Its location is strategic, controlling a pass on the Qin Mountains between the Wei Valley and the upper Han River,or named Chia-ling River(Chia-ling ChiangJialing Jiang)]. Passing through Baoji is the ancient North Silk Road, the northernmost route of about 2600 kilometres in length, which connected the ancient Chinese capital of Xian to the West over the Wushao Ling Pass to Wuwei and emerging in Kashgar before linking to ancient Parthia. Thriving early in the Tang dynasty, it has roots to 2000 BC, but is now a large industrial center.
