After watching the related introduction, I found that this is a "textbook-style" movie, full of a lot of metaphors, symbols and vague innuendo to society.
Regrettably, I am so ignorant of talent that I don't really see that the chasing game between a rich old man and a beautiful girl can reflect the irreconcilable antagonism of the two classes.
Perhaps it is simpler to think of it as a film about desire and love that reveals complex human nature.
This is a question of "interpretation".
Finally, it is worth mentioning that the heroine in the movie is amazing.
