蚕丝业的发展

Silk was discovered by the Chinese more than 3,000 years ago. It was said that the wife of the Yellow Emperor accidentally dropped a silkworm cocoon(蚕茧) into her tea. The hot water caused the cocoon to break. As it broke apart, she realized its beauty. From then, the silk industry began. At first, only the rich were allowed to wear silk.

As early as 300 AD, Chinese businessmen were seling silk to the Indians. By 200 BC, the Koreans had learned how to make silk. A 12,000­kilometre road going from China to Europe was built because of silk. From there, knowledge of silk production spread across the world.

Here's a simple version of how this amazing little thing does its work. The silkworm begins life as a moth(蛾). The moth's life is about ten days, during which it lays eggs that change into silkworms. Silkworms eat a lot. In their short lives, 20,000 silkworms will eat more than one ton of mulberry(桑树) leaves, their main food. In its final stage of life, the silkworm spins a cocoon. The finished cocoon contains 350 metres of silk. That might seem like a lot, but consider this: 5,500 silkworms have to spin 5,500 cocoons to make one kilogram of silk. People raise silkworms for silk production. The Chinese have perfected the art of making silk, gaining knowledge over many centuries.

Today, silk production remains an important economic risk in China. While versions have recently entered the market, the beauty of naturally produced silk is not matched. Silk no longer costs an arm and a leg, but it is still highly prized.
