Story:
During the Chu-Han Contention period, Xiang Yu was concerned that a prolonged standoff would be disadvantageous to him. He then captured Liu Bang's father and threatened that if Liu Bang did not surrender, he would kill his father, cook him into a broth, and eat him.
Upon hearing this, Liu Bang replied, 'We are sworn brothers, so my father is also your father. If you do kill him and make broth, please share a cup with me.'
Xiang Yu, persuaded by Xiang Bo, ultimately did not carry out his threat.
