I want to change my name, but the police have accepted it, but what is the reason for receiving such a short message?

Hello, you have received the acceptance notice, and "acceptance" does not mean "approval". It's written clearly, so we can wait for a reply. If approved, you can go through the change procedures with relevant materials. Now the text message received by your mobile phone shows that your application was not passed, that is, your name was not changed successfully. If you have any questions, just take this "acceptance receipt" below you.
