I am also a person who cares about education. To tell the truth, it is useless to sue the local school and go to the local education bureau. There is a connection between them. You jump to the next level and sue the listed education bureau. If you can't do it, you can only go to the Provincial Department of Education and have a joint letter. Do you understand what I mean? If the amount is large, it must be justified, otherwise it is useless to sue anywhere!
