| After the 1990 s,with the continuous progress of globalization,large-scale migration has occurred in the world.As a global cultural phenomenon,diaspora has attracted the attention of post-colonial researchers.Under the background of the complicated and changeable world situation,the context of using the word "diaspora" also expands with the change of economic and political factors,from the original reference to the experience of Jews being forced to live away from their homeland,to describe the situation of people belonging to one people with the same culture scattered around the world.In the 20 th century,Taiwan became an important place in Chinese history as a discrete place where many people from other provinces crossed the sea to here.Since the Kuomintang regime was forced to move to Taiwan in 1949,the two sides of the strait have been separated for a long time,and the fate of the two million soldiers and civilians who were moved with the army has changed accordingly.During the decades of their lives in Taiwan,many intellectuals have written about their past experiences in various forms,such as autobiographies,memoirs or novels based on their own experiences.This article starts from the discrete situation of the contemporary authors who moved to Taiwan,and takes the autobiographical writing in their works as the research text,retraces the path of their lives,and analyzes the discrete themes from the three dimensions of identity dispersion,imagination of the original homeland and national identity,in order to explore their mental journey in the process of recording their life experiences,taking this as a view of a generation or even a section of Chinese history,and to re-examine the spiritual connotation of their conscious identity and homeland identity.The introduction part expounds the reason of choosing the topic and the research value and significance of the topic,combs the related research situation at home and abroad,and defines the three important concepts,that is,authors who moved to Taiwan,autobiographical writing,discrete themes.The main text is divided into five chapters.The first chapter clarifies the relationship between the autobiographical writing and the discrete theme,starting with an overview of the creation of autobiographical writing by authors who moved to Taiwan,analyzing the background and significance of their creation,and then explaining the operation principle of discretization as a generative mechanism for autobiographical writing.The second chapter,from the perspective of individualization,explores the identity and discrete experience of the writers in terms of individual,national and cultural.The third chapter discusses the homesickness writing of authors who moved to Taiwan in the process of their dispersal,and uses the homecoming mode in Lu Xun’s novels to organize the logical framework in the form of leaving-returning-departing again,ultimately forming the localized concept of my peace of mind is my hometown.The fourth chapter presents the collective character of the discrete theme at the national level,using the collective memory of authors who moved to Taiwan during the war period to construct a national and literary community of discrete groups,and then retracing and reflecting on history.The fifth chapter discusses the aesthetic features and cultural values of the discrete themes,and analyzes the narrative techniques and typical images of the autobiographical texts of authors who moved to Taiwan,and then excavates the inherent aesthetic and realistic cultural value contained in it. |
