ALTUN MOUNTAINS, July 15 (Xinhua) — The rabbit lake district of the Xinjiang Altun Mountains National Nature Reserve has an average altitude of about 5,000 meters. Surrounded by snow mountains, the district is a natural shelter for Tibetan antelopes to avoid their natural enemies. The animal enters its peak season of reproducing in July. Thousands of baby Tibetan antelopes are born here every year. Guided by their mothers, the babies will learn basic living skills such as standing, walking and running within half an hour after birth. Tibetan antelopes are under the first-class protection of the country.
