Is it illegal to use Taoist divination to save lives?

According to the law, you can't use feudal superstition to deceive people and collect money, endangering your life. Traditional Taoist magic has reasonable components and operating methods, but it may not be recognized by public security organs or social supervision departments. Whether you really have magic or not, it is easy to be misunderstood as engaging in feudal superstitious activities. So I suggest you keep a low profile. Don't do it without absolute certainty.
