《汉书·志·五行志下之上》
废忠贞被佞臣所惑就要亡国，昏云，天空先是清澈而突然暴风雨来临，昏云微弱而不明。
废忠惑佞，兹谓亡，蒙，天先清而暴，蒙微而日不明。
When loyalty and virtue are done away with and flattering ministers appear, the state will perish. The sky will be dark. At first the sky will be clear, but suddenly there will be a storm of wind and rain. The obscurity will be dim and unclear.
