1Where is Chengling?

On the head, on the line straight up from the pupil centre, 4 B-cun inside the front hairline.

It is 1.5 B-cun behind Zhengying (GB17), level with BL7.

Beneath the point

Parietal bone · Epicranial aponeurosis

Our 3D measurement · In our 3D model: straight above the centre of the pupil (31.4 mm from the midline), 4 cun above the anterior hairline (measured along the midline skin; 1 cun at the front of the head = 19.66 mm). Same 4-cun level as Tongtian (BL7) measured along the midline; being further from the midline it sits 5.2 mm lower.

2How do I find it on my body?

Have the person look straight ahead and draw a line up from the pupil centre.
Use the front hairline as the base — front to back hairline is 12 B-cun.
On the line, go 4 B-cun past the hairline and press.

Check · it is 1.5 B-cun behind Zhengying.

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

epicranial aponeurosis: A thin, tough sheet of tendon covering the top of the head like a cap, joined to frontalis in front and occipitalis behind. When the scalp moves, it slides with this sheet.
parietal bone: The pair of wide skull bones covering the top and upper sides of the head. They meet along the middle of the crown.
