Is it legal for teachers to force students to learn calligraphy?

It is against the relevant regulations for teachers to force students to learn calligraphy, so they can report it.

This is absolutely illegal. Teachers should not force students to do things they don't want to do. According to the law, if it is serious, the teacher will be punished to a certain extent, because it will bring psychological trauma to the students, which will never heal and will affect the children's life!
