The original poem of joining the army:
There is a dark snow-capped mountain in Qinghai, with long white clouds and a lonely city looking at Yumenguan. Yellow sand wears golden armor in hundreds of battles, but the loulan is not returned.
By describing the vast battlefield scene and fierce fighting life outside the Great Wall, the heroic feelings of swearing to serve the country were expressed. The first two sentences use geographical names and magnificent images to outline the magnificent frontier fortress scenes far from the Great Wall, such as Qinghai, Changyun, Snow Mountain and Yumenguan. Among them, the words "darkness", "lonely city" and "overlooking" are used to point out the vast and desolate geographical features of the Great Wall, which makes it easy for people to feel a sense of sadness.
The third sentence is "yellow sand wears golden armor in hundreds of battles", and the language is extremely concise and vigorous. The harsh environment of desert sandstorm, the tragic experience of "winning every battle" and the hardships of "golden armor" not only depressed the hero's fighting spirit, but also strengthened his fighting spirit.
Therefore, the fourth sentence ends with the heroic oath of "Loulan will not be broken or returned", which seems natural and full of brilliance. This poem contrasts the true colors of heroes with the cold of the battlefield and the hardships of the expedition, which is vivid and vivid. It is one of the outstanding representatives of "the weather in the prosperous Tang Dynasty" to drive high-spirited and heroic feelings with the vast and magnificent scenery outside the Great Wall.
