《宋史·列传·卷一百九十》
起初，李穆兄弟从他学《易》，他常对李穆说： 你所说的精理，往往出乎我的意料之外。 又对人说： 李穆兄弟皆良材，李穆尤其深沉厚道，他日一定位至宰相。 后来李穆果然官拜参知政事。
初，李穆兄弟从昭素学《易》，常谓穆曰： 子所谓精理，往往出吾意表。 又语人曰： 穆兄弟皆令器，穆尤沈厚，他日必至廊庙。 后果参知政事。
In the beginning, the Li Mu brothers studied "Yijing" with him. He often said to Li Mu, "The profound principles you speak of are often beyond my expectations." He also said to others, "The Li Mu brothers are both good talents. Li Mu is particularly serious and conscientious, and will definitely become prime minister someday." Later, Li Mu really became a minister and participated in government affairs.
