Which acupuncture point lies on the upper abdomen 6 cun above the umbilicus?

• A. REN-14
• B. KD 20
• C. KD 21
• D. KD 22

Answer: (C)

Understanding how to locate points on the abdomen using the cun measurement is essential. KD 21 is placed on the midline of the upper abdomen, exactly 6 cun above the umbilicus. This precise vertical position aligns with the Kidney channel’s path up the abdomen toward the chest, making KD 21 the correct choice for a point described as being on the upper abdomen at that distance above the navel. The other named points are not located at this same midline upper-abdominal position, so they don’t fit the described location.
