On this day, 98 years ago, April 1, 1927 (February 29, 1927, the lunar calendar), Chiang Kai-shek and Wang Jingwei secretly talked about anti-communist and "purging the party." On April 1, 1927, Chiang Kai-shek, Commander-in-Chief of the Northern Expedition Army in Shanghai, Wang Jingwei arrived in Shanghai. Chiang Kai-shek led Wu Zhihui, Li Shizeng, Li Zongren, Bai Chongxi, Bai Wenwei, Gu Yingfen and others to the Kong Xiangxi Mansion where Wang Jingwei stayed, and held secret talks with Wang on issues such as anti-communist and "party cleansing". Chiang Kai-shek asked Wang Jingwei to stay in Shanghai to lead the Kuomintang and sanction the Communist Party. Chiang Kai-shek said: "You mustn't go to Wuhan","You must always eliminate the Communist Party before talking." Chiang hoped to go to Nanjing with Wang to form a government and compete with the Wuhan government. On April 2, eight people including Wu Zhihui and Zhang Jingjiang convened a supervisory committee and filed a petition to "impeach" the Communist Party, saying that "the current National Government of China has more than enough to incite Borodin to dominate himself." Wang Jingwei said: "The Communist Party really regards its own party as a benefit." Soviet Russia just "uses our Kuomintang as a tool." He believes that the Kuomintang and the Communist Party "cannot continue to maintain peace." However, he did not agree to the immediate separation of the Communist Party. Second, he advocated convening a Kuomintang meeting to resolve the problem without using force. He repeatedly stated that the Prime Minister's policy of allowing the Communist Party to unite with Russia and workers and peasants cannot be changed at will, and solemnly stated: "I stand on the side of workers and peasants! Whoever harms workers and peasants is my enemy." Participants had a heated debate with Wang. Wu Zhihui was very excited and knelt down to Wang, begging him to change his attitude and stay in Shanghai to lead. Wang Ze quickly retreated, all the way up the stairs, and repeatedly said: "Young man, you are an old senior. I can't stand it like this, I can't stand it! "On the 3rd, Chiang and Wang reached the following agreement: (1) The Fourth Plenary Session of the Second Central Committee of the Kuomintang was held in Nanjing on April 15 to resolve the issue of" party disputes ". Before the Fourth Plenary Session, Wang Jingwei notified Chen Duxiu that Communist Party members in various places should temporarily suspend all activities and wait for resolution at the meeting;(2) Orders issued by the Central Committee of the Kuomintang Party and the National Government in Wuhan" if they believe that they are detrimental to the future of the party-state "may be refused;(3) The "most senior officials" of all party, government, and military agencies and groups have the power to ban and punish "conspirators and troublemakers"; (4)"All armed groups such as trade union pickets shall be under the command of the General Command", otherwise they will be regarded as a "conspiracy group" and banned. After Chiang and Wang reached an understanding, Chiang Kai-shek issued a telegram titled "Support Wang" declaring: "Chairman Wang is the most loyal comrade of the party and the most beloved teacher and friend of Chiang Kai-shek in ordinary times." He had "earnestly talked" with Wang about the "big plan of the party and state." After Wang's reinstatement,"all military and political, civil affairs, finance, and foreign affairs must be under the guidance of Chairman Wang." He asked all army commanders to "absolutely obey and sincerely support" Wang so that he could "exercise his powers completely freely."
