Liu Tiren is an author in Chinese classical literature about whom relatively little biographical information is available. Two works can currently be confirmed as his: Qisongtang Ciyi and Yici Lu, both commonly classified under classical poetry and canonical works. Qisongtang Ciyi is a work of ci poetics, discussing the composition of ci, the styles of ci writers, and the appreciation of ci works, reflecting the traditional literati's understanding and evaluation of this genre. Yici Lu belongs to the category of notes and miscellany, covering observations, miscellaneous records, and literary anecdotes, and may serve as a reference for understanding the tradition of classical notes. Because public information is limited, Liu Tiren's native place, dates of birth and death, official career, and social connections cannot be reliably established, and the outline of his life remains unclear. The two extant works present his writings from the directions of ci poetics and miscellaneous notes, helping readers understand the intellectual interests and writing practices of classical literati and offering some reference value for the study of classical poetry and note literature.
