Zhou Chengliang is about 27 years old (he doesn’t know for sure), goes by the name Huang Jie, and is an entrepreneur based in the western Chinese city of Lanzhou. He suffers from memories of a lost past: he was one of countless young Chinese children kidnapped and sold to strangers to be raised as their own. Zhou’s story is a human tragedy, but it’s also emblematic of a country in the throes of rapid change, torn between tradition and modernity, challenge and opportunity, morality and corruption.
