Lin Xiaoxiao, a modern working woman, dresses up as an ancient lady. In order to save her family, she is forced to disguise herself as a man and pass the imperial examination for her brother. After entering the court, she relied on modern knowledge to become a "drama expert": she taught SWOT analysis to the six-year-old emperor on border defense, used "hunger marketing" to raise birthday gifts for the Queen Mother, and walked on thin ice under the watchful eyes of King Ning's party. From the "Tang Hua Lang" to the royal celebrity, she uses economic thinking to solve the financial crisis with her left hand, and draws the power map of the court with her right hand, dealing with young generals, romantic talents, and shady princes. And the secret of a woman disguising herself as a man is like a hanging sword, constantly testing the ultimate acting skills of this first "actor queen"-level assistant in Daqian.
