Shu Road crosses Qinling Daba Mountain, with high mountains and deep valleys, rugged roads and impassability. Li Bai, a poet, once wrote a poem "Difficult Road to Shu", which is said to be difficult. Usually, the "Shu Dao" mentioned in academic research refers to the rest road, meridian road, old road and Luoluo Road (Tangguang Road) from Guanzhong to Hanzhong, as well as Jinniu Road and Micang Road from Hanzhong to Shuzhong.

detailed description

Shu Dao in a broad sense is the general name of the road between Guanzhong and Sichuan Basin. During the Qin and Han Dynasties, after thousands of years of development, four of them passed through Qinling Mountains and four passed through Bashan Mountains, forming eight ancient traffic arteries crossing Sichuan and Shaanxi. Jinniu Road is the earliest and most important of Bashan No.4 Road. According to Records of the King of Shu, Qin wanted to attack Shu, and in the name of offering a golden bull and a beautiful woman, he tricked Shu into opening the way. With the opening of the road to Shu, Shu ushered in the fate of national subjugation.

In a narrow sense, Shu Road refers to the postal road in Sichuan, which starts from Chengdu in the south, crosses Jianshan Mountain in size and reaches Guangyuan in the north. In Li Bai's poem, "an earthquake breaks the death of the brave, and then the stairs and stones overlap" is also the Taurus road. At present, many sections of national highway G 108 overlap with Jinniu Road, and the Sichuan section of Xicheng high-speed railway, which will be opened soon, almost runs through mountains and mountains in the same direction.
