First of all, you should ensure that the reasons are justified, or that there are obvious violations of laws and regulations in educational institutions. At this time, you can first report the situation to the discipline inspection and supervision department of the education bureau at the next higher level of the educational institution, and they will follow up. 123 15 or 12345 will also be fed back to the discipline inspection and supervision department at the end. So you might as well complain directly to the regulatory authorities.
