An interesting and fairly horrible account of life in China during the cultural revolution. Kang was constantly made to write self-critical and confessional essays, and witnessed ongoing public denouncings and lynchings of friends, neighbours, and family alike. Due to the crazy political climate, even his own family had to denounce him as a thought criminal. Basically the whole society devolved into a paranoid and violent shit show.
Although Kang's main "crime" was keeping personal diaries, for 5 years, he gets transferred from one reeducation/work camp to another, ending up in a village to live and work as a peasant. Even peasants couldn't simply live off the land independently - they also had party cadres monitoring daily progress and assigning "work points".
I think this was a valuable memoir to share, but I enjoyed The Bitter Sea by Charles Li better.
