Gu Qingqian, a doctor of modern psychology, once traveled through time and became a "waste" princess of the Liang Dynasty, starting in hell mode. Faced with the exclusion of royal family members, the insidiousness of courtiers, and the troubles made by noble ladies, she said: The dignity of a psychology doctor cannot be violated! So what if there is no golden finger? She has the ability to see into people's hearts! The unruly cousin wants to use tears to gain sympathy? She analyzed micro-expressions and exposed it on the spot! The sinister cousin wants to use provocation to make her look embarrassed? She used cognitive behavioral therapy to break the opponent's psychological defense and make him doubt his life! The former obedient princess has changed. She has become a "human lie detector" and a "master of behavioral prediction". The overt and covert fights in the palace and the intrigues in the court became interesting "psychological games" in her eyes. She uses psychological suggestion and behavioral modification to manipulate those who once dismissed her. From a royal humiliation to a trusted advisor to the emperor, she not only cleared up her grievances, but also influenced the political structure of the Liang Dynasty step by step with her wisdom and charisma. Who says women can't participate in politics? Who says it's impossible to move forward without golden fingers? Gu Qingqian used her strength to prove: the brain is the strongest golden finger!
