Which CV point sits on the midline of the sternum at the level with the fourth intercostal space?

• A. CV 16
• B. CV 18
• C. CV 17
• D. CV 19

Answer: (C)

Ren-17, also called Shanzhong, sits on the midline of the sternum at the level of the fourth intercostal space. This location places it at the central chest along the Conception Vessel, making it the key point for regulating qi in the chest and addressing chest fullness, coughing, and related issues. The other options correspond to different intercostal levels along the sternum, so they do not match the described midline chest position at the fourth intercostal space.
