三藩之乱
Chen Yuanyuan (1624–1681) was a courtesan who lived during the late Ming and early Qing dynasties. She was the concubine of Wu Sangui, the Ming dynasty general who surrendered Shanhai Pass to the Manchu Qing dynasty, and later rebelled in the Revolt of the Three Feudatories. Chen's life and relationship to Wu later became the subject of a number of popular stories and legends, many of them focusing on her supposed role in Wu's fateful decision to defect to the Qing, thereby sealing the fate of the Ming dynasty.
