《史记·十二本纪·高祖本纪》
汉王历数项羽的罪过说： 最初我和你项羽都受命于怀王，说是先入关平定关中的，就在关中做王。你项羽违背约定，让我在蜀、汉做王，这是第一罪。
汉王数项羽曰： 始与项羽俱受命怀王，曰先入定关中者王之，项羽负约，王我於蜀汉，罪一。
King Han enumerated Xiang Yu's crimes and said: At first, you Xiang Yu and I were both ordered by King Huai to enter the pass and pacify Guanzhong first, and then became king in Guanzhong. You Xiang Yu violated the agreement and let me be the king in Shu and Han. This is the first crime.
