"buying water", a ceremony carried out by the eldest son for a dead parent. With a traditional funeral, the chief mourner (eldest son) is escorted to the nearest stream or well, drops three cash into it, and brings back a bowl of water. The corpse is then bathed or is symbolically dabbed on the forehead with some of the water. Sometimes, a husband would justify getting a concubine because having no male heirs would mean that he had no one to buy water for him. The ritual signifies filial piety and ensures that the lineage continues.
