In Wenshan City, Yunnan Province, there is an altitude of nearly 3,000 meters high mountain - thin bamboo hill, the highest point of the southern tip of the Yunnan-Guizhou Plateau. It is located south of the Tropic of Cancer, humid climate, lush plants all year round murmur of streams, spring ding dong, red bamboo, birds fly ape crow. In the face of this beautiful subtropical scenery, who can think of here three hundred thousand years there has been twice as snow-capped, year-round ice-cold scene? Three hundred thousand years ago, here live in the green kingdom member Stegodon and many others Creatures, all buried by the frozen snow that year. Is this a myth? It has been proved by science that during the 300 million-year-long cycle in which the sun leads the galactic galactic movement of the nine planets, the heat radiation accepted by the Earth is unbalanced. During this period tens of millions of years of cold weather occur, territorially called
