The purpose of writing this book is to "select and record erotic songs", that is, to mainly collect the feelings of both men and women. From the extensive content, it is not as good as the Selected Works, which was written earlier. However, compared with Selected Works based on literature, it also has its own characteristics. For example, in the selection of temple poems that praise and praise, it is not as good as Selected Works. Those who carefully select every article and understand the language, but abandon the abstruse classics, such as Hanshu Nursery Rhyme Record and Huijindi Nursery Rhyme Record, all belong to this category. They also pay more attention to folk literature, such as China's ancient long narrative poem Peacock Flying Southeast, which is the first time to see this book. It attached great importance to the five-character and four-sentence short songs that appeared in the Southern Dynasties, and collected as many as one volume, which played a certain role in promoting the development of the poetic style of five-character quatrains in the Tang Dynasty. It doesn't record the works of living figures like anthology, but selects the works of many poets after the middle period of Liang Dynasty. These poems pay more attention to rhythm and antithesis than "Yongming Style", and we can clearly see the mature process of "Modern Style Poetry". Shen Yue's eight poems and other miscellaneous poems are included in the book, from which we can learn about the integration of poems and poems in the late Southern Dynasty and the formation of Song Style in Sui and Tang Dynasties. There are some selected poems in Ode to Yutai, which can be verified or lost. For example, Cao Zhi's "Abandoned Wife" and Yu Xin's "Qixi Poetry" are all missing from their collections, and the works of women writers such as Ban Jieyu, Bao and Liu Lingxian are also preserved and circulated by this book.
