In ancient mythology, there are many things about peach trees. According to ancient records, Hou Yi was killed by a peach stick and was named Zongbu God after his death. This nerve often lives under a peach tree and leads a big tiger. Every ghost has to pass the test of the Sect God. If so, evil spirits will be eaten by tigers. According to legend, Kuafu chased the sun and died of thirst. Before he died, he threw away his staff and turned it into a peach forest so that future generations could eat sweet and delicious peaches. Because Kuafu is closely related to the sun, ghosts are afraid of peach trees.
Fu Tao: According to Shan Hai Jing, somewhere in the East Sea of China, there is a big peach tree covering 3,000 miles. The northeast branch is the gate of hell, with hundreds of ghosts coming in and out every day. There are also two immortals, Shen Tu and Lei Yu, who are good at descending ghosts. According to this legend, people carved two statues on mahogany, wrote down the names of Shen Tu and Lei Yu, and hung them by the door on New Year's Eve to suppress evil souls. This is the original "peach symbol". Later, it gradually evolved into a folk custom of hanging peach symbols.
Peach Sword: A sword used by an alchemist to ward off evil spirits. It is an important musical instrument made of natural mahogany. Folks are also mainly used to ward off evil spirits: if the dreams at night are unstable, people hang peach swords in the bedroom or put them under the bed to resolve them; In order to prevent third parties, cut peach blossoms, protect family harmony and prevent gossip, they are all hung by the window.
