In the Ta oi village, the communal house called mng is built in the centre of the village while in some certain places, there exist "spirit houses" built on outskirts of the habitation which are the place to focus the villagers whenever festivals and public activity occur.

 

The ordinary house is fairly elongated. The interior is divided into rooms by partitions. Each room reserves for each small nuclear family. A space floor reserves for receiving guests and meetings of the family reunion. These elongated houses have gradually disappeared.

Each Ta oi lineage has its own name and certain taboos. Legends are written down to explain such name and taboos. The children take the family name of the father. Only the sons have the right to inhert family estate. The head ofthe lineage plays an important role even in village affairs.

They arrange to meet each other in the fields and exchange "belief objects" with each other, then the family of the young man relies on a matchmaker's assistance in proposing marriage from the family of the young woman. After the wedding, the bride becomes a member of her husband's family. Marriage between decendents of paternal aunt and maternal uncle is encouraged, but if a man of A lineage marries a woman of B lineage, thus marriage between man of B lineage and women of A lineage is prohibted. He must choose his wTe of other lineages.

The Ta oi believe in animism and organize many ceremonies to venerate Giang (genies) for protection of human beings, crops and animals.

According to custom, several years after burial, the dead's lineage organize a ceremony to reinter the dead remains and build funeral house with sophisticated decoration and statues around the house's fence.
