Guan Sheng
Folk stories about Song Jiang circulated during the Southern Song. The first known source to name Song Jiang's 36 companions was "Miscellaneous Observations from the Year of Guixin" (癸辛雜識) by Zhou Mi, written in the 13th century. Among the 36 are Lu Junyi, Guan Sheng, Ruan Xiao'er, Ruan Xiaowu, Ruan Xiaoqi, Liu Tang, Hua Rong and Wu Yong. Some of the characters who later became associated with Song Jiang also appeared around this time. They include Sun Li, Yang Zhi, Lin Chong, Lu Zhishen and Wu Song.
