This sentence comes from Li Bai's "Shu Dao Nan".
Hey, hey, it's dangerous! The difficulty of Shu Dao is difficult to go to the sky!
Until the two rulers of this area forced their way through in the foggy age!
Forty-eight thousand years have passed. Don't talk to Qin Sai.
And Dabaishan, to the west, still has only one bird path, all the way to the peak of Emei.
Once it was broken by an earthquake, some brave people lost it, and then the ladder stone pile was hooked.
It means: Shu Dao is really difficult to climb, even more difficult than climbing to heaven. How far away is the legend of Can Cong, the first emperor of Shu, and Yufu! After about 48 thousand years, Qin and I didn't communicate. On the west side of Chang 'an, there is a tall and majestic Taibai Mountain blocking the road into Shu, and only the path that birds can cross can leap over the peak of Emei Mountain. The five strong men of Shu were crushed to death by landslides, and the ladder plank road connected Qin and Shu.
Poetry appreciation
On the basis of traditional themes, Li Bai, with rich imagination, focuses on describing the wonderful and breathtaking mountains and rivers on the road of Qin and Shu, and reveals some worries and worries about the social situation. The whole poem consists of 47 sentences, which roughly describes the difficulty of entering Shu according to the clues from ancient times to the present, from Qin to Shu.
There are five exclamations at the beginning of the poem, which is extremely difficult to say. Then wrote in detail that since ancient times, Qin and Shu have been the barriers between mountains. From Qin to Shu, Taibai Peak bears the brunt, and only birds flying high can fly low. The mountain is so high that it is difficult for even the sun god to pass. At the foot of the mountain, it is a winding river. At this point, pedestrians can only sigh. At this time, sad birds and trees, children crying at night, increased the loneliness and fear of pedestrians.
