A quiet but important point on the upper chest, Xuanji (CV-21) opens the airway, eases breathing and clears obstructions from the throat and chest. Sitting just below the throat on the breastbone, it belongs to a cluster of powerful Conception Vessel (CV) points that govern the flow of Qi through the upper body.
Contraindications
As with all points on the sternum, care is needed with needle depth and direction — the needle should be kept close to the bone and directed downward along the sternum, never angled inward toward the chest cavity.
Name & story
The name 璇玑 Xuanji carries a beautiful, almost celestial meaning — it refers to the second star of the Big Dipper constellation, one of the pivoting stars that ancient Chinese astronomers used to mark the turning of the heavens. There is something poetic in placing this name on the upper chest: just as the star Xuanji sits near the axis of the sky, this point sits near the centre of the upper body, where breath and Qi rotate and circulate. It marks a place where the flow of life pivots — where the throat meets the chest and where air descends to become nourishment.
Point family & character
Xuanji (CV-21) belongs to the Conception Vessel (CV), the great Yin vessel that runs along the front midline of the body. It sits between its famous neighbours — Tiantu (CV-22) at the base of the throat above it and Shanzhong (CV-17) on the chest below — and shares their work of governing the Qi of the Lungs and throat.
Five-element dynamics
In Chinese medicine, the chest is the domain of the Lungs and the Heart, and the Conception Vessel threads through it carrying Yin and Qi upward and downward. CV-21 sits in the upper chest, close to where the throat opens into the lungs. Its position makes it naturally suited to descending rebellious Lung Qi — the kind that rises up as cough, wheezing or the suffocating feeling of something stuck in the throat. When the Qi flows smoothly downward through this point, the chest opens, breathing deepens and the throat clears.
Location
On the anterior midline, on the sternum, 1 Cun below Tiantu (CV-22) — or equivalently, in the centre of the chest at the level of the first intercostal space. It sits between CV-22 (the hollow at the base of the throat) above and CV-20 below.
Anatomy & fascia
The point lies on the sternum (breastbone), in the region of the upper chest, between the sternal angle and the jugular notch.
Needling
The needle is inserted subcutaneously, directed downward along the sternum (in a diagonal or transverse direction). As with all sternal points, the needle should stay close to the bone and not be angled inward toward the chest cavity.
The golden tip
If you feel chest tightness, a tight throat or find it hard to take a full deep breath, try gently pressing the centre of your upper breastbone — just below the little hollow at the base of the throat. Hold steady, gentle pressure for a minute or two and breathe slowly and deeply. This simple touch can help Qi move through the chest again. It is safe to use at home for everyday tension and mild discomfort.
