The neurobiologist Rao Yi had the ill fortune six years ago to buy a “rotten tail building”. In Chinese the phrase refers to a development that is left unfinished when the funds are embezzled. It was part of a sharp learning curve as Rao returned from the US, where he had worked for more than two decades, in a bid to further Chinese science.

On this bright morning in Beijing, as children play in padded coats under a tree nearby, it is hard to see any signs of rot. The quaint paved roads and sleepy porches in Rao’s gated compound, a 25-minute walk from Peking University, bear some resemblance to suburban America, although the red lanterns that hang from some of the doors are distinctly Chinese. Today, the site is calm and peaceful but Rao assures me that the developers behind the smart new complex are now serving time in prison for misappropriation of funds.

Here in China it is an all too common story. Rao paid for his four-bedroom house in 2007 but the money disappeared and the building works stalled. He had to wait a further four years to move in. “A lot of people went on protest,” says Rao, gesturing vaguely to his neighbours. “I did not because if I got involved, they thought it would be too much publicity. They said you can if you want but if you don’t it would be?.?.?.?” he pauses, “?.?.?.? nice.” Exactly who said this remains unclear. When probed, Rao waves his hands dismissively. “People called,” is all he will say.
