The Iu Mien migrated from China during the 20th century, and mostly live as farmers growing cash crops like sesame and corn, raising poultry and pigs, and domesticating free-range cattle. Though they celebrate some Buddhist holidays, the Iu Mien practice a complex mix of animism, ancestor worship, feng shui, and magic based on Taoism, and the believe in some Lao Loum spirits such forest ghosts. Lu Mien speak their own language, and can be recognized by their dyed indigo clothes. The women wear embroidered skirts, turbans, and black blouses decorated with silver coins and ornaments, along with plenty of jewelry. When married, the wife moves into the groom’s family house, which holds up to 20 members, though immediate families have private space.
