Ninety years ago today, on January 15, 1935 (December 11, 1934 in the lunar calendar), the Zunyi Conference was held. Zunyi has been an important town in northern Guizhou since ancient times. In January 1935, the Chinese Red Army of workers and peasants liberated the city during the Long March. On January 15, the enlarged meeting of the Political Bureau of the Party Central Committee, the Zunyi Conference, was held in the mansion of Bai Huizhang, the former Guizhou warlord division commander, at No. 87 on the east side of Pipa Bridge (later renamed Ziyin Road and Hongqi Road) in Zunyi City. After the Red Army entered Guizhou and captured Zunyi City, it has always been the headquarters of the Central Military Commission and the General Command of the Red Army. Attending the Zunyi meeting were Politburo members and alternates Mao Zedong, Zhou Enlai, Zhu De, Chen Yun, Zhang Wentian (Luo Fu), Qin Bangxian (Bo Gu), Liu Shaoqi, Wang Jiaxiang, Deng Fa, He Kequan (Kai Feng), Central Secretary-General Deng Xiaoping, Red Army headquarters and corps heads Liu Bocheng, Li Fuchun, Nie Rongzhen, Peng Dehuai, Yang Shangkun, Li Zhuoran, Lin Biao, military adviser sent by the Communist International, and translator Wu Xiuquan. The main topic of the meeting was to summarize the experience and lessons since the fifth anti-" encirclement and suppression ". First, Bo Gu made a summary report on opposing the enemy's fifth" encirclement and suppression ". His report lacked due understanding of the failure of this anti-" encirclement and suppression" war and justified its mistakes. Next, Zhou Enlai delivered a military work report on behalf of the Military Commission. In the report, he objectively summarized and analyzed the overall situation since the Fifth Anti-" Encirclement and Suppression "War, criticized Bogu and Li De's serious mistakes in their strategic and tactical guidance that were divorced from the actual situation of China's revolutionary war, and made sincere self-criticism. He believed that the Red Army was facing a more serious enemy situation than during the Fifth Anti-" Encirclement and Suppression" War. Only by changing the wrong military leadership and letting Mao Zedong, who was good at using mobile warfare, command the Red Army, could the Red Army have hope and the revolution can succeed. Zhou Enlai's speech made the participating comrades see the bright prospect that the Red Army will be saved and will surely win. At the meeting, Zhang Wentian gave a report criticizing the "left" military line, criticizing a series of serious mistakes made by Bogu and Li De on military issues. As a member of the Political Bureau of the Central Committee and secretary of the Secretariat at that time, he was able to separate from the "left" line and played an important role in correcting the mistakes of the military leadership at the meeting. Mao Zedong made an important long speech at the meeting, focusing on criticizing a series of fundamental mistakes made by the "left" adventurism in military leadership; and using the fact that he opposed the enemy's first four "encirclement and suppression", he rationally refuted Bogu's wrong point of view in the summary report defending the failure of the fifth anti-" encirclement and suppression ". The vast majority of the comrades attending the meeting clearly expressed their support for Mao Zedong's correct proposition and criticized Li De and Bogu's mistakes in military command. The enlarged meeting of the Politburo reorganized the Central Secretariat and the Central Revolutionary Military Commission in accordance with the opinions and demands of the vast majority of comrades. Mao Zedong was elected as a member of the Politburo Standing Committee, and Bogu and Li De were abolished from the highest military command. Zhang Wentian was elected to replace Bogu in the general responsibility of the Central Committee, and Mao Zedong and Zhou Enlai were in charge of the military. Subsequently, a three-person military command group was established headed by Mao Zedong, with Zhou Enlai and Wang Jiaxiang participating. From then on, Wang Ming's "left" adventurist rule in the Party Central Committee ended, and Mao Zedong's leadership position in the Red Army and the Party Central The Zunyi Conference was the first meeting of the Communist Party of China to independently apply the basic principles of Marxism-Leninism to solve problems in its own line, principles and policies, so that the Red Army and the Party Central Committee could be preserved under extremely critical circumstances. From then on, the Red Army turned defeat into victory, turned the crisis into peace, and successfully completed the 25,000-mile Long March. Some participants of the Zunyi Conference started from the top left: Wang Jiaxiang, Zhu De, Chen Yun, Zhou Enlai, and from the bottom left: Bogu, Zhang Wentian, Liu Shaoqi, Deng Fa
