空穴来风 is a Chinese idiom (chengyu) meaning “Rumors or news, though perhaps exaggerated, are usually not entirely without foundation or cause; there's often some truth or origin behind them”. Literally, “Wind comes from an empty cave”.
During the Warring States period, Song Yu accompanied King Qingxiang of Chu to Lanta Terrace for leisure. Feeling a cool breeze, the King sighed, expressing that he shared this wind with his common people.
Song Yu seized the opportunity to advise the King, saying, 'A curved branch attracts a nest, and wind comes from an empty hole (枳句来巢,空穴来风).' He elaborated that different environments produce different kinds of wind. The wind that passes through your bright mountains and beautiful waters is fragrant, while the wind that blows through the narrow, murky alleys where the common people reside is foul-smelling.
The idiom '空穴来风' is derived from this anecdote, emphasizing that rumors or events, like wind from a cave, rarely arise without some underlying cause or origin, however slight.
