Ancient silk fabrics have been unearthed, as remnants of the long-gone Liangzhu culture, which dates back 4,700 years. At that time, Chinese ancestors had acquired methods of planting mulberry trees, cultivating silk, reeling woven silk thread, and making tools for reeling. Thus, Hangzhou silk has a long history. One thousand years ago, silk made in Hangzhou was being exported to Southeast Asia and Arabia, and the Silk Road was laid down at this time. In the 1st Century, Cleopatra, the last Queen of Egypt – along with other prominent Romans of the time - were infatuated with Chinese Silk, much of which came from Hangzhou. The Chinese Silk City, which is located at the center of the Hangzhou, is now the largest professional wholesale and retail silk market in China.
