The Taiwan development history of modern times is actually a history of blood and tears of Pingpu tribe. As compared with the historical literature written by literati, a ballad can convey a disadvantaged group’s joy, anger, sorrow, delight, pain, and wish better. Pingpu tribe aboriginals are good at both singing and dancing; however, because of lacking for written words for a long period of time, most of the group’s ballads disappeared and were unknown, and only a really few of them were recorded via “other people (the Han people)” with characters and were kept, yet after all, those records have a gap with Pingpu tribe’s true inner feelings. “Mao-wu-shu Tribe Ballad” is the first long ballad text transcribed and recorded by Pingpu tribe aboriginals themselves for the first time; the content reveals the minority’s sadness of fast decline of economy and culture. The research tried to take the viewpoint of cultural colonization to discuss Pingpu tribe’s change on economy and culture in Qing Dynasty based on the relevant Taiwan historical literature records for Pingpu tribe since Qing Dynasty, and through the sorting and analysis of text of “Mao-wu-shu Tribe Ballad,” the research not only annotated the ballad text, but explored the disadvantaged group’s mental condition when facing the dominant culture assimilation pressure in order to achieve the research goal of “analyzing the ballad with history” and “proving the history with the ballad.”
