後蜀
In 939, the non-Han chieftain Peng Shichou (彭士愁), who was formally a Later Shu vassal (as the prefect of Xi Prefecture (溪州, in modern Xiangxi Tujia and Miao Autonomous Prefecture, Hunan), attacked two prefectures belonging to Later Shu's southeastern neighbor Chu (which was formally a Later Jin vassal) — Chen (辰州, in modern Huaihua, Hunan) and Li (澧州, in modern Changde, Hunan) — and sought aid from the Later Shu imperial government to further advance. Meng refused, finding that the campaign was too far away from Later Shu proper. Forces sent by Chu's prince Ma Xifan subsequently defeated Peng, who surrendered to Chu. His territory became Chu territory.
