I used to live near Huagong (South China University of Technology) for a few years. Later, I settled in Suzhou and didn't go back [to Wuhan] for about three or four years. The first time I returned and got off at Guanggu (Optics Valley), I was absolutely stunned. How could there be so many people? The crowds crossing the street were incredibly dense; it felt like hundreds crossing at once. I just went back again this May Day and visited a Poly residential complex. The buildings are all over 40 stories high, with 16 units per floor. So many buildings, all densely packed, and the ground floors were just as crammed with restaurants.
