Which acupuncture point is located in the nasolabial groove at the level of the midpoint of the lateral border of the ala nasi?

• A. Li 20
• B. St 1
• C. St 3
• D. St 2

Answer: (A)

LI-20, also known as Yingxiang, is located in the nasolabial groove at the level of the midpoint of the lateral border of the ala nasi. This spot sits right beside the nostril along the crease that runs from the nose to the cheek, which is exactly why it’s described as being in the nasolabial groove at that specific level. The other points listed are placed in different parts of the infraorbital region or cheek and do not lie in that nasolabial crease, so they don’t match the location described.
