Person1: Hi , I'm Benjamin . Nice to meet you here . You look great .
Person2: Thank you . Nice to meet you too . I'm John . Is this your first time to take a long-distance trip on plane .
Person1: No , this is the second time . But I also feel bad because of the lower pressure and the jet lag .
Person2: Oh , I am sorry to hear that . Take it easy . It will be OK soon . You see , I take this long-hour plane frequently , but the jet lag still makes me uneasy .
Person1: Oh , that's too bad . Do you get a good knowledge of China ?
Person2: Yes , whenever I think about China , I'd see the Tian'an Men Square . China is a very beautiful country . And I've seen many landmarks in China but I like the Great Wall most .
Person1: All of the Chinese are proud of the Great Wall . And it was built before the In dynasty near Shan Haiguan-the First Pass in the World .
Person2: Was it built before the In dynasty ? I thought it was in the Ming dynasty .
Person1: No , before the In dynasty .
Person2: Oh , yeah . Thought I am an American , I know quite a lot about China and I like Chinese tea very well .
Person1: Both the green tea and the black tea are good for our health . And I usually refresh myself with a cup of tea .

Ex Input:
Person1: So , are you enjoying the performance so far ?
Person2: Well , the costumes and the set are marvellous , but the acting is a bit stiff . What do you think ?
Person1: I think you're being a little critical . The actor in the lead role is fantastic . I suppose the chorus could be a bit better , though .
Person2: Do you know anyone in the play ?
Person1: Actually , the woman playing Ophelia is a past classmate of mine .
Person2: Really ? Is that why you wanted to come to the play ?
Person1: That's only part of it . I absolutely adore this director . Every play he works on turns out great .
Person2: So you've seen other plays that he's directed ?
Person1: Quite a few actually . By the way , after the play , there's always a big party for the cast and their friends . My friend has invited us . Do you want to go ?
Person2: Sure , I'd love to meet the cast ! Have you ever been in a play ?
Person1: I've never had a part in a play before , but I used to be a part of the stage crew in high school .
Person2: What did you do ?
Person1: I helped build the sets and find props for the plays . What about you ?
Person2: I once helped out with costumes , but I didn't enjoy it very much .
Person1: Why not ?
Person2: I spent over three weeks sewing sequins on a coat .
Person1: That sounds kind of boring . Oh , look . They're dimming the lights . I think we should get back to our seats for the second half of the play .
