What is the implication of the custom of throwing urn at funeral after the death of the rural elderly?

This is a custom handed down from ancient times, and many people in rural areas will do it. In the first few days, this gray basin is usually placed at one end of the coffin. There are also many ceremonies, such as burning paper money in it. On the day of the funeral, the ash basin will be thrown, which also has special significance in people's hearts. People's birth, aging, illness and death are natural laws. People cannot live forever. Everyone has to go through birth and death. As relatives and friends of the deceased, it is very sad. Rural areas are different from cities. Old people in rural areas usually put a basin at one end of the coffin after they die. With the progress of the times, this kind of basin will not have much to do with it, as long as it is a basin. A few days before the funeral, we have to cross over and our relatives have to turn around the dead. I heard that this can make the dead cross over better. In this process, children and grandchildren will burn paper money in the basin so that the dead can be brought back to the underworld. At the funeral, this kind of gray basin must be broken, and in everyone's opinion, the more broken the better. After being broken, the deceased can take this basin back to the underworld for future generations to use when offering sacrifices. It's broken because it's easy to carry. It is usually the eldest son who falls down when throwing the ash basin. Some people say that this means inheritance, which is Fan Li's allusion. Moreover, as a child, my heart is heavy. In order to make the dead live a better life in the underworld, I am also seriously throwing ash pots. It is said that people can't come back from the dead, and they do these things just to relax their loved ones and give their hearts a sustenance. In any case, as a traditional custom, it plays an important role.
