The development of novels has been a focus of literary discussions in Taiwan since the beginning of the new century. Previous studies have identified the trends of "new historical novels" and "post-loyalist novels" as a continuation of the tension between the post-colonial and post-modern identities at the end of the 20th century. This paper suggests that, in addition to "the colonized" and "the loyalist," "the immigrant," a perspective adopted by Chiang Hsiao-Yun in her trilogy Ordinary People of Republican China," could be another way to look at the Republican people in the new historical writing. The trilogy is a collection of three novels composed between 2011 and 2016: Together after a Hundred Years (2011), Tamarisk Baby (2013), and Red in All Four Seasons (2016). These novels document the lives of women born in the Republic of China from 1912 to 1949, most of whom grew up in Shanghai and moved away after 1949. This paper discusses the idea of "Republican China" in these novels and analyzes how it is different from the post-loyalist novels written by other second generation mainlander authors. The paper divides the discussions of Republican China into three parts: Shanghai residents in the Republican China, Minguo immigrants and Showa descendants in Taiwan, and the ROC people in the PRC, and argues that Chiang's novels reconstruct the history with the perspective of "Republican China" and contribute to the diversity of new historical writing.
