Liu Bocheng
The invasion of Japanese troops in 1937 marked the beginning of the Second Sino-Japanese War. During the invasion, Deng remained in the area controlled by the Communists in the north, where he assumed the role of deputy political director of the three divisions of the restructured Communist army. From September 1937 until January 1938, he lived in Buddhist monasteries and temples in the Wutai Mountains. In January 1938, he was appointed as Political Commissar of the 129th division of the Eighth Route Army commanded by Liu Bocheng, starting a long-lasting partnership with Liu.
