《资治通鉴·唐纪·唐纪五十九》
穆宗怜悯韩绍宗，于是，把韩弘家里的财产登记本全部调来，亲自审阅，发现朝廷内外凡当权的官员，大多接受过韩弘的贿赂。登记本上只有一处用红笔小字记裁着： 某年某月某日，送户部牛侍郎钱一千万，拒而不收。 
上怜之，尽取弘财簿自阅视，凡中外主权，多纳弘货，独硃句细字曰： 某年月日，送户部牛侍郎钱千万，不纳。 
Muzong pitied Han Shaozong, and so ordered for all the property records of Han Hong's family to be brought up, and he personally reviewed them. He discovered that the majority of the officials, both within and outside the court, had accepted bribes from Han Hong. Only one record was annotated with small red characters: On a certain day in a certain month of a certain year, a sum of one million qian was given to Niu, the Minister of Revenue, but he declined to accept it.
