The story takes place in the late Yun period. The Yun Dynasty is a fictional dynasty with no real prototype.
During the Dayun period, the emperor valued the distinction between direct descendants and concubines.
Although Fu Yao was the eldest daughter of the royal family, she was not taken seriously because she was born in February. She had been fostered with her maternal grandmother in the palace of Zhongliang City since she was a child. If the news of the new emperor's enthronement had not come from the palace, the imperial grandmother who loved Fu Yao would not have been able to find the support to let Fu Yao return to the palace in a dignified manner.
