张春桥
Two members of the CRG played a significant part in the affair over the Shanghai Commune. Due to his connections with the city (he had been secretary of the Shanghai Party Committee until July 1966), Zhang Chunqiao was dispatched from the centre in November 1966 to mediate the crisis over the siege of some worker's groups at Anting. Early in January the next year, Zhang Chunqiao was to return again to Shanghai with his CRG colleague Yao Wenyuan to lead the new order established after the fall of the old Party apparatus, and in early February he was to become head of the newly formed Shanghai Commune. However, the combination of questions over the legitimacy of the Commune's leadership, and a change in attitudes to communes in general at the centre, meant that the Shanghai Commune was to last less than a month.
