Heart-Protecting Mirror is a metal element near the center of the chest. It can strengthen local protection and create a visual focus, but it is distinct from the two larger Mingguang chest discs and from Chest Armor or Body Armor as a whole. Some Mingguang arrangements may omit it.
Protection and Rigging Hub
When present, its rear surface can serve as a central attachment node. Two lateral cords may extend toward a central bronze ring on the back. An upper cord may connect toward the collar or neck structure, while a lower cord may connect to the Belly Swallow. The front center can therefore combine protection with vertical and lateral rigging.
Front-to-Back Connection Network
The rear central element may be a bronze ring, metal disc, or in some forms a rear protective mirror. During wearing, the Heart-Protecting Mirror may also become structurally linked with the two separate Mingguang chest discs, upper collar, and Belly Swallow, forming a front-to-back tension and suspension network. Physical connection does not make these components one identity.
Historical Visual Evidence and CG Interpretation
Water-and-Land paintings sometimes show a bronze ring at the usual front-mirror position. If position and cord network remain while a ring replaces the mirror, the structural-hub role may be more fundamental than one exact disc form. CG interprets the element as potentially combining protection, visual focus, and rigging. This does not claim every historical mirror was primarily a rigging hub or used one cord arrangement.
