Will there be altitude sickness when I go to Golmud, Qinghai?

The first time you go, you will definitely have altitude sickness. There will be headache, dizziness, dry mouth and other symptoms, but as long as you get used to it for a week or so, you will be fine. Drink plenty of water at ordinary times to avoid strenuous exercise. The average minimum temperature in winter is below zero 10, so keep warm. The altitude of Golmud is 2780 meters, but if you go west, you will reach Tanggula, which is 4500 meters!
