Su Qingyuan, a doctor of modern Chinese language and literature, accidentally traveled through time while researching a rare rare idiom, and became the frail and sickly fifth princess of the Dajing Dynasty, whose father did not care for her and whose mother did not love her. She discovered that people in this dynasty had little understanding of "idioms", so she used idioms as weapons to find a way out for herself and the fifth prince in the turbulent harem and court, and eventually helped her husband ascend to the throne and become a legendary queen.
