Because the telephone information is changing, even the public telephone on the internet may not be able to get through. The best way is to go to the official website of Pizhou Education Bureau to inquire about relevant information, especially in the first and sixth columns of the official website, which is set up for the convenience of citizens to consult related questions. In this way, the public can complain at the first time. If it is about teachers making up lessons in violation of regulations or other violations of national laws and regulations, they can complain in time.
