One or two sentences in the poem were written from a distance, describing what the poet saw and felt when he looked at the horizon. People often say that the sunset is the end of the world, but "I" can see the end of the world. The sunset is visible, but my hometown is invisible. My hometown is far from the end of the world. The poet tried to describe the remoteness of his hometown. The poet's unusual feeling of spatial distance is beyond common sense, but it is also reasonable.
There are three or four sentences in the poem written in ink from nearby places, which describe what the poet saw and felt when he stared at Bishan. The third sentence is a link between the preceding and the following, which not only supplements the reason of "not seeing home", but also supplements the reason of "sneaking through the old warehouse", emphasizing the distance between the first two sentences and the space barrier. Hometown is invisible, not only because of the distance, but also because of the road barrier. It's disappointing that my hometown is cut off by the blue mountains. In addition, Bishan is now shrouded in dusk clouds. The poet's vision is from far and near, from big to small, the color is from bright to dark, and the homesickness is getting stronger and stronger, so that it cannot be dispelled.
Qian Zhongshu said: "there are two ways to write poetry: first, although the horizon is far away, the person you want is farther away;" Second, although the characters in the dream are close, they are farther than the horizon. "This poem belongs to the first way of writing. The poet's writing space is far away, and the sight of his hometown is blocked by the clouds of blue mountains and dusk, which gives people the feeling that his hometown is out of reach, highlights the helplessness and pain of the poet when he returns to his hometown, and expresses his sincere and deep yearning for his hometown.
