Chin's Great Wall, which dates back to the country's Ming Dynasty, was covered in a sea of clouds after rainfall in the city of Shuozhou in northern China's Shanxi Province. 

This Great Wall was built over 600 years ago. It's as long as 20 kilometers and about half of it has remained relatively complete. 

It has rarely received any restoration and is of high value for military and historic study. Its unique beauty is also liked by many tourists.
