Iron-Crutch Li (铁拐李 418-326BC), the leading figure of the Eight Immortals, from Sichuan, representing yin-metal in Five Agents and ☱ (兌) in Eight Trigrams. According to Daoist classics, Crutch Li was an impressive-looking guy and spent decades meditating in a mountain cave. One day he decided to tour around the world, so he left his body in the cave in a vegetative state cared for by his disciple. A few days later, the disciple was urgently called home to deal with some urgent matters. When Crutch Li returned the cave, he found his body was no longer usable so he got into a fresh corpse of a bagger staved to death and with that unsightly appearance he entered the immortal realm. In the popular culture, Crutch Li forever holds a metal crutch and carries a huge bottle gourd in his back. The Crutch both serves as his magic wand and his personal vehicle, while the gourd filled with plasters to cure rheumatoid arthritis, a disease suffered by the bagger as the result of sleeping outdoors.
