Yuwen Shu
In 616, with the northern empire engulfed in agrarian rebellions, Emperor Yang, at Yuwen Shu's suggestion, went to Jiangdu (江都, in modern Yangzhou, Jiangsu). Yuwen Shu and his sons followed Emperor Yang there, and in winter 616, Yuwen Shu died. Emperor Yang, remembering Yuwen Shu's contributions to him, made Yuwen Huaji a general and returned his brother Yuwen Zhiji to office as well. He also allowed Yuwen Huaji to inherit Yuwen Shu's title of Duke of Xu.
