There were over 3000 concubines in the Emperor's court and every one competed for his attention; after all the only way for a concubine to be recognised as special was for her to deliver an heir. For a concubine to be allowed access to the Emperor her family would have to bribe the court eunuchs. They would select only the most beautiful concubines to be painted by the court portraitist. The Emperor would then choose the most beautiful.
As the war with Mongolia raged on, the Emperor began looking for a political solution. He decided he would make an offer of peace to the Mongolians. He told the Mongolians that he would offer one of his daughters to their Khan as a sign of goodwill.
