After the establishment of the Ming Dynasty, Zhu Yuanzhang believed deeply in blood relationships, so he divided his descendants into kings across the country. After Emperor Jianwen came to power, he ordered the reduction of vassals in order to eliminate the threat posed by the vassal kings to the central government. But Emperor Jianwen not only failed to cut it, but also got himself involved. After King Zhu Di of Yan usurped the throne, in order to prevent future generations from imitating him, he cut off the vassal king again and again. The princes of the Ming Dynasty, big and small, were princes at best, or local landowners at worst. However, this group of landowners were supported by the imperial court and lived a very comfortable life. However, they often acted without the king's laws in the local area. Because these princes were related to the emperor, most local officials did not dare to offend them and mostly turned a blind eye. In the second year of Tianqi (1622), in a busy market in Guilin, a vicious dog chased and bit a weak scholar. Seeing that a living man was about to be killed by a vicious dog, a butcher selling meat not far away came up with a knife and killed the vicious dog with one blow, saving the scholar's life. The butcher did a good deed but also got into trouble because he killed the dog without looking at the owner. This vicious dog was raised by a local prince in Guilin. In the eyes of this clan king, his pet dog was much more valuable than these ordinary people. So after the dog died, the slaves could not go back to pay for their duties, so they captured the butcher and the scholar and sent them to the government. The feudal king did not have administrative and judicial power in the local area, so the domestic slaves did not dare to mess around. The person who took over the case was Cao Xuequan, who was the right councilor of Guangxi at the time and was a new official who had just taken office. In the courtroom, the butcher and the scholar explained the situation in detail. Finally, Cao Xuequan concluded that the butcher acted bravely and was acquitted! For the servants in the palace, such a result would not allow them to go back to report, but they had no choice but to go home and report to Cao Xuequan. The prince, who was used to being arrogant in Guilin, realized that this was definitely not as simple as a dog. Cao Xuequan has taken office as a new official. If he doesn't control him, his good days will be over. Cao Xuequan also understood that if he didn't have the courage to kill the prince, he would not be able to survive in the future. Therefore, a fight between the court officials and the clan princes triggered by a dog broke out. The servants of the palace found the scholar and asked him to retract his confession and frame the butcher. The scholar's original intention was not to obey, but he still couldn't resist the temptation of money. So this case, which was ready to be closed, was presented to the scholar again. This time the scholar overturned all his previous confessions, saying that those words were threatened by the butcher, and that he was just playing with the prince's pet dog that day, and the butcher killed the dog on purpose. There is no doubt that the prince just wants to kill the butcher. Cao Xuequan also understood that if he convicted the butcher, it would mean he lost. What's more, the butcher is a brave man. If he is sentenced, who will believe that he can enforce the law impartially? The attitudes of the scholars and domestic slaves made it clear to Cao Xuequan at a glance: they were colluding to frame the butcher. Cao Xuequan was immediately furious and ordered his men to beat the scholar 30 times, killing half of his life at that time. Then he sternly scolded the slaves to leave quickly, otherwise they would end up like the scholars! When they went back in disgrace to explain the situation, the prince realized that this Cao Xuequan could not be offended! ?That day, Cao Xuequan announced that the case was closed. Still angry, he cursed loudly in the courtroom: ""Every time someone slaughters a dog with justice, most of them will be a scholar who betrays his heart! "In the end, he also wrote this sentence into the case file, which also allowed this sentence to be passed down. After that, Cao Xuequan became the King of Hell of the clan in Guangxi. Because Guangxi is located in a remote area, some people relied on the vassal The king's forces secretly minted currency, which was equivalent to today's counterfeiting. In the Ming Dynasty, this crime was punishable by death, so those who were investigated by Cao Xuequan would definitely not be spared alive. During Cao Xuequan's tenure in Guangxi, the local government All the vassal kings were in awe of him and kept their tails between their legs, fearing that Cao Yan would find out his old ways, otherwise the consequences would be disastrous. Having said that, the 14 words Cao Xuequan scolded the scholar may be a bit overgeneralized. In many stories from ancient times to the present, it has always worked, at least in the case he tried.
