Chinese development has depended on a vast influx of 250 million migrant workers into the cities - some have prospered but most are poorly paid and housed, with few rights. Mass protests mean the government can no longer take them for granted.
THE TRAINEE CHEF'S STORY Li Xu Bin is a migrant worker like millions of others, on low pay and with little job security, living with his wife in a single room in Beijing's suburbs. They have left their child behind, the cause of much heartache.
THE FRUIT VENDORS Like Li Xu Bin, Mr and Mrs Zhang have moved to the city to earn money to pay for their children's education. The rules say their children must stay behind. Meanwhile they have to work all hours to make ends meet. Says Mrs Zhang: "We never have a single day off."
