Which point is above the chin, in the centre of the mentolabial groove?

• A. CV 22
• B. CV 23
• C. CV 24
• D. GV 1

Answer: (C)

The midline Ren (Conception Vessel) points near the mouth are arranged from chin upward along the center of the face. The point that sits in the center of the mentolabial groove—right above the chin in the small depression between the lower lip and the chin—is CV-24, known as Chengjiang. This spot is exactly where the question describes, making it the correct location. The other options lie in different regions along the front midline or elsewhere on the body and do not correspond to the center of the mentolabial groove.
