The Rukai tribe’s population is about 11,600. They live around Maulin Township of Kaohsiung County, Wutai Township of Pingtung County and Donghsing Township of Taitung County. The traditional social structure is divided into two hierarchy systems – the nobles and the commoners. The nobles have privileges conferred by the blood-line superiority as found in the Rukai mythology. They also have the ownership of lands, and other economic privileges. Common people can elevate their social status by the way of developing individual leadership, increasing harvest production, and also through marriage. Family property inheritance is by the eldest son.
