Liupan Mountains
The Liupan Mountains are a mountain range in northwestern China, located mostly in southern Ningxia Hui Autonomous Region. The range marks the southwestern boundary of the Ordos Basin.
Its southern section is known as Mount Long, which strides southeast through eastern Gansu and western Shaanxi province before joining into the Qinling Mountains, giving rise to regional names like "Longxi", "Longdong" and "Longnan". It is the western boundary of the Guanzhong Plain, and is also the source of the Qian River, a left tributary of the Wei River that flows through the prefectural city of Baoji.
