The Black City site is the most complete and grandest site on the northern line of the ancient Silk Road, located in the town of Dalaihubu, Ejina Banner, Inner Mongolia. To be honest, I don't like the site, because it makes me feel sighed, surrounded by desolate, black city surrounded by desert, it is said that black city is called black water city, but where is the water? Protect the environment, here really understand the importance of environmental protection, people, love our own home!
