Old people often say that you can't look back at night.

Legend has it that in ancient times, Xuanyuan Huangdi ruled not only the world of God, but also the world of ghosts. God Rabbit and Lei Yu are immortals under Xuanyuan Huangdi, who specialize in treating ghosts who wander the world. These two immortals are guarding the gate of hell every day, looking for ghosts wandering back from the world. If ghosts are found doing evil on earth, or even hurting good people, they will definitely enforce the law impartially. Rabbit and Lei Yu are still folk door gods.

For example, on New Year's Eve every year, every household has the habit of putting up doors. At the beginning, people just carved two statues out of peach wood, put them on the doorframe and drew a big tiger to resist evil spirits and ghosts. Later, it was simply simplified to draw portraits of two gods on the door, which could also achieve the effect of exorcism. In fact, besides Shen Tu and Lei Yu, there are sixteen gods in the southern wilderness who are helping Emperor Xuanyuan to manage ghosts. These sixteen gods have narrow cheeks, red shoulders and connected arms. Sixteen gods' red shoulders are like night lights, and nocturnal ghosts dare not make trouble. So in folklore, an old man will tell the children that they can't turn back when they walk at night, because everyone has a lamp on their shoulders. If they turn around, the lights will be blown out and the ghost will attack at this time. This legend probably originated from the story of sixteen gods under Xuanyuan Huangdi. Of course, this is just a folklore, which obviously does not exist in reality.

People's names are the earliest witchcraft. I believe everyone who has seen the Journey to the West knows that the person holding the purple gourd asks, "Do you dare to promise?" Never promise, because a person's name is a part of a person, and being called by his name will react! In ancient times, it was manifested in various spells.

The Taoist book "The Law of Girls' Ghosts" says: "Knowing ghosts is auspicious, many ghosts do not do it, and thousands of gods are crouching." Buddhist daily practice says that "there is no Amitabha in the south." There is no Amitabha chanting Buddha's name in the south. Similarly, Taoism also has a practice method of chanting the name of God. For example, reading the names of the three officials can save the country. The three officials are the best in the world. Bless Tianguan and Emperor Wei Zi. The second product of the Central Plains, the official who forgives sins, and the emperor who is pure and empty. Xia Yuan Sanpin, Xier Shuiguan, Dongyin Daguan. In the west, there is also a legend that you can control goblins and wizards by knowing their real names. It can be said that both eastern and western metaphysics believe that names are part of people. According to the internet, the reason why I can't turn around and pat people's shoulders at night is because there are three light areas on their shoulders and overhead. If you turn around or pat them on the shoulder, the lights will go out. Of course, many experts are talking about this now. The saying of Sanduang District started with chicken soup, and then gradually changed into something supernatural.
