As follows:
1. Zuo Fu is a kind of magic in Taoism, also known as aconite, magic seat and Dan book. Zuo Fu is a combination of Zuo Fu and Zuo Fu. Zuo Fu originated from witches and only appeared in the Eastern Han Dynasty. The Book of the Later Han Dynasty: "There was a holy monk in Henan who was good at writing Dan books and hated killing ghosts and gods."
2. Taoist symbols are widely used. Some are used to treat people's diseases: or write Dan on paper and melt it in water for patients to drink; Or seal the symbol and let the patient wear it. Used for exorcising ghosts and killing evil spirits: worn on the body or attached to the bedroom door. Others are used for disaster relief: either they are punished for stopping water supply when the river bank breaks, or they are called to fight drought.
3. As for the fasting ceremony of Taoist priests, it is even more inseparable from symbols, or the book symbols on the table, playing with immortals; Or use spells to ask god to kill ghosts; Or take care of Hades with a charm and be refined to death. Various symbols are posted and hung inside and outside the altar. The ideological basis of Zuo Fu is the belief in ghosts and gods, and it is not credible to say that it has the effect of attracting gods to solve ghosts and demons.
4. There may be other reasons why those who are occasionally called "small trials" do not expel the "ghosts" who are sick. It is speculated that some patients with mild illness have a psychological state that the ghost has been driven away and the disease has been rid of after drinking Fu Yong. This is similar to medical psychotherapy. What works is not the symbol itself, but the positive psychological state caused by the symbol.
5. Promote the human body to mobilize defense mechanisms to overcome diseases. Spells are the secret magic weapon to communicate between man and god, and you can't scribble them casually. Therefore, there is "I don't know how to draw the charm, but it makes ghosts and gods laugh;" If you can draw, you will be shocked by ghosts and gods.
6. There are hundreds of ways to draw symbols, some want to write essays about immortals, some recite spells step by step ... that is, they are elegant in laying paper, grinding ink and lifting pens, with complicated procedures and cumbersome methods, and good men and women are dizzy.
