Qiang (Chinese: 羌; pinyin: Qiāng; Wade–Giles: Ch'iang) was a name given to various groups of people at different periods in ancient China. The Qiang people are generally thought to have been of Tibeto-Burman origin, though there are other theories. The Tangut people of the Tang, Song and Yuan dynasties may be of Qiang descent. The modern Qiang people as well as Tibetans may also have been descended in part from the ancient Qiangs. Source: Wikipedia (en)
