《新唐书·列传·卷一百四十》
颉利亡后，其下属有的投奔薛延陀，有的入西域，来降者有十多万。诏令商议如何安置他们。大家都说 ：突厥侵扰中国很久了，今天才丧国，他们并非慕义而自动来归附的，应该编入降俘籍，安置在兖、豫的空旷处，让他们学习耕田织布。百万突厥人，可化为庶民。这样中国增加了人口，而漠北就空而无患了。 
颉利之亡，其下或走薛延陀，或入西域，而来降者尚十余万，诏议所宜，咸言： 突厥扰中国久，今天丧之，非慕义自归，请悉籍降俘，内兗、豫闲处，使习耕织，百万之虏，可化为齐人，是中国有加户，而漠北遂空也。 
Afterwards the destruction of Jiali, some of his subordinates defected to Xue Yantuo, and some of them went to the western region, while more than 100,000 of them came to surrender. The imperial court issued an edict to discuss how to accommodate them. Everybody said: the Turks have been invading China for many years, only today did they lose their country. They did not come and submit automatically because of great righteousness, they should be categorized as prisoners of war, resettle them in the deserted lands of Yanzhou and Yuzhou. Let them learn farming and weaving, and the millions of Turks can become ordinary people. That way China can increase its population, and the northern part of the Mo Desert can become empty and we will be free from trouble.
