A sacrifice to the ancestor spirits. The ritual objects are arranged on an altar table in front the house. The Shaman invokes the spirits. His body is moved convulsively indicating that he gets possessed by the spirits. After having completed the invocation he throws oracle rods to inquire whether the sacrifice has been accepted. An animal sacrifice is then performed consisting in the slaughtering of a hog, the blood of which is finally sprinkled over the altar. The hog is then scalded, its bristles removed, it is washed in the river and cut up. Its head is placed on the altar, in front of which the Shaman renews his invocations and throws the orcle rods once more. Finally, members of the family remove the altar.
