For a long time, the college entrance examination has been an important topic of concern to all students and parents. Nowadays, the college entrance examination enrollment in 2019 has entered the final stage of volunteering. So, what is the development trend of the college entrance examination in 2019?

　　Recently, China Education Online released the "Report on 2019" (hereinafter referred to as the "Report"), showing that the number of applicants for the college entrance examination in 2019 exceeded 10 million, and the actual admission rate of the national college entrance examination in 2018 reached 81.13%, with some areas exceeding 90%. At the same time, with the deepening of the reform process of college entrance examination, the Ministry of Education has standardized special types of enrollment, tightened the policy of independent enrollment, and some colleges and universities plan to reduce their enrollment by over 60%.

　　The number of applicants for the college entrance examination exceeded 10 million, and the actual admission rate exceeded 80%

　　In 2019, the number of applicants for the college entrance examination returned to the order of 10 million again after 10 years.

　　According to the latest data released by the Ministry of Education, the number of applicants for the national college entrance examination in 2019 was 10.31 million, once again exceeding 10 million, setting a record high since 2010. However, since 2007, the actual admission rate of college entrance examination has been on the rise.

　　According to the Report, the actual admission rate of college entrance examination exceeded 80% in 2017, which also means that most college entrance examination students have the opportunity to receive higher education. In 2018, there were 7,909,900 college students enrolled nationwide, an increase of 3.87% over the previous year, and the actual admission rate of college entrance examination reached 81.13%. Although the actual admission rate of college entrance examination in some areas has declined slightly, it still remains at a high level. In addition, the actual admission rate of college entrance examination in some areas exceeds 90%, such as Hebei and Jiangsu.

　　It is worth noting that in recent years, the unfinished enrollment plan in some areas is more prominent. According to the "Report", taking Jiangsu and Hebei as examples, the number of unfinished enrollment plans in Jiangsu reached 42,000 in 2016, and it was controlled at around 20,000 in 2017 and 2018; The number of people who did not complete the enrollment plan in Hebei reached 28,000 in 2014, but it has dropped back to 0.75 million in 2017.

　　With the continuous expansion of the scale of higher education, higher education will enter the stage of popularization. According to the Report, China has built the largest higher education system in the world, and the gross enrollment rate of higher education has increased rapidly, which is about to enter the stage of popularization. In 1978, the gross enrollment rate of higher education was only 1.55%, and in 2002, it increased to 15% in just 24 years, from the elite stage to the popular stage.

　　The policy of special enrollment in colleges and universities is tightening

　　With the deepening of the reform process of college entrance examination, the Ministry of Education has made efforts to promote fair and scientific talent selection, and standardized special types of enrollment.

　　Many people call 2019 the "strictest" year in the history of independent enrollment. The Ministry of Education has made 10 strict requirements for independent enrollment, one of which is fairness and justice, and strictly controlling the enrollment scale.

　　According to the Report, in previous years’ independent enrollment, the actual enrollment of most colleges and universities was lower than the enrollment plan. In 2018, among the 79 self-enrollment colleges and universities that publicized the enrollment information, 76 colleges and universities did not complete the self-enrollment plan, with a total vacancy of more than 5,200. Through the data sampling of 70 colleges and universities that carry out independent enrollment, only two colleges and universities have the same plans as last year, and the rest have reduced their plans. Among them, the independent enrollment plans of 13 schools have been reduced by 60%, and Shanghai University has been reduced by 80%.

　　In addition, in 2019, the requirements for independent enrollment in colleges and universities generally increased. According to the Report, the minimum requirements for independent enrollment in Tsinghua and Peking University in 2019 have been significantly improved, and the scope of target students has been narrowed, and the maximum preferential margin has also dropped from 60 points in 2018 to 20 points. Physical fitness test has become a "standard" for independent enrollment assessment in colleges and universities. Twenty-six colleges and universities clearly stipulate in their independent enrollment brochures that failing to participate in the physical examination or failing to pass the physical examination results will affect the candidates’ independent enrollment qualifications.

　　With the deepening of the college entrance examination reform, the pilot work of comprehensive evaluation reform is gradually launched, the scope is constantly expanding, and the number of students enrolled is also rising. According to incomplete statistics in the Report, in 2019, a total of 99 colleges and universities across the country conducted comprehensive evaluation enrollment pilots, among which 14 colleges and universities conducted comprehensive evaluation enrollment for multiple regions, and the remaining 85 colleges and universities conducted comprehensive evaluation enrollment in their provinces.

　　It is worth noting that comprehensive evaluation has become the main enrollment method of individual colleges and universities. According to statistics, in 2018, among the nine ministries and commissions and universities from other provinces that implemented the "Trinity" comprehensive evaluation of enrollment in Zhejiang, the total number of "Trinity" enrollment plans of eight universities except Zhejiang University was 1,014, and the total number of unified enrollment plans of these eight universities was only 78.

　　Nowadays, the threshold for sending students is further improved. The "Report" pointed out that since 2014, the number of students who have been admitted to the country has started to slim down significantly, and it has been declining for five consecutive years; The number of students who walked in decreased from 6,759 in 2013 to 2,091 in 2018 (excluding heroic children and retired athletes). The number of colleges and universities that recruit students who are recommended to walk has also decreased to 78 in 2018.

　　The reform of college entrance examination has been promoted to the central and western regions, and its physical status has risen.

　　In April 2019, the third batch of college entrance examination reform plans for eight provinces and cities were finally announced. The scope of this pilot project has been further expanded to the central and western regions. According to the "Report", from the perspective of the number of applicants, the total number of candidates in the six provinces and cities started before, except Shandong and Zhejiang, is relatively small. The provinces and cities started this time are basically big provinces for college entrance examination, and the number of candidates is huge.

　　It is understood that the third batch of college entrance examination reform programs in eight provinces and cities is different from the previous six provinces and cities. The subject selection mode has changed from "3+3" to "3+1+2", and physics and history are the first choice subjects, so one must be selected; When enrolling students, plan, underline, file and enroll separately according to physical and historical categories. This move emphasizes the basic position of physics and history, and is expected to solve the problem of the decline in the number of physics candidates during the implementation of the college entrance examination reform plan in other provinces.

　　In this regard, the "Report" analysis pointed out that students who choose physics subjects will have more choices and guide more students to choose physics.

　　According to the Report, the six provinces and cities that initiated the reform of college entrance examination have announced the requirements for the selected subjects of college enrollment majors in 2020. Among them, the number of majors requiring required physics has increased significantly. Take the requirements of major selection in 2020 in 40 local undergraduate colleges in Shanghai as an example. A total of 558 majors involve the requirements of taking physics exams, among which 380 majors must choose physics, while only 65 majors must choose physics in 2017.

　　Based on the basic position of physics in scientific research, high-level universities often pay more attention to physics. By analyzing the top 10 universities in China, namely, the Nine Schools Alliance (C9) and the University of Chinese Academy of Sciences, the Report found that 7 universities required physics majors to account for more than 50%. Among them, physics is required for all majors in China University of Science and Technology, and the proportions of Chinese Academy of Sciences, Harbin Institute of Technology, Xi ‘an Jiaotong University, Zhejiang University, Tsinghua University and Shanghai Jiaotong University are 76.92%, 74%, 72.72%, 72.2%, 60% and 51.16% respectively.

Like WeChat, the user information collected by QQ is also out of scope, but according to the Guidelines, if you refuse to provide relevant information, it will only affect the corresponding functions and will not affect the basic functions.

Tik Tok:

In the "Regulations", the basic function service of short video apps is "video search and play for no more than a certain period of time", and the basic function service can be used without personal information.

Tik Tok Privacy Policy points out that the information provided by users and obtained by automatic means includes account number, identity authentication, log information (click, follow, collect, search, browse and share), release information, address book, geographical location information and equipment information.

However, Tik Tok said, "Based on our cooperation with communication operators, when you use the" one-click login "function of Tik Tok, the operator will send us your mobile phone number with your express consent, so that we can provide you with fast login service. The mobile phone number belongs to personal sensitive information. If you refuse to provide it, you will not be able to register and log in to Tik Tok by "one-click login", but it will not affect your registration and login by other means, nor will it affect the normal use of other functions. "

In addition, Tik Tok said that in order to improve the uploading speed of audio and video, enrich the publishing function and optimize the experience, when users publish audio and video, Tik Tok will temporarily load the audio and video to the server before clicking "Publish" to confirm the uploading. However, users can turn it off in the settings.

To sum up, users’ device information, log information and Cookie are basically collected by default. After entering the App, there is no relevant button to choose to reject the "collected" device and log information; If you want to reject the "collected" Cookie, you need to turn off the relevant permissions in the browser, and you need the browser to support the relevant functions.

For example, in the Regulations, online audio-visual apps can use basic functional services without personal information. In iQiyi’s privacy policy, iQiyi claims that refusing to provide equipment information and log information may lead to the inability to use products and services.

It should be noted that the definition of whether device information, log information, etc. belong to personal information is still vague. Pinduoduo mentioned in his privacy policy that individual device information, log information, search keyword information and other information or data that cannot be directly linked with a specific individual are not personal information or personal sensitive information. However, according to the national standard "Information Security Technology Personal Information Security Specification" implemented in October last year, online records, common equipment information, etc. belong to personal information.

　　CCTV News:On July 12th, the State Council held a press conference. China National Intellectual Property Administration introduced that at present, the development of intellectual property rights in China is progressing steadily, the quality is improved, and the patent reserves in emerging technologies are enhanced.

　　At the press conference, Hu Wenhui, deputy director of China National Intellectual Property Administration, introduced that by the end of June this year, the effective number of invention patents in China was 3.906 million, up 17.5% year-on-year. There are 325,000 enterprises with effective invention patents in China, with 2.107 million effective invention patents, which is 4.5 percentage points higher than the national average growth rate.

　　Hu Wenhui introduced that by the end of June this year, the top three technical fields in China were computer technology, measurement and digital communication. The top three growth rates were information technology management methods, computer technology and medical technology, which increased by 78.5%, 32.3% and 27.1% respectively.

In today’s market, plug-in hybrid vehicles (PHEV) and automobiles (EREV) have become the focus of consumers’ attention. This paper will analyze the differences between the two models in detail, and discuss them from the aspects of cost performance, typical models, core competitiveness and shortcomings, and analyze them with real cases in order to provide valuable reference information for readers.

Basic principles and differences between (PHEV) and (EREV)

Plug-in hybrid vehicle (PHEV) has both traditional fuel and fuel, and can be driven in various modes, such as, pure fuel or so on. The car (EREV) is only equipped with an electric motor, and the battery is charged by the fuel engine to realize driving.

In terms of cost performance, the price of plug-in hybrid vehicle is relatively high because of its relatively complex power system and high cost. The car has a relatively simple power system and low cost, so the price is relatively low.

In terms of typical vehicle models, plug-in hybrid vehicles are represented by DM, PHEV, etc., and automobiles are represented by, etc.

The core competitiveness of plug-in hybrid vehicle lies in its flexible driving mode, which can be switched according to different scenarios, which can not only enjoy the driving experience, but also realize the fuel-driven endurance guarantee. However, its disadvantage is that the power system is complex and the maintenance cost is high.

The core competitiveness of a car lies in its driving experience, which has a high. However, its disadvantage is that the cruising range is limited by the battery power, and when the battery power is insufficient, the driving range will be affected.

Taking BYD Tang DM He as an example, the vehicle types are compared and analyzed;

1. Price: The price range of BYD Tang DM is 200,000-300,000 yuan, while that of Li ONE is 300,000-400,000 yuan. Plug-in hybrid cars have a slight advantage in price.

2. cruising range: BYD Tang DM has a cruising range of about 80-100 kilometers in the mode, and Li ONE has a cruising range of about 180 kilometers in the mode, so the car has more advantages in cruising range.

3. Power performance: BYD Tang DM can achieve strong power performance with the cooperation of fuel engine and motor. Li ONE, as a car, although not as good as plug-in hybrid car in power performance, can meet the daily driving needs.

Based on the above analysis, plug-in hybrid cars and cars have their own characteristics, and consumers can make choices according to their own needs. When buying a car, you can consider the car budget, cruising range, power performance and other factors, and combine the actual test drive experience to select the most suitable model for you.

(|||) (||)(||)ev is the first four-seat new energy vehicle under SAIC-GM. This model is mainly positioned as a commuter scooter, and can also be used for short-distance driving. Then when it comes to travel, you have to mention the cruising range of Wuling Hongguang. So what is the cruising range of this car? Let’s take a look at the detailed explanation of Pacific Auto.

The measured endurance is 150 kilometers.

At present, there are two models of the latest 2021 Wuling Hongguang MINI on sale, with a guide price of 376-436 thousand yuan and a cruising range of 120km and 170km. The main test is the 170km endurance version of Wuling Hongguang MINI, which runs on urban roads with normal driving habits. In the end, the cruising range of Wuling Hongguang MINI can reach 150km.

Excellent power system

The price of only about 40 thousand yuan can reach the battery life of 150km, which is very good, mainly thanks to the excellent power system of Wuling Hongguang MINI. In terms of power, the model is equipped with a permanent magnet synchronous motor with a total power of 20kw and a total torque of 85N.m, and is equipped with a 13.8kwh ternary lithium battery pack.

Security configuration

Wuling Hongguang MINI not only has excellent endurance and excellent power system, but also has rich safety configuration. In terms of safety, the new car is equipped with anti-lock braking, brake distribution system, main driver’s airbag, tire pressure monitoring, rear parking radar, rear image and uphill assist.

Through this description of the cruising range of Wuling Hongguang MINI, we can see that the measured cruising range of Wuling Hongguang MINI is very good.

The above is the related content of the measured cruising range of Wuling Hongguang MINI, which can reach 150km.

Replay it 4000 times and it won’t fall to the altar.

Recently, when the glory of the king was opened, "Yungong Xunyin" sounded in the opening animation, and the DNA of netizens in the whole network moved again.

This "National Game" with a cumulative income of over $10 billion in October completed a historic linkage with the 86th edition of "National TV Series" The Journey to the West. Since the project was announced, it has been a frequent visitor to Weibo Hot Search, and every time a new skin goes online, it will also become the focus of discussion.

"the glory of the king" and "Sun Walker" skin

Director Yang Jie died in 2017. At that time, it was generally reported that the TV series had been replayed more than 3,000 times. In the promotional video of the glory of the king, the number became 4,000. Forty years ago, Yang Jie took the The Journey to the West crew for six years, trekked more than 100,000 kilometers, walked through 26 provinces and cities in China, and achieved a legend of the times with only one camera.

In the behind-the-scenes tidbits, several masters were delighted to be able to return to the public’s field of vision by this trendy form of games. Li Shihong, a voice actor in the Monkey King, said: "Unexpectedly, everyone has not forgotten us."

At that moment, the barrage was neatly brushed: "I can’t forget it!"

Journey to the West, or a presumptuous guest usurps the host’s role?

Thirty-five years ago, the first eleven episodes of The Journey to the West were broadcast during the Spring Festival, which caused a sensation in Xian Yi and the whole country, setting a viewing myth of 89.4%. Over the past 35 years, it has filled children’s childhood in winter and summer vacations every year, and its influence has been incalculable because of thousands of replays.

Today’s headlines released a set of data in 2016. The "Top10" of The Journey to the West’s original works respectively correspond to the story of the monkey king, Monkey King Thrice Defeats the Skeleton Demon, the three-borrowed banana fan, and the girl country. Without exception, all of them are stories filmed by The Journey to the West in the 86th edition, while the equally wonderful chapters of the original works (the sequel to Journey to the West in 2000) did not enter the top ten.

That year was the Year of the Monkey in the Lunar New Year. In a nostalgic trend, the program "Monkey Play", in which six-year-old children cooperated with Aaron Kwok, caused public dissatisfaction because they missed the CCTV Spring Festival Evening. Even though six-year-old children clarified that they had never been invited by CCTV, "Six-year-old children went to the Spring Festival Evening" and "Six-year-old children’s programs were killed" became hot topics in Weibo. There was no "Six Learning" in that year, and only millions of people jointly called for the Spring Festival Evening to interpret their dreams for the audience.

Not only at home, the 86th edition of The Journey to the West was also famous overseas. It is the first batch of TV dramas exported by New China, which was first broadcast in Southeast Asian countries such as Myanmar, Vietnam and Thailand. An article in Reference News mentioned: "In Vietnam, it caused a situation of empty lanes. When the drama was broadcast, even thieves and policemen disappeared from the streets." The score of the play in IMDB is still 8.6, and there are many comments on YouTube, such as "Thanks for enriching my childhood".

However, high status will inevitably bear more scrutiny.When the number of viewers who have seen the 86th edition of The Journey to the West far exceeds the number of readers who have read The Journey to the West’s original works, and the Monkey King, a six-year-old child, is "genuine", the voice of "misinterpreting the original works" has never stopped.

In the 86th edition, The Journey to the West made many adaptations to the original, such as the girl country section in the original, in which the relationship between the Tang Priest and the king was distinct from the beginning, and the TV series added a lot of tender and lingering "affection" meaning, and the Tang Priest’s momentary temptation was widely circulated with the song "Daughter Love".

At the same time, this TV series also added a "beauty filter" to the four masters and apprentices in the original work. Pig Bajie was originally a black wild boar with a "black face, short hair, long beak and big ears", but in the play it became white, fat and lovely, and Tang Priest often showed cowardice, selfishness and other despicable human nature. More contradictions focus on the Monkey King. The appearance of a six-year-old boy can be summarized as "Monkey King", while the Monkey King in the original works is short and ugly.

The Paper’s "Shanghai Book Review" column once published an article saying that "A Chinese Odyssey is closer to the original work than the 86th edition of The Journey to the West", and People’s Literature Publishing House also published an article expressing that "Yang Jie’s version of The Journey to the West is not as close to the original work as Stephen Chow’s", and compared the films such as "Demonizing the Journey to the West" together, saying that "the Monkey King’s cuteness, courage and kindness are completely inconsistent with the cannibalism, ferocity and violence in the original work". As for whether the Monkey King is "cannibalistic", there have been debates in Zhihu and other communities.

In essence, the 86th edition of The Journey to the West is also the product of a specific era.Its adaptation purpose completely conforms to the interpretation of novels by mainstream literary circles at that time:Full of romantic fantasies, praising rebellious mythical heroes. The TV series also "eliminates the weeds and saves the seeds", amplifying these parts that are in line with the "original spirit".

Chinese people’s feelings about traveling to the west are, to a great extent, feelings about the 86-edition TV series. On the level of "popularizing famous works", it has obviously taken the lead, but it is undeniable that without this version of TV series, many viewers will not think of paying attention to the original work.

A camera, a journey to the west.

The 86th edition of The Journey to the West’s filming road is also an out-and-out "learning from the classics". Yang Jie wrote in his autobiography: In people’s eyes, people of our time may be "idiots".

In the original work, there are both Yaochi Wonderland and the eerie demon cave. In order to put the beautiful scenery of mountains and rivers and humanistic architecture into the play, Yang Jie conducted a 63-day national landscape picking. When we arrived in Zhangjiajie, which had not been developed into a scenic spot at that time and was named "Shangyong", the mud road was slippery in the rain, and the van that the group took almost fell from the corner into the cliff.

Yang Jie once recalled,"The hardest part is stunts, which is an era when I don’t know what stunts are."There is only one Sony 300P split camera and only one machine in the whole crew, which means that the lenses of different positions have to be compensated by the "stupid way" of stacking times.

In the past six years, Yang Jie’s husband, Wang Chongqiu, went to the porthole to take pictures of the blue sky and the sea of clouds every time he flew. Some of these precious materials should be used as separate shots, while others should be used as the background of the key image. There was no professional photographic rail car, so Wang Chongqiu borrowed a bicycle from the crowd to replace it. There was no elevator, so he used three pillars as a seesaw to build one. The scene of "Underwater Dragon Palace" was created by the fish tank blocking the camera.

Blue screen keying relies on an imported ADO special effects machine, but when it is actually used, the crew found that it only bought hardware and didn’t buy supporting software, so it could not achieve three-dimensional effect. The software costs 50,000 dollars, far exceeding the budget, so many characters in special effects scenes in this version of The Journey to the West are "paper people".

Only the problem of funds can’t be overcome by hard work or clever thinking.When the 14th episode of "Hong Haier War" was filmed, the crew was plunged into economic crisis. The leader in charge said to Yang Jie, "Let’s make an ending." Yang Jie refused with the determination of "success or death" and filmed while raising money. The fundraising didn’t go well. In the end, Li Hongchang, the deputy director of production (who plays the role of black fox essence and centipede essence, etc.), raised 3 million yuan from the Eleventh Engineering Bureau of the Ministry of Railways, but in the end, it was reduced by 5 episodes and only 25 episodes were filmed.

Yang Jie’s salary for filming an episode by himself was 90 yuan. "Monkeys and Pig were 80, and Friar Sand was 60, so there was only a little reward." In Yang Jie’s memory, at that time, everyone didn’t talk about remuneration, regardless of time, and there was a record of working continuously for 23 hours. When traveling back and forth in more than 20 cities across the country, several wagons have to be moved by themselves, including four masters and apprentices.

The crew has a 30-cent night meal fee, which needs to be received after 11 pm. "When I eat at night, I said that I should add two bottles of beer to each table, and they all cheered. People at that time were very cute. "

In 2014, Han Han spent 100,000 yuan on The Journey to the West’s episode Daughter’s Love. It was the first time that Xu Jingqing and Yang Jie knew that there were still copyright fees, and they each took 30,000 yuan.Yang Jie said to Xu Jingqing, "Old Xu, this is the first time I have got such a high fee and so much money."

"Everyone is rushing to’ shoot a classic goal’." Xun Hao, deputy director, said, "No one will shoot TV series like this anymore."

A "sealed" westward journey

In this way, the 86th edition of The Journey to the West stands high on the historical coordinates, and the latecomers look up and approach, but no one can climb it.

The original challenger is itself. In 1998, Yang Jie applied to CCTV, and someone in the former crew had passed away. Otherwise, the five episodes that were cut off would be permanently lost. Yang Weiguang, then the director, agreed to shoot, and suggested that it was not only possible to shoot five episodes, so the script of Journey to the West was expanded to 15 episodes.

Restart the first episode of filming "Love Broken Black River", and choose Miyun Reservoir on the outskirts of Beijing. CCTV provided several mobile camera positions, and transferred two large cranes and a sprinkler. Compared with the hardships of filming version 86, the capital and technical conditions of the crew have been significantly improved. Yang Weiguang attached great importance to the sequel, and specially invited Cao Rong, the best action director of the Golden Horse Award in 1997, as the martial arts finger of this drama. In this episode, Cao Rong made a guest appearance in Prince Muang, the son of the West Sea Dragon King, which planted a seed for another controversial TV series in the future.

However, after the whole drama Journey to the West was broadcast during the Spring Festival in 2000, the response was mediocre, far from the grand occasion of that year. Yang Jie herself admits that the make-up is far from as simple as she imagined, and the final rendering effect is "far worse than the 86 version".

The makeup of the characters in Journey to the West is not exquisite enough and is also criticized.

There are different opinions on the reasons. Many fans have compared the two editions, pointing out that the level of Journey to the West has declined in aspects such as role makeup and lens scheduling. Even the theme song with high popularity, "Just captured several demons and surrendered several demons", is lower in artistic conception than the 86 edition, "Don’t boast that all monsters are scared, don’t mention dangerous mountains and evil waters."

Some media once asked Yang Jie, "Is it because the appreciation taste of the people has changed after 17 years, and the director’s thinking still stays in the past?" Yang Jie only said that "the story is no worse than before, but the character has not developed."

In the past 35 years, there have been two TV series filmed by The Journey to the West Quanben in the Mainland. In 2010, 52 episodes of The Journey to the West Douban filmed by Zhejiang TV Station scored only 5.7, which was not very meaningful. In 2012, Zhang Jizhong’s 60 episodes of "new journey to the west" took the road of "restoring the original work", but it was still not recognized by the audience because it wanted to make it too comprehensive and could not avoid the director’s personal "bootleg".Once compared, the 86 th edition was further pushed to the altar.

"Journey to the West" is an exception. In 1999, a businessman in Xi ‘an took a loan of 15 million yuan and a 20,000-word script to ask him to be a director. The original six-year-old boy temporarily refused to perform, so Cao Rong had to take the lead and said to the makeup artist at two o’clock in the morning, "Why don’t you let me try?" Cao Rong kept his eyes closed for fear of being laughed at during makeup, and only after taking the makeup photo did he find "OK", and a facial paralysis version of "Fight over Buddha" was born.

In addition to being unable to express his face because of makeup, Cao Rong knew that if he followed the same example, "No performance can beat a six-year-old child", he decided on the performance strategy of "three-point monkey, seven-point man", which was more in line with the steady changes after the Monkey King became a Buddha.

After the first edition of the 20,000-word story was changed into a script, it couldn’t support 30 groups at all, and it didn’t last long enough after the whole drama was filmed. However, the number of episodes is the boss’s rigid requirement. Cao Rong cut the action drama for half a year, "Try to slow down here, speed up there, or repeat some places", and was forced to create a "ancestor of ghosts and animals".

In Cao Rong’s memory, when The Journey to the West was broadcast, some people liked to jump on the street, while others scolded them. No one expected that it would become popular again because of "facial paralysis" and "ghost animals" several years later. At the end of 2019, Cao Rong moved to bilibili and began to re-edit "Journey to the West". A large number of viewers salvaged this TV series from their childhood memories, recalling that its plot was actually quite wonderful besides the stunt, and even many viewers really thought it was the story experienced by four apprentices after the westward journey.

However, the filming process and the red-hot process of Journey to the West are full of accidents, which can be recognized by the audience because its story frame has been divorced from The Journey to the West’s ontology, not to mention the impact on the 86 TV series.

Classic works like The Journey to the West,The audience can actually accept being unconventional without destroying the essence.The Biography of Journey to the West is a microcosm, and the movie A Chinese Odyssey, the online biography of Wukong, the animation The Return of the Great Sage, and the game Black Myth: Wukong have their own fans.But at the same time, once Zhu Yu is in the front, everyone’s tolerance threshold for "remake and destroy classics" has always been extremely low.With the passage of time, the 86th edition of The Journey to the West, which has been bearing the memory of several generations, has been almost stamped with an untouchable historical seal.

The Story of Wukong took a subversive route earlier in the Mainland.

Objectively speaking, the TV series 35 years ago will not be perfect, and there are also basic problems such as unstable supporting actors and rough special effects technology. In Yang Jie’s words, "everyone forgave it."

The 86th edition of The Journey to the West is a myth created in the era of "concentrating on doing great things". After 35 years of reinforcement, it is even more indestructible. Yang Jie once said that some works will surpass her The Journey to the West, but it is only a matter of time.

In a later interview, she added a note to this sentence: "But I don’t know if it goes on like this today."

The worst Jin Yong drama is always the next one.

Children of the jstars: When the double-speed button is pressed on the family drama.

CCTV News:The Guangdong Provincial Health and Health Commission reported today (June 1) that there were 11 new confirmed cases in Guangdong on May 31, of which 1 case was diagnosed as asymptomatic infection, all of which were reported in Guangzhou. Two new cases of asymptomatic local infection were reported in Guangzhou. Since yesterday, Guangzhou has adjusted the pace of vaccination, first arranging group appointments and collective vaccinations for key industries and key groups in an orderly manner, suspending individual appointments and social vaccination for COVID-19 vaccines.

Dawn, Vice Mayor of Guangzhou:Recently, the general public’s willingness to vaccinate is high, and the inoculation points are overcrowded. In order to reduce the possible risk of Covid-19 infection, we temporarily stop social vaccination. Please rest assured! We will restart personal appointment vaccination and on-site vaccination as soon as possible according to the prevention and control situation.

The first task: strengthen the flow and trace the source and cut off the communication chain.

Li Ming, deputy mayor of Guangzhou, said that the virus gene sequencing of all the infected people in this epidemic is highly homologous, and all the infected people are mutant strains found in India. This virus has the characteristics of short incubation period, fast transmission speed and high virus load. Therefore, Guangzhou strengthened community prevention and control, and suspended social vaccination of COVID-19 vaccine. But will this affect the progress of establishing an immune barrier? Let’s listen to the experts.

Wu Hao, expert of Guangdong Working Group of the State Council Joint Prevention and Control Mechanism Comprehensive Group:Why stop the vaccination of some vaccines and concentrate on nucleic acid detection and screening is to strive for early detection. Vaccination is to produce antibodies, which may take some time. For the prevention and control of this epidemic, the role of vaccines is not particularly great. Generally speaking, the epidemic can be controlled within 28 days, that is, within two incubation periods. This is the first point. Second, generally speaking, vaccination in risk areas, especially social vaccination, may lead to the gathering of people and the possibility of unnecessary cross-infection. Therefore, the suspension of vaccination in some areas is also to avoid crowd gathering. Third, the primary task at present is to prevent and control the epidemic situation and cut off the community transmission chain. It is scientific to concentrate all efforts to control the source of infection and cut off the transmission route, and to suspend the adjustment of vaccination work.

As we all know, Guangzhou is a first-tier city, and we can’t completely stop the city, but for the "core area" of the epidemic, it is required to stop the area and reduce the possibility of cross-infection. Therefore, the core area and sub-core area are adopted to find the most appropriate balance between life production and epidemic prevention and control.

　　On April 17th, the reporter learned from the FAST Operation and Development Center of the National Astronomical Observatory that more than 900 new pulsars have been discovered by the 500-meter spherical radio telescope (FAST) known as the "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)".

　　Produce a series of world-class achievements in the fields of the origin of fast radio bursts and gravitational wave detection; Independent research and development of receiver core components is expected to go abroad; FAST core array construction is ready to go … …

　　Staring at the starry sky, I kept walking. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" is constantly providing China wisdom to the world astronomy and China technology to the global engineering community.

　　Frequent achievements

　　"Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" is a well-known national weapon. In order to "produce early results, produce more results, produce good results and produce great results", China scientists constantly "challenge the limits of cognition and technology" and polish their profound "eyes" with "Creation by China".

On April 17th, the reporter got news from the FAST Operation and Development Center of the National Astronomical Observatory of the Chinese Academy of Sciences that the number of new pulsars discovered by the 500-meter spherical radio telescope (FAST), known as the "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)", exceeded 900. Xinhua News Agency issued Liu Xu Lu Yuhan’s establishment

　　Up to now, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has discovered more than 900 new pulsars, including at least 170 millisecond pulsars, 120 binary pulsars and 80 faint occasional pulsars.

　　"We are expanding the cognitive limits of human beings to the universe." Han Jinlin, head of the galactic plane Pulsar Survey Project of the National Astronomical Observatory, said. In the 50 years from the discovery of the first pulsar by humans to the discovery of the first pulsar by FAST, less than 3,000 pulsars have been discovered in the world.

　　On October 10th, 2017, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) announced the discovery of six new pulsars, achieving a "zero breakthrough". This is the first time that China has discovered pulsars with its own independently developed radio telescope.

　　At present, more than 900 new pulsars have been discovered by Five-hundred-meter Aperture Spherical Radio Telescope (FAST), which is more than three times the total number of pulsars discovered by other telescopes at the same time in the world.

　　Among them, compared with the normal pulsars, the radiation flux density of 80 faint occasional pulsars is one order of magnitude lower, and the lowest one has reached the submicrocentric order.

　　In Han Jinlin’s view, the study of these accidental pulsars is of great significance for understanding how many dense neutron star wrecks are formed after the death of stars in the Milky Way and revealing the unknown physical process of pulse radiation.

　　Han Jinlin told reporters that if searching for pulsars is compared to picking fruits, all the pulsars discovered before are close to the ground and easy to "pick", while the more than 900 new pulsars discovered by Five-hundred-meter Aperture Spherical Radio Telescope (FAST) are farther away or more difficult to pick.

　　Because each pulsar has its own special pulse and stable rotation frequency, they are equivalent to the "lighthouse" with unique signal marks in the universe. If the Interstellar can be realized in the future, these pulsars will provide "navigation" for human beings to travel in the vast universe.

　　"We accurately measure the coordinates of pulsars in space, and monitor the phases and corresponding positional relationships of multiple pulsar signals during the journey, so that humans will not get lost in interstellar travel." Han Jinlin said.

　　It is the first time to observe the "pulse" of black hole in radio band, detect the key evidence of the existence of nanohertz gravitational wave, and detect and construct the world’s largest neutral hydrogen galaxy sample … … In recent years, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has made China contributions to exploring the mysteries of the universe.

　　In the face of the unknown and the future, human destiny is shared. From the moment it was born, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" shouldered the mission.

　　Sun Chun, the measurement and control engineer of Five-hundred-meter Aperture Spherical Radio Telescope (FAST), introduced that since it was officially opened to the global scientific community on March 31st, 2021, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has helped research teams from 15 countries including the United States, the Netherlands and Australia to carry out observation for nearly 900 hours, covering many fields such as scientific target drift scanning survey, neutral hydrogen galaxy survey, galaxy polarization survey, pulsar time measurement, and rapid radio burst observation.

　　In the foreseeable future, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" will bring more new perspectives for the international astronomical community to continue to explore the universe and try to find the unknown, and make greater contributions to leading mankind to break through the new field of cognition.

　　Innovation is not limited.

　　"I thought it would be revised seven or eight times, but I didn’t expect the performance of the first edition to reach the world advanced level." Chai Xiaoming, a senior engineer at the National Astronomical Observatory of the Chinese Academy of Sciences, introduced to the reporter a low-noise amplifier with a silver-plated shell and only the size of an organ. It was hard to hide his excitement in his speech.

　　Low noise amplifier is the core component of Five-hundred-meter Aperture Spherical Radio Telescope (FAST) receiver, which was imported before.

　　In order to solve the problem of "stuck neck" and master the key technology in their own hands, Chai Xiaoming’s team spent nearly two years independently developing this high-performance domestic low-noise amplifier.

　　Once the prototype was launched, it attracted the attention of the international astronomical community. The BINGO project in Brazil first proposed the willingness to cooperate in bulk purchase to the FAST Operation and Development Center.

　　As the largest and most sensitive single-aperture spherical radio telescope in the world, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has stimulated many special technical requirements, which requires China scientists to give full play to their subjective initiative and creativity, and to optimize and upgrade by constantly "challenging the cognitive and technical limits" and constantly "discovering and solving problems".

　　There is no shortcut to innovation, only dare to climb.

　　"No one told you what to do, and no one was sure that his own method would work." Jiang Peng, executive deputy director and chief engineer of FAST Operation and Development Center, said that the difficult research of "trial and error, failure and courage" runs through almost every link of FAST construction stage.

　　In order to solve the problem of cable fatigue, Jiang Peng led a group of young people through nearly 100 failures and successfully supported the "retina" of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)".

　　"Eye of the Sky" asks the sky, and there is no end. Jiang Peng said frankly that if FAST is only regarded as a telescope and a monitoring device, it has reached the standard now. However, to maintain the leading position of FAST in the world, our innovation cannot stop, and we will do our best to make FAST more stable and efficient.

　　At present, the annual observation time of FAST is stable at about 5,300 hours, which plays an important supporting role in continuously outputting scientific research results.

　　Compete for the future

　　Explore the sky and decipher the stars. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has never stopped innovating.

　　"Astronomy is extremely romantic, because it studies the sea of stars of human beings. Astronomy is also extremely cruel, because international competition is extremely fierce, and once it is relaxed, it will lose its leading position. " Jiang Peng said.

　　Looking around the world, many radio telescope arrays, such as SKA, are under construction.

　　"Once these telescopes are put into operation, ‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Will face enormous challenges. " Jiang Peng said, "If we relax a little, China astronomers may ‘ Lost ’ The forefront of the radio band field of vision. "

　　The reporter recently walked into the core area of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" and saw on a hill less than 3 kilometers away from "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" that the excavator was working intensively, and the original jagged hill top with miscellaneous trees had been leveled and compacted.

　　"We plan to use the excellent electromagnetic wave environment within 5 kilometers around FAST in the next five years to build 20 to 30 fully movable radio telescopes with a diameter of 40 meters, and form a comprehensive aperture array with FAST, that is, the FAST core array." Jiang Peng told reporters that a 40-meter-class fully movable radio telescope will be built on the working hill within this year.

　　"By ‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Observing the universe is like using ‘ Thick-headed pencil ’ If the core array is completed and put into use, it is equivalent to using high-resolution ‘ Digital camera ’ Shoot the distant stars. " Jiang Peng introduced that once the core array is completed, it will greatly improve the vision of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" and let "‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Not only can you see far, but you can also see clearly. "

　　【Pacific auto network tire channel】 This issue of Xiaobian will introduce you to sports tires. The biggest feature of sports tires is high performance and excellent handling performance. There are many sports tires on the market, and the more choices car owners face when changing tires, the more tangled they tend to be. The average car owner will buy according to several aspects: brand, price, original tires and friends’ introduction, etc. These are good methods, but the most important thing is that the car mainly knows the tires and knows what kind of tires to choose. Therefore, Xiaobian will introduce the mainstream representative sports tires on the market, so that everyone can understand them first and then make a choice.　　

　 　In order to facilitate your reading, please first understand the following parameters:

　　Hub diameterAlso called rim diameter, it refers to the size of the tire suitable for mounting on the hub.load index, refers to the maximum upper limit load of the tire.speed, refers to the maximum upper limit speed of the tire.figure, refers to the structure of tread grain, mainly including symmetry, asymmetry and single direction.abrasionindex, is the main measure of tire tread wear performance and service life of the logo, the higher the score, the more wear-resistant.Traction index, which is a measure of the adhesion between tires and the ground, is divided into four levels: AA, A, B and C, with AA being the highest.Heat generation index, is the ability of tire to resist heat generation, which is related to the high-speed performance of tire. It is divided into three levels: A, B and C, with A being the best. (Please click for more details.This > > >)

　　　 What is a sports tire? Sports Performance The tread groove of the tire is relatively wide and the tread blocks are relatively large, in order to have good drainage performance and strong grip on the ground, but this kind of tire has obvious shortcomings, such as loud noise and poor comfort. Sports tires and comfortable tires are two extremes. To pursue the sports performance of tires, we must give up the comfort performance, and vice versa. However, there are also some tires that can achieve comfortable and well-balanced movement, such as Pirelli’s P Zero Rosso and Goodyear Sanneng.

You can click the following link to jump directly to the tire brand information you want to know:

Compact, medium-sized and medium-sized cars suitable for 16-20-inch wheels: 800-2060 yuan.

　　　　Goodyear Eagle F1 Directional 5 is a tire with single tread pattern. The tread integrates three technologies: central annular rib, fully enclosed shoulder and polymer formula. This is Goodyear’s SportGrip technology. The central annular rib improves the steering response ability; Shoulders on both sides are fully enclosed to reduce the noise generated by the tire during driving; The optimized tire carcass section increases the ground contact area, and finally improves the grip. This design not only improves the grip, but also reduces the noise, killing two birds with one stone.

　　According to the test, D5′ s lateral grip is stronger than D3′ s, and its handling response is better when changing lines, and there will be no tire ringing or slipping for a long time when hitting the direction at a fast and large angle. This is mainly due to the design of the four main drainage grooves of the tread (to improve the drainage capacity) and the central annular rib (to improve the response ability of line change).

　　　　 D5′ s wear index is 300, which is not too high or too low. For an active high-performance sports tire, it’s ok. One thing we should pay attention to, D5 is a tire with a single guide pattern. What does this mean? When installing, it is necessary to clearly distinguish the direction from the inside and outside, and it is also very troublesome to choose the spare tire. It can only be installed on one side, and another time, we must find another way. Its wheels have five specifications of 16-20 inches, which are mainly suitable for compact, medium-sized and medium-sized cars.
