Xianhui Yang’s “Woman From Shanghai: Tales of Survival From a Chinese Labor Camp,” a newly translated collection of firsthand accounts that the publisher calls “fact-based fiction,” is about what might be called the Gulag Archipelago of China. Reading it, one begins to appreciate why travelers to North Korea are so reluctant to reflect on human suffering: the reality of North Korea today is too painfully close to a situation endured by the Chinese well within living memory. As the circumstances of the publication of “Woman From Shanghai” help us understand, these are memories that the Chinese state still works hard to suppress.
