An old woman with a bad reputation who constantly causes trouble in the neighborhood. She dragged her whining grandson to Gu Yi's seafood stall and complained about the portion size and content, demanding shrimp. When ignored, she grabbed the cart edge and attempted to extort Gu Yi's family by pretending her leg was broken. The neighbors sided with Gu Yi, knowing Wang A-po's true nature. She left angrily after her scheme failed, slapping her grandson twice.
