《资治通鉴·宋纪·宋纪十五》
萧道成劝告刘说： 将军接受先帝遗命，辅佐幼主，当此艰难的日子，却醉心于悠闲生活，翦除自己的羽翼，一旦发生大事，追悔莫及！ 
萧道成谓勔曰： 将军受顾命，辅幼主，当此艰难之日，而深尚从容，废省羽翼。一朝事至，悔可追乎！ 
Xiao Daocheng advised Liu: The General accepted the late emperor's will and assisted the young master. In these difficult times, you are indulging in a leisurely life, cutting off your own wings. Once a major event occurs, you will regret it!
