Hongmen banquet is puzzling. Somebody help me. .

1 Xiang Yu is a nobleman and Liu Bang is a rogue. Xiang Yu really looked down on Liu Bang and thought that Liu Bang was no threat. Xiang Yu, who pretends to be lofty, may think that killing Liu Bang will get his hands dirty. And killing your allies for no reason is also a concern of the overlord. According to historical records, Xiang Yu's characters have their own characteristics. Secondly, he was cheated by Sean. Fan Ceng, the father of Asia, said that there is a chess game called lose-lose! He deliberately left a trick for Xiang Yu. In fact, even if Yapu got the trick, he would have reached Liu Bang's hand, so the trick was his deviance, deliberately saying that Sean, Xiao He and others colluded with him to plot! As for Liu Bang killing all the founding heroes, it is the same in any dynasty. It's called: "Birds hide their bows, rabbits die and dogs cook"! How can a general enjoy peace only when he goes to war? ! ! Chu Huaiwang was the leader of various anti-King movements. The descendants of Chu lived in Gaozhen, and Liu Bang was afraid that they would turn against each other.
