Liu Mian is known from the single work in our collection, Wan Zhi Tang Ji (Collected Works of the Hall of Late Knowledge). Beyond this, public information is limited: his nationality, dates of birth and death, and life experiences cannot be confirmed. What can be learned about him comes mainly from this work, catalogued under classical poetry. The title "Wan Zhi Tang," literally "the Hall of Late Knowledge," suggests a studio name expressing the author's belated self-awareness and his wish to keep learning in later years. The collection presumably consists chiefly of traditional poetry, with themes such as personal reflection, everyday observations, and seasonal scenery. Lacking further documentary evidence, it is difficult to determine his poetic lineage or the circulation of his work; readers may turn directly to the text of Wan Zhi Tang Ji to sense the author's temperament and style.
