叶群
Lin officially became China's second-in-charge in April 1969, following the 1st Plenary Session of the 9th Central Committee of the Communist Party of China. Lin's position as Mao's "closest comrade-in-arms and successor" was recognized when the Party constitution was formally revised to reflect Lin's future succession. At the 9th Central Committee, Lin's faction was unquestionably dominant within the Politburo. Of the Politburo's twenty-one full members, Lin counted on the support of six members: the generals Huang Yongsheng, Wu Faxian, Li Zuopeng, Qiu Huizo, Ye Qun; and Chen Boda, an ambitious ideologue. Lin's support surpassed the number of members aligned with Jiang Qing, and far surpassed those aligned with Zhou Enlai. Because over 45% of the Central Committee were members of the army, Lin's supporters dominated the Politburo, and Lin's power was second only to Mao's.
