Poetry is a literary genre with concise words, jumping structure, rich rhythm and rhyme, which highly reflects life and expresses thoughts and feelings. Jumping is one of its basic characteristics. The jumps in poetry are mostly composed of two or more images. There is no continuity between the images and they are only maintained by an emotional clue. It uses discontinuities to express coherence, and uses parts to summarize the whole, leaving a broad field for readers to imagine. For example, "Snow on the River": Birds in thousands of mountains have disappeared, and all traces of people have disappeared. A man with a coir raincoat in a lone boat, fishing alone in the snow in the cold river. Liu Zongyuan's landscape poems have a distinctive feature, that is, the objective realm is relatively secluded, while the poet's subjective mood appears relatively lonely, and sometimes even too lonely, too deserted, without any human atmosphere. This song "Snow on the River" is exactly like this. The poet only used twenty words to describe a quiet and cold picture: On the river covered with heavy snow, there is a small boat and an old fisherman, alone in the middle of the cold river. fishing.
