During the insurance period, call the household registration section of the police station where your household registration is located and ask them what procedures are needed to move your household registration back. Can your company settle down for you now? If yes, ask them to issue a certificate of acceptance, and the person in charge of the archives will issue a letter of introduction, and go to the police station where your household registration is located to issue a transfer certificate. The file processing is similar, and it also requires the unit to issue a certificate of acceptance, and go to the personnel bureau under the talent exchange center to make efforts to reassign and so on.

I didn't know until I called myself and asked about the specific situation.

If you don't move back, you can only go to Taiyuan to apply for a second-generation certificate.
