In the year, January is the coldest day in Hoh Xil, and at the end of the day's work, reporters shivered into the down sleeping bags one after another, and in just a few minutes, their bodies were quickly wrapped in warmth, and everyone praised technology for making life better.
But we soon realized that since our heads couldn't fit fully into our sleeping bags, our heads seemed to be in the freezer, getting colder and colder, even though every breath of air that could be exhaled inside the Sonam Dajie Conservation Station condensed into a thick white mist.
