Five years of excavation at Baoma in Antu County changed its identification from a walled settlement to a Jin-dynasty royal shrine for Changbaishan. Platforms, corridors, drains and roof ornaments show how the mountain’s ritual center was built.
A 2025 study compares charred wood from two elevations with a separate peat-core record to trace Changbaishan’s vegetation history. Charcoal from a high-elevation site now in alpine tundra supports an inference of spruce forest before the 946 eruption. The evidence also records a long ecological recovery. Changbaishan’s upper forest varies by slope, while a long-term plot follows forest conditions in Antu.
Tianchi fills Changbaishan’s summit caldera. UNESCO’s Geopark account describes the lake’s accumulation after an earlier eruption and its refill after the Millennium Eruption.
Excavators measured two enclosures, traced south gates and identified palace foundations on the Hunchun plain. Roof-tile fragments and early survey maps help reconstruct how Balhae’s Eastern Capital was organized between 785 and 794.
A basalt chamber, a broken granite stele and two stone lions preserve different parts of Princess Jeonghye’s burial story. Her posthumous title links the tomb to Balhae’s royal family, while an archaeological debate continues over the location of the kingdom’s early center.
Jingxin’s wetland, farmland and settlements form a working landscape used by migratory birds. Acoustic research tracked seasonal sound across three habitat types, while reporting on local patrols shows how rice cultivation and wildlife stewardship meet on the lower Tumen.
At Bailong Village, a stone marker sets a century-old house beside later visitor facilities. A loom, horse cart, welcome song and one dancer’s working week show how the village’s historical setting is also used for present-day work.
A 2023 revision to Yanbian’s language regulation sets rules for public signage; a Yanji publisher’s textbooks and dictionaries, and a prefectural process for reviewing new Korean translations, show how written language moves from noticeboard to print and digital media.
A Yanji-listed heritage craft begins well before winter: fish sauce, chili, garlic and cabbage arrive on different seasonal schedules. A regional product record describes how salted leaves are seasoned and fermented, while a 2025 public demonstration by inheritor Kim Songyue joins food-making to transmission.
A rice-sausage vendor’s two decades at Yanji’s Water Market lead to its 2026 move, while a New Year purchase at West Market links dried pollock to a family reunion. Together, the markets show two routes food takes through the city.
