Chen Liangyu
He held a number of other academic positions through 1991, when Zhu appointed him as director of the Shanghai Municipal Planning Commission, allegedly because he had remarked that he hated central planning. That position led to a number of increasingly powerful positions within the municipal government of Shanghai, until he was appointed Mayor. However, Xu was demoted in 2001, to a far more obscure position as party chief of the Academy of Engineering in Beijing, apparently as the result of an internal party power struggles. Xu was replaced by Executive Vice-Mayor Chen Liangyu, one of Jiang's associates who was later convicted on charges of corruption.
