Liu Bocheng
Zhou moved to the Jiangxi base area and shook up the propaganda-oriented approach to revolution by demanding that the armed forces under Communist control actually be used to expand the base, rather than just to control and defend it. In December 1931, Zhou replaced Mao Zedong as Secretary of the First Front Army with Xiang Ying, and made himself political commissar of the Red Army, in place of Mao. Liu Bocheng, Lin Biao and Peng Dehuai all criticized Mao's tactics at the October 1932 Ningdu Conference.
