《汉书·传·谷永杜邺传》
谷永听说了这件事，写给王谭一封信说：您自身具有周公、召公的品德，持有管子、晏子的操行，敬重有才德的人并能谦恭地对待他们，喜欢做善事不知疲倦，早就应该位在大将军了，因为有大将军在，所以抑郁在家，不能舒展忧愤。
永闻之，与谭书曰： 君侯躬周、召之德，执管、晏之操，敬贤下士，乐善不倦，宜在上将久矣，以大将军在，故抑郁于家，不得舒愤。
When Gu Yong heard of this matter, he wrote a letter to Wang Tan, saying: You yourself are of the same virtue as Duke Zhou and Duke Shao, you hold the conduct of Guan Zhong and Yan Ying, you respect those of ability and virtue and treat them with humility, you love doing good and never tire, you should have been a top military general long ago. Since the top military general was still in the position, you were depressed at home, unable to release your worries and resentment.
