Chinese Lesson #1: Greetings and thanks

For the benefit of my pals Jocelyn and Lisa, for our upcoming China trip, but feel free to peruse, if you like...

Hello = Ni hao (pronounced "nee how")
Hello (to more than one person) = Ni men hao ("nee men how")
Thanks = Xie xie ("sheh sheh")
You're welcome = Bu xie ("boo sheh")
