Zhang Chunqiao
Spurred by the events in Beijing, 'power seizure' ("duoquan") groups formed all over the country and began expanding into factories and the countryside. In Shanghai, a young factory worker named Wang Hongwen organized a far-reaching revolutionary coalition, one that galvanized and displaced existing Red Guard groups. On January 3, 1967, with support from CRG heavyweights Zhang Chunqiao and Yao Wenyuan, the group of firebrand activists overthrew the Shanghai municipal government under Chen Pixian in what became known as the "January Storm," and formed in its place the Shanghai People's Commune.
