In the vast desert, a wisp of solitary smoke on the beacon tower goes straight into the sky; The long river is like a belt, and the setting sun is extremely round. These two poems highlight the roughness and strength of the desert and condense the poet's mentality. Judging from the wording of the poem, the language is not surprised and unpretentious, but it can describe the unspeakable scene in front of us, with endless implication, reaching the realm of muddy success and showing the profound skill of the poet.
The words "long smoke, sunset and lonely city" outline a magnificent night scene of the frontier fortress. Standing on the top of the mountain, looking around, the Gobi stretches for thousands of miles, and the steaming water vapor in the desert, like smoke and fog, is drifting away. It is sunset, only isolated cities are embedded in the barren desert, and the imprisoned cities vaguely reveal the soldiers' inner helplessness.
An endless breath comes to us, which makes people feel a strong shock, a quiet and sad pain of defending the north.
