The Paiwan (Payuan) link politics, marriage, religion, and art with the family names, clans and a rigid social hierarchy. After the millet harvest, they hold the “Millet Harvest Thanksgiving Ritual”. The Vuculj subgroup holds the Maleveq Ritual every five years to welcome the ancestral spirits to visit their descendants. It is also called the “Human-Deity Alliance Ritual”. Today, the Paiwan has a population of around 102,730 people (as of January 2020).
