Chapter 7 Section VI

Judging from the data, Ye Qisun has been obsessed with mathematics and science since he entered Jingye School, but after entering Tsinghua School, his hobby became more obvious, and he was regarded as a higher level of improvement. Ye Qisun stepped into the door of science, and mathematics seemed to be the "key" to his enlightenment.We can't describe why those boring numbers give a teenager such happiness in an abstract and logical world.Even if he scribbled on the blackboard randomly, he was able to have a flash of inspiration, "Suddenly thought of the solution to the problem of finding a triangle with two midlines and vertices."He wrote in his diary on December 17, 1915:

I have been obsessed with mathematics for the past few years. During this year, outside the school schedule, most of the miscellaneous works on mathematics I wrote are scattered in my diary, and I forget as I write... Ye Qisun listed the math problems he had done in his diary one by one. Those math problems were not arranged by the teacher, but he searched them deliberately.Diligence and perseverance make Ye Qisun like a farmer who hoes and works all day long. After plowing and watering, he must remember to understand the essentials and methods.Tsinghua University is rich in relevant materials, and Ye Qisun greedily gallops in the kingdom of mathematics. With the help of the two wings of creativity and imagination, he sometimes roams in ancient times and sometimes flies in the present.

On October 2, 1915, he wrote in his diary after calculating the fifth question of "Qinlujun Mathematics Book Nine Chapters Tian Yulei" "calculating the product of banana leaves": According to the museum, there are very few subjects in this question, so the number obtained is more than 700 more than that of the ancient method, and more than 2,700 less than that of the esoteric method.If the length is set to be 707 and the width to be 293, and it is also calculated according to Qin's method, more than 30,426 steps can be obtained as the land plot.According to the esoteric method, there are actually more than 144,900 steps, the difference is very far, and the discrepancy between the numbers is obvious.The number must be multiplied three times and then it can be squared to find it. Now after multiplying it again, it can only be calculated by decimals, which should not be used.

When calculating the seventh question of "Yuanying Measuring Rain" in "Qinlu County Number Book Nine Chapters·Tianshilei", the result he calculated was not consistent with the original one. He recorded in his diary: According to this number and the original answer, I recalculated many times, and the result was more than three feet and five inches, which was completely different from the original answer of one foot and eight inches.Ask yourself that the algorithm is reasonable and cannot be wrong.Gu Cunzhi, a gentleman in this world may be able to see and make mistakes.Otherwise, it will be left to future generations.

Not long after, he confirmed his judgment in another reading, so he added: A few days after I made this grass, I checked "Song Shi's Notes" by chance, and I knew that my answer was correct.Shen Shi cited the library as saying: "This question is superfluous in the sentence 'the depth of rain on flat land has nothing to do with the density of the circle'. If you want to ask for the accumulation of rain in the poppies, you should add this sentence." Inch and 920/1323" (that is, 23,000/33075, combined with the recipient). Anyone who is familiar with modern cultural history knows Qian Xuantong's mental journey from "believing in the ancients" to "doubting the ancients" and then to "interpreting the ancients". Wait, have had similar experiences.And behind this phenomenon is actually relying on the introduction and infiltration of heterogeneous culture or foreign culture, and re-examining Chinese traditional culture with the help of this "third eye", and then absorbing or sublating it.Most of the people who have received western education and influence of western culture have this distinctive cultural identity, and use this unique cultural perspective to observe the past history and culture, what to pursue, what to explore, what to question .After a process of eliminating the false and saving the true, we will collect the essence of the traditional culture of the motherland in order to enjoy it slowly.This is true of Gu Hongming, Chen Yinke, and Lu Xun and Hu Shi.They didn't know the present and the evening because they stayed abroad for several years, and they didn't forget their ancestors because of their familiarity with foreign languages. Because of their experience of studying abroad for many years, they became the "third type" of people, that is, between Chinese and foreigners. They are not only Chinese, but they are also different from Chinese in the traditional sense because of the influence of Western education and Western culture.In the field of natural science, Ye Qisun was proficient in arts and sciences, and became a pioneer in this period who asked the door of ancient mathematics and science.

With a solid foundation in mathematics and science, Ye Qisun's vision is broader.His father's admiration for Western science deeply influenced him. His eyes kept searching and exploring in the field of science, and he really fell in love with it. On January 10, 1915, a science and education film about the discovery of geological structures was shown in the auditorium of Tsinghua University.Ye Qisun watched it with gusto, but there was snoring from the next seat. Ye Qisun felt it and wrote down the following words in his diary that day: Evening movies, lectures on geology, high-level subjects, few listeners, although there are many middle-level subjects, they can't understand, the interest is dull, and they don't feel tired and snore.The ignorance of scientific common sense among our students can be seen here.In the preface of his speech, he first talked about the types and their formation on the earth, and finally attributed them to igneous rocks.But where do igneous rocks come from?It talks about the division of the earth from the sun and the relationship between the earth and the eight planets, that is, the theory of Copernicus' solar system, and the theory of the air mass of the lost sun.At the end, I will talk about the ancient creatures, which have evolved into the present form through natural evolution. The general direction of change is that the intellectual development is becoming more and more developed, while the claws and teeth are gradually being eliminated.From this point of view, a certain country only focuses on armaments, which is in line with the laws of nature, and its meaning is also criticized by Germany.It is also said that students such as you should pay attention to the understanding of science, to explore the secrets of the world, and to seek the happiness of the people, so that the few countries will advance day by day and the race will not be eliminated.

I remember that when Lu Xun was studying in Japan, he also saw in movies that outsiders abused Chinese while Chinese classmates were insensitive, so he abandoned medicine and embarked on the literary road of healing the souls of the people.But Ye Qisun saw another defect of our nation in the same situation, and realized his own responsibility: "Students like you should pay attention to the understanding of science, in order to explore the secrets of the world, to seek the happiness of the people, and the future of the country. To advance to no strength, the race will not be eliminated." Such a clear understanding is really commendable for a young man with a weak crown.

After the summer vacation in 1914, shortly after Ye Qisun returned to school from Shanghai, he and his classmates raised funds to establish the "Science Society".In Tsinghua University at that time, various associations sprang up one after another, which can be described as splendid, showing its inner vitality.Since 1911, there have been "English Literature Club", "YMCA", "Dade Society", "Singing Troupe", "Photography Troupe", "Art Club", "Science Club", "Literary Friends Club" Society", "Physics Research Society", "Agricultural Society", "Real Society", "Ci Society", "Entertainment Society", "Confucian Society", "International Research Society", "Mingde Society", "Bicycle Club" and "╩社" and so on.

Students have many motivations to join clubs, some are lifelong wishes, some are chasing trends, and some are caused by the unique spirit of youth.For example, the "╩ Society" was founded by Pan Guangdan, Wu Zelin, Wen Yiduo and other friends. Because they were dissatisfied with the school's continuous screening of scary and frightening thrillers, they gave their opinions to the school. Videos that waste time should be played less.But other students held objections to their move and claimed that they were a group of monsters.Therefore, Wen Yiduo and Pan Guangdan told a few friends that since they called us weirdos, we should organize a "╩ society". "╩" is an ancient character, that is, the word "shang", and it is connected with "shang"; the simple and simple Shuimu Tsinghua should not be eroded by the decadent and sluggish atmosphere. "...This society controls everything. If the movie is not good, we criticize it. If someone goes to the toilet and does not obey the order, and piss and pee outside, we also control it." Series 71, p. 200) This "╩ Society" had only four people at first, and later a few students joined, and there were only seven or eight people.

In comparison, the "Science Society" founded by Ye Qisun has a lot of important people.The reason is that in the hearts of Tsinghua students, the word "science" has been deeply rooted in the hearts of the people, and everyone yearns for it, so they flock to it.Ye Qisun has understood the family motto of saving the country through science since he was a child. Moreover, he likes to read historical materials and classics, and pays special attention to articles related to science and technology.When he came to Tsinghua University as a student, with the broadening of his horizons, the connection between the trend of world development and science and technology has been clearly presented before his eyes, and the rise and spread of science is no longer a matter of a single individual , it depends on the impact of groups and teams.Therefore, Ye Qisun proposed that "it is better to set up a society for servants", and called on everyone to "gather hundreds of handsome people, with the same purpose, daily dipping, learning and pondering; specialists, engaged in research... After a long time, there must be outstanding ones. The ones are out of the way."These views of Ye Qisun later became the theoretical basis of the "Science Society" and the programmatic opinions for its establishment.It can also be said that Ye Qisun's views represent the development direction of Tsinghua students in line with the times. Therefore, the "Science Society" has spread continuously for a hundred years, and later developed into an academic society with national influence.Later, when Ye Qisun turned his attention to the study of the history of science, we suddenly discovered the connection between the history of science and the society of science.The history of science often does not only examine and study individual cases, but is often more interested in team phenomena under the conditions of the times.

Ye Qisun has always been devoted to the study of the history of science in China. In his early papers, such as "Research on Shanggong" ("Journal of Tsinghua University", Vol. Volume No. 6), etc., can be said to be the earliest historical works that use scientific methods and modern mathematical knowledge to introduce and discuss the history of Chinese mathematics.Afterwards, the research and inquiry about the history of Chinese science has always been in his heart, until his death. It is said that Ye Qisun has been devoted to the study of the history of science all his life. A good proof is his friendship with British scholar Joseph Needham.Needham was born in 1900, two years younger than Ye Qisun.He was originally a biochemist, and was once among the ranks of British academicians by virtue of embryology research. In 1936, he became interested in China by chance, and learned Chinese and read ancient Chinese entirely by self-study. In 1942, the British government sent a scientific mission to China to boost the morale of Chinese intellectuals during the war of resistance.Needham was nominated by the Royal Academy and served as the head of the regiment.At that time, Ye Qisun was the director-general of the Academia Sinica and presided over the daily affairs of the Academia Sinica, so the two got to know each other.At this time, Needham's interest had completely shifted to the study of the history of Chinese science. In order to focus on this research, he applied to the British government to stay in Chongqing after the mission of the mission was over, and became the scientific counselor of the British Embassy in China.During his stay in Chongqing, Needham and Ye Qisun had many contacts, and the two went to the surrounding areas of Chongqing together for scientific investigations many times.At this time, Joseph Needham represented modern western scientific concepts. After being baptized by a series of theories of Newton, Copernicus and Einstein, he focused his thinking on ancient China, looking forward to finding new ideas in the hometown of the four great inventions. to more scientific discoveries.His efforts have been rewarded, in addition to the four great inventions, he also developed more and longer lists, such as crossbows, stirrups, water clocks, longitudinal rudders, segmental construction arch bridges, leak-proof bulkheads, Sailing with schooners, pig iron, blast furnaces, etc.But, more important than these discoveries, he discovered the greatness of China. At the Chongqing wharf, at the confluence of the Yangtze River and the Jialing River, Ye Qisun told Joseph Needham about China's Heluo culture in the reverie where the turbidity and clearness meet.That is the Central Plains thousands of miles away. When the sun sets, at the confluence of the Yellow River and the Luohe River, one water is like gold, and the other water is like silver. Mysterious picture.This is the original source of Taiji diagram.Ye Qisun told Joseph Needham that in Yuli City, which is in the shade of Tangshui, "Wen Wang imprisoned and performed "Book of Changes", Zhou Wen Wang deduced the sixty-four hexagrams from the eight hexagrams, and used the length of yarrow to deduce the relationship between human beings, time, space and The relationship between society and nature is compared with the natural and mysterious filing system to compare the passing of the sun and the unpredictable world. Using typified symbolic means, the classification method is derived from the combination of long and short, positive and negative, and yin and yang, presenting a A universal force changes with the period, and thus conceives a set of nearly complete cosmic system for monitoring.Behind the birth of these things is the amazing imagination and poetic soul of the Chinese nation.This is the characteristic of the development of science in ancient China.While some discoveries lack scientific proof, the gaps are partly bridged in a spout of poetic imagination.Needham lacked knowledge of Chinese classical literature, and many classics, such as the number of sands in the Ganges River, are rare even if he spends his whole life studying them.In this regard, Ye Qisun gave him a lot of help.Needham was amazed by Ye Qisun's knowledge. Ye Qisun was a scientist, but he also possessed so much knowledge outside his major. In a sense, knowledge outside his major often determines the success or failure of his career.Therefore, whenever he travels, Needham always loves to accompany Ye Qisun. On the truck they ride together, there are historical fragments similar to wooden cows and horses they collected in the countryside and the ingenious inventions of local craftsmen.The long journey became a seminar for the two to discuss the history of ancient Chinese thought and science. They talked about Zhu Xi and Einstein, and talked about "Tiangong Kaiwu" and "Shui Jing Zhu".In the violent bumps of the mountain road, Eastern and Western cultures will also collide with each other.Needham would hear Ye Qisun's subtext from his calm narrative.Joseph Needham brilliantly pointed out that in China's judging of history and science, there is often a state of confusion between ethics and physics, such as Cai Jing's calligraphy in the Song Dynasty.China does not have a set of strict academic standards to treat history and science, and it often varies from person to person, so it is difficult to present the original appearance of history and science. Therefore, the pace of science is still at the stage of the Middle Ages... In such exchanges, Ye Qisun Also benefited a lot.The perfect goal of a true scientist is thus gradually established. Many years later, Needham's "History of Science and Technology in China" was published.On the title page of the physics volume of the book, Needham wrote affectionately: Dedicated to Professor Ye Qisun. "Journal of Tsinghua University" was founded in the autumn of 1915, "...it is named after its scientific name, so the selection of manuscripts is extremely strict. Anything that is not about "scholars" such as novels is not published. Therefore, every time it is published, the content is very impressive, and it is very popular with the outside world. , spread far and near, and has a very wide market."At that time, the headmaster of the journal was Mr. Zhou Yichun. The editor, manager and consultant of the journal were hired by Mr. Zhou himself. Tang Yueliang, Chen Zhen, etc.As for Ye Qisun, he should be the first to be hand-picked among Tsinghua students, and he deserves his name. As early as 1914, Ye Qisun, who was only 16 years old, completed the academic paper "Correcting Shang Gong", which was published in the "Journal of Tsinghua University" two years later.Ye Qisun wrote in the article: This article is an old work two years ago, and I am ashamed to be superficial after reading it recently.Learning to calculate is advancing with the times, and there is no limit to it.However, "Shang Gong" is one of the "Nine Chapters", the quintessence of Chinese culture, you must know it.The original text is full of ancient meaning, and the later commentators, their writing is also elegant and tame.In this work, the title technique is still the same, and the reasoning strives to be elegant.Let readers know that our country's mathematical characters have their own good ones.Among the students who study solid geometry, they can know the consistency of Chinese and Western principles.The calculation formula respects the example of Haining Li, so as to see the changes in the past sixty years.As for the argument, repeated extensions, lest they be exhausted, will benefit scholars' thinking. After reading it, Mr. Mei Yiqi commented happily: "Ye Jun's questionable works are all due to the error in the original book's phrase 'the young children's pans, ponds, valleys, all are rectangular bottoms, and all are truncated cones'. However, Ye Jun can It is gratifying to speculate repeatedly and expose its mistakes, and the reasoning is comprehensive and the arrangement is precise, all of which can be seen from the heart and uniqueness..." On October 11, 1916, Ye Qisun published an academic paper "Ge Gu Jie Jie" in the 82nd issue of "Tsinghua Weekly". After reading it, Mr. Rao Luqiao, a Chinese teacher at the time, commented: "Don't follow the words of the annotators, but use your own essence. It is appropriate, it is difficult, since there is no source of learning, I can achieve this." On October 25, 1916, "Tsinghua Weekly" serialized Ye Qisun's long essay "A Brief Introduction to Tianxue".In this long article, Ye Qisun casts his thinking eyes on the vast space, from Copernicus's heliocentric theory, Galileo's principle of relativity, Huxley's theory of evolution, to the "Historical Records" of the Official Book of Heaven, "Han Astronomical Chronicles of "Shu" conducted a rational exploration of its theory of earth circle and earthquake, which should be a scientific astronomical question in the modern sense.For some reason, from the perspective of our country's literary history, everyone who asks the sky always has compassion, sorrow and anger.Qu Yuan was like this, Ye Qisun was like this, and a few years later, his disciple Zhao Jiuzhang, who was deeply influenced by him, was also like this, an atmospheric and geophysicist who had been engaged in heaven and earth all his life.He died unjustly during the "Cultural Revolution", and even his body was not found. This is a later story. In December 1916, Ye Qisun published "A Brief History of Chinese Mathematics" in the sixth issue of the second volume of "Journal of Tsinghua University". After Li, he summarized the mathematical achievements of famous mathematicians Shang Gao, Liu Hui, Zu Chongzhi, Wang Xiaotong, Qin Jiushao, Li Ye, Li Shanlan, Hua Hengfang and others in the history of our country, and said in the conclusion: "Those who are good at reading history , observe the gains and losses of the past, and seek future progress." He suggested that the establishment of the Mathematical Society should firstly carry out systematic research, and secondly, pay attention to the teaching trends in various countries in the world, and use the comparison between China and the West to catch up with the advanced countries in mathematics.It is precisely because of Ye Qisun’s vision and mind that when he was the dean of the Tsinghua School of Science, he was able to exceptionally approve Mr. Hua Luogeng, who had only a junior high school education from Jintan, Zhejiang, to stay in the school, and supported him in many ways, eventually making him an international student. well-known mathematician. When Ye Qisun was still a student, many of his academic works had been published in prestigious foreign magazines.He established a fixed academic relationship with the American "Science" magazine very early.Domestic Commercial Press and Zhonghua Book Company also often asked him to translate foreign academic articles. In the minds of some editors, they thought he was a senior editor of Tsinghua Journal at that time, or a scholar engaged in academic research. Ye Qisun founded the Science Society of Tsinghua University and served as the president of the Science Society.When he joined the society, he donated 49 volumes of mathematics books and other books to the Science Society for the study and research of fellow students.In everyone's mind, Ye Qisun took the path of a scholar.The Tsinghua people once divided students into several factions, one of which was called the "Scholar School", which reads like Ye Qisun's deeds, here is a good read: The characteristics of a scholar are not only studying hard, not only getting good grades, but also being able to seek real knowledge.Half of their happiness is found in books or laboratories.There was little love life or friendship life between them, and they engaged in other activities now and then, but they considered learning to be their life's work.They are the most familiar with the books in the library.They often borrow the library cards of many classmates.In the library and dormitory, they are often seen holding a thick extra-curricular book with their heads down, and taking notes with a pen.A thick volume of notes was bound, which was their greatest treasure.They also acquire the "scholar" attitude.When a problem arises, it is necessary to find a definition before discussing it.Some people talk about love life, and they have to put forward the definition of love very rigidly.Sometimes they are reluctant to express their opinions easily, and have to wait to check the reference books before making a judgment.This kind of scholars do have their own happiness. As long as they have time to read more books and acquire more knowledge, they will be satisfied.Every time I finished reading a book, I stood up and stretched, and returned it to the library in a hurry, feeling extremely happy.Even if they want to find other books to prove it.Occasionally, he has some good opinions on his own initiative, and he will write them down immediately... Some people study psychology, and are especially interested in "abnormal life" and "psychoanalysis".Some study political science and actually want to formulate constitutional claims.Some research education, in addition to reading, they also taught many children to practice "experimentalism".Some also study Einstein's "Theory of Relativity" and Russell's "Philosophy of Mathematics".They were very happy to see Einstein's refutation of Newton's theory; they were also satisfied after spending several days understanding a formula.There are also those who have a strong relationship with the experiment.I went to the laboratory before it opened, and left after class.Eating is a trivial matter, and they are willing to sacrifice. Sometimes they bring chocolate candies into the laboratory, and they go in in the morning and come out in the evening.They find great joy in learning. Of course, this is a common portrait of Tsinghua scholars, not only Ye Qisun.But Ye Qisun is indeed the kind of person who seeks happiness in learning. When Ye Qisun was in Tsinghua University, in addition to participating in the "Science Society", he also participated in another society "Mingde Society". Members included Cao Mingluan, Ling Qijun, Zhang Kezhi, Qu Guojuan, Xu Zhenzhou, Tang Chongci, Wu Mi, Chen Qi, Yu Zelan , Wang Shanquan, Liu Zhuang, Dong Xiujia, Cha Liangzhao, etc. In the 1910-1915 volume of "Wu Mi's Diary", there is a photo of the club when it was established. 18-year-old Ye Qisun was wearing a green cloth gown and sitting among his colleagues. Behind him on the left was a thin man wearing glasses. The person is Wu Mi. The so-called Mingde society is taken from the first chapter of "University", "The way of the university lies in Mingde, in being close to the people, and in ending in perfection", which means to demonstrate virtue and achieve a perfect ideological realm. In China, there are profound reasons why Confucian classics have been respected and trusted over a fairly long historical period.From birth to growth, a person "trees naturally straight".Education plays an immeasurable role in a person's childhood and adolescence.In this regard, Confucian classics have won the respect of the Chinese nation for thousands of years.Its ethics have penetrated into all levels of society, and even every family.The country and the nation are uniformly regulated and admonished, led and advised by this culture.From the perspective of cultural history, there may never be a culture as successful as Confucianism in the world.Ye Qisun was led by this kind of culture, to be a student with whole personality wholeheartedly, to become a perfect person. In the summer of 1915, Ye Qisun returned to his home in Shanghai on vacation. Since his father had gone to Tsinghua University to teach at this time, only the elder brother and the second brother were left in the family. The brothers had too many things to do, and they didn’t care about housework. mean.Ye Qisun is the third son. It is said that the family has the eldest son and the second elder brother. He turns a blind eye to everything, but Ye Qisun has the heart of family and country. If you don't even love your family, how can you love your family and your country?So he put down his studies and was busy with housekeeping during the holidays. He didn't pick up his studies until he finished handling the chores at home.We can learn this detail from his letter to his classmate Su Min on July 24, 1915: Brother Su Min’s Great Lesson: The day before yesterday, I read the handwriting, and learned that Beijing and China have been raining day after day, and they have become Zeguo.Although my younger brother is in Shanghai, this kind of heart does not mean that I am depressed.The scorching heat here is slightly reduced, and I don't want to have the hardships of last year. Although it is said that the sundial is long in summer, but my brother is busy every day, it is a pity that the busy person is not academic, but the political ear of the family.In recent years, Gai's family members are all tourists, so there is no one to clean up.Since the younger brother returned home, it was difficult to blame himself.For ten days, I have sorted out the old things of the book, hiding those that can be hidden, discarding those that can be discarded, destroying those that are broken, and exposing them to those who are moths.That is to say, in terms of books, it takes many days to catalog by division. Besides, the rest are so busy all day long that they have no time to sundial.Although it is said that I don't care about family matters, I am actually a humble husband, so how can I... Ye Qisun often said: When children go out, they will not leave their father and brother to worry about them.He also transcribed Fang Xiaoru's words to discipline himself: A brother must love his brother, and a brother must respect his brother.Don't hurt the flesh and blood with the slightest profit.It can be seen that the reason why Ye Qisun is strict with himself and lenient with others is the result of his strict compliance with Confucian principles. Ye Qisun has been gifted since he was a child, and his intelligence is comparable to others.Generally speaking, this kind of ice-snow and smart people probably don't get along well with others, but Ye Qisun is not like that. In his youth and youth, he was always surrounded by friends.He himself has no desire to be a leader, nor does he want to be a center.He was always so modest, courteous, upright and honest, so he was loved by his friends. In his diary, there are many articles talking about the situation with his former classmates.Some of the classmates he associates with are rich and poor, and he treats each other with sincerity.He took the love of his classmates very seriously, thought about it in his heart, and recorded it in his diary, showing his concern for his classmates. After his classmate Zhou Yunjie visited, he wrote in his diary: Zhou Yunjie came.Jun is a graduate of Yangzheng, and was promoted to Songjiang Middle School and Suzhou Higher School.Xin Haiqiu dropped out of school and returned.Previously taught English and Chemistry in Yangzheng, Wuben, and Pudong Middle Schools.However, your heart to learn is still not fading.Last summer, I was admitted to the science department of Peking University.You have personally held the teaching whip, so when he speaks, listens, and teaches time, the more dedicated his heart is, the more he learns.Nai's family was poor, so he could not continue to study.I will be teaching again next semester! When he learned of the news of the death of his dedicated classmate Pan Zhongkai, he felt very sad, thinking about the past, and expressing emotion: Pan Junzhong, who tabooed against Wei Yu, sat up (house) in three weeks, and went to salute.Pan Jun is a dedicated graduate. He passed the entrance examination of Tsinghua University in the third year of Jingye, and then separated from you. Unexpectedly, in the first year of the Republic of China, you died of an epidemic at the age of nineteen.Jun looks amiable and amiable, good at calligraphy and painting, and has a deep family education, so I don't see it growing in calligraphy and painting.Jun Wen is elegant and can be recited.Xijun's protruding eyes and short jaw are not a tool for longevity, but his death has not completed his studies.Oh, it hurts! Another classmate, Li Jingpeng, was born in a wealthy family. Because he was the only son, he was spoiled and spoiled since he was a child.Fearing that going to school would be a waste of time and energy, his parents let him sit idle at home.Who would have thought that classmate Li would mix with the dubious people in the society, get involved in all kinds of bad habits, and even develop to the point of taking concubines.Ye Qisun was very sad to see his former friends who were willing to fall into depravity, and once accompanied another classmate Zheng Xinji to persuade him.He recounted in his diary: Visited Li Junjingpeng with Zheng Junxinji, wanted to warn him, but unfortunately did not meet.Graduated from Jun Jingye, he was transferred to a private middle school. Within a year, his mother thought that he would have no peers, fearing that he would die if he was eager to learn, so he ordered him to drop out of school. Now he has been living at home for two years.Unwilling evil thoughts are born from laziness.Since you live at leisure, a friend of yours lured him to travel north. Once he fell into a rut and couldn't shake himself up, now he doesn't go there every day, and he is not happy every day; Harm can also be feared.I recently heard that the king will take concubines, but the mother will not allow them, but there is no way to stop them, so I plan to ask the father to intervene.Yu's family and Jun's father and ancestor have been friends for several generations, and the friendship lies in the meaning of An De's resignation. Because of Zheng Jun's auspicious return, it is a pity that he does not meet him.The way home is boundless, and my heart is not at ease. I am determined here, and I will talk about myself in the mirror. Because I did not meet Li, Ye Qisun felt that he had not fulfilled the responsibility of being a classmate and making friends, and felt uneasy.Even though he returned to Tsinghua University, he still cared about it, so he wrote to Zheng Xinji, asking him to visit and persuade Li, so that Li would wake up early, and at the same time relieve his worries: Brother Xinji: After the meeting in Shanghai, I left in a hurry, and I didn't have time to leave. There was a postcard sent to my foot, and I understand that it has been read.My younger brother arrives in Beijing on the 5th, enters the school on the 8th, and starts class tomorrow.Li Junshou's elder matter, did you ever go to persuade him?A friend's rule is that the most difficult thing to do is also the most important thing. I hope that I will encourage you to do it. It is not the virtue of one person alone. It is also Li Jun's infinite luck... Ye Qisun cares about people, like the spring breeze turning into rain, refreshing, always touching people inadvertently.Sometimes I write a letter to a friend, but I can touch several friends with affection, and my heart is far away.We can see his delicate emotions from his letters with Su Min: Brother Su Min Yalan: I received the film before, but I have already left Beijing.My younger brother intended to meet you again when you return to Beijing, but now you can't.The gathering and parting of life is inherently fixed.Qing school starts tomorrow, my brother has been at school for 5 days, before the class starts, I think it is boring.The homework in the next semester is very light, only English, German, Western History, Solid Geometry, Biology, and Chinese.I haven't read biology, so it's very interesting to open the book.Youhua can arrive at the school today, and the university officials can also come one after another. The geologists have not yet returned from Beijing. Do you know where they corresponded?Shen Junyi has been admitted to the liberal arts of Peking University.My younger brother met with you before, and you threatened to say, "I didn't take Tsinghua University in the first two exams, but now I have taken the university."Wei Qiyan is quite arrogant in the daytime.When you read my book, you should think of the interesting story of Xuansan in the Songjiang Pavilion, but Shen Jun's attitude has not changed. The acquaintance of our generation in the United States, Fan Jun died before him, and hereby heard the sad news of Gan Jun Chunqi. Although Gan Jun is suspected of running away, he does not seem to have died young.The world is like a dream, not only the sudden birth of Gan Jun, the sudden study abroad, the sudden illness, and the sudden return to the dead, as in a dream, that is to say, when we hear the bad news of the king, it is also like in a dream... In this way, during the five years of studying at Tsinghua, Ye Qisun not only enriched his knowledge, but also plumped his wings. He became a student with a "whole personality" required by that era, and ended his student days in Tsinghua Garden that influenced his life with excellent results. .
