Let the desert in the castle smoke and the long river set the yen, which is a famous sentence in this poem. According to this sentence, describe the scene of this sentence.

As the sun sets, the desert along the Yellow River is golden, and a wisp of smoke comes out of the chimney.

The vast desert is lonely, and the Yellow River sets the yen.

This poem comes from the five-character poem "To the Frontier" written by the Tang Dynasty poet Wang Wei. The original poem is as follows:

Riding a bike to visit the border and passing through Juyan County.

Pengpeng also floated out of Korea, and the geese heading north also flew into the sky.

The vast desert is lonely, and the Yellow River sets the yen.

Xiao Guan rides it every time, and it is protected in Yanran.

Wang Wei was ordered by Emperor Xuanzong of the Tang Dynasty to leave the fortress to pay his respects and visit the military intelligence. The "Juyan" mentioned in the poem is in the northwest of Zhangye, Gansu Province. It is mentioned in the poem that he met a reconnaissance cavalry in Xiaoguan, which is near Guyuan County, Ningxia (southeast of the county, north of Guyuan County, now Liwangbao in Haiyuan County). Some scholars believe that Wang Wei probably started from Chang 'an, went to Guyuan first, then crossed the Yellow River in Haiyuan County, Ningxia, and went straight to Wuwei and Zhangye in Gansu. On the way, Wang Wei was intoxicated by the scene in front of him and happily began to write.

The author's mission takes place in spring. On the way, I saw a few lines of returning geese flying north. The poet makes a metaphor on the spot and describes the scenery appropriately and naturally. In particular, the link of "lonely smoke in the desert, long river setting the yen" describes the strange and magnificent scenery outside the Great Wall after entering the frontier fortress. The picture is open, the artistic conception is bold and the color is pure and almost transparent. Big sky, straight, long and warm. These words vividly describe the magnificent scenery beyond the Great Wall and the mind of the viewer, which the master Wang Guowei called "the wonders of the ages". Forty-eight chapters of a dream of red mansions: "The desert is lonely and straight, and the long river sets the yen." How straight do you want to smoke? The sun is naturally round. The word' straight' seems unreasonable, and the word' round' seems too vulgar. When I closed the book and remembered, I seemed to have seen this scene. You have to look for two more words of these two, but you can't find two words. The advantage of "this is" poetry is indescribable, but it is vivid when you want to leave; "It seems unreasonable, and it is reasonable to want to go." This passage also reveals the superb artistic realm of these two poems.
