The Yi leather lacquerware production technique is a marvel among the Yi lacquer arts. It takes cowhide and sheepskin as raw materials, and after dozens of processes, such as material selection, soaking, hair removal, shape making and ash, polishing, painting, drying, etc., it produces different types of living and military supplies for different needs. The Yi leather lacquer painting process is unique and skillful. The color lacquer is red, yellow and black. Their decorations are mainly taken from the plants and animals in the Bai Ran world, with patterns of sun, moon, stars, mountains, rivers, flowers, birds and trees, cows, goats, fish and insects, etc. The colored paintings are often not primed, and the painters draw naturally according to their own aesthetic experience of the cloth shape and layout, or simple or fine, or simple or dynamic, revealing the natural nature of the heart, and have a strong sense of ethnicity.
