Zheng Yunzhao, the youngest household doctor in the Chu Dynasty, was a "deer" official known for his gentleness. He looks as gentle as jade, but in fact he is thoughtful and has a special golden finger - the "historical eye" that can see the truth of history by touching the fragments of ancient books.
In this seemingly prosperous Chu Dynasty, there are actually undercurrents. Above the court, the conservatives headed by Prime Minister Wang Chong controlled the government, and the idea of favoring boys over girls was deeply rooted. However, Zheng Yunzhao proposed a change that shocked the government and the public - the establishment of a women's imperial examination, breaking the thousand-year restriction that women were not allowed to enter officialdom.
His reforms touched the interests of too many people, and the first to bear the brunt was his biological mother, Mrs. Zheng. This noble lady from a prominent family has not wanted to see her son since she was a child. Instead, she pinned all her hopes on her younger son Zheng Yunhao, who was a playboy. In her eyes, Zheng Yunzhao's reforms were a challenge to the ancestral rules and a shame that made her unable to hold her head high in the circle of ladies.
Zheng Yunzhao's sister Zheng Yunqing, a talented but unsuccessful girl, became the first beneficiary and the first victim of this reform. When the green tea-type Zheng Yunhao took advantage of his mother's favor and designed to frame his sister, Zheng Yunzhao had to choose between family affection and ideals.
The tide of history has surged. Can Zheng Yunzhao, as gentle as a deer, fight his way out in this game of power and ideas?
