Every year tens of thousands of endemic Tibetan antelope or "chiru" undertake a big migration from their breeding grounds in the valleys of China's Qinghai province to their calving grounds on the high and remote Quighai-Tibet plateau. It's one of China's greatest wildlife events, full of drama, spectacle and surprise, and all set in a breathtaking landscape.
