Because children sometimes do not have good spleen and stomach function, they need to improve their spleen and stomach function by applying foot massage or moxibustion. Parents can use the following methods to locate the exact location of the third mile of the foot in children. First, parents can locate the child’s patella. Place the child’s fingers on the lower edge of the patella, including the child’s index finger, middle finger, ring finger, and little finger, which together are about three inches wide. The child’s fingers are placed horizontally from the lower edge of the patella, which is about three inches. At the lateral edge of the lower leg, about one inch from the tibia, is the exact location of the three li of the foot. Parents must pay attention to the fact that the positioning of the foot three miles and three inches is based on the child’s fingers. It cannot be according to the width of the adult’s finger, which is often a little too wide.
