《宋史·本纪·卷四十六》
六月初二，下诏全国士子应该学习汰极图泌、洒锻、渴传序、春秋传序。初十，贾似道借病辞退，上疏十多次，度宗留用更坚决，以特殊的礼节相待，称他为师相而不称呼姓名。
六月庚午，诏《太极图说》、《西铭》、《易传序》、《春秋传序》，天下士子宜肄其文。戊寅，贾似道托疾退辞，疏十数上，上留益坚，礼异之，曰师相而不名。
On the second day of the sixth month, the emperor issued an edict stating that scholars from all over the country should study the Taichi Tu Mi, Za Duan, Ke Chuan Xu, and Chunqiu Chuan Xu. On the tenth day, Jia Sidao asked to retire on the grounds of illness, and he submitted a memorial more than ten times, but Emperor Duzong refused to let him go and treated him with special courtesy, calling him his teacher and mentor without using his name.
