Самгук саги
Jinseong is noted in the "Samguk Sagi" for her immoral and licentious conduct, ranging from taking bribes to bringing attractive men into the palace and committing lewd acts with them. She also carried on an affair with the high commander ("Gakgan") Wihong. The Samguk Sagi was written by Confucianists, who held a negative view of female rule, so the precise details therein should perhaps not be taken at face value.
