How many cun are measured from the navel to the pubic symphysis?

The distance from the navel to the pubic symphysis is standardized as approximately 5 cun in traditional Chinese medicine and acupuncture. The cun measurement is a unit of distance commonly used in acupuncture to establish points on the body and is based on the anatomical proportions of an individual. The navel is a central reference point, and understanding this specific measurement aids practitioners in locating acupuncture points accurately.

The reason this measurement is important is because it helps in the consistent application of acupuncture techniques and in the assessment of various conditions that may arise in the lower abdominal region. By knowing that this distance is 5 cun, practitioners can confidently use this knowledge when assessing and treating patients.
