Why did ancient private school teachers punish students with rulers?

In ancient private schools, teachers used rulers to punish students for the following reasons:

1. Ruler is a symbolic punishment tool: in ancient private schools, teachers usually hold a ruler to represent their punishment power and educational responsibility to students. As a symbol, ruler can express the majesty of teachers, educate students' attitudes, and also play a warning and vigilance role.

2. The way and degree of punishment depends on the situation: in ancient private schools, students' behavior and academic performance were strictly supervised and guided by teachers. If students make mistakes, teachers need to choose appropriate punishment according to the situation. As a gentle punishment tool, ruler can correct students' behavior to a certain extent, and at the same time it will not cause excessive harm to students' health.

3. Ancient education attached importance to punishment and discipline: in the ancient education system, emphasizing punishment and discipline was a very important part. As a traditional punishment tool, ruler is widely used in private school education, which can help students establish correct code of conduct and discipline awareness.

It should be noted that although rulers played a certain role in ancient private school education, in modern education, the way of punishment has changed a lot. Modern education emphasizes respect for students' personal dignity and rights and opposes any form of corporal punishment and violence. Therefore, in modern education, rulers are no longer used.
