“天书”，在历史传说中其最初的来源是对文字、经书等文化突出代表物的崇拜，后来又受到符命之说的影响，在政治斗争中它有着为打破世袭统治、抢夺最高权利服务的功能，同时它又为下层民众所用，起着促进改变黑暗现实、鼓励反抗斗争的作用；古代小说家将其作为素材进行创作时也同样将其喻意吸收进小说，在表现歌颂造反的主题和组织小说情节方面起着重要的作用。 In the historical legends, “the first book” originated from the worship of prominent cultural objects such as texts, scriptures, etc., and was subsequently influenced by the theory of life. In the political struggle, the Bible had the function of breaking down hereditary rule and robbing the supreme power It also plays the role of promoting the change of the dark reality and encouraging the struggle against it. When the ancient novelists used it as a material to create the novel, it also metaphorically absorbed it into the novel and expressed the theme of rebelling against rebellion And organize the plot of the novel plays an important role.
