He Qifang, a modern poet and literary critic in China, once said: "Poetry is the literary style that most strongly reflects social life. It is full of rich imagination and feelings, and it is often expressed in a direct lyrical way. Moreover, in the degree of exquisiteness and harmony, especially in the distinct rhythm, its language and prose are different. " This definition summarizes several basic characteristics of poetry: first, it reflects life in a highly concentrated and general way; The second is lyrical expression, full of rich thoughts and feelings; Third, rich imagination, association and fantasy; Fourth, language has musical beauty.
