With hypoxia at the high altitude and walking difficulty in thick snow, these porters have to endure tiredness and burden for every step. Exhausted, they still were reluctant to have the bottled mineral water but just sat down to eat snow. They walked for 3 hours at a distance of 1.6 kilometers, and finally sent the supplies to their comrades-in-arms at the station. "It was worth it to endure hardship and difficulties as long as the supplies could be delivered earlier to our comrades-in-arms on the mountain!"
