The ancient loom was invented by Huang Daopo. During the reign of Emperor Lizong in the Southern Song Dynasty, Huang Daopo, who was only 13 years old, drifted to Shuinan Village in Yazhou with a merchant ship to escape being a child bride. At that time, Li people's cotton textile technology was ahead of that of the Han people in the Central Plains, so Huang Daopo fell in love with Li people to learn how to spin with wood cotton wool, use rice wine, coconut water, bark and wild plants as pigments to color and dye threads, and use the textile printing and dyeing technology of loom heald, weaving flowers and weaving, and invented the pedal "three-burst and three-thread" spinning car and "ju-weaving waist machine" loom 400 years earlier than Europe. The patterns of Li Jin and tube skirts woven by "treading the vertebral arch" are gorgeous and elegant, including more than 200 kinds of chicken patterns, ponytail patterns and frog patterns, which are known as "the machine is exquisite and the flowers are thousands of flowers".
