Zheng Lixia, the daughter of a down-and-out scholar, entered the palace in order to seek "establishment". She regarded the harem as a workplace and made a living by making pickles, abacus and other market skills. She adheres to the workplace philosophy of "no fight or big fight". She made a decisive comeback in Feng Yin's frame-up case and used the "rat hole" to reverse the testimony; she refused to be promoted and became queen, but unexpectedly jumped multiple levels in a row. In the face of the turmoil, rumors and the emperor's sincerity, she always remained sober, and eventually became the only person in the emperor who could take off her disguise and find her own stability.
