Introduction to Longdong Temple: Longdong Temple is located halfway up the mountain on the east side of Kongwang Mountain, with a quiet courtyard. It was first built in the Eastern Han Dynasty, more than 1,400 years ago, and is one of the oldest temples in Lianyungang City. The temple houses the Four Heavenly Kings, Sakyamuni, and the Eighteen Arhats. Among them, the relics of Master Lun Kong who passed away here are the most prestigious treasures of the nunnery.
