It’s made up of three vignettes about different buildings in Beijing: a museum, an abandoned hospital, and a detention center. The latter two vignettes are especially interesting. In the second, a woman wanders around the ruins of a hospital built in a week to deal with the 2003 SARS outbreak. The third concerns a former prisoner, tracing out a map of the detention center where he was held in 2011.
