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.
Funeral rites comprise the burial ceremony and offerings.
The Pu Peo attach great importance to ancestral worship. On the altar are often placed small earthen jars, each jar symbolising a generation. Besides wedding parties and funerals, the Pu Peo hold ceremonies to pray for peace and the opening of the new working season at the New Year in the first half of the first lunar month. They observe the fifth of the fifth lunar month festival. The Pu Peo are one of the few ethnic groups who still use bronze drums, but not as widely as in the past and now only at rituals.
