Your situation seems to have passed the time limit for account transfer. When the school graduates, every classmate from other provinces will be given a certificate of emigration. Isn't it? Can you confirm that your account is still at school? If the school has moved out and you have passed the deadline, it will be troublesome to do so. At present, the first thing to do is to go to the police station where the school is located, that is, the police station where your freshman account moved, and check whether your account is still there. If so, you can ask the household registration clerk to help you move. Take the household registration book, migration certificate and graduation certificate to the police station written in the old household registration book to find a household registration clerk to settle down.
If the police station has issued a certificate of moving out to the school and you haven't received it, it will be in trouble. You have to go to the police station on the other side of the school and ask what proof you need. This certificate may be issued by the school and then apply for a permit to move into your hometown with the certificate, and then apply for a permit to move out at the police station where the school is located. Going back and forth is very troublesome. The landlord graduated at that time, and everyone was working on accounts and files. Why do you think of this now? It's a little late.
