After fleeing Mengzhou, Wu Song runs into Sun Erniang and Zhang Qing again, who advise him to go to Mount Twin Dragons to join the outlaw band there. Sun suggests that he disguise as an untonsured Buddhist pilgrim to avoid being recognised since his wanted notice bearing his portrait is posted everywhere. Earlier on, Sun had butchered a Buddish pilgrim, who left behind a Buddhist robe, a necklace of skulls, a headband and a pair of broadswords. Wu Song puts on the robe and lets down his hair, as Buddhist pilgrims do, thus concealing the exile tattoo on his face. He is thenceforth nicknamed "Pilgrim".
