在汉语里,有不少以鼠为喻的词语。鼠性卑猥,偷窃为生,故日“鼠窃狗盗”。鼠胆虚怯,一有动静便钻洞适窜,故日“胆小如鼠”、“抱头鼠窜”。鼠害甚烈,人之所憎,故又有“老鼠过街,人人喊打”之说。推而论之,可鄙可憎之徒,也就被称为“鼠类”、“鼠辈” In Chinese, there are many words that are rat-like. Mouse sexual humble, stealing a living, so the day “rat stealing dog steal.” Rats timid fear, there is movement will drill hole suitable channeling, so the day “timid as a rat,” “hold head rat channeling.” Very rodent, people hate, so there are “mice across the street, all shouting” that. In short, despicable detestable, also known as “mice”, “rats”
