1Where is Binao?

Outer side of the upper arm, just in front of the front edge of the deltoid.

It is 7 cun above LI11 (Quchi).

Beneath the point

Deltoid · Humerus

Our 3D measurement · In our 3D model: 7.09 cun from Quchi (LI11), just in front of the most anterior edge of the deltoid at that level. 1 upper-arm cun = 21.8 mm: the standard 9 cun from the anterior axillary fold (lower edge of the pectoralis major) to the elbow crease — the same cun as LU3 and LU4.

2How do I find it on my body?

Tense the arm so the deltoid stands out.
Trace its front edge down to where the muscle narrows.
Find the height: divide elbow crease to front armpit fold into 9 parts and go up 7, which is two parts below the armpit fold.
Press just in front of the edge at that height.

3Before you press

⚠ Do not press when

Avoid broken, bruised or swollen skin and press only to a comfortable level.
Acupressure is not a substitute for medical care.

4How has it been used traditionally?

Traditionally pressed for the shoulder and upper-arm region.

From traditional texts — not a claim of effect.

5Alternative location

Chinese standard (2021) differs · China's 2021 standard takes the front edge of the deltoid on the LI11–LI15 line as the main reference and gives 7 cun only as an approximate height.
