Film makers in southwest China's Tibet Autonomous Region have begun shooting an impressive five-minute film "Heavenly Tibet," showcasing breath-taking scenery on the rooftop of the world and its blueprint for the future.

The film will be screened around the clock at Tibet's 600-square-meter exhibition in China's joint provincial pavilion at World Expo 2010.

It will be aired after the Expo as a promotional film.

The world's highest railway, the Qinghai-Tibet Railway, will be highlighted to show the superb ecology.
