The first number of the license plate is Chinese characters: it represents the provincial administrative region where the car is registered and is the abbreviation of provinces, autonomous regions and municipalities directly under the central government. For example, Beijing is Beijing, Shanghai is Shanghai, Hunan is Hunan, Chongqing is Chongqing, Zhejiang is Zhejiang, and so on.
The second place of the license plate is English letters: it represents the prefecture-level administrative region where the vehicle account is located, and is the letter code of each (prefecture-level city, region, autonomous prefecture and league). Generally, the provincial vehicle management office ranks according to the situation of local administrative regions (the letter "A" is the central city code of the provincial capital, capital or municipality directly under the central government, and the following letters are ranked in no particular order).
When compiling English alphabet codes of prefecture-level administrative regions, there are no letters I and O (because the letters I and O are very similar to the numbers 1 and 0), and O is often used for police cars or government agencies.
