This article reviews "the migration of the four Tiele tribes (Uighur 回鶻, Qibi 契〓, Sijie 思結, and Hun 渾)" in the Wuzutian era. It is conventional wisdom that these nomads moved into the Hexi 河西 region together at the same time. This "migration" theory has been speculated upon based on the writings of Xin-Tangshu, Jiu-Tangshu 『旧唐書』, and Tang-huiyao 『唐会要』. In the previous article, the author already pointed out that the Xin-Tangshu Uighur Account 回鶻伝 cannot be used as a basis for historical consideration, and it is necessary to eliminate the biased context that has been introduced by Xin-Tangshu editors. Based on such conclusion, the author maintains that the "migration" context in Xin-Tangshu was obviously borrowed by the editors from previous accounts and cannot be supported by extant historical sources. The conclusion of this article helps us to avoid considering all Turkic nomads living in the Hexi region as a single group and individually analyzes the ways in which each population group interacted with the Tang Dynasty.
