In the ten mountains you saw in Tengchong, Yunnan, at least nine mountains have no heads, all of which are dormant volcanoes. The Tengchong volcanic geological park is one of the four major volcanoes in China with 97 volcanic volcanoes. Early in the volcanic park, the village in the distance is still covered in mist, mysterious and beautiful, and when we take the hot air balloon, the distant mountains are covered in a mist. This is the morning time, then look down to the crater clearly.
