What are the interesting details of the movie The World?

"The World" is about young people finally coming out of a small town, but their plight has not changed, and they are even lost in the strangeness of the city and even gradually swallowed up. Jia pays more attention to the theme than to the perspective of personal destiny. What you see repeatedly in his works is the survival dilemma of migrant workers or small town residents. His protagonist is constantly imagining life outside his class. If Jia can jump out and see the plight of young people in the small town where he originally belonged because of his own experience, then he can't jump out and see that "those people on the plane" actually have their plight. Instead of showing a broader vision and broad mind, limiting the world to his small town step by step, showing the poor fate of his despised brothers in the county and blaming their fate on their class.
