Chinese migrant workers
A "mangliu" or migrant worker without a contract, descending daily on Guangzhou, sits with his few belongings 14 March 1991, outside the railway station waiting for work, next to an endless queue of people lining up for train tickets, in this southern provincial capital. In China, million of peasants are looking for a better life in the city, hundreds of thousands of them waiting at railway stations for a job.
