《汉书·传·匈奴传下》
所以自从汉朝建立，那些忠言直谏、计谋深远的大臣们，何尝不是费尽心机，出谋划策，在朝廷上争论如何对付夷狄？
故自汉兴，忠言嘉谋之臣曷尝不运筹策相与争于庙堂之上乎？
Therefore, since the founding of the Han Dynasty, those loyal and upright ministers who dared to speak out, and those ministers with far-reaching plans, how could they not have racked their brains and made suggestions, arguing in the imperial court about how to deal with the Yi Di?
