Auditioning and actually acting on a set are two different things. When you audition, you're in a room and you don't have anything to play with and you don't have anything physically in the room. Whereas on set, you have direction, you have costumes, and you have other actors to work with. It's a completely different thing.
试演和实际表演是两个不同的事情。 试镜时，您在房间里，没有东西可玩，房间里也没有任何东西。 场地上有方向，有服饰，还有其他演员可以合作。 这是完全不同的事情。
