Xiahou Ba
Xiahou Wei was the fourth son of Xiahou Yuan, a general who served under Cao Cao, the warlord who laid the foundation for the Cao Wei state in the late Eastern Han dynasty before the Three Kingdoms period. His mother, whose maiden family name was Ding (丁), was a younger sister of Cao Cao's first wife. Xiahou Wei was close friends with Cao Cao's sons, including Cao Pi and Cao Zhi. He also knew Yang Hu since young and felt that he was an extraordinary talent, so he advised his second brother Xiahou Ba to arrange a marriage between Yang Hu and Xiahou Ba's daughter. Yang Hu later became a famous general in the late Three Kingdoms period and the Jin dynasty (266–420).
