This paper examines the novel Motherland and Compatriots written by Li Rong- Chun, through focusing on two aspects: identity editing, and views of war. In the viewpoint of "identity editing," this novel depicts how Taiwanese struggled in the dilemma between personal identity and their own goal in the war period. Based on different considerations, each of the characters in this novel "selected", "deleted", "rearranged" what they needed or disliked, and they displayed the most suitable looks for their own; this shows the complexity of "identification." Furthermore, in the viewpoint of war literature, Li Rong-Chun seldom mentioned about the fights on the war field but he profoundly and carefully depicted the status of China society and the intentions of why Japanese wanted to provoke the war. Besides, Li Rong-Chun also described about the diversity of identities and the embarrassing situations of Taiwanese during World War II; and these sufficiently show the conception of "identity editing." On the other hand, Li Rong-Chun not only showed the attitude for anti-Japanese war, but also specifically analyzed the relationship between war and imperialism from the view of left wing. This made the novel stand out from the works in the same period. Therefore, through rereading Li Rong-Chun and his work "Motherland and Compatriots," this novel left its irreplaceable value in Cross-strait literature and establishes its grand image in the history of the development of Taiwan Literature.
