But according to the lyrics of the song, it should be the Western Qiang people (Tibetans)
The Qiang people used to be a great ancient oriental tribe, formed in the region of the Qinghai-Tibetan Plateau, which is the ancient name of the Tibetans. They had sheep as their totem (earlier, they were mainly engaged in animal husbandry). The written records of the Qiang were found in the Shang Dynasty. Yin and Shang oracle bones frequently appear in the word "Qiang".
