Within a period of 10 days in August 2015, former Chinese regime leader Jiang Zemin’s inscriptions were removed from two different locations: the Shanghai Air Force Political Academy on August 13 and the Chinese Communist Party Central Party School on August 21. The Chinese Communist Party has a tradition of removing sacked officials’ inscriptions. For example, inscriptions by Guo Boxiong, Xu Caihou, and Zhou Yongkang were all removed after they were arrested. Guo, Xu, and Zhou were all members of Jiang’s faction.
Many people viewed the removal of Jiang’s inscriptions as an indication of the elimination of Jiang’s influence and an omen of his impending political demise. Some others thought it was just a normal engineering operation, since Jiang was fond of leaving inscriptions and writing poems as he traveled with his entourage around the country. They thought it was normal to make some changes.
