Abstract: Along with the propagation, development of the study in Song poetry in Korea, Japan, the trend in the literary arena in foreign nations changed from worshipping Bai Juyi to admiring Du Fu. As a milestone monograph on poetics in the history of their respective nation, Po Xian Ji accepts the characteristics of refinement, traceless allusions from Du Fu, pursues the concept of exquisite poetics, just “like nature itself without any artificial polish”, whereas Jibei Notes on Poetry follows Du Fu’s overall aesthetic belief in synthesizing poetic inspirations, poetic forms, exploring the criteria for “the acme of perfection” based on that, evaluating Du Fu’s poems with “flexible law” at the same time. In comparison, even though both authors derived so much nutrients from Du Fu’s poems, Lee In-Lo adopted the attitude of a historian, summarized Du Fu’s poetic style from the standpoint of a poetry scholar of later generation, while Toraseki Ishiren produced a foreign monograph on poetry that addresses the poets in Tang, Song Dynasties from the perspective of an overseas critic. These differences occur due to the authors’ divergent vision in their writing, their creative concept, their region, their time as well

Key words: Du Fu, Po Xian Ji, Jibei Notes on Poetry, notes on poetry, parallel research
