Baoxie Road, starting from Baocheng in Hanzhong in the south and ending in Xieyuguan in Guanzhong in the north, was the main passage connecting Guanzhong and Hanzhong in ancient times. It is an ancient plank road with the earliest excavation and the largest scale in the history of our country. Since the Warring States period, some people have chiseled stone frames and built plank roads in the valley. Successive dynasties have added and repaired it many times, and later generations named it "Baoxie Road". From the end of the Han Dynasty to the Five Dynasties, military struggles between the north and the south all took the route of Baoxie. In the struggle between Chu and Han, Liu Bang adopted Han Xin's strategy. The "plank road" in "Mingjian Road, and secretly crossing Chencang" refers to this; during Emperor Wu of the Han Dynasty, tens of thousands of people were sent to repair the Baoxie waterway, but failed to make water transportation possible; during the Three Kingdoms period, Zhuge Liang The fifth Northern Expedition came out of the Qinling Mountains from this point, and the troops were divided to garrison fields in Xieshui. The total length of Baoxie Road is 470 kilometers. The southern end of the plank road is called Xiaoshimen, and the northern end is called Dashimen. Emperor Wu of the Han Dynasty added 250 kilometers of paving slopes, and thus there was a grand occasion of "the plank road is thousands of miles away, and everything is accessible". At that time, iron or gunpowder was not used to excavate rocks, but the original method of "burning fire and stimulating water". On the inner wall of the tunnel and on the cliffs on both sides of the Nanbao River in Shimen, there are nominations and poems left by officials and literati since the Han and Wei dynasties, commonly known as "Shimen Stone Carvings". In 1971, the Shimen Reservoir was built, and 170,000 square meters of major stone carvings were moved to the ancient Han Terrace for preservation.
