Pas-ta'ai(矮靈祭), the Ritual to the Short People, is a ritual of the Saisiyat people, a Taiwan aboriginal group. The ritual commemorates a tribe of the "Little Black People" they say used to live near them. Some anthropologists believe these may have been a tribe of Negritos or Proto-Australoid people who lived in Taiwan centuries ago, possibly arriving during the coastal migration, although no Negritos remain in Taiwan today.
