    Autumn in Tibet is very beautiful because there are many fresh and bright colours everywhere.

    In north Tibet, one can travel several hundred kilometres by car and cannot see even a person. No one can be found in the north of Shuanghu-only treeless fields and grasslands. Warm autumn days bring life to all of nature. Wild animals become active, and Tibetan antelopes like to play near the lakes. When they run, sometimes they can reach 80 km an hour, leaving the hungry wolves far behind.

    Autumn in south Tibet is very different from that in north Tibet. Mount Qomolangma in southwest Tibet, the highest mountain on Earth, is world-famous for its beauty. It is over 8, 000metres high. There are over 2,300 kinds of plants and about 300 different kinds of wild animals on Mount Qomolangma.
