Zhagana, Gannan, is known as the tears of paradise. Zhagan is a natural stone city, located in an ancient city in Diebu County, Gannan Tibetan Autonomous Prefecture, Gansu Province, which means "stone dumplings" in Tibetan. The terrain is like a giant palace on a grand scale and a natural rock wall. Zhagana Mountain is a wonderful, cloudy and fairyland. The reasonable combination and complementary integration of nomadic, agricultural, hunting and harvesting activities in the Tibetan village has become a model for harmonious coexistence between people and nature.
