Gongsun Sheng
Song Jiang sends Dai Zong to get Gongsun Sheng, who has been away for too long to visit his mother in Jizhou (薊州; present-day Ji County, Tianjin), back to Liangshan. Yang Lin, a lone wanderer, bumps into Dai at a narrow lane and immediately could tell from the latter's speedy pace that he must be the famous "Magic Traveller". So Yang calls out the nickname of Dai, who is a bit shocked to be identified by a stranger. He stops to speak to Yang, who is most ready to join Liangshan when Dai invites him.
