history
From the Jin Shu biography of 谢玄. After the rout at Feishui (383 CE), the fleeing 前秦 soldiers heard 'the wind and the cries of cranes' and mistook every sound for pursuing troops. Often paired with its sister idiom 草木皆兵.
memory
风声 (wind sound) + 鹤唳 (crane calls) — two harmless natural sounds that terrify an already-spooked mind. A vivid snapshot of paranoia.
