car will be included in the taxi service assessment system, but the assessment of the online car driver will only be "returned to the furnace".

　　Specifically, the "Measures" will include the new format of the network car in the assessment, and clarify that both the network car and the cruise car need to carry out the service quality reputation assessment. In the indicator setting, the common requirements of the network car and the cruise car are considered, and according to the unique operating service characteristics of the network car, the indicators such as data access and operating service information disclosure are tailored.

　　In addition, the "Measures" also adjusted the distribution setting of the assessment scores of taxi companies, increased the assessment scores of providing operational services for passengers and other matters, and guided drivers to actively improve service quality.

　　It is worth mentioning that the "Measures" stipulate that drivers should be assessed for compliance with laws and regulations, safe production, business behavior and operational services. If taxi drivers score less than 3 points during the assessment period, they should receive training as required.

　　English "national standard" will be implemented.

　　How to evaluate the English level of China people? On June 1st, the first English proficiency assessment standard for English learners in China, China English Proficiency Rating Scale, will be launched.

　　It is understood that the scale was released by the Ministry of Education and state language commission in April, which graded English learners and users in China in detail. Among them, the English language ability of English learners and users in China is divided into one to nine grades from low to high, which are classified into three stages: basic, improvement and proficiency.

　　According to the relevant person in charge of the Examination Center of the Ministry of Education, the scale is like a competency scale, which will play an active role in improving the quality of examinations, promoting the docking of domestic and foreign examinations, promoting multi-evaluation and feedback teaching, and is conducive to achieving "quantity balance".

　　Drone access conditions are reduced.

　　In recent years, the unmanned aerial vehicle market in China has grown rapidly, and its application in agriculture, electric power, surveying and mapping, security and other fields has become increasingly mature. However, the relevant regulations on unmanned aerial vehicles engaged in commercial flight activities have always been a blank.

　　From June 1st, the Administrative Measures for Operational Flight Activities of Civil Unmanned Aerial Vehicles (Provisional) issued by the Civil Aviation Administration will be implemented soon. The "Measures" standardize the access and supervision requirements for unmanned aerial vehicles to engage in operational general aviation flight activities, and enterprises engaged in operational flight activities will be legal and compliant from now on.

　　What impact will A-shares enter Morocco?

　　In June, there is another financial event worthy of attention.

　　On May 15th, MSCI (Morgan Stanley Capital International Company, also known as "morgan stanley capital international Company" in China) announced the adjustment results of semi-annual index constituent stocks, showing that 234 A-shares were confirmed to be included in the MSCI index system and officially implemented on June 1st.

　　According to the data, MSCI index is compiled by Morgan Stanley International Capital Corporation (MSCI), which is often used by mainstream international funds as investment guidance or tracking index, and their own ETF funds (transactional open index funds) are allocated according to MSCI index. From next year, overseas funds can also purchase A shares directly through MSCI index.

　　In the eyes of the industry, the participation rate of overseas institutional investors will continue to rise after A shares are included in the MSCI index. In the medium and long term, the A-share market will become more mature, the liquidity will increase, and the market trend will gradually be dominated by short-term market noise and driven by basic factors.

To say that the person who can climb the hot search list every day in recent days is not the latest young top stream, but Murong Yunhai-Hans Zhang, who was known to the whole country with meteor rain more than ten years ago.

No matter which entertainer is in the entertainment circle, it must be a good thing to go online for hot search. After all, it means higher exposure. Unfortunately, it’s not that Hans Zhang has anything good to do with the hot search. The hot topic of this round of search is the drama Gentlemen of East Eight Districts, which was produced, written and starred by Hans Zhang himself.

A TV series with such a high volume of content has attracted everyone’s attention, not because it is so good-looking, but because it is beyond measure. Winning the historic score of 2.1 points has successfully become the lowest record in domestic film and television dramas in Douban score. There is more than a little bit of sadness in the play, and the source of all this is of course our producer, screenwriter and starring Hans Zhang.

In this regard, some netizens teased that Hans Zhang had taken over the greasy work of domestic male stars in an all-round way, which can be called an unprecedented and unprecedented master. But the question is, is Hans Zhang just greasy? In fact, his biggest problem is not greasy, but no entertainment spirit.

Said he didn’t have a strong spirit of entertainment, there have been two well-known events, which reflects this.

Once it was an expression pack incident.

Hunan Satellite TV followed suit to shoot Korean dramas, and produced a super-power TV series similar to You from the Stars, so it invited Hans Zhang to star in this drama-Different Handsome Man. Most netizens mentioned this drama, and they should not remember it at all.

However, there is a special expression pack in this drama, that is, looking back and smiling from Hans Zhang. This screenshot showing 18 big white teeth has made everyone spoof. Netizens are actually not malicious, they just think it’s fun. Many stars, such as Jacky Cheung and Z.TAO, have experienced it and let the whole network take it as an expression pack. Stars, their existence is to let the audience entertain.

It happened that Hans Zhang was unconvinced and blacked out several marketing numbers that forwarded this emoticon. Some of them went too far, so he simply sued them directly. Later, he also responded to this incident and explained plausibly: "At that time, I just met a low state and was teased by others. During that time, I was very uncomfortable. I slept for three hours every day and took sleeping pills every day."

However, when netizens heard him talk like this, they didn’t feel that Hans Zhang at that time was distressing, but it made people feel that he couldn’t afford to play. There are more people in the entertainment circle than Zhang Hanhong, who are subjected to black, slander, rumors and personal attacks. I have never seen others come forward to find so many reasons and excuses for themselves.

There was a discordant episode before the big explosion drama "Shanshan is coming" was broadcast and a preview was released in advance. There is a clip in the preview, in which Feng Teng, the hero played by Hans Zhang, said to Shanshan, the heroine played by Zhao Liying, "I want everyone to know that this fish pond has been contracted by you." Then, a film and television blogger intercepted the video and sent a long picture saying, "I really don’t understand, there is nothing to show off."

Anyone with a discerning eye can see that this is just a joke of a blogger who spits. When the TV series is combined in the later stage, there is a reason for the hero to say this sentence. He wants to reassure his beloved woman and use the fish pond as a metaphor.

And Hans Zhang didn’t have the courage to hold his breath at all. He went to Weibo directly, and even swore, "Because I am your good father, my sons go out every day to embarrass themselves and lose their moral integrity. How can dad earn money to support you if he doesn’t pretend?" Originally, it was a small-scale spit, but as a result, a stone stirred up a thousand waves at once, making countless people think that he was so stupid. Today, the blogger is on Hans Zhang’s Lahei list.

Artists walking in the entertainment circle, if they don’t have any entertainment spirit, then they should take pictures with peace of mind, isolate themselves from the audience, try to show people with their roles, take filming as their work, and don’t expose their temperament. If there is no way to be single-minded and just shoot movies, you should keep interacting with fans and netizens. Even if you can’t cultivate an invulnerable diamond heart, you should at least have the entertainment spirit of being willing to play with the public.

World Football Day

These world cup cold knowledge

Do you know all about it?

Although the cold winter is coming, the football enthusiasm has not diminished. Tonight we will have a wonderful match between Croatia and Brazil, and today is the World Football Day recognized by the United Nations. Come and learn about the cold knowledge about the World Cup with Xiaobian and feel the charm of football!

Why is this year’s World Cup in winter?

In the past memory, the World Cup is always associated with summer, full of sweat, passion, beer and cheers. This time, however, FIFA World Cup Qatar 2022 was held in winter, which was mainly due to the Qatari climate.

Qatar is located in the desert area of the Middle East, with a tropical desert climate. In summer, the temperature is generally 25-46 degrees Celsius, and the highest temperature can soar above 50 degrees Celsius. This is really too hot for a player who wants to run for 90 minutes, and there is even the danger of heatstroke.

Of course, even in winter, the highest temperature in Qatar at the end of November can exceed 30℃, but the stadiums in Qatar are basically equipped with cooling systems to ensure that football players can play at a suitable temperature.

Why do players spit water?

This scene often occurs in football matches. Players take a sip of water and then spit it out immediately like gargling. Many friends will misunderstand when watching the ball. "Why do they spit everywhere?"

In fact, this is a way for players to drink water. The professional name is "carbohydrate gargle", which can effectively improve sports performance and relieve sports fatigue. It is a "scientific plug-in" for athletes on the field. They need to cheat their brains in this way without affecting their state, in order to quickly restore their physical functions and continue to play.

Why is there no British team in the World Cup?

There is no British team in the World Cup because there is no only football association in Britain.

In 1863, Britain, as the birthplace of modern football, established the world’s first football association: the English Football Association. In 1886, the football associations of England, Scotland, Wales and Northern Ireland jointly established the World Football Council and made unified rules. Later, FIFA generally joined football associations everywhere, so four football teams in Britain were invited to participate in the World Cup, namely, England, Scotland, Wales and Northern Ireland.

What is offside?

FIFA World Cup Qatar 2022 is in full swing, attracting countless fans to watch. In the first half of Argentina’s game against Saudi Arabia, it was blown offside six times, which made people confused. Many new fans will ask a question, what is offside?

Offside refers to the moment when the attacker passes the ball, the receiver stands closer to the goal than the penultimate defender, and at the same time closer to the opponent’s goal than the ball, and tries to prepare for the attack from this position. In other words, offside is an act that has a clear purpose, produces intentions quickly and puts them into practice. On the court, it is often seen that players are sentenced to offside because they start too fast and fall into the offside trap of their opponents.

The offside rule was formulated by the British Football Association in 1870. In the football match at that time, the audience often saw such a scene: when one side launched an attack, most of the attacking players had gathered in front of the other side, ready to start shooting when they received the ball, so the game between the two teams was mainly concentrated in front of the goal, and there was little wonderful cooperation. The offside rule is precisely to adjust this excessively unbalanced offensive and defensive relationship and make the game more exciting.

CCTV News:In May, with the temperature rising gradually, everyone’s "fruit basket" became more and more abundant, and the competition in the fruit market became more and more fierce. Next, pay attention to the series report "Consumer Market Survey and Fruit" War ".Colorful fruits, which is the delicious representative of early summer? Everyone has different answers.

However, when it comes to the fruit that was once known as "noble", you can’t help but mention cherry. Because of its high price, cherries once became the ceiling of "fruit freedom". Recently, cherries planted in various places have been listed one after another, so what is the current sales volume and price situation? Come and see our reporter’s investigation in Beijing.

At four o’clock in the morning, Beijing Xinfadi Farmers’ Market has been very busy. In the cherry sales area, buyers who come to purchase goods are in an endless stream, and cherry sellers are busy. A batch of cherries that Li Xiaojiao just entered at 10 o’clock the night before was about 3,000 kilograms, and it was almost sold out at dawn.

Zhang Lei is a buyer of a fruit supermarket in Fengtai District, Beijing. Recently, he entered the cherry peak season, and the sales volume of the supermarket gradually increased. Today, he plans to purchase more different varieties of cherries. However, because of the late arrival, there are fewer products to choose from.

A number of merchants told reporters that at present, the newly-developed market mainly sells cherries planted in the open air in Shandong and cherries planted in the cold shed in Dalian, and the sales situation has been very optimistic since listing.

　　　　　　 The reporter learned that compared with when it was first listed in March, the price of cherries at this time has dropped a lot. Take Meizao cherry, which is more popular in the market, as an example, the latest price per catty is about 30 yuan lower than that in March. In the following June and July, after a large number of cherries planted in the open air in Dalian and other places were listed, the sales price of cherries would drop.

Domestic cherries with delicious taste and excellent price "meet" imported cherries

In fact, a few years ago, domestic cherries were once neglected, and many consumers preferred imported cherries. In recent years, the market share of domestic cherries has been increasing. What makes domestic cherries catch up?

In this fruit store in Dalian, there are different kinds of domestic cherries on the shelves. The person in charge told the reporter that in the past few years, the sales situation of cherries was hot, which was more favored by consumers. This year, the sales of cherries in supermarkets increased significantly.

According to the reporter’s understanding, in recent years, the planting level of domestic cherries has been continuously improved, and the quality and flavor of fruits have been gradually improved. Moreover, the characteristics that the origin of domestic cherries is close to the consumer market also meet the requirements of consumers for freshness.

Liu Changhao, manager of a fruit dessert sales store in Dalian, Liaoning Province:Domestic cherries have the advantage of localization and are closer to consumers’ tables. It can be reached in a few hours at the earliest, and the farthest is like Guangdong in the south, which can be reached in two days by air transport. Cherries are mainly imported from abroad, so the transportation time will be longer.

In addition to the fresher taste, the transportation cost of domestic cherries is much lower than that of imported cherries, which also brings a certain price advantage to domestic cherries. Compared with the average selling price of cherries in winter this year, the average selling price of cherries in summer is basically about 20 yuan less than that of cherries in winter.

According to industry insiders, with the improvement of the quality and output of domestic cherries and the decline in prices, the market share of domestic cherries is constantly improving.

　　　　　　 Pan Fengrong, researcher of Dalian Academy of Agricultural Sciences, Liaoning Province:Especially in Dalian and Yantai, which are key producing areas, local people can’t eat so much, so they have to be shipped to the whole country. Basically, we are consuming so many cherries.

Farmers who choose good trees and produce good fruits have planted "big cherry" by experimental grafting.

Better flavor, higher quality and more advantageous price make domestic cherries the "king" of the fruit market, and all these are inseparable from the improvement of cherry planting technology. Next, we will follow the reporter to Dalian, Liaoning Province to uncover the mystery behind the domestic "big cherry".

CCTV reporter Ding Dong:I am now in a cherry planting greenhouse. The cherries in the greenhouse are basically ripe. You can see that this fruit is very bright and full. Such a cherry tree can bear about 40 kilograms of cherry fruit. Now we come to the open-air plantation, and the cherries planted in the open air are not mature yet. The staff told me that it will be another month before these cherries can be harvested.

Cong Dayu, a cherry farmer in Qidingshan Village, Dalian, contracted two planting greenhouses and a part of open-air plantations, with a total planting area of about 50 mu. After 8 years in business, Cong Dayu has carried out grafting experiments on cherry fruit trees many times.

Cong Dayu, a cherry grower in Qidingshan Village, Dalian City, Liaoning Province:The largest single fruit produced at the earliest time should be about 15 grams, and now we have risen to a higher level, and the maximum weight of a single fruit may reach 20 grams. Now the income should increase by more than 20% than before.

The growth of cherry trees is greatly influenced by fertilizers. This enterprise in Dalian, Liaoning Province owns 70 mu of cherry plantation. Combining the dairy industry chain and fruit planting industry owned by their own enterprises, they developed bio-organic fertilizer using milk, pomace, cow dung and soybean meal to cultivate cherry trees.

Jiang Wei, chief agronomist of fruit brand under Xinle Group in Dalian, Liaoning Province:Its nutrition is very comprehensive, including protein, some amino acids, some trace elements, and even calcium growing in trees.

Under the ecological cycle, the use of biological fertilizer not only reduces environmental pollution, but also improves the flavor and taste of cherry.

　　Xu Zechen’s "Going North"

　　Chen Yan’s protagonist

　　Liang Xiaosheng’s In the World

　　Since the 10th Mao Dun Prize for Literature was announced, the discussion around the five winning works has never stopped. People are more concerned about whether these works can be put on the screen and let a wider audience read the stories. In recent years, with the upsurge of big IP and traffic drama fading away, the market of realistic film and television dramas is picking up. Will serious literature represented by Mao Prize works become the new IP "toon" in the film and television industry?

　　Mao Dun’s literature prize-winning works were once rich mines of film and television dramas. The winning works of the 3rd Mao Dun Literature Prize and Ling Li’s Young Emperor were adapted into TV series by Liu Heng, and the 3rd and 4th Mao Awards, Ordinary World and White Deer Plain, were adapted into TV series for broadcast, all of which gained both ratings and word of mouth. Mai Jia’s "plot against" was made into a TV series even before he won the Mao Award. The reporter learned through interviews that at least three of the five novels that won the Mao Dun Literature Award have signed out the film and television copyright and entered the process of film and television adaptation.

　　Yao Xiaofeng and Xu Zechen have the same view on adaptation.

　　The novel "Going North" published by Beijing October Literature and Art Publishing House and written by Xu Zechen, a powerful post-1970s writer, has won the Mao Dun Literature Award and the "Five One Projects" Award in succession. "Going North" tells a century-old story between several families on the Beijing-Hangzhou Grand Canal with two clues of history and present. It is not only a big book about "a river", but also a spiritual history about "a nation". As early as 2018, shortly after the publication of "Going North", this book was taken by the Enlightenment Film Industry and the copyright was successfully signed. Zhang Shuwei, the producer of the drama "Going North", told reporters, "This is not a particularly commercial act, but because the director and the original author are highly unified in spirit, which is the biggest feature of this project."

　　The director of the drama "Going North" is Yao Xiaofeng, who has directed plays such as Little Husband, Tiger Mom and Cat Dad, and Taking Dad to Study Abroad. Zhang Shuwei said that after reading the original novel, Yao Dao liked it very much, and because he and Xu Zechen were both from Jiangsu, they felt very sympathetic, so they made an appointment with Xu Zechen soon. "The director’s vision of this play coincides with xu teacher’s. The director thinks that what attracts him most is the temperament and grand framework of the novel. They have many consistent ideas on the film adaptation of the novel." Zhang Shuwei said, therefore, the whole process of copyright granting is very smooth.

　　At present, the drama version of "Going North" is in the process of creating the first draft of the script outline. Zhang Shuwei admits that the original novel has a large framework and a long time span, and it is no small challenge to adapt the TV series. In October, she plans to work with the director and screenwriter, and try to invite Xu Zechen to go all the way north along the Grand Canal to visit the places mentioned in the book and sort out her creative ideas. The film version of "Going North" is also in the early stage of preparation.

　　Chen Yan’s two novels become sought-after IP

　　Just like Going North, the film and television licenses for The Leading Role by Chen Yan and The World by Liang Xiaosheng were completed a year ago. At present, Chen Yan, who is the party secretary and vice chairman of the Chinese Dramatists Association, is a playwright himself. The TV series of the same name adapted from his modern Shaanxi opera Xijing Story was broadcast at the end of last year, and the response was good. Nowadays, Chen Yan’s two novels, Putting on a Stage and The Leading Role, which are based on the Shaanxi Opera Troupe, have entered the film and television process. The TV series "Dressing Taiwan" is directed by Li Shaofei, written by Ma Xiaoyong and starring Zhang Jiayi and NiNi. It is a TV series with a strong brand of "Shaanxi School". In an interview with reporters, Chen Yan said that "Loading Taiwan" has been finished and entered the post-production. The copyright of the film and TV series of "The protagonist" was signed a year ago and is currently in the stage of script creation. "Novel conversion film and television, is the film and television artists. I certainly hope that the adaptation can respect the original work. " Chen Yan said.

　　Liang Xiaosheng’s million-word masterpiece "In the World" is known as "fifty years’ life history of China people". As early as the end of last year, Liang Xiaosheng signed the full copyright contract of In the World to a company named Uncultured. According to the company’s official website, the TV series "In the World" will join hands with Tencent Pictures and be directed by in the name of people director Li Lu. Liang Xiaosheng had previously worked as a TV adaptation of his own works "Annual Rings" and "Educated Youth", but he also said in a public lecture that he no longer intervened in the film and television adaptation of "The World", but only participated in the adaptation seminar.

　　Among the five works that won the Mao Dun Literature Prize this year, the film adaptation of Li Er’s Ying Wu Xiong and Xu Huaizhong’s Leading the Wind is still unclear. The reporter asked Song Qiang, director of the planning department of People’s Literature Publishing House, the publisher of the two books. He said that after winning the prize, someone had come to negotiate the film and television copyright, but it was not clear whether to sell the copyright. As for "Brother Ying Wu", he thinks that this work is relatively large and may not be suitable for adaptation into a TV series.

　　The adaptation of serious literature to film and television should not be high and low.

　　Professor Li Shengli, director of the Department of Radio, Television and Literature of China Communication University, believes that taking the adaptation of works such as Massage, White Deer Plain and Ordinary World as an example, we can find that the overall acceptance effect of these Mao Prize works after IP adaptation is both well-received and applauded, but on the whole, Mao Prize works and TV dramas are art categories with similarities and differences, and their main acceptance groups have similarities and differences. "For a long time, there will be a huge gap between the main recipients of TV dramas and the recipients of serious literature. Of course, having excellent serious literary works as the foundation will make a good start for the vigorous development of realistic TV series in China in the future. Without this foundation, it is only possible to create truly excellent TV dramas by an excellent adaptation and creation team. "

　　Li Shengli said that there is no clear boundary between serious literature and non-serious literature. From the specific works, some serious literary works also have the potential of popular culture, and these works are the easiest to be adapted into excellent TV dramas; Other serious literary works can be adapted by borrowing some points that are suitable for market acceptance, so that it is possible to make a film and television drama that is both good and popular, otherwise, it may become a spring snow with high and low music.
