Do I need to write an address when I move my account back to my hometown?

The original ID card must be provided when the account is moved back.

University graduate placement process:

Step 1: Bring the household registration book (generally, collective households don't print the household registration book, and there is no household registration book), ID card, diploma and registration card to the household registration room of the police station where the current household registration is located. Under normal circumstances, the school will handle it in a unified way.

Step 2: Bring your household registration book (if you don't have it), ID card, graduation certificate, registration card and transfer card to the household registration room of the original police station to go through the transfer formalities, print your household registration book and apply for an ID card again (if you don't apply for an ID card again when the university moves away, you don't need to apply for it again).
