During her three years in the cold palace, she learned the art of poison and also learned to keep her mouth shut.
On the day she left the palace, the Prime Minister's Mansion gave her to Prince Jing's Mansion, a sick man who could not live to be thirty.

On their wedding night, she knocked over his medicine bowl and wrote on the paper: Your illness is fake.

She wrote: I will help you pretend to be sick for the rest of your life. Please check one thing for me - how my mother died.
He held out his hand: deal.
She didn't hold it full, only her fingertips.

"Do you think," she wrote on the paper, "is it a disease or a medicine?"
