Looking at the fingers can reveal part of the body’s condition, and is part of the diagnostic process in Traditional Chinese Medicine (TCM), often used in pediatric diagnosis. As younger children are unable to describe physical discomfort, and pulse positions are shorter and smaller, emotions are changeable, and the pulse is easily disorganized, so it is not convenient to ask for diagnosis, and in ancient times there was the name of mute science, while fingerprint patterns are less stimulated by emotions, so fingerprint diagnosis is a very important part of pediatrics in TCM. It is generally recommended that under natural light, after fixing the wrist of the child with the hand, the fingerprints should be pushed inward from the tip of the index finger several times so that the fingerprints will be revealed, from the tip of the finger to the palm, and according to the knuckles, they are divided into the life gate, the qi gate, and the wind gate. When the child is healthy, the fingerprints should be in the wind gate or the wind gate or the following one, and the color is reddish-yellow and vague but distinctive. If the fingerprints are darker in color and spread to the fingertips, it generally suggests that the child’s physical state is not good, and generally the closer the fingerprints are to the palm, the lighter the condition is, and the better the child’s physical state is. In addition, you can also judge the heat and cold of the child’s body through the color, generally red represents the disease is hot, purple represents the disease is cold, the location of the veins is usually shallow for the surface evidence, the location of the deeper is considered for the internal evidence. Finger to see the physical condition can only be used as an auxiliary means, and can not be completely clear the specific condition of the body, it is recommended that if there is physical discomfort or suspicion of their own physical problems, should go to the hospital in a timely manner, through modern tests to clarify the condition.
