Seventy-eight years ago today, on March 7, 1947 (February 15, 1947), the second cooperation between the Kuomintang and the Communist Party broke down. Dong Biwu, a representative of the Communist Party of China, left Nanjing to express that the door to negotiations between the Kuomintang and the Communist Party of China had been completely closed. On March 7, 1947, 74 people, including Dong Biwu, Qian Zhiguang, Tong Xiaopeng, Wang Bingnan, Mei Yi, and other personnel from the Nanjing and Shanghai offices of the Communist Party of China and the Xinhua Daily, flew back to Yan'an by 4 US military planes. Zhu De and Zhou Enlai waited until they were greeted at the airport. Dong Biwu said in a book before his departure: Biwu and others were forced to leave here today, and they are indignant for no reason. The ties between the Kuomintang and the Communist Party that have never been broken for 10 years have now been cut off by the Kuomintang militants. We CCP The Kuomintang representatives Zhang Zhizhong and Shao Lizi, the NLD representative Luo Longji, and the US representative Colonel Ke Yi went to the airport to see the Chinese representative off.

The statement pointed out that "if Chiang Kai-shek does not change and give up this absurd step immediately, he will really have reached a dead end, and he should be responsible for all the consequences."
