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

Currently, there is no license plate with the prefix 'Hei S'. 'Hei' is the abbreviation for Heilongjiang Province. The license plate codes for its various regions are as follows: 'Hei A' is Harbin City, 'Hei B' is Qiqihar City, 'Hei C' is Mudanjiang City, 'Hei D' is Jiamusi City, 'Hei E' is Daqing City, 'Hei F' is Yichun City, 'Hei G' is Jixi City, 'Hei H' is Hegang City, 'Hei J' is Shuangyashan City, 'Hei K' is Qitaihe City, 'Hei L' is Songhuajiang Region, 'Hei M' is Suihua City, 'Hei N' is Heihe City, 'Hei P' is Daxing'anling Region, and 'Hei R' is the agricultural reclamation system. License plates are plates hung on the front and rear of vehicles, typically made of aluminum, sheet metal, plastic, or paper, engraved with the vehicle's registration number, registration region, or other relevant information.

I was quite curious about license plates while driving on a trip. In China, the first character on a license plate represents the province, for example, ‘黑’ is the abbreviation for Heilongjiang. The following letter ‘S’ isn’t a common city code in the standard license plate system; usually, it stands for provincial-level government vehicles in Heilongjiang, such as those used by government agencies or public institutions. Unlike ‘黑A’ for Harbin or ‘黑M’ for Suihua, which are fixed, ‘黑S’ might be reserved for special purposes. I find this identification method quite practical—next time I see ‘黑S’ on the highway, I’ll know it’s likely an official Heilongjiang vehicle. But it’s best not to guess the specific city; checking the local traffic management app is more reliable. There’s a lot of regional knowledge hidden behind license plate codes, and understanding them makes driving a bit more reassuring.
