Longnan is not only the birthplace of Qin people, but also the core of China's ancient western history, Qiang and other ethnic activities. Qin Xianmin once founded the country by herding horses in Xiquanqiu (now Red River in Lixian County); From Emperor Gaozu Liu Bangbing sent troops to Hanzhong, to Emperor Guangwu of the Eastern Han Dynasty "decided to return to Sanqin" and "defected to Wang Longshu" after occupying Tianshui, taking Longnan as the way to pacify Bashu ... Military strategists have struggled for several generations. Zhu Gekongming, the prime minister of the Han Dynasty, made an immortal contribution in the Temple of Wuhou in Qishan Fort, Lixian County.
