The distribution of the twelve meridians follows a certain rule. The rule varies according to the running routes of the meridians. Head and face: The hand-yangming meridian and foot-yangming meridian run over the face and the forehead; the hand-shaoyang meridian and foot-shaoyang meridian run along the lateral sides of the head; the foot-taiyang meridian runs over the vertex and the nape; the hand-taiyang meridian runs over the cheeks.

The four limbs: The three yin meridians of the hand and the three yang meridians of the hand run along the upper limbs; the three yin meridians of the foot and the three yang meridians of the foot run along the lower limbs. The yin meridians run along the medial side of the four limbs while the yang meridians run along the lateral side of the four limbs. The distributing order of the yang meridians is like this: the yangming meridians are distributed over the anterior border (lateral side of the thumb), the taiyang meridians are distributed over the posterior border (the lateral side of the small finger), and the shaoyang meridians are distributed along the midline.

The distributing order of the yin meridians is like this: the taiyin meridians are distributed over the anterior border, the shaoyin meridians are distributed over the posterior border and the jueyin meridians are distributed along the midline. Over the lower part of the lower limbs, the jueyin meridians are distributed over the anterior border, the taiyin meridians are distributed along the midline. The two meridians cross about eight cun above the tip of internal malleolus, then the taiyin meridian runs to the anterior border and the jueyin meridian runs to the midline.

The trunk：The three yang meridians of the hand run over the scapula; among the three yang meridians of the foot, the yangming meridian runs over the front (the chest and abdomen), the taiyang meridian runs along the back and the shaoyang meridian runs along the side of the body; the three yin meridians of the hand all emerge from the armpit; the three yin meridians of the foot all run over the chest and abdomen. The meridians running on the chest and abdomen from the medial to the lateral are foot-shaoyin meridian, foot-yangming meridian, foot-taiyin meridian and foot-jueyin meridian respectively.v
