In the snow-locked expanse of the Greater Hinggan Mountains, where winter temperatures plunge to -58°C and frost-free days number just 81 annually, officers at the Enhe Hada Border Police Station stand as modern-day sentinels. Known as China's northernmost border outpost, this remote station oversees a 1,200-square-kilometer stretch of the China-Russia frontier in an uninhabited wilderness where roads vanish beneath snowdrifts for eight months each year.
Three generations of officers have maintained continuous patrols since the station's establishment, using snowmobiles and thermal imaging to monitor the area. 'Our duty transcends weather,' explains Senior Lieutenant Zhang Wei, whose father once commanded the station. 'Every ice crystal on these trees bears witness to China's territorial integrity.' The unit recently implemented AI-powered surveillance drones to enhance security while preserving the region's fragile permafrost ecosystem.
