This kind of pyramid selling organization usually uses the banner of "free public welfare class", "spiritual practice" and "learning Zen dance" to control students' minds through spiritual suggestion and hypnosis, and at the same time publicizes and introduces the follow-up sky-high paid courses. They also have different online publicity methods, such as WeChat official account, video number, Tik Tok number, watermelon video and so on.
I suggest you treat this kind of organization with caution, choose legal channels to study and improve your self-cultivation. If people around you are already involved, it is recommended to call the police or ask for help from relevant departments in time to avoid losses.
