The imperial power was at its peak and the undercurrent in the court was turbulent. The young God of War Prince Xiao Yu has a large number of troops and has made great achievements in battle, but his great achievements have aroused suspicion in the court. In order to appease this cold-faced powerful minister, the emperor granted a marriage to Prince Xiao, who wielded power in the court, and the legitimate daughter of the Hou clan. The original bride was Su Wanrou, the legitimate daughter of the Marquis of Zhenyuan. Unexpectedly, she suddenly became ill on the eve of the wedding (actually running away from the marriage), and her half-sister Su Liyue was forced to marry in her place. In the big red sedan chair, Su Liyue was married into the palace with a wedding scarf on her face. From then on, a legend of marriage first and love later unfolded.
