Where it is
At the inner end of the knee crease, just above the tendon you can feel when the knee is bent, in a hollow.
Nearby: Inner knee. Similar neighborhood to KI10 but slightly different tendon relationship. Don’t press a swollen joint.
Traditionally said to
He-sea and water point of the Liver. Taught for damp-heat in the lower burner and for inner-knee pain, in textbook language.
What people look up
Acupressure
Knee bent, press the hollow for 30–45 seconds.
When not to press: Skip an injured or hot knee.
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
Common textbook range: about 1–1.5 cun perpendicular.
Angle
Perpendicular, at the medial end of the popliteal crease.
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.
