After three weeks in China already, Charlee and I just found out from one of our new friends, Jue, how to ask where the toilet is. Every other time that we had been out together we have been able to figure out where the bathrooms are from signs or people traffic - until one of our afternoons of hanging out at that coffee shop across the street from the Hanting.
Apparently, you don't have to say the Chinese word for bathroom or toilet (which would by extremely difficult for us to remember and pronounce correctly). Jue told us that WC means bathroom - which should have occurred to me after seeing signs for WC. Germans, the Swiss, and Austrians also use the term WC for bathroom - something that I became accustomed to during my trip there about five years ago. I don't know why I hadn't thought of that sooner. Now we know.
