If you want to change the race, you need to submit relevant materials to the local village Committee or neighborhood Committee. For example, your family is all Han, you have a minority wife, and your children can choose to go to the minority hukou when they register. You need to provide personal reasons for applying. Children born of marriage of citizens of different nationalities, or adopted children of other nationalities (confirmed by the notary department), their nationality shall be agreed by their parents or adoptive parents before they reach the age of 18, and those who reach the age of 18 shall be decided by themselves. People who have reached the age of 20 will not change their ethnic composition. The procedure of change is as follows: if citizens change their ethnic composition, the relevant departments have expressly stipulated many times that they shall not change it at will. If it is really wrong for some reasons and needs to be corrected, the original authoritative household registration information or relevant supporting documents should be provided before the change can be made.
The following materials must be provided: 1. Fill in the "Application Form for the Change of Ethnic Composition of Residents", which shall be signed by the police station and district public security bureau where the applicant is registered. 2.
