This study focuses on the ethnic relations between the Hakka and Saisiat in Donghe through the analysis on the food, Hakka’s “Chi-Ba" and Saisiat’s “Tinawbon”. On the one hand, we explore the food’s role on the classification of people and social categories; on the other hand we try to interpret the food’s engagement in everyday life and the people’s sensual experience. Based on these studies, we attempt to explore the food’s role on the mitigation of the inherit tension between the ethnic groups and the maintenance of their ethnic boundaries.
