① Several points that should be involved: indecision (changing the decision to attack Liu Bang, not expressing his position on Fan Zeng's attempt to assassinate Liu Bang during the dinner, repeatedly escaping from the banquet and being safely accepted); Frank and straightforward (heard Liu Bang's "thank you" and named the informant, heard Fan Kuai's "slander" and "failure to respond"); Poor use of people (not listening to Fan Zeng at a critical moment); Arrogance (the number of seats at a party).

(2) The key is his "pretentiousness" (I heard that Liu Bang's "desire for Wang Guanzhong" violated his dignity and decided to attack; However, after learning that Liu Bang's "official library" was waiting for him to deal with it, he gave up the attack plan. He didn't regard Liu Bang as his main rival, thought it was useless to kill him, and Liu Bang paid attention to safeguarding his dignity, which made him "unbearable". )

(3) It is the essence of Xiang Yu's tragic image to pretend to be meritorious and finally fail. It is from this point that we say that although the dispute over the Hongmen Banquet is the beginning of the dispute between Liu and Xiang, it has already heralded the end of this struggle.

2. About the image of Liu Bang.

(1) Liu bangqin went to Hong Men to apologize, which was a bold decision, otherwise it would not be enough to stop Xiang Yu's attack; "Join the army at once and kill Cao"-all these can be regarded as resolute and decisive. (2) Liu Bang, who "first broke the Qin Dynasty and entered Xianyang", was an accomplished man. But in front of Xiang Yu, he is humble and polite, afraid of an accident, even "but before he could conquer, he was dead", which also feels disrespectful, which shows his flexible personality.

(3) When I first met Xiang Bo, that is, "being my brother", "giving birthday gifts" and "making an appointment", it can be seen that he is good at wooing people and using them for his own use.

3. Other roles.

Characters in Liu Bang Group: ① Sean-resourceful (Xiang Bo was transferred by him, Fan Kuai was transferred by him, and the matter of "leaving thanks" was also handled properly. (2) Fan Kuai-particularly brave and crude (the action of breaking the account; Glow without saying a word after entering the account; Take the opportunity to face Wang Xiang; Advocating to leave without saying goodbye).

Characters in Xiang Yu Group: ① Fan Zeng-visionary and headstrong (asserting that Liu Bang is ambitious); Lv Xiangzhuang killed Liu Bang; Broken jade bucket; Asserting that "whoever catches the king of the world will be punished repeatedly." (2) Xiang Bo values friendship and is easily confused by false friendship. (3) Chen Ping-at that time, he had a heart for Liu Bangyou (when calling for release).
