How big are Chinese cities? That depends on how you measure them.
Back in 2005, Time magazine proclaimed that Chongqing had become “the largest city not only in China but in the world”, with a population in excess of 30m.
But any Chinese citizen will tell you that Beijing and Shanghai, both with real urban populations below 15m, are larger than their supposed competitor in China’s southwest.
