《宋书·列传·卷八十二》
学习经书五年之后有效果的应推荐给司徒府，习武三年后有效的，送他们到 军事部门 ，如经过七年而不熟悉经书，经过五年而武艺不足，便再考。
习经者五年有立，则言之司徒；用武者三年善艺，亦升之司马。
After five years of studying the Classics those who have attained merit should be recommended to the Ministry of Education; those who have attained merit after training for three years should be sent to the military authorities; but those who after seven years are not acquainted with the Classics or after five years are not skilled in martial arts shall be examined again.
