What is the location of Du-16?

Du-16, also known as Fengfu, is located immediately below the external occipital protuberance. This point is significant in traditional Chinese medicine as it is an important point for accessing the energy of the Du meridian and is often used to address issues related to the head and neck.

The external occipital protuberance is a bony prominence on the back of the skull, and the precise location of Du-16 helps practitioners leverage its anatomical features to effectively treat conditions such as headaches, dizziness, and neck stiffness. Understanding its location relative to nearby anatomical landmarks is essential for proper needling and achieving the desired therapeutic effect.

In contrast, the other options describe locations that do not accurately correspond to the established anatomical definition of Du-16. For instance, being "above" or "at the midpoint" of the skull implies a different relationship to the external occipital protuberance and would not provide the same clinical utility for treating conditions associated with this acupuncture point. Similarly, the forehead location is unrelated to Du-16, which is situated more posteriorly along the midline of the body.
