Physical Geography of China 

Our country is the one with abundant resources and vast territory. There are unique natural resources and geographical wonders on the earth in a vast world of 9.6 million square kilometers. In addition to the beauty and magnificence, the unpredictable nature has left many difficulties for mankind to solve. Do you know where the real source of the Yangtze River is? Do you know that Mount Everest is getting lower? Do you know why the thousand-year old well "open its eye once sees money"? Do you know if Cordyceps is an animal or a plant?… These natural mysteries full of psychedelic colors are difficult to interpret simply by modern civilization. They are like a magical codebook, waiting for humans to explore and grope.
