Zhang Guifei gave birth to a baby girl. In order to keep her position in the palace, she exchanged her baby girl with a baby boy born to a college girl at the same time. Later, the boy became the present prince and Zhang Guifei became the empress dowager.
The parties are very disgusted with this, but there is nothing they can do. So he abandoned Zhang Guifei's own flesh and blood at the gate of the brothel Baihualou in Yangzhou. Eight years later, the real princess was brought up by Qinglong girl, and the baby girl of that year also became a cheerful girl.
