The story happened in the early 1990s, when the reform and opening up had just passed a decade, and the Internet and mobile phones had not been popularized. At that time, the sky was pure blue, the clouds were pure white, and the water was clear. Even the men and women who came and went on the street, their faces seemed to be attached with a layer of hymen, reflecting pure white in the sun. But the world is like this, angels because of the devil has its meaning of existence, black against white, day and night entangled. When people come to an environment of their own ignorance, they will naturally have a kind of nervous psychology. With the deepening of fear, it will lose its original ability and become a cake sheep to be slaughtered.
