Which point is known as the Exit point?

The point known as the Exit point is LI-6, not LI-20. Exit points are specific acupuncture points that serve as exit pathways for Qi and are responsible for the distribution of energy to the Yang channels. In this case, LI-6, located on the Large Intestine meridian, acts as an important exit point for the channel, facilitating the flow of Qi.

When considering other points, LI-20, located at the nasolabial groove, is primarily used for nasal issues and sinus conditions rather than serving as an exit for channel Qi. This differentiates its function from that of LI-6. Similarly, LI-18, located along the neck, does not have the same role as an exit point; rather, it is commonly used for throat conditions. LI-4 is primarily known for its influential role in pain relief and regulating Qi but is not classified as an exit point either.

Thus, recognizing LI-6 as the exit point emphasizes the importance of understanding the specific functions of acupuncture points, especially in the context of channel physiology and the flow of Qi within traditional Chinese medicine.
