In fact, the understanding of health and disease has not changed since ancient times. Prevention before illness is not proposed by modern times, nor is it proposed by modern times. In terms of disease, the disease is from shallow Chinese medicine. This can be seen from the meeting between Bian Que and Cai Huangong. And this theory is consistent in the world.
The only difference between now and ancient times is that with the improvement of material, we begin to pay more attention to our health, not just to live. Of course, this is aimed at the bottom crowd, and the top and middle levels have always been very concerned.
