1Where is Yinbao?

On the inner thigh, between the gracilis and sartorius muscles.

It is 4 B-cun above the base (upper edge) of the kneecap.

Beneath the point

Sartorius muscle · Gracilis muscle · Adductor magnus

Our 3D measurement · In our 3D model: skin 4 cun (86.6 mm; 1 thigh cun = 21.66 mm) above the patellar base, where the sartorius meets the gracilis.

2How do I find it on my body?

Treat the span between the top edge of the pubic symphysis and the kneecap's base (its upper edge) as 18 B-cun.
Measure 4 B-cun up from the top of the kneecap.
Bend the hip slightly, turn it out and tense the thigh. The sartorius stands out.
Press at its back edge, between it and the gracilis.

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

pubic symphysis: Where the two pubic bones join with cartilage at the bottom middle of the belly; going straight down from the navel you meet it as a hard bony edge. The center of the navel to its upper edge is taken as 5 cun.
adductor magnus: The largest and deepest of the inner-thigh adductor muscles. It brings the leg inward.

Bao means 'to wrap'; the point lies on the inner (yin) thigh. It carries no special category in the classical lists.

From traditional texts — not a claim of effect.
