Witchcraft is an attempt to influence or control some people and things with the help of supernatural mysterious forces. In ancient times, female performers were called witches and wizards. From the nature of witchcraft, witchcraft can be divided into black witchcraft and white witchcraft. Black witchcraft refers to witchcraft used when framing others; White witchcraft is used when praying for good luck, so it is also called auspicious witchcraft. Judging from the means of witchcraft, witchcraft can be divided into two categories, one is imitation witchcraft and the other is contact witchcraft. Imitation of witchcraft is a kind of witchcraft means that uses similar things as substitutes for good luck or disaster. If you hate someone, take a human form and write down that person's birthday, or burn it, or splash water, or stab it with a knife and let that person die. In nature, this belongs to black witchcraft. Another example is that children often fall into wells. In order to avoid disaster, they often make a puppet instead of a child and throw it into the well. This kind of behavior is called breaking the evil spirit.

Contact witchcraft: it is a kind of witchcraft means, which uses some things or things related to things to seek good luck and frame bad luck. This kind of witchcraft can achieve its goal as long as it touches a part of someone's body or someone's equipment. If someone is sick, put a coin or something more expensive where the patient is sick, and then throw it on the road for anyone to pick it up, so that the patient is transferred to the picker.

In Liangshan Yi people, when the slave owners found that the slaves had escaped, they not only sent people to look for them, but also asked the wizards to practice witchcraft. The method is to bring the rags left by slaves and put them in a stone mill for grinding. Because cloth is not easy to grind down, they think that slaves will inevitably wander in the mountains and find no way to escape. In order to escape from the jaws of death, slaves also fought against witchcraft. Generally, when they escape, they carry a small stone mill on their backs and put it on their heads, so that the cloth ground by the slave owners will fall off quickly and they can escape successfully.
