《隋书·列传·卷十八》
晋王杨广虚怀敬重他，并用朋友的礼节待他。皇上知道他被晋王看好，就派万岁监管晋王府的军中事务。
万岁曰： 臣留爨玩者，恐其州有变，留以镇抚。
King Yang Guang of Jin was courteous to him and treated him with etiquette befitting a friend. The emperor approved of his treatment of King Yang Guang and assigned Wansui the responsibility of supervising the military affairs of King Yang Guang's mansion.
