公孫勝
Dai Zong has incidentally come to know Yang Lin when he tries to locate Gongsun Sheng, who has returned to his hometown of Jizhou to visit his mother, to get him back to Liangshan as instructed by Song Jiang. The two pass by Yinma River (飲馬川; in present-day Ji County, Tianjin) and are blocked by a bandit group led by Deng Fei and Meng Kang. It turns out that Yang and Deng are acquaintances. They are introduced to the chief Pei Xuan, who agrees to merge his band into that of Liangshan.
