Chengjiayu Village is located at Jinyuan District, Taiyuan City of Shanxi Province. It was built in Tang Dynasty with a history of 1,300 years. Chengjiayu was not only a residential village, but also a land of defense. Stones are the main building materials back then, and each family had their own tunnel. Few years ago, villagers started to move out and left this ancient place empty. (Photo/People's Daily Online)
