The Sediq society is a patrilineal society. On job sharing within the community and families, except heavy laboring works and hunting are carried out by men, there are no gender specific limitations in general tasks and jobs. Sediq people practice monogamy. According to gaya’s (ancestral rules) code of marriage, cohabitation, infidelity, and unwed motherhood are strictly prohibited.
The chief is the community leader of the Sediq community. The chief is elected among intelligent and righteous people to represent the community in foreign affairs, negotiations, and settle disputes and maintain community harmony and peace. The heredity of the chiefship from the father to the son and the elder brother to the little brother is allowed with the recognition and trust of community members. In addition to competence, community’s recognition is also the key. Mona Rudo, chief of the Mahepo Community of Seediq Tgdaya, who led the Mushe Incident in 1930 is a good example. He was elected as the chief for this intelligence, excellence, and courage and he earned the appreciation of former chief Temu Robo and the recognition from members of the Mahepo Community. After taking up his chiefship, Mona Rudo was invited to visit Japan by the colonial government. Although he knew that Japan was advanced and powerful, due to the prejudice and exploitation of the colonial police, he decided to rebel after many conflicts. On October 27, 1930, Mona Rudo led the resistance against the colonial government on the sports day of Wushe Public School. The incident shocked both the colonial government and international communities.
3. Gaya (Ritual Group)
“Gaya” is the important code of conduct and code of ethics in Sediq culture. As ancestral spirits will bring bad luck to the community for violating “gaya”, Sediq people follow these rules very carefully to avoid group endangerment. The context of “gaya” is the same in Sediq, Truku, and Atayal cultures. It refers to the systems and rules established by ancestors. Any gaya member who breaks the rules or disobeying taboos will affect all gaya members. Therefore, other members will request for redemption. A gaya group is formed by one or two close relatives as the core member(s), other distant relatives or relatives-in-laws, as well as friends without any lineal relationships can also joint the gaya group. Members of the same gaya group must farm and hold rituals and obey the taboos together; “gaya” intergrates religious, geographic, and lineal relationships. Studies of Sediq gaya found that the relationships between a gaya group, the community and a clan is comparatively clearer due to the well-defined geographic groups of Sediq people.
