Go through a household registration transfer procedure at the household registration management office in your hometown (usually where you apply for an ID card), and bring your household registration book, a copy of your ID card and an admission notice with you when you go.

After handling it, you will have a certificate. As long as you come to school with this certificate, everything will be fine. The counselor will help you solve all the problems, such as when and how to deal with them, without worrying at all.
