The accomplishment of contemporary Bunun literary narratives, creations, and writings, including the three communication modes: singing and talking in oral literature, writing in writer literature, and digitalizing in cyberspace literature, has equipped with, from either a quantitative or qualitative perspective, the outlines for compiling ‘History of Bunun Literature’. This paper explores the current accomplishment of ‘Bunun literature’ in relation to the structure significance of ‘History of Bunun literature’ in the future, as well as attempts to figure out the similarities and differences between ‘Bunun literature’ and the literature of other indigenous peoples. While working on many a Bunun indigenous literary writer’s cultural and identity development, this paper also studies Bunun narrative oral literature, writer literature, and their contextual and structural relations, in order to understand formation and structure of ‘Bunun literature’ in different social and cultural spaces. The scope of investigation in this paper focuses on the following three overlapping aspects: (1) Bunun-born literary creative writers and the significance reflected by the writers’ life stories; (2) historical memories revealed by textual spaces and trails of cultural imagination and social adaptation; and (3) the map of choices made by Bunun-born literary creative writers for cultural practice strategies and literary communicative modes. Such an exploration of the rich ‘Bunun literature’ is considered as a key step for structuring ‘history of ethnic literature’ for Taiwan indigenous peoples.
