"Lonely smoke in the desert, the long river sets the yen" is a famous sentence written by Wang Guowei, who is close to you, describing the strange and magnificent scenery outside the frontier fortress after entering it. The picture is wide and the artistic conception is magnificent. The frontier desert is boundless, so the word "big" of "desert" is used. The frontier fortress is desolate and wonders. The smoke lit by 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 also shows its strength and perseverance. There are no mountains and trees in the desert, and the Yellow River flowing through it cannot express the poet's feelings unless a word "long" is used. Sunset, originally easy to give people a sentimental impression, uses the word "round" here, but it 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 blends his loneliness into the description of the vast natural scenery. The forty-eighth chapter of A Dream of Red Mansions said: "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 can be regarded as the superb artistic realm of these two poems.
