Su Xiaoman, a graduate student in the Department of History, accidentally touched a mutilated phoenix jade pendant when visiting the Qianlong special exhibition in the Forbidden City. She traveled back in time to the Qianlong period of the Qing Dynasty and became the lowest palace maid in Xinzheku. With modern knowledge, she improved the laundry method and made a water purification device, which attracted the attention of the fifth elder brother Yongqi, and was promoted as a companion maid.
In the deep palace, she used medical skills to treat Yongqi's stubborn illness, and used modern ideas to influence the prince who died young in history, and the two gradually fell in love. However, the conspiracy between the Queen and He Shen, the mystery of Ziwei's life experience, and the secret of the Phoenix Jade Pendant followed one after another. When Su Xiaoman was framed for witchcraft and sentenced to death at the stake, the seriously injured Yongqi rescued her from the execution ground. The two jade pendants merged into one, triggering a space-time phenomenon - she had to make a choice between returning to modern times and staying in the Qing Dynasty...
Concept: True love and free will can transcend time, space and destiny, and rewrite the established trajectory of history.
