夏侯覇
Years ago, Xiahou Ba's cousin was abducted by the Shu general Zhang Fei and became his wife. As a consequence, the Liu clan and Xiahou clan were linked together though Liu Shan's marriage with Empress Zhang (Zhang Fei's daughter). That was why Liu Shan called his son a nephew of the Xiahou family. Whether it was for political reasons or a private family issue, Liu Shan appointed the handicapped Xiahou Ba as General of Chariots and Cavalry in Shu.
