When life gets us down, literary books can offer us a world on a higher plane of existence, which is better than the real world. For example, in the books, the water may be more pellucid than that of the real world, and the sky bluer; there is no perfect love story in real life, but in literature, the love story of Liang Shanbo and Zhu Yingtai (also called the Butterfly Lovers), and the story of Romeo and Juliet can last forever. Therefore, reading books will soothe the frustration and roughness that exist in our everyday life.
