Wu Dalang (Chinese: 武大郎; pinyin: Wǔ Dàláng), also translated as Wu the Elder, is a major character in the classic Chinese novel The Plum in the Golden Vase, and a minor character in the Water Margin, another classic. In both novels, he is murdered by his adulterous wife Pan Jinlian. A well-known figure in Chinese culture, he represents the quintessential cuckold.
Wu Dalang and Pan Jinlian, as depicted in these two novels, are fictitious. The real people were nothing like the characters in these stories.
