Liu Wenhui was one of the powerful military figures of the Liu clan that dominated Sichuan from the 1920s. He was defeated by his nephew, Liu Xiang, in the last internal power struggle of the warlord era in Sichuan and retreated to the frontier of Ya'an in 1933, where he and his 24th Army were nominally allied to the Guomindang under Jiang Jieshi. In Ya'an, Liu Wenhui was charged with developing the new "Xikang Province", which was formally established in 1939. The official positive interpretation of Liu Wenhui's rule is that he was a patron of modern education; he is better known locally for his power politics and domination of the opium trade. Liu Wenhui's cooperation was critical in the "peaceful liberation" of Ya'an, and he was rewarded with a post in the central government's Bureau of Forestry as a reward.
