捕风捉影 (Bǔ fēng zhuō yǐng)

Basic Info

• Chinese Idiom: 捕风捉影 (Bǔ fēng zhuō yǐng)
• Pinyin: bǔ fēng zhuō yǐng
• Literal meaning: “To catch the wind and grasp at shadows.”
  (捕 = to catch; 风 = wind; 捉 = to seize / grasp; 影 = shadow)

Figurative Definition

Originally, it described things as elusive and impossible to grasp, like the wind or a shadow. In modern usage, it means to speak or act without any factual basis – to make claims, accusations, or plans based on rumors, imagination, or flimsy evidence. It is a strong criticism of groundless talk and unsubstantiated allegations.

Cultural & Historical Origin

This idiom comes from the Book of Han (《汉书·郊祀志》).

The original passage describes people who claimed to have seen or heard spirits and divine beings:

听其言，洋洋满耳，若将可遇；求之，荡荡如系风捕景，终不可得。

Listening to their words, they fill the ear and seem about to be met with; but when you seek them, they are as vague as tying up the wind or catching a shadow – in the end, they cannot be obtained.

Here, “景” is an ancient form of “影” (shadow). The image is clear: wind cannot be tied down, and a shadow cannot be caught. Later generations shortened the phrase to “捕风捉影” and applied it to any claim or story that has no solid factual foundation.

Key Lesson

Demand evidence before you believe or repeat something. Wind cannot be caught, and shadows cannot be held – just as rumors and speculation cannot stand up to serious scrutiny. A wise person does not spread accusations or build plans on hearsay. In the age of viral misinformation, this idiom is a timely warning: do not mistake noise for truth.

Cultural Note

In modern Chinese, “捕风捉影” is often used to criticize irresponsible media reports, false accusations, and gossip. It is closely related to “道听途说” (dào tīng tú shuō – hearsay) and “无中生有” (wú zhōng shēng yǒu – creating something out of nothing). It can appear in legal contexts, political commentary, and everyday arguments:

“这些指控纯属捕风捉影。”
(“These accusations are completely groundless.”)
