Song Jiang leads a military attack on Dongping while Lu Junyi conducts another on Dongchang, under the agreement that whoever achieves conquest first would be elected the chief of Liangshan. Song sends Yu Baosi, an acquaintance of Dong Ping, and Wang Dingliu to coerce the prefect to surrender the city and give up its food stock. The prefect is cowed, but Dong Ping calms him down and suggests executing the two to strike fear in the bandits. Not ready to mortally anger Liangshan, the prefect orders Yu and Wang be beaten and thrown out.
