In the fourth year of Qingyuan, Pingwei General Kou Yan was convicted of treason and his entire family was imprisoned. On the same day, Kou's legitimate daughter Kou Nuan had already entered the imperial city and became a member of the royal family when the imperial edict arrived at Kou's house because of her previous marriage to the royal family. Therefore, she was spared death. That day, the blood of the Kou family dyed every inch of the land of the Kou family red, and Kou Nui was given the title of 'lucky concubine' because of this incident, and she was jokingly called the 'surviving concubine'...
