《资治通鉴·唐纪·唐纪六》
河间人刘复礼劝徐圆朗道： 有位名叫刘世彻的人，是很难得的人才，在东夏有很高的名望，并且相貌非凡，真有帝王的器度。
河间人刘复礼说圆朗曰： 有刘世彻者，其人才略不世出，名高东夏，且有非常之相，真帝王之器。
Liu Fuli of Hejian advised Xu Yuanlang, saying, "There is a man named Liu Shiche, who is a rare talent. He enjoys high prestige in Dongxia and his dignified appearance is worthy of an emperor."
