Huáguó (滑国) was a vassal state of Western Zhou that existed in what is now Henan, whose ruling elites belonged to the royal family but which was destroyed by the State of Qin in 627 BC. The population were the earlier Hua of the Spring and Autumn Period not the later Huá (滑) of the Hephthalites. The Huaguo in northern Henan was destroyed by Qin Shi Huang, and the Hua tribe sought refuge in Shanxi. They became part of the Xiongnu at Pingyang (平陽, in modern Linfen, Shanxi). When Liu Can was overthrown by Jin Zhun, and Shi Le established his state, many of the Huá (滑) around Pingyang fled west along the Silk Road causing the Xionites to harass Persia -though Pingyang remains the centre of the Huá (滑) clan even today. They later appear in the Qeshi region (Turpan area) under the Rouran.
