XI'AN, Oct. 1 (Xinhua) -- A scenic moat area along the city wall in northwest China's Xi'an, capital of Shaanxi Province, opened to the public for free on Thursday after renovation.
The 14.6-km-long moat is an artificial water barrier surrounding the 13.7-km-long wall of the city, a well-preserved structure built during the early Ming Dynasty (1368-1644) and used as a fortification for military defense.
