Uar and Hephthalites
According to the Book of Liang, the Yanda (Hephthalites) were an offshoot of the Yuezhi. It mentions an envoy sent in 516 by their Yandaiyilituo/Hephthalite king to the court at Nanjing. Chinese chronicles define Yanda as the name of a clan leading the Uar. In the Book of Wei they are supposed to be a variety of the Yuezhi, while the Uar, who are also described, are possibly an offshoot of the Tiele. The Book of Wei indicates, however, that the Yanda do not share a similar language with the (Tungusic) Rouran or (Turkic) Tiele. It is said that the Yanda language can be easily translated by the Tuyuhun, a group of peoples from the Koko Nor.
Kazuo Enoki believed the Yanda to be an Iranian Satem-language like the Hazara, in which case they can't be related to the Indo-European Kentum-branch of Tocharians.
