Sayragul Sauytbay, an ethnic Kazakh teacher who later fled China, described how she was forced to teach at a re-education camp, saying the camp was "cramped and unhygienic" with her detainee students given only basic sustenance. Sauytbay added that authorities forced the detainees to learn Chinese, sit through indoctrination classes, and make public confessions. Furthermore, she mentioned that torture and rape were common and that authorities forced detainees to take a particular medicine that left some individuals sterile or cognitively impaired.[145][146]
