Prose is diverse and flexible. As Lao She said, writing down what we usually say is prose. Of course, literature encourages young people. As far as he is concerned, he has reached the realm of writing an article easily. But at least, prose is plain, and it is much easier to organize what we want to say into a coherent and prominent article than to write a poem. As far as its use is concerned, plain prose makes readers understand it at first sight, and is not limited by the number of words and sentences, so it is easy to express the content clearly. It is not as implicit as poetry, so from a practical point of view, prose should come before poetry. If the language is concise and profound from a literary point of view, it is poetry.
