On this day, 94 years ago, on December 15, 1931 (November 7, 1931, the lunar calendar), Chiang Kai-shek went out for the second time. On December 15, 1931, Chiang Kai-shek sent off the field for the second time. After the Fourth National Congress of the Kuomintang was held in Nanjing, Guangzhou and Shanghai respectively, the Central Committee of the Kuomintang in Nanjing sent a telegram inviting members of the Central Committee of the Guangdong and Shanghai sides to Nanjing to hold the First Plenary Session of the Fourth National Congress of the Kuomintang. However, the Guangdong side insisted that Chiang Kai-shek must step down, otherwise he would not go to Nanjing to attend the meeting. Instead, he requested that the First Plenary Session of the Fourth National Congress be held in Shanghai. Due to pressure from Guangdong, Chiang Kai-shek telegraphed a telegram that day to resign from various positions as chairman of the National Government. On the same day, the Central Executive Committee of the Nanjing Kuomintang Party held a meeting and decided to approve Chiang Kai-shek's resignation application, with Lin Sen acting as chairman of the National Government and Chen Mingshu acting as president of the Executive Yuan. On the day when the power was sent down, Chiang Kai-shek convened a state conference and planted cronies in key central and local departments to control central institutions to prepare for the future.
