Which CV point is on the abdomen, 7 cun above the umbilicus and 1 cun below the sternocostal angle?

• A. CV 12
• B. CV 13
• C. CV 16
• D. CV 15

Answer: (D)

The distances along the Ren (Conception Vessel) line are set using precise body landmarks, so you locate points by counting cun up from the umbilicus and by notes like the sternocostal angle. The description given—on the abdomen, 7 cun above the umbilicus and 1 cun below the sternocostal angle—matches the position of Ren-15. This point sits on the midline near the center of the chest, just below the sternum and above the diaphragm, at that specific combination of upward distance from the navel and proximity to the sternocostal angle. The other points lie at different vertical positions relative to the umbilicus or sternum, so they don’t fit both landmarks together. So Ren-15 is the correct match.
