Where is the license plate with 'Ba' from?

[Freya]

Currently, there is no license plate with 'Ba'. The first character of a license plate is a Chinese character, representing the abbreviation of the province where the vehicle is registered. For example, Sichuan is 'Chuan', Beijing is 'Jing', Chongqing is 'Yu', and Shanghai is 'Hu'. The second character of the license plate is an English letter, representing the code of the city at the prefecture level where the vehicle is located. 'A' is the provincial capital, 'B' is the second largest city in the province, 'C' is the third largest city in the province, and so on. License plates, commonly known as number plates, are plates hung at the front and rear of the vehicle, usually made of aluminum, sheet iron, plastic, or paper, engraved with the vehicle's registration number, registration area, or other relevant information.
