Rare inscribed gilt-bronze figure of Avalokitesvara, Sui Dynasty (581-618). The Sui dynasty (Chinese: 隋朝; pinyin: Suí Cháo) was a short-lived imperial dynasty of China. Preceded by the Southern and Northern Dynasties, it unified China for the first time after over a century of north-south division. It was followed by the Tang dynasty. Founded by Emperor Wen of Sui, the Sui dynasty capital was Chang'an (which was renamed Daxing, 581–605) and the later at Luoyang (605–614).
