This undated photo provided by Ablikim Abliz, shows his uncle's family posing with an unknown Han Chinese man, second from the right, in Istanbul, Turkey. Abliz heard the Han Chinese man was part of a government homestay program meant to monitor his relatives, part of a broader crackdown on religious expression in China's far western region of Xinjiang. More than a million Chinese civil servants have been assigned to move into the homes of Uighurs and other ethnic minorities, spending weeks as uninvited guests. While government notices about the "Pair Up and Become Family" program portray it as an affectionate cultural exchange, exiled Uighurs living in Turkey said their loved ones saw the campaign as a chilling intrusion, aimed at coercing Uighurs into living secular lives like the Han majority.
