Archaeologists have further excavated the Liuzhuang relic site in Hebi city, Central China's Henan province.

More than 200 tombs have, so far, been unearthed, with various funeral objects discovered. The items include tomahawks, strings of turquoise stone beads, ancient cooking vessels and basins.

The most recent archaeological discovery mainly featured the Dasikong type of Yangshao culture, which dates from 4,900 to 5,100 years ago. These were widely distributed in the region of northern Henan and southern Shanxi.

Liuzhuang ruins were first discovered in 2005, covering more than 300,000 square meters.

The discovery filled up the blank of research on pre-Shang cultures and provided clues to the origin of the Shang people.
