Ruyi Jingu Bang

The Stabilizing Pillar of the Sea

Sun Wukong’s shape-shifting staff, once Yu the Great’s sea-settling iron, weighing 13,500 jin.

The Ruyi Jingu Bang was originally divine iron refined by Lord Lao and used by Yu the Great as a sea-settling pillar before it rested at the bottom of the Eastern Sea. Sun Wukong claimed it, learned to shrink or swell it at will, and made the 13,500-jin staff the very emblem of the Monkey King.
