According to the information on the Internet, although both of them have western medicine backgrounds, they can't talk about keeping in good health, but because they are medical professionals, they still have some experience in keeping in good health. The question now is not whether they are health experts, but that many experts only sell drugs or advertise for medical institutions on TV, especially on the radio. The way to identify them is to see if there are advertisements in their health guidance. If they spend a long time talking about products or hospitals, we can completely deny it. At least we can regard his visit as "fooling". However, I think there are still some health knowledge to learn from the videos of these two people online. You can look for them online again.
