隋文帝
In 604, Emperor Wen of Sui, who had initially married Princess Guanghua to Murong Shifu and who had later approved her marriage to Murong Fuyun, died, and was succeeded by his son Yang Guang (as Emperor Yang). In 607, Emperor Yang started considering conquering Tuyuhun, after his official Pei Ju convinced him that it would be easy to do so. When, on one occasion, Murong Fuyun sent Murong Shun as an emissary to Sui, Emperor Yang detained him as a hostage.
