From 1979 to 2015, there was a regime very much like that in “The Handmaid’s Tale,” but instead of prohibiting abortions, it mandated them—along with involuntary sterilization (of mothers, not fathers). When China’s notorious one-child policy was in full effect, the communist regime relentlessly intruded into bedrooms and families’ lives. The draconian mandate has been relaxed to a “two-child policy,” but the guilt and emotional pain persist for the parents who were forced to comply. Filmmakers Nanfu Wang and Jialing Zhang expose the resulting trauma, both on a national level and within Wang’s own family throughout “One Child Nation,” which was released in the United States on Jan. 26, 2019.
