Mingbi is one of the mingbi used by China people to worship ghosts and gods and appreciate the dead at funerals and grave-sweeping. It is also called paper money, mingbi, gold paper, silver paper and cat paper. Generally, white paper is cut into the shape of copper coins, and then it will be scattered in the cemetery in the wild or burned to the dead. People generally call this kind of paper loose burning.
Most secret currencies must be burned with fire. However, when the deceased goes to the funeral and carries the coffin, some family members will throw paper money on roads and rivers to the ghosts and gods on the roads and rivers to avoid embarrassing the deceased. This is called "buying money for the road". Others put paper money in coffins and buried it with them.
Traditional paper money is divided into two types, one is used to worship gods, and the other is used to worship ancestors and ghosts. Relatives hope that the deceased can live a happy life in the underworld, so they burn Mingbi or other paper offerings. Others believe that burning paper money can bribe ghosts and gods in the underworld and reduce the punishment of the dead in the underworld.
