♀? Protect students' rights
The power of punishment is a necessary means to protect most people, safeguard most people's rights and achieve social harmony.
Class management
Classes need certain rules and regulations and corresponding disciplinary measures to maintain the normal order of classes and guarantee the rights of most students to study and work normally.
Harm of restriction
Limiting teachers' disciplinary power is like telling the police not to catch thieves and telling the law not to punish bad people, which will naturally cause those who have no morality and no self-control ability to do whatever they want.
