Tibet, with its high and broad topography, uncertainly variable meteorology and shrouded mystery in its culture, has been showing the grandeur of "Roof of the World", and fascinating many people who love the nature. However, when you get close to it in warm sunlight, you will be excited to find that besides the snowfields and extending deserts, there are really bloomed meadow, luxuriant forest, swamps with cranes, and beautiful lichen on rocks and trees.

　　We shall be very grateful to professor Xu Fengxiang and vice-professor Zheng weilie .Their strenuous work with heart and soul present us a colorful world.
