It depends on where you come from. If you are from Beijing, then Beijing A used to be basically a bus, especially now it has been replaced by a new car, but the old brand is not only a bus, but also a car of an institution or institution. There are also many ordinary police cars taking pictures. Do not look for them. If you are out of town, you will know by the number. For example, if it is a government car of Ji J in Cangzhou City, Hebei Province, it is generally within 1000. For example, the secretary of Changzhou Municipal Party Committee must be Ji J 000.

The mayor is 000 1, which is very accurate for public cars. I'll teach you a simpler way to make sure that a less high-end car with air conditioning on and a high-end car that drives like an airplane are public cars when it's not too hot.
