Arriving in the city center the first thing I noticed was the heavy military present. Soldiers were stationed on top of the buildings with cameras and telescopes. There was a soldier stationed at the corner of our hotel's street and we saw many more during our 4 days. It is rare to see a gun in China. Even at NUDT there were few guns visible. China always made me feel a little paranoid but this cranked up my paranoia a couple of notches. American Tourists were scarce- mostly European or Asian.
