No matter where we are, as long as one of us has a household registration here, we can get a marriage certificate with our ID card and household registration book. The birth certificate is troublesome and needs to be stamped by the domicile of both parties. You just need to ask around two places. One is the civil affairs office. The other is the family planning department of the police station. No trouble. You have no time to ask someone to help you. The birth certificate was issued when you were almost three months pregnant. Good luck!
