As to the policy of governing ethnic minorities in Taiwan Province, the Qing (1644-1911) government first set up “minority borders” to separate Han immigrants from ethnic minorities. It not only prohibited Han immigrants from entering “the land of the minorities,” but also prevented ethnic minorities from intruding Han immigrants. With the advancement of land reclamation by Han immigrants, the Qing court constantly adjusted the relationship between Han immigrants and ethnic minorities, and gradually carried out land development in minority areas. In the late Qing Dynasty, the invasion of western powers and Japan triggered a serious border crisis. In order to strengthen Taiwan’s coastal defense, the Qing government implemented a policy of “nurturing the minorities with open borders,” further accelerating the process of Taiwan development, and making the mountainous minority areas completely included in the unified Chinese governance system, becoming an inseparable and important part of China’s territorial and sovereign integrity.
