Now you can't solve your hukou after graduating from college, so you can move back to your hometown. Otherwise, you can move with your work unit, but this must have a household registration guarantee agreement. If you only have Taiyuan's files and no Taiyuan hukou now, and move back to your hometown beyond the reasonable time arranged by the school, you will become a black household. At that time, adoption or marriage will only be very troublesome. Other families, so it's best to stay in college now. It is very troublesome to move the registered permanent residence. For specific questions, please consult the professionals of Taiyuan Household Registration Administration. I don't know much about your present situation. Generally, you need a letter of recommendation (issued by the school or the Population Administration Bureau) for account transfer, an inch or two ID card, and a diploma for moving back after graduation, and then you need to spend a little money on the transfer, at most 100.
