Cheng Bugao
Cheng Bugao was a prominent Chinese film director during the 1930s. Employed by the Mingxing Film Company, Cheng was responsible for several important "leftist" films in the period, including the Wild Torrents and Spring Silkworms. Both films were based on screenplays by Xia Yan.
After the Second Sino-Japanese War, Cheng moved to Hong Kong, where he made films of a purposefully apolitical nature.
