Xiang Yu is jealous of the virtuous and talented, and those who have made meritorious deeds are harmed. Those who have made meritorious deeds are suspicious, and those who have overcome them are not rewarded, and those who have won the land are not rewarded. This is why they have lost the world. " However, Liu Bang said: "The public knows one, but the other is unknown. I am not as good as an ovary, because I am a winner thousands of miles away. Town country, comfort the people, give Wei, endless route for providing foodstuff, I am not as good as Han Xin. These three are outstanding people, and I can use them, so I take the world. Xiang Yu has a Fan Zeng and can't use it. This is why he is captured for me.
