Which points form the meeting points at GB-20?

The correct answer highlights the specific channels and extraordinary vessels that converge at Gallbladder 20 (GB-20), which is located at the nape of the neck and is an important point for both the Gallbladder meridian and the Yang Wei vessel.

GB-20 is known to be a meeting point for the Gallbladder (GB), the San Jiao (SJ), the Yang Qiao (yang heel), and the Yin Qiao (yin heel) channels. This convergence is significant because it allows GB-20 to play a crucial role in the regulation of yang energy in the body and in addressing pathologies associated with both the head and neck area.

The positioning of GB-20 makes it vital for treating conditions like headaches, neck stiffness, and conditions tied to excess yang energy. Additionally, the connection with Yang Qiao and Yin Qiao meridians emphasizes its function in balancing the energetic qualities in the body, particularly with issues related to the eyes and head.
