The first is the preface. If it is a collection of personal poems, it is usually written by a celebrity in the field of poetry or a theorist with status, making a general comment on the book and guiding readers to read it. Secondly, poetry works are usually divided into several series, such as writing scenery together and writing inner feelings in one series. The third is the postscript, which is completed by the author himself, such as the understanding of poetry, the feeling of creation, and the purpose of publishing poetry collections.
