According to the stratification and artifacts, the site can be separated into early and late periods. The early period was mainly found at the Bogonglong, Yuehu (月湖), and Fenliao Shuiwei (粉寮水尾) sites. Artifacts are scattered in the red clay layer of the red clay gravel plateau from the Pleistocene period in these areas. The artifacts consist mainly of flake tools. The stone tools unearthed generally consist of larger knapped and chipped stone tools which were used mostly for chopping, hacking, throwing, or flaking, the chopping device culture of the Pleistocene Period. Gathering resources was an important production method at that time. As for the precise time, according to the relative dating of the colluvium formation, the Bogonglong site dates back to 8,250 to 47,000 years ago.
The later period was mostly found at the Bogonglong, Lisiping (壢西坪), and lower layer of the Yuanshan (圓山) Site. The artifacts that were found were in the red clay level of the red clay gravel plateau formed in the Pleistocene Period around those areas. The artifacts include mainly small flake scrapers and a great amount of flake waste and stones. As for the technique, it appears to have become more sophisticated and detailed as compared to the early period, which is evident in the numerous flaking surfaces on the tools. These scrapers are usually left with a bit of stone skin and are produced in a standard way. In addition, prehistoric humans usually used the sharp edges of untrimmed blades, which had significant wear and tear marks when unearthed. Since these tools were mainly used for scraping and cutting, and given the location of these sites, it is safe to say that hunting was one of the main way of living at that time. The small amount of large stone tools might demonstrate the possibility of resource gathering on land.
According to the relative dating of the colluvium formation of the Bogonglong Site, it dates back between 8,250 and 6,000 years ago. Wangxing Culture has produced a large amount of small stone-made artifacts, but since it is difficult for organisms to be preserved in red clay, there has not been any evidence of organic matter. However, from the pottery findings, a certain understanding can be had about the cultural connotations of the owners.
