Why do so many people sharpen their heads and want to emigrate

There are many ideas about "I want to go out for a walk because the world is big".

Everyone has the curiosity and childlike innocence to explore the world.

People who live in the noisy environment of the city for a long time want to stay in the quiet environment in the mountains. People who have lived in the quiet environment of the mountains yearn for the prosperous world of the city. From familiar environment to unfamiliar environment, they are immigrants.

This is a normal psychological need of people. People will emigrate once or n times in their life, but the distance each person moves out is different!
