Literature is the reflection of social life, and all literary works reflect social life, which requires the centralized generalization of art, but poetry requires a higher degree of centralized generalization than other literary genres.
Second, lyrical expression is full of rich thoughts and feelings.
Poetry is very lyrical, and the works are saturated with rich and strong thoughts and feelings. China's traditional poetry theory attaches great importance to this feature.
Third, rich imagination, association and imagination.
Poetry should not only have rich thoughts and feelings, but also integrate thoughts and feelings with the life pictures depicted in the works, and infect readers through vivid and beautiful images. This requires rich imagination, bold association and fantasy, so as to break through the boundaries between things and me, time and space, and stimulate people's spiritual feelings and rich emotions to the maximum extent. Therefore, for poetry, imagination, association and fantasy are not only the combination and movement of images, but also the creation of images, the expansion of realm and the release of emotions. Without imagination, association and fantasy, there would be no poetry.
Fourth, the musical beauty of language.
Poetic language especially requires musicality, and musical beauty can enhance the expressive force and artistic appeal of works. The musical factors of poetic language include rhythm, tone, rhythm and so on. Poetry requires clear rhythm, harmonious tone, a certain sense of rhythm, beautiful and moving recitation and musical beauty.
