The female lead in 'The Most Beautiful Doctor' was a character that showed growth. The story would show the great lengths that she would go through to go from being a young girl fresh out of school to becoming a chief physician in the end.
This was a very layered role and required the actor to act out her temperaments during the many stages of her life.
At the beginning, the director had still been doubtful of Fang Mo'er. It was not until he had seen her in "Hua Mulan" where she had gone from impersonating a boy who would become a male soldier at a military camp to becoming a general.
Fang Mo'er had acted very well at every stage.
After watching the movie, the director had been even more certain that Fang Mo'er was the right person to play the female lead in "The Most Beautiful Doctor".
Since the actor who had been cast as the male lead was also there and both of them had read the script, the director decided to let them act together.
