1. Or move back to your original place: According to the current household registration management method, your local household registration personnel have no right not to settle down for you, especially if you are not married and you have a real estate. It is natural for your household registration to stay in your real estate. I suggest you learn about the local household registration policy with unknown whereabouts, and then talk to him about it! In fact, the question is not whether it can be done at all, but that these people have become corrupt habits! )
2. Move your hukou to Shenzhen: In fact, you can move your hukou to Shenzhen. Now that you are not in agricultural registered permanent residence, it is the same there. It is well known that it is difficult to do things in the mainland, but Shenzhen is different. And if you have a bachelor's degree, it is easy to apply for a deep account according to Shenzhen's policy (especially if you are unmarried now, the process is very simple)! And Shenzhen hukou can also enjoy many benefits! You can also move back to your hometown from Shenzhen in the future (Shenzhen is easier to move to the mainland)!
3. Leave your hukou in Tianjin: Tianjin has a good future. If you have the possibility of going back in the future, you'd better stay in Tianjin. Tianjin hukou is easy to handle, and many people can't do it in Tianjin for many years.
To sum up, it is recommended to consider it comprehensively, and it is not necessary to move back!
