2. Dou Eyuan (referred to as Dou Eyuan for short) is a zaju written by Guan Hanqing, a dramatist of the Yuan Dynasty, and it was written in the tenth year of Wanli in the Ming Dynasty (1582). The whole play is 60% off, and it is about a weak widow, Dou E, who was framed by hooligans, beaten by unconscious officials, forced to confess, became a murderer and was sentenced to beheading. Before his execution, Dou E was filled with grief and indignation, and made three vows: blood spilled everywhere, snow fell in June, and there was no drought for three years. Sure enough, Dou E's injustice touched the earth, and the three vows were realized one by one.
