Cai's mother-in-law is kind-hearted and subsidizes him to go to Beijing to take the exam. However, the fate of poor Dou E is even more tragic. Her husband died soon after she got married. Although her mother-in-law didn't blame her, they supported each other and lived alone. But after all, there are no men at home and they will be bullied. Dou E was attracted by a broken donkey named Zhang Er. Threatened and lured Cai's mother-in-law to marry, but Cai's mother-in-law just wouldn't.
So Zhang donkey went to buy arsenic, trying to poison Cai's mother-in-law, but not his father. Zhang Luer became angry from embarrassment, sued Dou E to the government and colluded with the county magistrate to extort a confession by torture. When refusing to plead guilty, they threatened to torture Cai's mother-in-law. Cai's mother-in-law was distressed and pleaded guilty with tears. On the day of execution, Dou E made three poison oaths.
First, if she is wronged, then after the executioner cuts off her head, the blood will fly to the white silk hanging high; Second, if she is wronged, it will snow in June after her death; The third is that if she is wrong, it will be dry for three years after her death. Dou E was undoubtedly wronged, so all three poison oaths were realized. But these people are not wronged. When being molested by a donkey, nobody wants to stand up and stop him. When Dou E was wronged, no one wanted to speak out and be fair. So there will be a three-year drought, which is purely their own fault.
