She was the daughter of a Taifu. She became famous in the capital by singing about snow at the age of seven. She shocked the court with her policy essay at the age of fifteen, and was praised by the Holy Emperor as "having a daughter in the Ji family can bring peace to the country" - but she was always suppressed because of her identity as a woman. He is the eldest son of the General's Mansion. He draws talismans all day long and is treated as a joke by everyone in the capital.
The most sober decision Ji Wantang ever made in his life was to marry himself to the most useless man in the capital.
Because she is a woman, her ideas can be praised but not adopted; her talents can be praised but not used. Marry into a heavenly family and be a canary, marry into an aristocratic family and be a good housekeeper - these are all the choices given to her by the world. She wanted none of them. She wanted something she could hold in her hands.
So she took a fancy to Zhenbei General's Mansion. The Ji family is full of civil servants, but they have no military power, while the Gu family has a hundred thousand border troops. More importantly, Gu Changyuan, the eldest son of the Gu family, is a loser - he doesn't practice martial arts or study, and he draws talismans all day long. She even hoped that he would be as useless as possible. Only a man without ambition would be more controllable.
She thought she had picked a chess piece. It was only later that she discovered that the person she had chosen was the only one who could play chess with her.
Concept: A trapped wise man recognizes another trapped wise man. Then they made the same choice - to join forces and tear down the cage that trapped each other.
