The heart corresponds to the tongue, the kidney to the ear, the liver to the eye, the spleen to the mouth and the lung to the nose. These are some corresponding ways handed down from ancient Chinese medicine. I think there is some scientific truth. After all, this is not groundless. It is a rule discovered through hundreds or even thousands of years of practice, that is to say, some lesions in our internal organs will make our face appear any abnormality.
Chinese medicine has always paid attention to seeing, listening and asking questions, because in such an environment in ancient times, there was no developed medical technology now. Through various machines, we can diagnose whether there is inflammation inside a person's body and whether there are other symptoms. At this time, by observing a person's face, that is, the most basic vision, we can infer where some diseases actually occur, and then by taking the pulse and asking the patient's condition, we can determine what is wrong with this organ and prescribe the corresponding prescription.
Up to now, the five senses corresponding to the five internal organs have become a theory of health preservation, which tells people that there is such a corresponding relationship, and then we can judge a person's health by observing some characteristics of his face. Of course, we are not professionals, and I have no way to judge whether this person is healthy or not. It's just a hobby. As ordinary people, we don't need to study what kind of correspondence he will have. All we know is that there is a mutual correspondence.
