Fragrant cloud yarn, commonly known as crowfoot silk, is a silk fabric woven by ancient hand dyeing and finishing techniques. In the dyeing process, the fragrant cloud yarn only uses the sap of the natural plant dioscorea and river mud containing high-valent iron ions, which is cool and pleasant, easy to wash and quick to dry. In 2008, Xiangyun yarn dyeing and finishing technology was included in the national intangible cultural heritage list.

The sericulture and silk reeling industry in Shunde District of Foshan City has a long history and is known as the "Southern Silk Capital". It has preserved the dyeing and finishing skills of Xiangyun yarn intact. During the Yongle period of the Ming Dynasty, Cantonese yarn was exported abroad. Fragrant cloud yarn has many advantages. It is very refreshing and moisturizing, has good sun and washing fastness, strong water resistance, easy to wash and dry, deep color and dirt resistance, non-stick to the skin, light and thin, not easy to wrinkle, soft and rich in bones. It is durable and suitable for hot summer wear. It is popular with consumers. It has been exported to Europe, America, India, Southeast Asia and other places. It has been hailed as "black glitter pearl" clothing by overseas people, and it has become a famous product of Chinese silk.Editor/Huang Lijun
