In ancient times, Cao Zhuang was an official in Chu and was loyal to the country. Cao Zhuang went home to take care of her mother because she was old and ill. Cao Zhuang has a wife, Shi Jiao, who is not virtuous. She is shrewd by nature and often abuses her mother-in-law. One day, Shi Jiao ate and drank at home while Cao Zhuang was away, regardless of whether her mother-in-law was hungry or not. Cao's mother was so hungry that she asked Jiao for food, but she was beaten and scolded by Jiao. After Cao Zhuang returned home, Cao's mother complained to her son, and Cao Zhuang angrily accused Shi Jiao, who importuned and made Cao Zhuang angry and wanted to go to Shi Jiao. Seeing that something was wrong, Shi Jiao pleaded for mercy and admitted his mistake, while running away. A domestic dog came running, and Cao Zhuang was still angry. He hacked the dog to death with one knife. After this incident, Jiao suddenly repented and the family lived in harmony.
But mortals are so angry with Cao Zhuang that they have to pay some consequences for the reality, otherwise it will be difficult to calm their anger. When there is a contradiction between people, they often try to take it out on each other for a meaningless angry remark, which is not good for anyone. It's even worse if evil spirits turn into real consequences.
