Commercial complex is now the ultimate destination for a modern consumer. With functions not only of a shopping mall but also a city, it blurs the distinction between public space and commercial space. Because of the integration of city functions, commercial complex seems less "commercial".

We analysed the segmentation the complex appeals to, as well as their lifestyles, trying to find out an universal logic for the trend.
