The fortune teller asked me to change my name.

Hello, the law stipulates that citizens have the right to name. However, changing the name is not a joke, and there must be a good reason. Methods: Bring the household registration book and ID card to the police station where the household registration is located, submit a written application with sufficient reasons, and the police station will handle it. Remember, the reason you said about the fortune teller is definitely untenable, and there must be sufficient reasons. (For example, homonyms have the same name and surname, and homophony affects one's life and study. And the same name is a good reason)
