"I am already old, one day in the hall of a public place, a man walked towards me." French female writer Marguerite Duras made a mysterious and perfect interpretation of the travel romance at the beginning of *The Lover*. The slightly bumpy carriage, the undulating deck, the enclosed cabin, the inevitable travel companions, the special mood of being in a foreign land... all these things incite romances during travels. Thus, some people exclaimed: "Romance is half of the journey."
