This book tells the story of Gu Heng, a young boy, who is wanton in making public and surprised. Unexpectedly, an accident took away his frivolous confidence. At that time, Yu Qing, with her ex-boyfriend's deception and endless accusations and abuse around her, hurried out of the metropolis, like fleeing a swamp that ate people. The appearance of Qing Yu has become a collection of poems imagined by Gu Heng in a pale and hopeless world.
