What is the meaning of rain in classical poetry? Urgent need!

Mei: "Scattered into mud, ground into dust, only fragrant and solid" (showing the unyielding nature of human beings) Liu: "Why should the flute be wronged by the willow, which is not enough to close the door" (showing the corruption of imperial politics) Grass: "Spring comes and grass grows" (indicating that the purpose will be achieved in due course) Rain: "Young people listen to the rain on the balcony, and red candles faint their accounts." Only show the scenes of one place, and the heart of a teenager will always be bohemian. When they were young, they didn't know the taste of sadness. Even listening to the rain, you should find a romantic place and choose someone you like to stay with you. At that time, they were carefree, had no life experience, and had lofty aspirations in their hearts. Even if they are sad, they just look elegant and carefree. They just say that they are worried about adding new words. In leisure and pride, I will sigh for the sake of spring flowers and autumn moon: youth is a book that is too hasty. "In the prime of life, listening to the rain on the boat, Jiang Kuoyun's low-cut geese are called the west wind." A picture of sitting on a passenger ship listening to the rain, a picture of autumn rain on the river with vast waters and low winds and clouds. And a flock of geese flying alone. It just appears as the shadow of the author himself. After the prime of life, when the war is raging, poets often wander alone on the vast land of life, often wandering around and wandering around. He only showed such a picture of a spring rain, but it already contained all kinds of regrets and sad feelings. "Now I'm listening to monk Yu, and the stars are already on my temples." It depicts a self-portrait showing his present situation. A white-haired old man listened to the rain at night alone under a monk's house. The bleak situation and gloomy mood can be seen in more than a dozen words. Jiangshan changed hands, the sadness and resentment in the prime of life, and the joy of childhood were all blown away like wind and rain. Here and now, when I hear that little raindrop again, I am indifferent. "The joys and sorrows are always ruthless, and the next step is to drop water until dawn." Express the poet's helpless mood and let his "listening to the rain" come to an abrupt end. Jie Jiang's first poem contains a wide range of contents and deep feelings. Taking his life experience as the main line, he listened to the rain of the juvenile Song building and the rain of the mature passenger ship, writing about the monk's residence and the stars on the temple. The last two sentences transcend this apex and show a new emotional realm. The word "next semester" expresses the mood of people who listen to the rain. This kind of mood reveals the deepening pain of indifference and rejection, which can be described as a close call. Although "drop by drop until dawn", it is difficult to hide the anxiety of those who listen to the rain. Being in a monk's house, you can't really be isolated from the world, and you can't really forget life. "Drip till dawn" is also sleepless until dawn, not quiet until dawn. Clear hierarchy and clear context is another major feature of this word. In the first movie, I felt sorry for the past years, and in the second movie, I lamented the status quo. In chronological order, the middle-aged Song Lou wrote that the ship was in its prime, and then wrote that he was "on the side of the stars" in his later years, with "listening to the rain" as the clue, consistently.
