This book puts everything in life into perspective. In those ten years of absolute absurdity, the most ridiculous story may actually be someone's reality. What's displayed in this book are both the lowest low and the highest high in mankind: Twisted psychology, horrendous torture methods, unimaginably awful environments led to the deepest sufferings, despair and pain of a billion-population country for a whole decade, but even so, glints of love, loyalty, integrity, honesty, mercy, conscience, and many more precious human qualities still managed to survive and thrive. In Feng's epilogue, he said he was shocked to receive a letter from a youth unable to believe all the stories had really happened until his father explained the situations back in those years to him. We need to preserve the memories of that dark period so that history will not repeat itself. We need to let more understand.
