The moral and rationale of "Covering one's ears and stealing a bell" is as follows:

"Covering one's ears and stealing a bell" means to cover one's own ears to steal a bell, thinking that one can't hear it and no one else will hear it. Moral: One should not be clever or self-righteous. If one tries to deceive others, one is actually deceiving oneself; one should never possess what is not one's own, and one should not be a self-deceiver.

"Covering one's ears and stealing a bell" is from "Lüshi Chunqiu - Self-knowledge": "When the people get a bell and want to take it away, the bell is too big to be taken away. When they destroy it with a vertebrae, the bell makes a sound. Fearing that people would hear it and take it away from him, he quickly covered his ears". Cover: cover.

The same word as "deceiving others, deceiving oneself, making a fool of oneself, covering one's eyes and catching a finch, covering one's nose and stealing a fragrance, stealing a bell and covering one's ears, deceiving oneself and others, plugging one's ears and stealing a bell, and blocking one's eyes" is a synonym for each other, and the same word as "to be open and honest" is an antonym for each other.

The fable of "Stealing the Bell by Stealing the Ear":

During the Spring and Autumn Period, a thief wanted to steal something, and saw a big bell hanging in the yard. The bell was made of the finest bronze and was beautifully shaped and patterned. The thief was so happy that he wanted to carry the bell back to his house. But the bell was so big and heavy that he could not move it. He wanted to break the bell and carry it home separately.

The thief found a big hammer, desperately towards the bell, "bam" a loud noise, he was scared a lot. The thief was in a hurry and covered his ears, and realized that the sound of the bell had become smaller. The thief was happy, "cover your ears will not be able to hear the bell!" He immediately found two balls of cloth, the ears plugged, let go and smashed the bell, people heard the bell swarmed to the thief caught.
