The Y-Eunuch Dance was a fictional plot in which a eunuch danced in front of the emperor or the protagonist to increase the entertainment effect of the readers. This plot often appeared in some harem novels or eunuch novels. Because eunuchs were generally infertile, it was often used by authors to enhance the tension and interest of the story. However, it should be noted that such fictional plots are only fictional elements in the creation of novels and should not be regarded as real history or events.
