After Baekje fell, leaders including Boksin and Dochim brought back Prince Buyeo Pung and launched a restoration movement. Ugeumsanseong behind Gaeamsa is a leading site identified as the possible Juryuseong headquarters, and Buan County presents it as a final center of resistance.
The exact location of Juryuseong has not been conclusively settled by scholars. The Boksin Cave story at Ugeumbawi should likewise be understood as local tradition rather than confirmed history.
