Dou E's Injustice "portrays a tragic story in the social context of the Yuan Dynasty through the brushstrokes of Guan Hanqing. Dou E's life was full of ups and downs, from being sold to Granny Cai by her father for debt, to relying on Granny Cai for survival after her husband's death, to being framed by Zhang Luer and ultimately dying unjustly. Her experiences reflected various injustices in society at that time. From the perspective of modern criminal law, behaviors such as Granny Cai's high interest loans, Dou's father selling his daughter, Zhang Wu'er's attempted poisoning, and the corrupt and unjust behavior of Governor Tao Qian all involve different legal issues. Granny Cai may be charged with high interest loan transfer, Dou's father is suspected of child trafficking, and Granny Cai is suspected of buying abducted children. Zhang Lu'er's behavior involves the imaginative competition between attempted intentional homicide and negligent homicide. The behavior of Governor Tao Qian is suspected of bribery and torture to extract confessions. Dou E's injustice can be corrected and compensated through the judicial supervision procedure and the National Compensation Law under the modern legal system. Dou E's Injustice "is not only a literary work, but also a valuable case study in legal education, demonstrating the progress of law in pursuing fairness and justice and protecting women's rights.
