貝神祭之由來：很久前hla'alua（拉阿魯哇人）與kavurua（小矮人）曾經同住在 hlasunga 這個地方，而takiarʉ（貝神）是小矮人的守護神。小矮人與拉阿魯哇族人相處非常的融合，有一天拉阿魯哇的祖先要離開hlasunga 這個地方，小矮人很難過，於是當拉阿魯哇族人要離開時，就把他們最珍惜的寶物─貝神贈送給拉阿魯哇祖先，並且交代拉阿魯哇族人要把貝神奉為自己的神來祭拜，於是十二貝神從此就成為拉阿魯哇的神了。
The most important ritual of the La Aruwa tribe is "miatungusu (" Holy God Offering, "or" Holy Shell Offering "). It was originally held once every two years, but it has been held annually since 1994 for cultural heritage.
The origin of the shellfish festival: long ago, hla'alua (la aruwa) and kavurua (dwarf) lived together in hlasunga, and takiarʉ (shellfish) was the patron saint of the dwarves. The dwarves and Laaluwa people are very integrated. One day, the ancestors of Laaluwa want to leave the place hlasunga. The dwarves are very sad, so when the Laaluwas want to leave, they will treasure their treasure ─She gave it to La Aruwa ancestors, and explained that La Aruwa people wanted to worship Phai God as their own god, so the Twelve Phai God became the god of La Alua.
