Su Wan, a modern workplace executive, traveled through time and became the adopted daughter of the Queen Mother of the Ning Dynasty. Shen Qingtang, the deposed queen of the cold palace, was sentenced to death by the scum emperor Xiao Jingheng. When she woke up, she was facing the crisis of poisoning and drinking. She relied on modern workplace negotiation skills and observation skills to resolve the crisis and stay in the cold palace. Then, using the resources of the cold palace (palace maids, former ministries), and through team management, data analysis, and public relations skills, we gradually exposed the conspiracy of the White Lotus Princess, slapped the suspicious character of Emperor Zha in the face, and collected evidence of Emperor Zha's murder of the late emperor and the common people. Finally, with the support of the Queen Mother and foreign ministers, the scum emperor was deposed, a new emperor was established, and the Queen Mother took control of the government. There is no golden finger in the whole process, relying on wisdom and means to achieve the counterattack from an abandoned concubine in the cold palace to the powerful one in the harem. The highlight focuses on every step of reversal, slap in the face and revenge.
