The sky in Lhasa is gradually turning from blue to red, then to gray and dark.

On the south bank of the Lhasa River, the mountains are covered in green. Stars light up a stage that is set for a story which is over 1,300 years old.

On the stage, the actors are still perfecting their rehearsal, while under the stage, a Tibetan woman with a microphone stands with her gaze fixated on the actors, from time to time demonstrating a dance move.

She will speak through the intercom in a moment, then talk with a person taking notes to the side.

With this being her sixth year of performances, she is familiar with everything in the production, from the rehearsal, to settings, lighting, props, costumes, dance steps, and movements, but she still stares intently at the actors on stage, not letting anything go unnoticed.

Her name is Langdon Bekyi, and she is a first-grade director of China and the deputy director and artistic director of the Princess Wencheng large-scale epic drama.

From the dancers to the director, she understands that the details can determine success or failure.
