Which points meet at SJ-20?

SJ-20, also known as "Jiaosun" or "Ear Gate," is a point located in the region of the ear and is significant in Traditional Chinese Medicine (TCM). It serves as a meeting point for the San Jiao (SJ), Small Intestine (SI), and Gallbladder (GB) meridians.

In TCM, meeting points are anatomical locations where multiple meridians converge, which can enhance the therapeutic effects of acupuncture in treating various conditions associated with those pathways. SJ-20 is particularly important for addressing issues related to the ear, as well as symptoms in the areas associated with the pathways of the SJ, SI, and GB. This unique convergence allows practitioners to utilize SJ-20 effectively for treating conditions such as tinnitus, earaches, and neurological disorders.

The selection of SJ, SI, and GB as the correct answer highlights the significance of this point in the broader context of meridian theory, showing how interconnected the energy flows are in the body, and how treating one area can impact several related systems.
