Around 200 million workers in China are on the ‘tramp’, erecting the country’s shining metropolises as labourers and running the factories as shift workers. China’s exceptional growth would be inconceivable without this vast army of workers who form the backbone of the Chinese economic boom and are widely regarded as the largest migratory movement in the history of time. And yet theirs is a position on the fringes of society, often living and working in degrading conditions and segregated both socially and legally.
