Nanfu Wang on going back to China and avoiding surveillance to make One Child Nation
\u201cOne Child Nation,\u201d a documentary about the devastating effects of China\u2019s one-child policy, has been nominated for many awards. But director Nanfu Wang says any film buff who has to rely on Chinese media to follow these competitions wouldn\u2019t even know her film exists -- it's totally banned in China. Wang tells us about making \u201cOne Child Nation,\u201d which started as a personal story and grew into something broader.\xa0
