In order to completely, cleanly and completely annihilate the Kuomintang troops on the land of China, the Second Field Army led by Liu Bocheng and Deng Xiaoping accepted Chairman Mao Zedong's order to liberate the southwest. Photographers from the Central News Documentary Film Studio traveled with the troops and used film to record scenes of the People's Liberation Army soldiers' heroic fight to liberate the whole of China. In 1950, they produced the film "The Great Southwest Song".
