Set in the late Northern Song Dynasty, it tells the story of Yang Yinxiu, an introverted official daughter, who gradually awakens from the constraints of marriage and ethics after marrying Shen Zhilu, a prostitute. From purdah to Jinmingchi, from the prosperity of Bianjing to the storm of Jingkang, in a letter with apricot petals, a brave speech in a poetry club and a rescue operation in a siege, she broke free from the shackles of "a woman's duty" and finally found the strength to bloom for herself amidst the great changes of the times. This is an epic story of ancient women's growth, and it is also a gentle narrative that shines a light in a difficult situation.
