《太平广记·卷四百六十六·水族三》
韩愈说： 我听说至诚能感动神仙，从前鲁恭主管中牟的时候，雉鸡驯服而且蝗虫也躲避起来，黄霸治九江的时候，老虎都悄悄地离开了九江，这是因为，执政者有良好的政绩，禽兽也能被感化。 
愈曰： 吾闻至诚感神，昔鲁恭宰中牟，雉驯而蝗避；黄霸治九江，虎皆遁去。是知政之所感，故能化禽兽矣。 
Han Yu said: I heard that utmost sincerity can move immortals and gods; in the past when Lu Gong was in charge of Zhongmou, the pheasants became tame and the locusts hid themselves; when Huang Bo governed Jiujiang, the tigers quietly left Jiujiang. This was because those in power had good political achievements, and even the birds and beasts could be transformed.
