Ding Dingdang was born in the countryside. He disliked red makeup and favored weapons since he was a child. He learned civil and military tactics, but ran away from home because he refused to marry a rich man. On the way, she accidentally rescued the second prince Zhao Chen who was ambushed by assassins. At that time, the old emperor was testing the three princes with disaster relief. Zhao Chen went deep into Zhongzhou, where the disaster was most severe. However, he was plotted by his brothers because of his kindness, and all his entourage was lost. Fortunately, he was rescued by Ding Dingdang.
Ding Dingdang, who disguised herself as a man, was moved by Zhao Chen's kindness and magnanimity, and stayed as "Ding Dang, the traveling scholar" to become his bodyguard and staff. She not only helped him resolve assassination crises one after another, but also gave him advice to win the approval of the old emperor.
During this period, the eldest princess's enthusiastic pursuit of Ding Dang, who was disguised as a man, caused many jokes, but she also unexpectedly became the guardian of her daughter's body. And Zhao Chen has long admired this wise and brave "brother" after fighting side by side and relying on life and death for countless times.
After Zhao Chen ascended the throne, Ding Dingdang's identity as a woman was exposed because she refused to be promoted to an official position, and the relationship between the two also underwent subtle changes. With the help of Ding Dingdang, Zhao Chen finally swept Liuhe and unified the world. Finally, Ding Dingdang and Zhao Chen got married, and the story ended successfully.
