What perspective a writer takes to engage in a dialogue with a cultural other in the field of literature writing is the main focus of this paper. A number of excellent poems on indigenous topics have been composed by Han-Chinese writers in contemporary Taiwanese poetic circle, in an attempt to establish a de-colonized writing mode. This paper focuses on Hsiu-Chu Tsai's two works as research texts, namely Poems on the Smangus Tribe (primary) and Song of Smangus (supplement), to discuss three key aspects. First, regarding the writer, this study investigates the beginning, process, and the influence of her contact with the Smangus tribe, with a focus on how she, as an individual coming from an urban civilization to natural forests, has interacted with the tribe to seek an Eden with spiritual peace. Second, from the subject matter of the poems, this study explores the topics on the subjectivation and cultural-identity of indigenous people by examining the relationship between the texts and the thoughts of de-colonization. Third, in terms of trans-cultural writing, this study identifies the characterstics of Tsai's writing strategies to elucidate the alternative vision revealed in the writing on a cultural other, through which to fill the research gap in Han-Chinese poets' writing on indigenous topics
