"I was very much afraid to sign... It said there that if I did not fulfill my task, or if I did not obey the rules, I would get the death penalty."

"The document stated that it was forbidden to speak with the prisoners, forbidden to laugh, forbidden to cry and forbidden to answer questions from anyone. I signed because I had no choice, and then I received a uniform and was taken to a tiny bedroom with a concrete bed and a thin plastic mattress. There were five cameras on the ceiling – one in each corner and another one in the middle. [For less privileged inmates:] There were almost 20 people in a room of 16 square meters [172 sq. ft.]... There were cameras in their rooms, too, and also in the corridor. Each room had a plastic bucket for a toilet. Every prisoner was given two minutes a day to use the toilet, and the bucket was emptied only once a day. If it filled up, you had to wait until the next day. The prisoners wore uniforms and their heads were shaved. Their hands and feet were shackled all day, except when they had to write. Even in sleep they were shackled, and they were required to sleep on their right side – anyone who turned over was punished."

Sayragul Sauytbay offers firsthand testimony from a Xinjiang 'reeducation' camp" (Haaretz). There are much worse things in that article than what I've excerpted.
