Shaanxi, formerly romanized as Shensi, is a province of the People's Republic of China. Officially part of the Northwest China region, it lies in central China, bordering the provinces of Shanxi (NE, E), Henan (E), Hubei (SE), Chongqing (S), Sichuan (SW), Gansu (W), Ningxia (NW), and Inner Mongolia (N). It covers an area of over 205,000 km2 (79,151 sq mi) with about 37 million people. Xi'an—which includes the sites of the former Chinese capitals Fenghao and Chang'an—is the provincial capital. Xianyang, which served as the Qin capital, is located nearby. The other prefecture-level cities into which the province is divided are Ankang, Baoji, Hanzhong, Shangluo, Tongchuan, Weinan, Yan'an and Yulin.Shaanxi comprises the Wei Valley and much of the surrounding fertile Loess Plateau, stretching from the Qin Mountains and Shannan in the south to the Ordos Desert in the north. Along with areas of adjacent Shanxi and Henan, it formed the cradle of Chinese civilization, with its Guanzhong region sheltering the capitals of the Zhou, Qin, Han, Jin, Sui, and Tang dynasties. It does not include the full territory of the Yellow River's Ordos Loop, with the Great Wall of China separating it from the grasslands and deserts of Inner Mongolia.
