Gao Gang
During its early years, the CCDI was not a powerful institution. Although it focused on abuses by party veterans and senior officials, the CCDI rarely appeared on record at that time as investigating (or solving) those problems. The few mentions of CCDI inspectors in the press highlighted their failures. Despite the support of Mao Zedong and the central party leadership, it was often unable to fulfill its mandate in the provinces. According to a "People's Daily" editorial, party inspectors "gave up the struggle and proved themselves unable to persist in ... upholding the dignity of Party discipline when they encountered great obstacles." Aware of Yan'an Rectification Movement successes and CCDI failures, the party leadership used mass mobilisation and ideological campaigns to tackle party corruption during the 1950s. In the wake of the Gao Gang–Rao Shushi affair, the CCDI was replaced by the CCC.
