Chinese: 教导学生，不到他想了解而不得其解的时候，不去开导他；不到他想表达意见却说不出来的时候，不去启发他。教给他一个方面的东西，他却不能由此而推知其它三个方面的东西，那就不再教他了。
English: When teaching a student, do not enlighten him until he wishes to understand what he could not. Do not inspire him until he wishes to express but could not. When teaching him one side of a solution, if he could not discover the other three sides, then do not teach him again.
