The Twelve Metal Colossi (Chinese:十二金人) were twelve metal statues cast after 221 BCE by the order of Qin Shi Huang, the first Emperor of China. After defeating the other six Warring States during Qin's wars of unification, Qin Shi Huang had their weapons collected and melted them down to be recast as bells and statues. Particularly noteworthy among them were twelve human statues, each said to have weighed a thousand "dan" (picul).
