A thunderstorm turned the fate of Ye Mingzhu, the princess of the Hou family, and Chen Yanzhi, a scholar from a poor family, upside down. Golden branches and jade leaves are trapped in the body of a common man, and a student in a poor window falls into a splendid cage. Ye Mingzhu, under the identity of Chen Yanzhi, broke into the imperial examination venue that was originally a male world with a pen in hand, but encountered the humiliation of "wet nurse examination" and the mystery of "stained ink scroll"; Chen Yanzhi, wearing Ye Mingzhu's gorgeous clothes, moved the abacus in the deep house of the Hou Mansion, facing the strict barrier of "male master". One was swaying in the examination room, innovating anti-counterfeiting techniques with "Kao Gong Ji" and advocating "transferring without name"; the other was making waves in the business world, using "assembly line division of labor" and "integrity contract" to break prejudices. They never hated each other's world, but used their own strengths to break the deadlock. When the siphon timepiece designed by Ye Mingzhu came into being in the palace examination, and when Chen Yanzhi's business wisdom won praise from the whole city, a reconstruction of the value of talent, learning and gender quietly came - the soul is not noble or low, and talent is the standard. Let's see how this pair of dislocated souls work together to break through the shackles, open the door of "female household science" for women all over the world, and write a heart-stirring song of equal rights.
