【明報專訊】In front of the cameras, Jenny is a beautiful princess. "Everything looks lovely," Jenny said, "but it's not real. Behind the scenes I'm on a stage (舞台) performing in a role in a film." While this began as a theatrical term referring to the backstage (後台), it is now used to describe something of importance out of public view or knowledge. "People think Jenny is a great actress, but behind the scenes there are a dozen people coaching (訓練、指導) her."
