Rangers rescue baby Tibetan antelopes on the 'roof of the world'
The Hoh Xil National Nature Reserve in northwest China's Qinghai Province is home to wild animals, including the Tibetan antelope. Female antelopes migrate from different regions to give birth here every year. During the four-month migration season, rangers in Qinghai work to create a safe environment for the creatures and rescue calves in danger. A conservation worker shared exclusive footage from their rescue mission this year with CGTN.
