What are the three depths for the needle techniques of "Setting the Mountain on Fire" and "Penetrating Heaven-Coolness"?

"Setting the Mountain on Fire" and "Penetrating Heaven-Coolness" are acupuncture techniques that utilize specific needle depths to achieve their therapeutic effects. The correct answer indicates the needle depths of 0.5, 1.0, and 1.5 cun, which correspond to the techniques' intended stimulation levels and effective engagement with the body's energetic pathways.

In traditional Chinese medicine, different needle depths can elicit varying responses from the body. The choice of 0.5, 1.0, and 1.5 cun provides practitioners with a range that allows for both superficial and deeper stimulation, which can be critical depending on the patient’s condition, the specific acupuncture point being targeted, and the desired outcome of the treatment.

These depths are also significant in maintaining patient comfort while ensuring that the therapeutic action reaches the appropriate layers of tissue to influence the flow of Qi and blood effectively. The ability to adjust the depth within this range helps address individual patient variations and enhances the overall efficacy of treatment.
