Through historical investigation and archeological excavation, the Suikunto Port in Mattaw, Tainan, has been proven to be the last remaining relic of the interior ports of the Qing dynasty in Taiwan. This inland Mattaw Street area, near the Tohong sea, became the location for the settlement of the Mattaw people. Prior to the seventeenth century, the people of Mattaw were the strongest tribe of the southwest plains; until the beginning of the Qing empire, they enjoyed superior status, and greatly influenced trade activity in the port. The people of Mattaw began to be “civilized” under Dutch rule; historical records describe obvious differences between the former and the Pinpu people of North-Central Taiwan, such that the Mattaw tribe began purchasing land formt he Han Chinese in a phenomenon termed “reverse handling.” However, after the rise of the Qianlong emperor, the Mattaw people were incapable of resisting national policy and the invasion of Han Chinese cultural influence, and were thus either assimilated or relocated to other areas. When relocated to Mattaw Street or nearby Shuikutou, this became the new commercial center. The changes of Mattaw Port Street, though influenced by the surrounding environment and the Han Chinese, weer also the result of this intrinsic influence of betel nut residences. Together, these factors spurred the creation of not only the developed village structural model of twelve blocks seen today, but one of Taiwan’s few, large-scale commercial-rural compound villages.
