Under the guise of free study (first time in 500 yuan) and "love" and "public welfare", we are actually doing "spiritual pyramid scheme", the last variant of traditional pyramid scheme. It is said that it is "the ultimate variation of pyramid scheme" because it seems to have nothing in common with "traditional pyramid scheme", but it has almost the same genes as pyramid scheme. The design of this course is very rigorous and exquisite, and the designer should have a considerable psychological background. The course uses many psychological principles, the design is interlocking, the students' spirit is controlled step by step, the lecturer guides the students' thoughts, and finally achieves the goal of making profits, turning the students into free "salespeople" in the company. We know that in order to hide people's eyes and ears, the forms of pyramid schemes are constantly changing, making it difficult for ordinary people to distinguish them.
