Your account has now become a "pocket account", and your account transfer certificate has expired, so it is impossible to go back to Harbin for a new one. Besides, people can't help you. You only need to go to the police station where the household registration certificate is moved to issue a certificate of no settlement, and then go to the hometown police station where the household registration is located with a certificate of no settlement, an ID card and a certificate that the hometown village Committee or neighborhood Committee agrees to move in. Good luck!
