100 years ago today, on January 11, 1925 (December 17, 1924, the Lunar Calendar), the Fourth National Congress of the Communist Party of China was held in Shanghai. On January 11,1925, the Fourth National Congress of the Communist Party of China was held in Shanghai. Twenty people including Chen Duxiu, Qu Qiubai, Cai Hesen, Cheng Lai, Li Lisan, Li Weihan, Xiang Jingyu, Deng Zhongxia, and Zhang Tailei attended the conference. Representative of the Communist International Vijingsky also attended the conference. The conference elected nine members, including Chen Duxiu, Li Da, Cai Hesen, and Zhang Guotao, as members of the Executive Committee of the CPC Central Committee, and five members, including Deng Pei, Wang Hebo, and Luo Zhanglong, were elected as alternate executive members. The Central Executive Committee elected Chen Duxiu, Zhang Guotao, Peng Shuzhi, Cai Hesen, and Qu Qiubai to form the Central Bureau, with Chen Duxiu as General Secretary. The conference passed 11 resolutions, including the "Resolution on the Report of Representatives Attending the Fifth Congress of the Communist International", the "Resolution on the Report of the Central Executive Committee", and the "Resolution on the Peasant Movement", and the "Second Amendment to the Articles of Association of the Communist Party of China" issued the "Declaration of the Fourth National Congress of the Communist Party of China". The conference documents pointed out that the Kuomintang is certainly an important tool in China's national movement, but it is not the entire movement. The Communist Party of China must adhere to a thorough democratic revolutionary program within and outside the Kuomintang, maintain its independence, and expand the leftist, oppose the rightist, and win over the center ideologically, organizationally, and mass propaganda. We must not only help the Kuomintang in practical struggles and organizational development, but also persist in fighting against their compromise. Regarding the issue of workers joining the Kuomintang, the congress stipulated different methods from the Ministry of Civil Affairs, and pointed out that it was necessary to fight against the influence of the bourgeoisie in the trade union movement and the separatist conspiracy of the Kuomintang rightists. On the 22nd, the Communist Party of China passed the "Resolution on Organizational Issues" at the Fourth National Congress. In order to attract revolutionaries among the broad masses of workers and peasants to join the Communist Party of China so as to facilitate the struggle between the party and the masses, the resolution stipulates that the original Party Constitution's stipulation that "more than five people can form a group" should be changed to "more than three people can form a branch"; the previous method of recruiting party members must be changed, and those who do have class consciousness can be directly recruited into the party. The resolution stipulates that party branches are the most basic organization of the party and should be established as units of industry and agencies. The work of the branch cannot be limited to educating and absorbing party members. It must also carry out agitation and propaganda work among the broad masses to improve the class consciousness of the broad masses. The party should also organize party and group organizations in the Kuomintang and other important political social groups to control the activities of the party and that group.
