Those health care methods can be described as mixed fish and dragons, which need to be screened and selected. Because I also answered health-related questions on the website and was once rated as an expert. Fortunately, I still know my weight. I only choose the methods I have experienced with people around me to answer. And some people are dumbfounded, make people clear (sometimes I am no exception), just ask for the number of answers, regardless of the consequences. So those materials can only be used for reference, not copied.
