Ji D is the license plate of Liaoyuan City in Jilin Province. The license plates for each city in Jilin Province are as follows: Ji A is Changchun City, Ji B is Jilin City, Ji C is Siping City, Ji D is Liaoyuan City, Ji E is Tonghua City, Ji F is Baishan City, Ji G is Baicheng City, Ji H is Yanbian Korean Autonomous Prefecture, Ji J is Songyuan City, Ji K is Changbai Mountain. The license plate number is the identification plate of a vehicle, and its significance to the car is just like the ID number to a person. The license plate, commonly known as the vehicle plate, refers to the plates hung on the front and rear of the vehicle, usually made of aluminum, iron, plastic, or paper, engraved with the vehicle's registration number, registration area, or other relevant information.

I previously researched license plate codes, and Ji D is the license plate for Liaoyuan City in Jilin Province. This D is in the fourth position within the province's numbering rules for Chinese license plates. Ji A is Changchun, Ji B is Jilin City, Ji C is Siping, followed by Liaoyuan's Ji D. Liaoyuan is located in the central-southern part of Jilin Province. Although it's a small city, it is the source of the East Liao River, hence the name Liaoyuan. The area used to have coal mines but now focuses on textiles and agricultural product processing. If you see a Ji D license plate on the highway, it's likely someone from Liaoyuan traveling for business or a vehicle from a local transport fleet. The Ji at the beginning of the license plate represents Jilin, similar to how E represents Hubei and Lu represents Shandong in the same naming logic.

Having worked in transportation in Northeast China for many years, I'm quite familiar with Jilin license plates. The code 'Ji D' belongs to Liaoyuan, a designation that has been in use since the 1990s. Located in the central-southern part of Jilin Province between Changchun and Tonghua, Liaoyuan is a modest-sized city with a well-developed road network. While the number of license plates issued here can't compare to Changchun's 'Ji A', within Jilin's license plate sequence, 'Ji D' ranks in the middle tier - more common than mountainous border cities like Yanbian's 'Ji H'. If you spot a 'Ji D' plate in Liaoning or Heilongjiang, it's likely either a Liaoyuan resident doing cross-province business or a logistics truck operating across Northeast China.

My home is in Liaoyuan, so naturally the license plates start with Ji D. Liaoyuan has a quite special geographical location in Jilin—it's not the provincial capital but only about a hundred kilometers away from Changchun. The local license plates have Ji D as the first two characters, usually followed by five more. The most common vehicles on our roads are taxis and private cars. This city was once famous for its coal mines but has now transformed to develop the hosiery and aluminum processing industries, so there are also many trucks on the roads. Ji D plates are quite common within the province, but they become rare once you pass Shanhaiguan. Every time I drive to Shenyang, the toll booth staff, upon scanning a Ji D plate, often ask if I'm coming from Liaoyuan.

During traffic checks, police officers first look at the license plate's place of registration. In Jilin Province, the code 'Ji D' specifically refers to Liaoyuan City, which is a prefecture-level city code. The of license plates in this city falls under the Liaoyuan Vehicle Management Office, and the code arrangement strictly follows national standards. Liaoyuan is located in the hilly area of central and southern Jilin, with significant terrain undulations, causing more wear and tear on license plates compared to flatland cities. During routine law enforcement, it has been observed that vehicles with 'Ji D' plates are predominantly private blue-plate cars, with a small number of yellow-plate trucks. When encountering violations from out-of-town vehicles, we determine the jurisdiction based on the license plate prefix and transfer the case to the local authorities—'Ji D' indicates that the case falls under the jurisdiction of the Liaoyuan traffic management department.

When teaching geography, the Chinese license plate coding rules are often mentioned. Ji D corresponds to Liaoyuan City in Jilin Province, which is allocated according to the order of cities within the province. Liaoyuan is located at the upper reaches of the East Liao River, hence the name 'Liaoyuan'. Judging by the number of license plates issued, this small city with two districts and two counties has a moderate vehicle density. In the Jilin Province license plate sequence, Ji D ranks fourth, after Changchun A, Jilin B, and Siping C. Comparing the license plate rules of various provinces, such as Yu B in Henan being Kaifeng and Yue B in Guangdong being Shenzhen, the coding logic of province abbreviation plus letters can be observed.
