Why can't the increasing purchasing power for vehicles lead to better civilized behavior on the roads in Beijing?
How necessary is it to buy a car when traffic jams are happening every day?
What are the complex feelings and compressive stresses of ordinary people under an atmosphere where people are labeled by whether they own a car or not, and by the brands of their cars?
THE BEIJING JAM's approach is to portray these issues through the lens of traffic jams.
(Note: "THE BEIJING JAM" seems to be the title of a documentary or a project, so I capitalized it for emphasis.)
