Six Pagodas Ancient Tombs Complex

　　The Six Pagodas Ancient Tombs Complex served as the burial ground for the royal family of the Bohai Kingdom during its early Tang-influenced period. The Bohai Kingdom was a regime established in 698 AD by the Mohe people, centered around the Mudan River basin. Emperor Xuanzong of the Tang Dynasty conferred the title of "Prince of Bohai" upon its ruler and established the Hukan Prefecture in the region, setting up the Hukan Prefecture (Bohai) Military Governor's Office. The Bohai Kingdom maintained frequent exchanges with the inland areas of China, adopting many of the Tang Dynasty’s systems and institutions. Its socio-economic and cultural development reached a considerable level before it was conquered by the Khitan in 926. Archaeological excavations of the tomb complex were carried out by Yanbian University in 1949, the Jilin Provincial Museum in 1959, and the Institute of Archaeology of the Chinese Academy of Sciences in 1964.

　　Liudingshan Mountain runs from east to west and consists of six contiguous, undulating peaks, with the highest peak reaching an elevation of 603 meters. From the southeast side extends a mountain spur, on both sides of which lie the tombs—over 90 ancient tombs in total. The tombs are divided into two types: stone chamber tombs and stone coffin tombs.

　　The tomb of Princess Zhenhui, excavated here in 1949, belonged to the daughter of Dae Cheonmu, the third king of the Bohai Kingdom. Artifacts unearthed from the tomb include pottery, jade discs, gilded bronze ornaments, and a memorial stele. The stele is gui-shaped, measuring 90 cm in height, 49 cm in width, and 29 cm in thickness. The inscription, carved in intaglio Chinese characters in regular script, spans 21 lines and contains over 700 characters. It dates back to 780 AD. The inscription reveals that the Bohai Kingdom used Chinese characters, favored parallel prose, and had a refined tradition of calligraphy, all of which hold significant historical value. The tomb chamber is rectangular, with walls built from layered lava and basalt stones. The ceiling features a corbelled dome structure, covered with large stone slabs. A passageway is situated in the middle of the southern wall, leading to a front corridor. Both the tomb chamber and the corridor are paved with floor tiles.

　　The Six Pagodas Tomb Complex and its unearthed relics reflect the material culture and social conditions of the early Bohai Kingdom, serving as important materials for the study of its history. In March 1961, the Six Pagodas Ancient Tombs Complex was designated by the State Council as one of the first batch of Major Historical and Cultural Sites Protected at the National Level.
