What is the relationship with Xia?

It is reported that in the TV series Princess Zhu Huan, Xia is not related by blood, but looks a bit like her.

In the play, the emperor met a famous prostitute in the south of the Yangtze River during his southern tour, and his temperament was similar to that of Xia. Therefore, the emperor fell in love with her at first sight, and even tried to take her back to the palace despite the obstruction of the queen and the queen mother. In order to stop the emperor, the queen had an argument and cut her hair.

After Wei Zi took the initiative to find it, he told him the story of Xia and the emperor, and told her that the emperor liked her only because she looked like Xia. Later, Xia Yingying took the initiative to reject the emperor and stayed in Jiangnan.
