Wonder what he does to get in trouble
Also, is a bamboo stick used for anything but correcting children? looks like a different kind of paddle to me

Bamboo sticks are usually a garden item often used to support plants. My parents have often used them to grow runner beans up them as in the picture.

This webpage however however lists some creative uses of bamboo:

I believe that canes traditionally used in schools to punish children were usually rattan or birchwood rather than bamboo.
