Another four li to the east is a great dried-up pond, which is where King Virūḍhaka (formerly called Liuli) sank into the ground; people of later times erected a stūpa to commemorate it. There is also the place where Śāriputra competed with the non-Buddhists when first building the monastery, likewise marked with an erected stūpa.
