Blood on Wolf Mountain, also known as The Wolf Hill, Bloodbath in Langshan, and Bloodshed on Wolf Mountain, is a Chinese film directed by acclaimed Shanghainese film director Fei Mu. Made just prior to the commencement of full-scale war with Imperial Japan, the film itself is often considered an allegory of conflict between China and Japan that had been going on intermittently since the Invasion of Manchuria in 1931. The film was produced by the Lianhua Film Company and was released in November of 1936.
