Diaochong Notes of Poetry is Mr. LIU Yan-wen’s representative work of poetry and prose appreciation. It is an evaluation work that focuses on creation, inheriting and promoting the concept of literature of nature and spirit, with a focus on the discussion of craftsmanship, and emphasizing the perfection of the work’s craftsmanship over originality, which is completely different from the mainstream of classical literature research since modern times. The discussion of the technical gains and losses of specific works in the book reflects LIU’s special insights. Although there is still room for discussion in LIU’s views, in the current era of rapid progress in AIGC, LIU’s meticulous technical research can restore the creative mechanism of traditional Chinese poetry and prose, and be used as an auxiliary technology. It is worth carefully studying and promoting.
