东汉的刘宠任会稽太守时，为官清廉，改革弊政，废除苛捐杂税。后来他被朝廷调任主管工程建筑的官员，临行时，当地百姓主动凑钱送给即将离开的刘宠，刘宠不受。老百姓说：“别的郡太守治理时，官吏在民间搜刮，百姓不得安宁。自从太守您上任以来，狗夜里不叫了，百姓也看不见官吏来索要杂税；如今听说您要离任了，所以我们一起送上一点心意。”刘宠实在盛情难却，就从中拿了一枚铜钱象征性地收下。他因此而被称为“一钱太守”。

When Liu Chong served as Prefecture of Kuaiji in the Eastern Han Dynasty, he was known as being very honest and upright. He reformed the corrupt management and reduced excessive taxes. He was later transferred by the imperial court to serve as an official in charge of engineering and construction. Before he left Kuaiji to take his newly appointed position, the local people took the initiative to donate money to him. However, Liu Chong was reluctant to accept it. Then the local people said, “When other prefectures were in office, they exploited the local people, and we could not lead a peaceful life. Since you took office, we haven’t been asked for miscellaneous taxes by the officials and even the dogs have stopped barking at night. Now we know you’re leaving, we’d like to express our gratitude more or less.” Liu Chong found it really difficult to turn down such kindness, so he took only one copper coin symbolically. Because of this, he was called “One-coin Prefecture”.
