It might be the book,"The Reborn Daughter's Counterattack". The female lead's name was Chu Ziyan. She had experienced many hardships, but after her rebirth, she worked hard and finally succeeded in turning the tables. She also participated in the selection of the palace and finally obtained the identity of the legitimate daughter. The entire story was smooth and dull, without too many heart-wrenching plots. It was very suitable to watch the complete story. I hope you like my recommendation. Muah ~
