Watch soap2day. Filmed around March 1938, under the auspices of the China Wartime Film Research Association, but not publicly screened until 1941. Photographs of the Long March are very rare, as are those of its endpoint in Yan'An, the communist base of Northwest China in Shanxi province. Mao ZeDong may be seen along with other Chinese Communist leaders, including Liu Shao Qi, Ding Ling, Luo Rui Jing, and Kang Sheng.
