Zhang Chunqiao
After the Communist takeover in 1949, some of the offices were used by the Municipal Finance Committee. In 1952, the building was taken over by the Municipal Government. In 1956, it once again became a hotel under the name "Peace Hotel". During the Cultural Revolution, the hotel was used by the Gang of Four, most famously by Zhang Chunqiao as he headed the Shanghai Commune from headquarters in the Peace Hotel.
