《史记·十二本纪·项羽本纪》
他自我夸耀功勋，逞一己私智，不效法古人，以为创立霸王的事业，需要用武力来经营天下，仅五年时间就丢了他自己的国家，身死东城，还没有觉悟，不自我谴责，这就不对了。
自矜功伐，奋其私智而不师古，谓霸王之业，欲以力征经营天下，五年卒亡其国，身死东城，尚不觉寤而不自责，过矣。
<number>. He had self-praise, used his own narrow wisdom, and did not learn from the ancients. He thought that he had established the Hegemon King legacy and had to use force to run the empire, but in only five years he lost his own country, was killed in Dongcheng, and still did not understand or blame himself – this was wrong.
