There is a magnificent view of the desert smoke falling in the ancient poems.

Analysis: "The desert is lonely and straight, and the long river falls in yen." This is a famous sentence by Wang Wei, a great poet in the Tang Dynasty. People used vivid pen and ink to describe the strange and magnificent scenery outside the Great Wall. "The desert is lonely and straight, and the long river sets the yen", with vigorous brushwork, bold artistic conception and broad vision, is praised by Wang Guowei as a famous sentence of "the wonders of the ages". The title of this poem is "Make it a fortress", and the whole poem has eight sentences: "If you want to ride a bicycle and ask for directions, you belong to the country and have a long life. Sweat on the bill, and the goose will return to Hu Tian. The vast desert is lonely, and the Yellow River sets the yen. Xiaoguan rides every time and 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. It is mentioned in the poem that he met the reconnaissance cavalry in Xiaoguan, which is near Guyuan County, Ningxia (southeast of the county, north of Guyuan County, now Liwangbao in Haiyuan County), indicating that Wang Wei has indeed been to Ningxia. 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. Only the word 10 vividly describes the magnificent scenery beyond the Great Wall.
