This series of photographs presents portraits of the Yi people residing in the heart of Liangshan Mountains in southwest China's Sichuan province. Historically, the Liangshan region served as the core area of the Yi people's slave society. After enduring millennia of such conditions, the local Yi society underwent a historic transformation in 1956 through democratic reforms, leaping directly from slavery to a socialist society—a leap that spanned a thousand years. This leap not only reshaped the Yi people's social structure but profoundly impacted their culture, customs, and ways of life—traditional attire (such as the charwa felt cloak and silver ornaments), religious beliefs (like the Bimo culture), and production methods (including slash-and-burn farming and animal husbandry) now face challenges of preservation and transformation amid modernization.
