I recommend the novel "The Rebirth of the Phoenix's Path." The female lead was also called Yan 'er, and she also had a red birthmark on her face. In her previous life, she was abandoned by a scumbag and schemed to death by her stepsister. After her rebirth, she began to fight for revenge. After meeting the cold and aloof prince, she gradually revealed her medical skills and intelligence. I hope you like this novel. Muah ~
