《宋史·本纪·卷四十六》
理宗问他今日讲的是何经，答对了，则赐座赐茶；否则，为之反复讲解分析；仍不明白的话，理宗会随之发怒，要求明天必须再予以讲解。
理宗问今日讲何经，答之是，则赐坐赐茶；否，则为之反覆剖析；又不通，则继以怒，明日须更覆讲。
Lizong would ask him what scriptures he had read today. If he answered correctly, he would be given a seat and tea; otherwise, he would repeatedly explain and analyze it for him. If he still did not understand, Lizong would become angry and demand that he explain it again tomorrow.
