According to official website Query Finance and Comment Network, MLM refers to the behavior that organizers and developers illegally acquire wealth through developers or require developers to obtain the qualification to join on the condition of paying a certain fee. The essence of pyramid selling is Ponzi scheme, which is to distribute the money of latecomers to the income of pioneers. Sister Rong's psychology of creating wealth is to help people find ways to create wealth, and it doesn't need the developed personnel to pay a certain fee, so Sister Rong's psychology of creating wealth is not pyramid schemes.
