Prehistoric Cultures
By 10,000 B.C., a group of Neolithic people called the Yangshao had settled in north central China. They chose a place where one of China's major rivers, the Huang He, meets another river, The Wei.
Archaeologists have discovered remains of Yangshao houses. They had plastered roofs where held up by wooden posts.
A second Neolithic culture, the Lungshan harvested silk from from silkworms, wove fabric, made pottery, and used simple written symbols. In order to farm near the river they had to work together on flood control and irrigation projects.
