The two sentences mentioned by Du Fu in Shu Dao Nan are: jathyapple, the cuckoo's crow and the empty mountain. Zigui is a cuckoo, with the most places in Sichuan and a sad voice. If the cloud is "not as good as going home".

Selected paragraph:

We don't know whether this road to the west will never end. The road ahead is getting darker and darker. Nothing can be heard except the cries of birds surrounded by ancient forests. The male bird rotates smoothly and follows the female bird. Jathyapple, what comes to us is the melancholy voice of Du Fu, a sad empty mountain.

Translation:

Good friend, when will you return your westward journey? It's really difficult to climb this steep and dangerous road in Shu Road! I saw the sad bird whining on the old tree; Male and female birds are flying each other in the dense forest. On the moonlit night, I heard the sad cry of cuckoo, echoing in the empty mountain, which made people feel endless!

Poetry appreciation

The poet described the magnificent scenery of Qinling with unpredictable brushstrokes, and deliberately rendered the high risks and obstacles of Shu Road, which naturally caused anxiety about the sinister political situation.

"Although the watchtower is strong, one person keeps it, and ten thousand people cannot break it. If he is not loyal, but a wolf to his companion? " And other sentences predicted that the buffer region relied on dangerous rebellion and gave a serious warning to the rulers of the Tang Dynasty. In the early days of Tianbao, the poet was keenly aware of the danger of the separatist regime in the buffer region through the appearance of peace in the world at that time, which was commendable.
