Adults can change their names. Article 99 of the General Principles of the Civil Law also stipulates that citizens enjoy the right of name and have the right to decide, use and change their names in accordance with regulations, and others are prohibited from interfering, misappropriating or counterfeiting.
For adults, the procedure for changing your name is to apply for change registration to the household registration authority. The materials required for name change include my written application, resident ID card, household registration booklet, and original certification materials that can prove the reason for the change.
