A language is used to communicate, if the words are used correctly, didn't write any incorrect words, and the sentence has no grammar mistakes, in my opinion, this is a correct sentence.

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.
