1Where is Zigong?

On the front of the chest, on the midline over the breastbone, level with the second intercostal space.

Beneath the point

Body of sternum · Costal cartilage of second rib · Costal cartilage of third rib · Costal cartilage of second rib · Costal cartilage of third rib

Our 3D measurement · In our 3D model: on the skin over the sternum, at the height of the second intercostal space read at the edge of the sternum (left–right difference 0.2 mm, averaged) and carried to the midline.

2How do I find it on my body?

Find the horizontal ridge near the top of the breastbone (the sternal angle). The second rib attaches here.
The rib space just below it is the second intercostal space.
Press the middle of the breastbone at that height.

📖 Words explained

intercostal space: The gap between two ribs, felt with a fingertip as a slight groove between bone and bone. It is named after the rib above it (the gap below the first rib is the first intercostal space).
body of sternum: The long middle part of the breastbone. Where it meets the manubrium there is a raised horizontal ridge (sternal angle), and the xiphoid process hangs from its lower end.
costal cartilage: The firm cartilage that joins the front end of a rib to the breastbone. It is a little softer and more bendy than bone, so the chest can expand when we breathe.
sternal angle: The slight horizontal ridge where the manubrium meets the body of the breastbone; slide a finger down from the notch at the base of the neck and it catches on it. The second rib attaches right beside it, so it is the starting mark for counting ribs.

3Before you press

⚠ Do not press when

Avoid broken or swollen skin and press only to a comfortable level.

4How has it been used traditionally?

The name means 'purple palace' (not the word for 'womb'). It carries no special category in the classical lists.

From traditional texts — not a claim of effect.
