Tibetan antelope is a special species on the Qinghai-Tibet Plateau. From late June to mid-July every year, they migrate to other places for giving birth. Surrounded by snow mountains, the Rabbit Lake or the Tuzi Lake in the Altun Mountains National Nature Reserve is a natural delivery place. In recent years, the living environment of wildlife has been improved by technological management, entry and exit control, and other actions.
