The Bunong community holds a rain-wishing ceremony every April before the wet monsoon starts to come. Villagers cut bamboo trees into 2 to 3 pieces, peel the surface, and make various animal symbols. They also cut a branch off from a roka tree to make a symbol of an elephant tusk. They place all symbols together alongside traditional cakes, pork meat, pig liver and blood, two pieces of charcoal, which symbolize ancestors, and a jar of wine, which contains eggs, at their ancestors’ stupa as offerings. Older villagers play kmous, while praying for and asking the ancestors to bring them the rain.

All the villagers then enjoy lunch together. They are usually divided into three groups of women, men, and children. After finishing the ceremony, the participating villagers divide the remaining meat among themselves.
