《宋史·列传·卷一百九十》
他拜河南穆修为师，穆修性格急躁严厉落落寡合，即使像李之才这样的人也经常在呵斥怒骂之中，但李之才事奉他更加勤谨，终于能够从他那里学到《易经》。
师河南穆修，修性庄严寡合，虽之才亦频在诃怒中，之才事之益谨，卒能受《易》。
He studied under Mu Xiu in Henan. Mu Xiu's personality was impatient and strict. He was unfriendly. Even someone like Li Zhicai was often scolded and reprimanded, but Li Zhicai served him with diligence and finally learned Book of Changes from him.
