During the Hongzhi period, Taihu Lake suffered from repeated flooding. Bai Jingzhou, a flood control scholar, and the mysterious boy "Zhao Qing" met in Xishan due to a data dispute. Bai Jingzhou adheres to the principle of "to control water, stop it", but Zhao Qing asked: "Are you treating the water or the people?"... The data error is four points, which can be the difference between life and death; Under the polders, there are corrupt account books and treasonous secret letters buried; why did she, disguised as a man, risk her life to investigate the case? And he refused to marry twice, but he didn't know that he had already fallen in love with "him". When the raging waves of Taihu Lake stir up conspiracy, can they protect each other and the people in the torrent?
The intention: to use water control as a mirror to see the suffering of people's livelihood, the corruption of officialdom and the glory of human nature; to use the ambition of a pair of jade men to write the ideal persistence and love of "Don't teach Li Shu to burst into tears".
