This book is one of the novella collections of Mo Yan, the winner of the 2012 Nobel Prize for Literature, and includes three works. "Explosion" describes the process of "I" taking my wife to the hospital for an abortion. However, during this process, there was a turbulent and open atmosphere inside and outside the delivery room, in the sky and on the earth. It shows the "explosion" of the contradiction between old and new moral concepts. It can even be regarded as an "explosion" of information from various eras. "Happiness" tells the story of Yongle, a young man born in a poor family in rural Gaomi County. Like thousands of rural children, he hoped to escape from farming and escape poverty and backwardness through the college entrance examination. However, he failed the college entrance examination five times. When his hope was in vain, he had to escape from home and embark on the road of "joy". "River in the Rain" is Mo Yan's earliest novella, which shows Mo Yan's early style. These novellas have distinct artistic styles and unique characteristics. They can be called very exciting "small novels" in terms of content and length. The novels use "deviant" imagination to write the subtle human nature and profound spiritual history.
