     Yinxu (Ruins of Yin) is the ruins of the last capital of China’s Shang Dynasty (1600 BC - 1046 BC). The capital served 255 years for 12 kings. It shows the golden age of early Chinese culture, crafts (工艺品) and science, a time of great prosperity (繁荣) during the Chinese Bronze Age (青铜时代).

Discovered in 1899, Yinxu is one of the oldest and largest archeological sites (考古遗址) in China and is one of the historical capitals of China and is listed as a UNESCO World Heritage Site. It lies in central Henan Province, near the modern city of Anyang, and is open to the public as the Garden Museum of Yinxu. It is famous as the source of oracle bone script (甲骨文), the earliest recorded form of Chinese writing. The oracle bone script has recorded almost everything from dream-explaining to events such as harvests, birth of a child, the weather and the success of military campaigns.

Over 3,000 tombs, 2,200 pits, and 200 houses have been dug out at Yinxu. The large number of burial accessories found there shows the high level of the Shang crafts industry.The site includes a main palace and an ancient tomb. Besides, there are a number of large buildings, at least 53 of which have been dug out.
