At present, the mode adopted by most WeChat businesses is actually similar to that of pyramid schemes, but the biggest and most fundamental difference is whether it is legal or not. The legal basis is that pyramid schemes have no physical stores, that is, they rely on constantly attracting people to get commissions, or on constantly paying for goods to get commissions, regardless of how your goods are sold or after-sales, so you must know more about the nature and operation mode of this company in advance before deciding whether you want to join.
