Archaeologists recently excavated prehistoric settlements dating back to early Neolithic (9,000 to 8,000 years ago) in the Peiligang Cultural layer of Tang Period at 13 kilometers south Xinzheng City, Henan Province of China. It is not only the first time for China to excavate such a large prehistoric area, but also is the first time to discover a 'double-room' house (a large and a small).
     Zhang Songlin, director of the Zhengzhou Cultural Relics and Archaeological Institute said that the unearthed site include 60 houses, covering more than 6,000 square meters. It is divided into three groups, about 20 for each. At the regional center of each group, there is the so-called 'double-room' house, which was most likely belonging to important figures in the ethnic groups.
