Bimoism
Bimoism (, Yi: ) is the indigenous religion of the Yi people, the largest ethnic group in Yunnan after the Han Chinese. It takes its name from the "bimo", shaman-priests who are also masters of Yi language and scriptures, wearing distinctive black robes and large hats. Since the 1980s, with the loosening of religion restrictions in China, Bimoism has undergone a revitalisation. In 1996, the Bimo Culture Research Center was founded. In the early 2010s, the government of China has helped the revival of the Bimoist faith through the construction of large temples and ceremonial complexes. Priesthood. The "bimo" priests . Bimo officiate at births, funerals, weddings and holidays. They are often seen along the street consulting ancient scripts. The "bimo", once considered by the Chinese government to be promoting a "backwards religion", are now being promoted as ambassadors of Yi culture. They organise large-scale rituals for the yearly Torch Festival. The "suni" priests. Nosu Bimoism, the religion of the Nosu or Nuosu subgroup of the Yi, distinguishes two sorts of shamans: the "bimo" and the "suni", respectively hereditary and ordained priests. One can become bimo by patrilineal descent after a time of apprenticeship or formally acknowledging an old bimo  as the teacher. A suni must be elected. Bimo can read Yi scripts while suni cannot. Both can perform rituals, but only bimo can perform rituals linked to death. In most cases, suni only perform some exorcisms to cure diseases. Generally, suni can only be from humble civil birth while bimo can be of both aristocratic and humble families. Features. Deities. The Yi worship deified ancestors similarly to the Chinese traditional religion practitioners, besides gods of local nature: fire, hills, trees, rocks, water, earth, sky, wind, and forests. Rituals and practices. Ritual performances play a major role in daily  life through healing, exorcism, blessing, divination and analysis of one's relationship with the gods. They believe dragons (symbols of generation) protect villages against bad spirits. The Yi dragon is represented in Yi art differently from that in Han art. Beliefs and practices related to death and the afterlife. After someone dies, a pig or sheep is sacrificed at the doorway to maintain relationship with the deceased spirit. The Yi also believe in multiple souls. At death, one soul remains to watch the grave while the other is eventually reincarnated into some living form. Beliefs about spirits. The Yi believe  in numerous evil spirits. They believe that spirits cause illness, poor harvests and other misfortunes and inhabit all material things.
