The site was excavated in 2010 by the Department of History of Science & Scientific Archaeology of University of Science & Technology of China. A total of 400m2 of the site was exposed during this excavation, which unearthed 202 stone artifacts. The stone assemblage includes cores, flakes, retouched tools, chunks and split. The most prominent raw materials utilized in this site were quartz cobbles to produce small or medium sized flakes and retouch tools. The principal flaking technique was direct percussion hammering and bipolar flaking. Two types of retouched flake tool were identified, an End-scrapper, and a Semi-side Scrapper. They resemble Northern Chinese Paleolithic lithic assemblage elements. The Stratigraphic and topographic comparison with other site indicated that the site was most likely formed during the Middle Pleistocene.

The excavation exposed an area of 400m2. A total of 225 stone artifacts were unearthed. The stone assemblage includes cores, fl akes, retouched tools, chunks and split and so on. Human mainly used quartz cobbles to fl ake and retouch tools. The principal fl aking technique was direct hammer percussion.Most stone artifacts were small or medium in size. Pebble retouched tools were dominated, especially choppers. Most tools were retouched in one end of the pebble. The characteristics contained South China Paleolithic industry elements, as well the fl ake tools were in appearance.The Stratigraphic and topographic comparison with other site showed that the site likely formed in the Middle Pleistocene.

Rice and millet agriculture development in Chengdu Plain then spread quickly to northwestern Yunnan, Guizhou and Guangxi, eventually the Indo-China Peninsula.

Through analysis of discovered remains of ancient rice (Oryza sativa) and millet
(Setaria italica) and their connections with environmental conditions and archaeological cultures, this paper analyzes the dynamic progress of early agriculture in China, which can be divided into five stages. The authors believe that the traditions of growing rice in the south and millet in the nor th were established at the earliest stage. This process involves a gray area where both crops were grown. At different stages, this area moved with the changes in climate and environmental conditions. In the Yellow River valley, the spread of rice and wheat
(Triticum aestivum L) and the indigenous millet, broomcorn millet (Triticum aestivum L) and beans (Leguminosae) formed a subsistence model of dry farming. In the Yangtze River valley, as the proportion of gathering in the economy decreased with the development of rice production, a dif ferent but comparatively stable subsistence model was formed based on rice growing (principally), hunting, fishing and gathering.
