You Zhu was a magical witchcraft in ancient times, and it could also cure diseases, but it was regarded as a feudal superstition by modern people, so no one used it any more. In ancient times, people who could learn from You Zhu had to undergo strict selection and had certain talents. Not everyone is qualified to study. Besides, before learning from You Zhu, wizards must swear a very vicious oath. For example, I'd rather lose my children and grandchildren than have the magic work. Therefore, malicious people learn this technology, which is likely to harm people.
There is also a kind of example, that is, not eating for life. Then you have to go through complicated procedures such as cultivation, and then you can really treat people. In addition, without guidance, if the practice is biased, the consequences will be very serious.
The Development of You Zhu Art
According to Liu Xiang's Shuo Yuan, in ancient times, there was an imperial doctor named Miao Fu, who used straw mats to make patients sit and lie down with themselves, and tied children into the shape of dogs with grass. For any patient who comes to ask for help, he picks up a grass dog, faces the north and mumbles, and only reads ten words for each treatment. Therefore, whether lifting or not, the patient can recover as before. Miao Fu's method of treating diseases belongs to You Zhu. In early civilizations around the world, wizards and doctors were inseparable.
Witchcraft was a very noble profession in early civilization. It used to be an official name, and only people with high educational level can hold it. They are familiar with astronomy and geography, can communicate with ghosts and gods, and control the blessing and disaster prevention of the country, in important affairs such as diplomacy, war, funeral sacrifices of kings, queens and nobles, herbal bathing, physical and mental health and so on. It was not until there appeared a doctor who could treat people with drugs instead of witchcraft that wizards and doctors gradually separated.
