Shanghai's middle classes are the hardest working residents of China's seven big cities.

They sleep 7.2 hours and work for 9.6 hours everyday, meaning they sleep the least and work the most of the 1,000 middle-class people polled across seven cities.

About 40 per cent of Shanghai respondents said they were under great pressure.
