As for the eight special meridians, they spread throughout the body. The most two important special meridians were the Ren Du Er Mai.
The position of the Ren Du Er Mai is in the central axis line of a person, and will be seen as a straight line from the front.
The Ren vein is located in the front, while the Du vein is in the back. The two lines circle into a bundle in a person’s body, passing through the Dan Tian and Hui Yin. Like two ropes that passed through a person’s crotch, they held up a person’s body.
