Using the case of Sancengpu 三層埔 (present-day Meihua 美華 and Fuxing 福興 Villages, Daxi District, Taoyuan City), this article identifies a new mode of reclamation in Taiwan following the Lin Shuangwen rebellion (1786-1788). It is true that in the post-rebellion era, the Qing dynasty continued its affirmative action, establishing the aborigine military colonies 番屯 that had dedicated funding for employing "civilized" 熟 aborigines. Nevertheless, the arrangements also enabled Han reclamation in frontier regions on the pretext of sustaining anti-"raw" 生 aborigine border guards. Chinese guards made their applications to county governments (in the case of Sancengpu, Danshui subprefecture) instead of the two subprefectures for aborigine affairs established in the middle decades of the reign of the Qianlong emperor. The new reclamation mode became the principal method for frontier developments in the history of the island during the nineteenth century. The mode had a profound impact on Taiwan's governance and society, despite being constantly and slightly adjusted owing to changes in state policy, commerce and trade, and social developments.
