There were many factional strife in Song dynasty. The strife between Xin-fa dang (新法黨) and Jiu-fa dang (舊法黨) was the most famous. Many scholars have researched these factions (Peng-dang朋黨), but they can’t prove what Peng-dang is. I also researched this theme and acquired the following result. Peng-dang was based on all sorts of daily life relationships including family, hometown, school, and occupation. These relationships united various political relationships and developed into Peng-dang. When I analyzed the network of Jiu-fa dang with the material of Chang-bian (長編), I acquired the following facts. Among Jiu-fa dang, Liu-zhi dang was the leading faction, and made use of avenues of criticism (言路官) in order to impeach Xin-fa dang and abolish most of bills made by Xin-fa dang. This time I analyzed the network of Liu-zhi dnag (劉摯黨) with epitaphs of Zhong-su ji (忠肅集) written by Liu-zhi. As a result of this research, I concludes that this network was based on the relationships of his birthplace and inhabitant place. He constructed various social networks such as regional relationships, blood relationships, marriage relationships, academic relationships, and occupational relationships by the medium of maternal people who lived in Yun-zhou(鄲州).
