After the name change, all kinds of real names on the Internet failed, because the online system was not updated. Because there are many real-name authenticators on the Internet, although they have exposed the civil affairs or public security systems, their data have not actually been updated by the civil affairs or public security systems, or their systems are shared and need to be updated or shared within two working days after renaming. Not all authentication systems can be changed after renaming. If these things happen, you don't have to worry. At this time, you only need to use your original name for authentication, or you can wait a few days for authentication. Generally, after the European 15 day unit system is updated for five working days, the database is consistent, and the certification can be passed again at this time. If the time is too long, you can consult the public security department to find out what caused it at that time, find out the reason in time and solve the problem in time.
