If middle-aged and elderly people can still have clear eyes like children, it means that they are in good health and are not troubled by any diseases. This is not a subjective feeling, but a certain sense of traditional Chinese medicine. The eyes are where the human body gathers energy. If there is a god, it means that this person has a good physical quality. If mixed with red blood, there is no god, indicating that this person's kidney and liver have a greater impact.
China people like to use an idiom to describe a passionate person, that is, the voice Hong Zhong. In fact, it makes sense from the perspective of Chinese medicine. Loud voice is the expression of sufficient yang in the body, and foreign harmful bacteria are not easy to invade the body. Careful observation will show that those who look weak are weak and gentle. If the middle-aged and elderly people speak louder and have no noise, it means that they are in good health.
Nowadays, many middle-aged and elderly people have poor gastrointestinal digestion, and constipation often occurs. Some elderly people defecate once every three or four days, and the whole process is not so smooth. Constipation is harmful to human body. After a long time, it is easy to suffer from diseases such as intestinal cancer and intestinal ulcer, which seriously affects health. If middle-aged and elderly people can defecate once a day, it means they are in good health. Even if they can't, it's good to defecate once every two days.
