On this day, 88 years ago, on June 1, 1937 (April 23, 1937, the lunar calendar), Zhou Enlai and Chiang Kai-shek negotiated in Lushan. Representatives of the Communist Party of China Zhou Enlai, Qin Bangxian, and Lin Boqu and representatives of the Kuomintang Chiang Kai-shek, Shao Lizi, and Zhang Chong negotiated on the issue of bipartisan cooperation in resisting Japan in Lushan. In early June 1937, Zhou Enlai went to Lushan to hold talks with Chiang Kai-shek with the program for cooperation between the Kuomintang and the Communist Party of China for resisting Japan between the two parties. Song Ziwen, Song Meiling, Zhang Chong and others negotiated back and forth. Chiang Kai-shek went back on his word and ignored the cooperation program drafted by the Communist Party and directly raised the issue of the form of cooperation between the two parties: the National Revolutionary League was established, composed of an equal number of cadres elected by both the Kuomintang and the Communist Party, with Chiang serving as chairman and having the final say; the Red Army could be organized into 3 divisions and 12 regiments, with 45,000 people. The Communist Party appointed division commanders and deputy officers appointed by the Kuomintang; no general headquarters could be set up above 3 divisions, and political training offices could be set up above the division. Mao Zedong and Zhu De left the Red Army and went abroad to study abroad; The Shaanxi-Gansu-Ningxia Border Region government is appointed by the central government as chief officials, and so on. In this regard, Zhou Enlai said that the organizational principles of the National Revolutionary League must be decided after consultation, and no other matters could be agreed. On the 16th, representatives of the Communist Party of China returned to Yan 'an. On June 25, the Secretariat of the Central Committee of the Communist Party of China proposed a new proposal for negotiations with the Kuomintang. The new proposal makes concessions on some important issues. Regarding the organizational form of cooperation between the two parties, they agreed in principle to form the National Revolutionary League and recognized that Chiang Kai-shek had the final say in accordance with the Common Program. The propositions on some specific issues were: if Chiang Kai-shek agreed to establish a general military headquarters, the Red Army would reorganize after its name was announced; democratic elections were held in the Shaanxi-Gansu-Ningxia Border Region in July, and three people, Zhang Ji, Song Ziwen and Yu Youren, were recommended to Chiang, and one of them was selected to serve as the chief executive of the Border Region and Lin Boqu was appointed as the deputy chief executive; Mao Zedong would not refuse to go out to work, but he would not do so at the right time; and he would not abandon the basic principles of democratic election by the National Assembly. On the 28th, Zhou Enlai telegraphed Chiang Kai-shek, stating that the Central Committee of the Communist Party of China believed that if the three divisions after the reorganization of the Red Army had no command organs above them, it would be impossible to reorganize and Zhu De could not leave. On the 29th, the Central Committee of the Communist Party of China received a telegram from Nanjing: After the reorganization of the Red Army, only a Political Training Office could be set up. The Central Committee of the Communist Party of China decided that troops can be commanded in the name of a political organ, but they must have the organization and functions equivalent to the command organ. If Zhu De cannot be elected director of a political organization, he will adapt himself.
