Cun (Body Inch)
寸cùn · Channels & Points
The Cun is a proportional unit of measurement used to locate acupuncture points, defined relative to the individual patient's own body rather than a fixed length. For example, the width of the thumb at the knuckle is one cun, and the width of the four fingers together is three cun.
