Which point is located at the highest point of the nasolabial groove?

• A. GV 28
• B. M-HN-20 JĪNJĪN, YÙYÈ
• C. M-HN-14 BÍTŌNG
• D. M-HN-18 JIǍCHÉNGJIĀNG

Answer: (C)

The highest point of the nasolabial groove is at the point known as鼻通 (Bi Tong). This location sits right along the nasolabial fold, at the peak where the crease from the nose toward the mouth forms its most pronounced point. Bi Tong is traditionally used to address nasal issues such as nasal obstruction and congestion, which is why it’s the best pick for this question. The other options are located in different areas (one on the tongue, one on the cheek, and another along a midline facial point), so they don’t correspond to the apex of the nasolabial groove.
