Cun - Meaning and Measurement

Cun Measurement Information for TCM and Acupressure Gauging Dimensions

The measure "cun" (tzun - pronounced closer to 'zun') is sometimes thought of in English as an "inch" in English. However, in dealing with acupuncture and acupressure, cun is a relative term. Each person has different body dimensions; the measurement of cun is defined for each person as it relates to that individual's body proportions and size.
