It implements the ultimate ideal of Zhang Zai's "Four Sentences of Hengqu" in the Northern Song Dynasty, breaks the narrow pattern of the traditional fairy tale of "singlely achieving immortality, killing and conquering the road", and uses the troubled times of the fairy tale as a carrier to interpret the fateful struggle between mortals and monks, the ultimate game between selfishness and the great road, and the tragic song of a lonely and innocent child who saves the world. There is no absolute opposition between good and evil in the book, only different attitudes and choices. It takes compassion for the common people, adhering to the right path, continuing the cultural context, and eternal peace as the ultimate belief, interpreting the spiritual backbone of Chinese literati and lofty ideals spanning the ages.
