FAQ

1Where is Zhizheng?

Back-inner forearm, 5 cun above the back wrist crease, between the inner border of the ulna and the flexor carpi ulnaris muscle.

It is 1 cun on the wrist side of the midpoint between SI5 and SI8.

Beneath the point

Ulna · Flexor carpi ulnaris

Our 3D measurement · In our 3D model: 5 cun (107.4 mm) above the wrist crease, between the ulnar edge of the ulna and the flexor carpi ulnaris (4.2 mm apart).

2How do I find it on my body?

Find the midpoint of the line from SI5 to SI8 (6 cun from the wrist).
Move 1 cun back toward the wrist.
Press into the groove between the edge of the ulna and the muscle beside it.

What is a “cun”?

A cun is a body-scaled unit of length. The precise way is to divide a bone length into equal parts (proportional bone cun); finger widths are a quick estimate.

📖 Words explained

flexor carpi ulnaris: A muscle along the little-finger edge of the palm side of the forearm, running to the pisiform. It bends the wrist and tilts it toward the little finger.
wrist crease: The horizontal crease that forms at the wrist when it is slightly bent. There is one on the palm side and one on the back, and they are starting lines for measuring arm points.
