Divergent collateral of large intestine meridian hand-yangming: it diverges from large intestine meridian at Jianyu acupoint and enters into thoracic cavity from cervical vertebrae then is distributed over lung. Running downward, it passes through diaphragm and is distributed over large intestine.

Lung meridian of hand-taiyin: it starts from middle energizer and runs downward then is distributed over large intestine. Running upward it passes Cardia of stomach and through diaphragm then is distributed over lung, branch is distributed over heart.

Divergent collateral of lung meridian of hand-taiyin: it diverges from lung meridian which is before armpit and runs upward then enters into chest and is distributed over lung. Running downward it passes through diaphragm and is distributed over large intestine.

Small intestine meridian of hand-taiyang: small intestine meridian is the regular meridian which is distributed over small intestine.

From the above 8 meridian and collateral lines, there are 2 meridian vessels, 3 collaterals and divergent collaterals which are distributed over large intestine and they form direct gangway between large intestine and viscera and bowels of spleen and stomach. There are 2 meridian vessels, 1collateral and 1divergent collateral, they form direct gangway between small intestine and viscera and bowels of heart, spleen and stomach. Besides, stomach meridian is associated with small intestine meridian and large intestine meridian direct in meridian and collateral lines.
