Su Yun, a female doctor of modern medicine, accidentally traveled through time and became a concubine of the Su Mansion in the Great Yong Kingdom. She was destined to marry into the family of a powerful minister due to fate. Faced with complex family rules, family plots, the fate of women on all sides, and the deep-seated crisis of her family and country, Su Yun uses modern rationality and strong adaptability to constantly break through her own barriers in the family fight and form her own "circle of friends." However, what seems to be a dispute over a single inner house gradually involves political struggles, family feuds, and the subtle changes in the fate of ancient women brought by her tiny modern thinking. Multiple threads advance together, including house fights, life and death decisions, personal growth, and turmoil in family and country. The intertwined advancement ultimately ends in the historical tide of Su Yun's self-realization and the transition between the old and the new after the end of the house.
