Specifically, much of the film deals with Changhua and Sugin Zhang, who left their kids in the care of their mother (the kids’ grandmother) for city jobs. The daughter Qin has grown into a rebellious teen, leading to a family blowup at the end of the film, caught by the documentary filmmaker.
The film covers the mass crowds and overselling of tickets, and delay of trains in a February blizzard.
The life in the countryside appears to have some of the trappings of the old Maoist past, from the cultural revolution.
The conditions in the Chinese factories are crowded and unpleasant, and the workers live in crowded dorms. Still, there is some shopping and entertainment, but their hours are much longer than those in the US.
The values of US consumerism are questioned. Only American men have 40-inch waistlines, it is said.
The film comes from Canadian production companies (including Eye Steel Film and cable TV) and has theatrical distribution by Zeitgeist.
