The silk is the symbol of the anaent Chinese culture and the old silk in-dustry formed one of the glorious chapters in the history of the Chinese culture, making an indelible con-tribution to the development of the world cMlization. The Chinese silk is known throughout the world for its excellent qualities, exquisite colors and rich cultural connota-tions. Several thousand years ago, when the silk trade first reached Europe via the Silk Road,it brought with it not only the gor-geous silk apparel and decorcrtive items, but also the anaent and resplendent Oriental cMlization.From then on, silk was regarded as the emissary and symbol of the Oriental cMlization. The eadiest silk article discovered to date is approximately 4700 years old, un-earthed from a tomb dating from China’s Liangzhu Culture. According to an ancient Chinese legend, the Silkworm Goddess appeared to the Yellow Emperor, the leg-endary ancestor of the Chinese people, after he vanquished his adversary Chi You.She presented him with silk fibers spun from her own mouth as a sign of respect.The Yellow Emperor ordered the fibers woven into cloth and made into the silk ap-parel, which he found exceedingly soft and comfortable. His wife Lei Zu searched until she found a type of caterpillar capable of spinning silk fibers from its mouth.She raised these silkworms by feeding them mulberry leaves she picked herself.Later generations came to worship Lei Zu as the Silkworm Goddess, and the Yellow Emperor as the God of Weaving. Sericulture, including cultivating the mulberry plant, raising silkworms, and producing silk fabric, was a fundamental form of la-bor throughout thousands of years in ancient China. China is the birthplace of seri-culture. Raising silkworms and reeling the silk from their cocoons was ancient China’s greatest achievement in the utilization of natural fibers.
