Wang Difei is an author about whom limited public information is available. The library currently holds only one of his works, Unwanju Shici Sanji (Third Collection of Poems and Ci from the Unwanju Studio), commonly classified as modern poetry. Judging from the title, "Unwanju" may be the name of his study, while "shici sanji" suggests a collection of both shi and ci that has reached a third volume, indicating sustained writing over time. Since his dates of birth and death, nationality, education, official positions, and specific experiences are not clearly recorded, his biography is difficult to outline, and any assessment must center on his work. On the available evidence, Wang Difei draws on traditional poetic forms, and his classification under modern poetry suggests that he continues classical metrical and lyrical traditions in a contemporary context, with themes often involving personal reflection and everyday verse. Readers may regard him as a contemporary author known for writing in the old-style shi and ci forms, whose work offers some reference for understanding the current state of traditional-style poetry writing.
