Jiang Dianlin (C) from Nanyang city cries as he shows his petitioning paper to Reuters journalists near the State Bureau for Petitions and Visits, which handles applications from petitioners from all over China, in Beijing July 23, 2013. Petitioning the central government - part protest, part entreaty - is seen by many as the only chance of redress in a country where law courts can be manipulated by the very officials responsible for injustices. Only a tiny minority solve their problems through petitions, according to many studies, but some people still fight on, sometimes for years, abandoning families and livelihoods.

A farmer turns soil in front of new buildings and power lines being built on former farming land in the town of Nanyang in Henan Province, March 28, 2010. Gushi, a county some thousand kilometres south of Beijing, is a microcosm of the urbanisation tide reshaping China, driving investment to the country's poorer interior, devouring farmland and creating cities that will absorb more residents than the total population of the United States in coming decades. This metamorphosis of farms to factories is at the heart of how China's economy, a welterweight in global terms in 1980, could be the world's biggest a decade from now. Picture taken March 28, 2010.
