Chinese Lesson #2: Me, Myself and I; the Interrogative

Today's vocabulary:
Me, myself, I = wou (pronounced "wuo")
We, us, ourselves = wou men ("wuo men")
The interrogative suffix = ma ("ma"); for example:
Ni hao = "hello"
Ni hao ma? = "How are you?"
Ni men hao ma? = "How are y'all doing?"
Wou hao = "I'm fine"
Wou men hao = "We're fine"
