The Kanji: 璧 (Heki)
The kanji 璧 (read as heki) means a "round flat jewel" or a "disc-shaped ritual jade object." It is composed of the radical 玉 (tama, meaning "jewel" or "gem") which clearly indicates its precious, jewel-like nature, combined with the phonetic component 辟. In ancient China, such jade discs were highly valued ceremonial objects, often symbolizing perfection and authority.
