Badain Jaran Desert is located in North China's Inner Mongolia. Mountains are formed through sand accumulation. The wind keeps blowing the fine sand away, continually eroding them.
The desert environment keeps most creatures away, but it is a perfect home for camels. After thousands of years of evolution, they are not only resistant to hunger and thirst, but also to high temperature and cold. In desert storms, they can even walk with their eyes closed.
About 4,000 years ago, Bactrian camels were domesticated. Since then, they have become mankind's most loyal partners in the desert.
