The author focuses on what he saw and felt on the way to Anxi. The chin couplet "The Han moon sheds tears over the countryside, and Husha wastes horses' hooves" describes the situation of traveling on a starry night. The bright moon that my family and I were used to seeing in Chang'an was now hanging alone in the desert, looking a little sad, as if weeping at people. It does not say that he sheds tears because he is homesick for the moon, but it says that the moon sheds tears for himself. And my homesickness was vividly visible in my words. This is also the personification of the bright moon, giving the inanimate moon a lively personality, and serving as a foil for the lonely man walking in the desert, making the scenery in the sky and the earth blend into one, corresponding from a distance, and uniquely sentimental. Marching in the night, the soft sand made it particularly difficult for the horse to ride. The word "horse's hoof waste" not only refers to the wear and tear on the horse's hoof, but also means that the sand is soft and makes it difficult to walk. This shows that the journey is difficult, but the author still forges ahead. Then, on the one hand, the chin couplet takes over the neck couplet and continues to describe the march. At the same time, it makes another turn and transitions from night to day: "Looking for the river, the sorrow is gone, crossing the moraine and feeling that the sky is low." The scene in this couplet is very realistic and magnificent. The previous sentence uses the allusion of Zhang Qian's mission to the Western Regions to find the source of the Yellow River, which means that he is almost going to the end of heaven and earth; when passing through the desert, he felt that the sky was particularly low. There are descriptions of the hardships of the journey, but more of them describe the novel and magnificent sights that have never been seen in the eyes of a person who has just arrived from the mainland to the northwest frontier with an expression of astonishment. It is saturated with the author's pursuit of fresh life and love for the frontier, and is full of sincere passion.
