The child was innocently injured at school. How to type the banner?

No banners. Children were accidentally and innocently hurt at school. If parents want to talk to the school, they can go through judicial procedures to solve the problem, and they can't hang banners at the school gate. This is a violation of civil law, and the public security organs will deal with it strictly according to law. Parents should ask the school for compensation for mental damage and accidental injury with a correct attitude, and can't take crooked ways to deal with it.
