This has become an unwritten rule in the industry. After all, to have a top director take the time to teach someone how to act, particularly a clueless newbie... it's basically impossible.
If that really were the case, the film wouldn't even need to be shot.
If she turned out to be one of those talentless, attention-seeking internet celebrities, Xue Fan wouldn't even bother.
But after meeting Yun Qiluo, he found that this young girl was different from what he imagined. Giving her a little guidance wouldn't hurt.
The main thing was, she looked good, clean and fresh, which made it easy for him to talk to her, so he didn't mind spending a bit of extra time giving her some tips.
Of course, it's just a few extra words. How much she can learn is up to her, and it's still impossible for Xue Fan to have the time to teach her step by step.
He even prepared himself; even if in the end she acted like a piece of wood, it would be fine for her to obediently be just a pretty face.
