Tibet is truly the roof of the world. It is the source of famous rivers like the Yangtze, Yellow, Mekong, and Indus; it is a Buddhist holy land, where you can see Tibetan Buddhist prayer flags hanging all around; it is a sacred place, where magnificent monasteries are sitting halfway down the snow-capped mountains, under the blue sky, or close to the pure lakes. More than 2 million foreign travelers every year. They come to this land and visit the iconic images like the prominent historical architectures - Potala Palace, mystical Jokhang Temple; go for adventure by bike riding on the way to Namtso or suburb of Lhasa City; go to see Mt. Everest – a trip to Everest Base Camp could be an unforgettable memory of your life.
