"竇娥冤" by Hanqing Guan is a Chinese zaju play written during the Yuan dynasty (c. 1241–1320). The story follows Dou E, a young widow wrongly convicted of murder by a corrupt official. After her execution, three supernatural phenomena occur to prove her innocence: blood falling upward, snow in midsummer, and a three-year drought. Her father, now a government official, encounters her ghost and reopens the case to vindicate her and punish the guilty. (This is an automatically generated summary.)
