With the eyes looking directly forwards, which point is positioned directly below the pupil between the eyeball and the infraorbital ridge?

• A. St 2
• B. St 1
• C. Li 20
• D. St 3

Answer: (B)

The main idea here is using facial landmarks to locate acupuncture points. When the eyes look straight ahead, the center of the pupil defines a vertical line that lands in the infraorbital region directly below the pupil. That spot sits just under the eye, in the infraorbital margin (near the infraorbital foramen), which is exactly where ST 1 is described to be. So the point directly below the pupil between the eyeball and the infraorbital ridge is ST 1.

The other sites are in different parts of the face: one is near the side of the nose, another is farther down on the cheek. They don’t align with the vertical line from the pupil to the infraorbital margin, so they don’t match the described position.
