My wife and I spent a week in Guangzhou on our final week of our honeymoon. It's a massive city, equal to if not greater than Hong Kong in population and size. We didn't go to this mall, but we went to a few newly built temples that are similar in scale. Amazing architecture; almost no people. There is a lot of overbuilding going on there, and not a lot of people with disposable incomes. Here's a picture from a newly built temple park near the city.
