Customs and habits
They build houses usually with three rooms and live close together. The families of the same lineage always reside together. In a Hoa family, the husband is the head of the household. The right of inheritance is reserved for the sons only. The eldest son always gets the greater part of the property. Parents decide the marriage arrangement of their children, and early marriages are common. The choices of a husband or a wife are often based on the desires of the family to have equal social standing or are dictated by business considerations.

According to customs, funerals must go through several rituals. The cycle starts with informing others of the mourning process, wearing mourning clothes, wrapping the corpse, opening the road for the dead soul, burying the dead, bringing their soul to the "country of Buddha in the west", and the last rite is the completion of the mourning process. Since respect for the dead is very important, in all villages and hamlets, there are temples, pagodas, and shrines built for veneration of the dead.
