There are many forms of expression of poetry, which are constantly developing and creating since ancient times, and their application is also flexible, exaggerated, repetitive, overlapping, jumping and so on. It's hard to describe. However, all methods are inseparable from imagination. Rich imagination is not only a major feature of poetry, but also the most important form of expression of poetry. In poetry, there is also an important technique of expression, which is symbol.
Symbol simply means "symbolic meaning", but in modern poetry, symbol is the direct image of the soul and should be paid attention to. From a modern point of view, there are three main ways to shape poetic images: replacing things with things. Similar to analogy, but different. The difference lies in: analogy is generally compared, and comparison is concrete and visible; Metonymy is concrete on the one hand and abstract on the other, which bridges the gap between concrete and abstract, makes the image of poetry more vivid and prominent, and arouses readers' association. This is what Ai Qing said, "Put wings on your thoughts, put clothes on your feelings, color your voice, and let the dead solidify."
To shape the image of poetry, we should not only use the materials taken from perspective to describe the picture, but also use the materials obtained from the senses such as hearing and touch to reflect the image in many ways, so as to be vivid and novel. Jia Dao, a poet in the Tang Dynasty, rode on a donkey and sang "Birds by the pool stay in the trees, and monks push the door down on the moon", but he also thought that "monks knock on the door down on the moon" could be used. He couldn't decide whether to "push" or "knock", so he made a consultation with his hand. Unexpectedly, the donkey blocked a big official's way. This man is Han Yu, a great writer. When the guards led Jia Dao to the horse, Jia told the truth. Han hesitated for a long time and said it was better to knock at the door. Because there is a "knock" sound, there are one or two knocks on the door on the moonlit night in the mountains, which makes the scene "live" and makes the environment more silent. "Wuti" and "Zhong" beside Fengqiao Bridge are also the crowning touch of this poem. There is also the music description in Bai Juyi's Pipa, which is "like pouring pearls of all sizes into a plate of jade". It is very vivid and wonderful! Modern, such as Huang Helang's "Morning Song": "There is also a stubborn listening/wind, rain, waves/faint/dawn/morning bell of Lingquan Temple/like a gushing spring/distant response/faint knocking down/a few sparse stars/cock crowing/as if crossing the ocean/cock crowing/like the tide. This poem is also well written. Therefore, if we master the skills of creating images with sound, it will open up a broader field for poetry creation.
Whether metaphor, exaggeration or metonymy depends on the poet's keen observation of objective things, his own feelings, bold imagination and even fantasy. It can be said that neither romance nor reality is a poet without imagination (fantasy). For example, Li Bai, who is famous for his boldness, has rich imagination and magnificent poetic style, and Du Fu, who is famous for his realism, also wrote, "When did you suddenly see this house in front of you?" ("The Hut is Blown by Autumn Wind") and "She has a fragrant cloud and a foggy mist, and her jade shoulders are cold. When can we lie on the screen again and look at the bright light and stop crying? "(Moonlit Night) and so on.
