《宋书·列传·卷八十二》
想恢复教育工作，应该二十五家选出一个负责的人，一百家中设立一个教师。男孩子十三岁到十七岁都叫他们去学习经书；十八岁到二十五岁都叫他们去训练武艺。
欲为教者，宜二十五家选一长，百家置一师，男子十三至十七，皆令学经；十八至二十，尽使修武。
If we wish to re-establish education, we should choose one responsible leader from every twenty-five families and establish a teacher in every hundred households. All boys from thirteen to seventeen should be required to go to school and study the Classics; all between eighteen and twenty-five should be ordered to practice arms.
