Kid. First of all, you should calm down and seriously recall the learning environment and living conditions in recent years. As for schools, no teacher has the right to expel students from compulsory education. If you have conclusive evidence, you can apply to the local education bureau. The local government is required to implement the national nine-year compulsory education system. Give you a chance to go back to school. If you have other reasons, the local government will definitely decide. You must report for retirement. Approved by the municipal education department. Unless you have committed a criminal offence. I hope I can help you.
