First, use dynamic lining and static method. At the beginning of the article, I wrote about my loneliness in the study, but I wrote about the sound of dead leaves of lilac trees. Being able to hear such a slight voice shows that the author's environment was quiet and his mood was calm. This technique of resisting stillness with movement has many applications in poetry. For example, in Wang Ji's "If you are in Xi", "Cicada is quiet in the forest, and Yingong Mountain is more secluded." There is also Wang Wei's "Sitting Alone in Autumn Night", "Falling fruit in the rain, singing under the grass lamp." They all use a slight sound to set off the tranquility of the environment and the tranquility of the soul.
Secondly, use metaphor, parallelism and personification. "Loneliness is a few mouthfuls of fresh air for people to breathe" compares the lonely mood to air, which vividly shows the indispensable importance of loneliness.
