According to the historical background, what are the main literary creations before and after the liberation of Korea?

In the late 1930s, Japanese imperialism stepped up its rule over Korea in all aspects, making it difficult for progressive writers to make public activities. Only the revolutionary literature and art, such as poetry, novels, drama and political comments, which were produced and developed in the anti-Japanese armed struggle led by Kim Il Sung, left a glorious page in the history of modern Korean literature. Among them, Blood Sea (1936) and Flower Girl (1930) are all famous dramas. 1945, after the end of World War II, the Korean people also ushered in their own liberation. But a few years later, North Korea and South Korea established two countries respectively, so the modern literature of North Korea actually became the modern literature of North Korea and South Korea. For more than 40 years after the liberation of Korea, both during the War of Liberation against America and during the post-war recovery and socialist construction, new and old writers created together, pushing modern literature to a new stage of prosperity and development. North Korea's famous works include: Baitoushan (1913-1951) and Park Seyong (1902-). Li Qiyong's novel Land (Volume 1-2, Volume 1948- 1960) and Qian Shifeng's novel River Flowing (Volume 19 15) are described. Jian Huang's short story The Burning Island (1952), Qian Shifeng's novella The Fighting Villagers (1953) and Shi Runji's novel The Birth of the Times (1964) describe the liberation war of the motherland. Li Buk Myong (1908-)' s novella A Laborer (1947), Quan (1925-) and Zhao Bailing (19 1925-)' s short story Hundred Flowers Yin Shizhong's novel Senior High School Entrance Examination (1963) and Li Genrong's novella The First Harvest (1909) and so on. These works all express the author's understanding and feelings about socialist reality from different aspects.
