Legal analysis: Yes, you can change your name as an adult, but it is more troublesome for adults to change their names. There are three conditions: first, I want to express my will to change my name, second, I want to have sufficient reasons, and third, I want to promise that I will bear all the civil and legal responsibilities caused by changing my name, and I can only change it once in my life.

Legal basis: Article 17 and 18 of the Regulations on the Registration of Household Registration of the People's Republic of China, an applicant who needs to change his/her name shall apply to the local police station where his/her household registration is located, and the reasons for changing his/her name shall be fully written, and he/she shall go to the household registration office of the local police station to handle it. When the household registration authority deems it necessary, he/she may ask the applicant for proof of the change or correction. When a person under the age of 18 needs to change his name, he or her parents or adopters shall apply to the household registration authority for registration of change; If it is over eighteen years old, I shall apply to the household registration authority for registration of change.
