We start with a review of the migrant patterns of the Kahabu People within the Puli Basin. Secondly, we examine how the pre-war Japanese and post-war Taiwanese scholars have their judged how the Kahabu People are termed and classified. Efforts are then made to look into how they refer to themselves. Further, we undertake to describe how they have attempted to organized themselves after the 921 Earthquake in 1999 with a special focus on how they have extend their care from ritual representation and tribal organizations to the ethnic recognition of the Plains Indigenous People since 2005, particularly the involvement with the name rectification movement.
