In the '50s, inBeijing Institute of TechnologyMr. Chen Jing-min

　　The May Fourth Movement, which broke out at a time of national crisis, was a turning point between China's old democratic revolution and the new democratic revolution, and a milestone in the historical process of the Chinese nation's pursuit of national independence, development and progress in modern times。In the "five four hundred years", carry forward the great May Fourth spirit and forge ahead in the new era, we should not forget that among the teachers of Beijing Institute of Technology, there is such a "May Fourth pioneer" who "burned Zhao Jialou and beat Zhang Zongxiang".。He was Mr. Chen Jing-min (1895-1981), professor of Beijing Institute of Technology (now Beijing Institute of Technology), a famous mathematician and educator in modern China。

Patriotism for the people, "climb over the wall to hospital, beat up traitors"

　　Chen Jing-min, formerly known as Chen Hongxun, was born on July 5, 1895 in Tiantai County, Zhejiang Province, in a shop assistant's family. He studied private school and worked at home。In 1916, after graduating from middle school, Chen Jing-min was admitted to the mathematics department of Beijing Higher Normal University (now Beijing Normal University), from which he began his life with mathematics。

　　At the beginning of the 20th century, China was a weak country and poor people. Under the bullying of foreign powers, the Chinese civilization of 5,000 years had become a semi-feudal and semi-colonial backward country, and it was in turmoil in the international struggle against the strong of the jungle。From his hometown in Zhejiang province to the ancient capital of Beijing, Chen Jing-min broadened his horizons and gained knowledge, but he also saw the blight and darkness of society。Therefore, during his study, Chen Jing-min was determined to study hard to save the nation and revitalize the country, and became a practitioner of learning Mr. De (democracy) and an activist of Mr. Si (science)。

　　It was with this ideological awakening that Chen Jing-min soon joined the progressive student community in Beijing universities, actively engaged in patriotic activities and social service。In 1918, Chen Jing-min was elected as a member of the review Department of the National Magazine organized by the Beijing Higher Normal University and the Students' Union of Peking University。Soon after, he and other students such as Kuang Husheng and Xiang Daguang jointly initiated the establishment of the "Work-study Association" in Beijing Higher Normal University, which was later renamed the "Civilian Education Association".。

　　In 1918, as the victor of the First World War, China should have recovered the rights and interests occupied by Germany in Shandong and abolished the unequal treaties such as the "21 Articles", but the major powers decided at the Paris Peace Conference to transfer the interests of Germany in Shandong to Japan。China will be a "victor" identity, accept the "defeated country" treatment, the news came, the whole country is outraged。

　　Against this background, universities in Beijing scheduled a protest march on May 7, 1919, the day of national humiliation when Yuan Shikai signed the "21 Articles" of treason。Later, the news of the failure of the negotiations at the Paris Peace Conference continued to come, and the reactionary government was ready to suppress the march。The universities decided to hold a demonstration in advance on the morning of May 4, gathering in Tiananmen Square, and then protesting in the embassy area of Dongjiaomin Lane。

　　Chen Jingmin is the student representative of normal university，Take an active part，When the parade is blocked，Diverted to the traitor Cao Rulin's house in Zhaojialou，Facing the closed Cao family door，And the defense of the military police，The tall Chen Jing-min，Step on a companion's shoulder，Breaking a window facing the street，The first group jumped into the courtyard，Opened the door。

　　"At that time, Cao's family was closed, and many military and police were defending the area。Angry students piled on and hit each other with sticks, stones and bricks。Taller, I stepped on the shoulders of my normal school classmate Kuang Husheng, climbed on the top of the wall, was hit by the skylight, and was one of the first to jump into the Cao's courtyard。My classmates and I smashed the door lock and opened the door, so the students outside rushed in。We searched everywhere for Cao Rulin, but he and Lu Zongyu had long since fled。Only Zhang Zongxiang hid in the wardrobe in the side room, and we caught him out。He was pale, on his knees, and they were kicking and punching him half to death。Meanwhile, Cao's house was destroyed and the backyard was on fire。This is a memory of Mr. Chen Jing-min in 1979 when he participated in the May Fourth Movement and "burned down Zhaojialou"。

　　Subsequently, 32 people, including Chen Jing-min, were arrested and detained by the reactionary military police for failing to evacuate in time. During the detention, the reactionary military police severely beat and interrogated Chen Jing-min and others。Chen Jingmin's glasses were knocked off, his watch was broken, and his arms were bloody. He was locked in a prison cell with no food or water to drink, and classmates could not talk to each other。Until May 7, under the protest of the strike in various universities, after the running rescue of the school principals and patriots, the arrested students were finally released on bail, and were warmly welcomed by people from all walks of life in Beijing。

　　"The students who were welcomed were surrounded by neighboring residents。As soon as we got out of the car, he put on big red flowers, picked us up one by one, held us high, and took two pictures of us。The patriotic fervour of the masses was showered upon our captives。We can be released to return to school, this is the power of the masses, this is the victory of the people of the whole country, so that I was deeply educated, I will never forget。Sixty years later, in his article, Chen Jing-min recalled the scene of his release and still felt it vividly。

　　After his release from prison, Chen changed his name from Hongxun to Loymin at the suggestion of his school principal, Chen Baoquan, to avoid further arraignment or arrest。On May 7, Chen Jing-min, who had just been released from prison, returned to school and actively participated in the movement to boycott Japanese goods. As a representative of the Beijing Higher Normal School, he attended the Beijing Federation of Committees to Boycott Japanese Goods from all walks of Life, and was elected as the chairman and vice chairman of the Beijing Students' Federation。Subsequently, he actively organized students to take to the streets to boycott Japanese goods。

　　In 1920, after graduating from the Mathematics and Physics Department of Beijing Normal University, Chen Jingmin remained in the school as an attached middle school teacher and served as director of the accounting department of Normal University。In 1921, Chen Jing-min went to Lyon, France, where he studied mathematics while studying French at the French-Chinese University of Lyon。Later, because of the disclosure of the embezzlement of public funds in charge of the school, in order to avoid retaliation, transferred to the University of France to study。

　　

In the smoke of war, firmly education to serve the country

　　In 1925, Chen Jing-min received a master's degree in mathematics in France and returned to China to become a professor at Beijing Normal University and also a professor at Peking University。Chen Jing-min, who always cherished a patriotic heart, chose to serve the country with education and revitalize the nation。

　　Shortly after returning to China, Chen Jing-min applied to be the principal of Zhejiang No. 6 Middle School。However, when Chen Jing-min arrived at Zhejiang No. 6 Middle School, he was confronted with old buildings, dilapidated tables and chairs, and broken equipment。In order to quickly resume the operation of Zhejiang No. 6 Middle School, Chen Jing-min borrowed money to repair the school building and buy equipment. In only six months, the school was in good order。However, when Chen was offered another job and prepared to leave the school, the KMT education authorities found excuses to refuse to repay the 2,000 silver dollars Chen had raised for the school。Finally, starting from the overall interests of the country and the people, Chen Jing-min was willing to repay the loan by installments in order to protect the education cause in his hometown. He and his wife were frugal and frugal until two years later, when he joined Jinan University in Shanghai, they paid off the huge amount of money。

　　In 1937, after the outbreak of the Anti-Japanese War and the fall of Shanghai, Chen Jing-min and his family returned to Tiantai County, where education was backward. At that time, there was only one junior middle school in the county, which enrolled 50 students a year, and many teenagers in Tiantai and neighboring counties were out of school。Therefore, with the support of warm-hearted people, Chen and his wife applied several times to move to the rooftop of Shanghai Yuqing Middle School, which was founded by Chen's wife, Ms. Yan Zhenyu。Shanghai Yuqing Middle School was razed to the ground early in the war, leaving only the name of the school, the internal relocation is actually a new。Chen Jingmin and his wife personally planned to choose the school site, build the school building, purchase books and equipment and hire teachers。Later, due to the increasing number of students requiring admission year by year, the scale of the school continued to expand, and eventually developed to have more than 1000 high school and junior high school students, and set up urban and rural branches, township branches, Wenling County branch School in Zhejiang, a total of four teaching points。On the eve of liberation, this school trained more than 3,000 junior high school graduates, which played a positive role in solving the problem of youth schooling and improving the local cultural and educational level in Tiantai。

　　In addition to actively organizing basic education, Chen Jing-min also left his patriotic struggle in the history of modern Chinese higher education。In 1939, during the construction of Yuqing Middle School, Beiyang Institute of Technology decided to re-establish the school in Zhejiang, and hired Chen Jingmin as its president, but the location of the school was not determined for a long time。To this end, Chen Jing-min went around and finally decided to build a school in Baizhangkou Town, Taishun County, which was not occupied by the Japanese。At the beginning of the school, there was nothing, and the school had to rely on rented space to run the school, until 1943, a number of simple buildings were built。Due to the inconvenience of transportation at that time, Chen Jin Min personally contacted the construction of the school, often traveling hundreds of miles and crossing mountains。It is in his example of the spirit of hard work, the whole school teachers and students hard work, and finally made Beiyang Institute of Technology in Zhejiang re-opened。Chen Jingmin served his country with education and made contributions to the national War of resistance。

　　After the victory of the Anti-Japanese War, Chen Jingmin became a professor and dean of the College of Science at Beiyang University, and also served as director of the Beiping (Beijing) Department of Beiyang University。In the face of the reactionary rule of the Kuomintang, Chen was very supportive of the patriotic democratic movement of the students, often giving cover to the revolutionary actions of the students, actively rescuing arrested students, and explicitly resisting the entry of reactionary party groups into Beiyang University。On the eve of the liberation of Tianjin, the Ministry of Education of the Kuomintang urged Beiyang University to move to Taiwan. At the university committee, Chen Loymin and his colleagues strongly opposed it. At no risk to his own safety, he and eighteen professors jointly published an open letter in the Tianjin newspaper, demanding that Chen Changjie, the Kuomintang commander of Tianjin City defense, withdraw from Tianjin。On the eve of liberation, Chen Jing-min presided over the campus affairs of Beiyang University and actively organized staff to protect the school and prevent damage。After the liberation, he also served as the chairman of the Provisional Committee of Beiyang University。

　　

　Mathematics education, education for the country, ceaseless struggle

　　After the founding of New China, Chen Jing-min remained committed to the cause of education, training construction talents for the new China。In 1950, the Engineering College of North China University (the predecessor of Beijing Institute of Technology), which had just moved to Beijing from the liberated areas of North China, took the initiative to invite and introduce high-level teachers in China, expand the scale of the school, and raise resources for the establishment of a new socialist heavy industry university。In this context, Chen Jing-min came to North China University Engineering School as a professor and also served as a member of the school committee, began in such a new type of university, continue to deepen his love of mathematics, teaching people, for the country to cultivate the pillar of the talent。

　　Chen Jing-min, who taught all his life and had deep academic attainments in the field of mathematics, was a famous mathematician and educator in modern China。As early as when Chen Jing-min studied in France, he had a strong interest in "non-European geometry" and carried out in-depth research。After returning to China, while teaching at Beijing Normal University and Peking University, Chen Jing-min wrote a book called "Non-European Geometry" in English to introduce this new subject to students。Later, he re-wrote and revised this book in Chinese, and published it in the Commercial Press, where it was listed as one of the university series. Chen Jingmin made an important contribution to the research and education of modern mathematics in our country。

　　As an influential mathematics educator before liberation, Chen Jing-min was knowledgeable, rigorous in his studies and distinguished in his achievements. He not only taught more than ten higher mathematics courses, but also edited his own lecture notes and translated a large number of foreign mathematics literatures。After liberation，Chen Jingmin once chaired the Mathematics Teaching and Research Group of the Engineering School of North China University (the predecessor of the Department of Mathematics of Beijing Institute of Technology)，He attaches great importance to theoretical research and teaching，Combine theory with practice，Effective teaching，Rich in experience，Be humble，Lead by example，Caring for young teachers，Bring out a team of high-quality teachers，It lays a solid foundation for the development of mathematics discipline and personnel training in our school，Make an outstanding contribution。

　　In the late 1950s, Chen Jingmin was also employed by the Ministry of Education as a member of the national Engineering mathematics textbook Editing Committee, and his Higher Mathematics Course was listed as a general textbook for engineering colleges and universities in China, making outstanding contributions to the construction of engineering mathematics textbooks and the formation of mathematical models。During his lifetime, Chen Jingmin published nearly 100 kinds of higher mathematics textbooks and middle school mathematics textbooks, and published a large number of academic papers。

　　"Mathematics is one of the fundamental sciences，It is the most important foundation of modern science and technology，It's the foundation of the foundation，The study of basic theory can not be separated from mathematics，Therefore, the science and technology level of our country should be improved，We should strengthen the study of mathematical theory，In particular, we should strengthen the research of engineering mathematics and applied mathematics, which are the weak links in Chinese mathematics。In early 1973, during the Cultural Revolution, despite the impact of the movement, Chen Jing-min remained committed to the cause of the Party and the country, taking political risks, in a letter to Premier Zhou Enlai on strengthening mathematical research。Premier Zhou took the letter seriously and instructed his office to call Chen Jin Min and ask him to make a list of domestic experts in the field of applied mathematics。

　　In 1978, the country implemented reform and opening up. At the age of 83, Chen Jin Min still devoted himself to his work with full enthusiasm. Although he could no longer teach in person, he cooperated with others to rewrite Basic of Higher Mathematics and other textbooks with the support of the Party Committee of the university。"The book information can not be completely spread out, it is more difficult to find information, but I sat on the sofa in front of the self-made simple coffee table, wearing glasses and magnifying glasses, and finally overcome all kinds of difficulties, and successfully carried out the work of writing and reviewing.。This is a self-statement of Chen Jing-min who is still in charge of writing textbooks at the age of 80。

　　In 1981, Chen Jing-min died in Beijing at the age of 86。

 

　　"Over the past 100 years, Chinese youth, full of pure heart for the motherland and the people, have actively engaged in the great cause of revolution, construction and reform led by the Party, fought for the people, devoted themselves to the motherland, and fought for a happy life, dedicated their best youth to the motherland and the people, and composed one magnificent song of youth after another.。”习近平总书记在纪念五四运动100周年大会上的讲话中这样讲到。

　　Over the past hundred years, the spirit of the May Fourth Movement has been passed on endlessly, and patriotic struggle has always been the main theme of Chinese youth in every era。新时代，紧密团结在以习近平同志为核心的党中央周围，发扬伟大五四精神，奋力谱写实现中华民族伟大复兴中国梦的壮丽篇章，更需要青年一代高举爱国主义伟大旗帜，追求真理、追求进步，继承弘扬永久奋斗的伟大传统。In the great journey of building a world-class university with Chinese characteristics, the young teachers and students of BEIT, who love their country, strive and pursue their dreams, keep moving forward!
