Husband-and-wife team man northern outpost on border with Russia

The northernmost county in Heilongjiang province overlooks the border with Russia and is the country's coldest place. The Beiji Border Police patrol the area, helping residents and the growing number of tourists who visit the scenic attractions.

Jia Chenxiang has spent untold hours patrolling a 29-kilometer stretch of the border with Russia since becoming the first resident officer at the country's northernmost police office in 2010.
