The battle of Pengcheng, Liu Bang, was an obviously missed opportunity. If he and his 560,000 vassal allied forces arrived in Pengcheng, waiting for battle, Xiang Yu could not have succeeded in sneak attack with 30,000 elite soldiers. As long as Liu Bang and his 560,000 vassal allies stayed in Pengcheng for one month, Xiang Yu, who was fighting alone, had no choice but to surrender or commit suicide. However, Liu Bang arrived in Pengcheng, thinking that he had really succeeded. He drank and ate meat all day and was finally turned over by Xiang Yu. He can only escape to Guanzhong with his tail between his legs, regardless of his wife and children.
