When I was walking with the crowd, it seemed that certain strength was pushing me forward, making me take everything passing by for granted after some time. When I turned around to walk reversely to the crowd, it became difficult, but I could see ignorant “beauties”. Standing on the down-going elevator, I tried to walk upward constantly to realize a reverse “travel”. The passers-by became both my obstacles and my “scenery”. Shuttling through these “scenery” one after another, where could I arrive? The result seemed to be absurd: I was standing at the same place.
