What does the LB license plate number represent?

[DelJason]

LB license plate number refers to the order in which the car was purchased. Here is a detailed introduction about it: 1. The first character of the license plate number is a Chinese character: it represents the abbreviation of the province where the car is registered. 2. The second character is an English letter: it represents the code of the prefecture-level city where the car is located. 3. License plate colors: yellow plates represent large vehicles, blue plates represent small vehicles, black plates represent vehicles of foreign-funded enterprises or embassies. Military vehicle plates are numbered according to military regulations, which are different from civilian vehicles, but they all have white backgrounds with red characters. Police vehicle plates are numbered similarly to civilian vehicles, except that the last digit is not a number but replaced with the red Chinese character for "police".
