In ancient times, it was commonly known as "grass ghost" in Miao area. According to legend, it is attached to women, harming others and harming themselves. Those so-called witches are called "grass ghosts". After investigation, some Miao scholars believe that almost all Miao people believe in this law, but the weight varies from place to place. They believe that in addition to the above-mentioned emergencies, some intractable chronic diseases such as cough, hemoptysis, dull complexion and emaciation, as well as chronic diseases such as visceral discomfort, bowel sounds, abdominal distension and loss of appetite are all available. It's sudden, so it's good to let the so-called liberators get it back by calling the village. If you are a chronic patient, you should invite a wizard to "drive away the poison". This daunting method is not the exclusive right of Miao people. Magic techniques were widely spread in ancient Jiangnan area of China. Method originally refers to insects born in utensils, later moths born after food spoilage, and insects born from other objects are also called methods. The ancients thought that this method was mysterious in nature and extremely toxic, so it was also called poison method, which could enter the human body through diet and cause diseases. The patient seems to be confused by ghosts. Most of the ancient poisonous insects mentioned by pre-Qin people refer to mysterious poisonous insects that naturally occur. Long-term superstition of poison law has formed the concept and practice of making laws to harm people. According to scholars' research, during the Warring States Period, some people in the Central Plains used and taught the method of sinning.

Second, the legend

Dharma is a kind of witchcraft that uses poison to pest people. It is an ancient mysterious and horrible witchcraft, which is mainly popular in southern China and some ethnic minorities. Millet stored in the warehouse for too long, the skin shell will become a flying insect, the ancients also called it a method. Zuo said in A.D.: "Flying Valley is also magic", "Flying Valley has accumulated over time and become flying magic, which is called magic". Flying insects from chaff are different from rice bran: flying insects can fly, but rice bran can't. Kong Ying Da's Notes to Thirteen Classics said: "Poisoning people without knowing it is poison." . "Compendium of Materia Medica" says: The maker catches all kinds of insects and puts them in a vessel. This 100 worm eats the small one and the last one lives in a vessel. It can be seen that the cockroach was originally a specific medicine for treating toxic sores, but it was later used to harm people-"Put hundreds of bugs in an urn, and after opening it for many years, a bug will eat all the bugs. This is called cockroaches."

Third, the production method

12 kinds of poisonous animals, such as snakes and centipedes, were buried at the crossroads, taken out 49 days later and stored in incense burners. This is the gold silkworm Act. It is said that this method is the most difficult to destroy because it is not afraid of muskets. There is a legend in Longxi County, Fujian Province that gold silkworm is an invisible thing that can do things for people. For example, if you want to transplant rice seedlings, show it one first, and it will plant a whole mu of seedlings. It is diligent in sweeping the floor and keeps gold silkworm's house clean. As soon as I entered the house, I kicked my foot on the threshold. Looking back, the sand on the threshold suddenly disappeared, and I knew that this house was guarding the practice of gold silkworm. According to local legend, the golden silkworm method likes to eat people, and it will eat a person for several years. At the end of the year, the owner must settle accounts with it. If there are any extra ones, he must buy someone to feed them. Therefore, when settling accounts, the host will say, break 20 bowls, tell it, lose money without interest, and buy someone to feed it next year. However, the stories of Nanjing people are similar. They said it was a problem to raise gold silkworm, and the gold silkworm method was usually placed beside urinals or where no one was there. Don't let anyone know, otherwise it will be exposed and lead to fatal disaster. Gold silkworm can be deformed, sometimes shaped like a snake, or a frog, or a foot-tall child jumping around the house in a red trousers. People who raise gold silkworm seldom get sick, raising livestock is easy to grow up, there is no danger of death, and they can make a fortune. At the end of each year, the host will settle accounts with gold silkworm behind the door, saying that he broke a batch of bowls and spoons this year, which caused great losses. You said that if you made a profit this year, your family would gradually die, and the people who raised gold silkworm would not have a good result. This is called "eating the tail with gold". In this case, people will marry gold silkworm in time. The method is to wrap a bag with cloth and put silver, pollen and incense ashes at the intersection (that is, gold silkworm method). People will naturally pick up silver eyes when they see them. If they take the silver bag by mistake, gold silkworm will follow him.
