I believe you mean T2? T1 is domestic reserved for China Southern. I had the chance to have a quick look at the exterior of the building while passing by the airport. It does look nice indeed! However, expats (like me) who don't know Chinese will have problems finding T3 as you must exit early and the only sign informing you the way to T3 is in Chinese. There is a small, barely noticeable sign but by the time you passed it it would be too late. Oh yeah, I forgot to say, I'm taking about the Airport Expressway.
