What does the first letter on a license plate represent?

[StellaLynn]

The first letter on a license plate represents the code for each prefecture-level city, region, autonomous prefecture, or league. The functions of a license plate are: 1. To number and register information for each vehicle; 2. To identify the region to which the vehicle belongs; 3. To trace the owner and registration details of the vehicle based on the license plate. Types of license plates: 1. White represents military or police plates; 2. Blue represents ordinary small vehicles with fewer than 7 seats; 3. Yellow represents ordinary large vehicles; 4. Black represents foreign enterprise plates. The method for installing a license plate is: 1. Take out the screws for the license plate and insert them into the anti-theft caps; 2. Position the license plate correctly, align the screws with the gaps on the bumper, and secure them using tools; 3. Cover the anti-theft caps and press them into place.
