《汉书·传·傅常郑甘陈段传》
谷吉上书说道： 中国和夷狄有笼络而不断绝之义，现在既然已抚养成全他的孩子十年，恩泽已很厚了，如今他到空旷绝远之地而不去护送，到了边塞就返回，这是表示抛弃他不再爱护，使他们失去归附的心意。抛弃以前的恩泽，产生后来的怨恨，不妥。
吉上书言： 中国与夷狄有羁縻不绝之义，今既养全其子十年，德泽甚厚，空绝而不送，近从塞还，示弃捐不畜，使无乡从之心，弃前恩，立后怨，不便。
Gu Ji remonstrated in his memorial: China and the barbarian peoples have a tradition of appeasement and conciliation but do not break ties completely. Now that we have cared for and raised his child for ten years, our kindness is already great. If we refuse to escort him to a vast and remote land and only return to the frontier, this will show that we will abandon him and no longer care for him and make him lose his intention to submit. Casting off earlier kindnesses will give rise to later resentments, which is improper.
