Excuse me . Do you study Chinese at the university here ?   Yes , I do . But my characters are very bad .   It takes a long time to learn Chinese writing .   Are you Chinese ?   Yes , I am . I am from Taiwan . I came here to study political science .   How do you like it ?   I like it so far . But my English still needs work .   I want to study Mandarin and international relations .   Does the Chinese department here teach regular characters or simplified characters ?   They teach regular characters .   I see . I'm from Taiwan , so I know regular characters better than simplified .   You just said your English needs work , yes ?   Yes , that's true . Especially my writing . I think my papers aren't good enough . I make too many grammatical mistakes .   Well , I am very serious about learning Chinese.But for me the hard part now is pronunciation.You have the four tones in Chinese . It is very hard . Maybe , if you have time , maybe we could do a language exchange .   You mean you and I ?   Yes , why not ? I mean , if you come to this cafe often , maybe we could meet here and practice Chinese and English .   That sounds like a good idea . How often would you like to do it ?   Let's see ... My schedule right now is quite busy.But I think I could spend 90 minutes a week in language exchange .   How would we manage it though ? How would we spend the 90 minutes ?
