This novel was called "The Poisonous Shu Daughter: The Reborn Golden Princess". It was an ancient romance novel about the fight in the palace. It told the story of the female protagonist, Xie Qingyun, who was reborn when she was ten years old. She transformed into a Shu daughter to fight for power and wealth. She fought with her mother, the princess, and finally became the Golden Princess of the Phoenix Cry Mansion. It involved the double birth of a male and female protagonist. The female protagonist's mother was surnamed Chang, and so was the current empress dowager. I hope you like my recommendation. Muah ~
