Legend has it that more than 2,000 years ago, Emperor Wudi (156-87 BC) of the Western Han Dynasty was very depressed over the death of his favorite concubine. To help him get over his sadness, a minister made a puppet out of cotton and silk in the likeness of the concubine and projected its shadow on a curtain for the emperor to see. The show brought the emperor some consolation. He somehow believed the shadow was his lover's spirit. This is thought to be the beginning of the shadow play puppetry.
