Early spring in Tibet East is the blossoming season of peach, the airport we arrived is at 4,300m above sea level, cold night and high altitude makes you feel very uncomfortable in the first few days. Foreign people are hard to understand why Tibetan are so happy even living in such tough environment, it is only because of their religion. There are 6 summits above 8,000m, 50 summits above 7,000m and Innumerable peaks above 6,000m, the traveling altitude is about 3,000m to 5,000m.
