The focus of this year’s ethnographic survey is the traditional livelihood and economy of the Bunun and the changes they have faced since the end of Japanese occupation. We’ve discovered that the sharing relationship is a key feature of the Bunun economic life. However, due to their different status because of past migrations, the Dongpu and Meishan village settlements show a marked difference in their sharing relationships. The focus of the topical survey was on “the music used during yearly sacrifices offered to gods or the deceased.” The survey showed that general ethnographical data must be combined with the study in order to understand and interpret the music used during yearly sacrifices offered to gods or the deceased, such as the distribution of Pasibutbut. When trying to understand the deeper meaning of their music, it is especially important to conduct ethnographic studies on the social culture of the Bunun.
