1Where is Tianfu?

Front-outer upper arm, just outside the outer border of the biceps brachii.

It is 3 cun below the anterior axillary fold, one third of the way down to the elbow crease (a 9-cun span).

Beneath the point

Biceps brachii · Humerus

Our 3D measurement · In our 3D model: 6.00 cun above Chize (LU5) = 3 cun below the anterior axillary fold (1 upper-arm cun = 21.8 mm: 9 cun from the anterior axillary fold, the lower edge of the pectoralis major, to the elbow crease — the same cun as LI13 and LI14), 3.6 mm lateral to the biceps brachii.

2How do I find it on my body?

With the arm by your side, put a finger on the front end of the armpit fold (anterior axillary fold).
Find the level of the elbow crease, where Chize (LU5) lies.
Divide the distance into thirds and take the upper mark.
At that height, feel the outer edge of the biceps and press the soft tissue just outside it.

📖 Words explained

anterior axillary fold: The fold at the front of the armpit with the arm at the side, made by the lower edge of pectoralis major. Its top end is a starting mark for measuring upper-arm points.
biceps brachii: The 'biceps' at the front of the upper arm; its two heads join on the radius to bend the elbow and turn the palm up. Bend the arm and you feel its thick tendon in the crook of the elbow.
