On the abdomen, 2 cun lateral to the midline and 6 cun superior to the umbilicus, level with REN-14, which acupuncture point is located here?

• A. ST 18
• B. ST 19
• C. ST 10
• D. ST 11

Answer: (A)

This spot is on the Stomach channel in the chest, identified by two key cues: it sits 2 cun to the side of the midline and at the level aligned with Ren-14. That horizontal level corresponds to the chest’s fourth intercostal space, which places the point in the mammary region on the chest rather than on the abdomen. In other words, the position described matches the chest point that lies in the 4th intercostal space, 2 cun lateral to the midline, commonly referenced as ST-18. The other listed points lie in different intercostal spaces or higher/elsewhere on the body, so they wouldn’t fit this exact coordinate.
