The Shu road, which is difficult to get to the sky, really exists. It is located in Guangyuan, Sichuan, and it is also an important transportation hub. In Li Bai's poems, most people think that there is a plank road and the traffic is extremely inconvenient, but in fact, Sichuan, as an important medium connecting the central and western regions, has very convenient traffic and is an important transportation hub.
It is not difficult to see that the plank road is built on a precipice, which is particularly dangerous. At that time, Shu Dao was a very important passage, and many distances led to it. The sword gate of Shu Road is also a very dangerous place. At that time, the Shu Road was in the present Sichuan area, and there was another name in Sichuan area, namely Shu State, where Liu Bei made his capital at that time, so the culture of Sichuan was also very profound.
Shu Dao includes roads leading to ancient Shu in all directions, including waterways from the Three Gorges to rivers, Bodao in Yunnan and Yinping Road in Gansu. Today's Shu Dao has been circulating for so long, mainly because of its strangeness and danger. These plank roads were built bit by bit by ordinary people in history. Therefore, the people have played an important role in the historical development of China, and we should respect the achievements of the working people.
