Hello ! Is this Mr . Chang ?   Yes . Who is speaking ?   This is Kelly speaking . I am calling from London . How are you , Mr . Chang ?   Oh , Kelly , I couldn't recognize your voice . Well , I'm fine .   Mr . Chang , I just want to tell you that we are leaving London for Beijing by flight CP 645 on Saturday morning . Could you meet us at the airport , please ?   Excuse me , I couldn't quite hear you . This line is crossed . Can you speak louder , please ?   I will say it again ... Do you hear me now ?   Much better . I will definitely go to the airport to meet you .   Thank you very much . Goodbye .   Goodbye .
