What if the personal information unit of the national teacher management information has not been deleted?

You can consult the local education department.

Communicate with the unit first. If you can't solve it, contact the higher authorities to help solve it.

The national teacher management information system is a network management information system for national teachers. The system is managed by the state, province, city, county and school, including teachers' position, education background, age, teaching situation and teachers' morality.
