Queen Sun of Emperor Xuan Zong and Politics of Middle Ming Dynasty

In the historical literatures of Ming dynasty,Queen Sun of Emperor Xuan Zong was respected.Through my careful study,these literatures are misleading and need clarification.This paper is divided into three parts to discuss the negative influence of Queen Sun in the politics of middle Ming dynasty.First,it narrates Sun's pursuit of Golden Cimelia and abolishing the first queen,which discovers her plots to turn the Ming dynasty into a corrupt government.Then it states that in the period of Tumu Accident,Sun hindered the enthronement of Prince Zhu Qiyu and the preparation for the struggle against the attack of Wala soldiers.At last the paper narrates Sun's negative influence in the Royal Door Coup d'Etat,which led to the retreat of Ming dynasty.
