In the middle era of Ming Dynasty of China (1368 - 1644), Su San, also named Yu-tang Chun, Zhou Yujie, was a daughter of the Mayor of Datong, Shanxi. After both her parents had died, she was abducted and sold to a brothel in Beijing and forced to become a prostitute a few years later. She met Wang Jinglong, the third son of an ousted minister of the Emperor. Su San and Wang Jinghong fell in love immediately. But Wang was expelled from the brothel and had to leave Su San when he had spent all his money. Before long, Su San was sold to a wealthy merchant, Shen Hong, to be his concubine. But Shen Hong was soon poisoned to death by his own wife Pi-shi and her adulterer as he arrived at his home in Hong-tong, Shanxi. Su San was made a scapegoat and convicted of murder by the corrupted official who took bribes from Pi-shi. Su San was put in jail, waiting to be decapitated. Wang had passed the Emperor's examination and became the Patrolling Judge for Shanxi. He appointed Liu as local judge for Su San's case, who acquitted Su San. Wang was finally reunited with Su San after all the ordeals.
