When she first entered the palace, she was harshly treated by the nuns in charge and framed by her peers. She resolved the crisis with her agility, and secretly observed the behavior of the concubines by ghostwriting for the empresses of various palaces.

From then on, she was involved in the struggle for succession. Facing the queen's poisonous wine, the frame-up of her favorite concubine, and the pursuit of old enemies from the previous dynasty, she solved the problems one by one with the method of "repaying him with his own way", wandering between the emperor's mind and the power struggle in the harem, and finally grew from a sinful maid in Yeting to the master of the middle palace in the mother's world. In the process, she also uncovered the truth about her father's case and restored her family's innocence. There is no golden finger in the whole drama, and the exciting points are concentrated in famous and famous scenes such as "anti-kill in desperate situation", "outsmarting the serial plan" and "defeating the strong with the weak".
