1Where is Chengfu?

Buttock, at the midpoint of the gluteal fold.

The fold is the crease between the buttock and the thigh.

Beneath the point

Long head of biceps femoris · Gluteus maximus muscle · Semitendinosus muscle

Our 3D measurement · In our 3D model: where the back midline of the thigh meets the buttock crease (the height where the skin dips in most).

2How do I find it on my body?

Lie face down or stand.
Follow the crease under the buttock (gluteal fold) from its inner to its outer end.
Press its midpoint.

📖 Words explained

long head of biceps femoris: The head of biceps femoris that starts from the sitting bone (ischial tuberosity).
sciatic nerve: The thickest nerve in the body. It comes out deep in the buttock (below piriformis) and runs down the middle of the back of the thigh, splitting above the knee into the tibial and common fibular nerves.
semitendinosus: A muscle on the inner back of the thigh. Its lower half is a long tendon, hence its name; bend the knee and the thin tendon stands out like a cord on the inner side of the back of the knee.
gluteal fold: The horizontal crease where the buttock meets the back of the thigh.
gluteus maximus: The large, thick muscle that forms the buttock. It swings the leg back and gives power for climbing stairs and standing up.

3Before you press

⚠ Do not press when

The sciatic nerve runs deep here.
Stop if tingling shoots down the leg.
Avoid broken or swollen skin and press only to a comfortable level.
Acupressure is not a substitute for medical care.

4How has it been used traditionally?

The name means 'receiving support' — holding up the weight of the trunk. The Zhenjiu Jiayi Jing gives Rouxi, Yinguan and Pibu as alternative names.

From traditional texts — not a claim of effect.
