In
January 1967 during the "
power seizure phase" of the Cultural Revolution in Zhejiang, the officially sanctioned
Maoist rebel organization, the (, subsequently United Headquarters) organized a rally to humiliate and attack
Jiang Hua, then the first secretary of the
Communist Party Zhejiang Provincial Committee. But another rebel organization, the () broke up its rally, allegedly backed by provincial party elites, allowing Jiang to fly to safety in Beijing. This started a row between the two rebel groups, which lasted during the next few years during the Cultural Revolution in Zhejiang. Many armed struggles and political struggle occurred throughout major cities in the province. In 1969, when the tide of "leftism" subsided, both organizations formally disbanded, but the core members retained some sort of underground organization. In early 1974, the
Anti-Lin Anti-Confucius campaign took place, and some activists associated with the old United Headquarters seized opportunity to resume activism to try to take power from the local party elites. The most notable rebel leaders on the United Headquarters side were Zhang Yongsheng, Weng Senhe, and He Xianchun. The rebel leaders controlled the Trade Union Council, which in turn mobilized workers into urban militia who substituted the military and public security forces in keeping social order. The rebel leaders used these urban militia to carry out raids and intimidation against their political opponents. Combined with their allies in the party bureaucracy, they paralyzed the local administration. Many workers feared the violence at their workplaces and this paralyzed production. In late 1974, both
Wang Hongwen and
Deng Xiaoping made trips to Hangzhou to try to quell the factional fighting. == Incident ==
