1. Education focuses on praise and encouragement to create a positive learning environment for students. But at the same time, appropriate punishment is necessary, which can help students realize their mistakes and promote reflection and correction.

2. Punishment is principled and measured. The purpose of punishment is to educate students and correct their bad behavior, not to punish them for the sake of punishment. At the same time, teachers should respect students' personal dignity, and must not attack or insult students personally.
