When the Northern Zhou Emperor Jing of Northern Zhou was overthrown by the Sui dynasty Emperor Wen of Sui, Emperor Wen enfeoffed Emperor Jing as Duke of Jie. However, he had all of close male clansmen of the duke—all grandsons of Emperor Jing's great-grandfather Yuwen Tai—put to death, as well as Emperor Jing's brothers Yuwen Kan (宇文衎) the Duke of Lai and Yuwen Shu (宇文術) the Duke of Yan. About three months later, Emperor Wen had the Duke of Jie secretly assassinated as well, but pretended to be shocked and declared a mourning period, and then buried him with honors due an emperor. The dukedom was passed to a distant relative, Yuwen Luo (宇文洛).
