Why are Chinese medicine, Qigong, Feng Shui and Buddhism and Taoism swindlers prevalent?

First of all, there is something wrong with your title. Why are there cheaters in the circles of Chinese medicine, Qigong, Feng Shui and Buddhism?

Chinese medicine is Chinese medicine, qigong is the essence of Taoist philosophy and health preservation, geomantic omen is an important part of metaphysics, and Buddhism and Taoism are the representatives of religions in China. If the subject does not understand the above, you can refer to the relevant information. It is meaningless to attack the above topics by asking questions, except to confuse the audience.

As for why there are liars? Western medicine, yoga, fitness, electronic information, which industry is not a liar? It can be said that as long as the common sense in the discipline is not known to the public, then some scum in the discipline can cheat through these "common sense" information-in a word, the ignorance of the masses and the existence of scum in certain industries. As long as these two factors are met, then fraud can be carried out.

Judging from the expression of the topic, the subject is hostile to the above-mentioned subject-in fact, in the modern society where search engines are so developed, I don't believe that the subject can't obtain relatively objective and credible information. Then why are you still hostile to the above subjects? The author needs the subject to reflect.
