Narrator: Tian Ruiguo

On March 12, 1925, after Sun Yat sen died of illness in Beijing, the contradiction between the Kuomintang and the Communist Party was growing.

　　……

In 1926, Chiang Kai shek ordered his men to send an order to the residence of Li Zhilong, Acting Director of the Navy Bureau of the Guangzhou National Government and a Communist Party member, to transfer the Zhongshan Ship out of Guangzhou and go to Huangpu. However, Chiang Kai shek changed the time for the Zhongshan Ship to sail back and forth, and then spread rumors and pinned the hat of conspiracy on the Communists.

On March 20, Chiang Kai shek imposed emergency martial law in Guangzhou, arrested Li Zhilong, monitored and placed a large number of Communists under house arrest, disarmed the workers' pickets of the provincial and port strike committees, surrounded the Soviet consulate, and monitored Soviet advisers.

Mao Zedong and others analyzed the situation at that time and advocated a firm fight back against Chiang Kai shek, but the representatives of the Communist International advocated concessions. Under the guidance of the compromise policy, the CPC Central Committee accepted Chiang Kai shek's unreasonable demands, and the Communists were forced to withdraw from the First Army.
