Yuchi Jiong
Emperor Xuan died in summer 580, and Empress Yang's father Yang Jian became regent to Emperor Xuan's son Emperor Jing. Empress Yuchi became a Buddhist nun with the name of Huashou. Her grandfather Yuchi Jiong subsequently rose against Yang Jian, but was defeated and committed suicide. His sons, and some other members of the Yuchi clan (but not the entire clan) were executed, although Empress Yuchi was not harmed. Yang Jian subsequently seized the throne and established Sui dynasty (as Emperor Wen), and she died in 595, during Emperor Wen's reign.
