Yilin Verse
金城鐵郭，上下仝力，政平民歡，寇不敢賊。
A fortress of metal, walls of iron; above and below unite their strength. Governance is just, the people rejoice; bandits dare not plunder.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Doubled fire meets fire and thunder together: brilliance forges an impenetrable order. Walls of metal, ramparts of iron — ruler and subjects unite their strength. Governance is fair and the people rejoice; invaders dare not strike. The 'golden city, iron walls' is a classical metaphor for a state made invincible through internal unity rather than mere fortification. When law is clear and administration just, the people's loyalty itself becomes the strongest defense. From The Clinging to Biting Through, fire's clarity joins thunder's decisive force. Lightning and thunder combined illuminate and punish in a single stroke. The hexagram of law enforcement finds its highest expression not in severity but in the justice that makes walls unnecessary because no enemy would dare approach.
