1. There is no such thing as personal space in China. If you don't like people surrounding you all the time, you may very well have a panic attack within 5 minutes of being here.
2. Smoking is a national pastime here. If smoking doesn't kill you, then the 2nd hand smoke might.
3. The high-speed train is awesome. Students did not get to ride this..only me, as I had to go to the airport and back to pick up a 'found' iPad that a student had left on the plane.
