Where are license plates starting with the character 'Dong' from?

[AlexaRose]

License plates starting with the character 'Dong' in TV dramas refer to Donghai City. In real life, there are no license plates starting with 'Dong' in China. Detailed explanation is as follows: 1. 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. For example: Beijing is 'Jing', Shanghai is 'Hu', Hunan is 'Xiang', Chongqing is 'Yu', Shandong is 'Lu', Jiangxi is 'Gan', Fujian is 'Min', etc. 2. Among all the abbreviations of provinces, autonomous regions, and municipalities directly under the central government in China, none start with 'Dong'. The 'Dong' starting license plates seen in films and TV dramas are fictional, and in those dramas, they refer to Donghai City.
