《智囊(选录)·察智部·包拯》
宋朝人包孝肃治理天长县时，有位县民向官府报案，声称所养的牛只遭人割断舌头，包公要他回去把牛宰杀后，再运到市集出售。不久，有人来县府检举某人盗牛贩卖，包公却对他说： 你为什么先前割断那人所养牛只的舌头，现在又想诬告他是盗牛者呢？ 
包拯包孝肃知天长县，有诉盗割牛舌者，公使归屠其牛鬻之，既有告此人盗杀牛者，公曰： 何为割其家牛舌，而又告之？ 盗者惊伏。
When Bao Xiaosu of the Song Dynasty governed Tianchang County, a county resident reported to the government that his ox had his tongue cut off. Bao Gong asked him to go back and slaughter the ox, and then transport it to the market for sale. Soon, someone came to the county government to accuse a certain person of stealing and selling the ox, but Bao Gong said to him: “Why did you cut off the tongue of the ox that man raised before, and now you want to falsely accuse him of being a cow thief?
