“狼狈为奸”这个成语大家很熟悉。古人认为狼和狈是两种奇异的野兽。狼的前腿长,后腿短,狈的前腿短,后腿长。狈必须趴在狼的身上,才能行动;狼必须依靠狈,才能直立起来。所以用“狼狈为奸”来形容坏人彼此勾结作恶是很形象的。 “Complicated” as the idiom we are familiar. The ancients think wolf and embarrassed are two kinds of strange beasts. Long front legs wolf, hind legs short, awkward front legs short, long legs. Must be lying on the wolf's body in order to act; wolf must rely on embarrassment, to stand upright. Therefore, it is very imagery to describe the bad guys as colluding with each other and doing evil with “working in collusion.”
