Zero hundred, accelerate for 4.0s! On September 9th, Dading Lock Order was delivered on September 30th, and Weilai ET5 mirror powder was unveiled at the auto show.

With the arrival of this year’s Chengdu Auto Show, major car companies have begun to build momentum for their own heavy new cars. As the leader of the new force in car-making, Weilai ET5 mirror powder, a subsidiary of Weilai Automobile, appeared at this auto show. At present, a lot of information about this new car has been released. New carThe big lock order will be opened on September 9, and the first batch of new cars will be delivered on September 30.

What information did Weilai ET5 announce at this conference? Let me take a look:

"Olive" burst into flames, the legendary ceiling repair, how to choose?

Autumn and winter are coming, the climate is unstable, and it is time for sensitive muscle pain.

In daily life, excessive cleaning will be sensitive, and brush acid will also be sensitive if she is excessive, and sometimes she is sensitive even though she has done nothing.

In addition to repairing the skin wall (barrier), the nursing of sensitive muscles should also put out (suppress) the small fires (inflammatory factors) in the wall from time to time, otherwise, when the small fires become a prairie fire, it will cause thousands of miles of bare land (such as pigmentation and other problems).

Recently, there is an ingredient that is particularly hot-olive leaf extract, which claims to be a soothing and repairing "ceiling". What is the actual effect behind it? How can we choose so many related products? Today, I will take you through an article.

01

What is an olive?

First of all, let’s look at the olive leaf extract, which is actually not the same thing as the olive we eat every day, but the olive (Olea europaea) growing in the Mediterranean region, a famous subtropical fruit tree, which is a long-lived tree.

 

At present, olive leaf extract mainly has the following functions:

1 Soothes & reduces redness:

According to the data of Hallstar, a well-known raw material supplier, we can see that although it is inferior to dexamethasone (a synthetic corticosteroid), it also has a good inhibitory effect on the expression of IL-1α.

 

At the same time, from the data given by the supplier, we can see that 1% olive extract can improve the redness and oil secretion of acne muscle in 7 days, so the title of acne muscle mother is not random.

2 anti-oxidation:

Olive leaf extract contains high content of oleuropein (3%-18%), and oleuropein has been proved to have good antioxidant effect by many experiments. However, it should be noted that compared with the preventive effect (applied before being irradiated by ultraviolet rays), it has a better soothing effect (applied after being irradiated by ultraviolet rays).

Nowadays, many people are looking for a milder substitute for C (antioxidant) in morning C and evening A. Olive leaf extract here is not a good substitute, but it is a good hand when used for after-sun repair.

3. Repair:

This is actually the unknown killer of olive leaf extract, which can not only resist oxidation, but also promote PPAR up-regulation.

PPAR is a signal molecule, which is related to the synthesis of lipids and even collagen, thus increasing collagen IV (the main component of basement membrane) and repairing the inner wall of skin (basement membrane).

Of course, the repair of sensitive muscles should not only take care of the inner wall (basement membrane), but also the outer wall (stratum corneum), such as using products containing ceramide and squalane.

02

How to choose products?

There are many products containing olive leaf extract in the market. How to choose? Let’s talk about it one by one:

Although everyone adds olive leaf extract, their family has its own patent, which is mainly aimed at a series of optimization of the active substance of oleuropein mentioned above. After optimization, the oleuropein component in the raw materials can be stabilized at around 6-10%.

The dosage of the formula reached 10%, much higher than the 1% suggested by the raw material supplier, which may be the reason why it works so well. In addition, the formula also added zinc gluconate for oil control and a small amount of arbutin for whitening.

On the whole, this product is a good choice except that it is expensive and suitable for relieving acne muscles or for fear of causing post-inflammatory pigmentation after using heavy drugs.

 

CSS, an olive gel, is known as a flat version of Ou Ma. Although the core ingredient is not Omaqiang, the olive leaf extract is directly dried to 19%.

At the same time, Centella asiatica and various peptides are added, which will be more suitable for the soothing use of anti-aging people in general. For example, it is a good choice to form cp with alcohol A.

 

Yan Yan’s anti-oxygen mada combines soothing and anti-oxidation.

3% ethyl VC+ powder ergothionine (antioxidant devil) forms a circulating antioxidant effect in the epidermis, and you don’t have to worry about skin oxidation and dullness all day;

The callus extract and mosaic extract of Leontopodium alpinum are also added, which are rich in edelic acid and increase the anti-aging function in the direction of strengthening anti-oxidation; Under the action of olive leaf extract, this multi-channel antioxidant combination has become extremely gentle, and it has become a star anti-oxidation and brightening item that sensitive muscles can also use happily.

 

Mainly 3% tranexamic acid +2% olive leaf extract +1% rhamnose, on the whole, it will be more suitable for dealing with red acne marks, because tranexamic acid itself has a good repair effect, and it is a whitening raw material that Japan likes to use.

This small green bottle of Baizhu Extract is known as colorless and plain, which tastes like a cocktail formula. Anyway, this bottle has all the common soothing ingredients, including chamomile extract, β-glucan, olive leaf extract, etc., and it also adds PCA zinc, which is more suitable for soothing oil skin.

Ok, that’s all for today. What else do you want to dig into? Please leave a message in the comments section ~

Weng Weijian, a TCM health expert: Health should be kept sooner rather than later.

Mr. Weng Weijian is a professor at Beijing University of Chinese Medicine and a famous health care expert. Anyone who meets Professor Weng himself is moved by his special temperament. At the age of 83, his body is tough and his skin is delicate, which is completely unlike an old man. Mr. Weng founded the first Chinese medicine nutrition specialty in China before his death, and made outstanding contributions in many fields such as Chinese medicine teaching, scientific research, diet therapy, health preservation and rehabilitation. The theory and method of health preservation advocated and practiced by him are precious wealth for future generations.

Professor Weng said that the purpose of TCM nutrition and health care is not just to treat diseases and prevent diseases. From a deeper level, it is to use natural diet to keep the human body in the best or even extraordinary state. He believes that the two characteristics of food performance, tonic and diarrhea, can best reflect the theme of TCM nutrition. He said that food supplements replenish qi, nourish blood and replenish essence; Diarrhea can relieve exterior syndrome, fire and poison. He developed thousands of recipes for China health food (longevity diet) and medical health food (medicated diet). Mr. Weng’s medicated diet is not a food containing drugs, but a natural food containing drugs, which is harmless to human body. Medicine and food should be eaten together. In his view, only color, taste, fragrance and shape are not comprehensive, and "quality" should be added. This quality is rich in nutrition and has a health care effect.

Professor Weng Weijian has been engaged in health care for 20 years, and summed up a set of health care experience from "eating, pulling, sleeping, urinating and walking": "If you want to live longer, your stomach will be clear; Don’t be partial to food, don’t blame food, and eat omnivores. " To eat miscellaneous food, eat at least 30 kinds of various foods every day, and eat breakfast seriously; Have enough stool every day, preferably twice. For this reason, eat more fiber-rich food and drink more boiled water, and drink at least 8 cups of boiled water in ordinary water cups every day. Old people go to bed early and get up early, and their sleep time is sporadic. They should let nature take its course, and they can sleep at any time when they are sleepy. Bite your teeth tightly at the moment of urination and don’t make any noise, which can make your teeth strong. As long as you persist for a long time, the troubles such as poor urination will be alleviated or even disappeared; People are old before their feet, and there are more than 20 acupuncture points on the soles of their feet. It is a good way to keep stimulating and walk for one hour every day. No matter what the season is, we should insist on scalding our feet with hot water for 15 minutes before going to bed. One or two Chinese medicinal rhubarb can be broken, wrapped in gauze, boiled for 15 minutes, and then washed with this water, which has the functions of diminishing inflammation, sterilizing, promoting blood circulation and removing blood stasis.

He also said: it is better to keep in good health sooner than later. Health preservation is not a science of providing for the aged. People’s aging has already begun before the arrival of old age, and health and longevity activities should be carried out in many aspects of life as soon as possible.

People’s leaders | be young friends

On the eve of the May 4th Youth Day in 2022, the Supreme Leader visited China Renmin University.

There are two old photos in the quiet exhibition hall of the history exhibition of the National People’s Congress: one is a photo of the supreme leader and college students; The other photo was taken in Zhengding county government guest house, where the supreme leader and college students sat on the bed and had a long talk.

On July 29th, 1984, the Supreme Leader had a discussion with members of the Summer Social Practice Group of China Renmin University in Zhengding County Government Hostel.

The photo records a past event that happened in the summer of 1984 — — The summer social practice mission of China Renmin University went to Zhengding, Hebei Province for investigation, and the supreme leader of Zhengding County Party Committee made a special trip to visit college students by bike.In Zhengding county government guest house dormitory, the supreme leaderTalk with you and share your experience in grass-roots work for two hours.

From the local to the central government, youth has always been the concern of the supreme leader.

Go deep into the youth, "become one with the vast number of young people" and "be a youth friend, not a youth ‘ Officer ’ " "Be the bosom friend of young friends" … … This is what the supreme leader often says and what he does.

Supreme leaders often go among young people and communicate with them on an equal and cordial basis.

On January 17, 2019, the Supreme Leader had a cordial exchange with teachers and students at the State Key Laboratory of Elemental Organic Chemistry of Nankai University in Tianjin.

On January 17, 2019, the Supreme Leader had a cordial exchange with teachers and students at the State Key Laboratory of Elemental Organic Chemistry of Nankai University in Tianjin.

In 2009, he came to Tianjin University to visit the students who stayed in school during the holiday, and said humorously, "I would like to talk with our classmates ‘ Talk big ’ " ; At a symposium in 2015, he used his personal experience as an example to persuade young people not to stay up all night. "There is passion inside, but we should take it easy outside"; In 2018, he shared his reading experience with his classmates in Peking University: "In the process of reading, through continuous re-examination, we can achieve the negation of negation, review the past and learn new things." "This conclusion drawn through our own thinking and understanding will be firm" … …

The supreme leader is also a pen pal of many young people. One reply after another, the paper is short and affectionate.

"Between the lines, I feel your determination and confidence to strive for the Chinese dream of realizing the great rejuvenation of the Chinese nation." All the students in the 2009 undergraduate league branch of Peking University Institute of Archaeology and Culture read the understanding and recognition from the reply from the supreme leader.

"The peasants have the truest feelings about your efforts and contributions. I have read a lot of materials reflecting the deeds of college student village officials and am happy for your progress and achievements." Zhang Guangxiu, a university student village official, felt affirmation and encouragement from the reply from the Supreme Leader.

"Strive to be a builder of the western region who can be useful and shoulder heavy responsibilities. I support this life choice you have made." The graduates of Karamay Campus of China Shiyou University (Beijing) received recognition and support from the top leader’s reply.

… … … …

"There is no shelf of great leaders at all, and there is no mandarin or cliché. Instead, they communicate with us like big friends." "It gives people the feeling that they are so easy-going and kind" and "very approachable" … … This is the impression left by the supreme leader on many young people.

On May 28th, 2023, the resident college students of Xifangezhuang Village Science and Technology Academy in Yukou Town, Pinggu District, Beijing measured the hardness of tomato fruit in Jingwa Greenhouse Horticultural Demonstration Park in Yukou Town, Pinggu District.

On May 28th, 2023, the resident college students of Xifangezhuang Village, Yukou Town, Pinggu District, Beijing measured the hardness of tomato fruit in Jingwa Greenhouse Horticultural Demonstration Park.

Youth is in the initial stage of life, and it is inevitable that they will be confused and confused during their growth. In the eyes of young people, the supreme leader is a "senior" and a "big friend". He always guides young people to take every step of life with words that they can understand and listen to.

He used the metaphor of "kneading dough" to explain the process of entering society to young people in a simple way: "When flour is kneaded with water and then kneaded, it is easy to disperse. But if you keep rubbing it for thousands of times, it will never spread out again. " The supreme leader used this vivid metaphor to tell young people that only when a person grows up under various tests can he really withstand the pressure of life.

Talking about learning, the Supreme Leader encourages young people to "draw knowledge like a sponge" and practice excellent skills; Speaking of physical fitness, he introduced his sports hobbies and encouraged young people to do well in their studies and make their bodies great; On self-cultivation, he exhorted young people to "button up their lives from the beginning" and cultivate a correct value orientation … … Good words are the mutual understanding between friends, and also the advice and encouragement from the predecessors to the younger generation.

In the Hengqin Campus of the University of Macau, I saw that all the students were full of youthful vigor. The supreme leader quoted two lyrics to talk about patriotic complex: one was "Build our new Great Wall with our flesh and blood" in the national anthem, and the other was "But they took my body away, and you still keep my inner soul" in the Song of Seven Children.

"I can always hear new ideas and be touched." The supreme leader’s personal feelings infected every young person present.

Youth dreams, home and country. Under the care of the supreme leader, every seed of youth has accumulated the power of growth.

"The young people in China in the new era are good and worthy of great responsibility!" "Where is the future? The future is here for you. " The supreme leader’s entrustment to young friends is also the expectation for the future of the motherland: "This loong must have a backbone and hold on, so that she can take off higher."

Interview with Bai Yongrui: My life and ideological experience

[Editor’s Note] This interview was conducted in Seoul on August 24th, 2015. The interviewer was Professor Takahiro Nakajima of the Center for Philosophy Research of the University of Tokyo, Japan, and the interviewee was Professor Bai Yongrui of Yonsei University, South Korea, with Jin Hang as the translator. The original title of this article is "Giving Vitality to the Gap: An Interview with Bai Yongrui", which was signed by the author as "Conversation between Nakajima Takabo and Lu Chan" and published in Thought magazine (published by Lianjing Publishing Company on December 14, 2017). Reprinted by The Paper with authorization. The original interview was 20,000 words long, and here are some excerpts. There are notes in the original text, which are omitted here.

I. Born in Incheon shortly after the signing of the Korean Armistice Agreement.

Nakajima Takahiro:When planning this dialogue, two texts came to my mind. One is a dialogue between Emmanuel Lévinas and Philip Nemo. This was originally an interview in a radio program, and later it was compiled into a book called Ethics and Infinity. This book is very good. Levinas talks about his philosophy in it, and there are some things that he may not put into writing. On the question "What kind of philosophy is Levinas’ philosophy?", he expounded it in his own words, which is very simple and easy to understand. I want to use this as a model to talk to you today. The dialogue between Levinas and Nemo began with the former’s childhood memories, and another text that came to my mind happened to be walter benjamin’s Childhood in Berlin around 1900. Today, I want to start a dialogue with these two texts as examples. First of all, please ask Professor Bai to recall his childhood and let everyone know the story of Bai Yongrui (= history).

Benjamin said in the book: "The picture of my urban childhood may be able to shape the future historical experience in advance." He listed his unique historical view and some corresponding childhood impressions. Excuse me, what is Professor Bai’s impression of his childhood?

Bai Yongrui:First of all, I would like to thank Professor Nakajima for coming to Seoul. Among the questions received in advance, it was written that "personal issues do not involve privacy issues". I think you indicated this article with reference to Benjamin and Levinas. This inspired me and looked back on my childhood.

First of all, I want to emphasize one point. I was born in August 1953, shortly after the signing of the Korean Armistice Agreement (July 1953). My parents were born in Huanghai Road, North Korea, and moved to the south across the 38th parallel, which is called "Vietnam" in Korean, so my parents are both "Vietnamese citizens". This kind of birth and experience formed my first impression of childhood.

Incheon, like Yokohama in Japan, is also a seaport city that opened to the outside world very early. I was born in the slums of this city. Although he was born in a slum, he was not a poor family. My father is a primary school teacher, so our family is a rich class in the slums. I have been very sensitive to the "difference" between the poverty around me and my living conditions since I was a child. I am not only insensitive to the gap between the rich and the poor around me and the differences between myself, but also worried about poverty and the gap between the rich and the poor although I was a child.

My sensitivity to the gap between the rich and the poor probably stems from two influences. One is Christianity. My mother is a Christian. Under her influence, I learned to understand and face the gap between the rich and the poor. The other is family reasons, and parents are not in harmony. As a "Vietnamese citizen", there are often disputes at home. Mothers are sometimes treated violently by their fathers, which is a domestic violence. I have been thinking about "why do we live in such a violent environment" since a long time ago, and I feel the same for my mother. Because of this experience, I have a certain feminine sensibility inside. In short, one is the influence of Christianity; The second is thinking about the abused vulnerable groups such as women, that is, the minority groups in society. Since then, I have developed a perceptual knowledge of the weak and the poor in my body.

When I was young, I spent more time reading and writing at home than playing with my friends next door. Later, these became my interests and I spent most of my time on books. Maybe I have a little talent. My composition often wins prizes after school. In junior high school and senior high school, I participated in literary and art activity groups. When I was in college, I wanted to study literature, especially Chinese literature. However, they are opposed by their parents. They think that "learning literature and being poor all their lives" should be studied in law or philosophy. Finally, I made a compromise and chose history.

Tsukagoshi Hirotaka Nakajima:Recently, I just read Xian Xixian’s Till Death, and found that Christianity had an extremely important influence in South Korea in the second half of the 20th century. As a Christian, your mother should often be exposed to poverty.

Bai Yongrui:Christianity has played many roles in Korea. Especially in improving the status of women, this has become a religious and social phenomenon. After being hurt by her father, my mother may have found solace in the church. Until now, the church still has the function of spiritual healing. From the perspective of Christianity improving women’s status, my mother has no formal education, but learned Korean and parenting knowledge in church, and was exposed to society and culture.

My mother was deeply influenced by the church, and I was deeply influenced by my mother. However, in the process of my growth, this influence has become a huge burden in terms of emotion and sensibility. Give an impressive example. In my junior year, I was arrested and imprisoned for participating in the student movement. It was a winter, and when I thought that my son was in prison for the winter, my mother didn’t use the heating all winter. This is "maternal love and burden go hand in hand". In addition, through the communication with the parents of those students’ sports companions, the mother also joined the democratization movement. Under the influence of Christian spirit, the mother gradually regarded the love for her son and the democratization movement as one. I witnessed the changes in my mother with my own eyes and was surprised that a person could change like this. This is a very deep impression on my mother.

Tsukagoshi Hirotaka Nakajima:I once asked the Koreans in Japan and South Korea. It is said that the problem of domestic violence among Koreans in Japan and South Korea was once very serious. Later some young people criticized this. Those who were familiar with the situation at that time could not give a reasonable explanation even if they were condemned. Of course, the same problem exists in Japanese society, and many families have experienced violence. From this, I thought that those war wounds that are everywhere may be vented in the form of "domestic violence". This is not only a matter of Professor Bai’s family, but also a common problem in East Asia.

If you are not afraid of misunderstanding, isn’t it because of the influence of childhood environment that Professor Bai has paid attention to minority groups? However, unlike you, more people choose to solve the problem through male or paternalistic violence.

I think that "minorities" are often associated with some kind of "fairness = fairness". Professor Bai once wrote that the antonym of forgetting is not memory but justice. That’s true. But besides "justice", I deeply feel that there is fairness in it. After listening to Professor Bai’s words just now, I think it is precisely because of your childhood impression of your mother.

Bai Yongrui:As Professor Nakajima said, the transformation of war trauma into domestic violence is not only a problem for our family, but also a common phenomenon throughout East Asia. We abandoned our wealth and took refuge from the Yellow Sea Road in North Korea. As "Vietnamese citizens", our lives were hard. Trauma is manifested as the violence of interpersonal relationship.

I witnessed my mother’s misfortune, and thus I became concerned about the minority. This is concern for the mother or the weak. But at the same time, there is also an important reason for his father’s misfortune, or that his life should be like this. The concern for minorities or feminism is not limited to the concern for the weak, but also the concern for interpersonal relationships and people themselves. In violent relationships, people themselves are devastated. I have a deep understanding of this since I was a child.

Looking back on the past, men in adolescence will have the illusion and desire to show their masculinity. But I am small, even if I want to be such a man, it is unrealistic. Because of this, I began to think about my body. This may be an opportunity for me to understand women later. Recently, I began to use the expression "female element in myself". Childhood memories leave not only rational perception, but also physical memory.

Tsukagoshi Hirotaka Nakajima:In Professor Bai’s thesis, there have been many expressions about body feeling. But this kind of physical feeling keeps a certain distance from the thought, which is impressive. Although the dialogue will be mentioned again later, now I want to say that the part based on physical feeling is an important element in the "universality" that Professor Bai thinks about. It seems that there has always been a strong physical feeling in your article.

Bai Yongrui:Thank you, Professor Nakajima, for reading my article. But as far as I’m concerned, I didn’t realize that I would resort to words for my physical feelings. It should be said that this is my future topic.

Professor Bai Yongrui

Second, the crisis of reading life and peace

Tsukagoshi Hirotaka Nakajima:Next, let’s change the topic. Please ask Professor Bai to talk about his childhood study life. Levinas mentioned in his dialogue with Nemo that he read Russian literature when he was a child. Levinas said that although he did not need to regard himself as a Russian national, he still read Russian literature. What books did you read when you were a child?

Bai Yongrui:When I was in primary school, I read the world famous books published for boys and girls. After entering middle school, I read the complete works of world literature. But I didn’t limit myself to reading a certain country’s literary works like Levinas did.

Tsukagoshi Hirotaka Nakajima:Are there any works that are particularly impressive?

Bai Yongrui:What impressed me most was a reading experience in Grade Two or Grade Three. Living in a slum, only the priest can study together. We read History and Eschatology by Rudolf Karl Bultmann. This is a book about theology. After reading it, I became interested in such questions as "What is the power to push history forward", "Some law to control history" and "What is faith". Just now, I said that my choice of history was the result of compromise with my parents. To tell the truth, I didn’t really accept it myself, but in retrospect, maybe it has something to do with that reading experience.

At that time, the history department of Seoul National University was divided into Korean history, oriental history and western history. I chose Oriental History without hesitation. One of the reasons is that I am very interested in how Bultmann’s historical philosophy, historical laws and historical forces reflect these problems in East Asia.

Another reason is the situation at that time. In 1971, Sino-US relations began to ease. The relaxation policy is spreading, and people’s attention to China is increasing. Influenced by this, I chose Oriental History.

Tsukagoshi Hirotaka Nakajima:I think many people have had this experience, and in the process of growing up, there was some kind of identity crisis. Some people have survived this crisis, while others have not. What kind of junior and senior high school life did Professor Bai experience before he went to college? Is it calm or full of crisis?

Bai Yongrui:I have hardly experienced an identity crisis (laughs). My junior high school and senior high school are famous local schools, and I have been the president of the student union, and the activities of the literary and art activity group are also very smooth. It can be said that as a good student, I live a model life.

However, I experienced a big crisis in my freshman year. At that time, the principal graduated from Hiroshima Normal School and was an anarchist comparable to Xian Xixian. He insisted on his own idea and changed all school exams to unsupervised. An English quiz in Grade One of Senior High School was not as formal as the mid-term or final exam. I cheated. After being discovered by the English teacher, I was not only punished by corporal punishment, but also taken to the office for one day. For me as a model student, this incident has become a huge trauma.

For a period of time after that, I didn’t want to go to school, and I was not interested in anything. I began to learn and try to master French, which became an opportunity to make up for the trauma. Although it was a kind of self-satisfaction, it did help me through the difficulties.

Tsukagoshi Hirotaka Nakajima:Why study French?

Bai Yongrui:After the recovery of Korea, German was the second foreign language. In my freshman year, I could choose French besides German. I am not interested in law, but I am interested in literature, history, philosophy and French literature, so I naturally choose French. Maybe the aversion to law is too strong.

The experience of cheating in the exam in senior one and the experience of being imprisoned for participating in the student movement just now made me understand how fragile and precarious the "peace" created around me is under external forces.

Tsukagoshi Hirotaka Nakajima:Benjamin’s Childhood in Berlin around 1900 also gives people a premonition that the unique calm state of childhood will be broken. Perhaps everyone will find out after adulthood that if it is not created by themselves, in the words of Professor Bai, it is the "peace" generated by their own judgment, then it will not be realized. Professor Bai experienced this in high school, didn’t he?

Bai Yongrui:I thought I created peace through my own feelings, but in fact, it was not through my own internal judgment, but based on the surrounding environment or the judgment of adults and schools. They think you are excellent, so I cooperate with external judgment to create a kind of peace. This is not the peace created by your own judgment. That "crisis" also gave me a chance to reflect on how fragile the so-called "model" is.

Tsukagoshi Hirotaka Nakajima:Have you participated in student sports since high school?

Bai Yongrui:In high school, I was not interested in student sports. I mentioned Bultmann just now. Actually, I was interested in historical philosophy at that time. However, after entering the university classroom, I found that there is no philosophy of history, but all courses are positivism. This may be influenced by Imperial University of Japan, and teachers have been discussing how to demonstrate historical facts. As a result, I gradually lost my interest in learning and couldn’t read well. Fortunately, students take part in the study meeting on their own-called "society" in Korea, which is similar to an ideological interest group-where they can learn about historical philosophy. In other words, we can discuss such issues as "What are the laws of history and the forces that push history forward", "What is the structure of capitalism" and "Who is the subject of history", and share various experiences with contemporary students.

Benjamin’s Humpty Dumpty: Childhood in Berlin Around 1900

Third, student sports and "learning as sports"

Bai Yongrui:After I went to college, I became interested in the structural problems of Korean society and joined a group aimed at cultivating social activists. Although the ideological interest group I joined had some connection with the student movement, what was more urgent at that time was the "October Reform" incident in Korea in October 1972. That is, President park chung-hee will change the constitution to realize the lifelong presidential system. Revise the constitution, formulate the "Reform Constitution" and move towards dictatorship. This happened in my freshman year. I went to school that morning, and the chariot was parked in front of the gate. The soldiers took control of the gate and drove the students out of the campus. Then, the university entered a state of long-term suspension. People can’t vote for the president directly, which runs counter to the democracy I learned in middle school and university. I can’t forgive the government’s behavior. This has also become an opportunity for me to directly participate in the student movement. The discussion about history study mentioned just now, for me, the influence from the ideological interest group far exceeds the formal university classroom, and its influence has continued to this day. As my own view of learning, I practice "learning as a sport". This is also directly related to the current research.

Tsukagoshi Hirotaka Nakajima:I want to confirm the date. President park chung-hee promulgated the National Education Charter in 1968. At that time, Professor Bai was still a high school student, right?

Bai Yongrui:Grade three.

Tsukagoshi Hirotaka Nakajima:Professor Bai just mentioned that when you go to school, you can choose French as a second foreign language besides German. Is this a system reform because of the promulgation of the National Education Charter?

Bai Yongrui:There may be other reasons for adding two foreign languages. The important educational reform in 1968 was the beginning of military training in schools.

Tsukagoshi Hirotaka Nakajima:Dictatorships and similar regimes are bound to intervene in education and try to change it. The park chung-hee regime has completely intervened and changed this. You entered the university in March 1972, and the university was blocked six months later. How long did this blockade last?

Bai Yongrui:Five months.

Tsukagoshi Hirotaka Nakajima:What happened in the meantime?

Bai Yongrui:Let’s talk about how the Reform Constitution elected the president. First of all, the "National Assembly of the Unified Subject" was established as the appointed body of sovereignty, and the president was indirectly elected through this meeting. Shortly after the October Reform, a meeting was held to elect a president. After that, various systems were improved by issuing presidential decrees. These things happened during the five months when the university was blocked. The regime established in the "Reform coup" became an orthodox regime, during which universities were closed. An exam was held in February, and the term ended.

Tsukagoshi Hirotaka Nakajima: You just said that when Nixon visited China in 1972, China and the United States started dialogue, and the situation in East Asia, including Japan, changed dramatically. As a history student, you should have thought a lot at that time, right?

Bai Yongrui:Let me explain the characteristics of the student movement at that time. The student movement at that time was not so much a political movement to change the system or play a certain political role as a large-scale cultural movement. Recently, some American scholars suggested that the student movement in South Korea in 1970s and 1980s created a "Counter Public Sphere". Let’s not talk about whether we should use this term, but our goal at that time was to build a popular national culture as an alternative to the orthodox culture of nationalism. Participating in the construction of alternative culture is the common value of activists. The main reason why the student movement can last until the 1980s is not only that it is a political movement, but also that it wants to create alternative culture in all fields of social life, and this conceit is the spirit of the student movement.

Tsukagoshi Hirotaka Nakajima:Since the beginning of the increasingly powerful reform system, you have spent this time as a college student.

Bai Yongrui:In April 1974, a large-scale demonstration took place in South Korea. This is a national parade led by college students. The authorities announced that the "All-China Federation of Democratic Young Students" led the March and attempted to create civil strife. They arrested the student leaders, and I was one of them. The All-China Federation of Democratic Young Students is referred to as the "Youth League". In fact, the Youth League of China is not a systematic organization. However, the authorities believe that this is an organization instructed by North Korea to act in a unified manner in an attempt to launch civil strife. I don’t have any officially appointed position, just a parade liaison in Seoul National University.

In the end, I was arrested as one of the masterminds of the civil strife. That parade happened just during the emergency measures taken according to the Reform Constitution, and the whole trial turned into a military trial. I was sentenced to seven years in prison and expelled from the university. At that time, the newspaper reported the Youth League as a criminal organization and attached a grass-roots organization chart. I’m in there, too. They said that behind this "criminal organization" was an organization called the People’s Revolutionary Party, in which spies instructed by North Korea attempted to launch a revolution, including Japanese independent journalists. In fact, the "People’s Revolutionary Party Incident" is part of a large-scale civil strife conspiracy fabricated incident. Later, when Roh Moo-hyun was in power, the case was retried. The court ruled that this was a fabricated event without any factual basis. In 2013, I was acquitted in the final trial, and seven years’ imprisonment was invalid. I was officially rehabilitated.

Tsukagoshi Hirotaka Nakajima:It took nearly forty years.

Bai Yongrui:If you look at my resume, you will find that I seem to have studied in college for nearly nine years. In fact, from 1974 to the end of 1979, I was counted as a "student without citizenship". After the death of President park chung-hee, I was able to resume my studies in March 1980 and then graduated.

Tsukagoshi Hirotaka Nakajima:Before, I went to Jeju with Professor Bai. The "Jeju Island April 3rd Incident" in 1948 was also considered to have North Korea behind the scenes, and many people were killed. Such fabrications keep happening. Just now, you said that there were Japanese independent journalists in the People’s Revolutionary Party incident. What was the connection between the student movements in Korea and Japan at that time?

Bai Yongrui:I don’t think there is a direct connection between the two. Although Japanese and Koreans can bring Japanese books when they study in Korea, it is by no means easy and can easily be regarded as spies. Due to the situation at that time, everyone could not keep in touch with the outside world. After reading the works of the famous brothers Xu Sheng and Xu Jingzhi, you will know that it was a difficult time.

Tsukagoshi Hirotaka Nakajima:The reason why I asked the question just now is because the student movement in Japan was at the end in 1983 when I entered the university, and everyone received a lot of news about the Korean student movement. Therefore, in my impression, students who participated in the Japanese student movement also participated in the Korean student movement, and there is a connection between the student movements in Japan and South Korea. But you just said that it would be regarded as a spy, which seems very difficult!

Fourth, reading life in prison

Tsukagoshi Hirotaka Nakajima:What books did you read in prison? What thoughts have you made?

Bai Yongrui:Although he was sentenced to seven years, the actual detention period was ten months and fifteen days. When I was in prison, my mother took part in the democratization movement. At that time, the democratization movement of the whole society was in full swing. The authorities were forced to make concessions and suspended my sentence. He was released from prison in February 1975. Although I stopped serving my sentence, I was not acquitted, so I could not return to school. Just like parole, you can’t go back to college, and you can’t walk around at will.

There are two books that are very important to my prison life. One is Taijun Takeda’s Sima Qian. After reading this book, I was deeply moved by Sima Qian’s spirit of writing history in a difficult situation. When I read that he was still recording history in prison after being tortured, I couldn’t help crying.

Another book is Li Yongxi’s The Theory of Changing Times, which is the fourth in a series of new books published by the Creation and Criticism Society. This book was lent to me by my cellmate Lee Hae Chan, who later became the prime minister of Roh Moo-hyun’s government. When he lent me a book, he said that after reading this book, you will have a new understanding of the China Revolution and the Vietnam War. Therefore, I take it for granted that this is a Japanese book, and I never thought that there would be such works in Korean books. I secretly got it in prison and found that it was actually a Korean book. There are new ideas about the "Cultural Revolution" in the book, and there are many new understandings of the history of China, including the "Cultural Revolution", which deeply shocked me after reading it. This book has refreshed my understanding of the history of China. It was not the class at Seoul National University that prompted me to revisit the study of China’s history, but the book The Theory of Changing Times that I read in prison.

Except me, all young Koreans in the 1970s were deeply influenced by this book. Including the late President Roh Moo-hyun, this book had an absolute influence on the young people at that time, so Li Yongxi was called "the mentor of the times". From the present point of view, you will feel that he is over-beautifying the "Cultural Revolution" and the Vietnam War. But at that time, during the period of capitalist development after rapid economic growth, various problems emerged in Korean society. This book provided us with a mirror to reflect on reality and understand ourselves. This is the meaning of this book. In short, The Theory of Changing Times is like putting a mirror outside us, so that everyone can reflect on themselves. In this sense, this book, as a weapon to criticize Korean society, has achieved remarkable results. Even now, we should acknowledge its value.

Li Yongxi later wrote Idol and Reason. This title simply and clearly summarizes the mental state of Korean society at that time. ……

In the situation in East Asia at that time, the atmosphere of reconciliation and relaxation policies between China and the United States swept across the country. In such an international situation, the key word "transformation" was generally accepted by Korean society at that time. If we regard this era as an era of transformation, we need new theories that conform to this era. Idol and Reason is a work that meets this requirement. Therefore, Li Yongxi’s works were accepted by many young people at that time.

Tsukagoshi Hirotaka Nakajima:This is "learning as a sport".

Bai Yongrui’s Thoughts of East Asia

V. Changing society through language

Bai Yongrui:After I got out of prison, I was in a state of nothing to do. Criminal police often followed, and the general environment at that time was that the participants in the student movement either engaged in political activities in the wild, or worked in factories under cover, and then formed trade unions to carry out labor movements. These are the ways for people who are interested in the revolutionary movement, but I can’t do it. Later, I became an editor in a publishing house. This publishing house is the "Creation and Criticism Society" that is still related to me (its name was changed to "Chuangpi" in 2003).

Shortly after I got out of prison, I visited teacher Li Yongxi’s home. I admire Teacher Li very much. We read and discussed together, from literature to the revolutionary history of China. At the same time, as an editor, I work with books. Because of some trauma in my mind, or some feeling I have had since childhood, and I like reading and writing, I began to realize that it is my duty to change society through language through editing this job.

Of course, the reason why I think of changing society through language is also related to my personal habits and growing experience. But the most important thing is that I do feel the reform power of language. What impressed me the most was after returning to the university campus in the spring of 1980. At that time, the university wall was covered with posters, on which students quoted Mr. Li Yongxi’s words and extracted sentences from books and magazines published by my creative and critical society, showing the demand for social change. Seeing this, I deeply feel the power of language and how important it is to elaborate ideas.

Tsukagoshi Hirotaka Nakajima:You can feel the vitality of language by quoting the ideas in the books of Teacher Li Yongxi and the Creation and Criticism Society. When I was in college, there were also vertical billboards and posters on campus, but the words on them made people feel old and lifeless. I passed the end of the student movement in Japan, which was completely different from Professor Bai’s experience.

After resuming your studies, you graduated from undergraduate course in August 1981. In March of the following year, I entered the Graduate School of Tankook University (Korean schools graduated in August and entered in March). At that time, many partners who participated in the student movement and colleagues in the creative and critical society were outside the university campus. Who did you mainly act with?

Bai Yongrui:First of all, Lee Hae Chan mentioned just now, and Jin Zhihe, a poet who served his sentence together. Immediately after I got out of prison, I went to see Mr. Li Yongxi and studied the revolutionary history of China with him. Jin Zhihe told me that you shouldn’t be a political athlete or a labor athlete, you should be a scholar. He also said that Teacher Li Yongxi viewed the China issue from a journalist’s point of view. As a scholar, you can study the history of China as an ideological issue or a historical issue, which is exactly what you need now, and this is also your duty.

Six, from the history centered on human history to social humanities.

Tsukagoshi Hirotaka Nakajima:Just talking about Taijun Takeda’s Sima Qian, China’s historiography pays attention to exploring the changes of the times and its reasons, which is different from the emphasis of modern historiography. The history you want to learn from Mr. Li Yongxi is about the historical structure of the China Revolution, but it seems to be a combination of traditional China historiography and modern historiography to discuss how this structure came into being and how it changed.

Bai Yongrui:Professor Nakajima’s comments are very interesting. So far, I haven’t thought deeply about this problem. Now I can explain my thoughts.

Modern historiography expounds history with the system and structure as the center, but China’s viewpoints and narratives focus on people. I think we should find a narrative way that can transcend these two historiography. Therefore, we should focus on "people" first. However, this does not refer to a famous person or related historical stories of China, let alone modern historiography which focuses on system and structure. What I am concerned about is not the "people" themselves, but the relationship between those who live in the system and the structure. This is "history centered on human history". I wonder if I answered your question just now. How to develop history centered on human history is my current research topic.

Tsukagoshi Hirotaka Nakajima:There are also historians like Naito Hunan. Naito’s stories are large in scale, which makes people understand the reasons for the rise and fall of traditional China’s rebellion, but in the end, it encourages the contempt for China at that time. Naito tried to combine the discussion of system and structure in modern historiography with China’s traditional historical narrative in some way, but eventually he lost his critical consciousness of the Japanese status quo.

Compared with Naito’s practice, Professor Bai wants to develop the two methods as two intersecting lines, which is exactly the opposite. In other words, your approach is neither to focus on the characters in China’s rebellion, nor to focus on the system and structure but make the characters disappear from history, as in modern western historiography. Therefore, Professor Bai’s article not only pays attention to human history, making it appear repeatedly, but also has a critical consciousness of the present situation.

Bai Yongrui:I am very grateful to Professor Nakajima for evaluating my research work from that perspective. You said that my research method is completely opposite to that of Naito Hunan, and I was really scared. In any case, Professor Nakajima did point out the direction of future historical research with a novel point of view.

No matter what changes and twists and turns occur in history, history must focus on human history. For me, this is the most important thing. The reason why I regard human history as the main content of historical research is not only because I have paid attention to literature since I was a child, but also because of my later creative activities in the quarterly journal of literary politics, Creation and Criticism, and the Creation and Criticism Society. Creation and Criticism is a comprehensive magazine that involves and intervenes in social movements and the current situation. It has exercised my sensitivity as an editor and a reporter. Later, how to construct and expound the history centered on human history became my main research topic. From this point of view, the crisis of "history as a system" and "history as an academic" is precisely a result of these historical studies ignoring human history. Therefore, in order to get rid of the "institutional" history that caused this crisis and result, I have always emphasized "history as empathy".

Tsukagoshi Hirotaka Nakajima:I’d like to ask Professor Bai again about the relationship between "academic" history. Excuse me, what was written in the graduation thesis of this master’s period?

Bai Yongrui:The undergraduate thesis is about Liang Shuming’s rural construction movement. My master’s thesis originally wanted to write about the May 4th Movement or the Communist Movement, but Mr. Min Douji suggested that, based on your experience, if you do research on the Communist Movement or Radicalism, it is not conducive to finding a job in the university in the future. On the contrary, you should study the Kuomintang movement, which is considered a "reactionary" even in China. Therefore, the master’s thesis wrote Zhu Zhixin, the left wing of the Kuomintang.

Tsukagoshi Hirotaka Nakajima:I see. My master’s thesis was written by Zhu Zhixin, and later I did research on Dai Jitao who put forward the theory of national revolution.

Bai Yongrui:Zhu Zhixin was also one of the propagandists of Marxism, so he was studied in his master’s thesis. As for Dai Jitao, Japanese Sun Wen Studies introduced my Dai Jitao studies.

Photo taken on Dai Jitao’s rickshaw (taken in Tokyo in 1916). At the top left of the photo, it says "When I went to greet before the 5 th anniversary of the Republic of China". Hidden in the Meiwu Zhuangji Reference Room.

Tsukagoshi Hirotaka Nakajima:Have you been studying with Mr. Min Douji since you were an undergraduate at Seoul National University?

Bai Yongrui:Teacher Min Douji’s influence on me only became greater after the 1980s.

Tsukagoshi Hirotaka Nakajima:I see. I thought you and Mr. Min Douji knew each other for a long time.

Bai Yongrui:After I got out of prison, I went back to the university campus first. After entering the graduate school, I entered the door of teacher Min Douji.

Tsukagoshi Hirotaka Nakajima:When you first entered Seoul National University, wasn’t Mr. Min Douji there?

Bai Yongrui:When I entered school, Mr. Min Douji was already a teacher at Seoul National University, but he went to Germany for academic leave. Moreover, I have only taken one class, and there is no intersection with Mr. Min.

Tsukagoshi Hirotaka Nakajima:Just now you mentioned that positivism prevailed in the history department, and Mr. Min Douji was not one of them.

Bai Yongrui:In fact, there was another thing that happened. When I submitted my application for admission to the Graduate School of Seoul National University, I was told that I was not qualified for admission. At that time, Mr. Min Douji was very angry with the university’s decision and said that "it is impossible to be unqualified, what is going on". He told me that even if I failed, I could go to the exam first. In the end, I didn’t get into the graduate school of Seoul National University.

Tsukagoshi Hirotaka Nakajima:Therefore, you went to the Graduate School of Tankuo University.

Bai Yongrui:Although I entered the master’s program in the Graduate School of Tankuo University, I received personal guidance from teacher Min Douji for three semesters. This is not a formal research class, but one-on-one personal guidance, including the history of China’s philosophy, the history of Chinese historiography and thesis guidance. After entering the late period of Quan Douhuan’s regime, the social restrictions on former student movement participants were reduced. Unlike when I took the master’s degree, I was able to enroll in the doctoral program of the graduate school of Seoul National University. So, I returned to Seoul National University.

Tsukagoshi Hirotaka Nakajima:So, once again, you are under the door of Mr. Min Douji. What kind of person is Teacher Min Douji?

Bai Yongrui:I once compared the academic achievements of Mr. Min Douji and Mr. Li Yongxi in a critical study of China. For me personally, both of them exist in my heart like prosecutors. Teacher Li Yongxi may ask, can your article become a weapon of social change? Teacher Min Douji may ask, is your article writing based on strict academic norms? I often ask myself these two questions when writing articles.

In addition to South Korea, Mr. Min Douji is also a famous positivist in Japanese societies. But I have been in close contact with him and feel that he is not just a positivist. It is often said that Mr. Min Douji, as a liberal, did not take part in the action to change reality. Although Mr. Min Douji is not directly involved, he will severely criticize the real problems in his essays and other places. In fact, before I took part in the student movement, I had a meeting with Mr. Min Douji once during my undergraduate course. At that time, I wanted to study history and take part in political movements, and I didn’t know which way to choose. So I confessed my troubles to Mr. Min Douji. Now, I have also become a university professor. When students ask such questions, I always find it difficult to answer them. At that time, as a student, I asked this question to Mr. Min Douji. Teacher Min Douji suggested that I should strictly distinguish between "words and deeds as a citizen" and "words and deeds as a scholar", and recommended Max Weber’s "Learning as a Career". I opened the book with great expectation, expecting to read an exciting article, but Weber was throwing cold water on it and the content was serious. I gave up before I finished reading, and was later arrested and imprisoned for participating in the student movement. At that time, what bothered me was how to combine "learning as a system" with "learning as a movement", and how to distinguish and combine "words and deeds as a citizen" and "words and deeds as a scholar" that Teacher Min Douji said. Today, I am still looking for these answers.

Some people who know my relationship with Mr. Min Douji will wonder why people like Mr. Min Douji tolerate people like me who are keen on real politics and have been arrested and imprisoned for participating in the student movement. In this regard, I want to say at first that Mr. Min Douji is not only a positivist, but also a magnanimous person who can tolerate people like me. Dare not talk about the teacher’s private affairs, just say one thing. Teacher Min Douji was born in Jeolla-do, which was once a fierce guerrilla battlefield during the Korean War. Mr. Min Douji had a predecessor who died in guerrilla warfare. This predecessor was intelligent and eager to learn, and he was excellent. Before he took part in guerrilla warfare, he told Mr. Min Douji: I entered the war for the sake of righteousness. Although I can’t continue my studies, you must continue reading. The elder entrusted his full ambition to Mr. Min Douji, and Mr. Min Douji kept this agreement.

Tsukagoshi Hirotaka Nakajima:What a great teacher! At that time, you were studying under Mr. Min Douji, and at the same time, your intersection with the real society, especially with Creation and Criticism, was deepening. Through publishing work, contact with the society in different forms with student movements. Under Mr. Min Douji, your research has become more rigorous. These are things that Professor Bai grasped with both hands at that time. Excuse me, how do you promote knowledge research and social activities at the same time

Bai Yongrui:I’m still worrying about this problem. How to combine both at the same time? This is not only my personal problem, but also a problem related to my own research theme "academic history research" In other words, research is carried out around "learning as a movement" and "learning as a system", in which we objectively think about our identity. In this sense, the Japanese version of my book contains two articles that I like very much. One is The Birth and Decline of Oriental History, and the other is A Critical Study of China. I want to do some research on Korean studies and Japanese studies from this perspective as much as possible in the future.

Whether it is academic research or social activities, I am carrying on with these troubles. Before that, he served as the dean of the National Studies Institute of Yonsei University for seven years, and established HK(Humanities Korea, the national research project of Korea "Humanities Korea") with "Social Humanities" as the research theme. During these years, my colleagues and I have been thinking about how to combine "learning as a system" with "learning as a sport".

Whether we use the terms "learning as a sport", "learning as a system" and "social humanities" or not, we do meet companions who share the same values and think together everywhere. In the future, I want to move the main venue of the activity to the creation and criticism society outside the university, so that the social humanities can continue to carry forward.

Tsukagoshi Hirotaka Nakajima:From the beginning as an editor, Professor Bai has always had an intersection with the Creation and Criticism Society. Recently, you have become the main member, and your relationship with the agency has gone further. Excuse me, what is your relationship with Mr. Bai Leqing, editor-in-chief of Creation and Criticism?

Bai Yongrui:Because there are very few people with the surname "Bai" in Korea, some people speculate whether there is a blood relationship between me and teacher Bai Leqing. Actually, we are not related. Because of teacher Li Yongxi, I got to know teacher Bai Leqing. Teacher Li Yongxi was sued for "The Theory of Changing Times" and "Idol and Reason". As a publisher, Creative and Criticism Society made teacher Bai Leqing a "joint principal offender", but he was not arrested and put on record, but helped teacher Li Yongxi to join the lawsuit. So, I naturally got to know Mr. Bai Leqing.

At first, I worked as an editor in the Creation and Criticism Society, and later I participated in publishing as a graduate student and a university professor, which lasted for 30 years. I often think about my role in the creative and critical society. As an editor, an editorial board member and an editor’s main force, I have spent these thirty years.

I have reached the age of hearing. Looking back, my friends and colleagues who participated in the student movement all entered the field of political or social movements, while I, as a university professor and editor, have been dealing with books. For me, this kind of life choice is very consistent with my own endowment and meaningful. I am really lucky to be able to produce knowledge as a professor and a researcher, and at the same time to spread knowledge as an editor. Compared with the career as a scholar, the career as an editor is longer. From now on, I want to continue to work hard to do these two jobs.

From paying attention to water quality to paying attention to water ecology —— A direct attack on the "physical examination" of the Yangtze River

  Xinhua News Agency, Wuhan, May 13th: From focusing on water quality to focusing on water ecology — — The Yangtze River "big physical examination" hits directly

  Xinhua News Agency reporter Li Siyuan

  "This is a lake area, and there is a risk of contracting schistosomiasis. Don’t touch the water with your arms." At 2 o’clock on the afternoon of May 13th, in Dongting Lake, the middle reaches of the Yangtze River, under the reminder of colleagues, Han Tangrui, a post-90s monitor, pulled up the mud collector from the bottom of the water with his body close to the boathouse. The weight of 40 or 50 kilograms of mud collector and sediment made his face red.

  Han Tangrui comes from the Ecological Environment Monitoring and Scientific Research Center of the Yangtze River Basin Ecological Environment Supervision Administration of the Ministry of Ecology and Environment, and is also a staff member of the pilot monitoring of water ecological assessment in the Yangtze River Basin in the spring of 2023.

  In April this year, under the leadership of the Ministry of Ecology and Environment, the pilot monitoring of water ecological assessment in the Yangtze River Basin was launched in the spring of 2023. Monitoring personnel from the Yangtze River Basin Ecological Environment Supervision Administration and other units will comprehensively monitor the water ecology of 331 points in the main stream, key tributaries and key lakes and reservoirs of the Yangtze River from Qinghai to Shanghai within two months to find out the water ecological base of the Yangtze River and make a "big physical examination" for the mother river of the Yangtze River.

  According to the job requirements, the main task of Han Tangrui and his colleagues is to collect samples of macrobenthic invertebrates and zooplankton. "These creatures are important indicators of the health of water ecology. Macrobenthic invertebrates, although called ‘ Large ’ In fact, they are not big, some species are only a few millimeters in size, but they are very sensitive to changes in environmental conditions such as hydrology, water quality and climate, and are called ‘ Underwater sentry ’ 。” Han Tangrui introduced.

  In recent years, with the continuous promotion of the great protection of the Yangtze River, the ecological environment protection in the Yangtze River Economic Belt has undergone a turning point, and the ecological environment quality has been continuously improved. "The water quality is constantly improving, and the proportion of water quality section of Grade III exceeds 98%, which means that it is necessary to improve the health of the Yangtze River ‘ Portrait ’ In addition to using traditional physical and chemical indicators of water quality, we have to rely on higher-level water ecological monitoring. " Xu Yi, director of the Yangtze River Basin Ecological Environment Supervision Administration, said that China plans to take the lead in establishing a water ecological assessment mechanism in the Yangtze River Basin, and to establish this mechanism, it is necessary to conduct a comprehensive "physical examination" of the Yangtze River.

  According to reports, in order to more accurately grasp the water ecological status of the Yangtze River and lay the foundation for the water ecological assessment of the Yangtze River Basin, this year, the Yangtze River Basin Ecological Environment Supervision Administration added two indicators, namely river epiphytic algae and lake phytoplankton, to enrich the monitoring dimension.

  Xu Wei said that from focusing on water quality in the past to focusing on water ecological changes now, carrying out water ecological monitoring as the "big physical examination" of the Yangtze River is itself progress and innovation, which indicates that the main task of ecological environmental protection in the Yangtze River has shifted from water pollution prevention to equal emphasis on water ecological environmental protection and restoration.

Evaluation of old graphics card GTS250: Looking at the progress of 65/40/28 nm

  [PConline evaluation]Recently, the graphics card industry is full of news about GTX780, which is fascinating, but it is not something that ordinary users can consider. Let’s look back at the actual products. A series of old graphics card tests, we have been reflected by many netizens, this time we should test GTS250 at the request of netizens.

  The graphics card is called "GTS250", and familiar netizens know that this is the "mysterious" power of NVIDIA, which has changed from 9800GTX+. The specifications and parameters are just like 9800GTX+, and there is a significant change in memory. At that time, the core of NVIDIA G92 was old.

GTS250 evaluation

  After years of baptism, the high-end old cards many years ago are no different from the performance of general mainstream graphics cards. This time, we use another test method to see the performance differences of GTS250, GTS450 and GTX650. These three graphics cards use three different architectures and three different technologies, which also represent three different eras.

Comparison of three products with "5":

Graphics card comparison

  Although it also had a "5", GTS250 was launched in the mid-to high-end market of 999 yuan at that time, pushing HD4850. Similarly, GTS450 is also used as the mid-end market of 899 yuan, and HD6770/6750 is suppressed within 1,000 yuan. By GTX650, the market it faces has become the mainstream level, and this "5" has been devalued more and more.

  GTS250 uses the "G92" core which has entered dusk at that time (it has been used for three generations). Although the technology is a little old, its performance is still a bit worth seeing. When it comes to GTS450, using the mature Fermi architecture, the most brilliant period is not that it can suppress HD6750, but that the GTX650 introduced later is expensive, which makes GTS450 have a short spring. GTX650 is currently using NVIDIA’s most advanced Kepler architecture, with excellent energy consumption ratio, but the price is still slightly higher.

  If you want to know the positioning of the graphics card at that time, then it is most direct to look at the memory width. Due to the high cost of GDDR5 at that time, GTS250 still used GDDR3 video memory, with 256bit width and 64 texture units, which could not hide its high positioning at that time. As for the current GTX650, except for more stream processors, other parameters are relatively simple.

  This time, we received three graphics cards from Mingxin, which were used to test the performance and power consumption differences of these three graphics cards: GTS250, GTS450 and GTX650. These three graphics cards use the three-generation architecture of Trass, Fermi and Kepler respectively, and the three processes of 65 nm, 40 nm and 28 nm are also models with the word "5" in the middle. What will happen? We’ll leave right away.

  In order to unify the performance of the platform, we use the high-end 3770K platform to ensure that it does not cause system bottleneck, which is more convenient for the performance of the graphics card. We use the latest driver 310.14 beta at present, and add a new game "Subway: The Last Dawn". Of course, the games all choose DX9 or DX10 running mode.

Theoretical test scores:

  Because some graphics cards don’t support DX11, we tested 3DMark Vantage and the new 3DMark, and the results are for reference only.

  Test summary:Judging from the test results, the progress of the three graphics cards is relatively balanced. The score displayed by 3DMark Vantage, GTS450 is twice as high as GTS250, regardless of its accuracy, at least the detected result mainly depends on the graphics card. As for the Cloud Gate scenario of the new 3DMark, it is more about the performance of the platform.

● Popular game masterpiece test

  In order to make it easier for everyone to read, we have simplified the description of the game and compiled a variety of games into a big chart to make the comparison of the results more intuitive.

On the Significance of Game Frame Number (FPS)

  The number of game frames is a standard to reflect whether the game runs smoothly, which can be classified in most cases.No playability:The number of frames is less than 30FPS;;Acceptable:30-50 frames;Smooth operation:50-60 frames;Perfect operation:The number of frames is greater than or equal to 60. That is to say, under normal circumstances, the number of frames is greater than 60, which is of little significance. At this time, you can increase the quality of the game to get more visual effects.

Graphics card test

  Now many new games use DX11 interface, and we adjust most of them to DX9 or DX10 mode. From the test of the game, GTS250 is not as bad as 3DMark Vantage shows. At least GTS450 is not twice ahead of GTS250, and the performance of the three in the game is more like the performance of the new 3DMark.

  In addition, we also see that it is not impossible for GTS250 to play mainstream games in full HD resolution, but there is basically no enjoyment in image quality special effects.

Summary of evaluation results
GeForce GTS450 PK GTS250  +19% GeForce GTX650 PK GTS450  +21% GeForce GTX650 PK GTS250 +44%

  To sum up the achievements of the three graphics cards, the performance improvement of each generation is about 20%. We can guess that GTX750 may be 120% of GTX650, and perhaps GTX750 is a GTX650Ti vest (see GTX770 vest GTX680).

Platform power consumption test:

  Before the test, it should be noted that since the independent power consumption of the graphics card cannot be tested, all the power consumption scores in this round of test are the power consumption of the whole machine, and the power consumption tester is used for testing during the test. During the test, we run Tomb Raider 9 benchmark to test the average power consumption of the platform.

Platform power consumption

  Test summary:The technology is more and more sophisticated, the architecture is more and more advanced, and the power consumption is lower and lower. In the previous GTS250, the power consumption of the platform was 238W, while the GTS450 with stronger performance was 225 W. In Kepler’s generation, the power consumption was as low as 158W W.

  Compared with GTS250, GTS450′ s energy consumption progress is mainly achieved through the improvement of technology, and GTX650′ s performance is like this. In addition to the improvement of technology, streamlining general-purpose computing is also one of the means.

Summary of PConline evaluation room:

GTS250 ladder diagram position guide

Graphics ladder diagram

  PConline ladder diagram description:From the test, it can be seen that the performance difference between GeFoece GTS250 and GTS450 is about 20%, which is smaller than that of GTS450 and GT640. We define that GTS250 has better performance than GT640, as shown above in the ladder diagram.

● What is the value of ●GTS250?

  Looking back at GTS250, the listing price at that time was $149, which was close to 1,000 yuan at that time. What now? Although there are no new graphics cards, let’s go to the second-hand forum to see the current market.

Second hand price
The picture is intercepted in this forum (the value is also the best in 200 yuan)

  At present, GTS250 is probably worth 250 yuan. In four years, the value has shrunk to 1/4 of that at that time. Once again, we must feel the fall in price speed of IT products. With the performance of GTS250, you can still enjoy the game now. The price in 200 yuan is better than buying a GT630.

●GTS250 upgrade or purchase suggestion.

  At that time, with the GTS250 graphics card, most platforms used Xiaolong quad-core, Kourou E8400, or Kourou quad-core platforms. Compared with the current CPU performance, it is not bad, probably reaching the level of X4 740, and the performance can also be exerted with the current mid-range graphics card.

Upgrade suggestion

   For those friends who are about to retire from GTS250, we suggest to consider GTX650Ti, whose performance is far superior to that of GTS250, and its power consumption is lower than that of GTS250, and its energy consumption ratio is good. As for the friends who want to change to a new platform, according to the consumption level, they should buy the I5 grade at present, and of course they will match the GTX660Ti.

  The improvement of GPU technology and the update of architecture can improve the performance and power consumption of graphics cards, which will be reduced to 1/4 in four years. After four years, is HD7990 worth 2K? In the next issue, we will test the previous God cards, such as GTX295 and HD4870x2, and now the performance is equivalent to what price of graphics cards.
