Liu Biao
Kuai Yue (died 214), courtesy name Yidu, was an adviser to the warlord Liu Biao during the late Eastern Han dynasty of China. He was the younger brother of Kuai Liang. When Liu Biao died and Liu Cong succeeded him, Kuai Yue recommended that he surrender to Cao Cao. Cao Cao later praised Kuai Yue, saying, "I would rather obtain Kuai Yue than Jing Province."
