If you see a person who is constantly simulating the bowling game in iphone, swinging his mobile phone to play games; or a woman who is giving a striptease performance in front of you while she is originally dressed from head to toe, don't be surprised. These have become a special scene in the subway. The high frequency of weird shapes appearing in the metro has almost become a kind of common fashion show.
