Chu Moer was made the empress by the emperor. In order to give Chu Moer the exclusive favor, the emperor dismissed the entire harem. For several years, Chu Moer was the only one in the harem. However, Chu Moer had several miscarriages due to physical reasons, and she had not been able to give birth to a heir for the emperor for several years. But in the emperor's mind, as long as Chu Moer was fine, nothing else mattered. The ministers of the palace repeatedly wrote to the emperor, saying that the country cannot be without an empress, and hoped that the emperor could fill the harem, but they were all rejected by the emperor. At this time, the former queen's sister revealed her dark side and planned to retaliate against the queen and the emperor.
