5. Early porcelain kiln site in Shaoxing City, Zhejiang. Nearly 200 kilns dating back to 1,700 years ago with a large number of celadon porcelain artifacts were unearthed. The kilns were built in the Eastern Han Dynasty (25-220), Three Kingdoms period (220-265), and Western Jin Dynasty (265-316) respectively.

It is the first time Chinese archeologists have discovered ancient kilns of different time periods at the same site. Tonnes of celadon, the signature Yue Kiln product, have been excavated from the site. The wares are of various shapes and are with high quality glaze and exquisite craftsmanship.

The Yue Kilns, which are mainly in Zhejiang Province, were among the world's oldest porcelain kilns. Since the earliest known Yue kilns appeared during the late period of the Eastern Han Dynasty,celadon had seen robust development for about a millennium. The celadon, usually in pale green color, is often compared to jade. [Photo/Xinhua]
