Yangpingguan (simplified Chinese: 阳平关; traditional Chinese: 陽平關; pinyin: yángpíngguān) is a township in central Ningqiang County of Hanzhong Municipality in Shaanxi Province, China. The township is 116 square kilometers and has 20 villages and a population of 26,000.[1] The town is located 27.3 km from the county seat near the trisection point of Shaanxi, Sichuan and Gansu Province, in the upper Jialing River Valley. Yangpingguan, or Yangping Pass, is named after the pass between the Qin Mountains to the north and the Daba Mountains to the south, which has traditionally been the main entry point into the Sichuan Basin from the north.[2] The ancient Sichuan Trail passed through the town. The Baoji–Chengdu and Yangpingguan–Ankang Railways intersect at Yangpingguan.
During the Three Kingdoms period, a number of military engagements were waged in and around Yangpingguan, including the Cao Cao's conquest of Zhang Lu in the Battle of Yangping, Liu Bei's Hanzhong Campaign and the Battle of Mount Dingjun at the nearby Dingjun Mountain.
