Every year in China millions of migrant workers leave their rural towns to find jobs in the cities. These people are the driving forces behind China’s economic boom: they work very hard and for little money to make the trainers, ornaments, designer handbags and toys which we buy. Through the lives of two young women, Chang vividly portrays a world where you can lose your boyfriend and your friends with the loss of a cell phone; where lying about your age, your education, and your work experience is often a requisite for getting ahead; where a few computer or English lessons can catapult you into a completely different social class. This is a powerful and humane portrait of the forces which are shaping China.
