Jing-Luo System
Traveling course of the regular meridian
It starts from the chest, homes to the pericardium, descends to the abdomen, and connects the upper, middle, and lower Jiao.
One branch runs along the chest, emerges from the costal region at a point 3 cun below the anterior axillary fold, ascends to the axilla, runs down between the Lung and Heart Meridians to the middle finger, and ends on the radial side of the tip at PC 9 Zhongchong 
.
Another branch arises from the palm at PC 8 Laogong 
, and runs along the ring finger to the ulnar side of the tip to TE 1 Guanchong 
to link with the San Jiao Meridian.
Traveling course of the divergent meridian
It diverges from the regular Pericardium Meridian at the upper arm, at a point 3 cun below the axilla and 3 cun below GB 22 Yuanye 
, enters the chest, and connects with the san Jiao or triple burner. A branch ascends along the throat and emerges behind the ear, and finally joins the San Jiao Meridian.
Traveling course of the collateral
It separates from the regular Pericardium Meridian at PC 6 Neiguan 
, 2 cun above the transverse crease of the wrist, travels between the two tendons, ascends along the regular meridian to the pericardium, and connects with the heart system.
The muscle region
It starts at the middle finger, runs together with the muscle region of the Lung Meridian to knot at the medial aspect of the elbow, ascends the medial side of the upper arm to knot again at the axilla, and descends to disperse into the anterior and posterior regions of the hypochondrium. A branch enters the hypochondrium, spreads into the chest, and binds at the diaphragm.
