(A stupid piece of writing, the title of the book was chosen by my girlfriend)
The Yuchi family gave birth to two marquises, who were stationed in the western border of Qin and the South China Sea to guard its territory and ensure the peace and prosperity of Qin. The late emperor re-appointed two marquises and granted them military power. When the new emperor ascended the throne, he was wary, so he granted marriage to the second marquis of the Yuchi family. The person he married was the eldest daughter of General Song. The Song family was dissatisfied with the new emperor's actions, but the imperial edict could not be violated. The Song family's daughter was not dissatisfied, but his younger brother did not allow it. On the day of the wedding, the second son of the Song family stunned his eldest sister with poison, married in her stead, put on a red hijab, got on a rickety sedan, and entered the gate of the Northern Xinjiang Marquis Mansion.
