|Lee Ju-hong is one of major writers representing history of Korean children`s literature. He highly contributed to establishment of realism of children`s literature which might be a historical character of Korean children`s literature-he had ever acted in KAPF in the Japanese ruling period.His representative works have been listed on collection for Korean children`s literature published by famed publishing company. And his main literary collections are widely read in the book form even today. Although he had a career as a member of KAPF which had been considered taboo for long time, he is the only person who is assessed as writer of canon. Most of studies on his works have two key words of ``reality`` and ``pleasure``. When considering situation of Korean children`s literature that in most of the works, by emphasizing ``reality``, ``pleasure`` disappeared, while, by emphasizing ``pleasure``, ``reality`` disappeared, his literary world with both ``reality`` and ``pleasure`` takes a unique position.This study investigated his literary world to figure out such a unique aspect from historical context of ``genealogy of realism`` and ``genealogy of pleasure`` in Korean children`s literature. As a result, his juvenile novel showed ``tendency of Choi Seo-hae in children``s literature` where rich realistic description in experience style is distinguished while children`s song and fairy story showed ``tendency of describing in comic way producing laugh`` which was very rare in realism children`s literature.
