Experience of watching Song Yifu's lecture

It's very real and practical. Song Yifu often said, what is expensive is not necessarily good, but what suits you is the best. That's the way to keep healthy. No matter how expensive things are, they don't suit you. For your health, they are equivalent to garbage. No matter how cheap things are, they are good for your health. That's a treasure. Song Yifu always mentioned some cheap and practical foods and health preserving methods in his lectures, for example, it is good for hypertensive patients to eat celery and tomatoes. And people can accept it. Song Yifu often warns some elderly people that they should go to the hospital for examination if they are sick, and don't treat themselves. In order to save money, many old people think that minor illnesses can be treated by themselves and take some medicine. After watching Song Yifu's lecture, they realized that some diseases in the later period might be caused by these insignificant problems, which sounded the alarm for many people and felt that they had benefited a lot from his lecture.
