Лю Бан
Liu Fei (), formally King Daohui of Qi (; died 189 BC) was the eldest son of Liu Bang, Emperor Gaozu of Han, and Consort Cao—initially his mistress. After Liu Bang decisively defeated Xiang Yu in the Battle of Gaixia in 202 BC, he proclaimed himself the emperor of the new Han dynasty and named Liu Fei, his first son, the King of Qi.
