125 years ago today, on February 25th, 1900 (January 26th, 1900 in the lunar calendar), Qian Duansheng, a famous jurist, was born. Qian Duansheng, whose courtesy name is Shoupeng, is a native of Caoxing Township. Born in Shanghai on February 25th, 1900. Qian's ancestors practiced medicine and were diligent and studious. At the age of 13, he went to Jiangsu No.3 Middle School (Songjiang Middle School). In the autumn of 1916 (the 5th year of the Republic of China), he entered Nanyang Middle School in Shanghai, was admitted to Tsinghua School in Beijing at the age of 17, and was selected to North Dakota State University at the age of 19. He soon entered Harvard University Research Institute for further study, and received his doctorate in philosophy at the age of 24. After returning to China in 1924, he served as a lecturer in Peking University and Tsinghua University, teaching political science and constitutional law. At that time, imperialism was rampant in China, and the concession was particularly sinful. Duan Sheng was saddened by this. In 1927 (the 16th year of the Republic of China), he taught at Nanjing Central University, and published continuous expositions in Modern Review magazine, strongly demanding the abolition of "consular judgment" and the return of the concession; And advocates learning from western experience and establishing a perfect Chinese administrative system. In 1930, he returned to Tsinghua to teach and concurrently served as a teacher at Peking University. In 1934, the Japanese aggressive forces advanced on North China, and the National Government stepped up its "cultural encirclement and suppression", and the national crisis became urgent. Luo Longji, the chief editor of Tianjin Yishi Bao, was wanted for criticizing current affairs, so he left. Duan Sheng succeeded as the lead writer, and published 170 comments in a few months, criticizing the disadvantages of the times, being bitter and bitter, and the key points in the hole. Finally, he was forced to leave his post and teach at Nanjing Central University again because he wrote an editorial entitled "On the General Trend of North China-Sending Chairman Huang Fu to the South". Liu Yazi wrote the poem "Huai Ren", praising "Qian Lang's talent is quite vertical and horizontal, and he can talk about politics and military affairs. Take the bridle to clarify that I am tired, and you can support the forum with one arm." After the outbreak of War of Resistance against Japan, he was hired by Peking University to withdraw to Kunming with the school to participate in the preparation of The National SouthWest Associated University Law School. In addition to teaching hard, he wrote papers on international current affairs and monographs on academic research, and actively participated in activities to strengthen the anti-Japanese United front. From 1937 to 1949, he was invited to attend academic conferences and lectures in the United States four times. At the end of 1947, he served as a visiting professor at Harvard University and gave a lecture on Chinese Government and Politics (1950, English version of Harvard University Press, USA). He resigned from the appointment of a famous American university and returned to Peking University in 1948. On the eve of the liberation of Peiping, he kept close contact with the underground party of the Chinese Communist Party, protected revolutionary students and maintained school order until the People's Liberation Army took over. After the founding of the People's Republic of China, he successively served as the dean of Peking University Law School, the dean of Beijing University of Political Science and Law, the vice president of the Institute of Foreign Affairs, the vice president of the Association for Friendship with Foreign Countries, the director of the World Peace Council, and the consultant of the Ministry of Foreign Affairs, and devoted himself to the legal system construction of New China. In 1954, he was hired as a consultant to the Constitution Drafting Committee of the National People's Congress and participated in the drafting of the first constitution of New China. In 1957, Duansheng was misclassified as a rightist and forced to leave the pulpit. In 1974, under the personal intervention of Premier Zhou Enlai of the State Council, he became a consultant and legal adviser of the Institute of International Studies of the Ministry of Foreign Affairs. After the end of the "Cultural Revolution", he was old and still enthusiastically devoted himself to state government affairs. He was elected as a member of the Standing Committee of the Sixth National People's Congress, deputy director of the Law Committee, etc., and edited a series of legal books. In 1981, he should be appointed as a professor at Foreign Affairs University. In the same year, he joined the Communist Party. Died of illness on January 21, 1990. All the faculty, staff and alumni of China University of Political Science and Law have a long-term alliance: "I have been teaching for sixty years, I have been tireless in teaching others, devoted myself to cultivating talents, and my teachers are like the sea. I have been in politics for most of my life, sharing thick and thin, treating each other with sincerity, doing everything for the people, looking like a mountain, and mourning for the public from all over the world." In addition to short stories, Duan Sheng's works include Comparative Constitution co-authored with Wang Shijie, Reactionary Nature of Bourgeois Constitution co-authored with others, and History of Political System of the Republic of China. He is the only author of Chinese Government and Politics (English version), Transformation of the Postwar World, and Politics and Political Science. He has translated British History, French Government, German Government and French Political Organization. Duan Sheng has been engaged in political science and legal research all his life, and as a scholar, he actively intervened in politics and society, and put forward his own views on a series of major issues. The consular jurisdiction of the concession proposed in 1925 runs counter to the theory of "sovereign territory" based on public international law. The consular jurisdiction of the foreign powers in China is not voluntary as given to the Muslim countries in the Near East in the past, but purely imposed by the powers after the opium war. The "law" of "trial according to law" stipulated in the concession treaty is "procedural law" rather than "substantive law", and the consular judgment "oversteps the permission of the treaty", so it should be abolished, and it is advisable to abolish the method of "courtesy before soldiers" (Extraterritorial Issue). On "September 1st. Sino-Japanese relations after the 8th Incident, in 1934, Huang Fu negotiated with the Japanese government on behalf of the Chinese government, and put forward that" the Sino-Japanese issue cannot be solved at all ", which was unfavorable to our country (On the General Trend of North China-Sending Chairman Huang Fu to the South). Regarding the constitutional movement, it is put forward that "there are no certain procedures for administration, and the people are often oppressed. No matter how the political system stipulates, politics will never be so clever, which makes it easy for the law to accommodate the facts and difficult for the facts to follow the law", and "if there is a law that cannot be implemented and is not observed by others, it is better to be farther away from the rule of law than impossible" (Comment on the Constitutional Movement and Charter Amendment, 1929). At the beginning of liberation, it was put forward that "if private industry and commerce are over-rewarded for industrialization, there is a danger of becoming capitalism. Over-emphasis on state-owned undertakings will inevitably be in danger of delaying production because of the weak financial resources of the state" (United Front, People's Government, Common Program, 1950). Died in Beijing on January 21, 1990.
