Dangong dance in An County appeared in the late Qing Dynasty. After liberation, Dangong dance gradually became more frequent. In rural areas, some patients could not be cured after a long time of treatment, so they asked Dangong to perform rituals to drive away ghosts and evil spirits and pray for peace; the "Dangong dance" ritual is ancient, sometimes dancing, sometimes jumping, sometimes talking, sometimes singing, sometimes angry, or a combination of both. The lyrics are rich in content, and the "Shangtan Sutra" recited and sung reflects the historical culture, philosophical thoughts and moral concepts of the region. The main props are the teacher's knife, token, sheepskin drum and hexagrams made of ox horns. It is also the product of the mutual influence of the Qiang "Shibi Culture" and Buddhism, Taoism, local opera, etc. Dangong rituals are all charged, and there is a saying that "I would rather give you the throne than give away Buddhist mantras." Later, it was said that the folk witchcraft community (Dangong troupe) in the northwest of Sichuan was relatively active. The witches often dispersed and gathered according to different situations, went from village to village, and were flexible and self-contained. During the Republic of China, a group of "Duangong Opera Troupes" represented by Wang Laosi and Wang Laowu were active in Anxian County and surrounding counties and cities. In terms of form, "Duangong Opera Troupes" are similar to Sichuan Opera Troupes, but their organizational form is slightly different from that of Sichuan Opera Troupes. For example, Sichuan Opera Troupes are mostly "professional" troupes, while Duangong Opera Troupes are mostly "amateur" troupes. The instrument configuration is basically the same as that of Sichuan Opera, but the repertoire is slightly different. The singing style of "Duangong Opera Troupes" is mostly based on Sichuan Opera's "lantern opera" and "gaoqiang" as the backbone tones, and occasionally some folk "fortune-telling tunes" are also interspersed. In order to survive, "Duangong Opera Troupes" also have to travel around the countryside, attend temple fairs, sing operas, and participate in some local folk activities, such as setting up altars for sacrifice, spiritual officials guarding the altar, and gods going out on tour, etc., and sometimes participate in some special "Tanghui" performances. Except for the troupe owner, wizards and a few backbones, the rest of the people are mostly temporary combinations. They perform operas and dance Duangong. They usually work as farmers or merchants. They come when they are needed and leave when they are done.
