The history of silk manufactiring in China is very long . The oldest silk found in China can trace back to about 3630 BC,－from the Chinese Neolithic period. This silk was found in the Henan Province, a region widely regarded as the cradle of Chinese civilization.
Another example of very old silk in China is a group of silk threads, a braided silk belt and a woven silk cloth fragment dated to circa 2570 BC. These items were excavated from the Liangzhu culture site at Qianshanyang, in the Zhejiang Province. The Liangzhu was the last Neolithic jade culture in the Yangtze River Delta.
The oldest known written reference to silk is on a bronze fragment found at the Shang Dynast site at Anyang. The Shang Dynasty existed from circa 1600 to circa 1050 BC.
