During the snow season the nighttime temperature is -10oC. During the daytime sunlight reflecting off the snow is dazzlingly bright, yet working in the snow is cold enough to make hands and feet go numb and stiff, so a fire must be built at the work site where workers go every ten minutes or so to get warm and regain the feeling in their limbs so they can resume work.
雪季時，夜裡溫度是攝氏零下十度，白天陽光在白雪反射下卻又刺眼而酷熱難當，但別看太陽大，雪地工作還是凍得人手腳僵硬，只好在一旁生火，施工人員每隔十幾分鐘就回到火堆旁取暖，等凍僵的手腳恢復知覺，再繼續施工。
