If Xiang Yu hesitated at the banquet and didn't have the heart to kill Liu Bang, Fan Zeng's attitude was very firm. He wanted to kill Liu Bang. Then all he had to do was say to Xiang Zhuang: Go and carry out the previous orders, kill Liu Bang, and those who disobey them will be beheaded. At this moment, Xiang Zhuang walked into the banquet, raised his glass, drank with Liu Banggan, and then crashed with a clash. When Liu Bang was surprised, he drew his sword and killed him. Why do we have to dance swords? So much trouble?
So Xiang Zhuang doesn't have to dance with a sword, and dancing is useless. So is it unnecessary for Xiang Zhuang to dance sword at the banquet? In fact, everyone can see that Xiang Zhuang's so-called sword dance is a literary creation by Sima Qian to render the atmosphere of the banquet, which makes everyone feel that Xiang Yu is soft-hearted and wants Liu Bang to live.
Sima Qian just wanted to describe a banquet that was only fighting in the dark as a sword. It is very lucky to show Liu Bang in this way, and it is also a degradation of Liu Bang. From this, he expressed his hatred for the Han Dynasty and his helplessness and regret for Xiang Yu's failure. Therefore, Xiang Zhuang's sword dance is a polished and embellished literary work.
