Recently, Iqiyi launched the movie label of "Action Master Season" online, and launched four action-type films: Stop the Horse and Take the Knife, Arrogant 2, Stop Evil, and Strange Knife. It combines action, martial arts, suspense, comedy, drama and many other elements. Among them, As a pure martial arts genre in ancient costume, The Stranger’s Mad Knife describes an reclusive charcoal seller Tian Anye who was inadvertently involved in the court coup to usurp power. He joined forces with other chivalrous men such as Qin Gu, the former head of the Prince, to stand up and uphold justice for the prince’s widow Nie Linger and the oppressed people in distress, showing the chivalrous demeanor in China’s traditional ethics. This film is devoted to the genre creation of costume martial arts, especially in the aspect of genre narration and fighting action. On the basis of returning to the classic Chinese action genre film, it has achieved some transcendence.

Action types are the classic types in Chinese movies, among which the action types in Hong Kong movies are the epitome of Chinese action types. After more than half a century’s development, they reached the peak of aesthetics in the 1980s and 1990s. The chivalrous spirit led by China’s Confucianism, such as getting rid of violence, helping justice, once upon a time in america and forbearing practice, has become the subjective ideological output of these films; A series of action elements, which combine the performance of China North School and the actual combat of China South School, and are designed according to the specific characters’ personalities and performance space, have become another essence of Chinese action films. Therefore, Chinese action movies have a strong artistic vitality and are constantly advancing aesthetics; This kind of films not only have a wide audience in Chinese-speaking areas, but also helped China films to enter the world mainstream film market twice in the early 1970s and the early 21st century, thus realizing the effective international spread of China films.

Due to the shortage of talents, lack of innovation, capital flight and other reasons, this classic China film has shown less and less situation in the Chinese film market in recent years, and its performance in the cinema market is also very weak. However, judging from a series of data of online movies and online dramas in recent years, this content creation type with the most China characteristics still has a considerable number of potential audiences in China and other parts of the world, and the fundamentals of its audience have not changed fundamentally, but the broad audience, especially the cinema audience, has a strong demand for its innovation, and there is no way out to repeat the past. The film labels of "Stranger Knife" and "Action Master Season" launched by iQiyi are undoubtedly the response to this appeal.

The Stranger Knife follows the theme and genre narration of traditional martial arts films, but it adds new elements on this basis. First, the film does not set Tian Anye’s formulated chivalrous character, but focuses on the passivity of his participation in rescuing Nie Linger’s mother and son, and his chivalrous actions are gradually stimulated in this passivity, thus giving this character a more three-dimensional character and more growth arcs.

At the same time, the film also gives more folk and individual expression to Nie Linger’s feelings, and gives a rich display to Qin Gu’s behavior of being an enemy and a friend, and also gives a humorous portrayal to another key chivalrous man, Qiansun Zhao. This characterization not only increases the appreciation of the film, but also gives the film more humanistic value and modernity.

Secondly, on the specific narrative level, The Stranger’s Mad Knife did not follow the revenge routine of traditional martial arts films step by step, but expanded in the present. For example, when Tian Anye, Qiansun Zhao and Qin Gu took Nie Linger and his mother to break through, the film designed four barriers that they wanted to break through, and each barrier was animated in the film. Tian Anye and others’ breakthroughs in these four barriers were like the breakthrough in the game. This narrative setting makes the film more contemporary and can generate more empathy with the mainstream audience in the new media era.

The film’s innovative performance is also reflected in the action design and super weapon design. First of all, the film designs corresponding actions according to the characters’ personality and behavior characteristics, so as to better show the artistic charm of action types. For example, when Tian An Ye began to rescue Nie Linger’s mother and son, his identity was a charcoal seller, and the carbon element occupied the dominant position in the picture. The action design around Tian An Ye was also full of carbon element, especially in the scene where he defeated the Fei Fei army in the dark with a charcoal stick. The burning charcoal stick danced like fireworks in the night, which produced a strong visual impact. In the second half of the film, the audience knows Tian Anye’s true identity as the head coach of the Mo Dao Army, and his fighting action is no longer full of charcoal elements but the actual combat of Mo Dao.

For Zhang Xuqing, the leader of the anti-angle flying army, he was suppressed by the King of Qi, and threatened by Liu Bingfeng, the deputy leader. In this kind of crevice, the founder designed weapons with long and short knives for him, which highlighted his toughness in fighting. Qin Gu’s style in the film is a white hat with a black veil. She has a pure personality and a gray area that she is most reluctant to mention. She strives to solve the confrontation quickly. Therefore, the film designs her movements to highlight the characteristics of quickness. When she shoots, the knife will not be drawn, and she will win immediately, emphasizing "the martial arts in the world, only fast and unbreakable".

Secondly, the film highlights Tian Anye’s strange knife and its fighting. According to historical data, the film restores the strange knife used by Tian Anye according to the actual size, which is about 2.6 meters long and weighs dozens of kilograms. Such a super weapon has never appeared in previous martial arts shooting. The creative team also designed a new knife method according to the personality of the characters and the characteristics of this knife. This knife method was particularly fully displayed in the scene where Tian Anye fought Zhang Xuqing’s long and short knives with a strange knife at the end of the film. The two weapons formed a sharp contrast. The fighting tactics of the knife method and the rigidity and softness of your coming and going all reflected the bold innovation of the creative team in weapon design and action guidance, which further expanded the action type elements of domestic martial arts films.

As a martial arts film with an expanding mission, the film also has room for improvement. The first is the recurring camel phantom, which seems unnecessary in the play. Secondly, the four barriers of film design lack a sense of progressive upgrading, which reduces the sense of game entertainment of the film. However, at a time when the action genre, especially the martial arts genre, needs to be revived, the brand of "Action Master Season", especially "A Stranger’s Sword", is undoubtedly of great significance.

Special feature of 1905 film network "It was successfully held for 15 sessions, witnessing 87 projects entering production, 72 participating in major film festivals at home and abroad, 44 being shortlisted for Class A film festivals, and 63 films being shown in cinemas at home and abroad." At the 25th Shanghai International Film Festival, the host chose to use such a set of figures as the opening remarks.

Behind the figures are the achievements made by the venture capital unit of Shanghai Film Festival in the past 16 years. By providing docking services such as incubation, financing and promotion for projects of different scales and stages, Shanghai Film Festival Venture Capital has become an incubator for young directors’ works and an important platform for the industry to discover new Chinese speakers.

It will be released on June 16th, and the young director’s feature film debut is one of the examples. In 2017 and 2019, the project was selected by Shanghai Film Festival Venture Capital twice, and in 2021, it was selected as the "One Concern" unit of Cannes Film Festival. Starting from venture capital, going to international film festivals, and then landing on the cinema screen, Street Kids has gone out of the "idealized" path.

On the same day, director Najiazuo also came to the scene where the honor was announced, telling the significance of venture capital to him. "In 2017, I met the producer because of venture capital. In 2019, the filming was completed, and I went to many film festivals. I always wanted to go home and see it. Time flies. I hope I can still work as hard as filming Street Kids when I am 40 years old!"

As the 25th Shanghai International Film Festival, originally scheduled to be held in 2022, was postponed to 2023, the organizing committee received a total of 679 project declarations in two years, and the competition was particularly fierce. After selection, 33 projects stood out.

In the end, various honors were announced: the director’s new work "Bye-bye, Bye-bye" won the "Recommended Project in Production"; The film "Wild Crane in the Clouds" with the theme of ethnic minorities won the "Recommended Project by Young Directors"; The director’s "Yao Yao Zhuan" and Gao Ming’s "Two Time Zones" were awarded "Creative Recommended Project" and "Special Recommended Project" respectively.

#01. The genre theme is novel and diverse.

"I think the diversity of this venture capital project is very good, not limited to a certain type of theme." This is the biggest feeling of the annual recommender and producer of project venture capital.

Bye-bye, which won the honor of "recommended project in production", focuses on the "bye-bye" belief culture in the relatively small Minnan area, and thus shows the living conditions of local elderly women. Similar themes are very rare in the domestic market, which also makes the judges shine. The recommendation language reads: "The theme is novel, the film language is distinctive and the completion is high."

Producer Kick told 1905 Film Network that she and director Ye Qian are both from Fujian, and they are particularly familiar with the stories and female images in the film. Since the debut novel "Sweet Potato Dried with Rice", Ye Qian has been insisting on the creation of similar themes.

"Paying attention to the elderly women and taking root in the soil of southern Fujian, Ye Qian has always been very firm. He will not pick up other people’s adaptation projects, and he is very determined to do his own things, which is very valuable and rare."

It is this persistence that made the director successfully move to play the heroine. "After reading the story, she said that she had not seen the role that moved her so much for a long time, which reminded her of the director."

Starting from one’s own life experience, combining personal experience, social observation and thinking with audio-visual language and transforming it into a powerful movie story, which is exactly what many outstanding projects of this venture capital have in common.

The same is true of Wild Crane in the Clouds, which won the honor of "Young Director’s Recommended Project". Director Ahmad McMaiti chose to tell a familiar "Xinjiang Story" in a humorous way, which left a deep impression on the judges from Uighur lines to strong regional cultural characteristics and ethnic customs.

The recommender concluded: "Personal experience and feelings are the best fulcrum for the director’s early creation. Rooting the seeds of creation in life may grow something with strong imagination. "

Not only do you dare to focus on minority themes in topic selection, but this year’s venture capital finalists are also showing a trend of blooming in variety. Youth, suspense, sports, family, crime, comedy, love, fantasy and martial arts are all involved, taking into account art and business. The enthusiasm and vision presented by young creators are gratifying.

#02 Hot Women’s Issues with Realistic Themes Get Attention

In recent years, the market feedback of realistic works has been fierce, which has frequently triggered heated discussions in the society and staged a box office success of "small and broad". Coupled with its relatively low cost and shooting difficulty, realistic themes have become the focus of young creators.

For example, the director’s new work focuses on education and medical care, which are closely related to people’s livelihood, and interweaves them with dramatic techniques. He explained the theme of the film like this: "When fairness and justice are not good for you, will you still insist on fairness and justice?"

Faced with this controversial topic, Chen Zhixi bluntly said that the director could be bolder, take a "stinging" step forward on the basis of the original script, and more directly poke the "pain point" of the audience and society.

Different from the warm tone of Trading Destiny, From Now on, written and directed by young director Yang Guomin, hopes to maintain a cruel and true "hard spirit" and "force generate’s true feelings in a cruel way" when showing the special father-son relationship of the family with cerebral palsy.

While the three judges affirmed the quality and strength of the script, they also pointed out from the market point of view that the audience would like to see the story of how the protagonist in trouble faces life actively and meets challenges, which can increase the initiative of some characters.

"In the current environment, the audience hopes that the film can give it some hope and courage while empathizing, which also makes warm realism a preferred type in the current market," Chen Zhixi said.

Among many realistic works, the increase of women’s themes is also a significant trend. For example, Night Running tells about the situation and choices of three generations of women, Taste of Chinese focuses on the growth experience of post-90 s girls, and Playground this Friday puts the pressure of single and full-time mothers on the table.

When Chen Meiyu, the director and screenwriter of "Mom at the same table", took her 7-year-old daughter to the public presentation site, it quickly attracted the attention of the judges and guests. And her work is also adapted from personal experience. "I took the college entrance examination five months pregnant and reported to the university when I was nine months pregnant." Mother at the same table "tells the story of female college students taking their children to college."

In Chen Meiyu’s view, when it comes to "early pregnancy mother", many viewers will inevitably have curiosity, and the heroine she created is to break the stereotype of the audience: she can argue with the school for the right to go to school, boldly respond to her ex-husband’s struggle for custody, and dare to tear open the wound to tell her story to the public. "The first key word is fierce. She is not bitter at all, but she is optimistic and brave."

During Chen Meiyu’s presentation, producer Chen Zhixi was moved to tears. She bluntly said that the real and special story emotion is the biggest advantage of this project, which makes it both topical and market space.

"She has got a natural good topic, and the next step is to have a good text, find universality under a special story, and the mother-daughter emotion should be able to make the audience empathize."

Indeed, both "Mother at the Same Table" and the above-mentioned female-themed projects are paying attention to women’s living difficulties and inner world from different dimensions. Several judges also reminded the creators that the shaping of female images and the choice of female actors are very important and will become the key to whether the audience can substitute and empathize.

#03 Art or business to be decided

"Do you want to make a movie to express yourself, or do you want the audience to buy tickets to go to the cinema? These are two completely different goals." A sentence from the judges triggered on-the-spot thinking.

In his view, art or business, personal expression or market-oriented, this is the direction that needs to be determined in the early stage, and it is also a problem that many creators have not thought clearly.

Wu Ershan explained: "The new director’s project needs to have a clear goal, not both sides. For example, if it is the direction of film festivals, it needs to maintain the originality of creation and the creativity of film language, while maintaining low cost; However, if the target is the mass market, then you need to consider what types of elements your work has, whether the organization is mature, whether it meets the needs of the market, and whether the budget can match. "

The producer of Bye-bye, Bye-bye has a clear position in this respect. As a narrative film with a strong author style, they made it clear from the beginning that they would take the direction of film festival exhibition, and they also hoped to make targeted regional announcements in Fujian and Guangdong during the cinema stage.

"The key to a small-budget movie is to find its unique audience, recognize its own advantages, find audiences with the same roots and similar cultural soil, and it is good to’ punch through’ an area without eating into a big fat man."

The same is true of the romantic film Time Hotel, which was also selected as a "project in progress". The total budget of the project is only 3.5 million yuan, and the filming has been completed and entered the post-production stage.

Director Yixiang Zhai said, "I hope to make a movie with aesthetic feeling and adult love theme. At present, there are few similar movies depicting adult emotions in the domestic market. I had expectations for the market from the beginning, so I was more concerned about the budget than the producer. I finished shooting in 26 days and have been saving the budget. "

"We should not only see what everyone is doing, but also figure out what we can do." This is Xin Yukun’s message to young filmmakers.

He is also very envious that young creators can have a platform for exchange and learning, such as "venture capital". "In the process, you can know more like-minded friends, and you will also revise and sort out your own creative concept and film concept. This is the meaning of venture capital."

Wu Ershan hopes that the new directors can really exert their strength on the word "new". "We don’t need him to be perfect or mature, but we want to see new themes, new ideas and new film languages. This is the primary standard. With this longboard, other shortcomings can be slowly filled."

Starting from the "new", the next China story is on its way to the world.

　　CCTV News:Not long ago, the Guangdong Higher People’s Court, in the second instance, changed the result of a drug case. The defendant was commuted from innocence to life imprisonment. There is nothing special about this drug case itself, but its trial process is extremely tortuous and difficult. The case has gone through seven sessions in the past four years. From innocence to life, what kind of tortuous experience is behind the verdict?

　　Why did the thought change from "zero confession" to writing a confession?

　　In July 2019, a letter sent from Panyu District Detention Center in Guangzhou was placed on the desk of He Xiongwei, the prosecutor of Guangdong Provincial People’s Procuratorate. The letter was sent by Liu Youdi, a criminal in a drug trafficking case. She wrote in the letter, "Please meet He Xiongwei. Now I am willing to plead guilty, admit my mistake and truthfully explain the case." Just a month ago, Liu Youdi was sentenced to life imprisonment by the Guangdong Higher People’s Court for drug trafficking. In court, she never pleaded guilty. So what makes her mind change so dramatically now? What kind of waves are behind this drug case?

　　On December 21, 2015, the Public Security Bureau of Panyu District, Guangzhou received a report that someone was dealing in drugs near a building in Panyu District. After grasping the clues, the police immediately went to arrest. The location of the arrest was in an alley. After groping, the police quickly found the target vehicle. After exploring the surrounding terrain, they made a detailed plan and launched the arrest operation.

　　Police of Panyu Branch of Guangzhou Public Security Bureau:As soon as I walked past, I knocked on the woman’s window. She opened the window. When I opened the window, I saw that she seemed to have left the steering wheel with her hands, and she was still playing with her mobile phone. I felt that it was time. I immediately put my hands in and controlled her hands.

　　At that time, the woman in the car did not resist too much, and the arresting personnel quickly controlled her, and other police officers immediately gathered around and searched the vehicle. Soon, they found a bag on the mat in the passenger seat.

　　Police of Panyu Branch of Guangzhou Public Security Bureau:Before I opened it, she said that the bag was not mine, and she knew that it must be illegal, so she said that it was not mine.

　　The woman who found drugs in the car argued that she was framed.

　　After testing, the items contained in the plastic bag extracted by the police from the woman’s car that day were confirmed to be ice, weighing 1000.06 grams. As a result, Panyu police detained the female object Liu Youdi, but in the subsequent trial, she always denied that the bag of ice was her own. Liu Youdi said that she is a Wechat business who is engaged in bird’s nest business. On that day, she took some bird’s nest for her friend Zhou to help sell, and this bag was put in the car when Zhou left. Liu Youdi said that there was an economic dispute between her and Zhou, so she suspected that this bag of drugs was used by Zhou to frame herself.

　　In the subsequent investigation, the police also found that just the day before Liu Youdi was arrested, she had been to Shanwei, Guangdong Province, and her own explanation was to go to Shanwei to find someone to buy bird’s nest. Liu Youdi not only refused to admit this series of evidence pointing to her suspected crime, but also had his own set of rhetoric, which also made the prosecutor of Panyu District Procuratorate doubt whether he could approve the arrest.

　　Zheng Shaochun, Procurator of Panyu District People’s Procuratorate, Guangzhou:Then at that time, the preliminary judgment was that there was no direct and objective evidence to rule out her excuses, including my own manager’s opinion, and they all tended to say that the case was in doubt and not arrested.

　　Get the key words of new evidence to attract the attention of the prosecution

　　Seven days is the time limit for the procuratorate to review the arrest. Just as the prosecutor was preparing to make an opinion not to approve the arrest, the public security organ provided new evidence in time, a WeChat record of communication related to Liu Youdi. Among these massive electronic evidence, some key words attracted the attention of the prosecutor.

　　Zheng Shaochun, Procurator of Panyu District People’s Procuratorate, Guangzhou:He said that if he was afraid of being arrested by the police or the police, he mentioned some very sensitive words. Also said that you brought me several sets, and mentioned some similar transactions. At that time, after listening to this recording, we strengthened our conviction and should be able to rule out her excuse.

　　The case encountered twists and turns when it entered the stage of review and prosecution.

　　According to the preliminary investigation and evidence collection, Panyu District People’s Procuratorate approved the arrest of Liu Youdi according to law, and then the case entered the stage of review and prosecution. The prosecutor found that from the chat record, Liu Youdi had a very close relationship with Zhou who appeared in her car on the day of the incident. It should be said that Zhou was also a very key witness in the case. But in the existing evidence, there is no material of her testimony. Under the existing evidence, the procuratorate can only prosecute Liu Youdi for the crime of illegal possession of drugs.

　　Wang Chaoxia, Procurator of Panyu District People’s Procuratorate:In this case, through WeChat chat, it can be confirmed that this drug was taken by Liu Youdi from other places. At least there is illegal possession of drugs involved, which can be proved to be Liu Youdi’s. At that time, in the absence of drug buyers, we temporarily transferred the crime of illegal possession of drugs to Panyu District People’s Court for prosecution.

　　Obtain the testimony of key witnesses and prosecute for drug trafficking

　　In this way, after three court sessions, that is, one year after the crime, the public security organs heard new news. They found the key witness Zhou, and got her transcript materials. In her testimony, Liu Youdi was mentioned to have bought and sold drugs. As a result, the nature of the case changed. So Panyu District People’s Procuratorate changed the charges against Liu Youdi and brought a public prosecution to the court for drug trafficking.

　　Wang Chaoxia, Procurator of Panyu District People’s Procuratorate:After the change of prosecution, because the number of drug trafficking has reached more than life imprisonment and reached the standard of upward adjustment, the case was withdrawn after communicating with the court and was raised to the Guangzhou People’s Procuratorate for prosecution.

　　The prosecution changed the accusation and waited for the court to hear it.

　　After obtaining new evidence, the procuratorate changed from "illegal possession of drugs" to "drug trafficking" and filed a public prosecution with the court. However, the next court trial process was full of twists and turns. In the trial, the first problem is the "zero confession".

　　Chen Shufen, Procurator of Guangzhou Municipal People’s Procuratorate:We have studied all the evidence very carefully, and we have formed an inner conviction by synthesizing the evidence of the whole case. The evidence of the whole case should meet the prosecution standard of clear criminal facts and sufficient evidence.

　　The accusation is proved guilty through two aspects of evidence.

　　In August 2017, the Guangzhou Intermediate People’s Court held a hearing on this drug crime case. In court, the confrontation between the prosecution and the defense was very fierce. Since Liu Youdi did not plead guilty from beginning to end, it is necessary for the procuratorate to charge her with guilt. Work hard on the evidence.

　　Chen Shufen, Procurator of Guangzhou Municipal People’s Procuratorate:So to accuse a "zero confession" crime, we need to have a lot of objective evidence to support it, as well as the corresponding verbal evidence, that is, witness testimony. The objective evidence and verbal evidence can form a complete proof system, and in this case, we can identify the crime.

　　In the court trial, the prosecutor mainly confirmed each other through objective evidence and verbal evidence, proving that the case has reached the standard of clear facts and sufficient evidence, and can eliminate reasonable doubt, which is enough to confirm Liu Youdi’s conviction for drug trafficking.

　　Defender insists on innocent defense and questions witness testimony.

　　On the other hand, Liu Youdi’s defenders insisted on pleading not guilty. They believed that the public security organs did not collect evidence from the witness Zhou until one year after the crime, and many contents in the testimony were inconsistent with what the witness said in court. The defenders questioned the authenticity of this witness’s testimony. They thought that Zhou might lie and could not rule out the situation that she framed Liu Youdi.

　　The facts are unclear and the evidence is insufficient.

　　On February 2, 2018, the Guangzhou Intermediate People’s Court pronounced the case in the first instance. The court held that the evidence on which the defendant Liu Youdi constituted the crime of drug trafficking did not form a complete proof system, did not meet the legal proof standard of sufficient evidence, and did not meet the conviction requirements of clear basic facts and conclusive basic evidence, and could not rule out reasonable doubt. According to relevant laws, the defendant Liu Youdi was acquitted.

　　The prosecution filed a protest to supplement the corresponding evidence.

　　After the verdict of the first instance came out, the prosecutors also began to reflect. They reorganized the evidence materials of this case and thought that although the witness testimony in court was repeated, the evidence of the case did not change fundamentally. As long as the relevant evidence was reinforced, the case could still reach the conviction standard of clear criminal facts and sufficient evidence, so the Guangzhou People’s Procuratorate decided to lodge a protest against this case.

　　Chen Shufen, Procurator of Guangzhou Municipal People’s Procuratorate:For this case, we feel that we should be convicted and then acquitted. We also feel that the evidence is sufficient, and our prosecution is supported by evidence and has a legal basis. In this case, we feel it is necessary to push this lawsuit forward. It is by protesting this litigation procedure that this second trial procedure is pulled.

　　After the protest opinions were reported step by step, they were supported by the Guangdong Provincial People’s Procuratorate and the Supreme People’s Procuratorate. At the same time, the Guangdong Provincial People’s Procuratorate also put forward some suggestions to strengthen the relevant evidence.

　　How does the prosecution consolidate the evidence when entering the second trial stage?

　　The case entered the second trial stage, and it was handed over to He Xiongwei, deputy director of the First Procuratorate of Guangdong Provincial People’s Procuratorate. However, in his view, this case still needs to be strengthened in some evidence.

　　After taking over the case, the prosecutor He Xiongwei quickly entered the marking work. At the same time, he also browsed the relevant reports about the case online, and some netizens’ doubts about the case coincided with his thoughts.

　　He Xiongwei, Deputy Director of the First Procuratorial Department of Guangdong Provincial People’s Procuratorate:I also saw some comments at that time. Many netizens said that the suspected crime never ensured that the innocent people would not be investigated by law. Whose one kilogram of drugs was it? There must be a drug crime in it. You let this man go, then who should be responsible for this kilo of drugs?

　　Who should be responsible for this kilogram of drugs? It is also the fact that the prosecutor He Xiongwei wants to find out. Liu Youdi said that he went to Shanwei to buy bird’s nest the day before the incident. After consulting all the files, he questioned Liu Youdi’s remarks.

　　He Xiongwei, Deputy Director of the First Procuratorial Department of Guangdong Provincial People’s Procuratorate:Bird’s nest is counted by one lamp. She said how many, and then there were a lot of drug code words. For example, she mentioned that I’m not afraid of being detected by the police, and I don’t take drugs.

　　These inferences of the prosecutor need to be proved by more solid evidence. If there is no stronger evidence, it is still very difficult to change the judgment of the case.

　　Prosecutors lead the way to find drugs to go home.

　　After reviewing the files repeatedly, He Xiongwei found a person, a key breakthrough. He analyzed that if Liu Youdi went to Shanwei to buy drugs, then the man she contacted in Shanwei at that time, who was called "Lao Chen", was probably her family. Coincidentally, in another drug crime case handled by He Xiongwei, the name "Lao Chen" also appeared.

　　He Xiongwei, Deputy Director of the First Procuratorial Department of Guangdong Provincial People’s Procuratorate:It happened that I was lucky enough to handle another case, which was a drug trafficking gang. In the process of reviewing the case file, I found that all four people in this case identified a person named "Lao Chen". At that time, I thought about the case of Liu Youdi, whose last family was also called "Lao Chen".

　　After in-depth investigation, He Xiongwei found that the "Lao Chen" in these two unrelated cases were very similar. They both lived in Shanwei, and many characteristics were consistent. More and more evidence proved that the two "Lao Chen" were the same person. So, He Xiongwei immediately informed the public security organs to investigate this "old Chen" in depth, and at the same time, he also asked the court to take Liu Youdi, who had been released on bail pending trial, into custody.

　　He Xiongwei, Deputy Director of the First Procuratorial Department of Guangdong Provincial People’s Procuratorate:We also issued an official letter suggesting that the provincial court arrest her. The provincial court made a decision to arrest after the collegial panel’s deliberation and approval.

　　“preceding player (in card or mahjong playing)"Arrested to grasp the core evidence of the case.

　　Soon, with the cooperation of public security departments at all levels, the criminal suspect Chen Mou was arrested in Shanwei. After investigation, the criminal evidence of drug trading between Chen Mou and Liu Youdi also surfaced. In this way, the key evidence of this case was finally found. In the second trial, this evidence also became the core evidence against Liu Youdi for drug trafficking. In the trial of the second instance of Guangdong Higher People’s Court, the prosecutor presented several sets of evidence to prove that Liu Youdi had the fact of selling drugs, but in the face of these evidences, Liu Youdi once again argued that he was innocent for various reasons.

　　On June 14, 2019, the Guangdong Higher People’s Court pronounced the case in the second instance. The court held that, in view of the fact that Liu Youdi had been found guilty of drug trafficking in the second instance, the Guangdong Provincial People’s Procuratorate’s protest against Liu Youdi’s request for a revised sentence for drug trafficking was found to be sufficient and adopted. Therefore, the court revoked the acquittal of the first instance and considered that Liu Youdi constituted a drug trafficking crime.

　　The trial of the case ended, but the prosecutor’s heart was still unresolved.

　　This case was changed from innocence to life imprisonment, which made all the judicial personnel who worked hard feel very relieved, but prosecutor He Xiongwei still had a knot in his heart, that is, Liu Youdi never admitted his guilt.

　　Before the trial of the second instance, He Xiongwei went to Panyu several times to interrogate Liu Youdi. Although she never pleaded guilty in court, on July 9, 2019, less than one month after the verdict of the second instance was pronounced, she wrote such a letter in Panyu District Detention Center, saying that she wanted to see the prosecutor He Xiongwei and expressed her willingness to admit her crimes. Liu Youdi said that she had a boyfriend who was a wealthy businessman. Since she had no source of income, her boyfriend gave her some money to do some business. But she spent the money elsewhere.

　　Criminal Liu Youdi:Gave me money, and then I didn’t do business, so I renovated the house without telling him. After decorating the house, I bought all kinds of materials, leaving hundreds of thousands like this.

　　The rest of the money, in Liu Youdi’s view, can’t do any big business. She was too embarrassed to talk to her boyfriend again, so she turned to her friend for help, so the other party found her a so-called crooked way to make money.

　　Criminal Liu Youdi:She told me to introduce you to a way to make money quickly. I asked her what it was, and she said selling drugs.

　　I was lucky enough not to plead guilty, but now I regret it.

　　Liu Youdi, who was not aware of the law, was persuaded by her friends and contacted her last family, Chen Mou. She drove to Shanwei the day before the murder, bought methamphetamine from Chen Mou and returned to Guangzhou overnight, and then prepared to help sell it through her friends, but she was not expected to be arrested by the police soon. In court, Liu Youdi insisted on not pleading guilty with luck, but now, facing the prosecutor, she regrets her original choice very much.

　　Criminal Liu Youdi:I really regret not pleading guilty at that time. At that time, I still stood very hard. I really regret that at that time, including the presiding judge, including giving me this opportunity to speak my mind, just tell me that you can plead guilty and get this lighter punishment.

　　With Liu Youdi’s own confession of the crime, this drug case, which has gone through nearly four years and seven sessions, has finally come to an end, and the protest of this case is precisely that the procuratorial organ resolutely performs its legal supervision function and strives to make the people feel fair and just in every judicial case.

　　Shen Bingyou, Director of the Second Procuratorial Department of Guangdong Provincial People’s Procuratorate:If there is a mistake, it must be corrected. This mistake includes not only that those who should not be convicted are convicted, but also that those who should be convicted are not convicted. This mistake must be corrected is two-way, not simply one-sided understanding. Because fighting crime and protecting human rights are the dual responsibilities of procuratorial organs, and both are indispensable.

Cctv news(Reporter Han Fei): From October 23 to 28, the theme interview activity of "High-quality Development Research Bank" was held in Guizhou.

Guofa [2022] No.2 document stands in the national development pattern and clearly supports Guizhou to build six industrial bases, including new energy power batteries and materials research and development production bases. From October 23rd to 24th, the "High-quality Development Investigation Bank" went to Kaiyang County, Guiyang City, Fuquan City and Weng ‘an County, Qiannan Prefecture, to investigate the development of new industrialization.

Take the initiative to seize the development opportunity of new energy industry and promote industrial transformation and upgrading

Anda Science and Technology Energy Co., Ltd., located in Kaiyang County, Guiyang City, was a traditional phosphorus chemical enterprise when it was established in 1996. It mainly relied on the abundant local phosphorus resources, but its production energy consumption was high, pollution was high and the added value of products was low. With the arrival of the new energy industry outlet, the company took the initiative to seek a breakthrough in transformation, and began to focus on the research and development of cathode materials in Ferrous lithium phosphate in 2009. In 2011, Anda’s battery-grade iron phosphate was industrialized, and Anda became the main national supplier of cathode material precursors for BYD lithium batteries.

Anda Company attaches great importance to the investment in production and research, and promotes the continuous "hematopoietic" ability of enterprises through research and development. In recent years, Anda has introduced talents from top domestic scientific research institutions such as Peking University and Tsinghua, and invested more than 100 million yuan in R&D every year. At present, the company has obtained 66 patents, and has become an innovative enterprise integrating the research, development, production and sales of cathode materials for new energy lithium-ion batteries, lithium iron phosphate batteries and battery systems. In 2021, Anda Technology was awarded the title of "Specializing in Special New’ Little Giant’ Enterprise". In March 2023, Anda Technology became the first enterprise in Guizhou to land on the North Exchange. During the Tenth Five-Year Plan period, Anda’s new energy battery materials are expected to achieve an annual production capacity of 500,000 tons of Ferrous lithium phosphate and 500,000 tons of iron phosphate, with an estimated total output value of 52 billion yuan.

Despite many achievements, Liu Jianbo, chairman of Anda Technology, said in an interview that enterprises are still facing fierce external competition. Only by continuing to improve quality, reduce costs and increase efficiency and insisting on high-quality development can enterprises continue to maintain their development advantages.

"Project is king" to accelerate the construction of 100 billion-level industrial parks

In recent years, Fuquan City, Qiannan Prefecture insists on taking new industrialization as the first traction, highlighting the party’s organizational advantages in the effectiveness of industrial development and the speed of project construction, creating a 100 billion-level industrial park with vertical chains and horizontal groups, and running out of the acceleration of high-quality development of new industrialization.

Hunan Yuneng Company is a major supplier of cathode materials for lithium ion batteries in China. Fuquan City "grabs the speed" to introduce large projects and land large projects. In 2021, Fuquan City attracted Hunan Yuneng to build a new production base and set up Guizhou Yuneng. The Ferrous lithium phosphate production line project with an annual output of 150,000 tons in Guizhou Yuneng Phase I took only six months from leveling to commissioning, setting a record for the construction speed of major projects in Fuquan City. By the end of August, 2023, the second phase of Yuneng, with an annual output of 200,000 tons of iron phosphate and its supporting phosphorus chemical projects, and eight precursor production lines in Ferrous lithium phosphate have all been put into trial operation. The third phase of the project with an annual output of 150,000 tons of Ferrous lithium phosphate and 100,000 tons of iron phosphate is undergoing equipment installation and debugging.

Landing quickly and achieving good results. In 2022, Yuneng New Energy Project achieved an output value of 7.04 billion yuan, accounting for 19.8% of the total industrial output value of Fuquan City in that year. In other words, for every industrial output value of 5 yuan in Fuquan, 1 yuan comes from Yuneng, Guizhou.

Shenzhen Shengtun Group Laifuquan Factory is also one of the big projects introduced by Fuquan City in recent years. Guizhou Shengtun new energy project has an investment of 6.19 billion yuan and a planned land area of more than 1,200 mu, which will be built in two phases.

The first phase of the project with an annual output of 150,000 tons of battery-grade nickel sulfate, 20,000 tons of high-grade nickel matte and comprehensive recovery of gold, silver, platinum and palladium was put into production in August 2023. With the support of Fuquan City, the project construction period has been shortened by more than 50%. The second phase of the project includes a new energy material production line with an annual output of 300,000 tons of battery-grade iron phosphate, 150,000 tons of battery-grade nickel sulfate and 10,000 tons of metal-grade battery-grade cobalt products, which is expected to be completed by the end of 2024. After the completion of the two projects, it is estimated that the annual output value will be more than 20 billion yuan, which will drive more than 2,000 jobs.

In 2023, based on the advantages of industrial cluster development, Fuquan introduced Xiamen Xiamen Xiamen Tungsten New Energy Materials Co., Ltd. around Shengtun Phase II Project, and jointly established Fuquan Xiamen Tungsten 100,000 tons of Ni-Co-Mn ternary precursor project with Shengtun.

High quality promotes the rapid landing of the project and lays a solid foundation for the enterprise cluster to take root in Fuquan and long-term development.

High-quality service makes enterprises willing to stay.

Guizhou Yayou New Materials Co., Ltd. is the first major project of new battery materials introduced from Weng ‘an County, Qiannan Prefecture, and its capital injection enterprise is Hunan Yacheng New Energy Co., Ltd. Guizhou Yayou Phase I project with an annual output of 100,000 tons of iron phosphate with an investment of 1.2 billion yuan was completed and put into operation at the end of 2022, and the cumulative output value in the first three quarters of 2023 was 280 million yuan. The second phase plans to invest 4.6 billion yuan, covering an area of 1,300 mu, mainly building a 200,000-ton iron phosphate production line, etc. It is planned to be completed and put into operation in the second half of 2025. In the future, the production capacity of Yayou in Guizhou will be four times that of the headquarters base.

Under the double blessing of the advantages of resources and industrial clusters, Weng ‘an County has taken the initiative to provide good services and effectively reduce the burden on enterprises. Because the phosphate rock resources declared by Yayou Company in the early stage can not meet the allocation conditions in a short time, it affects the production cost and market competitiveness of the enterprise in the later stage. At the same time when the enterprise declares new phosphate resources, Weng ‘an County has sold the output of 5% equity of the county platform company in Weng ‘an Phosphating Company to Yayou Company at the mining price in exchange for raw materials such as battery-grade ammonium hydrogen phosphate and industrial-grade phosphoric acid. This measure has solved the urgent need for enterprises to produce and use mines, and reduced the cost for enterprises. In addition, Weng ‘an County also gives corresponding support to enterprises in terms of electricity, water and gas security, and solves the difficulties of enterprises one by one in time, so that enterprises can develop more safely in Weng ‘an.

Guizhou is making efforts to optimize the industrial layout and build a development pattern of "one core and two regions". As a "one core", Guiyang Gui ‘an and Kaiyang Xifeng and Weng ‘an Fuquan are taking the phosphorus chemical industry base as the core, cultivating and building new energy batteries and supporting industrial clusters, and promoting the quality improvement of new energy batteries and materials industries.

　　Jiang Huasong, who is 54 years old and has been teaching for 33 years, was finally awarded a professor not long ago.

　　Different from the well-known "in the evaluation of university titles, scientific research achievements and the number of papers are the most important", the teacher of Science College of Nanjing Forestry University, who has been an associate professor for 12 years, opened the door to "professor" with "no paper, no scientific research, all relying on the performance and achievements of classroom teaching at ordinary times".

　　Today, colleges and universities in China are generally criticized for "emphasizing scientific research over teaching". This incident was interpreted by the media as "you can be a professor without a paper" and quickly boarded a hot search. Many netizens, teachers and scholars praised the title evaluation policy of Nanlinda University, believing that classified evaluation and giving full play to talents can promote the improvement of teaching quality in colleges and universities, change the argument that "teaching well is better than writing well" and "open up a new channel for the evaluation of professional titles in colleges and universities" and "is the general trend".

　　But with the fermentation and spread of things, more doubts followed.

　　In the past few days, more than one teacher told reporters that teaching, scientific research and social service are the three major responsibilities of professors, and one of them cannot be neglected; Teaching without research is not deep, and teaching without scientific research does not conform to the law of the development of higher education today. Some scholars even bluntly said, "Comment on ‘ Teaching professor ’ It is misleading to the public. "

　　Why did this incident cause such a controversy in academic circles? The reporter interviewed college teachers in depth, truthfully reflected their voices and voices, and hoped that this would lead to more thoughts on the evaluation of college professional titles.

　　Argument 1 “What is a professor?

　　[Reporter’s observation]: The reason why "you don’t need a paper to judge a professor" causes controversy lies in the different understanding of the word "professor". Wang Hao, president of Nanlin University, said that this initiative was launched because "the most important task of a university is to teach and educate people. Scientific research is important, but it is more important to let teachers return to their teaching duties". This has attracted a lot of spit: "Professor" is originally an academic title, and it is not a professor without doing research.

　　What is "professor"? Can only good teaching be qualified as a university professor?

　　● Positive: Teachers should return to their teaching duties.

　　Chen Feng (pseudonym), a lecturer at a university in Shanxi:

　　I am a university teacher who teaches public courses, and I like the professional title evaluation regulations of "teaching professor" in Nanlin University.

　　Since I first joined the company, I have been constantly reminded by "experienced people" that teaching is a conscientious job, and class is almost enough. The key is to hand out enough papers. For a long time, the evaluation of professional titles in domestic colleges and universities is mostly based on scientific research results, and teaching only needs to complete the class hours. Influenced by this "baton", many teachers spend most of their energy on scientific research, but only regard teaching as a "public task". "Teaching is better than writing well" and "Scientific research is a private land and teaching is a public field" are also circulating in colleges and universities. Especially for basic courses such as mathematics and foreign languages, teachers have taken on a lot of teaching tasks, so it is difficult to have leisure time to study scientific research. In addition, what was originally taught was some classical theoretical knowledge systems, so it was difficult to make a breakthrough in scientific research. Over time, the kung fu of scientific research was left behind.

　　Teaching and educating people is the greatest duty of teachers, and it needs to be emphasized today. In recent years, in addition to professional title evaluation, many universities have also introduced teaching bonuses, which is a good signal. Only by making it easier for those teachers who devote themselves to teaching and specialize in teaching to promote their professional titles can we stimulate the enthusiasm of the teaching staff to the maximum extent and promote the resonance of teaching and scientific research at the same frequency. This is the general trend and the aspiration of the people.

　　○ Against: University professors must engage in scientific research.

　　Wu Zunmin, a professor at East China Normal University:

　　It is simply unreasonable to "evaluate professors without a paper". University professors must engage in scientific research, and they can evaluate "senior lecturers" only by giving lectures without research, but they must never evaluate professors.

　　It is undeniable that teaching is one of the basic responsibilities of university teachers, and attending classes is the basic skill of university professors. However, as the highest academic title of a university, "professor" has only one standard in the world, that is, not only to teach first-class, but also to conduct profound scientific research and lead growth — — Teaching, scientific research and service are the three major responsibilities of professors, and any emphasis on one of them while ignoring the others will lower the standards of professors.

　　"Professor" comes from Latin, which originally means an expert in the field of art and science, and now it is the highest academic title in colleges and universities in the world. Its implication is simple, that is, in colleges and universities, the primary task of professors is to engage in innovative research in their respective disciplines and offer courses for undergraduate and graduate students. Compared with lecturers and associate professors, professors have more important significance in their leading role, having profound insights into the research frontiers and existing problems of the discipline, reflecting the pursuit of profound knowledge and leading the development direction of the discipline. Only in this way can professors play their due role and truly lead the growth of students and young teachers.

　　Of course, I’m not denying that the professor has to attend classes. Today, what we want to advocate is that professors should lead the team of teachers to improve the teaching ability, academic level and team spirit of young people. My ideal is such a state: the basic courses of undergraduates can be mainly undertaken by lecturers and associate professors, and guided by professors; The courses for postgraduate students are undertaken by associate professors and the courses for doctoral students are undertaken by professors, thus forming a three-level structure, in which lecturers are trained, associate professors are the link between the preceding and the following, and professors lead, which will not affect the scientific research level of colleges and universities and will not "kill the professors".

　　Debate 2: Are teaching and research complementary or mutually exclusive?

　　[Reporter’s observation]: What is implied in the debate about "what is a professor" is actually a dispute over the relationship between teaching and scientific research. In recent years, the call for professors to teach undergraduate students is deafening, and the debate about whether universities should focus on scientific research or teaching is heated up. During the interview, more than one teacher complained to reporters that too many class hours made him too busy for scientific research; Some teachers also believe that teaching will distract their scientific research energy and they can only "choose what is more important for their own development". But there are also many people who believe that without academic research, one’s teaching cannot achieve Excellence; "Teaching without scientific research is an education without views and soul".

　　How to treat teaching and scientific research? Are teaching and research complementary or mutually exclusive?

　　● Positive: Teachers’ energy is limited, and "teaching" will inevitably lead to "scientific research".

　　Tommy (pseudonym), a lecturer at a university in Beijing:

　　I don’t think scientific research and teaching have a particularly direct relationship in a sense. It must be admitted that there are differences between different teachers, some are good at teaching, some are good at scientific research, and a few people can go hand in hand with teaching and scientific research. In my growing experience, many times a good teacher is not a good researcher, and a good researcher’s evaluation score is very low.

　　There are examples. A previous survey on the School of Business and Economics of Maastricht University showed that in the undergraduate stage, the teaching of top researchers can’t improve the performance of undergraduates, and the role of these scholars will only be reflected in the postgraduate courses. From the feedback of students, they will not give these top researchers higher teaching evaluation scores. Even many undergraduate students give the best researchers in the school a score lower than the average of the school.

　　There are two reasons for this: First, compared with basic research, teaching is a completely different skill. The former needs to study, while the latter needs to learn from others, need special teaching skills and methods, establish close relationships with students, etc. Few people have the same excellent quality in scientific research and teaching; Second, the existing orientation makes teachers often "pay more attention to scientific research than teaching" — — "No time for scientific research" has become the most common state around me, and many teachers are unwilling to participate in teaching evaluation activities. "All-staff scientific research" is the truest portrayal of China University.

　　Teachers’ energy is limited, and "teaching" is bound to lose "scientific research". Therefore, I think it is necessary to set up two professional title evaluation and employment systems, namely, "research professor" and "teaching professor", so that every teacher can find his own development space and get treatment that matches his value.

　　○ Counterparty: Teaching without the guidance of scientific research ideas cannot be regarded as "university teaching".

　　Guo Yingjian, a professor at Renmin University of China:

　　At present, there are many misunderstandings or misunderstandings about the relationship between teaching and scientific research in universities in China. The first is to treat teaching and scientific research in opposition. But in fact, in the world, all kinds of colleges and universities have put forward much higher requirements for the scientific research of "professors". Teaching without the guidance of scientific research ideas cannot be regarded as "university teaching".

　　In the United States, even teaching-oriented liberal arts colleges pay more and more attention to teachers’ scientific research ability and the publication of their achievements. In May 2014, Academy, the publication of American Association of University Professors, published a research result, which showed that scientific research and the publication of teachers’ scientific research results played an increasingly important role in teachers’ evaluation, even in teaching-centered liberal arts colleges. These researchers choose four-year colleges of arts and sciences because these universities generally focus on teaching, while those research universities pay more attention to research and publication.

　　Scientific research promotes teaching, which is not only conducive to teachers’ innovative teaching, but also conducive to the cultivation of students’ critical thinking. It has been suggested that the times are changing rapidly, and only those teachers who are engaged in academic research have the ability to acquire and exchange the latest knowledge with students. As far as teachers are concerned, only research-oriented teachers can better choose the content of lectures, know what important topics and concepts to choose, and spread knowledge to students in a more appropriate way. Many foreign universities believe that academic research by teachers is also attractive to students. Students’ participation in scientific research or academic research has become the norm of undergraduate education in many foreign universities.

　　Debate 3: Can professors "rule by type"?

　　[Reporter’s observation]: In fact, Nanlinda is not the first person to "eat crabs". As early as ten years ago, "teaching professors" entered the institutional level of domestic universities one after another. In this regard, some commentators believe that "teaching-oriented professor" is conducive to solving the imbalance between scientific research and teaching, to the selection of university talents and the optimal allocation of human resources, and to the formation of school-running characteristics of universities according to their own characteristics. However, some people object that university professors cannot be "governed by different types" and that "teaching-oriented professors" are subjective fabrications that do not conform to the law of higher education development.

　　● Pro: "Teaching-oriented professor" redefines "academic"

　　Professor Li Qi of Beijing Normal University:

　　Since the end of World War II, in many countries with developed higher education, the attention paid to scientific research has far exceeded the attention paid to teaching, and even had a negative impact on the fundamental mission of talent training in colleges and universities. In this context, developed countries, led by the United States, began to reaffirm the core mission of teaching. Among them, Ernest Boyer wrote in Academic Reflection — — The report "Priority of Teaching Work" puts forward that "academic" should be redefined, and the new "academic" should contain four interrelated aspects, including "discovery, synthesis, application and teaching". To some extent, this academic idea reconciled the contradiction between scientific research and teaching, and also integrated them together. As a matter of fact, as long as university administrators allow, professors can choose one of the above four disciplines in teaching, scientific research and social services, develop relevant literacy, and thus become qualified professors.

　　It can be imagined that even if there is no "teaching professor", the main responsibility of teachers should be teaching in teaching-oriented colleges whose core mission is teaching. But this does not necessarily mean that teachers in teaching-oriented colleges do not need to carry out scientific research. Under the new definition of "academic", what to teach, how to teach, who will teach and who will learn are teaching problems that need to be studied, and they are professional problems. However, under the current college environment and professional title evaluation system, these problems have become management problems. Only by reducing management problems to professional problems, allowing teachers to solve specific professional problems through school-based research and guiding teachers to participate in school-based teaching research and evaluation can we achieve the goal of encouraging teachers to continuously improve teaching quality.

　　○ Counterparty: "Teaching-oriented professor" can only be "the product of historical transition period"

　　Guo Yingjian, a professor at Renmin University of China:

　　"Teaching-oriented professor" is only a product of the transitional period, and discussions like this and their topics — — That is, "can you judge a professor without a paper?" It’s just a transitional topic. Because this is actually a problem left over from history, that is, there are some (even a large number of) scholars born after 50, 60 or even 70. Before or after they entered colleges and universities, they did not study for a doctorate or the highest degree in related industries because of historical or personal reasons, because they did not pay enough attention to scientific research because of their biased understanding, or they were not interested in scientific research, or their scientific research ability was limited. Some of them hardly engaged in scientific research, but their teaching level was very high. However, this phenomenon will hardly appear again in the process of the growth of scholars after 75 and 80 — — Because they don’t have a doctor’s degree or the highest degree in related industries, they don’t have strict academic research training, and they don’t have corresponding scientific research results, so they can’t enter colleges and universities at all.

　　Personally, I think that university professors can’t "rule by type". In my opinion, universities can’t have professors who only teach and don’t do scientific research, nor can they have professors who only do scientific research and don’t engage in teaching — — It’s interesting that this type of professor exists in many colleges and universities now, but it is rarely discussed. The reason is very simple, the responsibility of the title of professor — — Teaching, scientific research and service should be indispensable. The "teaching-oriented professor" implemented in China universities at present is an expedient measure to solve the problems left over from history, and it is believed that it will gradually disappear in the future, which is not the "general trend".

　　Argument 4 “How to evaluate "excellent teaching ability"

　　[Reporter’s observation]: Among many debates, there is also a focus on how to evaluate "teaching Excellence". According to reports, there are two evaluation dimensions in the selection of "teaching professors" by Nanlin University: teacher-student evaluation and classroom quality expert evaluation. The evaluation of teachers and students is made up of the data collected by the school’s student affairs office from the graduates’ teaching activities in the past five years. The expert evaluation of classroom quality is conducted by the Academic Affairs Office, without teachers’ knowledge, by randomly grabbing three 45-minute teaching videos from the previous year’s teaching videos, and organizing at least three national or provincial-level teaching masters outside the school, as well as on-campus teaching supervision, etc. In this regard, some people think that this is a return to the initial heart and origin of teaching, giving the right to judge to students and peers; However, it has also been pointed out that "teaching Excellence" should be reflected in its popularization and reproducibility, rather than just being decided by the students in their own classes.

　　● Positive: Teaching should speak with classroom quality.

　　Chu Zhaohui, a researcher at China Academy of Educational Sciences:

　　At the present stage of development of universities in China, I think it is necessary to evaluate some teaching-oriented professors, and the key issue is how to evaluate them. At present, colleges and universities have not reached a consensus, but it must be recognized that teaching-oriented professors cannot be regarded as "professors with low scientific research level" and "professors who do not write papers", or they need to be evaluated from their functions.

　　In this regard, the practice of Nanlin University is still good. The core essence is that teaching should speak with classroom quality, especially by adding the link of attending lectures or watching teaching videos, and inviting national or provincial famous teachers and school supervisors to comment, which can effectively ensure that people who are really good at teaching can be screened out.

　　However, I think it is necessary to clearly distinguish the boundary between student evaluation and teacher evaluation, and use teacher-student evaluation scientifically: due to the limitation of students’ knowledge level, student evaluation is more about evaluating teachers’ attitude and their own learning feelings, rather than teachers’ professional level; Teachers and experts should pay more attention to professional evaluation, and ensure that authoritative experts generally recognized by teachers form a third-party evaluation agency to maintain the authority and credibility of the system.

　　○ Counterparty: "Excellent teaching ability", and the bottom line of scientific research cannot be broken.

　　Tang Bin, Associate Professor of Southwest University:

　　I don’t think that public teachers don’t have the time and space to do scientific research, and "teaching professors" don’t need to issue papers. Students and peers are indispensable for the evaluation of "excellent teaching ability", but the evaluation of professors must have a considerable level of scientific research, and this bottom line cannot be broken.

　　From my own experience, I feel that scientific research and teaching are "separated" in the first two years. At this stage, a lot of time is spent in the process of preparing lessons, getting familiar with teaching materials, making courseware, and repeatedly modifying teaching design. There is not much real scientific research. But after this stage, you will find that the existing knowledge reserve, teaching methods and teaching design can’t meet the requirements of high-quality courses, but can only say that the knowledge is spoken out. From then on, scientific research and teaching have interacted and started to promote each other — — To teach a course well, teachers need to constantly delve into problems and break through the original knowledge pattern, which will form a process of "looking for scientific research in teaching and feeding back teaching with the results of scientific research or phased results".

　　Therefore, I think that the current evaluation dimension of "excellent teaching ability" is more important than not losing scientific research, but this kind of scientific research can be more reflected in teaching research, as well as the replicability, popularization and influence of teaching experience, such as publishing teaching reform papers, participating in teaching reform projects, and obtaining teaching results.

　　Debate 5: Can the teaching indicators of different levels and types of universities be different?

　　[Reporter’s observation]: As of June this year, there were 2,956 institutions of higher learning in China. During the interview, some teachers said that more than 2,000 universities should be divided into levels and functions, and China does not need so many research universities. In non-research universities, professional title evaluation should pay more attention to teaching or achievement transformation; In this regard, some people also expressed strong opposition, saying that no matter what type or level of colleges and universities, the scientific research skills of "professors" must not be lost.

　　Can the evaluation index and orientation of professional titles in different levels and types of universities be different?

　　● Positive: The evaluation of professional titles should move from "a ruler" to distinctive and differentiated.

　　Li Huadong (pseudonym), a staff member of the Personnel Department of a university in Jiangsu;

　　My college is a national demonstrative higher vocational college. I think that the evaluation criteria of professional titles in different levels and types of colleges and universities are different, and we can’t "measure everything with one ruler" but have characteristics and differences.

　　In Jiangsu, in fact, many colleges and universities have started reforms like Nanlin University. On the basis of fully considering the diversity of teachers, all colleges and universities have formulated professional title evaluation methods that are suitable for the actual situation of teachers in each school according to the differences in disciplines and types. As we evaluate professors in vocational colleges, we should pay more attention to the classroom effect, social contribution, the effectiveness of the transformation of achievements, or even more, instead of judging heroes by scientific research achievements, as in research universities such as Peking University and Tsinghua.

　　○ Counterparty: Teaching, scientific research and social services, the "three brushes" of professors must not be lost.

　　Cheng Fangping, a professor at Renmin University of China:

　　I think that no matter what type and level of colleges and universities, the orientation of professor evaluation is the same, that is, teaching, scientific research and social service can not be lost. Only in different levels and types of colleges and universities, the specific indicators or manifestations of the above three points are different.

　　The first thing in university education is to teach professionally, the second is to explore unknown fields, and the third is to serve the society, regardless of ancient and modern times. Therefore, even in some application-oriented universities, teachers also need scientific research to study how to explore and spread outside the teaching materials. It’s just that there are academic research, practical research and practical research, and research-oriented and applied universities have their own research paths. Some of these are new discoveries and inventions, and some are the transformation of existing achievements, but this must not be ignored because of the different types and levels of universities. It should also be noted that today, we can not only emphasize that teaching-oriented teachers should attach importance to scientific research, but also emphasize that teachers who are good at research should attach importance to the improvement of teaching methods, and they can have different weights in different series of evaluation and employment standards, but teaching and scientific research must be evaluation dimensions and are indispensable.

　　(Reporter Deng Hui)

　　BEIJING, May 14 (Xinhua) Wang Yeqiang, an associate researcher at the China Academy of Social Sciences, said today that overall, 2018 will be the low point of this round of real estate market, and the overall real estate market will show a downward trend. Affected by the decline in sales, it is expected that the real estate market price will maintain a steady decline in 2018. First-tier hotspots and second-tier cities may take the lead in bottoming out, while third-and fourth-tier cities still maintain a certain degree of heat. It is expected that there may be a big correction in the third-and fourth-tier cities in the second half of 2018.

　　Data Map: Real estate development projects.

　　China Academy of Social Sciences held the 2018 China Real Estate Summit Forum and the "Blue Book of Real Estate" conference on the morning of May 14th. Associate researcher Wang Yeqiang, executive editor of the book, introduced the relevant situation.

　　Wang Yeqiang looks forward to the rental and sale of real estate market in 2018. He said that from different markets, the change of land price in 2018 will be based on a moderate increase, and the price mechanism of the real estate market will be accelerated, while the task of first-line risk prevention and control is still arduous, and changes in third-and fourth-tier cities must be paid attention to. At the same time, the third and fourth lines are mainly characterized by structural contradictions, which should be based on stability. At the same time, we should pay close attention to the market dynamics and strictly prevent and control the price signals that may appear in a few cities when investment demand disturbs the market.

　　The establishment of supply systems and modes suitable for emerging industries and new formats will help the smooth operation of the industrial land market, and the market demand and land price of industrial land will be affected by the development of emerging industries. Actively exploring the supply systems and modes of emerging industrial land will help the smooth operation of the industrial land market.

　　(II) From the perspective of the personal housing credit market, it is predicted that the regulation policy of the real estate market will remain stable in 2018, and the urban policies with overheated momentum will be tightened. On the whole, the real estate market will enter an adjustment period after a sharp rise in the past few years, and the growth of personal housing loan business will also slow down. At the same time, the loan interest rate will continue to rise under the impetus of rising marketization costs. From the perspective of regulatory policies, it should be the trend of maintaining overall stability.

　　In the short term, in order to achieve the expected effect of stabilizing the market, the relevant short-term restrictive policies will not be relaxed and withdrawn. In the long term, it is necessary to further improve policies such as land supply, simultaneous rental and sales, and real estate regulation and control, and gradually replace short-term regulatory policies such as restricting purchases and loans. From the perspective of the growth rate of personal loans, the growth rate will continue to slow down. Due to the continuous decline in the sales area at the demand level and the tightening of the superimposed loan restriction policy, the overall demand for personal housing loans will shrink. From the perspective of supply, the increment and structure of personal housing loans will be subject to unified supervision, and the demand for corporate credit will obviously pick up, which will further affect the supply of mortgage funds.

　　At the same time, there is still room for further increase in the interest rate of personal housing credit. Some foreign economies are tightening the provision policy, including the business of raising interest rates and shrinking the table in the United States, which also has a certain impact on our national monetary policy. At the same time, the credit demand of the enterprise sector will pick up, and the tight credit scale will be maintained, which may promote the personal housing loan to continue to rise.

　　(3) Investment and financing are mainly affected. One is the major changes in the real estate market. For example, land auctions introduce mechanisms such as self-sustaining, competitive matching and lottery auction. Second, restrictions on purchases, loans, sales and business in the real estate market have become the mainstream regulation methods in large and medium-sized cities. Third, there is a large supply of shared property rights and rental housing. Judging from the trend of real estate investment, the investment keeps moderate downward trend, and the investment structure may be further adjusted. It is expected that the real estate investment will enter the downward channel in 2018, and the decline may be accelerated in the future from the moderate downward trend, and the investment structure is facing major adjustment. In the financing business, it is the primary task to be stable and tight, and to prevent risks.

　　(4) From the perspective of the residential market, one is that the residential sales area has further decreased. As the amount of shantytown renovation in 2018 will be less than that in 2017, it means that the resettlement of shed reform has a great impact on housing sales, especially in third-and fourth-tier cities, and this positive pulling effect will gradually decline. Second, the growth rate of housing development investment has declined, and it is expected that the growth rate of development investment will also decline in 2018. Considering the continuous increase of newly started area and the rapid increase of land price in the past two years, it is estimated that the growth rate of development investment will remain at around 5% throughout the year. The housing price is stable and declining. From the perspective of the real estate boom cycle, a series of indicators in the real estate market show that the market has entered a stage of downturn, and the market has an internal driving force for downward adjustment. It is expected that the housing market will also show the characteristics of periodic downward adjustment in 2018, and the housing price is likely to be stable and declining.

　　(V) Overall judgment, our overall judgment on China real estate in 2018 shows that 2018 will be the low point of this round of real estate market, and the overall real estate market will show a downward trend. In the supply-side first-line and hot-spot second-tier cities, in order to alleviate the inventory crisis, the land supply is expected to increase further, but it is difficult to relax the price limit policy, the supply in hot cities will continue to be tight, the policy base for real estate regulation and control on the demand side will not change, and the tightening of bank credit will also significantly increase the cost of buying houses, so the transaction scale will also be limited to some extent, and the sales area of commercial housing will be adjusted back due to the dual effects of regulatory policies and monetary environment. Shrinking sales and blocked financing channels will put financial pressure on housing enterprises and affect their willingness to start work to a certain extent, and the growth rate of new construction will continue to run at a low level.

　　Wang Yeqiang said that because the property market regulation policy is not relaxed in 2018, unfavorable factors at all levels of demand policy still exist, and corporate financing is blocked, and residents’ deleveraging development loans are tightened, which will have a negative impact on the growth rate of development investment in 2018. It is expected that the development investment in 2018 will remain at a low level, and there may be a slight rebound in the first half of the year. In the second half of the year, we think it should continue to maintain a legitimate downward trend, and it is difficult to have a strong performance throughout the year. Due to the decline in sales, it is expected that the development investment in 2018 will continue to

　　From the perspective of different cities, because the real estate control policy is not relaxed, first-tier hotspots and second-tier cities may take the lead in bottoming out. The adjustment of third-and fourth-tier cities obviously lags behind that of first-tier cities. Due to the relatively loose current policies, the spillover of demand and the support of shed reform policies and monetization policies, third-and fourth-tier cities still maintain a certain degree of enthusiasm.

　　With the gradual withdrawal of the destocking stimulus policy and the tightening regulation, it is expected that there may be a big correction in the third-and fourth-tier cities in the second half of 2018.

　　Wang Yeqiang said that we should have the following four trends in the real estate market in 2018. First, the relationship between supply and demand may be fundamentally reversed in 2018. In addition to the direct demand for housing, at the same time, due to the central control policy of staying and not speculating, it will have a greater impact on market expectations. At the same time, the toughness of development investment will increase significantly, because the start of sales by real estate enterprises means a loss, so real estate enterprises may deliberately lengthen the development cycle. At the same time, the capital level will affect the willingness of developers to take land, and the residential price index will maintain a decline throughout the year.

　　Recently, hundreds of residents in a residential area in Yuci District, Jinzhong, Shanxi Province have concentrated symptoms such as vomiting and diarrhea. The local health and sports bureau reported that some patients in the community had detected norovirus type II.

　　October to March is the high season of norovirus infection. Recently, many hospitals in China have also received some patients with vomiting and diarrhea in outpatient and emergency departments, and were diagnosed with norovirus infection.

　　Infected with norovirus, what are the symptoms?

　　Norovirus belongs to calicivirus family, which is one of the common pathogens causing acute gastroenteritis. It has the characteristics of low infection dose, long detoxification time and strong external environmental resistance. The whole population is generally susceptible, and it is easy to cause outbreaks and epidemics in schools, kindergartens, nursing homes and other crowd gathering places. Because its high incidence time is mostly in winter and spring, it has obvious seasonality, and people often call it "winter vomiting disease".

　　Norovirus has a short incubation period, usually 24-48 hours. The main symptoms after infection are nausea, vomiting, abdominal pain, diarrhea and other acute gastroenteritis symptoms, and some patients will have headache, chills and muscle aches. Children often vomit after being infected with norovirus, which may cause dehydration symptoms; Adults have diarrhea, and the feces are watery or watery.

　　In addition, norovirus spreads in various ways. It is often transmitted through respiratory tract, digestive tract and contact, such as eating food contaminated by norovirus, patient’s feces or vomit, inhaling aerosol generated by vomit, or contaminated object surface.

　　Without specific medicine, how to prevent and treat it?

　　Norovirus gastroenteritis is an acute viral infectious disease with self-limitation, and there is no specific antiviral drug at present, so symptomatic treatment is mainly adopted for this kind of disease.

　　Most patients have mild symptoms after onset, generally lasting for 2-3 days, and no treatment is needed. In severe cases, mild and moderate dehydration symptoms can be supplemented with water and electrolyte consumed by vomiting and diarrhea through oral sugar saline or oral rehydration salt. For infants, the elderly, especially those with basic diseases, if they have serious symptoms such as dehydration and persistent high fever due to frequent vomiting or diarrhea, they should seek medical treatment in time.

　　The key to norovirus infection is to prevent it. In the period of high incidence of norovirus infection, we should try to reduce going out, pay attention to hand hygiene, thoroughly wash our hands before and after meals, steam food before eating, and do not drink raw water; At the same time, strengthen exercise and improve your immunity; Do a good job in environmental cleaning and disinfection, and use chlorine-containing disinfectants to clean and spray pollutants and polluted places, and regularly open windows for ventilation; In addition, after being infected with norovirus, patients should rest at home until 3 days after recovery before going to school or working to avoid infecting others.

Attachment: Information of 53 batches of unqualified cosmetics

Since ancient times, heroes have produced teenagers. In history, we have seen countless talented teenagers invent various theories, methods, technologies and products that change the world.

Today, teenagers with unlimited imagination and creativity are also changing the world with their own inventions.

Looking at their inventions, some can bring new impetus to the transformation of an industry, while others hope to save the lives of a group. But all roads lead to the same goal, and their inventions are put forward because they see the existence of a certain problem and want to change and solve it.

Of course, behind their inventions, we should pay more attention to what kind of education and environment can provide fertile ground for teenagers to give full play to their imagination and creativity. What should we do to naturally shape this kind of education and environment.

After all, young people are strong, and technology is strong; Youth is strong, then the country is strong.

1. Ionic liquids for industrial carbon capture.

CO2 is one of the most important greenhouse gases, but it is also a rich resource. At present, some organic solvents are commonly used in industrial production to absorb CO2, but it is difficult to release CO2 again, and it is easy to corrode industrial equipment.

In September, 2017, Zhao Songrui, who is already a freshman in the School of Chemistry and Molecular Engineering of Peking University, won the special prize of the European Association of Chemistry and Molecular Sciences for his "Study on the Synthesis and Characterization of Pyridine Ionic Liquids and CO2 Absorption Performance", which achieved a zero breakthrough for Chinese players in the EU Young Scientists Competition.

The pyridine ionic liquids studied by Zhao Songrui can quickly attract and release CO2, and the stability is very good. This technology has a broad application prospect in the field of industrial carbon capture.

2. Ultra-efficient catalyst converts plastic waste into biofuel.

AzzaAbdelHamidFaiad, an Egyptian girl, found a cheap catalyst at the age of 16, which can quickly and continuously convert plastic waste into biofuel.

Faiad successfully decomposed waste plastics into methane, propane and ethane by using calcium-based bentonite as catalyst, and then converted it into ethanol for fuel use.

The process can produce as much as 138,000 tons of hydrocarbon gas every year, and generate biofuels worth 78 million dollars. Egypt produces about 1 million tons of waste plastics every year, which is helpful to Egypt’s environmental protection and economic development.

She won the prize of European Nuclear Fusion Development Agreement (EFDA) in the 23rd European Union Young Scientists Competition, and attracted the attention of Egyptian Petroleum Research Institute.

3. Life-saving building fire smoke mask system

In 2013, AlexisLewis, an American girl, heard a mother throw a 2-year-old child from the second floor to avoid the harm caused by fire smoke to the child, which led to the idea of designing a smoke mask.

In order to save the people trapped in the building by the fire, Lewis found in the experiment that the success rate of directly throwing the smoke mask into the room from the window was very low, so he designed several 3D printed bomb prototypes and installed a light smoke mask produced by XcaperIndustries, a professional respiratory protection equipment manufacturer, in the bomb.

After more than 290 tests by 37 firefighters throwing bullets at the second floor window, the rugby-type bullets with throwing accuracy exceeding 70% were finally determined.

The design can provide a safe breathing mask for those who encounter fire and have no time to escape, which effectively protects the lives of residents.

Lewis was only 15 years old when he designed the smoke mask system, and he had many patent inventions.

4. Using algae to convert CO2 from automobile exhaust into oxygen.

In 2008, ParamJaggi, a 16-year-old American boy, began to pay attention to automobile exhaust emissions while learning to drive. He designed an exhaust purifier using seaweed, which can reduce carbon dioxide in automobile exhaust.

With this invention, he won a prize of 8,000 dollars and a sustainable development award from the US Environmental Protection Agency.

ParamJaggi has applied for a patent and set up a company. The first product developed by Paramjaggi, AlgaeMobile carbon filtration system, has built-in panels covered with special algae strains on both sides, and uses photosynthesis to absorb carbon dioxide emitted by automobiles to produce oxygen and glucose (for feeding algae).

Considering that automobile exhaust emissions are too fast, Jaggi arranges a plurality of panels in a staggered way to increase the contact surface area of carbon dioxide and melt carbon dioxide into water to form carbonic acid; Sodium hydroxide placed in the filter reacts with carbonic acid to form harmless carbonate.

ParamJaggi has won many honors and been included in Forbes’ list of 30 outstanding men under the age of 30 in American science and technology field.

5. Simple life-saving equipment in the car to prevent children from dying of heat.

Every year, many children around the world die of heat in cars for various reasons. In 2011, AndrewPelham, an 11-year-old American boy, came up with the concept of EZBabySaver when he heard that a 10-month-old baby was trapped in a car and died of heat.

Pelham’s invention is made of rubber sleeve and adhesive tape, which connects the handle in the front door of the car with the driver’s back seat, thus reminding parents to check the back seat before getting off the bus to prevent tragedy. With this invention, he won the runner-up in the Young Inventors Group in the Rubber Band Competition.

According to media reports, hundreds of parents and grandparents around the world told Pelham by email that they had made this simple baby protector. Although the attention of this small invention is limited, we have to admit that it is a very effective invention.

6. Low-cost Lego Braille printers

In 1824, Louis Blair, a 15-year-old French blind man, created French Braille to help countless blind people read.

In 2014, 13-year-old American boy ShubhamBanerjee used robot toys and programming technology to help the blind again.

Banerjee assembled a Braille printer Braigo using Lego EV3 set with a price of $350. The printer can print Braille with better recognition ability by updating the built-in software and enhancing the hardware.

The invention directly reduces the price of Braille printers on the market from 2000 dollars to 350 dollars. Banerjee has set up a laboratory, focusing on the research of low-cost Braille printing technology, and obtained the investment from Intel. The lab also developed "the world’s first low-cost/silent/on-chip translation /IOT-Cloud printer concept".

This invention helped Banerjee win the 2014 Technology Award and was invited to attend the WhiteHouseMakerFaire (Creative DIY Party) held in the White House.

7. Cheap and rapid Ebola detection

In 2015, OliviaHallisey, a 16-year-old American middle school student, invented a new Ebola virus detection technology.

The invention is based on the principle of chemical reaction. When Ebola virus in blood reacts with chemicals in the reagent, the reagent will change color. This method can complete the detection within 30 minutes.

In addition, the cost of each detection is only 25 dollars, and the storage and transportation of reagents do not need refrigeration.

This invention helped Hallisey win a $50,000 scholarship in the 2015 Google Science Challenge.
