Longtoushan Ancient Tombs

　　The tomb complex covers an area approximately 500 meters in length from east to west and 400 meters from north to south, with 12 earthen burial mounds visible on the surface. In front of the largest tomb stand two large stone pillars, and the flat land to the south contains the foundations of buildings.

　　One of the excavated tombs belongs to Princess Zhenxiao, the fourth daughter of Dae Heungmu, the third king of the Bohai Kingdom. Built in the late 8th century, the site originally had a brick pagoda, which has since collapsed, leaving only the tomb chamber. The most precious finds are the 12 mural figures painted inside the tomb — the first discovery of Bohai murals. On the east and west walls of the tomb passage are paintings of warriors, while the rectangular main chamber features four attendants on each side and two more on the rear wall. The warriors are depicted in armor, and the attendants wear traditional headwear (futou) and elegant robes. These colorful figures, with their rounded forms and skilled brushwork, reflect the painting style of early Tang Dynasty and demonstrate the influence of the highly developed Central Plains culture on the frontier ethnic groups. The tomb chamber walls are constructed of bricks and sealed with large stone slabs. A tomb epitaph was unearthed, inscribed with Chinese characters in regular script, recording the life of Princess Zhenxiao. (National Cultural Heritage Administration)
