Plugging One’s Ears While Stealing a Bell(掩耳盗铃)

Plugging One’s Ears While Stealing a Bell
Once upon a time, there was a very foolish thief and he wanted to steal his neighbor’s doorbell. However, he knew clearly that the bell would ring and catch the other people’s attention as long as he touched the bell. So he thought hard and suddenly hit on a clever “idea”. He plugged his ears with something, thinking that everything would go well when he stole the bell. Unfortunately to his disappointment, the bell still rang loudly and he was caught on the spot as a thief.
Chinese people often use this idiom to describe the man who deceives oneself as well as others.

掩耳盗铃
从前，有一个人想偷邻居门上的铃，但是他知道一碰到铃，铃就会响起来，被人发现。他想啊想，终于他想出一个“妙计”，他把自己的耳朵用东西塞起来，就听不见铃声了。但是当他去偷铃时，铃声仍旧响起来，他就被别人当场抓住了。
中国人常用这个成语比喻自己欺骗自己，也就是自欺欺人的意思。
