These are what the Chinese used for when someone dies they burn them and I guess it for wealth search it up its not what you think trust me I thought the same thing when I first heard of them
i did some research is this right ? Hell banknotes are used in Chinese cultures to pass money to deceased ancestors by burning them. Chinese superstition has it that giving a hell banknote to a living person is wishing them to be dead and it is considered very bad luck to keep them in the house.
