Is there anyone who knows medicine who can expose the lie of Yu Yang, a liar who talks about health preservation in Zhejiang Sci-Tech University, and come out to popularize relevant knowledge? Kneel down! Yu Yang is a liar. He cheats retired old men and old women. She has the heart to get sick. It's all health food, and the price is 700 to 800 yuan, which has no effect. It's amazing on radio and TV. Find a bunch of childcare and make a phone call. It is inevitable that you will be cheated when you are old and have poor discrimination. But what does the government regulate? Radio and TV have no sense of social responsibility, so they will give you time to brag casually.
