This is how merchants on Taobao sell things. They all played the big flag and blew loudly, but things were not so good. In fact, many people buy things on Taobao for cheap, and I often sell things on Taobao, but I basically buy clothes. I have also seen Bian Shi on Taobao, which is worse every time, what Yang Yi recommended, and so on. Teacher Yang Yi is an expert in TCM health preservation. She doesn't sell Bian Shi at all. This bad behavior is a complete infringement. Especially those "three noes" products, as well as stones with unknown composition sold by merchants who steal test reports from other manufacturers, some stones with unknown composition will have radioactive effects on human body and cause harm to human body. We should pay attention to honesty in doing business, and we should not ignore the health and safety of consumers because of a little interest.
