If your hair is gray, it means that you are a very smart person with a flexible brain and an excitable person in life. In terms of yin and yang, your brain is in the perineum for a while, and your ability to control emotions is poor for a while. So all the troubles are in vain. At this time, you should pay attention to the hidden dangers in various organs of the body. Chinese medicine says that anger hurts the liver, likes sadness, hurts the spleen, fears the kidney, and the five internal organs are all in a sub-health state. Such people should learn to control their emotions and try to keep them stable.
