'Better city, better life', is the theme of Shanghai's Expo 2010, which closes at the end of the month. The city is home to 20m people and it seems, as locals rush to see the international pavilions before they close, about 19m are there every day at the moment. More realistically, over 1m passed through the turnstiles last Saturday (16 October) and the wait for popular pavilions such as China's own could be as long as five hours.
