After a heavy defeat, Xiang Yu sent Wu She to persuade Han Xin, now King of Qi, to turn against Liu Bang and divide the realm three ways. Han Xin refused. “When I served Xiang Yu, my post was no more than a guard holding a halberd. My words were not heard and my plans were not used. So I left Chu and went over to Han.”
“The King of Han gave me the seal of supreme general and tens of thousands of men. He took off his clothes to dress me and pushed his food over to feed me. He listened to my words and used my plans. That is how I came this far. When a man trusts me so deeply, betraying him would bring bad fortune. I will not change, even in death.” (Records of the Grand Historian)
