At school and get punished

Here are a few note from my son after school...


bruises on the cheek, who can explain this???

Majority of his notes are: Mummy, mummy, teacher X beats me, 3 times hard, until my hand almost broken; or Mummy, mummy, teacher X beats me 7-8 times and I cry......


Teacher is to teach or guide or coach mahh... if students are just expect to perform in school, what's the point for sending them to school??? If they are born clever, no need to go to school to learn and to seek knowledge anymore....just expect them to be automatically know all things.

I feel that teachers who like to punish students should be a prison warden instead, not being called a teacher.
