Which acupuncture point is located on the upper abdomen 6 cun above the umbilicus, 0.5 cun lateral to the midline?

• A. REN-14
• B. KD 20
• C. KD 21
• D. KD 19

Answer: (C)

The key idea is precise abdominal point location using cun measurements and a small lateral offset from the midline. On the abdomen, specific points are positioned a certain number of cun above the navel and either on the midline or 0.5 cun to the side. KD-21 sits on the Kidney channel in the upper abdomen, 6 cun above the umbilicus and 0.5 cun lateral to the midline. That exact combination of height and off-midline position matches the description. The midline point at the same height would be Ren-14, which is on the center line, not 0.5 cun to the side. Points KD-20 and KD-19 are located 5 cun and 3 cun above the umbilicus, respectively, both also 0.5 cun lateral to the midline, so their vertical positions don’t align with the given description.
