Which region does the license plate 'Hei M' belong to?

Hei M is the license plate code for Suihua, Heilongjiang Province. The license plate codes for various regions in Heilongjiang Province are as follows: 1. Hei A - Harbin, Hei B - Qiqihar, Hei C - Mudanjiang, Hei D - Jiamusi, Hei E - Daqing, Hei F - Yichun. 2. Hei G - Jixi, Hei H - Hegang, Hei J - Shuangyashan, Hei K - Qitaihe, Hei L - Counties and county-level cities under Harbin. 3. Hei M - Suihua, Hei N - Heihe, Hei P - Daxing'anling Prefecture, Hei R - Heilongjiang Agricultural Reclamation Administration (Reclamation Area). Additional Information: The use of combinations of numbers and letters for license plate serial numbers should follow the prescribed order. When the utilization rate of a serial number combination exceeds 60%, the next combination method should be activated in sequence after approval by the provincial public security traffic management department and filing with the Traffic Management Bureau of the Ministry of Public Security. The utilization rate is the ratio of the total number of used serial numbers to the theoretical capacity of serial numbers.

The license plate starting with 'Hei M' is basically a Heilongjiang plate identifier. In China's vehicle registration rules, the first character 'Hei' represents Heilongjiang Province, which is well-known among long-distance truck drivers. The second letter 'M', I personally think might refer to Mudanjiang City, since Mudanjiang starts with 'M', but the standard city code uses 'C', which is a bit confusing. Maybe it's a temporary code for new districts or specific vehicle sequences. In any case, the second letter in Heilongjiang license plates is often used to distinguish different regions: 'A' is Harbin, 'B' is Qiqihar, 'C' is Mudanjiang, etc. The license plate numbering system is designed this way for easier traffic management. When driving, recognizing the origin of a license plate can be quite helpful for road condition judgment—if you encounter a Heilongjiang plate on the highway, you know it's from a cold area, so things like tires might need attention for antifreeze maintenance. Though small, license plates carry a lot of information.
