The site is located in Taiwen Village, Jianzhong Town, Weng'an County. The mountain terrain is precipitous, stretching for more than ten li in all directions. Centered on Yuhua Mountain, it is flanked by Gaobaixi, Changan Camp, Toupo Camp and Erpo Camp, with the Yangen River, Wudao River and Sangyan River forming the outer defence line.
In particular, the main peak of Yuhua Mountain is surrounded by sheer cliffs on three sides, with only a steep mountain path from Daping Mountain leading to the summit. It is a naturally endowed military stronghold.
