Baoma lies near Erdaobaihe on Changbaishan’s northern side, in Antu County. Earlier interpretations treated it as a walled settlement used from the Balhae period into the Liao and Jin eras. Excavations from 2014 through 2018 changed the identification: archaeologists recognized the site as a Jin-dynasty shrine built by the royal family for worship of Changbaishan.
The revised interpretation came from mapping buildings and reading finds together. A Jilin University report in August 2018 described nineteen faculty and students working at the site during a hot spell, while a field station was nearing completion. Across seasons, teams traced platforms, halls and connections between buildings. Field records turned a broad settlement label into a more specific account of a royal ritual center.
