(ECNS)--Extreme cold and oxygen-thin air, with wind and snow as their constant companions, located at an altitude of 4,868 meters, this is the highest permanent duty post on the Qinghai-Xizang Railway. Since 2006, when the entire Qinghai-Xizang Railway was put into operation, batches of service members arrived here, watching over the tunnel and safeguarding the trains that journey through the snow-covered mountains. The mountains here rise so high that, sometimes, even home feels beyond their sight. They carry their longing through the wind and snow, keeping countless families safe with their dedication and unwavering loyalty.
