A time travel made Su Qingyan the deposed queen of Dajing's cold palace. In a desperate situation, she relied on tenacity and intelligence to first clear her wrongdoing and get out of trouble, and then take charge of the harem. In this palace, she not only has to deal with complex power struggles, but also assists the king in putting down rebellions such as the Liu family and the remnants of the previous dynasty.
Su Qingyan has the world at heart. She implements a series of people's livelihood reform measures such as government education, water conservancy, trade, and Huiminfang, and is committed to making the people of Dajing live and work in peace and contentment. She gradually grew up from an abandoned queen to a virtuous queen who could influence the destiny of the country. She used her wisdom and courage to lay the foundation for the prosperous era of Dajing.
In the end, Dajing entered a prosperous era, and Su Qingyan also left his name in history.
