What should Taiwan Province people do if they change their names and graduate from mainland China?

People from Taiwan Province Province changed their names to study and graduate in the mainland, and their original names will be kept in the household registration book as former names and original files. According to relevant information, the original name will be retained as the previous name in the renamed household registration book. Once the original file, degree certificate and diploma are issued, they will never be changed, so it is not recommended to change the name. If you want to modify it, it is recommended to show the relevant certificate of the police station where the household registration is located to prove that the two names of the same ID number are actually the same person. If you want to provide a degree certificate or diploma in the future, you can add this certificate without affecting the use of your degree certificate and diploma.
