拿镜子照一照

拿镜子照一照

Literally means:

look at oneself in the mirror

Actually means:

evaluate oneself rationally

It literally means looking at one's own image in the mirror. It figuratively means one should evaluate oneself reasonably, especially finding out his deficiencies in dealing with other people or handling problems. It is often used to criticize someone who only finds fault in others but never admits his own shortcomings, or who ignores his own deficiencies or weakness but dreams of achieving something beyond him. Derogatory.

照镜子，看看自己的长相。比喻必须正确评价自己，特别是应该反思自己在做人或处理事方面的不足之处。常用来批评某人只知道批评和指责别人而不检讨自己的缺点或不足，或者因看不到自己的缺陷或弱点，妄想做自己做不到的事情。具有贬义色彩。
