A heavy pall of pollution hangs over Tiananmen Square and from a distance the giant portrait of Mao Zedong above the entrance to the Forbidden City looks a little smudged. It is 8am and the temperature in central Beijing is already approaching 30C. But the heat and smog are no deterrent to the thousands of people waiting in hour-long queues to pay respects to the preserved body of the “great helmsman”. Since his death 40 years ago, Chairman Mao’s corpse — or, more likely, a wax replica — has been on display in a purpose-built mausoleum in the geographic and figurative heart of the Chinese capital. Well over 200 million people have visited.[Source]
