Source of couplets:
According to legend, during the Ming Dynasty, the imperial clan in Guilin was always arrogant and constantly fighting dogs for the court's gambling and entertainment! Domestic slaves also rely on themselves as royal domestic slaves, and they are even more arrogant, not only bullying the people, but even ignoring the government! Whenever I am extremely bored, I will draw the fighting dogs out and let them bite passers-by for fun! Both the people and the government dare to be angry and dare not speak!
Later, in the second year of the Apocalypse (1622), Cao Xuequan was the first of the "ten talents in central Fujian" and was appointed as the right senator of Guangxi. This man is upright, upright! Before he took office, he had heard about the actions of Guilin's royalty. Sure enough, he secretly decided to kill these thugs down a peg or two! One day, the slaves of the royal family were bored again, so they repeated their plans to let the fighting dogs bite passers-by at will. A scholar couldn't run any further and threw himself on the ground. Fighting dogs ride on the scholar and bite him at will. He is dying. At this time, a pig killer rushed out of the roadside and began to cut off the dog's head, saving the scholar! The slaves of the royal family saw at a glance that it would be great if the common people killed their master's beloved fighting dog! Because there are many people, the pig killer is tied up and sent to the government with the dead dog, asking the government to sentence him to death and pay for the dog!
Cao Xuequan happened to hear about the case. After reading the scroll in detail, I was not afraid of the imperial clan pressure. I acquitted the butcher and even sentenced the royal family to compensate the scholar for medical expenses! When the royal family saw it, they decided that their faces were in danger, but they could not compete with Cao Xuequan in composition. They had long planned to ask for a retrial, and secretly bribed the scholar to change his confession, saying that he and Dou Gou were lovers and friends. What he played with that day was dog fighting. It was the butcher who killed the fighting dog out of bravery and demanded compensation from the butcher!
At the second trial, the scholar was greedy for money and afraid of the influence of royalty. In order to save his windfall, he betrayed the butcher and changed his confession! Cao Xuequan flew into a rage after hearing the confession of the scholar. He was angry and scolded, "All the witnesses and physical evidence are here. Besides, the butcher saved your life, but you don't want to repay him, so you kill him, get along with the dog and treat the dog as a friend. It's unnatural! God forbid, I won't let you go! " After that, I am going to beat the scholar with the official staff, and the scholar can't stand it. Finally, I confessed how the royal family threatened him with false statements with heavy money! The truth of the case is revealed to the world! Cao Xuequan severely sentenced: the butcher is not guilty; Scholar, be friends with dogs, recognize dogs as friends, bite back, get rid of fame, and be a dog for royalty! And angrily wrote on the case file: "Every time you kill a dog, you are a scholar!" " Eternal sentence!
