Xianshu was a Chinese term that referred to those reading materials that did not pay attention to the development of the plot or the creation of characters, but only pursued relaxation, humor, and leisure. In the field of novels, leisure books usually referred to novels that were more relaxed, casual, simple, and had fewer characters, such as essays, martial arts novels, science fiction, and so on.
The word "leisure" in leisure books meant that these novels did not pay attention to utilitarian-oriented writing. They were not written to make money, improve social status, or obtain other purposes. Instead, they were written to seek a relaxed, free, and enjoyable reading experience. Therefore, leisure books often had relatively relaxed, humorous, absurd, bizarre plots, as well as rich imagination and fantasy elements.
A leisure book refers to a type of book that is not very important or has no special meaning. It is usually written for entertainment or to kill time. In novels, the word idle usually referred to some unimportant plot, characters, or conversations that were rarely used as part of the main plot. They were only used to make the reader feel relaxed and happy when reading.
