TAZHONG, CHINA - JUNE 15: Oil workers wait outside their living quarter to be taken to work on June 15, 2007 in Xinjiang Province in Tazhong, China. They work for China National Petroleum Corporation and the little town is full of brothels that serve the many oil workers there. The workers come from all over China and spend most of their free time singing karaoke, drinking and meeting girls..(Photo by Per-Anders Pettersson)...
