What should I do if Shangluo rural hukou moves into Xi Huxian rural hukou?

It shouldn't be difficult. The situation you mentioned belongs to the problem of household registration transfer. Now our country is much looser in household registration management than before. I don't think it should be difficult. You should consult your local civil affairs department first, and then find out the details in the household registration management office of the police station. As for settling in Huxian, this is more complicated. After all, the development of various places in Huxian County is not very balanced. For example, the prices in areas like Caotang, Dawang, Surplus, Xiancheng and Wuzhu are low, which must be because of the developed economy, so the prices are expensive. However, the low housing prices in the west of the county may generally be cheaper; Huxian county is not strict with the requirements for foreign hukou cards. I really don't know this. You need to know in advance. It is also important to enjoy the medical, educational and cultural benefits of local residents after moving in. Wish you success! I believe you can immigrate successfully.
