If the changing process of the Taiwanese literature and its research is one of the most prominent processes, then the works of Lai Ho and its researches will no doubt play a key role in this process. That is to say, the works of Lai Ho and its researches play a rather important role in the turning point of the whole process of the history of Taiwanese literature. Like the messages showed in the statement "Lai Ho: the Father of Taiwanese Modern Literature" which elementarily put forward by Wang Shi-Lang in the middle of 1930s and continued to be used in the Pacific-war period, and which were almost opposing to another statement "Colonial Literature" pronounced by the Japanese literary critics and writers living in Taiwan. When it came to the early period of post-world war 11, another efficacy was granted to the works of Lai Ho and its researches, such as the using of Yang Qui who pointed out the achievement of Japanese-ruling Taiwanese literature movement to the Mainlanders of literary circle now living in Taiwan. After some argument and dispute, from the middle of 1960s via Nativist literary debate to the early 1980s around, the statement "Lai Ho: the Father of Taiwanese Modern Literature" was pronounced and recognized again. With the aid of elementary results of literary history and nationalism issue research, we might find that such a statement would surely possess or provide its meaning very close to the nationalist movement. From the other point of view, if we were to say that the ethnical politicizing approximately revealed in the field of anti-KMT movement or supporting inclination of election, then the changing process of this statement will similarly show the same politicizing in the literary discourse. In brief, the main discussion of this paper is to focus on the formation and changing process of the statement "Lai Ho: the Father of Taiwanese Modern Literature", by the way, the relative or opposite voices will surely involved. Nevertheless, the attempt to clear the outline of its formation, conflict and change is our first concern.
