On this day 114 years ago, on June 11, 1911 (May 15, 1911 in the lunar calendar), Chen Duxiu was arrested for distributing the "Beijing Citizens' Manifesto". Chen Duxiu and Li Dazhao drafted the "Beijing Citizens' Manifesto", which was translated by Hu Shi in English. On June 1, 1911, Chen Duxiu, Li Dazhao and others personally went to Beijing Chengnan Amusement Park and "New World" to distribute the "Beijing Citizens' Manifesto" to the masses. The manifesto said: "The Chinese nation is a nation that loves peace. Although today is suffering from intolerable oppression at home and abroad, this is still the purpose of putting forward the minimum requirements for the government, such as the left: (1) Diplomacy with Japan, not abandoning the economic rights of Shandong Province, and canceling the four-year and seven-year secret treaties of the Republic of China; (2) Expulsion of Xu Shuzheng, Cao Rulin, Lu Zongyu, Zhang Zongxiang, Duan Zhigui, and Wang Huaiqing from Beijing. (3) Abolition of the two organs of the infantry commander and the police commander. (4) The Beijing security force should be organized by citizens. (5) Citizens must have the absolute right to freedom of assembly and speech. The declaration concluded: "Our citizens still hope to achieve this goal by peaceful means. If the government does not want peace and does not fully obey the hopes of the citizens, we, the students, businessmen, laborers, soldiers, etc., can only take direct action to achieve fundamental transformation. I hereby declare that I beg for the understanding of scholars and women at home and abroad. "On the same day, Chen Duxiu was arrested by undercover detectives. On the 8th, Chen once wrote an article in the" Weekly Review ":" There are two birthplaces of world civilization: - the scientific research laboratory, - the prison. We young people must decide to go to prison when we leave the research laboratory, and enter the research laboratory when we leave the prison. This is the most noble and beautiful life in life. "
