Where it is
Just outside the corner of the mouth, about half a finger from the lip, in line with the pupil when you look forward.
Nearby: Mouth and facial artery branches. Stay on the muscle, light pressure.
Traditionally said to
Local point for mouth deviation and drooling in classical case language. Sudden facial droop is an emergency, not a point to press while you wait.
What people look up
Acupressure
Light circles beside the lip for 20–40 seconds.
When not to press: Sudden face weakness, slurred speech, or a crooked smile of new onset: seek emergency care.
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 0.5–0.8 cun transverse, often toward ST6. Subcutaneous.
Angle
Transverse, laterally toward the jaw muscle, under the skin.
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.
