叶群
While in Moscow, Lin became infatuated with Zhou Enlai's adopted daughter, Sun Weishi, who was studying in Moscow from 1938 to 1946. Before returning to China, in 1942, Lin proposed to Sun and promised to divorce his wife, from whom Lin had become estranged. Sun was not able to accept Lin's proposal, but promised to consider marrying Lin after completing her studies. Lin divorced Liu Ximin after returning to China, and married another woman, Ye Qun, in 1943. The relationship between Sun and Ye was notably bad. After returning to Yan'an, Lin was involved in troop training and indoctrination assignments.
