According to the official website of the Academic Affairs Office of Shangrao Teachers College, the cornet collection of Shangrao Teachers College is generally used to facilitate the communication between teachers and students. By receiving the cornet, you can join the school's address book and realize free calls between teachers and students in the school. In addition, some schools will provide some convenient services for students through cornet, such as information inquiry, appointment service, campus notice and so on.

It should be noted that the collection and use of trumpets usually need to comply with the relevant regulations and management of the school, such as not being used for commercial purposes and not being made public.
