Lin Chong
Song Wan, along with Wang Lun and Du Qian, is first mentioned when the nobleman Chai Jin suggests to the former imperial troops instructor Lin Chong, who has killed three men sent by Grand Marshal Gao Qiu to murder him in Cangzhou, that he could take refuge in Liangshan. However, when Lin Chong arrives at the stronghold, Wang Lun is worried that Lin, a good fighter, could usurp his place. So he tries to send him away with gifts and excuses. But Du Qian, Song Wan and Zhu Gui, who runs an outlying inn which acts as a lookout for Liangshan, pleads on Lin's behalf. Wang Lun eventually allows Lin Chong to stay but keeps him at a low position.
