Li Jin was famous in the Spring and Autumn Period and was the earliest cotton textile industry in China. Li Jin includes tube skirts, headscarves, flower ribbons, wrapping ribbons, bed sheets and quilts (called "Yazhou quilt" in ancient times). There are four major processes: spinning, weaving, dyeing and embroidery. Most of the colors are brown-black, blue, red, white, blue, yellow and other colors alternate with each other, which is suitable for preparation and rich in ethnic decorative flavor, forming exotic flowers, exotic grasses and exotic birds. Li Jin is thin, light, soft, white and durable, unparalleled in the Central Plains. "Li Jin is brilliant as a cloud" is the sincere praise of the ancients for Li Jin's craft. In ancient China, cotton was imported from India, South America and other places via Hainan Island by sea.
Before Song Dynasty, the cotton textile technology of Li nationality was far ahead of that of Han nationality in Central Plains. In the Yuan Dynasty, Huang Daopo improved the spinning and weaving technology of Li nationality and spread it to the mainland, which quickly promoted the development of cotton textile industry in the lower reaches of the Yangtze River, and set off a "cotton revolution" praised by scholars at home and abroad for hundreds of years, which made cotton fabrics replace linen as a necessity, and Huang Daopo became the ancestor of China textile industry. In ancient times, it was called Jibei cloth, Yazhou quilt and cotton cloth, which was a kind of characteristic cloth of Li nationality and was popular as far back as the Spring and Autumn Period. This is the earliest cotton textile in China. Li people use cotton wool and ramie fiber in kapok capsules, as well as shrub cotton such as island cotton, Brazilian kapok, continental cotton and kapok from the United States and India, mainly weaving embroidery and dyeing flowers, with less embroidery. Using natural plant pigment as pigment, a kind of special floral cotton cloth (linen and cotton as warp and weft respectively) is woven. Because kapok is also called northern Hebei, Li Jin is also called northern Hebei. Li Jin is thin, light, soft, white and durable. As the old saying goes, Li Jinzhao is like a cloud.
Before Song Dynasty, the cotton textile technology of Li nationality was ahead of that of Han nationality in Central Plains. Later, shrub cotton was gradually introduced into southern China from Hainan Island. In the Yuan Dynasty, Huang Daopo improved the spinning and weaving technology of Li nationality and spread it to the mainland, which quickly promoted the development of cotton textile industry in the lower reaches of the Yangtze River, set off a cotton revolution praised by scholars at home and abroad for hundreds of years, and made cotton fabrics replace linen fabrics as necessities of life. Huang Daopo has also become the originator of China's textile industry.
