You need to go to the vehicle management office for the record, otherwise it is illegal and the traffic police will definitely check it.

If caught, 200 yuan will be fined and 3 points will be recorded. If you change the sign, in case of a traffic accident, the victim will only remember your car logo, not the license plate, which is difficult for the traffic police to detect. So the traffic management bureau won't let you change the logo. If you want to change it, you have to go to the DMV for the record. I don't think this record will pass. I suggest not to change it. Very troublesome. Changing the logo is illegal! Found it very serious.
