六月飞霜

六月飞霜

Literally means:

summer frost

Actually means:

unjust case

Originally it refers to an unjust case or injustice. It is said that in the ancient times a king was taken in by an evil person and arrested an official loyal to him. The arrested official looked at the sky, crying out words of grievance in rs. It was summer, but the Heavenly Emperor commanded that frost fall onto the ground in order to show his sympathy toward him.

As we know, it is impossible that frost appears in the hot month of June in the lunar calendar, so the phrase is now a metaphor indicating things that are impossible to happen.

原先比喻冤案、冤情。据说，古代有个国王听信坏人的话把一个忠臣抓起来。这个忠臣头望青天，哭着喊冤。当时正是夏天，老天爷下起了霜，对他表示同情。 因为六月天热不可能下霜，所以现在用来比喻根本不可能出现的事情。
