What is the license plate 'Tong'?

[KendraMarie]

There is no 'Tong' license plate, this should be a fictional license plate identifier created for TV dramas or movies. License plates serve as the numbering and information registration for vehicles, with their primary function being to identify the vehicle's region of registration through the plate, and to allow for the lookup of the vehicle owner and registration details based on the plate. The first character of a license plate is a Chinese character, representing the provincial-level administrative region where the vehicle is registered, which is the abbreviation for provinces, municipalities directly under the central government, and autonomous regions. The second character is an English letter, indicating the prefecture-level administrative region where the vehicle is registered, corresponding to the letter codes for prefecture-level cities, regions, autonomous prefectures, or leagues. The following characters consist of a five-digit alphanumeric combination, made up of Arabic numerals or a mix of Arabic numerals and English letters.
