A man surnamed Xu, 50, walks past a house carrying the Chinese character "Chai", meaning "demolition", in Guangfuli neighbourhood, in Shanghai, China, April 8, 2016. Xu's whole family used to live under the same roof together in Guangfuli. In a corner of Shanghai, surrounded by a cement wall, lies one of the world's most valuable fields of debris and garbage. On paper, the Guangfuli neighbourhood is a real estate investor's dream: a plot in the middle of one of the world's most expensive and fast-rising property markets. But the reality is more like a developer's nightmare, thanks to hundreds of people living there who have refused to budge from their ramshackle homes for nearly 16 years as the local authority sought to clear the land for new construction.
