Can you recommend a romance novel?

I remember that the female lead is called Yu Pinyan, and she has a sister called Yu Pinting. Pinyan transmigrated and seems to be an archaeologist. In the middle of the story, the female protagonist was framed by the palace and later rescued by the emperor's brother. The female protagonist was pregnant. Later on, the Emperor went on a tour to pay homage to her and went to his brother's house as a guest. He heard the familiar sound of the zither and realized that the female protagonist was not dead. She had even given birth to two children for him. The Emperor wanted to bring the female protagonist back to the palace and make her the Empress.
This novel was a long time ago. It seemed to be 14 years ago.
