Among all of Taejo's wives and consorts, she held the highest title below the queen. This indicated that her father made an important contribution - to established the new Goryeo Dynasty and possibly that he was a behind-the-scenes figure who promoted Silla's noble wealth. Through her son, Heonmok became the great-grandmother of Queen Seonjeong.
