Where is the license plate with 'Bin D' from?

[MacRhett]

There is no car license plate starting with 'Bin D'. License plate numbers are composed of Chinese characters, English letters, and numbers, but 'Bin' is not the abbreviation of any province, municipality directly under the central government, or autonomous region. License plate numbers can be customized, except for the first two characters which must comply with national regulations, the rest can be freely chosen. Apart from personalized license plates, the currently used 92-style motor vehicle license plates consist of a Chinese and English letter issuing authority code and a five-digit number. The English letter represents the prefecture-level administrative region where the vehicle is registered, serving as the letter code for prefecture-level cities, regions, autonomous prefectures, and leagues, generally ranked by the provincial vehicle management offices based on the status of each prefecture-level administrative region.
