During the Three Kingdoms period, Zhuge Liang, the prime minister of Shu and Han Dynasties, built the road from Hande County to Xiaojianguan for 30 miles, and even the mountains were in danger. He chisels stones here and flies to Geliang Road.

With the passage of the brigade and the interruption of the two cliffs at Dajianshan Cliff, it became a military pass to build a stone against the cliff and set up a pavilion to guard it, called Jiange.

Since the Sui Dynasty, Shaanxi and Gansu have entered Shu, diverted from Meng Jian County to Niutoushan, passed Damocles and reached Jianmenguan. Zhanting Road from Xiao Jian to Dajianguan has been gradually abandoned, and the name of Jiange Road has changed from the abbreviation of Jiange Road to another name of Jianmenguan.
