Six meridians, including lung meridian, large intestine meridian, pericardium meridian, triple energizer meridian, heart meridian and small intestine meridian, start and end in the hand. "Palmar area", that is, the center of palm is the place where acupoints related to heart function are located; The "Jianli Three Needles Area" located at the lower part of the palm and the "Stomach, Spleen and Large Intestine Area" located directly below the index finger are special acupoints for improving gastrointestinal digestive function and activating other visceral functions. Rubbing these three parts can relieve or eliminate fatigue. When kneading, you can use the thumb of one hand to press the palm of the other hand and the other four fingers to press the back of the hand. Massage and knead the thumb ball clockwise for several times, then massage and knead it counterclockwise for several times to make it warm until it feels slightly painful. Then, change your other hand and massage in the same way. The massage sequence is from left to right for men and from right to left for women.
