Princess Iron Fan

Princess Iron Fan (simplified Chinese: 铁扇公主; traditional Chinese: 鐵扇公主; pinyin: Tiě shàn gōngzhǔ), also known as Demonic Lady (simplified Chinese: 罗刹女; traditional Chinese: 羅剎女; pinyin: Luó shā nǚ), is a fictional character from the novel Journey to the West. She is the wife of the Bull King and mother of Red Boy. She is a beautiful female demon living in an underground cave awaiting her husband's return, but also angry at him for his affair with a foxy vixen woman, Princess Jade Face. She refused to lend the Monkey King (Sun Wukong) her fan to subdue the flaming mountains.

The pilgrims encounter an extremely hostile range of volcanic mountains and can only pass if the volcanoes become inactive. Her fan, made from banana leaves, is extremely large and has magical properties, as it can create giant whirlwinds. Sun Wukong wants to borrow her fan, but she turns him down as the monkey has been on bad terms with her husband before. Sun Wukong, however, is crafty and has ever better tactics for subduing his enemies. He transforms into a fly and flies into her mouth, down her throat, and into her belly. Once inside, the monkey kicks and punches Princess Iron Fan's guts until she is in so much pain that she gives him a fake fan which intensifies the flames instead of putting them out. Having barely escaped from the fire, Sun Wukong returns, pretending to be her husband through shape shifting and obtains the fan. Soon afterwards, the real husband comes home, angry at what has happened, he pretends to be the Pig (Zhu Bajie) also through shape shifting and offers to carry the big fan. Lost in the moment of victory, Sun Wukong carelessly believes the Bull King and hands over the fan. Later, the Jade Emperor sends his heavenly troops to help Sun Wukong defeat Bull Demon King and Princess Iron Fan for good, and she is forced to give them the real fan.
