Why was the film Chinatown named that way?

The film "Chinatown" was named after the Los Angeles neighborhood, which symbolizes a place of mystery, corruption, and moral ambiguity. The setting reflects the complex themes of the film, revolving around deception and the darker side of human nature. Additionally, the title serves as a metaphor for the protagonist's journey, illustrating how he becomes ensnared in a web of intrigue and betrayal, much like the city itself. Director Roman Polanski intended for the title to evoke an atmosphere of entrapment and the inescapable consequences of the characters' actions.
