Lee Chan revised 19 poems under the North Korean regime which he wrote before the liberation from Japanese imperialism. The fact that there are different aspects on revision over one poem attracts sufficient attention. This study examined the aspects of revision and its intention. The results are as follows. The revised poem of Lee Chan looked heavily influenced by external condition of the literary circle in North Korea in 1950s. The backgrounds include cultural language policy as a basis of literary circle in the postwar North Korea, removal of bourgeois aesthetics idea, popularization of liberal arts, exclusion of formalism and purification process. Though works were written in 1930s, they were pure lyrical poems which were under criticism. Thus, his revision looked as a preemptive measurement. Together with this, he needed a revision to show his coherent attitude at the front of literary policy in North Korea. But, as overall revision of contents was impossible, he did revise in vocabulary, disposition of stanza and rhetoric. Of course, it was a revision to conform with the literary policy but he showed a craftsmanship as a poet in the process of revision. He showed his sense of craftsman in his revision. Although he was a socialist poet in the KAPF circle, he created considerable amounts of lyrics, which looks closely related with his expression of craftsmanship.
