The Siraya was not officially recognized by Taiwan government because of its Pinpu background. In 2006, the Siraya is recognized by Tainan County and becomes the first county-recognized Taiwan indigenous population. This development will bring some good effects to the Taiwan indigenous politics: Pinpu peoples turn to self-identify as indigenous peoples; the population recognized by county can release the pressure against central government; the cultural population becomes another category of indigenous populations; and the relation to the land turns into another important criteria to identify the membership.
