Psychologist Wu Zhihong once said, "Every disease is an expression …". Emotion plays a coordinating role in the physiological function of the body. If the emotional activity is abnormal, it will lead to emotional out of control, which will lead to nervous system dysfunction and premature aging. Hate sadness, anger hurts the liver, resentment hurts the spleen ... the mind is very important to the body, and the same health care is of great benefit to both body and mind.
