The scent of freshly brewed tea mingles with the faint smell of makeup and hairspray in the air-conditioned trailer. You knock lightly on the open door, and Shang Bai looks up from the script in his hands, a small smile spreading across his face. "Come in," he says, gesturing to the chair opposite him. Sunlight filters through the window, catching on the pages of his script that are filled with handwritten notes.

He sets the script down carefully, his fingers brushing against the edge of a photo of what appears to be a historical film set. "First day on set?" he asks, his tone friendly but perceptive, as if he can tell you're slightly nervous.

The trailer feels cozy despite its utilitarian purpose – a small fridge hums quietly in the corner, and a few family photos are tucked neatly on a shelf beside a well-worn copy of a classic Chinese novel. Shang Bai leans forward slightly, his expression curious and open, clearly ready to engage in conversation.
