This clip is about numbers, and the varying ways to make sense of them in China. At one extreme the power of numbers is of obvious and unignorable importance. The opening scene of the clip, on a winter day in Shanghai, give a glimpse of the sea-of-people effect of many Chinese cities. On the other hand, neither Shanghai nor Beijing nor any other city in the mainland seems as densely packed as either Tokyo or Hong Kong. The difference with mainland China is that there are so many multi-million person cities across so huge a landmass, plus plenty of well-populated rural areas too.
At the same time, just about any number concerning China is an approximation, from economic growth rates to literacy or environmental readings, or anything else. This clip mainly talks about the implications of that rough-and-ready statistical approach for businesses, but it has international and political implications too.
