a) The meridian starts from the middle jiao (energizer), the portion between 
the diaphragm and the umbilicus of the body, and runs downward to connect with the large intestine. Then it ascends along the upper orifice of the stomach and crosses the diaphragm before pertaining to the Lung.

b) It exits the Lung system (point Zhongfu, LU I) and runs down along the medial Side of the upper arm and in front of the Heart Meridian of Hand-Shaoyin and the Pericardium Meridian of Hand-Jueyin. Then it goes through the cubital fossa and enters cunkou (on the wrist over the radial artery where pulse is felt) along the anterior border of medial side of the forearm. It continues to run along the thenar eminence and the thenar border and arrives at the medial Side of the thumb tip (point Shaoshang, LU 11).

c) A branch starts from Lieque (LU 7) and runs along the radial side to the tip of the index finger, where it links with the Large Intestine Meridian of Hand-Yangming.
