The Du channel starts midway between the tip of the coccyx bone and the anus with patient lying prone. It then flows upward inside the spinal column to the nape of the neck, and ascends to the vertex. Along the forehead, it descends to the nose bridge, then to the lips. Ending at the labial frenulum inside the upper lip.

Spinal Hua Tuo Points
These classic points are located just half a cun, or human inch (the distance across the widest part of the patient's thumb) bilateral to Du Mai (GV) (midline over the vertebral spinous process) from T1 through L5. Classically there are 17 pairs of points (34 points total) attributed to Hua Tuo. Within the last 2,000 years, these points have extended both upward through the cervical spine and downward across the sacrum. The points in the cervical and sacrum are simply known as jia (lining) ji (spine).
