风声鹤唳

fēngshēng-hèlì

[the whining of the wind and the cry of cranes; a fleeing army's suspicion of danger at the slightest sound; be so nervous and fearful that a slight movement in the wind is enough to make one jittery] 鹤唳: 鹤叫。 《晋书·谢玄传》记载, 东晋时, 秦主苻坚率众攻晋, 列阵淝水, 谢玄等率精兵击破秦军, 秦军在败逃途中极度惊慌疑惧或自相惊扰。 "闻风声鹤唳, 皆以为王师已至"。 形容非常慌张, 到了自惊自扰的程度

风声鹤唳, 草木皆兵
