Houses are built on the ground in tiny clusters near Hoa and Mong settlements. Each family lineage has its own system of middle names given to successive generations. Young men and women of various lineages enter into marriage according to matrimonial custom. The groom's family seeks marriage for him and, after the wedding party, the bride joins the family of her husband. The Pu Peo family follows the patrilineal system, and the father or husband is the house owner.
