Allusions come from the hongmen banquet. Fan Zeng, the counselor of Xiang Yu, disapproved of the cooperation between Xiang Yu and Liu Bang, so he instructed Xiang Zhuang to pretend to dance a sword at the Hongmen banquet and take the opportunity to kill Liu Bang. At the Hongmen Banquet, Xiang Bo, who originally belonged to Xiang Yu, benefited from Liu Bang's counselor Sean, so he pretended to dance the sword and took the opportunity to shelter Liu Bang everywhere. Until Sean sent Fan Kuai to the hongmen banquet, liu bang's danger was relieved.
This poem is to persuade Xiang Zhuang in the tone of a third party.
