1Where is Changqiang?

In the perineal region, below the coccyx.

It lies midway from the coccyx tip to the anus.

Beneath the point

Coccyx · Pubo-analis muscle · Pubo-analis muscle

Our 3D measurement · In our 3D model: midway between the skin at the coccyx tip and an estimated anus position (the model's skin has no anus, so it was estimated from the lower end of the superior rectal artery; 32.7 mm apart), carried down to the skin below. The buttocks are fused in this model, so the point sits 16.3 mm below the straight midpoint of the two — still to be verified.

2How do I find it on my body?

Lie face down or take the knee-chest position.
Locate the tip of the tailbone (coccyx).
The point is halfway between that tip and the anus.
