Which point is crossed by six yang channels?

The point that is crossed by six yang channels is indeed Du14. This point is located on the Du Mai, or Governing Vessel, at the nape of the neck, specifically in the depression below the spinous process of the seventh cervical vertebra. It serves as a key intersection for the six yang channels of the body, which include the Large Intestine, Stomach, Small Intestine, Bladder, San Jiao, and Gallbladder channels.

Du14 is significant in acupuncture and traditional Chinese medicine as it plays a vital role in regulating yang energy and is often used in treatments for conditions related to external pathogens, such as colds and flu, due to its relationship with the yang channels. Its location at the confluence of these channels allows it to promote the circulation of energy and blood throughout the body, making it an essential point for strengthening the yang and enhancing the immune response.

Other points listed, while important, do not have the same level of involvement with the full array of yang channels. Understanding the unique roles and effects of specific acupuncture points, especially in relation to the channels they cross, is critical for effective treatment planning in acupuncture practices.
