The princess of Northern Yan Dynasty, {Feng Shuyi}, was taken into the palace of Northern Wei Dynasty and became a slave after the fall of the country. She was smart and quick-witted, and managed every step of the way in the deep palace. She won the favor of Emperor Wencheng Tuoba Jun, and was promoted to a noble concubine. She worked with the emperor to stabilize the harem and secretly helped the government. Emperor Wencheng died suddenly, and the young emperor Tuoba Hong succeeded to the throne. The powerful minister Yihun became domineering, and rebellions broke out in the border areas. Feng Shuyi came to the court as the Queen Mother to listen to the government, used thunderous means to eradicate traitors, quell rebellions, and stabilize the turbulent Northern Wei Dynasty. She promoted sinicization, encouraged teaching and farming, established education, and reformed government, and her national power became stronger and stronger. However, as Tuobahong came of age, the mother and son gradually developed rifts over power and political opinions. Feng Shuyi had no choice but to depose the emperor and install her grandson Tuobahong on the throne. She continued to assist Emperor Xiaowen in deepening reforms and promoting national integration, and eventually became a legend. After her death, she was posthumously titled "Civilized Empress Dowager", and her achievements will be recorded in history forever.
