Xiaoke Longshan Cultural Site is located 250 meters east of Xiaoke Village, Beizaoxian Township, Zhengding County, spanning Xiaoke and Beizaoxian villages. It stretches about 320 meters from east to west and 100 meters from north to south.

Polished black pottery, grey pottery, red pottery and sandy red pottery shards have been discovered and collected on the cliff sections of the site, along with stone, bone and shell artifacts. Identifiable relics include pottery li tripods, large-mouthed zun vessels, large urns, pottery dou stemmed bowls, jars, stone axes, stone shovels, stone adzes, stone pestles, shell saws and oracle bones. The artifacts are decorated with basket patterns, cord patterns, comb patterns, nail impressions, square patterns and concentric circles. The site has been verified as a Longshan Culture relic.

Today, the site and its surrounding areas are all farmland, and occasional early cord-marked pottery shards can still be found here. It was designated a Major Historical and Cultural Site by the People's Government of Hebei Province on July 23, 1982.
