听风就是雨

听风就是雨

Literally means:

hear the wind and mistake it for the rain

Actually means:

speak or act on hearsay

It literally means whenever one hears the wind, he thinks it is raining, and it figuratively means that one believes what he hears and reacts rashly with out checking whether it is true or not. Derogatory.

听见一点儿风的声音就当下雨了。比喻对听到的事或消息，不加核实便信以为真，并轻率作出反应。具有贬义色彩。
