In the Spring and Autumn Period, there was an upright minister named Shi Hou in the State of Wei, and Shi Hou had a son named Shi Hou, who helped Duke Wei Zhuang's son Zhou Hu kill Duke Huan of Wei and usurp the throne as king. After Zhou Hu came to power, with the help of Shi Hou, he oppressed the people internally and used troops for no reason externally, causing the anger of the people. Shi Bei was very angry with his unworthy son, and he was determined to eliminate harm for the people. One day, he falsely proposed to Zhou And Shi Hou to ask them to go to Chen Guo to find Chen Huangong and ask Chen Huangong to go to Zhou Tianzi to collect a reward for them. Secretly, Shi Wei consulted with Chen Huangong again, and as soon as Zhou Wu and Shi Hou arrived, they detained the two of them.
Zhou Wu and Shi Hou did not know what the plan was, and rushed to Chen Guo, where they were immediately detained by Chen Huangong. Wei Guo sent people to Chen Guo to execute Zhou Wu, and Shi Bei also sent his courtiers to Chen Guo to execute Shi Hou. People have praised Shi Bei's behavior as "great righteousness and annihilation of relatives".
The idiom "great righteousness destroys relatives" thus comes from this. This idiom refers specifically to upholding justice, not shielding and conniving at relatives who commit crimes, and making them punished by law.
