According to B. R. Myers, the work of Cho Ki-chon in the late 1940s exemplifies particular traits of the early cult of personality of Kim Il-sung built upon Soviet Marxism–Leninism and bloc conformity. They were soon replaced by the Korean ethnic nationalism of writers like Han Sorya. While Cho's Kim Il-sung is a brilliant strategist who has masculine qualities like strength and intellect, in Han's works he embodies traditional Korean virtues of innocence and naivety having "mastered Marxism–Leninism with his heart, not his brain". The ethnically inspired style of Han would establish itself as the standard of propaganda over Cho's.
