Budorcas taxicolor is a member of the subfamily Lambinae in the family Bovidae, belonging to the genus Takin.

      Takins are herbivorous animals widely found in the central eastern part of the Himalayas, as well as in the Hengduan Mountains, Micang Mountains, and Qinling Mountains at elevations of 2000-4000 meters. They are also rare animals found only in five Asian countries, including China, India, Nepal, Bhutan, and Myanmar. The distribution area is roughly between 25 degrees 15 minutes north latitude and 34 degrees 19 minutes north longitude, and 97 degrees 30 minutes east longitude and 109 degrees 30 minutes east longitude. There are four subspecies of takin, namely, Bhutan subspecies distributed in the Himalayas, Gaoligong subspecies distributed in the Tibetan Yunnan area of Hengduan Shanxi, Qinling subspecies distributed in the Qinling Mountains of Micang Mountain, and Budorcas Taxicolor tibetana distributed in the Gongga Mountains of Sichuan and Baoxing of Ya'an. Takins are first-class protected animals in China, listed as endangered species in the Red Book published by China, and listed as precious animals in the Red Book published by the International Union for Conservation of Nature.

       Takins have thick limbs and a tall body shape. Adult individuals can reach a body length of about 1.8-2 meters, with a maximum shoulder height of over 120 centimeters. Their weight is mostly around 200-300 kilograms, with a maximum of 1000 kilograms. Therefore, the appearance of takins is more like that of cows, and in Hailuogou, locals call them "bison". The spine of the "Bison" in Hailuogou is raised like a brown bear, its face is tense like a moose, its horns look like both sheep and cattle, especially like a horned horse. Its hind legs are slightly tilted like a spotted hyena, its snout and tail resemble a goat, its limbs are short and thick, and its appearance resembles that of a cow. Therefore, some researchers call it the "Six Nos".

       Hailuogou Takins are mainly distributed in Hailuogou and the surrounding forest and shrub grass areas between 2000 and 4000 meters above sea level. Pineapple, Qianghuo, and fresh and tender leaves are all their favorite foods. They often come to the hot springs to drink water because the hot spring water contains trace elements and minerals, including salt, which are essential nutrients in the body of takins.

       On a visit to the No. 2 Glacier on the right side of Hailuogou Glacier at an altitude of 5000 meters, we unexpectedly encountered a group of "bison" on a slope at an altitude of 4000 meters. At that time, these beautiful creatures in Hailuogou were sleeping and sunbathing in a lush Qianghuo grassland. As soon as they heard someone coming, they lazily stood up. A few little takins still couldn't forget to gnaw on the tender moss tips of the Qianghuo grass around them. Just as I raised my camera and didn't have time to press the shutter button, suddenly, they heard the alarm signal of the "cow" and disappeared into the dense shrubs nearby in the blink of an eye. When we arrived, we only saw large areas of Qianghuo grass crushed by takins and cow dung still emitting heat.
