Ganzi Tibetan opera in Sichuan, known as "Ajlam" in Tibetan, traces its origins to Tibetan religious art in the 8th century. The performance of Tibetan opera is divided into three parts, namely "Dun", "Xiong" and "Tashi". "Dun" is the opening performance of the song and dance of the gods; "Xiong" mainly performs the legend of the main opera; "Tashi" means blessing and auspiciousness. There is only one set of costumes for Tibetan opera from beginning to end, and the actors do not wear makeup, but mainly wear masks to perform.
