These two poems fully embody the picturesque features of the poems and attach great importance to the picture sense of the scenery. First of all, it has a picturesque composition, from the sunset in the sky to the beacon smoke in the air to the underground river, from the nearby beacon smoke to the distant sunset to the endless desert. Although there are not many scenery on the screen, the space is wide and the levels are rich. Second, it is like a painted line, with smoke and dust in the endless desert. Just use simple lines to outline the basic form of the scenery, which is very general, like an abstract work. Third, these two sentences are also very colorful. The vast desert is full of yellow sand, and the orange sunset at dusk converges its brilliance, living quietly in the sky and reflecting the calm river water into white light. A wisp of white smoke rises from the desert and goes straight into the sky, and the magnificent frontier scenery is as it is now.
The frontier desert is boundless, so the word "big" of "desert" is used. The frontier fortress is desolate and wonders. The smoke from the beacon tower is particularly eye-catching, so it is called "solitary smoke". A word "solitary" describes the monotony of the landscape, and a word "straight" behind it shows its strength and perseverance. In the desert, it is easy to give people a sentimental impression, but the word "circle" here gives people a feeling of warmth and boundless. The word "circle" and "straight" not only accurately describes the desert scene, but also shows the author's deep affection. The poet skillfully integrated his loneliness into the description of the vast natural scenery.
