Przewalski's gazelle is a national first-class protected animal, with a body length of about 110 cm, a shoulder height of about 50 cm, black lips, white under the jaw, a yellowish brown body, and the white hairs on the buttocks will stand up and turn outward when frightened. Males have a pair of short black horns with the tip of the horn curved inward, so przewalski's gazelle is also known as the Chinese diagonal antelope.
In 1875, the Russian naturalist Przewalski discovered this unique Chinese animal in the Ordos steppe of Inner Mongolia, China, but it was not until 13 years later that it was officially named "Przewalski's Hartebeest".
Przewalski's gazelle is mainly distributed in Qinghai in China, inhabiting mountain basins and semi-desert areas around lakes. In Qinghai Province, przewalski's proto-antelope is a more typical desert and semi-desert ungulate, preferring to move in arid environments with vegetation types such as ephedra, mustard grass, moss grass, sand whip, sand needlegrass, wolf poison and artemisia, during which there are sand dunes tens of meters high, gentle slopes and open flat land, and the depths of the sand dunes are often used as their hiding places. Przewalski's gazelle inhabits a relatively flat semi-desert grassland, generally below 3400 meters above sea level, never reaching higher mountains, nor to the pure Gobi zone, so it is called "beach yellow sheep". Groups of several heads or dozens of heads often form large groups in winter. It feeds on sedges, grasses and other sandy plants.
