There is a dead man at home. What's with the black puppy barking at the coffin?

Sacrifice: originally refers to the tortoise used for divination in sacrifice, and later refers to praying for the actor. It is a ritual, out of one's own spiritual activities.

Dedication: Set offerings on the altar and ask ghosts and gods. For example, the cornerstone of the cornerstone is the offering, and the dedication is to ask the land to cast spells to make the house strong.

To put it simply: before burial, there is a drink offering. For example, a wreath is a kind of wine offering, and the act of saying goodbye to the giver and asking the fairy to bless is a ceremony in the process of wine offering.

After the burial, there is a memorial service, and the wreath is burned. If we go again, we will remember the mourners instead of inviting the gods, because the offerings of the wreath were burned.
