Wu Xiaoya was driven out of his village because his mouth was too vicious, and he ran to the county town to make a living. The county magistrate took pity on him and recruited him as a constable. On his first day in office, he said, "There won't be any cases today," and as a result, three murder cases arrived. He said, "The murderer definitely hasn't run far," and as a result, the murderer had already fled the province. He said, "This case can be solved in three days," and as a result, it took three months to solve. The magistrate wanted to dismiss him, and he said, "If you dismiss me, you're going to have bad luck," and as a result, the magistrate lost his official seal that very day. The magistrate didn't dare to dismiss him anymore, keeping him as a mascot, but never letting him open his mouth to speak.
