How to create the aesthetic feeling of language in poetry?

China's classical poetry was characterized by its direct sensory power from the beginning. When it comes to writing poetry, it must be "emotion moves in the middle and words are spoken", that is, seeing the external scenery move the heart and then expressing it with poetry. The author saw the external scenery, aroused the inner feelings, and then wrote poems. Therefore, people can't die. Xin Qiji has two words: "One pine and one bamboo are true friends, and one mountain bird and one mountain flower are good brothers." Every pine tree and bamboo is my friend, and a bird and a flower on the mountain are my brothers. People should have the heart to cherish and care for all things in the universe.
