In 1950, October, as China has participated in Korean War, there is movement of supporting Cho Sun and protecting family and nation against USA in China. 6 month later, RenMin RiBao has published authored by Wei Wei. It has been read a lot among the Chinese soldiers and Chinese. And also this book showed why China participated in Korean War. It’s because they want to make war hero to use the movement of changing an ideology when socialism built at the beginning. Documentary literature is treated as a kind of prose in China. It’s because documentary literatrue takes typical meaning or human life in real society and it is also for real politics with rapid expression through artistic device. Generally, the characters should be real person in documentary literature and keep original figurein realistic source. However as it has own limits such as fiction of source, illiberal of format, difference between work and realities and etc it is pointed them out as the problem. Due to this kind of limit of documentary literature, we can’t exclude the possibility of showing author’s intention for public interest and also it can provide the basis of logic for whole works and there can be political intention in the base as well. Therefore we can infer immanent political intention of Chinese leaders. But the created works made for a need of politics would lose original value and true identity.
