A good book, and even though it's memoir, an interesting book for the fiction writer, especially the fantasy or science fiction writer, for two reasons.
The first is it's about stories as well as about the Cultural Revolution. Why we tell stories and what they mean.
And the second is that even though it's a memoir, large chunks of it read like magic realism. Cool stuff. Explanations of this or that, or the stories the narrator is told, and -- hints.
