He tried to attack Qin Shihuang in Gubolangsha (southeast of Yuanyang, Henan Province) and fled to Xiapi (now Suining North, Jiangsu Province).

Later, Wang Cheng of South Korea was killed by Xiang Yu and returned to Liu Bang to become his important counselor. During the Chu-Han War, Liu Bang adopted the strategy of "long-term pacification of the world", put forward the strategy of not establishing the descendants of the six countries, uniting Ying Bu and Peng Yue, and reusing Han Xin, and advocated pursuing Xiang Yu and annihilating the Chu army. Houhou was founded in the Han Dynasty.
