The Lung meridian goes from the chest to the hand and circulates on the inner anterior edge of the upper arm, with the main trunk reaching the end of the thumb and the branch meridian terminating at the end of the forefinger, where it meets the Hand Yangming Large Intestine meridian. The starting point of the Hand Taiyin Lung Meridian is the Zhongfu point and the ending point is the Shaoshang point. The Lung meridian circulates in the body from the middle jiao down to the large intestine, then up to the stomach and through the diaphragm into the lungs. It then travels from the chest to the outside of the body, through the armpit to the upper arm, along the inner anterior edge of the upper arm, past the elbow, to the forearm, all the way down through the inches of the mouth to the big fishbow, along the radial side of the big fishbow straight to the end of the thumb. The branch of the Lung meridian, which branches off from the position at the back of the wrist (the Lechu point), follows the radial edge of the index finger to the end of the index finger, where it intersects the Hand Yangming Large Intestine meridian.
