The Chuban tribes, or "Weak Huns", took advantage of Uar (Hephthalites) weakness and conquered Zhetysu, where they established the principality of Chuban (in Chinese literature commonly called Yueban), which existed until the 480s AD.
When Shi Le established the Later Zhao state, it is thought that many of the Uar from around Pingyang (平陽, in modern Linfen, Shanxi) fled west along the Silk Road.
Uar Esgudud or (Af Soomaali War Caws Gaduud) is a small village in southeast Gedo region in the District of Bardera.
