What are the metaphors in the movie Parasite?

Parasites is certainly not the best in the personal dimension directed by Bong Joon ho. My favorite Bong Joon ho movies are Mother and Memories of Murder. There are profound extreme figures in Mother, and there is a completely real social environment in memories of murder. These two points, "parasites" failed to do. In my opinion, whether it can successfully gain such a reputation depends on the balance between extreme typology and social expression. The recognition of Cannes is more like the recognition of the whole Korean film.

Of course, there are many topics that can be discussed in a movie, but if you know that it is a story about "social class" before watching Parasite, it will help you to concentrate more. Because in the process of watching movies, it is easy to be attracted by the black humor and surprising turning point in the first half of the story, but remember that it is always about "class".

The residence of the rich is not only uphill, but also a flight of stairs to see a piece of green grass and come to the first floor of the house. The rooms of Mr. and Mrs. Park and their children are on the second floor. If you want to contact this family, you must continue to climb. The poor Kim family lives in a crowded and narrow semi-basement. As soon as the window is opened, the disinfectant in the street will be sprayed into the house. Alcoholics urinate outside the window and get flooded when it rains heavily. This dark, bad sour and musty smell just floated out through the screen.

This "upper and lower classes" design is also reminiscent of "We Us" in March this year, which also uses land and land to convey the opposition between the rich and the poor.

In addition to being naive, Park's family is a little naive because they can't stand the "poor taste and subway taste". On the contrary, the Kim family is the one who is good at calculating tricks, but the bottom line is to make a living.

Director Feng Junhao described Parasite as a comedy without clowns and a tragedy without bad guys. In modern society, it is impossible to judge what is good and what is bad. What other metaphors can you see in reality?
