Miaojiang method is related to insects, and the so-called Thai method should be called head-dropping. 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 long-term cough, hemoptysis, dull complexion and emaciation, as well as symptoms such as visceral discomfort, bowel sounds, abdominal distension and loss of appetite are all possessed by this method. 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. According to folk tradition, Nanyang's head-dropping technique comes from Hinduism. When Master Sanzang of the Tang Dynasty went to India to worship Buddha for Buddhist scriptures, he passed through the Annan Tongtian River, which flowed into the upper reaches of the Mekong River in Siam, and sneaked into the bottom of the river for the tortoise to kill the Tang Priest. Although the Tang Priest didn't die, all the scriptures he was looking for sank to the bottom of the river. Fortunately, his disciples fished them out of the water, but only a part of Mahayana was recovered.

On the other hand, the original of this "prophecy" flowed into the hands of Taoist priests in Yunnan, and a school of "Maoshan Taoism" was founded. As a result, Maoshan's spells and head-dropping techniques all came from this, and the means were relatively high. So some people say that Siam's head-dropping technique came from Yunnan, China.

Some people also say that Siam's head-dropping is a fake copy or handwritten copy of "prophecy", lacking a lot of dharma, so the kung fu is weaker than Maoshan. China ancient books recorded that "Maoshan" was the name of a mountain in the southeast of Jurong County, Jiangsu Province, China, formerly known as "Qushan". Mao Ying of the Han Dynasty and his two younger brothers, Li Mao and Mao Gu, came to live in this mountain. The world calls him "San Mao Jun" and this mountain "Mao Shan". Maoshan art was created by Sanmaojun, also known as "the art of jade girl and western gods".

Some people say that Maoshan School is another Taoist school besides the "Five Thunder Religion" in Zhang Tianshi, which is also a kind of "Southern Buddhism". The techniques of "ring light" and "Zhu Youke" are all techniques of this Maoshan.

In the Song Dynasty, there were many records about Maoshan witchcraft in Song people's notes, which showed that Maoshan witchcraft was quite popular among the people at that time. Since then, more and more overseas Chinese have crossed the south, using it to resist the infringement of "head-dropping".

According to China's historical records, Maoshan Magic was invented in the Han Dynasty. According to legend, falling head is a "prophecy" for Tang Sanzang to learn from the West and find back his lost legacy. Whether it is true or not, we can see that the discovery of head-dropping technique is superior to Maoshan technique, and it is natural that Maoshan technique is superior to head-dropping technique.
