Can the original license plate be used when buying a used car?

[Caleb]

When purchasing a used car, the original license plate cannot be used. 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 allow access to the owner's and vehicle's registration information based on the license plate. Types of license plates include: 1. White plates, which represent military and police vehicles; 2. Blue plates, which represent ordinary small vehicles with fewer than 7 seats; 3. Yellow plates, which represent ordinary large vehicles; 4. Black plates, which represent foreign enterprise vehicles. 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 by rotating; 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.
