What is the behavior of covering one's ears and stealing the bell? Classic joke, easy

The Fan family was destroyed, and someone took the opportunity to steal a bell. He wanted to run away with it on his back, but the bell was too big to carry, so he smashed the bell with a hammer. As soon as he smashed it, the bell clanged loudly. He was afraid that someone would hear the sound of the bell and take it away, so he hurriedly covered his ears tightly. He thought that if he covered his ears, others wouldn't be able to hear him. This was ridiculous. The sound of the bell exists objectively. It will ring regardless of whether you cover your ears or not. Anything that exists objectively will not change according to human subjective will. Some people adopt an attitude of not acknowledging the objective existence that is not good for themselves or do not like, thinking that if it is so, it does not exist. This is the same as "covering one's ears and stealing the bell" and is an extreme form of subjective idealism - solipsism. On performance. If you do not face up to the objective reality, do not study it, and adopt a blind and deafening attitude, you will eventually suffer the consequences.
