From being a rough maid in the Yikun Palace to being a valet to Concubine Hua, from being an invisible intelligence operator in the harem to being the key pusher to overthrow the empress, Fuzi broke through the shackles of being a "palace maid" and was granted the title of "Princess Fu'an" by the emperor. But at the peak of her power, she saw clearly the nature of the Forbidden City - no matter how high the position of power was, it was still a prison. In the end, she retired with her friends and family and returned to her hometown in Suzhou to open an academy. She turned the historical wisdom of her past life and the experience of palace fighting in this life into a glimmer of light to protect the students at the bottom. She completed her nirvana from "chess piece" to "ruler" and truly took control of her own destiny.
