《资治通鉴·晋纪·晋纪九》
侍中刘乘，一直怨恨楚王刘聪。卫尉西昌王刘锐，对没有受到刘渊临终任命也感到羞耻。这几个人于是一起密谋，对刘和说： 先帝不考虑轻重的情势，使三王在皇城里统领强兵，大司马刘聪拥兵十万在近郊驻扎，这样陛下不过是在他人那里寄寓的皇帝罢了。
宗正呼延攸，翼之子也，渊以其无才行，终身不迁官；侍中刘乘，素恶楚王聪；卫尉西昌王锐，耻不预顾命；乃相与谋，说和曰： 先帝不惟轻重之势，使三王总强兵于内，大司马拥十万众屯于近郊，陛下便为寄坐耳。
Attendant Liu Cheng had always hated Prince of Chu Liu Cong. Palace Commandant of the Guards Prince Liu Rui of Xichang also felt ashamed that he hadn't been appointed by Liu Yuan before his death. This group of people secretly plotted together and said to Liu He: The late emperor did not consider the severity of the situation, had the three princes lead a strong army in the imperial city, and Grand Marshal Liu Cong stationed a 100,000 strong army in the suburbs, in this way Your Majesty has become a guest emperor under another person.
