| Wu Yu’s Guanlin Poetry talks about Su Shi, Huang Tingjian, Wang Anshi, Chen Shidao and many other Northern Song Dynasty poets, with its special adoration on Su Shi. Focusing on the techniques of literary quotation and textual research, he records anecdotes of the world, and discusses ideas, rhythm, words, sentences, and other creative skills. The two aspects of “on poetry and events” and “on poetry and speech” have been considered. With regard to the main theme of poetry, Guanlin Poetry advocates taking ideas first, conforming to nature, laying stress on skills, and paying attention to the integrity and talent of poets. It prefers the poetics of using events, “exchanging bones”, provenance of words, and “taking vulgarity as elegance” in the Jiangxi poetic school. And it pays attention to textual research and errata, which provides valuable reference materials for the study of poetic theory in Song Dynasty.
