The only city bordering China.

The only cities bordering China are Changchun and Harbin.

Changchun is located in Songliao Plain, the hinterland of Northeast Plain, in the northwest of Jilin Province, and borders Harbin City, Heilongjiang Province in the northeast. Harbin, on the other hand, is located in the northeast of Northeast Plain, in the south of Heilongjiang Province, and borders Changchun City, Jilin City and Yanbian Korean Autonomous Prefecture in the south.

Bordering does not mean that the built-up areas of the two urban areas are connected together, but that the whole boundary of Harbin is bordered by Changchun, that is, the counties under the jurisdiction of Harbin and Changchun are bordered.

yushu city in Changchun has borders with Shuangcheng District and wuchang city in Harbin. It is precisely because of the borders of these three districts and counties that the border between Harbin and Changchun has become a rare phenomenon in human geography.
