Sacrifices of various foodstuffs are presented in order to please the spirits.
Since these foodstuffs have been prepared and pre-arranged on the altar tables, the deacons merely move and replace the three-legged metal cauldrons to symbolize the preparation of the food.
Ancient sacrificial concepts in accordance with the principle of "in death as in life", whereby items offered in sacrifice are the same delicacies that the objects of sacrifice would have enjoyed their lives while they are still on this earth. Such a practice helps those still living to entertain thoughts of the deceased, as if the deceased were still alive.
