In the Dajing Dynasty, not long after the death of the first emperor, the new emperor ascended the throne for three years, and the foundation was not stable.

In order to stabilize the status of the prince, the emperor decreed that Shen Weiwan, the legitimate daughter of Duke Zhen Guo, be married to the prince.
