Human history in Daba mountain area

Daba Mountain, separated from Sichuan and Shaanxi provinces, controls the lower reaches of Hanshui River and the middle reaches of Yangtze River, which has important military value. In the East, today's Zhushan and Fangxian areas in Hubei Province were once the places where Qin Chu fought and Han and Wei fought. The Ming and Qing Dynasties were the places where refugees took refuge and lived, and also the places where peasant rebels were active. Li Zicheng, Zhang, and other rebels have been fighting loyalists here for a long time. During the Agrarian Revolutionary War, the Red Fourth Front Army smashed the three-way siege and the six-way siege of the Kuomintang Sichuan warlords in Tongjiang, Nanjiang and Bazhong, and established the Sichuan-Shaanxi base area. Gu Mi Cang Road is the only way from Hanzhong to Northeast Sichuan and Bazhong. 1932, the Red Fourth Front Army and the China People's Liberation Army 18 Corps entered Sichuan from Shaanxi, all along this road.
