陈希同
Over the next decade, he acquired a reputation as Jiang's 'hatchet man' against rivals. In 1992 he supposedly helped Jiang remove President Yang Shangkun and elder PLA General Yang Baibing, who threatened Jiang's support within the military. Then, he used an anti-corruption campaign to orchestrate the downfall of Beijing party chief and Jiang's foe Chen Xitong. Because he was seen to represent highly partisan interests, many of Jiang's factional opponents were said to be highly resistant to Zeng joining the Politburo as a full member for years. However, Jiang made it clear that a 'pre-condition' for his stepping down at the 16th Party Congress was for Zeng to become a member of the elite Politburo Standing Committee.
