a dialect of the Baima people, means auspicious mask dance, commonly known as "Twelve Phases Dance" in Chinese. It originated from the primitive period when the Baima people worshipped "all things have spirits". It is a fusion of Diqiang culture and Tibetan culture, and has a certain sacrificial nature. The characteristics of its animal-like dance show that it should be one of the remains of the ancient "hundred beasts leading the dance". The dance is generally performed by seven, nine, or eleven people. The first set of movements in its dance combination is called "Niu", which is generally performed in large-scale sacrificial activities and in front of gods, including sacrificing to ancestors and mountains; the second set of movements is called "Ga", which is generally performed in the field; the third set of movements is called "Yang", which is a set of blessing dances, mostly used to visit villages, worship elders, and wish each other. "Ali Ga", commonly known as jumping little ghosts in Chinese, is a duet dance, representing a male and a female, in which the "female" side is a man dressed as a woman. The whole dance shows the scene of love between Baima men and women. The leading dancer wears a lion head mask, which is known as the king of beasts and the king of the forest. The animal masks worn by the other dancers are, according to the custom, an ox head, a tiger head, a dragon head, a leopard head, a snake head, a chicken head, two little ghosts, and two big ghosts. The dance is of great research value for the origin, development, evolution, and formation of dance rituals of primitive animal-like dance. The dance combination is based on the stepping of circle dance and the tiptoeing of flowers. The basic rhythm of the dance is mainly based on stepping, squatting with the calf in a circle, and jumping and turning in circles. Combined with the rough and mysterious upper limb movements, it vividly expresses the form of the animals played, reflecting the unique aesthetic consciousness of the Baima people. The overall ritual of the dance fully reflects the Baima people's worship of nature and conveys their wish to maintain the peaceful social and ecological environment of the local area.
