  To identify cluster of societies and cultures is not easy in subject to the
availability of data. In this study, we propose a novel method to cluster
Chinese regional cultures. Using geotagged online-gaming data of Chinese
internet users playing online card and board games with regional features, 336
Chinese cities are grouped into 17 clusters. The distribution of clustering
units shows great geographical proximity when the boundary of the clusters
coincides well with the geographical boundary of provinces.
