Relying on her understanding of the history of the late Ming Dynasty, she tried to change Chongzhen's fate of subjugation and her own situation. However, she fell in love with the suspicious and diligent Chongzhen in the whirlpool of power and intrigue. Finally, she fell into the fateful predicament of "knowing the outcome but being powerless to change the fate". She had to choose between life and death, love and hate when the country was destroyed.
