Chopping cattle and playing bronze drums are the rituals of Baiku Yao for the deceased. The whole funeral is tragic and solemn, and the atmosphere of the sacrificial scene is solemn and solemn. This traditional funeral custom is not only to express the mourning of the deceased by the bereaved family, but also a common ancestor worship activity. Bronze drums and leather drums are the main percussion instruments in funeral activities.
