Customs and habits
Pa Then houses are built either on stilts, level with the ground, or half on stilts and half on the earth. Marriage is strictly forbidden within the same lineage. According to customs, after marriage the husband lives with his wife's family for a certain amount of time. If the wife has no brothers, the husband will live with his wife's family forever, and he has to worship the spirits of his wife's family. Half of the children take the family name of their father, and the rest takes the family name of their mother. The Pa Then worship their ancestors at home. They worship the spirits of the soil and the new rice crop, pray for the rain, and worship the souls of the dead.
