This article investigates post-war biographies written after World War II, such as Taiwanese Contemporary Biographies (1947), Biographies of the Republic of China, Collection of Taiwanese Celebrities (1953), Biographies of Taiwanese Celebrities, and Biographies of the Southern Taiwan (1957). It discusses the contents about de-enslavement and the tendency of nationalization in these texts. For example, these biographies delete the history about the participation in Kominhokokai (皇民奉公會) eitenally. Instead, they described the patriotic events during the Japanese reign and the post-war phase. In addition, some characters with the experiences of the puppet regimes are also deleted from these texts, so there is a gap in post-war Taiwanese biographies. The instances of Xie Wen-da, Chen Xi-qing, and Wu Dun-li are the best illustration of the above phenomenon.Based on above issues, how to interpret existing Taiwanese biographies and how to value these Taiwanese are serious problems for the modern research of Taiwan history. Furthermore, the evaluation should not depend on Japanese or Chinese texts. We should have our own standpoint. Those Taiwanese working for the puppet regime during the Japanese reign should accept as much attention as those Taiwanese working for the government at Chongqing.
