  To identify cluster of societies is not easy in subject to the availability
of data. In this study, from the prospective of computational social science,
we propose a novel method to cluster Chinese regional cultures. Using millions
of geotagged online-gaming data of Chinese internet users playing online card
and board games with regional features, 336 Chinese cities are grouped into
several main clusters. The geographic boundaries of clusters coincide with the
boundaries of provincial regions. The north regions in China have more
geographical proximity, when regional variations in south regions are more
evident.
