Generally speaking, a poetry genre is usually an agreement or classification of the theme, style or literary characteristics of a poem on a broad level. Some critics believe that genre is the natural form of literature, while others believe that genre research studies how different works relate to and quote other works.
Modern poetry debate:
Traditional poetry attaches great importance to the form of poetry, and the use and development of form is basically to reflect the aesthetic feeling of poetry, which is conducive to reciting and making the content more profound. In modern poetry, however, the format is relaxed, and generally at least branches and rhymes are kept, or only branches are left.
Some branches of "poetry" may be just prose after removing the branches. Poetry that completely ignores the format is actually difficult to identify as poetry. Of course, this involves the definition of poetry and its development.
