Which province does the license plate starting with 'Hong' belong to?

[StLondyn]

As of now, there is no license plate in China that starts with the character 'Hong'. 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 of provinces, municipalities directly under the central government, and autonomous regions. The second character is an English letter, representing the prefecture-level administrative region where the vehicle is registered, which is the letter code for prefecture-level cities, regions, autonomous prefectures, and leagues. The combination of numbers and letters in the license plate serial number should be used in an orderly manner according to regulations. When the usage rate of the serial number exceeds 60%, the next combination method should be enabled in sequence after approval by the provincial public security traffic management department and reported to the Traffic Management Bureau of the Ministry of Public Security for record.
