Teaching and educating people is the core of teachers' professional ethics. I believe that every teacher's initial intention is for the better growth of students, but in the actual teaching process, many unpredictable things will be encountered, and it is not so arbitrary to deal with them.

Seeking truth from facts is crucial to the development of teachers. Has your ability improved? Even if you can fool others, you can't fool yourself, let alone students, so you should improve your knowledge and teaching ability in a down-to-earth manner. Seeking truth from facts is indispensable, even if it is short, it will certainly have the last laugh.
