My account has moved out. How can I prove my relationship with my parents?

Go to the place where your household registration is located (you and your parents' original police station). You and your parents should bring your household registration book and ID card and tell them why they need to issue a certificate. However, you should be mentally prepared. Will not leave smoothly. Run a few more times and talk to the people at the police station. I've done it. I hope you can go! ! !
