In the early Han and Wei period, the historically famous Luogu Road passed through the Huangdouliang area of Foping Reserve, and Wei Wei competed many times to use the army. Tang Wude resumed Luogu Road for seven years, becoming the traffic button connecting Chang'an with Hanzhong and Chengdu. The Tang emperors Li Shi and Li Yan went to Hanzhong through this road to escape the war. When the Tang Dynasty, Huayang Town, close to the protected area, set up a county with a population of 5,000 households and more than 10,000 people.
