The tiger patterned ceramic tablets unearthed in Gansu Province are the physical objects of totem worship. Yi, Naxi, Lisu and other ethnic groups to the black tiger as a totem. The Ba people and their descendants in the southwest region of the Tujia and Pumi, the Bai people to the white tiger as a totem. The Yi people use the twelve phases of the solar calendar, with the tiger as the first. The Dance of the Twelve Beasts and Gods is still preserved today. This is performed by a witch, and the dance culminates in the performance of the tiger god descending and pouncing on domestic animals, so one can imagine the original Tiger Totem Dance. In the Yi "Beat Song", the dance is accompanied by the chanting of "Luo Li Luo, Luo Li Luo! meaning "Tiger, tiger, tiger, tiger!"
