“War” is an essential clue for understanding modern East Asian society. The frontline of the battlefield and the rear society outside the battlefield are inseparable. The rear experience of wartime society covers social mobilization and daily life. The field of life is also related to the practice and effect of “ideological warfare.” The war intensified the modern evolution of border space, identity, or regional mobility among the East Asian masses and subject consciousness, reconfigured identity, and ideological activities. The formation of Taiwan’s social culture after the war must also look at the Second Sino-Japanese War and even the legacy of “wartime China” in which the National Government ruled Taiwan, including the interpretation of the movement of people, wartime experience, and memory politics. Given this, this article is based on the essays of Overseas Chinese female writer Huang Meizhi(黃美之, 1930-2014), who had life experience in China and Taiwan and was a political victim, exploring the cultural shift of “wartime China” and the growth trauma it caused and analyzing the intertextuality between the writer’s life memory and literary representation restate. That is, to trace the movement, dismantling, and reconstruction of the body/identity of writers with wartime experience outside Taiwan and how they interact with the social, civil war context of post-war Taiwan after coming to Taiwan to reveal diasporic writing and the subject construction of wartime China generation.
