Introduction to gold-weaving technology: A gold-woven long-sleeved robe from the Yuan Dynasty is the earliest known example of Yunnan brocade gold-weaving technology. The Yuan people inherited the gold-using custom of the nomadic people and moved more than 3,300 households of brocade workers from the Western Regions captured during the Western Expeditions into the inland. They mass-produced "Nalosi Stone" gold brocade, which was used for the robes of the royal family and officials, and even The tabernacle was also woven with gold. Nanjing brocade is a fabric that uses a lot of gold and was developed on the basis of inheriting the gold brocade of the Yuan Dynasty. At first glance, the gold-woven long-sleeved robe is unremarkable, but upon closer inspection, the robe carries the rugged style of the grassland nomads, and the delicate weavers cannot be concealed. The patterns woven with gorgeous gold threads faintly reveal nobility.
