《史记·十二本纪·孝文本纪》
皇帝说： 当大臣诛灭吕氏子弟迎接我的时候，我犹豫不决，大家都阻拦我，只有中尉宋昌劝我，这样我才能够事奉宗庙。
上曰： 方大臣之诛诸吕迎朕，朕狐疑，皆止朕，唯中尉宋昌劝朕，朕以得保奉宗庙。
The emperor said: When the ministers killed the Lu clan children and welcomed me, I was hesitant, and everyone was blocking me, and only Zhongwei Song Chang encouraged me, so I was able to serve in the ancestral temple.
