Pas-ta'ai (Chinese: 矮靈祭; pinyin: Ǎilíngjì), the "Ritual to the Spirits of the Short [People]", is a ritual of the Saisiyat people, a Taiwanese aboriginal group. The ritual commemorates the Ta'ai, a tribe of short dark-skinned people they say used to live near them. The ritual is held every two years and all Saisiyat are expected to participate.
