Bimoism 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.
