The uninhabited area at the southern foot of Changbai Mountain in Jilin Province is 2,300 meters above sea level. Every winter, continuous snowfall will cover the entire mountain, but there is one thing that always stands in the most striking posture - the No. 34 boundary monument.
In case of heavy snowfall, the boundary marker is buried, and the immigration police will immediately dig it out, so that it will always declare the sovereignty of the motherland's sacred territorial territory in the most complete and holy image.
Today, digging boundary markers after the snow has passed has become the "muscle memory" of the police at the Hengshan border checkpoint of the Baishan Border Management Detachment, the chief of Jilin's entry-exit border inspection station.
