The nose belongs to the Lung Meridian of Hand-Taiyin (as stated in *Suwen*: "The West corresponds to white, its qi communicates with the Lung, and it opens into the nose"). It is also the convergence of the Yangming Meridians of Hand and Foot and the Du Mai (as stated in *Suwen*: "In the second day of Cold Damage, the Yangming channel is affected. Yangming governs the flesh, and its vessels flank the nose").
