In the Dayong Dynasty, the imperial power was undercurrent, and the poor family was in trouble.
Former imperial censor Shen Jing was falsely accused and his entire family was executed. The only daughter, Shen Qingque, survived by chance. From then on, she changed her hair and transformed herself into a scholar from a poor family under the name "Shen Que". She sneaked into the capital carrying half a jade pendant engraved with the word "Qing" on her back. She has only one goal: to find the truth about her father's unjust case at Qingque Terrace, where literati gather and hide information.
When she first entered the capital, she unexpectedly got entangled with Xiao Heng, the seventh prince who was rumored to be addicted to poetry and wine. He seems to be laid back and gentle, and he is full of nonchalance when he flicks his folding fan, but in fact he has a hidden secret, secretly setting up a net to track down the culprits in the court; she is calm and intelligent, relying on calligraphy and mechanism skills, but in the mutual testing with him, she gradually loses her guard.
When the disguise of a poor scholar met the prince's constant pursuit, and when the clues in the investigation pointed to a conspiracy to seize the heir, the two went from being suspicious of each other to working together to solve the problem. On the Qingque stage, poetry and wine are sung and hidden secrets are hidden; under the palace wall, machinations and intrigues are intertwined with sincerity.
Half a jade pendant brings up an old case, and a chess game determines family, country and love. Can she overturn the family's verdict? Can he stabilize the government in troubled times? When the truth is revealed, how should these two people with different identities and different minds put their feelings in each other's heart?
