What is the man going to do tomorrow afternoon?

M: Liuhua, shall I invite you to drink tea at the Garden Teahouse?
W: Ok, when?
M: How about tomorrow afternoon?
W: No problem. I remember that you like coffee most. Why do you want to drink tea suddenly?
M: I do like coffee, but I have recently taken interest in China’s tea culture and want to visit a teahouse.
W: Let me quiz you first. What kind of tea do the Chinese like best?
M: That’s too easy, black tea, of course.
