1Where is Tianquan?

Front of the upper arm, 2 cun below the front armpit fold, between the long and short heads of the biceps brachii.

Beneath the point

Long head of biceps brachii · Short head of biceps brachii · Humerus

Our 3D measurement · In our 3D model: 2 cun (43.6 mm; 1 upper-arm cun = 21.79 mm) below the front armpit fold, in the groove where the long and short heads of the biceps brachii meet.

2How do I find it on my body?

With the arm by your side, find the end of the front armpit fold.
Go 2 cun down (two ninths of the 9-cun span from that fold to the elbow crease).
Press into the groove between the two heads of the biceps.

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

short head of biceps brachii: The inner head of biceps. It starts from the coracoid process of the shoulder blade.
long head of biceps brachii: The outer head of biceps. Its tendon passes through the shoulder joint to attach above the socket of the shoulder blade.
