Why is poetry the most emotional representative genre in literature and art?

Poetry is the most emotional representative genre in literature and art. Poetry expresses ambition, which is the ideological core of poetry, but emotion is its manifestation. The so-called "five emotions written as words", "emotion classics" and "writing for emotion" in Wen Xin Diao Long all talk about the role of emotion in poetry and writing. Emotion is equivalent to its soul in poetry, and compared with other factors, its influence on poetry is almost the first. China's first poetry collection, The Book of Songs, contains 305 poems, almost all of which are lyric poems. The occurrence and development of western poetry is somewhat different from that of China. First epic, then dramatic poetry, and finally lyric poetry. However, no matter what form it takes, one thing is the same as China's poems, that is, it is lyrical. Homer's epics Iliad and Odyssey are full of emotions, and although they have the romantic characteristics of objective idealism, their essence is the thought of saving the people.
