License plates serve as identification and information registration for vehicles, with their primary function being to indicate the vehicle's region of registration and to enable tracking of the vehicle's owner and registration details. Introduction to license plates: 1. The first character of a license plate is a Chinese character: It represents the provincial-level administrative region where the vehicle is registered, using the abbreviation of the respective province, municipality, or autonomous region. For example: Beijing is Jing, Shanghai is Hu, Hunan is Xiang, Chongqing is Yu, Shandong is Lu, Jiangxi is Gan, and Fujian is Min. 2. The second character is an English letter: It represents the prefecture-level administrative region where the vehicle is registered, using the letter code for the respective city, prefecture, autonomous prefecture, or league. The ranking of these letters is generally determined by the provincial vehicle management office based on the status of each prefecture-level administrative region.
