📖 Meaning
An expression describing a state of extreme fear and paranoia where one mistakes the rustling of wind and grass for approaching soldiers and weapons. It is equivalent to the idiom 草木皆兵 (seeing enemies in every tree and bush). The phrase conveys how panic can cause people to perceive threats in ordinary, harmless things.
📜 Origin Story
This idiom originates from the classical novel 'Water Margin' (水浒传), Chapter 95, one of China's Four Great Classical Novels attributed to Shi Nai'an. In the passage, the context describes troops gripped by fear, where every shadow and sound—ghostly carriages, phantom snakes, wind-blown soldiers, and grass-covered armor—becomes something that shakes their resolve. The expression draws on the same psychological phenomenon as the famous Battle of Fei River, where the frightened soldiers of Fu Jian's army mistook trees and bushes for enemy troops. It vividly captures how terror warps perception, turning innocuous surroundings into imagined threats.
💡 Example Usage
敌军已是风兵草甲，稍有动静便自相惊扰。
The enemy troops were so paranoid that they mistook every sound for an attack and panicked among themselves.
