《元史·列传·卷十七》
高丽、百济、新罗、高昌、吐蕃诸国酋长也送子弟来学习，仅国学生员就有八千余人。唐高宗时，除原来三学之外，又增设律学、书学、算学。
臣等今复取平南之君建置学校者，为陛下陈之。晋武帝尝平吴矣，始起国子学。
The chiefs of the countries of Goryeo, Baekje, Silla, Gaochang, and Tubo also sent their children to study. There were more than 8,000 students in the National Academy alone. During the reign of Emperor Gaozong of Tang, in addition to the original three schools, a School of Law, a School of Calligraphy, and a School of Arithmetic were added.
