Face the incurable disease of the century

It has been more than 20 years since the first AIDS report was published in June 1981. Although people’s understanding of AIDS is increasing day by day, they have not been able to find effective prevention and treatment drugs. As a terminal illness in the 20th century, AIDS is still a lingering shadow on the human head, with more than 40 million people infected with HIV worldwide. In the new century, conquering AIDS is one of the most urgent tasks in the world.

AIDS is a transliteration of the English acronym "AIDS" for "acquired immunodeficiency syndrome". HIV is a lifelong infection, which destroys people’s immune system and makes people lose their ability to resist various diseases.

In 1983, French scholar L. Montagni Ai isolated a related virus from the lymph nodes of patients, which was called lymphadenopathy-associated virus. In the same year, American scholar Gallo isolated the same virus from patients. It was later proved that the above virus was the pathogen of AIDS. In 1986, the International Committee on Virus Classification suggested that the new virus be named human immunodeficiency virus (HIV). HIV is a retrovirus, with a single strand RNA at the core and an envelope outside. HIV is sensitive to heat and can be inactivated in 30 minutes at 56 degrees Celsius.

At present, anti-virus drugs are mainly used in the clinical treatment of AIDS. Nucleoside drugs were first used in 1987. In 1994, a protease inhibitor was introduced. After 4 to 5 years’ research, it has been gradually introduced to the clinic. In 1995, Professor He Dayi, a Chinese-American, invented the famous "cocktail therapy", in which protease inhibitors were mixed with other antiviral drugs, and the drugs were given when HIV just invaded the human body, so as to prevent the virus from damaging the human immune system before the onset of the disease. Although it can’t achieve the goal of eradicating AIDS, this therapy has been able to effectively control the development of AIDS patients.

In order to defeat AIDS, the international community has made great efforts. On January 1, 1996, the Joint United Nations Programme on AIDS was formally established in Geneva, sponsored by six United Nations agencies. Its main task is to lead and widely support activities aimed at preventing the spread of AIDS, make more effective use of the resources of the United Nations system, reduce the vulnerability and susceptibility of individuals, communities and special groups to AIDS, and reduce the harm caused by the AIDS epidemic. China is one of the earliest members of the Planning and Coordination Office, the highest administrative body of UNAIDS, and the first developing country to donate to the organization. In order to exchange experiences and achievements in time, formulate strategies and coordinate work, the International AIDS Society has organized an annual "International AIDS Conference" since 1985, and the number of delegates in recent sessions has reached more than 10,000.

At present, the number of HIV-infected people in developed countries is stabilizing or beginning to decline, while the number of infected people in developing countries is growing rapidly. According to statistics, 95% of AIDS patients in the world live in developing countries.

Chu Chengcheng：＂From the students, to the students＂

The "introspection teacher" on the podium

　　 Chu Chengcheng has won many awards at the national, provincial and school levels in various teaching competitions. Although she is honored, when talking about the feeling of winning the prize, she said frankly: "The initial intention of participating in the competition is not to win the prize, but through the platform of the competition, I can better reflect on how to make the geological engineering courses I teach rigorous enough, more vivid and easier for students to accept." After participating in so many competitions, Chu Chengcheng deeply realized that kung fu must be spent in peacetime. As the saying goes, "One minute on stage and ten years off stage", only by doing a good job in usual teaching and accumulating enough materials can the results come naturally. After each competition, Chu Chengcheng should reflect on himself and then sum up his own shortcomings, so that he can perform better in the next competition and future classroom teaching. Yang Yongjie, from Class 18-2 majoring in geological engineering, said: "Teacher Chu Chengcheng often gives us some examples in class to help us understand our professional knowledge, and never makes us feel boring. For example, she will introduce the foundation settlement problem to be taught from the leaning tower of Pisa, and so on. Moreover, the feeling of attending her class is that both sides are making continuous progress, and our understanding of the knowledge points to be learned is more profound. " As Chu Chengcheng himself said: "I still remember what an old teacher at school said at a meeting when I first started working, that is,’ Being a teacher is a conscientious job’. No matter how busy I am, I have to prepare lessons in a down-to-earth manner, teach seriously, and often reflect on myself.Can teaching be better today? Is it possible to use other examples in class? Easier for students to understand? ….. I believe everything comes to him who waits. Chu Chengcheng mentioned to the author what her doctoral supervisor said when she graduated: It is not easy for a young teacher to stand firm on the platform. After work, Chu Chengcheng deeply understood this sentence. In order to "stand on the platform", she has made a lot of efforts and accumulated experience. "In fact, as a teacher, I not only need to reflect on my teaching work every day, but also be a teacher and set an example for students to learn and live."

"Teachers and Friends" in Students’ Eyes

　　 Chu Chengcheng was funded by the National Scholarship Fund Committee and went to the School of Computer and Civil Engineering of Pacific University for a one-year exchange visit. Later, the school set up a bilingual teaching and training course. After comprehensively evaluating his ability level, Chu Chengcheng decisively signed up and obtained the teaching qualification. In 2018, Chu Chengcheng successfully completed the teaching task of "Modern environmental geology" in English for foreign students majoring in geological engineering, which showed her excellent teaching strength. In the face of foreign students in foreign countries, Chu Chengcheng put himself in their shoes. "I have had experience of studying abroad myself, and I can understand the hardships of studying abroad alone, so I often communicate with them while giving good classes to further understand what they think. For example, we will discuss the festivals and cultures of our respective countries together. In the friendship, I try my best to make them learn happily. " In fact, not only for international students, but also when teaching geological courses, Chu Chengcheng pays great attention to students’ listening experience. "I have been studying geological engineering for ten years, and my status has changed from a student to a teacher soon, so I often think that if I were a student, I would like teachers to teach. Now, I often communicate with my students, pay attention to collecting feedback from my classmates, and resolutely don’t let my courses become boring. " At the same time, in order to better promote the growth of students, Chu Chengcheng also participated in guiding undergraduates to participate in innovative and entrepreneurial projects and appealed to students.Make good use of the platform provided by the school and never read dead books. Hu Kailan of Class 18-2 majoring in geological engineering praised: "Sister Chu’s lectures are full of’ dry goods’, and we can feel that she has made a lot of preparations for this class during class. Usually, she will remind us what to prepare for the next class in the "Learning Pass", and she will take us to practice with a separate class before the exam for the professional calculation problem we are most worried about. She also gets along well with us and will communicate with us about postgraduate entrance examination, employment and other issues. Everyone likes her best because she always helps us solve many doubts from our perspective. " Although he is responsible for teaching seven specialized courses, Chu Chengcheng has always been able to experience the classroom from the students’ point of view so as to improve the teaching and keep exploring. He not only tries to enlighten the students with professional knowledge in the classroom, but also keeps up with the characteristics of the students and constantly optimizes the curriculum design.

"Respondents" in Life Examination

　　　When Chu Chengcheng talked about her study experience, she shared with the author the "busyness" of her college life. She talked about that she had been the president of the college student union during her college years and devoted herself to serving every student around her. She always regarded learning as the top priority in her student career, and her academic performance was always among the best in her major. In the end, the average score of all courses exceeded 90, and she was successfully exempted from China University of Mining and Technology. "Life is a comprehensive exam", "Time is like water in a sponge, you can squeeze it" and "Bite your teeth, hold on, and there is a vast sky behind you". These are her attitudes and determination when she encounters difficulties. She hopes that every student can face them firmly and calmly when they encounter difficulties. She also shared with the author her study methods in college, such as "To improve the pattern of learning English, we can start with IELTS", "Review the advanced mathematics one month before the exam, and review it for at least three rounds", "Different courses can adopt different review methods" and so on. Chu Chengcheng handled his work and family life in an orderly way, and used his love to help him become more involved in the teaching process. In Chu Chengcheng’s "life test", she always faced it with a positive attitude and tried to win "high marks", and the source of each point was the obstacles she overcame in her teaching and educating career.

　　 Take root in the platform, stand firm on the platform, come from the students and then return to the students. Chu Chengcheng, a young teacher, always thinks from the students’ point of view, preaching and teaching for the students, and at the same time constantly challenging himself, improving his teaching hard power and growing and progressing with the students. During the teaching days, she constantly showed her youthful demeanor, tempered her teaching skills, and helped every student to achieve something with her own efforts.

China console game appeared at the Tokyo Game Show in 2019.

People’s Daily Online, Tokyo, September 16 (Reporter Liu Junguo) The 2019 Tokyo Game Show in Japan was held from September 12 to 15 at the Muzhang International Convention and Exhibition Center. Hardcore Mecha, a console game exhibited by Rocket Boxing Studio in Beijing, China, attracted the attention of many participants.

Although Rocket Boxing Studio developed a demo in 2016, it was not officially released until June 27 this year. The final Hard-core Mecha consists of multiplayer mode and single-player story mode, which includes mechs with different functions, rich weapons and equipment dressing, ultra-hard sense of attack and high-precision animation performance. All fighting actions and shooting actions are manually operated by players, and everyone can play their own unique combination of fighting skills.

After the official release of "Hardcore Mecha", it ranked first in online store sales in PlayStation Japan for two weeks in a row, and kept the top three positions in online store sales in PlayStation Japan for one month. In the past two months, it won the most popular content in online store in PlayStation Japan, and gained a lot of discussions from players on social networks. In addition, Famitong, a veteran authoritative game media in Japan, scored 33 points (out of 40 points) for Hardcore Mecha, and IGN Japan Station, a famous American game media, also gave a high evaluation of 8.8 points (out of 10 points).

Mu Fei, the head of Rocket Boxing Studio, said that many members of the team are not professional game developers, because they really like games and work side by side and study hard. The whole team insists that all contents are completed within the team, whether it is the game itself or the game content, art animation, story plot, or even music sound effects, which are all original works of the team.

Analysts here pointed out that the success of Hardcore Mecha in Japan, where robot-themed games such as Gundam, Robot Wars and Transformers are prevalent, is due to the fact that the team is not imitating overseas robot action games, but has added its own recognizable original content, industry-leading technology and distinctive bold expression. It is worth mentioning that the publisher of Hardcore Mecha in Japan is a well-known Japanese action game that has developed well-known 2D fighting games such as Guilt Equipment. (End)

After 30 years with Shanghainese, why should this famous department store be rebuilt？ Insiders said

The Xujiahui business district in Shanghai has been frequently searched recently. First, the Pacific Department Store, which has been with Shanghainese for 30 years, ended.

Then the "oldest shopping mall" Shanghai 600 is about to be upgraded.

Now, another commercial landmark in Xujiahui business circle-Xuhui flagship store of Oriental Commercial Building has to be updated and rebuilt!

It was once a landmark and witnessed the 30-year development of Xujiahui business circle.

Located at No.8 Caoxi North Road, Xuhui District, Shanghai, Xuhui Store, the Oriental Commercial Building, is the first large-scale Sino-foreign joint venture retail business enterprise in Shanghai, which was established in 1992. It has five floors above ground and one underground floor, with a business area of 26,000 square meters. It is a joint venture between Hong Kong and Shanghai and opened to the public in January 1993.

Since the 1990s, with the construction of Shanghai Metro Line 1, Xujiahui business circle has gradually emerged as a series of commercial landmarks, such as Pacific Department Store, Oriental Department Store, Ganghui Plaza, Huijin Department Store and Mira City.

After experiencing the "dislocation competition" among the three major department stores (600, Pacific and Oriental Department Stores) and the "dislocation competition" between the format of department stores and shopping centers between the three major department stores and Ganghui Plaza, Xujiahui business district has become more and more famous and has become one of the top ten municipal commercial centers in Shanghai and a representative of the transformation of Shanghai’s business from "strip" to "circle".

Oriental Commercial Building has also left a heavy mark in the development history of local businesses in Shanghai.

Thirty years ago, the Oriental Commercial Building took the lead in positioning itself as a "high-end department store": it was the first one to put a piano in the mall, and you could hear the "tinkling" piano sound without entering the gate; In the shopping mall, the chairs for salespeople to sit down were removed for the first time, and all salespeople (except some special positions) received customers in a standing posture, which was also the first in Shanghai retail industry. From the Logo of "courtesy in the East" and the standard of "full service" to the cashier wallet similar to the cashier at the front desk of a five-star hotel, it has become a "crab eater" in Shanghai department store industry …

Many Shanghai residents have deep feelings for the Oriental Commercial Building.

However, some consumers pointed out that the flagship store in Xujiahui, the Oriental Commercial Building, has been in business for many years, with outdated facilities and fewer customers than before.

Shanghai Xuhui District and Bailian Group will write a new chapter of comprehensive and deepening cooperation. After this renovation and reconstruction, the Oriental Commercial Building will be divided into two parts: business and office. Among them, the commercial part is defined as "Contemporary Oriental Art Theme Experience Center", which blends retail, art, culture and lifestyle, and brings consumers a new experience of space commerce from the dimensions of creative architectural design, artistic space creation and commercial operation presentation. The office building is defined as "the cover of Xuhui business with the integration of literature and business and multiple vitality" to create a world-class business center with high profile, high quality and high service.

Why update and rebuild? The insiders said this.

Why should the flagship store of Xujiahui Oriental Commercial Building, which has a history of 30 years, be rebuilt? Some insiders pointed out that department stores are called "department stores", but compared with the massive goods in the online shopping era, the number of goods that a physical department store can sell is a drop in the ocean after all. In recent years, on the one hand, the department store format has been attacked by shopping centers and community convenience stores offline, on the other hand, it has to face the continuous diversion of e-commerce online, and the business decline has already appeared.

For example, the Pacific Department Store Huaihai Store, New Railway Station Store, Xujiahui Store, and Landmark Plaza on Nanjing East Road, which were once commercial landmarks in Shanghai, have all closed their stores. There were 11 stores in Paris at the peak of Shanghai in spring, and now there are 7 stores left, namely Wujiaochang Store, Huaihai Store, Pujian Store, Baoshan Store, Chengshan Store, Shaanxi Road Store and Tianshan Store. For traditional department stores, the transformation is imperative.

The dream of "chain department store" of Oriental Commercial Building has also been quietly reshaped. Today, Yangpu Store of Oriental Commercial Building has been changed to Youmai Life Plaza, focusing on the city outlet format; Huaihai Store of Oriental Commercial Building was changed to Huaihai 755, positioning itself as a "young and energetic living space"; Nandong Store of Oriental Commercial Building, the old building of Shiyidian Store and the east building of Shiyidian Store are combined into a large-scale commercial complex-the first department store commercial center.

Other department stores under Bailian Group are also accelerating the pace of transformation. For example, hualian department store on Nanjing East Road has been transformed into the first commercial building with the theme of "Secondary Element" in China-Bailian ZX; Huaihai Store, the first department store on Huaihai Middle Road, merged with Huating Isetan to form Bailian TX, the "Young Power Center" which focuses on fashion brands.

Not only the Oriental Commercial Building, but also some old commercial buildings in Xujiahui Business Circle are starting to be remodeled. For example, Meiluo City has been transformed into a "second-yuan" resort, and the sixth department store will be demolished and rebuilt according to the plan, and so on. The Xuhui District Government has previously stated that it is collecting the overall planning plan for the core area of the Big Xujiahui from the world, and plans to accelerate the construction of Xujiahui Center and the overall transformation of Pacific Department Store and Shanghai 600 plots by optimizing five rail transit, skybridge corridor and underground crossing system in the region.

In addition, Huilian Commercial Building, a food landmark that Shanghai people are familiar with, also has new movements: at present, the second and third floors of the shopping mall are being cleared, and the future will be transformed with food as the center. Huilian Commercial Building plans to enlarge and strengthen its own advantage plate. In the future, the whole building will continue the "gourmet gene" on the ground floor, focusing on food and catering business, and a series of catering brands will be introduced on the second and third floors to amplify the original business advantages.

The "food king" should also be updated and upgraded again

Founded in July 1991, Huilian Commercial Building is located at No.40 Tianyaoqiao Road, Shanghai, with a business area of 13,000 square meters. It is the first large-scale department store in Xuhui District. The first floor of the commercial building is known as the "shoulder handle" of Tianyaoqiao Road cuisine.

This is because most of the people who set up camp here are well-known time-honored brands, such as Xinghualou, Harbin Food Factory, Shanlin Cooked Food, Laodafang, Qiaojiazha ….. After a circle, consumers often "return home with full loads".

The 2nd and 3rd floors, which are mainly engaged in middle-aged and elderly clothing, bear the youthful memories of Shanghai aunts and uncles.

Nowadays, Huilian clothing store is about to usher in transformation and transformation, and the whole clothing clearance promotion is as low as 20%. The clothing areas on the second and third floors, which used to be slightly deserted, have suddenly exploded in popularity recently. It is reported that in mid-December, the mall will also launch a clearance gratitude feedback activity for clothes on the 2nd-3rd floors. Almost every counter has a super discount, and some counters also have "ultra-low price" of 158 yuan each from 69 yuan and 99 yuan.

The closing time of Huilian Commercial Building is expected after the Spring Festival. Due to the adjustment of commercial building format, some supporting equipment and facilities need to be rebuilt, which is expected to be implemented gradually after the Spring Festival.

In fact, this is not the first time that Huilian Commercial Building has been transformed and upgraded. In 2020, Huilian Food on the first floor of Huilian Commercial Building reopened after a month and a half of renovation, adding a popular Magnolia bakery and an imported food area, including coffee, steak, ham and seafood.

In 2021, Shenyan Restaurant, located on the 4th floor of Huilian Commercial Building, opened. This Shanghai local cuisine restaurant, which integrates working meals, friends’ dinners and banquets for guests, not only fills the blank of lunch demand of business people in Xujiahui business circle, but also provides new choices for family dinners for surrounding residents. This move is also a new attempt to carry out catering business at multiple levels in Huilian Commercial Building.

In the future, Huilian Commercial Building will continue the "gourmet gene" on the ground floor, focusing on food and catering management. Not only will the "gourmet paradise" on the first floor remain unchanged, but the second and third floors will also start selling delicious food. In combination with the upgrading of night economy in Xujiahui business district and the overall construction plan of Tianyaoqiao Road Leisure Catering Street, Huilian Commercial Building will mainly take the extension of the characteristics of Huilian food on the first floor as its core concept, introduce a considerable number of catering merchants, and improve the business categories of Huilian food; At the same time, expand the night economy and enrich the catering format and the supply of American food.

A detailed explanation of the mockingbird effect in the film market after the end of The Hunger Games

??Special feature of 1905 film network　Edward lorenz, an American meteorologist, once told us that a butterfly in the tropical rain forest of the Amazon River basin can cause a tornado in Texas two weeks later by flapping its wings occasionally. Similarly, a "mockingbird" on the big screen spread its wings to symbolize resistance. Four years later, it also brought some influence to the film market. With the release of the last film, the series of films will officially bid farewell to the audience. Looking back on the past four years, "Mockingbird" is not only a simple symbol of popular culture, but also a phenomenon worthy of discussion in Hollywood and even the global film market.

The "Mockingbird Effect" at the box office: the tricks of a series of films attract gold

The series of films "Hunger Games" is adapted from the novel of the same name by American writer suzanne collins, and tells a dystopian story of a teenager in the future world. The cruel hunger games devour the beautiful youth of the girl in the story. Up to now, The Hunger Games series has exceeded $2.3 billion (not included) in the global market, and the box office has become popular all the way.

Review the achievements of the first three films of The Hunger Games in these years. According to the data of Box Office Mojo, in 2012, the first Hunger Games earned $690 million at the global box office, and now it ranks 79th in the global box office list. In 2014, it achieved a global box office of 760 million US dollars, ranking 62nd in the global box office list.

At present, the best box office performance in this series is that the film grossed $161 million in the first weekend in North America, setting a record for the opening of 2D movies, and it also won the title of the 2013 North American box office champion. In the end, the second Hunger Games made a global box office of $870 million, surpassing movies such as,, and ranked 42nd in the global box office list.

Although it is a sci-fi Hollywood blockbuster, The Hunger Games is not so "big" in the blockbuster, especially the cost of the first one is only $78 million. For example, the films familiar to the audience, such as X Police: last stand,,, and so on, all cost more than 200 million US dollars (some of them are not as high as The Hunger Games at the box office), which shows that the return on investment of The Hunger Games is very impressive.

Although the investment of several Hunger Games is not too high, Lionsgate Film has risen rapidly with its beautiful marketing offensive and become a new force to compete with the "Big Six" in Hollywood. Lionsgate, which initially targeted the niche market with horror suspense movies, has now become an industry giant with a series of movies with billions of box office potential. And they continue to explore the value of the "super IP" of The Hunger Games. Lions Gate not only plans to turn The Hunger Games into a stage play full of science and technology, but also will build a theme park of The Hunger Games in the future, and try to attract money in different ways.

Actor of "Mockingbird Effect": Queen Cultivation of Flame Girl

Presumably, most fans who paid attention to jennifer lawrence before The Hunger Games did not expect that in a few years, she would become the darling of many fashion magazines and the spokesperson of several Dior series. After all, in everyone’s mind, her vivid image is the image of a mountain girl in bad karma as determined as in the movie. This is probably the most intuitive change that The Hunger Games has brought to jennifer lawrence — — From a young independent movie star to a glittering new Hollywood queen.

In 2008, jennifer lawrence won the Best Newcomer Award at the Venice International Film Festival, and nominated the Best Actress at the 83rd Academy Award the next year. Even so, at that time, she didn’t have a large number of fans and subsequent film appointments until she met The Hunger Games. Jennifer herself admitted that she was really lucky to meet such a film.

According to reports, there were more than 50 actresses who auditioned for the heroine of The Hunger Games. Jennifer played a scene in which Katniss volunteered to replace her sister to participate in the Hunger Games, which was unanimously recognized by the casting director and producer because she and the character had some unspeakable similarities. Excellent actors and works always achieve each other. Imagine if Jennifer had played a girl protected by vampires in a movie instead of Katniss, who was strong and courageous with a bow and arrow, she might not have achieved what she did today.

With the popularity of such a commercial film, jennifer lawrence stepped out of the original active independent film circle and had more room to display his talents. In 2011, she played the "Magic Woman" in the film, and in 2012, she won the 85th Academy Award for Best Actress, followed by the 71st Golden Globe Award for Best Supporting Actress in American Film. At present, she is working with Chris Pratt on Sony’s sci-fi masterpiece.

Today, jennifer lawrence is one of the most valuable actresses in Hollywood. Among the heroines who have won the popularity in teen movies, why did she become one of the "20 million dollar clubs" in Hollywood? This is no accident. In terms of movies, Jennifer is one of the few actors who have proved that she still has box office appeal outside the main series of movies, and it is not to mention action movies, drama movies or comedies. In terms of personal charm, Jennifer is not mediocre at all. Her careless and informal personality is loved by netizens, and she is also very opinionated when she meets something, and she can resolve the crisis with her wit. When she denounces the sexism of Hollywood pay, do you think that she is the mockingbird with natural leadership?

The Type of "Mockingbird Effect": The Rise of Juvenile Science Fiction Films

Before "The Hunger Games", the last teen movie series that was popular in America was. Both are adapted from best-selling books, both are teenagers’ themes, and the handsome men and beautiful women who are born after 1990 play the leading role. When many people walk into the cinema with the mentality of watching the dog blood story, they find that The Hunger Games presents an unexpected pattern. In terms of content, The Hunger Games doesn’t have the Marisol plot of teenagers’ movies, and at the same time, it doesn’t focus on the relationship between people and technology like ordinary science fiction movies. This interesting setting in the film, which happened in the future, is unexpected to many viewers, so it is full of attraction.

Although "The Hunger Games" brought not all favorable comments, but also a lot of spiteful voices, we have to admit that this new type of adding political metaphors to teenagers’ movies became popular rapidly and was widely copied. Since then, there have been more and more films of the same theme in the market, such as,, and so on. They all depict the story of the weak resisting power in the virtual world on the basis of teenagers’ movies.

However, not every work can have the good luck of The Hunger Games. Among dystopian movies, The Hunger Games is not the one that has never been seen before, but it is the one that is most in line with the aesthetics of teen pop today. Therefore, it can become an unsurpassed leader in similar movies, and even shailene woodley, the star of Divergent, has to be labeled as "the next big cousin" by the media. Now, the "Hunger Games" series of movies is over, but the popularity of teenagers’ sci-fi movies is still unabated. Many years ago, no one thought that teenagers’ sci-fi themes could occupy such a large share in Hollywood. As for the future, it depends on how the market digests.

Star Era ET is listed globally.

(Reporter Zhao Dandan) On May 9, Star Era ET was officially listed in Guangzhou. As a high-end new energy heavyweight model of Chery Group, Star Era ET extended range and pure electric double arrows were launched, and a total of eight versions were launched. At the press conference, Yin Tongyue, chairman of Chery Holding Group, said that with the launch of Xingjiyuan ET and other models, it is believed that Chery’s sales of new energy products will soon enter the top three in the industry.

Chery, which has always been known for its engine technology, entered the extended-range market for the first time and solved the user’s mileage anxiety with its long endurance. According to reports, the extended-range model of Star Era ET has a comprehensive battery life of 1518km when it is fully charged. From May 7th to 9th, Xingjiyuan ET held the first extreme endurance challenge for extended-range vehicles in the industry. The vehicle started from Wuhu with a full battery and a tank of oil, and finally arrived in Guangzhou via Zhanjiang, Guangdong Province. The final mileage reached 2141.4km, showing the hard-core strength of "reverse virtual standard".

The longest cruising range of Xingjiyuan ET pure electric vehicle is 760km. As the first mass-produced vehicle of Contemporary Amperex Technology Co., Limited Shenxing rechargeable battery in the world, Xingjiyuan ET can recharge 475km in 11.5 minutes, and the SOC (state of charge of battery, also known as residual capacity) changes from 20% to 80% in 24 minutes at the low temperature of minus 20℃.

Safety is the greatest luxury. In the aerial crash test conducted in Wuhu on May 6th, Star Age ET "freely fell" from a height of 31.9 meters, and the vehicle kept vertical collision and was in the power-on state. The front of the vehicle collided with the steel plate with a thickness of 4 cm on the ground 100%, and the instantaneous collision speed was as high as 90km/h, and the collision energy exceeded the industry standard by 3.24 times. The test results show that there is no obvious deformation in the passenger compartment structure of the vehicle, the doors can be opened, the airbags pop up normally, the battery has no leakage, no smoke and no fire, which demonstrates a new paradigm of high-end new energy security.

He Xu, deputy director of the Provincial Department of Justice, introduced that our province actively promoted the activities of "sending the law to the grassroots" such as anti-telecom network fraud into rural areas and communities, and mobilized more than 310,000 volunteers, more than 260,000 rule of law leaders and legal savvy people in the province to preach anti-fraud legal knowledge; Focus on the elderly groups to carry out the "case interpretation" activities to help the elderly understand fraud cases and modus operandi such as investing in "aged care services"; Focus on youth groups and organize more than 14,000 vice presidents of the rule of law in the province to give lectures on campus anti-fraud education; Make good use of new media communication methods, and publish more than 200 issues of anti-fraud typical cases and anti-fraud videos on platforms such as "Shandong Popularization of Law" and "Rule of Law in Shandong", which has formed a good publicity effect.

&emsp; &emsp; Wang Qinjie, Deputy Procurator-General of the Provincial Procuratorate, said that since the beginning of this year, the procuratorial organs in the province have insisted on cracking down strictly according to law, approved the arrest of 1,144 people for telecommunication network fraud crimes and the prosecution of 2,049 people, and approved the arrest of 1,022 people for helping information network criminal activities and the prosecution of 9,679 people. The ringleaders of fraud groups and other key attackers have put forward sentencing suggestions according to law, which has formed a powerful shock; Set up a case-handling team to combat cybercrime, strengthen the analysis of new cases, and improve the professional level of case handling. Wang Qinjie reminded that in daily work and life, don’t trust calls of unknown origin, such as posing as public security law, customer service, leaders, relatives and friends, don’t click on any unknown web links, don’t scan any unknown QR code, don’t remit money or transfer money to strangers, especially don’t join strange QQ groups, WeChat groups, share screens at will, and don’t enter account passwords according to instructions from people in the group.

&emsp; &emsp; Jing Tao, director of the Criminal Investigation Bureau of the Provincial Public Security Department, said that the public security organs in the province are keeping a close eye on the changes in the situation of telecommunication network fraud crimes, and will continue to deepen the construction of technical countermeasures with relevant departments, continuously expand the coverage of early warning and prevention, and build a barrier to interception and countermeasures. The first is to strengthen interception and plugging. On average, 61,000 fraudulent phone calls, 63,000 fraudulent text messages, 42,000 fraudulent websites and fraudulent apps were intercepted every day, blocking users from accessing fraudulent apps and URL links for 107.5 billion times. The second is to strengthen early warning and discourage. The average daily output of early warning information was 46,000, and 15.8 million people were successfully discouraged. The total amount of emergency warning decreased for 20 consecutive months. The third is to strengthen the investigation and control of funds. Relying on the national anti-fraud big data platform, we established a 7×24-hour response mechanism with 3,828 banks and 124 payment institutions, stopped and frozen fraudulent funds in accordance with the law and in an orderly manner, efficiently and steadily returned funds, and effectively recovered the losses of victims.

&emsp; &emsp; Jiang Dunbin, vice president of the provincial court, said that in recent years, telecommunication network fraud has occurred frequently, and at the same time it has shown a trend of collectivization, cross-border, chain and industrialization. From January to November this year, the provincial courts concluded 1319 first-instance cases of telecommunication network fraud and sentenced 2185 defendants; 8,349 cases of related crimes helping information network criminal activities were tried and 10,750 defendants were sentenced; 3,794 cases of crimes committed by concealing and concealing were tried, and 5,778 defendants were sentenced. Jiang Dunbin said that in recent years, telecommunication network fraud has occurred frequently. Ordinary people should pay attention to and prevent telecommunication network fraud, actively learn anti-fraud knowledge, protect personal information, choose formal channels when investing in financial management, and do not illegally buy, sell or rent mobile phone cards and bank cards.

&emsp; &emsp; In the next step, political and legal organs at all levels in Shandong will continue to promote the three-year campaign to crack down on telecommunication network fraud and illegal crimes, intensify the crackdown, strengthen early warning and dissuasion, strengthen comprehensive management, and resolutely protect people’s lives and property.

Rulu： Counterattack and Challenge in Screen and Reality

In the glamorous but hidden world of entertainment circle, Rulu has gradually grown from a supporting role to a high-profile actress with her excellent acting skills and firm professional attitude. Recently, her role in the new drama has been overwhelmed by Tanya, which has aroused people’s deep thinking about her artistic career and life situation.

Early experience and growth

As early as when Rulu was growing up, acting was like her destiny takes a hand’s track. She was passionate about art since she was a child, and her whole family supported her to pursue the road of performing arts. She showed extraordinary performance potential in middle school, and then she was admitted to Beijing Film Academy. At this stage, she not only laid a solid performance foundation, but also made many friends in the circle. She worked hard, quickly accumulated experience in the young age, and gradually emerged in many film and television works.

Career: from supporting role to leading role

Rulu’s career can be said to be a history of struggle. She showed a good acting talent in her early performance of "The Seven Fairies with Joy". However, she did not stop because of this. Instead, she worked hard and participated in the performance of the role of Chinese Princess in Empresses in the Palace, which really made the audience remember her name. The role of Hua Fei is not only complicated, but also full of challenges. Rulu, with his deep understanding of the role and superb acting skills, successfully injected soul into this role. After that, Rulu got more and more starring opportunities and began to dominate some TV series, which was widely loved by the audience.

Artistic Achievement and Public Image

Despite the prosperous career, Rulu’s road is not smooth sailing. Recently, she became a topic again because of Tanya’s pressure on her new drama. Both the professional competition and the capital operation behind her made people think deeply about her situation. Some people think that Rulu’s performance level is not enough to compete with Tong Yao, while others point out that this is a cold evaluation of the actor’s value by capital. In any case, Rulu’s every gain and loss on the set conveys a fighting spirit, which is also the quality that she has always been praised.

External evaluation and social relations

In the circle, Rulu maintains good relations with many powerful actors, but there are also some competitors. This complicated social circle has helped her to move up in her career, and she is also facing more challenges. Actors who have worked with Rulu have praised her professional ability and considered her a trustworthy and reliable colleague. Because of this, Rulu’s reputation in the industry is constantly improving.

Strength and reflection in adversity

Although Rulu has made remarkable achievements in her career, the external pressure and the game of capital are still an unavoidable reality for her. When she was overwhelmed by Tanya in the new play, many fans felt aggrieved for her, but she chose to respond to all this with a positive attitude on social media. She once said: "I only want to work hard in my own field and not be influenced by the noise of the outside world." Her attitude makes people sigh: in the highly competitive entertainment circle, self-preservation is a rare quality.

Enlightenment to society

Rulu’s experience tells us that tenacity and professionalism are the magic weapons to meet the challenges in the workplace. Facing all kinds of external evaluations and capital games, only by maintaining inner firmness and love for art can we gain a foothold in the ever-changing circle. From a supporting role to an actress today, Rulu’s story has undoubtedly inspired many dream catchers: success requires not only talent, but also courage and confidence to meet challenges. In this competitive era, Rulu’s persistence and efforts are worth learning from all. Just like her own motto: "Every moment of hard work is worth celebrating".

Revealing the ＂Little Guard＂ of Automobile —— Important Mission and Replacement of Fuel Filter

When you are driving your car on the road, enjoying the speed and passion, have you ever thought that there is a quietly dedicated widget to escort your safe and stable operation? Yes, it is the fuel filter.

Although the fuel filter is inconspicuous in the complex mechanical world of the automobile, it plays a vital role, just like a loyal guardian, silently guarding the normal operation.

First, the main function of the fuel filter

The main function of fuel filter is to filter impurities in fuel, such as rust, dust and tiny particles. Clean fuel is the guarantee of efficient engine operation, and fuel filter is the key link to achieve this goal. For example, if the rust in the fuel enters the engine, it may wear the precision parts and affect the injection accuracy of the fuel; Dust and fine particles may be blocked, resulting in uneven fuel injection.

Second, the hazards of not replacing the fuel filter in time

1, affect the engine performance

With the increase of service time, the filtration effect of the filter decreases gradually, and impurities will enter the fuel system. This may lead to the blockage of the fuel nozzle, uneven fuel injection, weak acceleration of the vehicle and obviously worse power than before. For example, when overtaking, you will obviously feel the lack of power, which will affect driving safety.

Impurities may also be damaged, reduce its working efficiency, and even cause failure, resulting in the engine not starting normally. For example, in the cold winter, the fuel pump failure may make the vehicle unable to start, which brings great inconvenience to travel.

2, shorten the engine life.

Impurities entering the engine will aggravate the wear of internal components, such as pistons, cylinder walls and so on. In the long run, it will reduce the service life of the engine and increase the maintenance cost. For example, serious wear may lead to engine burning and further damage to the engine.

Third, the method of judging whether the fuel filter needs to be replaced

1, according to the mileage and time.

Automobile manufacturers usually recommend the replacement cycle of fuel filters in vehicle maintenance manuals, which is generally about 20 thousand kilometers to 40 thousand kilometers, and the replacement cycle may be shorter. When the vehicle approaches or exceeds this mileage, or when it is used for a long time but has less mileage, it should be replaced. For example, if your vehicle has been used for three years, but the mileage is only 15,000 kilometers, you may need to replace the fuel filter, because the performance of the filter will decrease after a long time.

2. Observe the change of vehicle performance.

Power drop: If it is found that the acceleration of the vehicle is weak and the power drops obviously, it may be that the fuel filter is blocked, resulting in poor fuel supply. For example, when climbing a hill, it feels harder than before, and the accelerator is slow to respond.

Increased fuel consumption: Because the filtering effect becomes worse, impurities enter the fuel nozzle and affect the fuel injection and combustion efficiency. Under the same driving conditions, the fuel consumption is significantly higher than before. For example, a box of oil used to run 500 kilometers, but now it can only run about 450 kilometers.

Engine jitter: Especially when driving at idle speed or low speed, the fuel pressure may be unstable due to the blocked fuel filter. For example, when waiting for the traffic lights, you can obviously feel the engine jitter.

3. Check the fuel system fault light.

Some vehicles are equipped with this light. When the fuel filter is seriously blocked or has other faults, the fault light may light up. If your vehicle fault light is on, check the fuel system, including the fuel filter, in time.

4. Disassembly inspection

For those who have certain knowledge and skills in automobile maintenance, the fuel filter can be removed for inspection. Observe whether the appearance is damaged or deformed, and gently shake it to listen to the sound of impurities. If the filter is abnormal in appearance or can obviously feel impurities inside, it needs to be replaced.

Iv. Precautions for replacing fuel filter

1, choose the right filter

Adapt to the car model: make sure that the fuel filter you buy matches your car model. Different models of fuel filters may be different in size, interface type and filtration accuracy, and the appropriate model can be determined by consulting the maintenance manual and consulting the automobile dealer or professional maintenance personnel. For example, the fuel filters of a medium-sized SUV and a medium-sized SUV may be quite different in size.

Reliable quality: select brand products with reliable quality to ensure the normal operation and long service life of the fuel system and avoid the damage caused by fake and shoddy products to vehicles. For example, well-known brands of fuel filters usually use high-quality filter materials, which can better filter impurities.

2. Prepare the right tools

Common tools: Replacing the fuel filter usually requires tools such as wrenches and screwdrivers. Before replacing, make sure you have the right tools and check whether they are in good condition.

Protective articles: Because replacing the fuel filter may involve fuel contact, it is recommended to prepare gloves and other protective articles to protect your own safety.

3. Preparation before replacement

Stop the vehicle and cool the engine: Before replacing the fuel filter, park the vehicle in a safe place and turn off the engine. Wait for a while to avoid being replaced.

Relieve the fuel pressure: Before removing the fuel filter, it is necessary to relieve the pressure in the fuel system. The release methods of different models may be different. Generally, the pressure can be released by unplugging the fuel pump or relay and starting the engine to turn it off naturally. Before doing this, be sure to consult the vehicle’s maintenance manual to ensure the correct operation method.

4, matters needing attention in the process of replacement

Caution: When removing and installing the fuel filter, be careful to avoid damaging the fuel pipeline and other components. Be careful not to let impurities enter the fuel system.

Correct installation: ensure that the fuel filter is installed correctly and the direction is correct. Generally speaking, there will be a sign on the filter indicating the direction of fuel flow. Install the filter correctly according to the sign to ensure its good sealing.

Moderate fastening: When installing the fuel filter, pay attention to moderate fastening. Too loose may lead to fuel leakage, and too tight may damage the filter or fuel line.

5. Inspection after replacement

Check the tightness: after the replacement, carefully check whether there is fuel leakage at the joint between the fuel filter and the fuel pipeline. You can start the engine and observe it for a period of time to ensure that there is no leakage.

Clear the fault code: If the fault light of the vehicle lights up before replacing the fuel filter, it may be necessary to use a diagnostic tool to clear the fault code after replacement. If the fault light is still on, check the fuel system for other problems in time.

In a word, it is necessary to operate carefully when replacing the fuel filter, select the appropriate filter, prepare tools, replace it correctly and make a good inspection to ensure the normal operation of the fuel system and the safe driving of the vehicle. If you are uncertain about the replacement process, it is best to seek the help of professional maintenance personnel.
