1September, 927, Chiang Kai-shek Group and Wang Ching-wei Group in the Kuomintang carried out counter-revolutionary confluence on the grounds of anti-communism, which became the "confluence of Ning and Han".
After Chiang Kai-shek and Wang Ching-wei betrayed the revolution one after another, the Kuomintang in China has become a political party controlled by reactionary groups representing the interests of landlords and comprador bourgeoisie. 1After July 1927, there were three factions in the Kuomintang: Nanjing, Han and Shanghai. In Nanjing, there were the "National Government" and the "Central Party Department" controlled by Chiang Kai-shek. In Wuhan, there are "National Government" and "Central Party Department" controlled by Wang Jingwei; In Shanghai, Xishan Conference School also carries out activities in the name of "Central Party Department". In addition, there are local forces such as Guangdong, Guangxi and Shanxi. Both Nanjing and Han concentrated the most important leaders of the Kuomintang, each holding the government, the army and a large territory, becoming the most powerful forces. They competed for the highest power, but soon began to merge on the basis of anti-communism.
