In early November 2012, the first snowfall of this winter fell in Beijing. On this cold weekend afternoon, I calmed down and finally decided to write down the story that had been lingering in my mind. I have no way of knowing the true appearance of that era, but no matter how the world changes, people's pursuit and yearning for love and freedom remain the same. In order to live the life they want, the people in the story chose different methods and different paths. Maybe these are not right or wrong, but they will all become a wisp of smoke in the vast history a hundred years later. But everything has a cause and effect, I just want to be clear in my heart.
