By 14C dating the dates of the relics were between 7800-7355(±65) B.P., i.e., about 1000 years earlier than Banpo type of the Yangshao culture.Moreover, carbonated seeds of grains were found in the No. 1-period ash pit. They were ascertained to be the earliest crops of dry farming in China.One of the earliest agriculture of China is considered originating in the Qingshui River Valley of the Jinghe River and the Weihe River drainage. Then it expanded, ra-diately, to the Guanzhong basin, Huanghe River Delta, Changjiang River drainage, southward to the Zhujiang River Delta and the Guangxi Basin, northeast ward to the Song-liao Plain and northwest ward through the Hexi Corridor to the Xingjiang oases.更多还原
