If you mean Guo, a Chinese medicine teacher who speaks Mandarin, then I can tell you that it isn't. Because on the surface, she didn't participate in any business activities, and the lectures were serious, useful, pragmatic and free. But she has an assistant who sells all kinds of drugs at unacceptable prices. You don't have to buy this.

Teacher Guo is the anchor of Himalayan platform. He often gives you some tips for keeping in good health, and he only sells products part-time. Driven by him, the seven-flavor breakfast paste bought by ordinary people was well received.
