In the legend Journey to the West, the Monkey King Sun Wukong goes to the underwater kingdom of Ao Guang, the Dragon King of the East Sea, looking for a magic weapon to match his strength and skill.
All of the sea's magic weapons — swords, spears, and halberds weighing thousands of pounds each — fail to meet his standards. The dragon queen suggests to her husband that they give Sun an iron pillar used by Yu the Great to measure the depths of the ocean in ancient times.
The ancient shaft had started producing heavenly light days prior, suggesting that the monkey is fated to own it.
The pillar of black iron is twenty feet in height and the width of a barrel. But when Sun lifts it and suggests that a smaller size would be more manageable, the staff complies with his wishes and shrinks.
This is when Sun sees that the weapon is banded with a gold ring on each end, as well as the inscription along the body reading "The Compliant Golden-Hooped Rod". This indicates that the staff follows the commands of its owner, shrinking or growing to his whim and makes copies of itself.
Inspired by the Asian classic, this handmade leather bracelet features a dragon wound around a metal pillar.
