1. Yes. Your understanding is absolutely correct. 2. WeChat business is a bit like pyramid scheme. Because the last one has to collect commission. For example, the agent may get the goods from the manufacturer, but sell them to the next level agent. Maybe the price is 40. Then sell it to the next agent. The price may be 60. And then sell it to consumers. The price may be more than one hundred. This is all normal. 3. So you are right. So don't buy things on WeChat.
