In our body we have two very
important meridians, one is called Ren Mai (the Control Meridian) and
the other is called Du Mai (the Function Meridian). The Chi of the Yin
belongs to the Ren Mai and the Chi of the Yang belongs to the Du Mai.
The Chi of the Yin flows through the Ren Mai, from the Tian Chi reaches
the Tan Tien in front of the body. The Chi of Yang flows through the
Du Mai from the Tan Tian to the Tian Chi behind the body.
