Where it is

Two finger-widths lateral to the spine, about level with the ninth thoracic vertebra, below the shoulder blade.

Nearby: Liver on the right, lung bases. Still a back-shu safety point.

Traditionally said to

Back-shu of the Liver. Taught for liver-qi patterns: rib-side tension, eye fatigue, and irritability as classical emotions, not a personality diagnosis.

What people look up

Acupressure

Mild pressure, 30–45 seconds.

When not to press: Right-upper pain with fever or vomiting is medical, not a shu point.

About 30–90 seconds is the usual window, unless the step above is shorter. Stop if pain, dizziness, or anything unusual shows up.

Licensed practice only

Needle depth, angle, electroacupuncture

Textbook language for students. Not instructions. A cun is a body-inch on that person, not a ruler inch. Do not needle yourself.

Depth

Oblique toward the spine, commonly 0.5–0.8 cun.

Angle

Oblique medial.

Electroacupuncture

Introductory charts rarely assign a standard electroacupuncture setting here. Clinics that use current choose frequency and intensity for that person. No milliamp figure is given, because copying one would be misleading.
