Ba jiao gui are known as banana ghosts as they live in banana trees. They are typically depicted as women dressed in a white or a red gown, often seen cradling a small infant in their arms.
According to superstition, there is a ritual to exploit these spirits to win a lottery. The ritual involves tying a red string around a banana tree trunk and securing it with a nail driven into the tree. The other end of the string is then attached to one’s own bed. This act is said to torment a ba jiao gui, forcing her to provide winning lottery numbers in exchange for her freedom.
However, amassing wealth in this manner comes with significant risk. The tormented ghost would hold a grudge against the person and wreak vengeance on them once she’s set free.
