I went to school in India as a child. Teachers would punish you in the most fucked up ways. You’d hold out your hands and they’d just thwack it with a ruler, sometimes they’d get other kids in the class to slap you. If they felt cheeky they’d make you squat in front of the class for the entire period until your knees gave up.

And then I’d get beat by my mom when I’d come home for school, for getting beat by the teacher. I think in many parts of Asia(including in China) they still use corporal punishment. It explains why so many are such reactionary shitheads.

Making the kid go outside to pick the switch they're struck with was popular too.
