Korea writers who choose North Korea after emancipation is very important in the unification of North and South Korea. Especially the poet Baik-suk and Novelist Han-Sulya is very important because they spent so long years in North Korea and can not write freely. The poet Imhwa and Novelist Lee-taejun spent so short time in North Korea after escaping from South Korea. So, they are not important in contrast to Baik-Suk and Han-Sulya. The poet Lee-Yongak and the novelist Lee-Kiyoung spent all their life in North Korea aftner emancipation. they had no tension with North Korean state regime. They followed the polictics of government without tension and conflict. Considering these situations, Baik-Suk and Han-Sulya is very important in literary unification of South and North Korea. But there are so many problems in studying these writers in South Korean literary study scene. Now So many scholars who study the poem of Bai-Suk do not want to study the poems of North-Korea because they are the result of state control and censorship of North Korea government. So many scholars who study the work s of Han-Sulya interpret that his works that represent anti-japanese activity of Kim –Ilsung in Manchuria under the Japanese Empire is the result of personal cult. These kind of attitudes are originated from the consciousness of cold war. To know poet Baik-Suk, we should study all his poems from Japanese Empire period to North-Korea period. It is very ridiculous for scholar to select and study only poems produced in Japanese Empire period. To know novelist Han-Sulya, we should consider historical situation of his work’s production. His works that deal with anti-japanese movement of Kim-Ilsung was created to evoke the historical facts which is concealed from Japanese censorship. It is very different from the works of personal cult that is created from 1967 based on idea of Juche. To study the Korean writers who choose North Korea after emancipation is very important in the process of literary unification. It is very important for scholar to free from cold war consciousness.
