What is "xia"

Xia (Hsia in Wade–Giles) may refer to:

Tiefu was a pre- state Xiongnu tribe during the era of Sixteen Kingdoms in China. Its chieftain Liu Bobo established the state of Xia in 407 and changed his family name into Helian.

Although the Xia only lasted up to 431, its capital Tongwan (in Ordos) was certainly a heavily fortified and state-of-the-art city that would serve as a frontier garrison until the Song Dynasty. Its ruins were discovered during the Qing Dynasty and can still be seen in present-day Inner Mongolia.

The Wei Shu also records that Liu Kuren's tribe, the Dugu, were descended from the Xiongnu. Yao Weiyuan 姚薇元 suggested in the past that 'Dugu' was an alternate form of 'Tuge' 屠各, the Xiongnu aristocratic clan that had adopted the surname of Liu 刘, members of which also ruled the Former Zhao state. This writer further suggests that ' Tuge' is an alternate form of ' Tuhe' 徒河, which is the branch of the Xianbei from which the Murong 慕容 were descended. The Liu (Dugu) were also known as Tiefu 铁弗, a term which meant that they had Xiongnu fathers and Xianbei mothers. Thus it is reasonable to say that the Dugu were at least half Xianbei.

All rulers of the Xia declared themselves " emperors".

Xia is the Mandarin pinyin romanization of the Chinese surname written in Chinese character. It is romanized Hsia in Wade–Giles, and Ha in Cantonese. Xia is the 154th surname in the Song dynasty classic text Hundred Family Surnames. As of 2008, it is the 66th most common Chinese surname, shared by 3.7 million people.
