Starting out in the east on the ban

Starting out in the east on the banks of the Yalu River in Liaoning Province, the Wall stretches westwards for 12,700 kilometers to Jiayuguan in the Gobi desert, thus known as the Ten Thousand Li Wall in China. The Wall climbs up and down, twists and turns along the ridges of the Yanshan and Yinshan Mountain Chains through five provinces--Liaoning, Hebei, Shanxi, Shaanxi, and Gansu--and two autonomous regions--Ningxia and Inner Mongolia, binding the northern China together.
