Abuse or torture
"... At some point, they asked about my religion, and I told them I prayed five times a day. I told them I was a practicing Muslim. They took me to Ghulja. There the police interrogated me again. The same questions, but this time they beat me. You’ve been to a Muslim state, they said. Why didn’t you take their citizenship? Why are you here? After beating me, they brought me a piece of paper to sign and put my thumbprint on it. Then they took me to the camp."
