English Original
A wolf and a jackal often hunted together. Once, they came across a sheepfold with walls that were too high and sturdy for either to climb alone. They devised a plan: the wolf, with its long forelegs and short hindlegs, stood on the shoulders of the jackal, who had short forelegs and long hindlegs. By standing on its hind legs, the jackal lifted the wolf high enough to scale the wall and reach the sheep.
This idiom describes the act of collaborating with others to do evil.
中文翻译
一只狼和一只豺经常一起捕猎。一次，它们遇到一个羊圈，围墙又高又坚固，任何一方都无法独自翻越。它们想出了一个办法：狼的前腿长、后腿短，而豺的前腿短、后腿长。于是，豺用后腿站立，狼则站在豺的肩膀上。这样，狼就被举高，得以翻过围墙，进入羊群所在之处。
