This kind of wood is called lightning wood, which is considered to have evil spirits in folk beliefs and Taoism.
Lightning strike: refers to the normal growth of wood, and trees are struck by lightning in rainy days. Such as: jujube, peach, willow, poplar and so on.
In the northeast folk, the tree that has been struck by lightning is called lightning wood. The common people generally think that lightning wood is split by lightning from the sky, and ghosts hate it, which is the most powerful way to ward off evil spirits. Because the message that Lei Gong Dian Mu banned the spiritual body was left on Lei Mu, which was very shocking to the spiritual body and could be used as the legal object of the town house. Therefore, in the northeast area, people often tie a piece of lightning wood with a rope and wear it on children's wrists or necks, thinking that children can't "catch things" and can support themselves.
Because the lightning strike wood was cut by Lei Gong, it belongs to the innate effect of suppressing evil spirits and avoiding evil spirits in Taoist spells. And make utensils with lightning strike wood, such as lightning strike jujube seal.
