'Ant tribe' growing: Survey

Beijing - Dressed in a crisp suit, Li Zhirui, sitting on the window seat of a Beijing bus, silently gazes at the European-style villas, luxury cars and illuminated shopping malls as they pass him by.

As soon as his stop arrives, he takes off his tie and walks to his rickety second hand motorbike parked nearby.

He doesn't even have a license. But he is far away from the city, safe from the traffic police and his colleagues, who might judge his life outside of the office.
