Those who have seen the film Chongqing Forest, please explain what this name means.

Chongqing Forest was not filmed in Chongqing, nor was it about a forest. Chongqing Forest is a hotel, which is the residence of Wong Kar-wai when he first immigrated to Hong Kong-Chongqing Hotel. Another movie fan thinks that the film shot some scenes in a place called chungking mansions, in which the so-called "forest" actually means the same thing as the "steel forest" we often say. Chen Jia, a film producer, believes that the audience should not pay too much attention to all the symbolic things in the film when watching it. The new generation movies under Wong Kar-wai's queer theory are a faint feeling in the creator's heart and have an indescribable charm. Let's watch the movie excitedly and savor the impulse brought by the word "Chongqing forest"! The first story: the lovelorn and boring policeman 223 fell in love with a female killer wearing a golden wig. The mysterious blonde used several Indians to transport drugs, and the Indians cheated her. After killing the Indian, she ran away and met a lovelorn plainclothes detective in a bar. The blonde was tired and fell asleep in chungking mansions, and 223 watched her leave in the early morning. Policeman 223 runs away every time he is lovelorn. When he was about to leave in the rain, the pager received a birthday wish from the blonde. The second story: The girl who works in a fast food restaurant has a crush on the policeman who comes to buy snacks every night. Police 663 buys chef's salad for his girlfriend in the "midnight express" fast food restaurant every day, and later buys her fried fish steak for a change. His girlfriend suggested that she change her taste. The girl in the fast food restaurant opened the letter left by the policeman's girlfriend in the fast food restaurant and got the key to the policeman's house. Later, she often secretly went to his house to clean and decorate, just like sleepwalking. One day, I was caught by a policeman. That night, 663 asked her to meet in a California bar. The girl went to real California and left him a letter. 663 never knew the place agreed in the letter. A year later, the girl came back to her cousin's fast food restaurant. 663 is already the owner of this shop. The girl wore a stewardess uniform and wrote a new "boarding pass" for 663.
