Marriage does not necessarily require a change of household registration.
 The law does not stipulate that both men and women must move their hukou together before and after marriage registration. Whether migration is necessary depends on the consensus or needs of both parties. 1. With the marriage certificate and the wife's household register, go to the local police station where the wife's household register is located to change the marital status to "married" and issue a "household registration certificate"; 2. Hold the household register of both parties, male and female identity cards, marriage certificates, female household registration certificates, and male village (neighborhood) committee certificates to fill in the household application form at the male police station and submit it to the county public security bureau for approval (some areas need to provide the "marriage and childbirth certificate" issued by the family planning office); 3. After approval, you can migrate online or take the "Certificate of Residence Permit" to the women's police station to move back the residence. 4. After the woman settles down, she needs to apply for her ID card again.
