Let ’ s go to WAngFuJing by bus .   Better take the subway . It ’ s faster and more convenient .   Okay . It will be a new experience for me .   We have a rather comprehensive subway system here . we can get almost anywhere rather quickly on the subway . Especially at this time of a day when the traffic is heavy .   where do we pay the fare ?   Just give the man standing there three yuan and he'll give you a token . Then you slip it into slot at the turnstile and push the turnstile to get in .
