In November 1966, at the outset of the Cultural Revolution, Zhang arrived in Shanghai representing the Central Cultural Revolution Group to stop Cao Diqiu's attempt to disperse workers in Anting. He signed the Five-point Petition of workers and then organized the Shanghai Commune along with Wang Hongwen and Yao Wenyuan in February 1967, essentially overthrowing the local government and party organization and becoming chairman of the city's Revolutionary Committee, which combined both the former posts of mayor and party secretary, until the latter post was restored in 1971. Zhang also initially served as one of the leaders of the Cultural Revolution Group, in charge of carrying out the Cultural Revolution around China. He spent much of the Cultural Revolution shuttling between Beijing and Shanghai.
